,Q1. A researcher uses a dual-task paradigm where participants perform a visual search task while
simultaneously listening to a series of digits. Performance on the visual search task declines when the digits
are semantically related to the visual targets, but not when they are unrelated. Which theoretical account
best explains this pattern?
A. Late selection theory, because semantic processing occurs without attention
B. Resource theory, because the tasks compete for limited central resources
C. Feature integration theory, because binding requires focal attention
D. Attentional blink, because the second target is missed during processing of the first
Correct Answer: A. Late selection theory, because semantic processing occurs without attention
Rationale: Late selection theory posits that all stimuli are processed semantically before selection, so semantic
relatedness between tasks should cause interference even when the unattended channel is not consciously
perceived. Resource theory predicts general interference but not specifically based on semantic relatedness.
Feature integration theory addresses visual binding, not cross-modal interference. Attentional blink is a temporal
phenomenon, not relevant to simultaneous tasks.
Why Wrong:
B - Resource theory predicts interference from any dual-task load, not specifically from semantic relatedness.
C - Feature integration theory explains visual feature binding, not cross-modal semantic interference.
D - Attentional blink describes a deficit in detecting a second target within a rapid stream, not simultaneous
task interference.

Q2. In a classic study, participants studied lists of words and then recalled them in the same or a different
environmental context. Recall was better when the context matched. However, subsequent research showed
that this effect is eliminated when participants are instructed to mentally reinstate the original context at test.
What does this suggest about the mechanisms underlying context-dependent memory?
A. Context acts as a retrieval cue only when physical reinstatement is possible
B. Context effects are primarily due to encoding specificity, not mental imagery
C. Context-dependent memory reflects the influence of ambient environmental cues on retrieval strategies
D. Mental reinstatement overrides the need for physical context by activating the same neural representations
Correct Answer: D. Mental reinstatement overrides the need for physical context by activating the same
neural representations
Rationale: Mental reinstatement allows participants to internally generate the retrieval cues associated with the
original context, effectively simulating physical context. This suggests that context effects are mediated by the
activation of context-specific neural patterns, which can be initiated either externally or internally. Encoding
specificity emphasizes the match between encoding and retrieval conditions, but mental reinstatement demonstrates
that this match need not be physical.
Why Wrong:
A - Physical reinstatement is not necessary; mental reinstatement can produce the same benefit.
B - Mental reinstatement is a form of imagery that still relies on encoding specificity principles.
C - Context effects are more about automatic cuing than deliberate retrieval strategies.

Q3. A patient with damage to the left inferior frontal gyrus (Broca's area) is asked to describe a picture. The
patient's speech is slow, effortful, and telegraphic, but comprehension appears intact. Which of the following
best characterizes the underlying deficit?
A. Impaired access to phonological representations of words
B. Deficit in syntactic processing required for grammatical sentence production
Page 3
, C. Loss of semantic knowledge for action words
D. Difficulty in planning the motor sequences for speech articulation
Correct Answer: B. Deficit in syntactic processing required for grammatical sentence production
Rationale: Broca's aphasia is primarily a disorder of grammatical production; patients have difficulty constructing
syntactically complex sentences but retain word meaning and comprehension. Phonological access (A) is more associated with
anomia or conduction aphasia. Semantic knowledge (C) is typically preserved. Motor planning (D) describes apraxia of
speech, which can co-occur but is not the core deficit in Broca's aphasia.
Why Wrong:
A - Phonological access deficits are characteristic of anomic aphasia, not Broca's.
C - Semantic knowledge is generally intact in Broca's aphasia.
D - Motor planning deficits are seen in apraxia of speech, which may co-occur but is distinct from the grammatical
deficit.

Q4. In a visual search task, participants search for a red circle among red squares and blue circles. Reaction
times increase linearly with set size. Which type of search is this, and what does it imply about attentional
processing?
A. Feature search; attention is not required because the target differs by a single feature
B. Conjunction search; attention must bind features across dimensions
C. Spatial search; attention is guided by location-based cues
D. Parallel search; all items are processed simultaneously
Correct Answer: B. Conjunction search; attention must bind features across dimensions
Rationale: The target shares a feature (color) with some distractors and another feature (shape) with other
distractors, so it is defined by a conjunction of features. Conjunction search requires serial attention to bind
features, leading to linear RT × set size slopes. Feature search (A) would produce flat slopes. Spatial search (C) is
not a standard category. Parallel search (D) would also yield flat slopes.
Why Wrong:
A - Feature search would show flat RT slopes because the target pops out.
C - Spatial search is not a standard classification; the key distinction is feature vs. conjunction.
D - Parallel search implies flat slopes, not linear increases.

12(1), 97-136.
Q5. A researcher presents a list of 20 words at a rate of one word per second. Participants are asked to recall
the words in any order immediately after presentation. The serial position curve shows a pronounced
primacy effect but no recency effect. Which experimental manipulation would most likely produce this
pattern?
A. Presenting the words at a faster rate (e.g., 200 ms per word)
B. Requiring participants to count backwards for 30 seconds after the last word before recall
C. Using semantically related words instead of unrelated words
D. Instructing participants to use a rehearsal strategy focusing on the first few words
Correct Answer: B. Requiring participants to count backwards for 30 seconds after the last word before
recall
Rationale: A delay filled with a distractor task (counting backwards) eliminates the recency effect because the last
few items are displaced from short-term memory. The primacy effect remains because those items have been
rehearsed and transferred to long-term memory. Faster presentation (A) would reduce primacy. Semantic
relatedness (C) would improve overall recall but not selectively eliminate recency. Rehearsal focus (D) would
enhance primacy but not eliminate recency.
