Question 1Human Growth and Development

According to Piaget, a toddler who searches for a ball after it rolls behind a sofa but stops searching once it is fully hidden under a blanket is most likely in which stage?

  1. Formal operational stage
  2. Sensorimotor stage Correct answer.
  3. Preoperational stage
  4. Concrete operational stage

Explanation

The sensorimotor stage spans roughly birth to age two, and its defining achievement is object permanence, which emerges gradually near the end of the period. A child who searches only for partially visible objects but gives up on fully hidden ones is showing the incomplete permanence typical of this stage.

Question 2Human Growth and Development

A researcher shows an infant the same picture repeatedly until looking time declines, then presents a new picture and observes renewed looking. This procedure is designed to assess which capacity?

  1. Habituation and dishabituation as evidence of discrimination Correct answer.
  2. Conservation of number
  3. Stranger anxiety
  4. Scaffolding

Explanation

Habituation is the decline in response to a repeated stimulus, and dishabituation is the recovery of attention when a novel stimulus appears. Renewed looking at the new picture indicates the infant detected the difference, so the method indexes discrimination and memory in preverbal infants.

Question 3Human Growth and Development

A fetus's heart rate briefly accelerates after a loud sound is played near the mother's abdomen. This response is best described as evidence of which prenatal capacity?

  1. Fetal conservation
  2. Fetal visual acuity
  3. Fetal language production
  4. Fetal hearing and responsiveness to auditory stimulation Correct answer.

Explanation

The auditory system becomes functional in the later prenatal period, and researchers use heart-rate change to index fetal response to sound. An acceleration following a loud noise indicates that the fetus detected the stimulus, demonstrating functional hearing before birth.

Question 4Human Growth and Development

Which pattern of attachment is most associated in Ainsworth's strange situation with a child who shows little distress at separation and avoids or ignores the caregiver on reunion?

  1. Insecure-resistant attachment
  2. Secure attachment
  3. Disorganized attachment
  4. Insecure-avoidant attachment Correct answer.

Explanation

Insecure-avoidant infants show minimal separation distress and actively avoid or ignore the caregiver when reunited, reflecting a strategy of suppressing attachment needs. Secure infants seek contact and are readily comforted, which distinguishes them clearly from the avoidant pattern.

Question 5Human Growth and Development

A parent gradually reduces the amount of help given as a child learns to tie shoes, offering less support as the child succeeds. This practice best illustrates which concept?

  1. Reciprocal determinism
  2. Assimilation
  3. Conservation
  4. Scaffolding within the zone of proximal development Correct answer.

Explanation

Vygotsky described the zone of proximal development as the range of tasks a learner can do with assistance but not yet alone. Scaffolding is the temporary, adjustable support that adults provide within that zone and withdraw as competence grows.

Question 6Human Growth and Development

A child watches an older sibling receive praise for sharing toys and then begins sharing more often. This change is best explained by which process?

  1. Vicarious reinforcement through observational learning Correct answer.
  2. Habituation
  3. Preoperational egocentrism
  4. Classical conditioning of a reflex

Explanation

Bandura's social learning theory holds that children learn by observing models and the consequences those models receive. Seeing a sibling reinforced for sharing raises the likelihood the observer will imitate the behavior, which is vicarious reinforcement.

Question 7Human Growth and Development

A 15-month-old says 'milk' while pointing at the refrigerator and later uses 'milk' for juice as well. The second behavior illustrates which phenomenon?

  1. Underextension
  2. Phonological regression
  3. Telegraphic speech
  4. Overextension Correct answer.

Explanation

Overextension occurs when a child applies a word too broadly, as when 'milk' is used for other drinks. Underextension is the opposite error, in which a word is applied too narrowly, so the two are readily distinguished.

Question 8Human Growth and Development

A preschooler insists that a tall narrow glass holds more juice than a short wide glass, even after seeing the same amount poured from one to the other. This response reflects difficulty with which concept?

  1. Seriation
  2. Conservation Correct answer.
  3. Object permanence
  4. Abstract reasoning

Explanation

Conservation is the understanding that quantity remains the same when only the appearance changes, and it is typically achieved in the concrete operational stage. The child centers on the height dimension and ignores width, producing the classic nonconserving judgment.

Question 9Human Growth and Development

Kohlberg classified moral reasoning at the conventional level as being driven primarily by which consideration?

