Cognitive assumptions
- Computer analogy.
- Schemata.
- Internal mental processes.
What is the computer analogy assumption?
Human mind works in similar ways to a computer. Receive input, process it, then output. Our senses work as an input, info stored, then retrieved when needed
Computer analogy example?
Atkinson and Shiffrin devised multi store model of memory. Suggested there are 3 stores of memory: sensory memory which involves input from senses. If pay attention info moves to short term. Rehearsing moves to long term.
What is the schemata assumption?
How our mind stores information in long term memory. Is not always factual
Schemata example
Halo effect suggests if our schema for an individual contains positive impressions e.g. if person friendly we believe they’re intelligent.
What is the internal mental processes assumption?
Humans use cognitive processes to make sense of the world around them. Use our senses to collect information from the outside world then use internal mental processes to interpret information.
Internal mental processes order
Attention, language, memory, decision making skills
Internal mental processes example
To study internal mental processes, psychologists use introspection where participant describes how task makes them feel.
What did Griffiths do
Griffiths asked participants to use introspection while gambling and found that regular gamblers have more irrational verbalisations.
Main components of CBT
- DYSFUNCTIONAL THOUGHT DIARY: write automatic negative thoughts and rate belief.
- COGNITIVE RESTRUCTURING: challenge dysfunctional thoughts outside of therapy and ask for evidence for them
- PLEASANT ACTIVITY SCHEDULING: pleasant activities everyday - behavioural activation technique.
Evaluation of CBT effectiveness POSITIVES
- RESEARCH SUPPORT: Cahill et al assessed severity of symptoms after each therapy session and 71% reduced symptoms.
- THERAPIST COMPETENCE: David and Avelno found CBT had highest success of all therapies.
- COMPARE DRUG THERAPY: Response rates both 58% so just as effective without side effects
Evaluation of CBT effectiveness NEGATIVES
- THERAPIST COMPETENCE: Kuyken and Tsivikos suggested 15% of all effectiveness may be due to therapist not therapy.
- INDIVIDUAL DIFFERENCES: Not suitable for everyone. Negative thinking may be caused by real stress.
Evaluation of CBT ethical issues NEGATIVES
- PATIENT BLAME: puts blame for illness on patient so reduces self esteem.
- RATIONAL THOUGHTS: up to therapist to decide what’s rational. It is subjective.
Loftus and Palmer methodology and procedures. EXPERIMENT 1
See if the speed estimates given would be influenced by wording. Shown 7 films of traffic accidents and asked to answer how fast car was going when they “hit, bumped, collided, smashed”.
Loftus and Palmer methodology and procedures. EXPERIMENT 2
150 participants shown car car. Asked to describe crash with different verbs and a week later asked if there was broken glass
Findings of Loftus and Palmer experiment 1
Verb and mean speed estimate: Smashed = 40. Hit = 34. Contacted = 32
Findings of Loftus and Palmer experiment 2
People who said yes: smashed=16. Hit=7. Control=6.
People who said no: smashed=34. Hit=43. Control=44
Ethical issues evaluation of loftus and palmer POSITIVE
BENEFITS SOCIETY - new developments in police questioning as they’re aware.
Ethical issues evaluation of loftus and palmer NEGATIVES
- UNRELIABLE EYEWITNESS TESTIMONY: wrongly convicted.
- DECEPTION: deceived in study and asked deliberately leading questions
- CONSENT: didn’t give fully informed consent. Not aware of research aims
Methodology and procedures evaluation Loftus and Palmer NEGATIVES
- SAMPLE ISSUES: only students so likely to share characteristics e.g. can’t drive.
- LACK OF ECOLOGICAL VALIDITY: staged videos. Respond differently in real life.
Methodology and procedures evaluation Loftus and Palmer POSITIVES
- RELIABLE RESEARCH: all watched same videos and same questions
- GOOD CONTROL OF EXTRANEOUS VARIABLES: order of videos changed so prevents order having effect. Laboratory.
Dream analysis main components
- DREAMS AS WISH FULFILMENT: unconscious fulfilment of wishes.
- SYMBOLIC NATURE: real meaning transformed into unharmful form
- DREAMWORK: use dreamwork to transform latent to manifest content
- ROLE OF THERAPIST: reverse the dreamwork process. Manifest into latent.
Effectiveness evaluation of dream analysis POSITIVE
RESEARCH EVIDENCE: Solms used PET scans to highlight regions of brain active in dreaming. Rational part inactive, money and motivation very active.
Effectiveness evaluation of dream analysis NEGATIVE
- METHOLOGICAL ISSUES: lack of ecological validity. Research into dreaming in sleep cabs so unnatural
- SUBJECTIVE INTERPRETATION: interpreting manifest and coming up with latent is subjective
