1
Q

What is sensory memory?

A

A super acute memory store of a particular modality processed by sense organs - commonest iconic (visual) and echoic (auditory).

Information that is attended to is transferred to the short-term memory store and that that is not attended to is quickly lost

Q

A patient who keeps going to slot machine with the hope of winning big - when he wins what is the operant conditioning mechanism?

A

Variable ratio - he is rewarded after a random number of responses then again after a further random number of responses

Q

How does reciprocal inhibition try to lead to improved emotional/behavioural response?

A

By the principle of trying to ameliorate a feeling with the presence of the opposite

i.e provide ice cream if a fear response is there
Happiness and fear cannot co-exist

Q

What is operant conditioning?

A

Designed to increase a positive behaviour being performed by giving a stimulus immediately after

Positive reinforcement - pleasant stimulus immediately after added
Negative reinforcement - aversive or bad stimulus removed

Can be reinforced continuously or intermittently like a slot machine (intermittent reinforcement develops behaviour resistant to extinction) or Partial reinforcement behaviours are acquired more slowly and extinguish slower.

Q

How do elaborative and maintenance rehearsal differ?

A

Elaborative rehearsal refers to deep processing to allow information to be stored in long term memory it includes forming associations or groupings

Maintenance rehearsal describes the processing that prevents information from leaving short term memory i.e. repeating a phone number again and again while finding a pen

Q

Who proposed the filter theory of attention and what does it describe?

A

David Broadbent proposed the filter theory for attention

He felt a central processor is responsible for selecting which sensory input is attended to. This central processor can switch channel but not more than twice a second. He also felt that information in the unattended channel can only remain there for a few seconds.

This filtering act of the central processor describes the buffer/barrier that exists between sensory and short term/working memory

Q

What is the Ebbinghaus curve?

A

Showed the rate of forgetting of non-sense syllables over a period of time - after 9 hours there is a sharp rate of forgetting with reductions in recall declining after this.

His other experiments showed that forgetting is never complete and some is remembered, that recall during a test period increases chance of remembering and that continuous motor skills i.e. swimming/cycling show no forgetting compared to intermittent motor skills i.e. typing

Q

Outline three types of non-associative learning?

A

Habituation - repeated exposure to a stimulus leads to decreased response

Sensitisation - repeated exposure to a stimulus results in increased response

Pseudoconditioning - emergence of a learned response to a previous neutral stimulus due to exposure of a powerful different stimulus

Q

Outline the three types of associative learning?

A

Classical conditioning
- Occurs through the temporal pairing of stimuli
- The learning individual is passive and respondent i.e. the learning is an innate reflex

Operant conditioning
- Learning through learning the consequences of a response - an operation
- Here the individual is instrumental as they actively operate in the environment

Social learning theory:
- Combines both operant and classical conditioning and includes cognitive processes and a social interaction

Q

In classical conditioning with Pavlov’s dogs what is

a) Conditioned stimulus
b) Unconditioned stimulus
c) Unconditioned response
d) Conditioned response

A

a) Bell - it is conditioned as normally a bell does not illicit salivation

b) Food - food does not require conditioning to illicit salivation

c) UCR - salivation - occurs naturally

d) CR - refers to when salivation occurs following only the conditioned stimulus (bell)

The process of developing an association between conditioned stimulus and unconditioned response - acquisition

c) Simultaneous
d) Trace conditioning

A

a) CS (bell) appears first, then UCS (food) - both continue until salivation

b) UCS (food) appears first then the bell - doesn’t work with animals, used in advertising

c) Both CS and UCS come together - most common in real life

d) CS then removed and a pause before UCS presented - depends on a trace of the memory

Q

What did Rescoria show with regards to conditioning?

A

That predictiveness (i.e could you predict the nature of the UCS stimulus from the CS) is more important than temporal contiguity (< 0.5 ms)

For animals only awareness is needed for facilitation

Q

What is higher-order conditioning?

A

Using the conditioned stimulus (CS1) as the unconditioned stimulus for a second conditioned stimulus (CS2) - animals don’t respond higher than 4th order

40
Q

What does discrimination refer to with regards to conditioning?

A

Its the opposite of stimulus generalisation i.e. a child may only be afraid of dogs rather than all four legged or furry animals

41
Q

What is extinction?

A

Not loss of learning but loss of the behavioural response - occurs when the conditioned stimulus and unconditioned stimulus no longer pair of the reinforcer is no longer present

Spontaneous recovery is regaining a once lost response after some time

42
Q

How come latent inhibition prevent learning?

