1. A researcher is conducting a longitudinal study on cognitive development in middle
childhood. Which of the following best describes the primary advantage of this research
design over cross-sectional studies?
A. It eliminates all sources of participant attrition over time.
B. It directly tracks age-related changes within the same individuals.
C. It is considerably less expensive and faster to complete.
D. It completely controls for cohort and historical period effects.
Longitudinal studies evaluate the exact same participants repeatedly as they age, making
them uniquely suited to track individual developmental trajectories and intra-individual
change over time.
2. During a developmental psychology assessment, a 4-year-old child insists that if a piece
of clay is rolled into a long snake, it suddenly contains more clay. According to Piaget, what
cognitive limitation is this child demonstrating?
A. Egocentrism
B. Centration
C. Seriation
D. Transductive reasoning
Centration is the tendency to focus on only one salient dimension of an object—such as
length—while ignoring other relevant dimensions, which directly prevents preoperational
children from understanding conservation.
3. A school counselor observes a high school student who withdraws from peer groups,
shows a sudden drop in academic performance, and expresses chronic feelings of
worthlessness. Which theoretical framework best guides the initial evaluation of potential
adolescent depression?
A. Psychosocial moratorium theory
B. Social learning theory
C. Diathesis-stress model
D. Conventional moral reasoning
The diathesis-stress model posits that psychological disorders emerge from an interaction
between underlying biological or psychological vulnerabilities and environmental stressors.
,4. An infant turns their head and begins sucking motions when their cheek is stroked by a
caregiver. What primitive neonatal reflex does this behavior illustrate?
A. Moro reflex
B. Babinski reflex
C. Tonic neck reflex
D. Rooting reflex
The rooting reflex is an automatic, unlearned survival response in newborns that helps them
locate a food source, such as a nipple, by turning toward tactile stimulation on the cheek.
5. According to Erik Erikson’s stages of psychosocial development, a middle-aged adult
who focuses on mentoring younger colleagues, contributing to community development,
and raising children is successfully navigating which crisis?
A. Identity versus role confusion
B. Intimacy versus isolation
C. Generativity versus stagnation
D. Integrity versus despair
Generativity versus stagnation defines middle adulthood, where individuals strive to
establish, guide, and contribute to the next generation through parenting, mentoring, and
productive work.
6. A developmental psychologist evaluates an adult client who shows impairments in
executive functioning, working memory inhibition, and processing speed. Brain imaging
reveals localized atrophy primarily in which cerebral structure most associated with
cognitive aging?
A. Occipital lobe
B. Prefrontal cortex
C. Primary visual cortex
D. Cerebellar vermis
The prefrontal cortex undergoes disproportionate age-related structural and functional
decline compared to other brain regions, directly impacting higher-order cognitive functions
like working memory and inhibition.
7. A mother uses consistent warmth, clear boundary enforcement, and encourages open
communication while respecting her adolescent's growing autonomy. According to
Baumrind, what parenting style is being exhibited?
A. Authoritarian
B. Authoritative
C. Permissive
D. Uninvolved
,Authoritative parenting balances high demandingness with high responsiveness, fostering
optimal socioemotional outcomes, self-reliance, and secure identity formation in children and
adolescents.
8. In a classic developmental experiment, an infant shows distress when the mother leaves
the room but is easily comforted upon her return, actively seeking contact. What
attachment classification does this infant display?
A. Secure attachment
B. Anxious-avoidant attachment
C. Anxious-ambivalent attachment
D. Disorganized-disoriented attachment
Secure attachment is characterized by using the caregiver as a secure base for exploration,
displaying appropriate distress upon separation, and seeking immediate comfort upon
reunion.
9. A toddler points to a toy airplane flying overhead and looks back at their mother to
verify her attention. This early social communication milestone is known as:
A. Social referencing
B. Joint attention
C. Habituation
D. Deferred imitation
Joint attention involves two individuals focusing on the same object or event via gaze-
following and pointing, marking a crucial foundational milestone in social-cognitive
development.
10. A child learns that domestic cats are furry and have four legs. When seeing a small dog
for the first time, the child calls it a "cat." According to Piagetian theory, this cognitive
process is called:
A. Accommodation
B. Equilibration
C. Assimilation
D. Conservation
Assimilation occurs when an individual interprets new environmental information using
preexisting mental schemas without altering the underlying cognitive structures.
11. Which of the following teratogens is most directly linked to distinct craniofacial
abnormalities, central nervous system dysfunction, and severe growth restriction in
prenatal development?
, A. Folic acid deficiency
B. Alcohol
C. Low-level caffeine
D. Acetaminophen
Prenatal exposure to alcohol is a potent teratogen that causes fetal alcohol spectrum
disorders, characterized by distinct facial features, growth deficits, and permanent
neurological impairments.
12. A researcher assesses moral reasoning by presenting the Heinz dilemma. An adult
participant argues that stealing the drug is wrong because it violates the written penal code
and disrupts social order. At what stage of Kohlberg’s moral development is this
participant operating?
A. Stage 1: Obedience and punishment orientation
B. Stage 3: Interpersonal concordance orientation
C. Stage 4: Authority and social-order maintaining orientation
D. Stage 6: Universal ethical principles orientation
Stage 4 reasoning emphasizes adherence to laws, rules, and societal duties to maintain social
order and ensure the smooth functioning of society.
13. A preschooler incorrectly believes that the moon is following them home because it
remains visible while their car moves. What egocentric cognitive bias does this scenario
illustrate?
A. Animism
B. Artificialism
C. Centration
D. Realism error
Animism is the preoperational tendency to attribute lifelike qualities, intentions, and agency
to inanimate objects or natural phenomena.
14. An older adult successfully adapts to age-related sensory declines and physical
limitations by engaging in hobbies that require fewer physical demands while deepening
mastery in creative writing. This adaptation reflects which psychological theory of aging?
A. Disengagement theory
B. Activity theory
C. Socioemotional selectivity theory
D. Selective optimization with compensation
Selective optimization with compensation involves maximizing functional gains through
focused practice while substituting alternative strategies to manage age-related losses.
