Question 1: Which cognitive phenomenon best explains why individuals often fail
to notice a prominent visual change when their attention is focused elsewhere?
A. Change blindness
B. Inattentional blindness
C. Attentional blink
D. Visual masking
CORRECT ANSWER: A. Change blindness
RATIONALE:Change blindness occurs when a substantial alteration in a visual scene
goes unnoticed, typically because attention is not directed toward the changing
element. It differs from inattentional blindness, which involves failing to perceive an
unexpected stimulus in plain sight. Both highlight the selective nature of visual
attention, but change blindness specifically addresses failure to detect modifications
between sequential views.
Question 2: In Baddeley and Hitch's model of working memory, which component
is primarily responsible for the temporary storage and manipulation of auditory and
verbal information?
A. Visuospatial sketchpad
B. Central executive
C. Phonological loop
D. Episodic buffer
CORRECT ANSWER: C. Phonological loop
RATIONALE:The phonological loop is the working memory subsystem dedicated to
holding and rehearsing speech-based information. It consists of a phonological store
and an articulatory rehearsal process, enabling short-term retention of verbal material.
The visuospatial sketchpad handles visual and spatial data, the central executive
allocates attention, and the episodic buffer integrates information across systems.
Question 3: Which heuristic describes the tendency to judge the probability of an
event based on how easily examples come to mind?
A. Representativeness heuristic
B. Anchoring and adjustment heuristic
,C. Availability heuristic
D. Affect heuristic
CORRECT ANSWER: C. Availability heuristic
RATIONALE:The availability heuristic relies on the ease of retrieval from memory to
estimate likelihood or frequency. When examples are readily accessible, individuals
overestimate the event's probability. This contrasts with the representativeness
heuristic, which assesses similarity to a prototype, and anchoring, which relies on initial
reference points.
Question 4: According to levels-of-processing theory, which encoding strategy
yields the most durable long-term memory traces?
A. Structural processing
B. Phonemic processing
C. Semantic processing
D. Visual processing
CORRECT ANSWER: C. Semantic processing
RATIONALE:Levels-of-processing theory posits that deeper, meaning-based encoding
produces stronger and more retrievable memory traces than shallow structural or
phonemic processing. Semantic encoding involves analyzing the significance and
relationships of information, facilitating richer associative networks that enhance long-
term retention.
Question 5: Which phenomenon occurs when prior learning interferes with the
acquisition of new information?
A. Retroactive interference
B. Proactive interference
C. Decay theory
D. Retrieval failure
CORRECT ANSWER: B. Proactive interference
RATIONALE:Proactive interference occurs when previously stored memories disrupt
the encoding or retrieval of newly learned material. Retroactive interference works in
the opposite direction, where new learning impairs recall of old information. Decay
theory attributes forgetting to the passive fading of memory traces over time.
Question 6: In the Stroop effect, participants experience slower reaction times
when asked to:
A. Name the color of ink when the word spells a different color
B. Read color words printed in black ink
C. Identify shapes embedded within complex figures
D. Match pairs of semantically related words
,CORRECT ANSWER: A. Name the color of ink when the word spells a different color
RATIONALE:The Stroop effect demonstrates automaticity in reading and cognitive
control demands. When word meaning conflicts with ink color, the automatic reading
process interferes with the deliberate task of color naming, requiring inhibitory control
from the anterior cingulate cortex and prefrontal regions.
Question 7: Which memory system is characterized by brief retention of sensory
input before selective attention filters it for further processing?
A. Working memory
B. Sensory memory
C. Procedural memory
D. Episodic memory
CORRECT ANSWER: B. Sensory memory
RATIONALE:Sensory memory briefly retains raw perceptual information in its original
modality for a few hundred milliseconds to a few seconds. Iconic and echoic memory
are visual and auditory subtypes. It serves as a buffer that allows attentional
mechanisms to select relevant information for transfer to working memory.
Question 8: The spacing effect in learning research demonstrates that:
A. Massed practice leads to superior long-term retention compared to distributed
practice
B. Distributed practice yields better long-term retention than massed practice
C. Immediate testing immediately after learning maximizes consolidation
D. Interleaving unrelated topics eliminates contextual interference
CORRECT ANSWER: B. Distributed practice yields better long-term retention than
massed practice
RATIONALE:The spacing effect shows that distributing study sessions over time
enhances long-term retention compared to cramming. This benefit arises from repeated
retrieval opportunities, contextual variability, and enhanced consolidation processes
that strengthen synaptic connections and reduce forgetting.
Question 9: Which brain region is most critically associated with the consolidation
of declarative memories?
A. Amygdala
B. Hippocampus
C. Cerebellum
D. Basal ganglia
CORRECT ANSWER: B. Hippocampus
RATIONALE:The hippocampus plays a central role in encoding and consolidating
declarative memories, which include facts and events. While the amygdala modulates
, emotional memory, the cerebellum and basal ganglia support procedural and motor
learning. Damage to the hippocampus typically results in anterograde amnesia.
Question 10: In dual-process theories of reasoning, System 1 is characterized by:
A. Slow, deliberate, and analytical processing
B. Fast, automatic, and intuitive processing
C. Rule-based sequential computation
D. High cognitive load and executive control demands
CORRECT ANSWER: B. Fast, automatic, and intuitive processing
RATIONALE:Dual-process models distinguish between System 1 (fast, automatic,
heuristic-driven) and System 2 (slow, effortful, analytical). System 1 operates with
minimal conscious awareness and low cognitive load, while System 2 engages when
tasks require deliberate reasoning, error monitoring, or override of intuitive responses.
Question 11: Which phenomenon explains why witnesses often incorporate post-
event information into their original memory of an event?
A. Source monitoring error
B. Misinformation effect
C. Flashbulb memory formation
D. Context-dependent recall
CORRECT ANSWER: B. Misinformation effect
RATIONALE:The misinformation effect occurs when exposure to misleading post-event
information alters or contaminates original memories. This demonstrates the
reconstructive nature of memory, where recall integrates both stored traces and
subsequently acquired details, often without awareness of the source.
Question 12: According to signal detection theory, a "hit" occurs when:
A. A stimulus is present and correctly identified
B. A stimulus is absent but reported as present
C. A stimulus is present but reported as absent
D. A stimulus is absent and correctly identified as absent
CORRECT ANSWER: A. A stimulus is present and correctly identified
RATIONALE:Signal detection theory categorizes perceptual decisions into hits, misses,
false alarms, and correct rejections based on stimulus presence and response. A hit
reflects accurate detection, demonstrating both sensory sensitivity and decision
criterion placement.
Question 13: Which cognitive bias describes the tendency to overestimate one's
own ability to predict outcomes after they have occurred?
A. Confirmation bias
B. Hindsight bias