A

In classical conditioning if the conditioned stimulus has been previously exposed in an independent/isolated time then it may affect the pairing to the UCR

43
Q

What type of conditioning is used in systematic desensitisation and aversion therapy?

A

Counter conditioning - replacing a previously learned response with a desirable one

44
Q

Learning a behaviour because the right behaviour leads to desirable consequences refers to what type of learning?

A

Operant conditioning

45
Q

Who used trial and error learning experiments?

A

Thorndike - helped show operant conditioning

46
Q

How do reinforcement and punishment differ?

A

Reinforcement is aimed at trying to increase the frequency of a behaviour

Punishment tries to decrease the frequency of a behaviour

47
Q

Outline
a) positive reinforcement
b) negative reinforcement
c) positive punishment
d) negative punishment

A

a) Giving money for doing your chores
b) Not having to do the washing up if you tidy your room - remove an aversive stimulus

c) Hitting someone or points on license
d) Take away someones playstation - remove a positive item. Monetary fines included here as money is taken away

48
Q

Contrast and differentiate reinforcement schedules?

A

Continuous or contingency reinforcement - occurs after every positive response
Partial - only some of the positive responses result in positive reinforcement - depends on number of responses (ratio) or time (interval)

Fixed interval - any number of responses but reinforcement occurs after a defined interval
Variable interval - varying unit of time before reinforcement occurs - fishing

Fixed ratio - after twenty press ups I’ll sip on my drink/rest
Variable ratio - random number of responses before reinforcement - i.e, gambling

49
Q

In agoraphobia an individual avoiding places is known as?

A

Escape conditioning - a type of avoidance learning

50
Q

How do covert sensitisation and covert reinforcement differ?

A

Covert - imagined

Covert reinforcement - imagining the positive reinforcer i.e graduation to get one to study

Covert sensitisation - imagining punishment that may occur if bad behaviour is done - i.e. if keep drinking wife may leave be without a job

51
Q

What is successive approximation?

A

Also known as shaping occurs when a desirable behaviour is progressed to through successive reinforcement of behaviours that get closer to the target

i.e dog runs towards a wheel but doesn’t jump - gets a bone
dog runs and jumps towards but not through the wheel - gets a bone
dog jumps through the wheel - gets a bone

NOTE SHAPING IS USED WHEN THE BEHAVIOUR IS NOT YET PRESENT

52
Q

What is chaining?

A

Reinforcing a series of related behaviours which provide the cue for the next to obtain a reinforcer.

OCCURS WHEN THE BEHAVIOUR IS PRESENT BUT NOT IN THE CORRECT ORDER

i.e. linking letters wrote correctly in the right order - forward
or making a cake - starting with icing, then icing and baking - backward

53
Q

What is incubation?

A

Increase in strength if brief and repeated exposure of the stimulus - ie. rumination about anxiety-provoking stimuli

Maintains phobias and PTSD

54
Q

What is the process of unlearning a cue?

A

Fading

55
Q

Bandura came up with…

A

Social learning theory

Here social learning theorists felt individuals could learn a potential behaviour before doing it - behaviourists disagreed

56
Q

What is reciprocal causation?

A

An aspect of social learning theory that proposes the individual, the behaviour and the environment all influence each other

57
Q

Tolman’s cognitive learning refers to?

A

The fact that learning can take place without the learned response - i.e rats can make cognitive maps of mazes (place expectation) which encompass what they expect to arise before they actually are in them

Learning without performance - latent learning

58
Q

What is Gagne’s learning hierarchy?

A

Proposes that simple learning takes place earlier in development and other learning then follows

  1. Classical conditioning
  2. Operant conditioning
  3. Chaining
  4. Verbal association
  5. Discrimination learning
  6. Concept learning
  7. Rule learning
  8. Problem solving
59
Q

What is insight learning?

A

From Koher - very much opposed to associative learning and felt a learning is purely cognitive

60
Q

What is the cocktail party effect?

A

Being able to filter background/ground noise and perceive a stimulus i.e. our friends voice

61
Q

Depth perception depends on….

A

Non–pictorial (binocular) and pictorial cues

Non-pictorial - retinal image disparity, stereopsis, accommodation, convergence

Pictorial - size, brightness, superimposition, texture, linear perspective, aerial perspective, motion parallax

62
Q

When in a dark room and after a while a small, dim light appears as it is moving what can explain this?

