Q

What is introspection?

A

Mental processes can be studies systematically as they occurred
Eg participants shown object like metronome and asked to describe their inner processes
Stimulus is always the same and controlled

Q

Criticisms of introspection

A

not reliable- unobservable
researchers observed diff things
other psychologists already produced theories you can easily generalise
unreliable- participants unaware of factors influencing them

Q

A

watson criticized it as was subjective so behaviourism and scientific science came about

Q

assumptions of scientific approach

A

behavior is seen as being caused (assumption of determinism)
if behavior is determined, should be able to predict it in diff conditions (assumption of predictability)

Q

What is the scientific method?

A

the use of investigative methods that are objective, systematic and replicable
dont let preconceived ideas influence
replicable and reliable
measurement of empirical data carried out accurately with consideration of other factors

9
Q

+ and - of scientific method

A

+
relies on objective and systematic methods
rely on belief in determinism so can establish causes through replicable methods
scientific theories dont fit facts anymore, can be refined /abandoned
-
objective and controlled so not very ecologically valid
lots of subject matter is unobservable so lack accuracy
not all psychologists think behaviorism can be studied scientifically

Q

Basic features of psych as a science

A

controlled, experimental conditions show cause and effect and test hypotheses
highly standardized- reliable
use of iv and dv
objective, systematic, replicable
build and refine and falsify theories

Q

what is behaviorism?

A

believes psych is study of behavior not mind
scientific as can study directly
all behavior is learnt through conditioning

Q

Describe the study on classical conditioning- dogs

A

1902 pavlov’s dogs
dogs taught to associate bell with food so began to salivate
Ucs- object or event that produces reflexive action
ucr- response to ucs
ns- neutral stimulus doesnt produce response
cs- ns associated with ucs
cr- response to cs

Q

describe the study on classical conditioning- little albert

A

Watson and Rayner 1920 induced fear of white rats in little albert
before: ns is rat, ucs is bang, ucr is cry
during: ns+ucs=ucr
after: cs=cr

15
Q

+ and - of little albert study of classical conditioning

A

+
practical applications- devise treatment to maladaptive behavior
reliable- highly controlled
-
ethics- albert couldn’t consent or withdraw
generalizability- small sample
ecological validity- too controlled

Q

what is operant conditioning? who came up with/ developed it?

A

behaviour is shaped through reinforcement
developed by BF Skinner but based on Thorndike’s laws of effect

17
Q

positive reinforcement

A

strengthens behaviour (more likely to repeat) by providing rewarding consequence
skinner showed this by placing rat in skinner box with lever, rats bumped into it and food dropped. rats learned to go straight to lever

18
Q

negative reinforcement

A

strengthens behavior (more likely to repeat) by removing unpleasant reinforcer

skinner showed this by placing rat in box and giving it shock. as it bumped into lever, turned off so leant to go to it straight away. light just before shock-learned to press lever as shock was coming

19
Q

what is a neutral operant?

A

response from environment that neither increases or decreases probability of decreasing behaviour

20
Q

punishment

A

weakens behaviour (less likely to repeat)
can directly apply unpleasent stimulus or remove rewarding one

21
Q

problems with punishment

A

behaviour suppressed not forgotten-returns when punish goes
increased aggression- shows its coping mechanism
creates fear that can generalise eg dont want to go to school
doesnt guide to correct behaviour

22
Q

unpredictable reinforcement

A

gave rat pellet every 5 lever presses- more effective

23
Q

+ and - of operant conditioning

A

+
practical applications- treatments eg for phobias
scientific method- reliable and controlled
-
based on animals not humans-free will
reductionist- doesnt take nature into account

24
Q

what is social learning theory?who introduced it and when?

A

learning through imitation
introduced by bandura in 1960s and his bobo doll study

25
describe banduras study
Children in groups with agressive or calm adult and a bobo doll Children taken to room where can’t play with toys- annoys them Then get to bobo doll and play Agressive children more likely to be agressive and verbally agressive wherrr as no from calm group were verbally aggressive Girls more likely to imitate girls etc Repeated 4 months later and agressive group still agressive
26
what are the 5 processes to learn behaviour?
Modelling- example of behaviour Identification- how much they relate Imitation- more rapid than conditioning Vicarious reinforcement- see someone else being rewarded Role of meditational processes-
27
what are the 4 mediational processes?
Attention Retention Reproduction Motivation
28
+ and - of SLT
+ Practical applications- study shows more likely to commit crime if exposed Research support- bandura - Problems with causality Reductionist- disregards genetics
29
what is the cognitive approach? problem?
All behaviour is proceeded by a thjught which can be studied scientifically Howver can only study through introspection and inference
30
what is the computer analogy? criticisms?
Brain works in same way as computer Info taken in from senses, processes and output is behaviour Machine reductionist Models are incomplete
31
What is schema theory?
All knowledge is organised into sub units Help us organise and interpret info so allows shortcuts Help us fill gaps but cause stereotypes
32
Bartlett’s war of the ghosts showed participants distorted story in three ways
Assimilation-story became in line with participants cultural expectations Levelling- story became shorter each retelling Sharpening- changed story to make sense to them using diff terms etc
33
According to Piaget:
We try to understand new and different things using pre existing schemas During assimilation we try to fit new things into existing schemes During accommodation we change schemas to fit characteristic of new object(learning)
34
Why is cognitive neuroscience better than other methods?
Can look at healthy brains Can accurately map function
35
what is cognitive neuroscience?
the scientific study of brain structures that are responsible for cognitive processes. explores neurological basis of thought processes and disorders
36
What are fMRI, PET scans, lesion studies?
FMRI- scanning technique pinpoints area of brain active PET scans- radioactive drug in blood can see where goes- more active parts Lesion studies- look at people with brain damage
37
Practical applications of cognitive neuroscience
Study mental processes in people with depression ocd dyslexia Help decide on rehabilitation programmes (woman with stroke now better) Deeper knowledge of causes of disorders and treatments Shows brain plasticity Early identification for cognitive problems so can help treat before observable behaviour
38
+ and - of cognitive approach
+ Practical apps eg understanding behaviour Scientific eg reliable - Limitations of computer model eg forgetting things Lacks external validity- inferred, artificial stimuli
39
Assumptions of biological approach
Views humans as biological organisms All behaviour has a biological cause Interested in genetic issues Study role of hormonal and chem changes Nature not nurture Interested in Charles Darwin’s ideas
40
What are mz and dz twins? What are concordance rates?
Mz- 100% same genes Dz- 50% same genes Concordance rates- % of both twins displaying same characteristics
41
Gottesman and shields study on twins
1972 58% concordance for mz and 12% for dz for schizophrenia Higher for mz as share mkre but not 100% so other factors
42
What are genotype and phenotype?
Genotypes- genetic code written into DNA Phenotype-physical appearance of that Don’t always coincide eg genotypes for blue eyes but have brown as dominant Illness can also affect it Mz have same genotype but environmental factors can affect phenotype
43
Describe evolutionary theory Examples criticisms
Organisms become adapted over time through natural selection and survival of the fittest Peppered moth Bowlby- attachment to care giver for food Buss- mate choices evolved for reproductive success But Why don’t all organisms evolve at same rate? Why to apes still exist
44
+ and - of biological approach
+ Scientific so valid and reliable Practical app eg treat hormones with drugs - Reductionist Issues with evolutionary theory Determinism- no free will and can’t control so crime become biological fault
