1Practice problems
1.Cognitive psychologyMedium
Lists of similar-sounding letters (B, G, V, T) are harder to recall immediately than dissimilar letters (F, K, Y, W). This suggests short-term memory:
- AStores letters mainly as visual images of their shapes
- BMainly codes verbal information acoustically
- CHas unlimited capacity for letters
- DMainly codes information by meaning
2.Cognitive psychologyHard
A patient with a long history of heavy alcohol use cannot form new memories and fills gaps with invented stories that he believes. This is typical of:
- ARetrograde amnesia only
- BWernicke's aphasia
- CDissociative amnesia
- DKorsakoff's syndrome
3.Developmental psychologyMedium
A 9-month-old finds a toy hidden under cloth A several times. The toy is then hidden under cloth B in full view, but the infant searches under A again. This is:
- AAnimism
- BConservation failure
- CCentration
- DThe A-not-B error
4.Developmental psychologyHard
Wynn showed 5-month-olds one doll, then a second doll being added behind a screen. When the screen dropped to reveal only one doll, infants looked longer. This suggests infants:
- AHave already learned to count aloud
- BHave basic expectations about small numbers
- CCannot see objects behind screens
- DPrefer one doll to two dolls
5.Social psychologyMedium
Groupthink is most likely when a group:
- ASeeks advice from outside experts
- BIs highly cohesive, isolated and led by a directive leader
- CContains many members who openly disagree and challenge the leader's views
- DUses a formal devil's advocate
6.Social psychologyHard
Myers and Bishop found that students high in prejudice became more prejudiced after discussing racial issues with similar students, and low-prejudice students became less prejudiced. Which two explanations are usually given?
- ASocial loafing and social facilitation
- BPersuasive arguments and social comparison
- CMatching hypothesis and proximity
- DObedience and agentic state
7.Clinical psychologyMedium
Which defence mechanism is shown when someone with strong hostile feelings towards a colleague acts in an excessively friendly way towards them?
- ADenial
- BReaction formation
- CRationalisation
- DDisplacement
8.Clinical psychologyHard
A man reports that his left arm became paralysed after a severe argument, but neurological examination shows findings inconsistent with any known neurological disease. Which DSM-5 diagnosis is most likely?
- AMalingering
- BBody dysmorphic disorder
- CIllness anxiety disorder
- DFunctional neurological symptom disorder (conversion disorder)
2Solutions
1.Cognitive psychology
Answer: B · Mainly codes verbal information acoustically
Why this is the answer
The phonological similarity effect shows that verbal short-term memory relies on sound-based codes. Long-term memory relies more on meaning.
B · Mainly codes verbal information acoustically
2.Cognitive psychology
Answer: D · Korsakoff's syndrome
Why this is the answer
Korsakoff's syndrome causes severe anterograde amnesia, some retrograde amnesia and confabulation, while procedural learning is often relatively preserved.
3.Developmental psychology
Answer: D · The A-not-B error
Why this is the answer
Piaget saw the A-not-B error as evidence that object permanence is still incomplete. Other researchers link it to immature memory and inhibitory control.
4.Developmental psychology
Answer: B · Have basic expectations about small numbers
Why this is the answer
Infants seemed to expect 1 + 1 to make 2. Wynn interpreted this as an early sense of number, though some argue simpler perceptual explanations are possible.
B · Have basic expectations about small numbers
5.Social psychology
Answer: B · Is highly cohesive, isolated and led by a directive leader
Why this is the answer
Janis described groupthink as a drive for consensus that suppresses dissent, typical of cohesive, isolated groups under pressure with a strong leader.
B · Is highly cohesive, isolated and led by a directive leader
6.Social psychology
Answer: B · Persuasive arguments and social comparison
Why this is the answer
Group polarisation is explained by hearing more arguments supporting the initial view and by comparing oneself with others to appear a good group member.
B · Persuasive arguments and social comparison
7.Clinical psychology
Answer: B · Reaction formation
Why this is the answer
Reaction formation turns an unacceptable impulse into its opposite, often in an exaggerated form.
8.Clinical psychology
Answer: D · Functional neurological symptom disorder (conversion disorder)
Why this is the answer
Functional neurological symptom disorder involves motor or sensory symptoms incompatible with recognised neurological conditions. It does not require proof of a psychological cause or that the symptoms are feigned.
D · Functional neurological symptom disorder (conversion disorder)
