Question 1Foundations and Principles of Behavior Analysis

Which sequence represents the three-term contingency?

  1. Consequence – antecedent stimulus – behavior
  2. Antecedent stimulus – behavior – consequence Correct answer.
  3. Motivating operation – consequence – behavior
  4. Behavior – consequence – antecedent stimulus

Explanation

The three-term contingency describes the functional relation among an antecedent stimulus that sets the occasion for behavior, the behavior itself, and the consequence that follows it. Order matters: the antecedent precedes behavior, and the consequence follows it.

Question 2Foundations and Principles of Behavior Analysis

Which statement best captures the position of radical behaviorism?

  1. Behavior is best explained by underlying mental structures
  2. Private events are behavior subject to the same principles Correct answer.
  3. Only publicly observable actions can be studied scientifically
  4. Behavior is primarily the product of innate biological drives

Explanation

Radical behaviorism includes private events such as thoughts and feelings within the subject matter of behavior analysis and treats them as behavior governed by the same environmental relations as observable behavior. It does not reject private events, nor does it explain behavior by appeal to mental structures.

Question 3Foundations and Principles of Behavior Analysis

A student complains about an assignment, the teacher removes the assignment, and the student's complaining increases in the future. Removing the assignment is best described as:

  1. negative punishment
  2. negative reinforcement Correct answer.
  3. positive punishment
  4. positive reinforcement

Explanation

Negative reinforcement is the removal of a stimulus contingent on a response that increases the future frequency of that response. Here the assignment is removed and complaining increases, so the removal functions as negative reinforcement.

Question 4Foundations and Principles of Behavior Analysis

What makes a consequence a reinforcer?

  1. It is delivered immediately after the response
  2. It is pleasant or enjoyable for the learner
  3. It is something the learner says they prefer
  4. It increases the future frequency of the response Correct answer.

Explanation

Reinforcement is defined by its effect on behavior: a consequence is a reinforcer only if it increases the future frequency of the response it follows. Immediacy, preference, and subjective pleasantness may support effectiveness but are not the defining criterion.

Question 5Foundations and Principles of Behavior Analysis

In respondent conditioning, a neutral stimulus becomes a conditioned stimulus through:

  1. reinforcing responses that occur in its presence
  2. being presented after a response is emitted
  3. repeated pairing with an unconditioned stimulus Correct answer.
  4. extinguishing a previously learned operant

Explanation

Respondent conditioning occurs when a neutral stimulus is repeatedly paired with an unconditioned stimulus until it elicits a conditioned response on its own. The process is based on stimulus–stimulus pairing rather than on consequences of emitted behavior.

Question 6Foundations and Principles of Behavior Analysis

Reinforcing successively closer approximations of a target skill is called:

  1. chaining
  2. fading
  3. prompting
  4. shaping Correct answer.

Explanation

Shaping is differential reinforcement of successive approximations toward a terminal performance. Chaining assembles already-learned component responses into a sequence, and fading and prompting are antecedent manipulations.

Question 7Foundations and Principles of Behavior Analysis

Discontinuing the reinforcer that previously maintained a response is known as:

  1. habituation
  2. extinction Correct answer.
  3. satiation
  4. punishment

Explanation

Operant extinction is the withholding of the reinforcer that previously maintained a response, which produces a decrease in that response over time. It differs from punishment, which adds or removes a stimulus contingent on behavior.

Question 8Foundations and Principles of Behavior Analysis

The assumption that behavior occurs lawfully as a function of other events is:

  1. parsimony
  2. determinism Correct answer.
  3. selectionism
  4. pragmatism

Explanation

Determinism is the philosophical assumption that behavior is not random but occurs as a function of identifiable variables. Pragmatism, selectionism, and parsimony are separate assumptions that guide behavior-analytic interpretation.

Question 9Foundations and Principles of Behavior Analysis

Each time a student shouts out, a teacher removes one token from the student's card, and shouting decreases. This procedure is:

  1. positive punishment
  2. extinction
  3. negative reinforcement
  4. negative punishment Correct answer.

Explanation

Negative punishment occurs when a stimulus is removed contingent on behavior and the behavior decreases in the future. Removing tokens is response cost, a form of negative punishment.