  1. Universal ethical principles of justice
  2. Biological temperament
  3. Upholding social expectations, laws, and approval of others Correct answer.
  4. Avoiding punishment and gaining rewards

Explanation

At the conventional level, individuals judge right and wrong by reference to social norms, the expectations of family and community, and maintaining the social order. Preconventional reasoning is self-interested, while postconventional reasoning appeals to abstract principles.

Question 10Human Growth and Development

Erikson's psychosocial stage of industry versus inferiority is most closely tied to which developmental period?

  1. Infancy
  2. Middle childhood Correct answer.
  3. Early childhood
  4. Late adulthood

Explanation

Industry versus inferiority corresponds roughly to the elementary school years, when children seek to master tasks valued by peers and adults. Success builds a sense of competence, while repeated failure or criticism fosters inferiority.

Question 11Human Growth and Development

A 10-year-old whose body mass index is at the 97th percentile for age and sex would most accurately be classified as which of the following?

  1. Overweight
  2. Healthy weight
  3. Underweight
  4. Obese Correct answer.

Explanation

Pediatric weight status is defined by age- and sex-specific BMI percentiles: obesity is at or above the 95th percentile, overweight is from the 85th to below the 95th. A value at the 97th percentile therefore falls in the obese category.

Question 12Human Growth and Development

During puberty, the sequence of physical changes in girls is best described by which statement?

  1. Breast budding typically precedes menarche by roughly two years Correct answer.
  2. Pubic hair appears only after menarche
  3. Height growth is completed before breast budding
  4. Menarche always occurs before any breast development

Explanation

In girls, the pubertal growth spurt and breast development usually begin well before menarche, with menarche occurring late in the sequence. The typical interval between breast budding and first menstruation is about two years, although individual variation is considerable.

Question 13Human Growth and Development

A young adult who has recently finished school is actively exploring career options and ideological commitments before settling on lasting choices. In Marcia's framework, this status is called:

  1. Identity achievement
  2. Identity diffusion
  3. Identity moratorium Correct answer.
  4. Identity foreclosure

Explanation

Marcia described identity statuses based on the presence of exploration and commitment. Moratorium is active exploration without a firm commitment yet, whereas achievement combines exploration with commitment.

Question 14Human Growth and Development

Research on crystallized and fluid intelligence across adulthood generally finds which pattern?

  1. Crystallized intelligence declines first while fluid intelligence rises
  2. Fluid intelligence tends to decline earlier while crystallized intelligence remains stable or grows Correct answer.
  3. Neither shows any age-related change
  4. Both decline steadily from early adulthood

Explanation

Fluid abilities such as processing speed and novel problem solving show earlier average declines, while crystallized abilities such as vocabulary and accumulated knowledge often hold steady or increase into middle age. This divergence is a central finding in life-span intelligence research.

Question 15Human Growth and Development

A person who scores high on a test of vocabulary and general knowledge but lower on a timed test of novel puzzle solving is showing a profile most consistent with which distinction?

  1. Concrete versus formal operations
  2. Crystallized versus fluid intelligence Correct answer.
  3. Secure versus avoidant attachment
  4. Assimilation versus accommodation

Explanation

Crystallized intelligence reflects accumulated knowledge and experience, while fluid intelligence reflects reasoning with novel material under speed demands. The described profile shows strength in the crystallized domain and relative weakness in the fluid domain.

Question 16Human Growth and Development

Which statement best describes the typical age trend in the ability to regulate negative emotion from early childhood to adolescence?

  1. It remains unchanged across childhood
  2. It generally improves with maturation and prefrontal development Correct answer.
  3. It declines sharply during middle childhood
  4. It is fully mature at birth

Explanation

Emotion regulation improves across childhood as prefrontal circuitry matures and children acquire strategies such as reappraisal and distraction. Although adolescence brings heightened emotional reactivity, overall regulatory capacity continues to develop.

Question 17Human Growth and Development

A parent uses a firm but reasoning-oriented response to a child's misbehavior, explaining why the behavior was wrong while maintaining clear expectations. This parenting style is best labeled:

  1. Authoritative Correct answer.
  2. Authoritarian
  3. Permissive
  4. Uninvolved

Explanation

Authoritative parenting combines high warmth with high, clearly communicated expectations and explanations for rules. This style is consistently linked with better child adjustment than the other three patterns.

