Question 1Motor development, motor learning, and movement skill acquisition
During early childhood, gross motor control of the trunk and arms typically precedes fine control of the fingers. Which principle of motor development best explains this pattern?
- Regression followed by recapitulation
- Differentiation and integration of reflexes
- Critical period specificity
- Cephalocaudal and proximodistal progression Correct answer.
Explanation
Motor development generally follows cephalocaudal (head-to-tail) and proximodistal (center-to-outward) directions. Consequently, control of the trunk and upper arms emerges before refined finger control. This principle helps teachers sequence tasks from gross to fine.
Question 2Motor development, motor learning, and movement skill acquisition
A physical education teacher classifies a basketball free throw and a 5-kilometer run for instructional planning. Which classification pair correctly labels these skills?
- Free throw = discrete; 5-km run = continuous Correct answer.
- Free throw = serial; 5-km run = discrete
- Free throw = continuous; 5-km run = serial
- Free throw = continuous; 5-km run = discrete
Explanation
Discrete skills have a recognizable start and finish, whereas continuous skills are repetitive with no clear endpoints. A free throw is a single action with a defined beginning and release; a distance run is cyclical and ongoing. Classifying skills this way supports appropriate instructional design.
Question 3Motor development, motor learning, and movement skill acquisition
After a student performs a volleyball serve, the teacher says, “Your toss was 30 centimeters too far forward.” This statement is best classified as which type of feedback?
- Knowledge of results about the serve outcome
- Knowledge of performance about the movement pattern Correct answer.
- Knowledge of results about the toss height
- Intrinsic feedback about the force of the hit
Explanation
Knowledge of performance gives the learner information about the movement pattern itself, such as toss placement. Knowledge of results describes the outcome, and intrinsic feedback comes from the performer's own senses. The teacher's comment targets the process, not the score.
Question 4Motor development, motor learning, and movement skill acquisition
A learner practicing a tennis forehand can consistently make contact but still refines timing and reduces errors from shot to shot. According to Fitts and Posner's stages of motor learning, which stage is this learner most likely in?
- Associative stage, because the skill is being refined Correct answer.
- Cognitive stage, because errors remain frequent and inconsistent
- Autonomous stage, because the skill has become automatic
- Reflexive stage, because timing is being refined
Explanation
In Fitts and Posner's associative stage, learners refine technique, reduce errors, and consolidate the skill. The cognitive stage involves frequent, inconsistent errors, while the autonomous stage is marked by automatic performance with little attention. The described learner fits the associative stage.
Question 5Motor development, motor learning, and movement skill acquisition
A teacher modifies ball size and court width to help students succeed at a striking task. In Newell's constraints model, these modifications primarily manipulate which category of constraint?
- Sociocultural constraints
- Individual constraints
- Task constraints Correct answer.
- Environmental constraints
Explanation
Newell's model divides constraints into individual, task, and environmental categories. Task constraints include equipment, rules, and the goal of the activity; changing ball size or court width modifies the task. Individual constraints refer to learner characteristics, and environmental constraints refer to the physical or sociocultural setting.
Question 6Motor development, motor learning, and movement skill acquisition
A coach alternates forehand, backhand, and volley practice in an unpredictable order during each session. This schedule is best described as which practice condition, and what is its typical effect?
- Distributed practice, which typically reduces interference between skills
- Random practice, which typically enhances retention and transfer Correct answer.
- Blocked practice, which typically improves practice performance more than retention
- Massed practice, which typically enhances retention by increasing volume
Explanation
Random practice intermixes different skills in an unpredictable order, creating contextual interference. This typically lowers performance during practice but improves retention and transfer compared with blocked practice. Massed and distributed practice refer to rest scheduling, not skill sequencing.
Question 7Motor development, motor learning, and movement skill acquisition
A student who has learned to throw a baseball accurately picks up a tennis ball and throws it with a similar overhand pattern. This is an example of which phenomenon?
- Bilateral transfer, because both arms are used in the action
- Positive transfer, because prior learning supports the new task Correct answer.
- Negative transfer, because the equipment and sport differ
- Zero transfer, because the two sports are unrelated
Explanation
Positive transfer occurs when previous learning facilitates performance or learning of a new skill. The similar overhand throwing pattern supports the tennis throw, so the effect is positive. Negative transfer interferes, zero transfer has no effect, and bilateral transfer involves transfer between limbs.
