25
Theoretical model (cognitive approach)
Information processing, suggesting that information flows through sequences of stages = input, storage and retrieval (MSM).
26
Computer models
Mind compared to a computer, similar in information processing. (coding and use of stores) = artificial intelligence.
27
Schema
A mental framework of beliefs and expectations that influence cognitive processing - developed from experience.
28
The role of a schema
Enables info to be processed quickly like a mental short-cut, they can distort interpretations of sensory info.
29
Cognitive neuroscience
The scientific study of biological structures that underpin cognitive processes.
30
Paul Broca 1860's
identified how damage to the frontal lobe can impair speech production.
31
Advances in brain imaging
FMRI, PET scans allow access to the observation of mental processes. e.g. Long term memory and also the link between parahippocampal gyrus and OCD.
32
Evaluation of cognitive - scientific and objective methods
Highly controlled lab experiments = high internal validity. Allowed the emergence of biology and cognitive psychology, credible by science.
33
Evaluation of cognitive - Machine reductionism
Similarities between human brain and operations of computer, has been criticised as the computer doesn't feel emotions like humans can.
34
Evaluation of cognitive - Application to everyday life
cognitive sometimes too abstract an theoretical in nature. Often research on mental processes uses artificial stimuli = lack of external validity.
35
Evaluation of cognitive - Real-life application
Important contribution to to the field of artificial intelligence - thinking robots, revolutionise the future.
36
Evaluation of cognitive - less deterministic
Soft determinism recognises that we are free to think before responding to a stimulus.
37
Biological approach
emphasises the importance of physical processes in the body such as genetic inheritance and neural function.
38
What do Behaviour geneticists study?
whether behavioural characteristics such as intelligence, personality, and mental disorder etc. are inherited like eye and hair colour are.
39
Why are twins used to measure concordance rates?
They share the same or similar genes depending if they are identical or not.
40
What has been the finding of twin studies?
Monozygotic have higher concordance rates than dizygotic suggesting a genetic basis. MZ twins 100% and DZ 50% of genes shared.
41
What is the difference between genotype and phenotype?
genotype is their actual genetic make-up, whereas phenotype is the way genes are expressed through physical, behavioural and psychological characteristics.
42
Genotype
influenced by environmental factors on why they look different, one twin dyes there hair.
43
Phenotype
Even though twins have same genes they may express ones more than the other, causing them to be different.
44
Evolution
Charles Darwin = theory of natural selection - genetically determined behaviour that enhances survival an continue in future generations.
45
Evaluation of biological approach - scientific explanations of investigation
Uses scanning techniques e.g. FMRI's, EEGs, family + twin studies + drug trials. Accurate in measuring biological + neural processes not open to bias. Based on reliable data.
46
Evaluation of biological approach - Real-life application
Understanding of biochemical processes = development of psychoactive drugs that treat mental illnesses (depression). Sufferers can manage illness.
47
Evaluation of biological approach - causal conclusions
Explanation of mental illness using neurotransmitters. Lack of drug causes disorder, discovering association doesn't mean cause seen in biological approach.
48
Evaluation of biological approach - deterministic
Biological determinism, we are determined by biological causes = implication for legal system.
49
Evaluation of biological approach - Can't separate nature and nurture.
Focuses on family and twin genetic similarities. However, confounding variable in same environment so nurture as well as nature. Comparison of MZ and DZ twins.
50
The nervous system
specialised network of cells in the body that is the primary communication system, it responds to environment and coordinates workings of organs and cells.
51
Central nervous system
made up of brain (highly developed cerebral cortex makes us different to animals) and spinal cord =extension of the brain, responsible for reflexes.
52
Peripheral nervous system
transmits messages via millions of neurons to CNS, it is subdivided into Autonomic and Somatic nervous system.
53
Autonomic nervous system
transmits info to and from organs, operates involuntarily, governs breathing, heart rate etc.. 2 divisions - sympathetic and parasympathetic.
54
Somatic nervous system
controls muscle movement and receives info from sensory receptors, sends to CNS
55
endocrine system
instructs glands to release hormones into bloodstream to go to target organs. e.g. thyroid gland produces thyroxine that increases heart rate and metabolic rates.
