The Cognitive Approach
the main assumption of the cognitive approach is how we think is central in explaining how we behave and respond to different people and situations.

The Cognitive Approach-preferred method
Lab experiment, self report

Loftus and Palmer, Beck, Yochelson and Samenow

Loftus and Palmer 1st experiment
sample: 45 students shown 7 film clips of traffic accidents and asked to write an account of what they'd seen and answer specific questions, critical question asked about collision of vehicle words asked were smashed collided bumped hit contacted

increase incidence of schizophrenia in twins with biological parents. higher concordance rate in monozygotic than di zygotic twins not 100% concordance rate some environmental factors
23 of 92

posterior hippocampi significantly larger than those of control subjects and anterior hippocampal region was larger in control subjects, hippocampal volume correlated with the amount of timepositively right posterior and negative in right anterior
25 of 92
Individual Differences
The main assumption of the Individual Differences Approach is that their are differences between the people in any group in terms of their personal qualities and they ways in which they respond to certain situations.
26 of 92
Individual Differences-Preferred Method
Do not have a preferred method as they believe everyone is different adn the research method must be tailored to and individuals needs

33 of 92
McGrath Procedure
Lucy brought to session and constructed hierarchy of feared noises Lucy taught breathing and imagery to relax used fear thermometer to rate level of fear from 1-10, paired fear with relaxation then associated noise with feeling calm

The main assumption of the developmental approach is that how we change as we age in particular how we change cognitively and socailly within childhood effects our behaviour
36 of 92
Developmental-Preferred method

individuals conformed in one out of three occasions 32% conformity until stooge disrupts this and conformity drops to 5% majority bigger than three makes little difference

55 of 92
determinism states that all behaviours, mental acts and judgements are determined by factors out of our control
56 of 92
Free Will
Free will presents the view that our behaviour and mental acts are a results of our individual choices and volition
57 of 92
Determinism strengths
emphasis on cause and effect allowing us to change certain things. Determinism is the purpose and goal of science and objectivity. cause and effect relationships makes it more acceptable to society.
58 of 92
Determinism Weaknesses
Does not allow for free will, People can not be held accountable as behaviour was out of their control, removed responsibility, Determinism can never fully explain behaviour as it is often reductionist
59 of 92
Free Will strengths
People can be held accountable for their actions people more easily prosecuted, concious reflection of our behaviour allows us to achieve our goals and learn from our mistakes
60 of 92
Free Will weaknesses
Reductionist, people could be held accountable for things they can not be blamed for miscarriag of justice
61 of 92
Determinism Examples
physiological, behaviourist, psychodynamic soft determinism- developmental, social, cognitive and individual differences
62 of 92
reductionism is the process of explaining complex psychological phenomena by reducing them to their component parts or smaller simplistic factors
63 of 92
Holistic view looks at a person as a whole or perhaps looks at a complex of factors which explain a particular behaviour
64 of 92
Reductionism strengths
Breaks things down to its component parts allowing us to build them up again seen as a more scientifc and objective way cause and effect more applicable, easier to study one.
65 of 92
Reductionism weaknesses
Isolate factors does not always give a valid view of behaviour, components may be difficult to isolate and so manipulate hard to study it detached from wider social context.
66 of 92
Reductionism examples
physiological, behaviourist, social, psychodynamic, cognitive and developmental
67 of 92
Holism examples
Individual differences
68 of 92
the part of us that is genetically inherited
69 of 92
Refers to all our influences after birth, linking to environment and social context
70 of 92
Nature strengths
Scientific and objective can determine genetic risk factors and prevent them biological predispositions
71 of 92
Nature weaknesses
72 of 92
Nurture strengths
Allows us to discover that our behaviours are due to our learning and environment to create early prevention programmes
73 of 92
Nurture weakness
74 of 92
Nature examples
physiological, psychodynamic
75 of 92
Both nature and examples
Developmental, individual differences and cognitive
76 of 92
Nurture examples
Behaviourist and social
77 of 92
a situational explanation will look at a wider context of a persons behavioural factors including social group and physical environment
78 of 92
An explanation for an event that looks at individual characteristics and their traits and beliefs as an explanation for their behaviour
79 of 92
Situational strengths
early prevention programmes to prevent different social situations pens up new directions for further study into complex interraction
80 of 92
Situational weakness
Reductionist, can be difficult to separate effects, hard to investigate lowering ecological validity.
81 of 92
Individual strengths
evaluates free will
82 of 92
individual weaknesses
reductionist removes effect of environment
83 of 92

developmental and psychodynamic
85 of 92
individual examples
physiological, individual differences and cognitive

psychology as a science
It is a research based subject with investigation at its core, psychologists use scientific methods and carries out genuine experimentation through the manipulation and variables and controls it enforces, hypothesis empirically tested
87 of 92
Psychology is not a science
psychologies subject matter is humans can not be tested like chemistry and physics lack of objectivity environment effects it, much of what psychology investigates is emotion not genuine scientific and empirical data, no single theory or frame work
88 of 92
psychology as a science examples
physiological, behaviourist developmental
89 of 92
both is a science and isnt a science examples

psychology is not a science