Question 8Motor development, motor learning, and movement skill acquisition
Which description best matches an open motor skill?
- A skill performed in a stable environment where the performer controls timing
- A skill performed without any form of feedback during execution
- A skill with a clear beginning and end and no environmental variation
- A skill performed in an unpredictable environment requiring adaptation Correct answer.
Explanation
Open skills are performed in unpredictable, changing environments, so performers must adapt their actions to external conditions. Closed skills occur in stable, predictable settings where the performer controls timing. The other options describe closed or unrealistic conditions.
Question 9Motor development, motor learning, and movement skill acquisition
According to Schmidt's schema theory, which statement best describes the role of the recall schema when a learner performs a novel variation of a throwing skill?
- It evaluates the sensory consequences of the movement after completion and stores them
- It stores only the specific movement time for one practiced throw
- It selects parameters for the generalized motor program to achieve the goal Correct answer.
- It replaces the generalized motor program with a new reflex
Explanation
In Schmidt's schema theory, the recall schema selects parameter values for a generalized motor program to achieve a desired outcome. The recognition schema evaluates sensory consequences after the movement. Schema theory does not replace motor programs with reflexes or store only one fixed movement time.
Question 10Motor development, motor learning, and movement skill acquisition
A coach wants to introduce highly technical weightlifting movements to young athletes. Which interpretation of developmental readiness is most consistent with current motor development research?
- Readiness can be ignored because technical skills are fully transferable at any developmental stage of the athlete
- Readiness combines physical growth, motor competence, and psychological maturity, so individual assessment should guide progression Correct answer.
- A critical period for weightlifting closes at puberty, so earlier introduction always guarantees later elite performance
- Readiness is determined solely by chronological age, so all athletes of the same age should begin training together
Explanation
Current motor development research treats readiness as multidimensional, involving physical growth, motor competence, and psychological maturity. Coaches should assess individual athletes rather than relying on chronological age alone or claiming a fixed critical period. Technical training should be progressed according to the learner's current capacities.
Question 11Motor development, motor learning, and movement skill acquisition
Which of the following is classified as a manipulative fundamental movement skill rather than a locomotor or stability skill?
- Skipping
- Catching Correct answer.
- Running
- Balancing
Explanation
Manipulative fundamental movement skills involve giving force to or receiving force from an object, such as catching, throwing, or striking. Running and skipping are locomotor skills, and balancing is a stability skill. Catching is therefore the manipulative item.
Question 12Motor development, motor learning, and movement skill acquisition
According to Fitts and Posner's stages of motor learning, which characteristic is most typical of a learner in the cognitive stage?
- The learner adapts the skill easily to unpredictable game situations.
- The learner makes many errors and depends on explicit instruction. Correct answer.
- The learner detects and corrects most errors without teacher feedback.
- The learner performs the skill consistently, automatically, and without conscious thought.
Explanation
The cognitive stage is the initial stage of learning, when the learner is trying to understand the task and makes many errors. Explicit instruction, demonstration, and feedback are especially important because the learner cannot yet self-correct reliably. Automatic and highly adaptable performance comes later in the associative and autonomous stages.
Question 13Motor development, motor learning, and movement skill acquisition
In motor learning, which practice schedule distributes trials across multiple sessions or includes relatively long rest intervals between trials?
- Massed practice
- Distributed practice Correct answer.
- Blocked practice
- Variable practice
Explanation
Distributed practice spreads practice trials over time or inserts longer rest intervals between trials. Massed practice involves little rest, while blocked and variable practice describe the order of tasks rather than the distribution of rest. The defining feature here is the spacing of practice.
Question 14Motor development, motor learning, and movement skill acquisition
A physical education teacher wants to improve students' learning of a soccer instep pass by using a peer model. Which condition is most likely to enhance observational learning?
- A much older model performs a different sport skill.
- An expert model performs the skill with no explanation or cues.
- A similar-age peer demonstrates correctly and receives praise. Correct answer.
- A model demonstrates once while students are distracted.
Explanation
Observational learning is stronger when the model is similar in age or status, demonstrates correctly, and is reinforced. A praised similar peer is likely to hold the learner's attention and increase imitation. Expert models without cues, older models performing different skills, and distracted demonstrations weaken attention and retention.
Question 15Motor development, motor learning, and movement skill acquisition
A teacher instructs a student learning the standing long jump to 'push the floor away and land softly.' This cue is best described as promoting which type of attentional focus?