Question 10Foundations and Principles of Behavior Analysis

A student has had no access to teacher attention all morning and begins working harder for brief praise. The deprivation is best described as:

  1. a discriminative stimulus
  2. a conditioned punisher
  3. a schedule effect
  4. an establishing operation Correct answer.

Explanation

An establishing operation is a motivating operation that increases the momentary effectiveness of a reinforcer and evokes the behavior that has produced it. Deprivation from attention increases the value of attention and strengthens attention-seeking behavior.

Question 11Foundations and Principles of Behavior Analysis

A child learns to say "car" for the family sedan and then says "car" for trucks and buses. This outcome is:

  1. stimulus overselectivity
  2. stimulus discrimination
  3. stimulus generalization Correct answer.
  4. response generalization

Explanation

Stimulus generalization occurs when a response taught in the presence of one stimulus occurs in the presence of similar stimuli. The behavior is the same; the range of evocative stimuli has widened.

Question 12Foundations and Principles of Behavior Analysis

A learner is reinforced for saying "cat" in the presence of cats and not reinforced for saying it to dogs; eventually "cat" occurs only with cats. This outcome is:

  1. shaping
  2. generalization
  3. extinction
  4. discrimination Correct answer.

Explanation

Stimulus discrimination develops when responding is reinforced in the presence of one stimulus and extinguished in the presence of others, producing differential responding. The stimulus correlated with reinforcement becomes a discriminative stimulus.

Question 13Foundations and Principles of Behavior Analysis

A schedule that delivers reinforcement after every fifth correct response is:

  1. variable interval 5
  2. variable ratio 5
  3. fixed ratio 5 Correct answer.
  4. fixed interval 5

Explanation

Ratio schedules require a specified number of responses, and a fixed ratio delivers reinforcement after a constant count. With a requirement of five responses, the schedule is fixed ratio 5.

Question 14Foundations and Principles of Behavior Analysis

Which schedule typically produces a moderate, steady response rate with few post-reinforcement pauses?

  1. fixed interval
  2. variable interval Correct answer.
  3. fixed ratio
  4. continuous reinforcement

Explanation

Variable interval schedules arrange reinforcement for the first response after unpredictable time periods, which generates a moderate, stable rate with little pausing. Fixed schedules tend to produce distinct post-reinforcement pauses.

Question 15Foundations and Principles of Behavior Analysis

A token that has been paired with access to preferred items and praise begins to increase the behavior it follows. The token now functions as:

  1. a punisher
  2. an unconditioned reinforcer
  3. a conditioned reinforcer Correct answer.
  4. a discriminative stimulus

Explanation

A stimulus that acquires reinforcing effectiveness through pairing with established reinforcers is a conditioned reinforcer. The token's effect depends on its learned relation to backup reinforcers.

Question 16Foundations and Principles of Behavior Analysis

Teaching a multi-step routine by training the last step first and adding earlier steps as each is mastered is:

  1. backward chaining Correct answer.
  2. task analysis
  3. total task presentation
  4. forward chaining

Explanation

Backward chaining teaches the terminal step of a task analysis first and then adds preceding steps in reverse order. This approach lets the learner contact the natural terminal reinforcer early in instruction.

Question 17Foundations and Principles of Behavior Analysis

In the dimensions of applied behavior analysis, "technological" means the procedures are:

  1. delivered through computer-based systems
  2. analyzed for their underlying mechanisms
  3. described precisely enough to be replicated Correct answer.
  4. focused on socially important goals

Explanation

The technological dimension requires that procedures be identified and described clearly enough that a reader could replicate them. It concerns the completeness of the written description, not the medium of delivery.

Question 18Foundations and Principles of Behavior Analysis

Reaching, pointing, and grunting that all produce the same outcome for a learner constitute a:

  1. discriminative stimulus
  2. stimulus class
  3. response class Correct answer.
  4. response chain

Explanation

A response class is a set of responses that differ in topography but share a common effect on the environment. Because all three forms produce the same outcome, they belong to one response class.