Question 18Human Growth and Development

A child raised in a bilingual home mixes words from both languages in a single sentence at age three. This pattern is best interpreted as:

  1. A normal feature of bilingual language development Correct answer.
  2. A sign of cognitive deficit
  3. Evidence of a language disorder requiring immediate intervention
  4. Proof that the child cannot distinguish the languages

Explanation

Code-mixing is common and developmentally normal in children learning two languages simultaneously, especially when both languages are still developing. It does not by itself indicate disorder, and bilingual children typically learn to separate languages by context.

Question 19Human Growth and Development

Which of the following best characterizes the concept of a critical period in development?

  1. A limited window during which certain experiences must occur for typical development Correct answer.
  2. A stage defined solely by chronological age
  3. A period of rapid physical growth only
  4. Any time in life when learning is possible

Explanation

A critical period is a bounded developmental window during which specific experiences are necessary for a capacity to develop normally, such as early visual input or first-language exposure. After the window closes, the capacity is difficult or impossible to acquire fully.

Question 20Human Growth and Development

A researcher finds that children who eat breakfast regularly also perform better on school tests. Which conclusion is most warranted from this correlational finding alone?

  1. Eating breakfast causes higher test performance
  2. The finding must be due to random error
  3. Test performance causes children to eat breakfast
  4. Breakfast and test performance are associated, but causality cannot be established from this design Correct answer.

Explanation

Correlational designs establish association but cannot rule out third variables such as family income or general health habits. Causal claims require experimental or stronger quasi-experimental designs that control for confounds.

Question 21Human Growth and Development

According to Baumrind's framework, which parenting dimension primarily distinguishes authoritative from authoritarian parenting?

  1. The child's birth order
  2. The family's socioeconomic status
  3. The level of warmth and responsiveness shown to the child Correct answer.
  4. The number of children in the family

Explanation

Both authoritative and authoritarian parents set firm expectations, but authoritative parents are warm, responsive, and explain rules. Authoritarian parents are low in warmth and emphasize obedience, so warmth and responsiveness are the key distinguishing dimension.

Question 22Human Growth and Development

A memory researcher asks older adults to recall a list of words and finds they perform worse than younger adults on free recall but similarly on recognition. Which explanation is most consistent with this pattern?

  1. Older adults have superior working memory
  2. Older adults cannot encode any new information
  3. Older adults show no age-related memory change
  4. Older adults have greater difficulty with effortful retrieval than with storage Correct answer.

Explanation

Preserved recognition alongside impaired free recall suggests that information is stored but that effortful, self-initiated retrieval is more taxing with age. This pattern supports a retrieval-deficit interpretation rather than a pure encoding failure.

Question 23Human Growth and Development

Kubler-Ross's stage model of dying has been criticized primarily because:

  1. It applies only to children
  2. It is based entirely on laboratory experiments
  3. It denies that any emotional response to dying occurs
  4. It describes stages as rigid and sequential, but dying experiences vary widely Correct answer.

Explanation

The stage model is often presented as a fixed sequence, yet empirical work shows that people move among responses such as denial, anger, and acceptance in varied orders and may never experience some of them. Critics therefore emphasize individual variability and the non-linear nature of coping.

Question 24Human Growth and Development

Which statement accurately describes the direction of the pubertal growth spurt in boys compared with girls?

  1. Boys begin their growth spurt about two years earlier than girls
  2. Boys and girls begin at exactly the same age
  3. Boys never experience a growth spurt
  4. Boys typically begin their growth spurt about two years later than girls Correct answer.

Explanation

On average, girls enter the pubertal growth spurt around age ten to eleven, while boys begin roughly two years later. This timing difference explains why girls are often temporarily taller than boys during early adolescence.

Question 25Human Growth and Development

A child who can sort blocks by color and then re-sort the same blocks by shape is demonstrating which concrete operational ability?

  1. Egocentric speech
  2. Object permanence
  3. Classification Correct answer.
  4. Conservation of mass

Explanation

Classification is the concrete operational ability to group objects according to shared attributes and to shift the basis of grouping. Re-sorting the same set by a different attribute shows flexible classification, which preoperational children typically find difficult.

Question 26Human Growth and Development

An infant who smiles at a stranger but clings to the caregiver and cries when the caregiver leaves is displaying behavior most consistent with which milestone?

