Approaches Flashcards
Introspection
First attempt to examine one’s own thought processes
Standardised instructions
The instructions given to each participant are kept identical - to help prevent experimenter bias.
When was Wundt’s lab established?
1879
Genotype
An organism’s genetic makeup, or allele combinations.
Phenotype
The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Concordance rates - MZ
100%
Concordance rates - DZ
50%
Genetic Tests
reveals an individuals genotype, but will only show whether a person has predispositions to developing a specific conditions
Evolution
Genes have adapted to become useful to our survival and are passed onto offspring
Nervous System
System of nerves which allows you to register touch, move, breathe, feel and think. Made up of neurons
Central Nervous System (CNS)
consists of the brain and spinal cord
Neurochemistry
Relating to chemicals in the brain that regulate psychological functioning
Neurotransmitters
Chemical messengers, across the synapse, bind with receptors
BA: Supporting Evidence (Strength)
Lots of supporting evidence; supports the assumption that genetics are involved in causes of behaviour because when there is a higher proportion of genes shared, the disorder is MORE likely
BA: Practical Applications (Strength)
Real-life applications to support the approach. This means that there is evidence for the biological basis of some disorders.
BA: Correlational Data (Weakness)
Correlation between neurotransmitter levels and mental disorders. This means it is only a relationship. Cannot be concluded that neurotransmitter levels cause the behaviour.
BA: Contradictory Evidence (Weakness)
Concordance rates in twin studies are never 100%. This suggests that behaviour is not purely genetic. Approach fails to recognise the role of the environment on behaviour.
BA: Deterministic View (Weakness)
Suggests no conscious control over human behaviour. This means that individuals do not have free will over their behaviour.
Classical Conditioning (Pavlov)
learning occurs through the pairing of a neutral stimulus and an unconditioned response that produces an automatic response.
Operant Conditioning (Skinner)
assumes that behaviour is based on learning through consequence.
3 Consequences (OC)
1) Positive Reinforcement - behaviour is MORE LIKELY to occur due to positive consequences 2) Negative Reinforcement - behaviour is MORE LIKELY to occur due to negative consequence 3) Punishment - behaviour is LESS LIKELY to occur because of the negative consequences
variable-ratio schedule
In operant conditioning, a reinforcement schedule that reinforces a response after an unpredictable number of responses
BEA: Scientific Methods (Strength)
Focuses on observable behaviour within controlled settings. This means it was an influential approach in the development of psychology as a science.
BEA: Real-life Applications (Strength)
Principles of conditioning have been applied to real-world behaviours. This means the approach has led to therapies to treat disorders.
BEA: Use of Animal Research (Weakness)
Lack of validity due to differences in physiology/brain structure. This means findings may not generalise to humans as thought processes are underestimated
BEA: Lack of Biology (Weakness)
Emphasis is on environmental factors affecting behaviour. This means it is not a complete approach
BEA: Deterministic Approach (Weakness)
Emphasis on environmental factors affecting behaviour. This means the approach views free will as an ‘illusion’. Suggests no conscious control over behaviour.
Social Learning Theory
Bandura believed people learnt behaviour in a social context through observation of other people and the reinforcement or punishment they receive.
Stages of Social Learning Theory
Identification, Modelling, Vicarious Reinforcement
Identification
Observer associates themselves with a role model because they idolises them and their behaviour
Modelling
the process of observing and imitating a specific behaviour
Vicarious Reinforcement
Imitation is more likely to occur if the model is positively reinforced for their behaviour
Mediational Processes
Attention: The extent to which we are exposed/notice the behaviour. Retention: How well the behaviour is remembered. Reproduction: This is the ability to perform the behaviour that the model has just demonstrated. Motivation: The will to perform the behaviour.
SLT: Supporting Evidence (Strength)
Supporting evidence from controlled research that demonstrates social learning occuring
SLT: Focus on Cognitive Processes (Strength)
Emphasises role of mediational processes. This means the approach suggests people have more free will over their behaviour.
SLT: Cultural Differences Accounted For (Strength)
Explains differences observed across different cultures. This adds credibility to the theory as an explanation of human behaviour.
SLT: Unrealistic Evidence (Weakness)
Lacks ecological validity due to the controlled environment. This limits the conclusions that can be drawn about social learning in the real-world
SLT: Biological Roles Ignored (Weakness)
Emphasises environmental impact. Doesn’t account for biological factors eg. gender difference. This means it is not a complete explanation for behaviour.