- Dissociative focus on unrelated thoughts
- Closed-loop focus on proprioceptive feedback
- External focus on movement effects Correct answer.
- Internal focus on body movements
Explanation
An external focus directs attention to the effects of movement on the environment, such as pushing the floor or landing softly. An internal focus would direct attention to body parts, such as extending the knees. Dissociative focus is unrelated to the task, and closed-loop focus is a control process, not an attentional focus category.
Question 16Motor development, motor learning, and movement skill acquisition
A teacher is planning practice for a gymnastics floor routine that contains several skills linked in a fixed sequence with high interdependence. Which practice approach is most appropriate?
- Practice each skill only in isolation until perfect, then never practice the full routine.
- Use random practice exclusively across unrelated units.
- Use part practice for the entire season without linking the parts.
- Use whole practice because the parts are highly organized and interdependent. Correct answer.
Explanation
Whole practice is generally preferred when a skill has high organization and the parts are highly interdependent, as in a linked gymnastics routine. Part practice is more useful when the skill can be separated into relatively independent components. Isolating parts without ever linking them or using unrelated random practice would not prepare the learner for the integrated routine.
Question 17Motor development, motor learning, and movement skill acquisition
A student throws a beanbag at a target. The target is moved farther away and made smaller. According to Fitts' law, what change is expected in movement time if the student tries to maintain accuracy?
- Movement time will increase only if the student uses a lighter beanbag.
- Movement time will increase because the index of difficulty is higher. Correct answer.
- Movement time will decrease because the task is more demanding.
- Movement time will remain unchanged regardless of target difficulty.
Explanation
Fitts' law states that movement time increases as the index of difficulty rises, which happens when the target is smaller or farther away. The index of difficulty is based on distance and target width, not on object weight. Maintaining accuracy on a harder target therefore requires more time.
Question 18Motor development, motor learning, and movement skill acquisition
In dynamic systems theory, a rate limiter is best described as which of the following?
- A stable movement pattern that always emerges automatically.
- A type of augmented feedback given after every trial.
- A practice schedule that randomizes all trials.
- An individual constraint that limits a new motor skill. Correct answer.
Explanation
In dynamic systems theory, a rate limiter is an individual constraint, such as strength, balance, or motivation, that slows or blocks the emergence of a new motor skill. It is not a stable pattern, a feedback schedule, or a practice order. Identifying the rate limiter helps a teacher target the constraint that is holding the learner back.
Question 19Motor development, motor learning, and movement skill acquisition
When a beginner first learns a new striking skill, the learner often fixes the wrist and elbow and uses only the shoulder. According to Bernstein's degrees-of-freedom concept, what does this pattern most likely represent?
- Autonomous stage performance with flexible synergies
- Freezing degrees of freedom to simplify coordination Correct answer.
- Freeing degrees of freedom to exploit reactive forces
- A permanent inability to learn the skill
Explanation
Bernstein proposed that beginners initially freeze degrees of freedom to reduce the complexity of coordination. As skill develops, learners free degrees of freedom and exploit reactive forces more flexibly. Fixing the wrist and elbow while using only the shoulder is a classic early freezing strategy, not a permanent limitation.
Question 20Motor development, motor learning, and movement skill acquisition
A teacher gives feedback only when a student's jump distance falls outside a range of acceptable performance, such as plus or minus 10 centimeters from the target. This is an example of which feedback strategy?
- Bandwidth feedback Correct answer.
- Knowledge of results after every trial
- Summary feedback
- Haptic feedback
Explanation
Bandwidth feedback is given only when performance falls outside a predetermined tolerance range, so the learner receives feedback when a correction is needed. Giving knowledge of results after every trial is more frequent, summary feedback is given after a set of trials, and haptic feedback is tactile. Bandwidth feedback can encourage self-assessment and reduce dependence on the teacher.
Question 21Motor development, motor learning, and movement skill acquisition
A volleyball player jumps to spike and commits to a fast, ballistic arm swing that cannot be altered after it begins. This action is best described as relying primarily on which type of control?
- feedback control that corrects the movement during execution
- serial control that depends on visual reaction time
- closed-loop control guided by ongoing sensory feedback
- open-loop control driven by a prestructured motor program Correct answer.
Explanation
Open-loop control is used for rapid, ballistic actions in which the movement is planned in advance and executed without time for feedback correction. The spike arm swing is too fast for ongoing sensory feedback to modify it, so a prestructured motor program governs the action.
