1Practice problems
1.Cognitive psychologyMedium
People recall more words from a list of short words (e.g. "cat, sun") than from a list of long words. The usual explanation is that:
- AShort words are held in iconic memory as well as acoustically
- BLong words are processed more deeply and so crowd each other out
- CLong words cause retroactive interference with earlier items
- DShort words take less time to rehearse in the phonological loop
2.Cognitive psychologyHard
In Posner's cueing task, responses are faster after a valid cue and slower after an invalid cue, even when the eyes do not move. This shows that:
- AAttention always follows the direction of gaze
- BAttention can shift to a location without moving the eyes
- CCues have no real effect on how fast targets are processed
- DPeripheral vision cannot detect targets without eye movement
3.Developmental psychologyMedium
A 3-year-old hears a new word once, "This is the chromium tray", and later picks out the correct tray. This is called:
- AOverextension
- BTelegraphic speech
- CFast mapping
- DBabbling
4.Developmental psychologyHard
A longitudinal design is preferred over a cross-sectional design when a researcher wants to:
- AGet results as quickly as possible
- BCompare different age groups at a single time point
- CAvoid any participant drop-out
- DTrack how the same individuals change over time
5.Social psychologyMedium
In Asch's impression studies, changing one word in a list of traits from "warm" to "cold" greatly changed the overall impression. This suggests "warm" is a:
- APeripheral trait
- BStereotype
- CPrimacy cue only
- DCentral trait
6.Social psychologyHard
Steele and Aronson found that Black students did worse than White students on a hard verbal test when it was described as a measure of ability, but equally well when it was described as a non-diagnostic task. This shows that:
- AHard verbal tests are equally difficult for every student
- BFraming a test can create performance gaps via stereotype threat
- CThe way a test is described has no effect on how well people perform
- DAbility differences between groups are fixed and cannot change
7.Clinical psychologyMedium
In the two-factor model of phobias (Mowrer), how is a phobia maintained?
- APositive reinforcement of fear by rewards
- BPunishment of approach behaviour by others, which strengthens the fear itself
- CThe fear is learned by watching others only
- DAvoidance reduces anxiety, which negatively reinforces the avoidance
8.Clinical psychologyHard
The "scientist-practitioner" (Boulder) model in clinical psychology means that clinicians should:
- AAvoid research completely
- BUse research evidence to guide practice and evaluate their own interventions
- COnly conduct laboratory experiments
- DPrescribe medication as their main treatment, following psychiatric guidelines closely
2Solutions
1.Cognitive psychology
Answer: D · Short words take less time to rehearse in the phonological loop
Why this is the answer
The phonological loop holds roughly what can be said in about two seconds, so more short words than long words can be maintained by rehearsal.
D · Short words take less time to rehearse in the phonological loop
2.Cognitive psychology
Answer: B · Attention can shift to a location without moving the eyes
Why this is the answer
Covert orienting moves attention to the cued location, speeding processing there and slowing it elsewhere, independently of where the eyes point.
B · Attention can shift to a location without moving the eyes
3.Developmental psychology
Answer: C · Fast mapping
Why this is the answer
Fast mapping is the ability to form an initial idea of a word's meaning after only one or a few exposures. It helps explain the vocabulary spurt.
4.Developmental psychology
Answer: D · Track how the same individuals change over time
Why this is the answer
Longitudinal studies follow the same people, revealing individual change, but they take long and suffer from attrition. Cross-sectional studies compare different cohorts at one time.
D · Track how the same individuals change over time
5.Social psychology
Answer: D · Central trait
Why this is the answer
Central traits such as warm and cold shape how other traits are interpreted, while peripheral traits have little effect on the overall impression.
6.Social psychology
Answer: B · Framing a test can create performance gaps via stereotype threat
Why this is the answer
When the test seemed to measure ability, the threat of confirming a stereotype impaired performance. Removing that framing removed the gap.
B · Framing a test can create performance gaps via stereotype threat
7.Clinical psychology
Answer: D · Avoidance reduces anxiety, which negatively reinforces the avoidance
Why this is the answer
Fear is acquired through classical conditioning and maintained because avoiding the feared object reduces anxiety, negatively reinforcing avoidance.
D · Avoidance reduces anxiety, which negatively reinforces the avoidance
8.Clinical psychology
Answer: B · Use research evidence to guide practice and evaluate their own interventions
Why this is the answer
The Boulder model trains clinical psychologists to integrate scientific research and clinical practice, the basis of evidence-based practice.
B · Use research evidence to guide practice and evaluate their own interventions