  1. Social referencing
  2. Stranger wariness and separation protest Correct answer.
  3. Parallel play
  4. Reciprocal scaffolding

Explanation

Stranger wariness and separation protest emerge in the second half of the first year as infants form specific attachments and can distinguish familiar from unfamiliar people. Clinging and crying at separation are the defining signs.

Question 27Human Growth and Development

A 4-year-old says 'I goed to the store' instead of 'I went.' This error most directly demonstrates which phenomenon?

  1. Underextension of word meaning
  2. Telegraphic speech
  3. Phonological simplification
  4. Overregularization of a grammatical rule Correct answer.

Explanation

The child has extracted the regular past-tense rule and applies it to an irregular verb, producing an overregularization error. Such errors show rule learning rather than simple imitation.

Question 28Human Growth and Development

Which statement best describes the normative pattern of physical growth in the first year of life?

  1. Head circumference grows more slowly than chest circumference throughout infancy
  2. Birth weight typically doubles by about 5 months and triples by about 12 months Correct answer.
  3. Length increases by roughly 50 percent in the first month alone
  4. Birth weight typically triples by 3 months and quadruples by 12 months

Explanation

Standard growth references show birth weight doubling near 5 months and tripling near the first birthday. This cephalocaudal pattern is a widely taught normative benchmark in developmental texts.

Question 29Human Growth and Development

A school-age child can tell that a ball of clay reshaped into a long thin snake still contains the same amount of clay. According to Piaget, this ability indicates the acquisition of which concept?

  1. Centration
  2. Animism
  3. Conservation Correct answer.
  4. Egocentrism

Explanation

Conservation is the understanding that quantity is unchanged despite changes in appearance, and it typically appears in the concrete operational stage. Recognizing the clay's amount as constant across reshaping is the classic demonstration.

Question 30Human Growth and Development

A child who can classify a set of animals by habitat and then reclassify the same animals by diet is demonstrating which concrete operation?

  1. Object permanence
  2. Class inclusion and multiple classification Correct answer.
  3. Transductive reasoning
  4. Hypothetical-deductive reasoning

Explanation

Multiple classification is the concrete operational ability to group the same objects along more than one dimension, and class inclusion involves relating a subclass to its superordinate class. Re-sorting the same set by a new rule reflects this flexible grouping.

Question 31Human Growth and Development

Which statement best captures Vygotsky's zone of proximal development?

  1. The gap between a child's mental age and chronological age on a standardized test
  2. The range of tasks a child can accomplish with guidance but not yet alone Correct answer.
  3. The set of skills a child has already mastered independently
  4. The age range during which a skill must be acquired or never will be

Explanation

Vygotsky defined the zone of proximal development as the distance between what a learner can do unaided and what the learner can do with assistance from a more capable partner. Instruction is most effective when aimed at this zone.

Question 32Human Growth and Development

A researcher observes that children who are read to daily at age four score higher on a kindergarten vocabulary test. Which statement about this finding is most defensible?

  1. The association is correlational and may reflect other family factors such as income or parental education Correct answer.
  2. The finding shows that vocabulary is entirely determined by heredity
  3. The finding proves that daily reading causes higher vocabulary
  4. The finding is invalid because vocabulary cannot be measured in kindergarten

Explanation

Observational designs without random assignment cannot establish causation, and family income, parental education, and genetics could influence both reading frequency and vocabulary. The result is a correlation consistent with, but not proof of, a causal effect.

Question 33Human Growth and Development

A child who is generally cheerful, adapts quickly to new routines, and shows mild reactions to new stimuli would be classified by temperament researchers as which type?

  1. Unclassified temperament
  2. Difficult temperament
  3. Easy temperament Correct answer.
  4. Slow-to-warm-up temperament

Explanation

The easy temperament pattern combines positive mood, regularity, quick adaptation, and mild-to-moderate responses to novelty. The description matches all of these features.

Question 34Human Growth and Development

In Ainsworth's strange situation, a toddler who explores freely while the caregiver is present, shows distress when she leaves, and is quickly comforted on her return is displaying which attachment pattern?

  1. Secure attachment Correct answer.
  2. Disorganized attachment
  3. Avoidant attachment
  4. Resistant attachment

Explanation

Secure attachment is marked by using the caregiver as a safe base for exploration, distress at separation, and prompt comfort upon reunion. The described pattern fits all three criteria.

Question 35Human Growth and Development

Which statement best describes the direction of the secular trend in pubertal timing in many industrialized countries during the twentieth century?

