2Solutions

1.Cognitive psychology

Answer: D · 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.

Answer

D · Mainly codes verbal information acoustically
2.Cognitive psychology

Answer: D · The main cost of phoning while driving is attentional, not manual

Why this is the answer

Because the impairment did not depend on holding the phone, it arises from dividing attention between the conversation and the driving task.

Answer

D · The main cost of phoning while driving is attentional, not manual
3.Developmental psychology

Answer: A · Can tell two stimuli apart because interest returns when the stimulus changes

Why this is the answer

When a familiar stimulus is replaced by a new one, a recovery in looking time (dishabituation) shows the infant perceives the difference.

Answer

A · Can tell two stimuli apart because interest returns when the stimulus changes
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.

Answer

B · Have basic expectations about small numbers
5.Social psychology

Answer: D · False consensus effect

Why this is the answer

The false consensus effect is the tendency to overestimate how common our own attitudes and behaviours are.

Answer

D · False consensus effect
6.Social psychology

Answer: A · Be motivated to do the opposite of what is urged

Why this is the answer

Psychological reactance (Brehm) is the motivation to restore threatened freedom, often by resisting or doing the forbidden behaviour.

Answer

A · Be motivated to do the opposite of what is urged
7.Clinical psychology

Answer: D · Antisocial personality disorder

Why this is the answer

Antisocial personality disorder includes deceitfulness, impulsivity, aggression and lack of remorse, with evidence of conduct disorder in childhood.

Answer

D · Antisocial personality disorder
8.Clinical psychology

Answer: D · Interoceptive exposure, so the client learns bodily sensations are not dangerous

Why this is the answer

Interoceptive exposure provokes feared bodily sensations so the client can test catastrophic predictions and habituate. It is a core part of CBT for panic disorder.

Answer

D · Interoceptive exposure, so the client learns bodily sensations are not dangerous