56
What is known as the 'master gland' located in the brain?
Pituitary gland - controls and releases hormones from all endocrine glands in the body.
57
Fight or flight
ANS changes from para to sympathetic influencing adrenaline to be released by adrenal medulla. This causes increased heart rate as soon as threat is detected.
58
What happens after fight or flight response?
Parasympathetic returns to state acting as a 'brake' reducing activities of the body caused by the response.
59
Three types of neuron
Motor, sensory and relay.
60
structure of neuron
cell body includes nucleus dendrites protrude from cell body. Axon carries impulses away from cell covered in myelin sheath protecting electrical message. Nodes of ranvier quicken process jumping pulses. terminal buttons communicate neuron across synapse.
61
Electric transmission
neuron resting = -ve charged. Activated by stimulus inside cell thats +ve causing an action potential. Causes electrical impulse travel down axon to end of neuron.
62
Chemical transmission
Neurons communicate via neural networks. Signals within neuron electric, signals between neuron chemical. when reach end of neuron neurotransmitter releases in tiny sacs called synaptic vesicles.
63
Neurotransmitter
Crosses gap taken by postsynaptic receptor site and converted back to electrical. Each neuroT has its own specific molecular structure that fits like lock and key.
64
What does the neuroT Acetylcholine do?
found at each point where a motor neuron meets a muscle, causes the muscle to contract.
65
Excitation
when a neuroT increases the +ve charge of postsynaptic neuron. Increase likelihood of neuron passing on electric message. (adrenaline)
66
Inhibition
When a neuroT (serotonin) increases -ve charge of postsynaptic neuron. Decreases likelihood of neuron passing on electric message.
67
Psychodynamic approach
Describes the different forces, most of which are unconscious, that operate on the mind and direct human behaviour and experience.
68
The unconscious
A part of the mind that we are unaware of but which continues to direct much of our behaviour.
69
Preconscious
Between conscious and unconscious includes thoughts and ideas which may become aware in dreams.
70
Id
unconscious made up of selfish aggressive instincts that demand immediate gratification. Only one present at birth.
71
Ego
Reality principle balancing the conflict demands of id and superego. Develops at age 2.
72
What are the defence mechanisms used by the ego?
Repression, Denial and displacement.
73
Superego
Moralistic part of our personality which represents the ideal self. Formed at the end of the phallic stage.
74
What are the psychosexual stages.
``` Oral 0-1yrs Anal 1-3yrs Phallic 3-5yrs Latency Genital ```
75
what happens if psychosexual stages are unresolved?
Child becomes fixated with the stage and stuck carrying behaviours and conflicts through to adulthood.
76
Evaluation of Psychodynamic - Explanatory power
Huge influence on psychology. Used to explain personality disorder, abnormal behaviour etc. Draws attention to behaviours and relationships in adulthood.
77
Evaluation of psychodynamic - Case study method
Freuds research based on study of individuals often in therapy. His interpretations were highly subjective (little hans). Methods lack scientific rigour.
78
Evaluation of psychodynamic - Untestable concepts.
Karl Popper argued approach doesn't meet scientific criterion of falsification . Unconscious level we can't test. Popper = pseudoscience aka fake.
79
Evaluation of psychodynamic - Practical application
Brought new forms of therapy - hypnosis. Forerunner to many psychotherapies. Also seen as harmful and inappropriate for those suffering mental disorders.
80
Evaluation of psychodynamic - Psychic determinism
No such thing as an 'accident'. Slip of the tongue. All behaviour as determined by the unconscious. Ignores free will.
81
Humanistic approach
emphasises the importance of subjective experience and each person's capacity for self-determination.
82
Who are the Humanistic psychologists?
Rogers and Maslow
83
Free will
Humans can make their own choices and are not determined by biological or external forces.
84
Self-actualisation
The desire to grown to fulfil one's full potential. It is the uppermost level in Maslow's hierarchy of needs. To reach this you have to go through the lower levels.
85
What are Maslows hierarchy or needs?
Physiological needs, Safety and security, love and belonging, self-esteem and self-actualisation.