Question 19Foundations and Principles of Behavior Analysis

After a response has been extinguished, it briefly reappears following a break from the session. This is:

  1. spontaneous recovery Correct answer.
  2. resurgence
  3. renewal
  4. response induction

Explanation

Spontaneous recovery is the temporary recurrence of an extinguished response after a period of time has passed without further extinction trials. The response typically returns at a lower strength and declines again with continued extinction.

Question 20Foundations and Principles of Behavior Analysis

A learner says "juice" because they are thirsty and then receives juice. This verbal operant is a:

  1. echoic
  2. mand Correct answer.
  3. intraverbal
  4. tact

Explanation

A mand is a verbal response reinforced by a characteristic consequence and under the control of a motivating operation such as thirst. Asking for juice when thirsty is the textbook mand relation.

Question 21Foundations and Principles of Behavior Analysis

A child has been deprived of attention. Whining increases in the presence of one particular teacher, while it stays low with other adults present. The teacher's presence functions primarily as:

  1. an establishing operation
  2. a discriminative stimulus Correct answer.
  3. a conditioned punisher
  4. an abolishing operation

Explanation

Differential responding across adults shows that the teacher's presence sets the occasion for reinforcement; that is discriminative control. The deprivation itself is the motivating operation, but the teacher's presence is the antecedent that signals availability.

Question 22Foundations and Principles of Behavior Analysis

A basketball player wears the same socks during several good games and keeps wearing them afterward. The persistent sock wearing is best attributed to:

  1. an unconditioned reinforcement contingency
  2. a rule-governed contingency
  3. a discriminative stimulus effect
  4. an accidental reinforcement contingency Correct answer.

Explanation

When a consequence follows a behavior by coincidence rather than because of a programmed relation, the resulting strengthening is an accidental, sometimes called superstitious, contingency. The socks acquired reinforcing properties only through temporal correlation with good outcomes.

Question 23Foundations and Principles of Behavior Analysis

After a large meal, a learner works much less for food than usual. The meal is best described as a motivating operation whose effect is:

  1. abolishing, because it decreases the value of food as a reinforcer Correct answer.
  2. reinforcing, because it strengthens eating behavior
  3. evocative, because it signals that food is available
  4. value-altering only, with no effect on behavior

Explanation

Consuming a large meal is an abolishing operation: it decreases the reinforcing effectiveness of food and, in turn, abates behavior that has produced food. Motivating operations have both value-altering and behavior-altering effects.

Question 24Foundations and Principles of Behavior Analysis

Behavior analysts explain novel behavior through selection by consequences operating at which three levels?

  1. classical, operant, and respondent conditioning
  2. phylogeny, ontogeny, and culture Correct answer.
  3. reinforcement, punishment, and extinction
  4. sensation, perception, and cognition

Explanation

Selectionism holds that novel behavior arises through selection by consequences at three levels: phylogenic selection of unlearned repertoires, ontogenic selection of operant repertoires, and cultural selection of practices. Conditioning procedures and consequence types are processes, not levels of selection.

Question 25Foundations and Principles of Behavior Analysis

A learner taught to greet familiar adults with a wave begins also bowing and saying "hello" to those adults. This outcome is best described as:

  1. response generalization Correct answer.
  2. stimulus discrimination
  3. response chaining
  4. stimulus generalization

Explanation

Response generalization occurs when a change in one response is accompanied by changes in other responses that serve the same function. The antecedent (familiar adults) is unchanged while new response forms appear.

Question 26Foundations and Principles of Behavior Analysis

A behavior analyst must choose between two explanations for a learner's behavior. One requires three inferred mental processes; the other requires a single observable environmental event. The principle of parsimony directs the analyst to:

  1. select the account that appears most often in published studies
  2. adopt the simpler explanation that requires the fewest assumptions Correct answer.
  3. reject both accounts until physiological data can be collected
  4. prefer the explanation that invokes the most internal mental states

Explanation

Parsimony is the rule that the simplest adequate account of a phenomenon is preferred over accounts requiring extra assumptions. Simplicity is judged by the number of assumptions and inferred entities an explanation needs, not by its popularity. The account resting on one observable environmental event is therefore preferred.