  1. Menarche now typically occurs before age eight in most girls
  2. The average age of menarche remained fixed across all populations
  3. The average age of menarche rose steadily due to increased academic stress
  4. The average age of menarche declined, largely due to improved nutrition and health Correct answer.

Explanation

Documented secular trends show earlier menarche over the past century in many industrialized nations, attributed mainly to better nutrition, reduced disease burden, and improved living conditions. The trend has slowed or plateaued in some recent cohorts.

Question 36Human Growth and Development

A 16-year-old begins to argue that a law is unjust by imagining a society without it and evaluating the consequences for fairness. This reasoning best illustrates which of Piaget's stages?

  1. Preoperational stage
  2. Concrete operational stage
  3. Sensorimotor stage
  4. Formal operational stage Correct answer.

Explanation

Formal operational thought enables hypothetical reasoning, consideration of abstract principles such as justice, and systematic evaluation of imagined possibilities. Imagining a society without a law and weighing consequences is exactly this kind of reasoning.

Question 37Human Growth and Development

Research on adolescent brain development indicates that which pattern best explains increases in risk-taking behavior during the teenage years?

  1. Prefrontal control systems mature earlier than reward-seeking systems
  2. Reward-seeking systems mature earlier than prefrontal control systems Correct answer.
  3. Both systems mature simultaneously in early childhood
  4. The amygdala is fully mature at birth while the cortex never develops further

Explanation

Dual-systems accounts propose that limbic reward circuitry becomes highly responsive around puberty while prefrontal regulatory regions continue maturing into the mid-twenties. This gap is thought to heighten sensation seeking and risk-taking in adolescence.

Question 38Human Growth and Development

A student stays up late studying, feels anxious about an exam, and then performs well. According to the Yerkes-Dodson principle, which statement best describes the general relationship between arousal and performance?

  1. Performance is best at moderate arousal, with optimal level varying by task difficulty Correct answer.
  2. Performance is best at the lowest possible arousal for every task
  3. Performance is unrelated to arousal in any measurable way
  4. Performance rises steadily with arousal regardless of task difficulty

Explanation

The Yerkes-Dodson principle holds that performance peaks at intermediate arousal, with simpler tasks tolerating higher arousal and complex tasks requiring lower arousal. The inverted-U relationship captures this pattern.

Question 39Human Growth and Development

A new mother reports feeling tearful and overwhelmed in the days after delivery but improves within two weeks without treatment. This pattern is most consistent with which condition?

  1. Postpartum depression
  2. Postpartum blues Correct answer.
  3. Generalized anxiety disorder
  4. Postpartum psychosis

Explanation

Postpartum blues are common, typically begin within days of delivery, and resolve within about two weeks without clinical intervention. Postpartum depression is more persistent and impairing, often lasting weeks to months.

Question 40Human Growth and Development

Which statement best characterizes the typical developmental sequence of peer play in early childhood?

  1. Onlooker behavior appears only after cooperative play is established
  2. Cooperative play precedes parallel play, which precedes solitary play
  3. Solitary play precedes parallel play, which precedes cooperative play Correct answer.
  4. Parallel play is the final and most mature form of play

Explanation

Peer play generally progresses from solitary and onlooker behavior to parallel play, then associative and cooperative play as social skills develop. The order reflects increasing social engagement and shared goals.

Question 41Human Growth and Development

A 70-year-old performs as well as younger adults on a test of vocabulary but more slowly on a test requiring rapid mental rotation of unfamiliar shapes. Which theoretical account best explains this pattern?

  1. Neither ability changes with age after age 65
  2. Both fluid and crystallized abilities decline at identical rates
  3. Crystallized abilities are maintained while fluid abilities decline with age Correct answer.
  4. Fluid abilities are maintained while crystallized abilities decline with age

Explanation

Crystallized intelligence, which draws on accumulated knowledge such as vocabulary, tends to hold steady or grow, whereas fluid abilities involving speed and novel reasoning show average declines. The described pattern is the standard dissociation.

Question 42Human Growth and Development

Which statement best describes the relationship between identity status and the exploration-commitment framework?

  1. Achievement requires prior exploration followed by commitment Correct answer.
  2. Moratorium involves commitment without exploration
  3. Diffusion involves firm commitment after extensive exploration
  4. Foreclosure involves active exploration without commitment

Explanation

Identity achievement is defined as commitment following a period of active exploration of alternatives. The other statuses are distinguished by whether exploration and commitment are present or absent.