A

Autokinesis - visual illusion

63
Q

What is phi-phenomenon

A

Perceptual illusion of perceiving moving images if still images are flicked together

64
Q

Name some theories of perception

A

Bottom up theory - e.g Gestalt we percieve a set of subsystems (emergent system) as a whole

Top down theory - Gregory - use prior information already known to form a hypothesis that allows sketchy retinal images to be formed

Perceptual set - The readiness to percieve selected features of an object depends on one’s motivation (hunger, beliefs, mood, context and expectations)

65
Q

Differentiate the terms selective/focussed attention and capacity or divided attention

A

Selective/focussed attention - mechanism by which certain information is registered whereas other irrelevant info is rejected - tested with dichotic listening task -> repeating messages said into one ear is shadowing

Divided/capacity attention is the maximum processing limit that can be performed on incoming information at one time –> dual-task technique (and individual has to attend and respond to all incoming messages)

66
Q

What is triesman’s attenuation theory?

A

That based on the semantic or physical characteristics messages are chosen to be processed fully or partially (the central executive weakens processing)

67
Q

How else is the pertinence model of attention known?

A

Deutch-Norman late selection filter model:
- Here all inputs are analysed at a high level
- Filtering only happens later

68
Q

How does pigeon holing expand Broadbent’s early model?

A

This refers to categorisation and that an individual may not filter on the basis of physical characteristics but semantic categories above other stimuli

69
Q

When we first learn piano this is under BLANK control however when we are more skilled automatic motor processes and attention can be directed to singing this is BLANK control.

A

Closed loop control - is the conscious attentional system

Open loop control - occurs when automatic processes take over. This is faster and means attention can be divided elsewhere

70
Q

Who proposed a hierarchical model of attention?

A

Sohlberg and Mateer. The hierarchical model of attention was based on how patients with brain damage sequentially recover.

71
Q

Name the 3 processes that occur with the formation and accessing of memories?

A

Encoding - formation of an initial memory trace and receives information from the outside

Storage - holding and maintaining information

Retrieval - access and recover information from stores

72
Q

What is the duration of short term memory storage?

A

15 to 30 seconds

or

7 +/- 2 items

Maintenance rehearsal and chunking can increase the capacity of STM

73
Q

Who divided LTM into declarative and non-declarative?

A

Tulving

74
Q

What is priming?

A

Information that is learnt without requiring conscious recall - form of implicit/non-declarative learning as it cannot be consciously inspected

75
Q

State the component’s of Baddley & Hitch’s model of working memory?

A

Phonological loop:
- Auditory rehearsal loops
- Dyslexia may be related to erratic phonological loop

Visuospatial sketchpad:
- Pattern recognition and movement perception components

Central executive:
- Capacity limited but modality free

Episodic buffer (added later):
- Multimodal store integrates information onto the LTM

76
Q

Name the two types of serial position effect?

A

Primacy - words first in a list remembered better. Thought to be due to consolidation to LTM occurs during the list

Recency - words at the end are remembered better. Last heard words are freshly retained.

Recency is better intact in those with anterograde amnesia - can’t form the transfer info from STM to LTM and/or retrieve from LTM.

Retrograde amnesia physically consolidated memories fail

77
Q

Name the three types of memory retrieval

A

Recognition

Recall - active and involves reproducing

Reintegration/reconstruction - recall based on partial cue. Not as accurate i.e. in eyewitnesses the account is influenced by the type of questioning

78
Q

Encoding specificity principle refers to?

A

The more similar the retrieval situation is to the encoding situation the better the retrieval

79
Q

Sudden onset anterograde amnesia with a retrograde amnesia for preceding days or week may make you think of?

A

Transient global amnesia - caused by temporary lack of blood flow to regions of brain concerned with memory function

80
Q

Where are the neural correlates of the phonological STM system in the brain?

A

L Broca’s areas and PFC

  • visuospatial STM is mediated by parietal and R prefrontal areas
81
Q

What is interference with regards to retrieval?

A

Piecing together easily accessible information - this is biased

82
Q

What is retroactive interference (in interference theory)?

A

When newly learnt information interferes with old material

  • Proactive interference refers to when new information being prevented from old material
83
Q

How do inductive and deductive reasoning differ?

A

Deductive - theory driven and top down:
- Theory - hypothesis - observation - confirmation

Inductive reasoning - bottom up and broader
- Observations = pattern - tentative hypothesis and theory

84
Q

What are the two broad types of problem solving?