Question 27Foundations and Principles of Behavior Analysis

A puff of air to the eye makes a learner blink before any conditioning procedure has been conducted. In respondent conditioning terms, the puff of air is:

  1. an establishing operation
  2. a conditioned response
  3. an unconditioned stimulus Correct answer.
  4. a conditioned stimulus

Explanation

An unconditioned stimulus is an event that elicits a response without any prior learning history. Because the air puff produces blinking before conditioning, it fills the unconditioned stimulus role and the blink is the unconditioned response. Conditioned terms apply only after a neutral event has been paired with such a stimulus.

Question 28Foundations and Principles of Behavior Analysis

In the three-term contingency, the antecedent stimulus that signals that reinforcement is currently available for a particular response is called:

  1. a motivating operation
  2. a conditioned reinforcer
  3. a discriminative stimulus Correct answer.
  4. an S-delta

Explanation

A discriminative stimulus is present when a response has been reinforced in its presence and its presence increases the likelihood of that response. It signals the availability of reinforcement rather than altering the value of the consequence. This differs from stimuli correlated with extinction, which are S-deltas.

Question 29Foundations and Principles of Behavior Analysis

A student teases a peer, and the teacher immediately reprimands the student. Over the next several days, teasing occurs less often. This procedure is best classified as:

  1. negative punishment
  2. extinction
  3. negative reinforcement
  4. positive punishment Correct answer.

Explanation

Positive punishment is the contingent addition of a stimulus following a response that decreases the future frequency of that response. Here a reprimand is added immediately after teasing, and teasing declines. The defining features are the addition of a consequence and the resulting decrease in behavior.

Question 30Foundations and Principles of Behavior Analysis

Whenever a difficult worksheet is placed on a student's desk, the student tears it up and is sent to the hallway, where work stops. Tearing up worksheets has increased over time. The contingency maintaining this behavior is:

  1. automatic reinforcement unrelated to the classroom contingencies
  2. negative reinforcement in the form of escape from task demands Correct answer.
  3. positive punishment produced by removal of the worksheet
  4. positive reinforcement in the form of access to hallway activities

Explanation

Negative reinforcement occurs when a response produces the removal or postponement of a stimulus and the response increases as a result. Tearing the worksheet terminates task demands, and the behavior has strengthened, so escape is the maintaining contingency. The critical feature is the removal of an ongoing aversive condition.

Question 31Foundations and Principles of Behavior Analysis

After reinforcement for a previously reinforced response is discontinued, a practitioner should anticipate a temporary increase in the frequency, magnitude, or variability of the response. This phenomenon is:

  1. response induction
  2. habituation
  3. an extinction burst Correct answer.
  4. spontaneous recovery

Explanation

An extinction burst is the brief escalation in responding that often occurs at the start of extinction before the response declines. Practitioners plan for it by using safety procedures and avoiding accidental reinforcement of the intensified response. It is distinguished from other extinction-related effects by its timing and its direction of change.

Question 32Foundations and Principles of Behavior Analysis

A student currently requests help about 20 times per hour. The teacher delivers a reinforcer at the end of any hour in which the student requested help three times or fewer. This arrangement is:

  1. differential reinforcement of other behavior (DRO)
  2. differential reinforcement of low rates (DRL) Correct answer.
  3. noncontingent reinforcement (NCR)
  4. differential reinforcement of alternative behavior (DRA)

Explanation

Differential reinforcement of low rates delivers reinforcement when a response occurs at or below a specified criterion, so it is used to reduce rather than eliminate a behavior. Here the criterion of three or fewer requests per hour defines the DRL arrangement. The behavior is still permitted, which distinguishes DRL from procedures that reinforce its absence.

Question 33Foundations and Principles of Behavior Analysis

A learner hears the question "What did you do at recess?" and answers "played tag," even though no tag equipment is present and the answer was not echoed from the question. This response is a:

  1. mand
  2. echoic
  3. intraverbal Correct answer.
  4. tact

Explanation

An intraverbal is a verbal response occasioned by another person's verbal behavior and maintained by generalized conditioned reinforcement, without a point-to-point correspondence to the antecedent. Answering a question with related content fits this definition. The absence of the relevant object rules out a tact.