Question 22Motor development, motor learning, and movement skill acquisition
An infant's fingers flex and grasp when the palm is stroked. This response is which primitive reflex?
- rooting reflex
- asymmetric tonic neck reflex
- Moro reflex
- palmar grasp reflex Correct answer.
Explanation
The palmar grasp reflex is elicited by stroking the infant's palm, producing finger flexion and grasping. It is a primitive reflex that typically integrates during infancy as voluntary grasp develops.
Question 23Motor development, motor learning, and movement skill acquisition
A young child hops with a rigid trunk, limited arm swing, and frequent loss of balance. In the developmental sequence of fundamental movement skills, this performance best represents which stage?
- elementary stage
- proficient stage
- mature stage
- initial stage Correct answer.
Explanation
The initial stage of fundamental movement skill development is marked by restricted, poorly coordinated body action, limited arm swing, and inconsistent balance. Later stages show greater coordination, rhythm, and adaptability.
Question 24Motor development, motor learning, and movement skill acquisition
After a student's jump shot, the teacher says, 'You released the ball after your knees had already straightened; release it as your legs extend.' This statement is best classified as which type of feedback?
- knowledge of results
- knowledge of performance Correct answer.
- summary feedback
- bandwidth feedback
Explanation
Knowledge of performance gives information about the movement pattern or technique used to produce the outcome. The teacher describes the timing of ball release relative to leg extension, which is technique information rather than a simple outcome score.
Question 25Motor development, motor learning, and movement skill acquisition
A teacher observes that students' passing accuracy improves steadily during a practice session and wants to determine whether actual learning has occurred. Which assessment approach is most appropriate?
- add more repetitions of the same drill in the current lesson
- ask students to rate their confidence after the session
- use a delayed retention test and a transfer test in a new context Correct answer.
- retest immediately at the end of the same practice session
Explanation
Learning is inferred from relatively permanent changes in capability, so it is better assessed after a rest interval and in a changed context. A delayed retention test reduces temporary practice effects, and a transfer test shows whether the skill can be adapted.
Question 26Motor development, motor learning, and movement skill acquisition
A coach begins by giving feedback after every golf swing and then gradually reduces feedback to every third or fourth swing. Which principle best explains this strategy?
- the specificity hypothesis, in which practice must exactly match the competition environment
- the guidance hypothesis, in which faded feedback reduces dependency on external information Correct answer.
- the closed-loop hypothesis, in which feedback is unnecessary once a skill is programmed
- the massed practice hypothesis, in which rest intervals should be minimized
Explanation
The guidance hypothesis suggests that very frequent feedback can make learners dependent on external information and reduce their own error detection. Gradually fading feedback encourages learners to use intrinsic feedback and develop more durable performance.
Question 27Motor development, motor learning, and movement skill acquisition
Before a downhill ski run, an athlete mentally rehearses each gate, turn, and body position in sequence. Which statement best reflects the evidence on this kind of mental practice?
- it is effective only for strength gains and not for movement accuracy
- it can supplement physical practice, especially for cognitive and sequencing aspects Correct answer.
- it has no measurable effect on motor performance because no movement occurs
- it replaces the need for physical practice once the skill is learned
Explanation
Mental practice can support motor performance and learning when used alongside physical practice, particularly for tasks with strong cognitive, strategic, or sequencing demands. It does not replace physical practice or produce strength gains by itself.
Question 28Motor development, motor learning, and movement skill acquisition
In Schmidt's generalized motor program theory, which feature is best described as a parameter rather than an invariant characteristic?
- the order in which the movement components are sequenced
- the relative force pattern among the participating muscles
- the relative timing of the components of the movement
- the overall duration of the movement Correct answer.
Explanation
A generalized motor program has invariant features such as relative timing, relative force, and sequence order. Parameters are adjustable features that scale the program to a specific situation, including overall duration, overall force, and muscle selection.
Question 29Motor development, motor learning, and movement skill acquisition
During a rapid adolescent growth spurt, a previously coordinated student becomes temporarily clumsy and less accurate in ball skills. Which explanation is most consistent with motor development research?
- growth changes limb leverage and requires proprioceptive recalibration Correct answer.
