Approaches into Psychology Flashcards
Wundt’s Introspection
Where a ppt is given a stimulus, and is then trained to recall all their thoughts to do with this stimulus.
- Involves examination of one’s thoughts
What did Wundt do?
Separated psychology as a science from philosophy, physiology, and biology.
- Founded first psychology lab in Germany
Theory of Structuralism
Studying the structure of the mind through introspection or internal reflection
What are the main 5 Behaviourist Assumptions
- Most behaviour is learnt directly (except innate reflexes)
- Behaviour depends on its consequences
- Animals and humans learn the same way
- The mind is irrelevant
- The key form of learning is Conditioning
Unconditioned
Regular act/response before conditioning (unlearnt)
Conditioned
A learnt act in response to a stimulus which isn’t regularly associated
Stimulus
Cause of a response/act, can be un/conditioned
Association
Correlating a stimulus to a response
Reinforcement
Something to increase the likelihood of an action/behaviour being repeated
Positive Reinforcement
Receiving a reward to increase likelihood of an action/behaviour being repeated
Negative Reinforcement
Acting to avoid something unpleasant to increase likelihood of repetition
Punishment
Unpleasant consequence of behaviour to reduce likelihood of repetition
Operant Conditioning
Learning through reinforcement & consequences
Classical Conditioning
Learning through association
Pavlov’s experiment
Studied salivation in dogs as an expectant response to being fed, through using a small tube in the dog’s cheek which measures the amount of saliva produced.
- NS (bell) -> No Response / UCS (food) -> UCR (saliva)
- NS + UCS -> UCR
- CS (bell) -> CR (saliva)
Strengths of Behaviourism
- Uses controlled lab experiments (pavlov/skinner, scientific credibility)
- Has real life application (understandings for treatments for phobias & addictions - token ecomomy)
Limitations of Behaviourism
- Deterministic (very little free will as only env. shapes behaviour)
- Reductionist (ignores other factors like hormones)
- Nature/Nurture (ignores bio as it’s nurture)
Social Learning Theory
Believes behaviour is learnt from social environment through observation and imitation
Vicarious Reinforcement
The frequency of certain behaviors increases as a result of observing others rewarded for the same behaviors
Modelling
Individuals learn a particular behaviour through observing a model performing that behaviour
Imitation
Action of using someone or something as a model and copying their behaviour
Identification
Form of influence where an individual adopts an attitude/behaviour in order to be associated with a particular group/person
Mediational Processes
The internal mental processes that exist between environmental stimuli and the response made by an individual to those stimuli
What are the 4 Mediational processes?
Attention
Retention
Motor Reproduction
Motivation
Attention
The extent to which we notice certain behaviours
Retention
How well the behaviour is remembered
Motor Reproduction
The ability of the observer to perform the behavior
Motivation
The will to perform the behaviour,which is based of whether the behaviour was rewarded or punished
Strengths of SLT
- Cause & Effect as it uses scientific methods
- Real Life Application (contributed to understandings of aggression and gender development & formed basis for phobia treatments)
- Explains a large number of behaviours & a range of processes
Limitations of SLT
- Overrelies on evidence from lab studies that lack ext. validity
- Punishments/rewards are subjective so may be individual differences
- Lacks population validity as BOBO DOLL uses ppts from one location (stanford uni)
Cognitive Approach
Focuses on how internal mental processes affect behaviour
Schema
A cognitive framework that helps to organise and interpret incoming information in the brain
Inference
Reaching a logical conclusion based on evidence and reasoning
Reasons Schemas aren’t useful
- Contribute to negative stereotypes & make it difficult to retain new info that don’t fit preestablished ideas
- Schemas develop in childhood & are usually resistant to change
- If left unmanaged, they can cause negative patterns that are inforced by unhealthy interactions
- Once a schema is developed, it can unconsciously influence your thoughts & actions
Reasons Schemas are useful
- Help predict what will happen happen in the world based on our experiences
- Enable us to process vast amounts of information rapidly
- Prevent us from becoming overwhelmed by environmental stimuli
Strengths of Cognitive Approach
- The methods are highly controlled
- The approach is used w/ cognitive neuroscience so it has practical and theoretical applications
- Soft deterministic
- Takes into account unobservable processes
Limitations of Cognitive Approach
- Dependent on controlled experiments, so lacks ecological validity & mundane realism
- Subjective as unobservable processes can only be inferred
- Doesn’t consider genetics
- Machine Reductionism: comparing humans to machines ignores emotional and motivational factors
Theoretical Models
- Simplified representations of cognitive processes based on current research evidence
- Often are incompltete & are frequently changed, updated, and refined
Computer Models
- The process of using computer analogies as a representation of human cognition
- Development of computers and computer programming led to interpret the way sensory information is coded as it passes through the system
- information is inputted through senses, encoded into memory & then combined with previous information to complete a task
Cognitive Neuroscience
An area of psychology dedicated to the underlying neural basis of cognitive functions
What do Cognitive Neuroscientists do?
They are able to study the brain and collct detailed information about the brain structures involved in different kinds of mental processing
Phenotype
Characteristics that form a group