Question 34Foundations and Principles of Behavior Analysis

The dimension of applied behavior analysis requiring that behavior change persists over time, appears in settings other than the training setting, and spreads to related behaviors is:

  1. generality Correct answer.
  2. analytic
  3. effective
  4. applied

Explanation

Generality refers to behavior change that endures, transfers across settings and people, and extends to untrained responses. It is assessed after the programmed contingencies are withdrawn or applied elsewhere. The other dimensions describe the social importance of the target, the demonstration of control, and the practical magnitude of change.

Question 35Foundations and Principles of Behavior Analysis

A teacher allows a student who has just completed math problems to spend five minutes on a highly preferred computer activity. Using the opportunity to engage in a high-probability activity to reinforce a low-probability activity illustrates:

  1. the Premack principle Correct answer.
  2. stimulus equivalence
  3. response cost
  4. the matching law

Explanation

The Premack principle states that a higher-probability behavior can reinforce a lower-probability behavior when access to the former is made contingent on the latter. Computer time is the high-probability activity and math completion is the low-probability activity. No stimulus is removed and no derived relations are involved.

Question 36Foundations and Principles of Behavior Analysis

A learner who wants to listen to music discovers that the headphones are missing and begins searching drawers for them. In this example, the headphones function as:

  1. an unconditioned motivating operation
  2. a transitive conditioned motivating operation Correct answer.
  3. a conditioned punisher
  4. a reflexive conditioned motivating operation

Explanation

A transitive conditioned motivating operation is a stimulus that acquires value through its relation to another reinforcer and then makes other stimuli effective. The missing headphones, paired with the reinforcing music, establish the drawer as a discriminative stimulus and evoke searching. This value-altering and behavior-evoking effect is the defining feature.

Question 37Foundations and Principles of Behavior Analysis

A consequence follows a response within milliseconds every time it occurs, but the same consequence is delivered on the same schedule whether or not the response happened. This relation between response and consequence is best described as:

  1. both contingent and contiguous
  2. neither contiguous nor contingent
  3. contingent but not contiguous
  4. contiguous but not contingent Correct answer.

Explanation

Contiguity refers to temporal closeness between events, while contingency refers to a dependency in which the consequence occurs only if the response occurs. A consequence that closely follows every response but would have occurred anyway is temporally close without being dependent on behavior. Reinforcement requires the dependency, not just the timing.

Question 38Foundations and Principles of Behavior Analysis

Hand-raising occurs at a high rate during math, when teacher praise is frequent, and at a moderate rate during reading, when praise is also frequent. When praise during math is reduced while reading praise stays unchanged, hand-raising in math decreases and hand-raising in reading increases. This pattern is:

  1. response generalization
  2. adjunctive behavior
  3. behavioral contrast Correct answer.
  4. behavioral momentum

Explanation

Behavioral contrast is a change in an unchanged component of a multiple schedule that occurs in the direction opposite to the change in the manipulated component. Here the reduction of praise in math produced a decrease there and an increase in the unchanged reading component. The opposite-direction shift in the unaltered setting is the defining feature.

Question 39Foundations and Principles of Behavior Analysis

When a motivating operation is added to the three-term contingency, the resulting four-term contingency is characterized by the motivating operation:

  1. guaranteeing that the response will occur even when no reinforcement is programmed for it
  2. serving as the consequence that follows the response
  3. substituting for the discriminative stimulus in the chain
  4. altering the effectiveness of the consequence and the momentary value of related stimuli Correct answer.

Explanation

A motivating operation has two defining effects: it alters the current effectiveness of a consequence as reinforcement or punishment, and it alters the momentary frequency of behavior related to that consequence. In a four-term contingency it is represented alongside the discriminative stimulus, response, and consequence. It changes the value of events without being the consequence itself.

Question 40Foundations and Principles of Behavior Analysis

On the first day of a new job, an employee clocks in before starting work after the supervisor says, "Clock in before you begin." The employee has never been reinforced for clocking in. This behavior is best described as:

  1. rule-governed behavior Correct answer.
  2. contingency-shaped behavior
  3. adjunctive behavior
  4. respondent behavior

Explanation

Rule-governed behavior is controlled by a verbal description of a contingency rather than by direct exposure to that contingency. The instruction specifies the relation between clocking in and its consequences, and the employee complies on the first exposure. Contingency-shaped behavior, by contrast, develops through direct reinforcement of the response.