- the student has permanently lost previously acquired motor programs
- clumsiness is primarily caused by a lack of motivation during puberty
- adolescents cannot learn new motor skills until growth is complete
Explanation
Rapid changes in limb length and body proportions alter leverage and the relationship between body segments, so previously calibrated proprioceptive control must be adjusted. This temporary mismatch can produce clumsiness during growth spurts without indicating permanent loss of skill.
Question 30Motor development, motor learning, and movement skill acquisition
A teacher introduces a javelin throw with the instruction 'reach up and scratch the sky, then pull the rope down' rather than listing joint-by-joint technical rules. This approach is most likely intended to promote which learning condition?
- implicit learning through an analogy that limits conscious rule use Correct answer.
- massed practice with minimal rest between attempts
- blocked practice with low contextual interference
- explicit rule learning with high conscious monitoring of each body segment
Explanation
Analogy instructions are often used to promote implicit motor learning by conveying the movement goal without generating many explicit technical rules. This can reduce conscious monitoring and may help performance remain stable under pressure.
Question 31Motor development, motor learning, and movement skill acquisition
A preschool teacher observes that infants typically lift the head before sitting with a straight trunk and sit before walking. Which directional trend in motor development does this sequence illustrate?
- Control of the head and neck precedes control of the lower limbs. Correct answer.
- Control of the legs precedes control of the trunk.
- Control of the fingers precedes control of the upper arm.
- Control of the trunk precedes control of the head and neck.
Explanation
The cephalocaudal trend refers to a head-to-tail direction of development: control of the head and neck emerges before control of the trunk and lower limbs. The proximodistal trend, by contrast, describes proximal-to-distal development within a limb. This question asks specifically about the head-to-lower-limb sequence.
Question 32Motor development, motor learning, and movement skill acquisition
After a badminton serve, a teacher tells a student, “Your shuttle landed outside the back boundary line.” This statement is best classified as which type of augmented feedback?
- Knowledge of results Correct answer.
- Knowledge of performance
- Knowledge of execution
- Intrinsic feedback
Explanation
Knowledge of results is augmented feedback about the outcome of a movement relative to the goal, such as whether the shuttle landed in or out. Knowledge of performance supplies information about the movement pattern itself. The teacher’s comment describes only the ball’s landing outcome.
Question 33Motor development, motor learning, and movement skill acquisition
Which of the following sport skills is best classified as a closed skill?
- Returning a tennis serve in a match
- Dribbling a basketball while guarded by a defender
- Performing a free throw in basketball Correct answer.
- Catching a fly ball in softball
Explanation
A closed skill is performed in a predictable, stable environment in which the performer controls the timing of the action. A free throw fits that description because the ball, target, and conditions remain essentially fixed. The other skills require adapting to a moving object or opponent.
Question 34Motor development, motor learning, and movement skill acquisition
In Gentile’s multidimensional classification system, a gymnastics vault performed in a fixed environment with no variation between trials is best described as which type of skill?
- Closed skill with intertrial variability
- Open skill with intertrial variability
- Closed skill with no intertrial variability Correct answer.
- Open skill with no intertrial variability
Explanation
Gentile’s taxonomy classifies skills by environmental context and action requirements. A fixed-environment vault with the same conditions on every trial is a closed skill and lacks intertrial variability. Intertrial variability would be present if the performer had to vary the movement from trial to trial.
Question 35Motor development, motor learning, and movement skill acquisition
A teacher modifies a striking task by using a larger, lighter paddle and a slower ball. In Newell’s constraints model, these modifications primarily represent which category of constraint?
- Individual constraints
- Task constraints Correct answer.
- Sociocultural constraints
- Environmental constraints
Explanation
In Newell’s model, task constraints include the goal, rules, and equipment of the activity. Changing to a larger, lighter paddle and a slower ball alters the task demands directly. Individual constraints reside in the learner, and environmental constraints are external physical or sociocultural conditions.
Question 36Motor development, motor learning, and movement skill acquisition
Two groups practice three badminton serves. Group A practices 30 trials of one serve, then 30 of the second, then 30 of the third. Group B alternates serves every trial. Which result would be most consistent with the contextual interference effect?
- Both groups perform identically during practice and on a delayed retention test.
- Group A performs better during practice and on a retention test.
- Group A performs better during practice, but Group B performs better on a delayed retention test. Correct answer.
- Group B performs better during practice and on a retention test.
Explanation
The contextual interference effect predicts that random or alternating practice often depresses performance during acquisition but enhances retention and transfer. Blocked practice usually yields stronger practice performance but weaker long-term learning. Group B’s alternating schedule therefore should show the classic practice-retention trade-off.