A

Algorithmic:
- Time consuming done step by step to ensure a solution

Heuristics:
- Rule of thumb (Tversky and Kahenman)

85
Q

Outline what is meant by the following heuristic decision making processses

a) Representativeness bias
b) Availability heuristics
c) Base rate fallacy
d) Gambler’s fallacy
e) Sunk cost bias or entrapment
f) Anchoring-adjustment
g) Conjunction rule
h) Confirmation bias
i) Diagnostic momentum

A

a) Use stereotypical features to fit the problem into a well known category

b) Recent information available to the individual forms their decision

c) Assume a false positive than true positive in unlikely/rare events given their rarity

d) As an outcome has not happened in a while it should occur

e) Continuing with an action and feeling cannot withdraw as the cost that has happened is too great

f) Lock onto early features of a patient’s initial impression and use this to anchor later action plan/outcome ignoring later salient points

g) False belief that multiple reasons occuring together explain a presentation rather than one simple belief i.e. ocums razor

h) Using information that arises in a way to fit preconceived belief

i) Carrying on with a diagnostic label from a different clinician despite the belief that it could be incorrect

86
Q

Name the two dimensions of personality theories?

A

Situationalism (situation influenced) vs dispositional (personality is enduring and consistent)

Nomothetic (shared traits) vs. idiographic (unique traits)

87
Q

What are allport’s different traits?

A

Cardinal traits - influential, core traits that provide the ruling for individual’s behaviour and actions. Not everyone has them

Central traits: 5-10 which can be detected by others

Secondary traits: less influential only those close to the individual will be able to detect them - only arise in certain situations

88
Q

How does Cattell’s approach differ to Allports?

A

Cattell proposed there are surface traits that relate to each other but not fundamental to explaining personality but then there are source traits which are.

He came up with this through selecting 4,500 of Cattell’s words and reducing them to 171 elements to do factor analysis on - source traits formed 16 PF questionnaire.

3 types of data can reveal the categorical differences between normal and abnormal personality:
Q-data - questionnaires
L-data - life-time data
T-data - test date thematic apprerception test

89
Q

How did Eyesneck’s approach differ to Cattell’s

A

He had a dimensional view of personality and used second order analysis (orthogonal factor analysis) - Cattell used first order analysis

Both Eyesneck and Cattell believed in shared features (nomothetic) that were influenced by disposition

90
Q

What is Cloniger’s psychobiological model of personality?

A

Prpopesed four dimensions of temperament that manifest early in life (heritable) and 3 components of character (shaped by envinroment)

Temperaments:
- Novelty seeking
- Harm-avoidance
- Reward-dependence
- Persistance

Character dimensions:
- Self-directedness
- Cooperativeness
- Self-transcendence

91
Q

Name some projective tests of personality

A
  • Rorschach inkblot test - free association and inquiry phase - both analysed later and there is Exner’s system for scoring
  • Thematic apperception test (Murray - make a picture from the blank card)
  • Sentence completion test
  • Word-association test (Jung -time pressured)
  • Draw a person test
92
Q

Name some structured ways of assessing personality?

A

Q-sort technique - subject picks cards with labels that they feel describes them

International personality disorders examination
- Has self-report and screening quesitons
- Compatible with DSM and ICD
- Includes late onset or past personality disorder labels

Minnesota multi-phasic personality inventor:
- Self-report
- HAs ten scales with clinical labels
- 567 statements

93
Q

Outline Maslow’s 5 level and 7 level hierarchy needs

D needs - motives
B needs - growth/being needs

5: Self actualisation
4: Self-esteem
3: Belonging
2: Safety
1: Shelter

8: Transcendance
7: Self-actualisation
6: Aesthetic
5: Cognitive
4: Esteem
3: Belonging
2: Safety
1: Physiological

  • Note in this model levels 1-4 are D needs and levels 5-8 are B needs
94
Q

What is drive reduction theory?

A

Created by hull - if there is an imbalance in homeostasis this creates a psychological drive (arousal) to reduce the biological need

Primary drives are biological - hunger etc
Secondary drives are learned from primary - i.e power/self-esteem

95
Q

What us optimal discrepancy?

A

The strongest form of curiosity when information is different from what we know but not so dissimilar that it is strange or irrelevant

96
Q

What is cognitive consistence theory?

A

That dissonance created from cognitive inconsistencies drives us to correct the imbalance and make things consistent

97
Q

Compare and contrast the following theories of emotion

a) James-Lange

b) Cannon-Bird

c) Schacter-Singer labelling theory

d) Lazarus

A

a) Emotional perception depends on bodily (skeletal and visceral) changes. There is a feedback loop where the thalamus interpets the bodily signal and on the basis of this the emotion is labelled. A modification is the facial feedback where the thalamus interpret facial signals and perceives emotions accordingly.
