1. A 75-year-old patient presents with symptoms suggesting early-stage cognitive decline. When
evaluating the patient's performance using the Information Processing Perspective, which factor
is most likely responsible for their diminished performance on complex memory tasks?
A. A reduction in the total capacity of long-term memory storage
B. A decrease in processing speed and the efficiency of the working memory system
C. The complete loss of crystallized intelligence over the lifespan
, D. An inability to access semantic knowledge stored during early adulthood
CORRECT ANSWER : B
Rationale: The information processing perspective emphasizes that cognitive decline in late
adulthood is frequently linked to reduced processing speed and working memory efficiency
rather than a loss of long-term storage capacity. Option A is incorrect because long-term
memory capacity remains largely stable. Options C and D are incorrect because crystallized
intelligence and semantic knowledge are typically maintained or increased in late adulthood.
2. A developmental psychologist is analyzing the impact of "Age-Related Positivity Effect" on a
subject's emotional regulation. Which scenario best demonstrates this phenomenon?
A. A younger adult focusing on negative feedback to improve performance
B. An older adult prioritizing emotional gratification by selectively attending to positive
stimuli
C. A mid-life adult experiencing a crisis due to unresolved childhood trauma
D. An elderly patient becoming depressed due to chronic physical illness
CORRECT ANSWER : B
Rationale: The positivity effect describes the tendency for older adults to prioritize positive
emotional information over negative information to enhance emotional regulation. Option A
describes the younger adult tendency toward negative feedback for self-improvement. Option C
and D refer to psychological states that do not illustrate the specific mechanism of selective
emotional focus.
3. According to the "Selective Optimization with Compensation" (SOC) model, how should an
aging professional handle a decline in physical dexterity while maintaining high performance in
their craft?
A. Resigning from the profession to avoid the frustration of declining skills
B. Ignoring the physical limitations and continuing to work at the same pace as in youth
C. Selecting specific high-value tasks, practicing them, and utilizing assistive technologies
D. Shifting focus entirely to abstract theory without any practical application
CORRECT ANSWER : C
Rationale: SOC suggests that individuals manage aging by selecting specific goals, optimizing
their performance through practice, and compensating for lost abilities with new methods or
, tools. Option A represents disengagement. Option B is unrealistic and ignores the adaptive
nature of development. Option D does not address the core requirement of maintaining
professional performance.
4. Which of the following best describes the structural changes in the brain associated with
"scaffolding" in the STAC-r model of cognitive aging?
A. The complete degradation of neural pathways leading to total cognitive failure
B. The recruitment of additional, often bilateral, neural circuits to compensate for
declining efficiency
C. The replacement of lost neurons with stem cells during late adulthood
D. A decrease in white matter integrity that prevents any compensatory activity
CORRECT ANSWER : B
Rationale: The Scaffolding Theory of Aging and Cognition (STAC-r) posits that the brain builds
new neural "scaffolding" (often bilateral recruitment) to maintain performance despite neural
degradation. Option A is incorrect because decline is gradual, not absolute. Option C is
biologically inaccurate regarding typical aging. Option D contradicts the premise of the theory
which explains how performance is maintained.
5. A study examines the "Cross-Linked Theory" of aging. Which biological process does this
theory primarily focus on?
A. The shortening of telomeres during cell division
B. The accumulation of free radicals causing cellular damage
C. The stiffening of proteins like collagen due to the formation of cross-links
D. The programmed genetic death of cells (apoptosis)
CORRECT ANSWER : C
Rationale: The Cross-Linked Theory posits that aging is caused by the accumulation of cross-
linked proteins, which interfere with normal cell function and tissue elasticity. Option A refers to
Telomere Theory. Option B refers to Free Radical Theory. Option D refers to Programmed Cell
Death theories.
6. In the context of personality stability in later life, which trait is most likely to show a slight
decline according to the Five-Factor Model?
A. Agreeableness
, B. Conscientiousness
C. Neuroticism
D. Openness to Experience
CORRECT ANSWER : C
Rationale: Longitudinal research on the Five-Factor Model typically shows that neuroticism
tends to decrease slightly as individuals age, as they become better at emotional regulation.
Option A and B often remain stable or increase. Option D is generally associated with stability,
though some decline can occur depending on environmental stimulation.
7. A patient with sarcopenia is struggling with activities of daily living. Which intervention is most
supported by current gerontological research to reverse or mitigate this condition?
A. Complete bed rest to preserve joint health
B. Resistance training combined with adequate protein intake
C. Strict caloric restriction to reduce oxidative stress
D. Increased intake of simple carbohydrates for quick energy
CORRECT ANSWER : B
Rationale: Sarcopenia involves the age-related loss of muscle mass and strength; resistance
training is the gold-standard intervention to stimulate hypertrophy and functional improvement.
Option A would exacerbate muscle atrophy. Option C might lead to further muscle wasting.
Option D does not address the physiological mechanism of muscle loss.
8. Which concept explains the "U-shaped" curve often observed in studies regarding life
satisfaction and age?
A. The rapid decline of health in middle age
B. The adjustment of expectations and increase in emotional regulation during later years
C. The lack of social support systems for younger adults
D. The sudden peak of productivity in one's thirties
CORRECT ANSWER : B
Rationale: The U-shaped curve of happiness suggests that life satisfaction is high in youth, dips
in mid-life due to various stressors, and rebounds in later life as older adults regulate emotions