Question 37Motor development, motor learning, and movement skill acquisition
A tennis player who first learned a slice backhand has difficulty learning a topspin backhand because the two strokes require different swing paths and racket-face orientations. This difficulty is best explained by which concept?
- Bilateral transfer
- Retroactive facilitation
- Positive transfer
- Negative transfer Correct answer.
Explanation
Negative transfer occurs when prior learning interferes with the acquisition or performance of a new skill. A slice backhand and a topspin backhand require different swing paths and racket-face orientations, so the earlier pattern can disrupt the new one. Positive transfer would facilitate the new skill, and bilateral transfer concerns transfer between limbs.
Question 38Motor development, motor learning, and movement skill acquisition
A student practicing a tennis forehand now makes fewer errors, consistently contacts the ball in front, and can correct some of her own errors during practice. According to Fitts and Posner, which stage is she most likely in?
- Reflexive stage
- Cognitive stage
- Autonomous stage
- Associative stage Correct answer.
Explanation
In the associative stage, learners refine the movement pattern, reduce errors, and become more consistent while still monitoring performance. The cognitive stage is marked by large errors and heavy conscious problem-solving, and the autonomous stage is characterized by automatic, low-attention execution. The student’s improved consistency and self-correction fit the associative stage.
Question 39Motor development, motor learning, and movement skill acquisition
In Schmidt’s schema theory, which statement best distinguishes the recall schema from the recognition schema?
- The recall schema selects parameters, whereas the recognition schema evaluates response-produced feedback. Correct answer.
- Both schemas select the invariant features of a movement before execution.
- The recall schema operates only in closed skills, and the recognition schema operates only in open skills.
- The recognition schema selects parameters, whereas the recall schema evaluates response-produced feedback.
Explanation
In Schmidt’s schema theory, the recall schema is used to select and initiate the parameters for a movement, while the recognition schema is used to evaluate the sensory consequences against the expected outcome. The two schemas serve different functions in movement production and error detection. This distinction is central to schema-based explanations of motor learning.
Question 40Motor development, motor learning, and movement skill acquisition
A baseball batter must estimate the arrival time and location of a pitch to initiate a swing so the bat meets the ball. Which perceptual-motor process is most directly involved in this timing?
- Rhythmic awareness
- Coincidence-anticipation timing Correct answer.
- Spatial awareness
- Static balance control
Explanation
Coincidence-anticipation timing is the perceptual-motor ability to coordinate a movement with an externally moving object so that the two coincide in time and space. A batter must predict the pitch’s arrival and time the swing accordingly. Static balance, spatial awareness, and rhythm are related perceptual skills but do not capture this interception timing specifically.
Question 41Motor development, motor learning, and movement skill acquisition
Which category of fundamental movement skills is illustrated by running, hopping, and skipping?
- Axial skills
- Stability skills
- Manipulative skills
- Locomotor skills Correct answer.
Explanation
Locomotor skills transport the body from one place to another and include running, hopping, skipping, jumping, and galloping. Manipulative skills involve handling objects, stability skills involve maintaining balance, and axial skills are nonlocomotor movements such as bending or twisting.
Question 42Motor development, motor learning, and movement skill acquisition
A beginner learning a badminton overhead clear makes frequent errors, asks many questions about the sequence of steps, and cannot yet detect what went wrong. According to Fitts and Posner, this performer is most likely in which stage of learning?
- Cognitive stage Correct answer.
- Retention stage
- Associative stage
- Autonomous stage
Explanation
The cognitive stage is characterized by high error rates, verbal-cognitive activity, and limited error detection as the learner builds a basic movement plan. The associative stage shows refinement and fewer errors, while the autonomous stage is highly automatic and consistent.
Question 43Motor development, motor learning, and movement skill acquisition
A physical education teacher notes that young children gain control of the shoulder and upper arm before they can precisely control the wrist and fingers. This pattern best illustrates which developmental principle?
- Cephalocaudal principle
- Proximodistal principle Correct answer.
- Differentiation principle
- Reciprocal principle
Explanation
The proximodistal principle describes development proceeding from the center of the body outward, so proximal segments such as the trunk and shoulder gain control before distal segments such as the fingers. Cephalocaudal development proceeds head-to-tail, which is a different direction.
