,1. A researcher proposes that cognitive development proceeds through a fixed
sequence of stages, each characterized by qualitatively different reasoning abilities.
However, a critic argues that the stages are not as universal as claimed, citing
evidence that some individuals never reach the highest stage and that performance
can be influenced by training and context. Which theoretical position does the critic
best support?
A. Piaget's constructivist stage theory
B. Vygotsky's sociocultural theory
C. Information-processing theory
D. Dynamic systems theory
Answer: B. Vygotsky's sociocultural theory
Vygotsky's sociocultural theory emphasizes that cognitive development is mediated by
social interaction and cultural tools, and that the potential for development (zone of
proximal development) varies with support. This contrasts with Piaget's universal stage
theory. Information-processing and dynamic systems theories focus on mechanisms but
do not specifically argue against universality based on social context.
2. In a longitudinal study of attachment, researchers find that infants classified as
insecure-avoidant at 12 months are more likely to show externalizing behaviors at
age 5, but only if their mothers reported high levels of parenting stress. This finding
illustrates which concept?
A. Main effect of attachment on behavior
B. Mediation
C. Moderation
D. Confounding
Answer: C. Moderation
Moderation occurs when the relationship between two variables (attachment and
behavior) depends on a third variable (parenting stress). The effect of attachment on
behavior is present only under high stress, indicating that stress moderates the
association. Mediation would require that attachment influences behavior through an
intermediate variable. A main effect would show a direct relationship regardless of
stress, and confounding would involve a third variable causing both.

,3. A researcher uses functional magnetic resonance imaging (fMRI) to examine
brain activity in adolescents while they perform a risk-taking task. Compared to
adults, adolescents show greater activation in the ventral striatum and less activation
in the prefrontal cortex. This pattern is most consistent with which model of
adolescent brain development?
A. Maturational imbalance model
B. Dual-systems model
C. Social information processing model
D. Cognitive control model
Answer: B. Dual-systems model
The dual-systems model posits that adolescent risk-taking results from an imbalance
between early-developing limbic regions (ventral striatum) and later-developing
prefrontal control regions. The maturational imbalance model is similar but
emphasizes the gap between emotional and cognitive systems. However, the
dual-systems model specifically highlights the ventral striatum and prefrontal cortex.
Social information processing and cognitive control models do not focus on brain
maturation as the primary driver.
4. A study finds that children who attend high-quality preschool programs score
higher on cognitive tests at age 4, but by age 8 the effect has disappeared. However,
at age 25, these same individuals have higher incomes and lower rates of criminality.
This pattern exemplifies which phenomenon?
A. Sleeper effect
B. Fade-out effect
C. Cohort effect
D. Testing effect
Answer: A. Sleeper effect
The sleeper effect occurs when an intervention shows little immediate impact but
emerges later in life. Here, cognitive gains faded, but long-term benefits in income and
crime appeared. Fade-out refers to the initial gains disappearing, which is part of the
pattern, but the later emergence of different outcomes is the sleeper effect. Cohort
effects relate to generational differences, and testing effects refer to practice effects
from repeated testing.

, 5. A developmental psychologist argues that the human mind is composed of
specialized modules that evolved to solve specific adaptive problems, such as face
recognition or language acquisition. This perspective is most closely aligned with:
A. Behaviorism
B. Piagetian theory
C. Evolutionary psychology
D. Ecological systems theory
Answer: C. Evolutionary psychology
Evolutionary psychology posits domain-specific modules shaped by natural selection.
Behaviorism rejects innate modules. Piagetian theory focuses on general cognitive
structures that change with development. Ecological systems theory emphasizes
environmental contexts, not innate modules.
6. In a twin study on empathy, monozygotic twins show a correlation of 0.60, while
dizygotic twins show a correlation of 0.40. Assuming equal environments, what is the
approximate heritability estimate?
A. 0.20
B. 0.40
C. 0.60
D. 0.80
Answer: B. 0.40
Heritability is estimated using Falconer's formula: 2*(rMZ - rDZ) = 2*(0.60 - 0.40) =
0.40. This indicates that 40% of the variance in empathy in this population is due to
genetic factors. The shared environment estimate is rMZ - h^2 = 0.60 - 0.40 = 0.20, and
the nonshared environment is 1 - rMZ = 0.40.