Question 43Human Growth and Development

A researcher studying aging follows the same group of adults every five years for thirty years. Which design is being used, and what is its main limitation?

  1. Cross-sectional design, limited by cohort effects
  2. Case study design, limited by lack of repeated measurement
  3. Sequential design, limited by the absence of age comparisons
  4. Longitudinal design, limited by practice effects and selective attrition Correct answer.

Explanation

A longitudinal design tracks one cohort repeatedly over time, which controls cohort effects but risks practice effects from repeated testing and attrition of participants. Those are its principal methodological weaknesses.

Question 44Human Growth and Development

Which statement best describes the typical pattern of attachment formation across the first year?

  1. Indiscriminate social responsiveness gives way to preference for familiar caregivers and then to focused attachment Correct answer.
  2. Focused attachment to one caregiver is present at birth and remains unchanged
  3. Attachment to peers develops before attachment to caregivers
  4. Infants show no preference for caregivers until about 18 months

Explanation

Attachment develops in phases, beginning with undiscriminating responsiveness, moving to preference for familiar figures, and culminating in focused attachment to specific caregivers in the second half of the first year. Multiple attachments then broaden.

Question 45Human Growth and Development

A child is shown a model of a room with a hidden toy and then asked to find the toy in the actual room. Success on this task indicates development of which ability?

  1. Phonological awareness
  2. Spatial representation and dual encoding of a scale model Correct answer.
  3. Conservation of number
  4. Reciprocal prosocial behavior

Explanation

Success on scale-model search tasks requires representing a small model and the larger room simultaneously and mapping locations between them. This ability typically emerges in the preschool years.

Question 46Human Growth and Development

A child who understands that a person can hold a false belief about where a toy is hidden is most likely to have developed which capacity?

  1. Object permanence
  2. Conservation
  3. Theory of mind Correct answer.
  4. Centration

Explanation

Passing false-belief tasks demonstrates theory of mind, the understanding that others can hold beliefs that differ from reality. This milestone typically appears around age four.

Question 47Human Growth and Development

Which statement best describes the relationship between the timing of pubertal maturation and psychosocial adjustment in adolescence?

  1. Early-maturing boys and late-maturing girls are generally at elevated risk
  2. Early-maturing girls and late-maturing boys are generally at elevated risk for adjustment difficulties Correct answer.
  3. Late maturation is uniformly protective for both sexes
  4. Maturation timing shows no consistent relationship with adjustment

Explanation

Research generally finds early-maturing girls face elevated risk, such as body-image concerns and association with older peers, while late-maturing boys experience more adjustment difficulties. The effects are modest and moderated by context.

Question 48Human Growth and Development

A clinician notes that an older adult has difficulty recalling a new neighbor's name after one introduction but remembers it when given a cue. This pattern most likely reflects which change?

  1. A progressive dementia requiring immediate diagnosis
  2. A hearing impairment rather than a memory change
  3. Complete loss of long-term memory storage
  4. Age-related decline in free recall that is partly offset by cuing Correct answer.

Explanation

Older adults often show reduced free recall while benefiting substantially from retrieval cues, consistent with encoding and retrieval inefficiency rather than lost storage. Improvement with cuing argues against profound memory loss.

Question 49Human Growth and Development

Which statement best describes the role of the Apgar score in newborn assessment?

  1. It predicts later intelligence and school achievement
  2. It measures the newborn's length and head circumference
  3. It diagnoses genetic disorders through blood analysis
  4. It rates heart rate, respiration, muscle tone, reflexes, and color shortly after birth Correct answer.

Explanation

The Apgar score evaluates five signs, heart rate, respiratory effort, muscle tone, reflex irritability, and color, at one and five minutes after birth. It is a quick index of immediate condition, not a long-term predictor.

Question 50Human Growth and Development

A researcher wants to examine whether a new parenting program improves parent-child communication. Which research design would best allow her to draw causal conclusions?

  1. A correlational study
  2. A randomized controlled trial Correct answer.
  3. A cross-sectional survey
  4. A case study

Explanation

A randomized controlled trial is the gold standard for establishing causality because random assignment to conditions helps control for confounding variables. Correlational and cross-sectional designs can show associations but cannot establish cause and effect, and case studies lack generalizability and control.