Question 44Motor development, motor learning, and movement skill acquisition
A teacher teaches a cartwheel by having students practice the lunge, then the hand placement, then the leg action before combining them into the full skill. Which task analysis best justifies this part-whole strategy?
- The task is low in complexity and low in organization.
- The task is low in complexity and high in organization.
- The task is high in complexity and low in organization. Correct answer.
- The task is high in organization and high in complexity.
Explanation
Part practice is most appropriate when a skill is high in complexity but low in organization, meaning it has many components that can be separated without destroying the overall timing. High organization means the parts interact tightly, making part practice less suitable.
Question 45Motor development, motor learning, and movement skill acquisition
A novice soccer player initially kicks with the hip and knee joints held nearly rigid, then gradually adds joint motion as skill improves. This progression is best explained by which motor learning concept?
- Bernstein's degrees of freedom Correct answer.
- Schmidt's generalized motor program
- Adams' closed-loop theory
- Gentile's multidimensional classification
Explanation
Bernstein proposed that beginners often freeze degrees of freedom to simplify control, then release and coordinate additional joint movements as skill develops. This freezing-to-releasing progression is a hallmark of the degrees-of-freedom concept.
Question 46Motor development, motor learning, and movement skill acquisition
A student's practice scores improve steadily, but one week later the student performs at baseline on a retention test. A classmate with similar practice scores performs much better on the same retention test. Which conclusion is most defensible?
- The retention test measures fitness rather than learning.
- The skill is a closed skill and should not be tested after a delay.
- Practice performance is not a dependable index of learning. Correct answer.
- The first student learned more but was less motivated during testing.
Explanation
Motor learning is inferred from relatively permanent changes measured by retention or transfer tests, not from temporary performance during practice. Similar practice scores can mask different amounts of learning, so retention performance is the stronger evidence.
Question 47Motor development, motor learning, and movement skill acquisition
A teacher wants students to transfer a basketball chest pass to a similar netball chest pass. Which practice condition best reflects the specificity of practice principle?
- Practice with a heavier medicine ball only, then switch to the game ball.
- Practice passes from varied distances, with defenders and pass choices resembling the netball context. Correct answer.
- Practice only one fixed distance with no defender and no variation in pass type.
- Practice only after watching a video of an expert netball player.
Explanation
The specificity of practice principle holds that learning transfers best when practice conditions resemble the conditions of the transfer task. Varying distance, opposition, and pass choice makes practice more similar to the netball context than a single fixed drill.
Question 48Motor development, motor learning, and movement skill acquisition
Before students practice a dance sequence, a teacher has them watch a proficient peer perform it correctly. Which explanation best accounts for the expected benefit of this modeling?
- The model directly reinforces the observers' correct responses.
- The model helps observers build a cognitive representation of the action. Correct answer.
- The model increases observers' arousal enough to replace practice.
- The model provides physical guidance through the sequence.
Explanation
Observational learning is thought to work by helping learners form a cognitive representation or reference of the movement that guides later attempts. The observer then uses that representation to organize and refine practice.
Question 49Motor development, motor learning, and movement skill acquisition
Learners who choose when to receive video feedback often show better retention than yoked learners who receive the same number of feedback presentations. Which explanation is most consistent with motor learning research?
- Self-controlled feedback promotes deeper processing and error detection. Correct answer.
- Yoked learners necessarily receive more feedback than self-controlled learners.
- Video feedback is beneficial only when it is delivered after every trial.
- Self-controlled learners spend more total time practicing the skill.
Explanation
Self-controlled practice is thought to enhance learning because learners actively monitor their performance, decide when information is needed, and process feedback more deeply. Yoked designs equalize feedback frequency, so the advantage is not explained by receiving more feedback.
Question 50Motor development, motor learning, and movement skill acquisition
An infant's walking pattern changes from a wide-based gait with high guard arms to a narrower, more efficient gait as strength and balance improve. In dynamical systems terms, which explanation is most appropriate?
- The infant has moved from random practice to blocked practice.
- A rate limiter such as strength or balance has changed, allowing a more advanced gait pattern. Correct answer.
- The gait change is due mainly to imitation of adult models.
- A generalized motor program has been replaced by a reflex.
Explanation
In dynamical systems theory, rate limiters are individual constraints that can hold back the emergence of a new movement pattern until they change. As strength and balance improve, the infant can abandon the wide, high-guard pattern for a more efficient gait.