Question 41Behavior Assessment and Measurement

A behavior analyst writes: 'Aggression is any instance of hitting another person with an open hand or closed fist from a distance of at least one foot.' This statement is best described as:

  1. a summary label
  2. a functional hypothesis
  3. a social validity rating
  4. an operational definition Correct answer.

Explanation

An operational definition describes behavior in observable, measurable terms and specifies boundaries for when an instance counts. This statement defines the behavior and its measurable limits rather than explaining its cause or judging its acceptability.

Question 42Behavior Assessment and Measurement

During a 20-minute lesson, a teacher wants to count how many times a student leaves their seat. Which measurement procedure is most appropriate?

  1. whole-interval recording
  2. momentary time sampling
  3. event recording Correct answer.
  4. latency recording

Explanation

Event recording is used to count discrete instances of a behavior as they occur. Leaving the seat is a discrete response that can be tallied each time it happens during the lesson.

Question 43Behavior Assessment and Measurement

After class, a teacher scores the number of correctly solved problems on worksheets students submitted. This measurement is best described as:

  1. partial-interval recording
  2. permanent product measurement Correct answer.
  3. direct observation of behavior
  4. trial-by-trial IOA

Explanation

Permanent product measurement uses the tangible outcomes or remains of behavior rather than observing the behavior as it occurs. The completed worksheet is a product that can be scored after the fact.

Question 44Behavior Assessment and Measurement

A behavior analyst starts a stopwatch when crying begins and stops it when crying ends. This measure is:

  1. latency
  2. duration Correct answer.
  3. interresponse time
  4. frequency

Explanation

Duration measures the amount of time a behavior lasts from onset to offset. The stopwatch records the length of each crying episode.

Question 45Behavior Assessment and Measurement

The time from the presentation of an instruction to the start of the requested response is called:

  1. rate
  2. duration
  3. interresponse time
  4. latency Correct answer.

Explanation

Latency is the elapsed time between a specified stimulus and the initiation of a response. The interval from instruction to response onset is a classic latency measure.

Question 46Behavior Assessment and Measurement

In whole-interval recording, behavior is scored as occurring only when it:

  1. occurs at any point during the interval
  2. occurs at the final moment of the interval
  3. occurs throughout the entire interval Correct answer.
  4. occurs more than once in the interval

Explanation

Whole-interval recording requires the behavior to be present for the entire interval before the interval is scored. This method tends to underestimate behavior because brief or intermittent occurrences are not counted.

Question 47Behavior Assessment and Measurement

Partial-interval recording is most likely to:

  1. overestimate the duration of behavior Correct answer.
  2. underestimate the duration of behavior
  3. produce an exact count of responses
  4. eliminate observer reactivity

Explanation

Partial-interval recording scores an interval if the behavior occurs at any time within it, even briefly. This can inflate estimates of duration or occurrence relative to continuous measurement.

Question 48Behavior Assessment and Measurement

On a single-case graph, the phase before an intervention is introduced is called the:

  1. treatment phase
  2. generalization phase
  3. maintenance phase
  4. baseline phase Correct answer.

Explanation

The baseline phase provides the comparison data collected before an intervention is implemented. It establishes the pre-intervention pattern of behavior against which treatment effects are evaluated.

Question 49Behavior Assessment and Measurement

Two observers record 30 and 27 responses in the same session. Using total count IOA, what is the IOA percentage?

  1. 85%
  2. 95%
  3. 90% Correct answer.
  4. 80%

Explanation

Total count IOA is calculated by dividing the smaller count by the larger count and multiplying by 100. Here, 27 divided by 30 equals 0.90, or 90%.

Question 50Behavior Assessment and Measurement

Two observers independently score 20 discrete trials and agree on 18. What is trial-by-trial IOA?

  1. 95%
  2. 80%
  3. 90% Correct answer.
  4. 85%

Explanation

Trial-by-trial IOA is the number of agreements divided by the total number of trials, multiplied by 100. Here, 18 divided by 20 equals 0.90, or 90%.
