approaches Flashcards
Who was Wilhelm Wundt and what did he do?
-In 1873 Wilhelm Wundt published the first book on psychology ‘Principles of Physiological Psychology’
-in 1879 opened the first psychology laboratory in Leipzig, Germany.
-He is often considered to be ‘the father of psychology’
- his approach became known as structuralism.
-established psychology as a science by using the scientific method
what is structuralism?
study of the structure of the human mind, by breaking down behaviours into their basic elements,
what are the three components of structuralism?
-Thoughts
-Images
-Sensations
What did Wundt use to investigate the human mind?
introspection
what is introspection?
A systematic experimental attempt to study the mind by breaking up conscious awareness into basic structures of thoughts, images and sensations
What were the two major assumptions Wundts new scientific approach was based on ?
-All behaviour is seen as being caused (determined)
-If behaviour is determined, then it should be possible to predict how human beings would behave in different conditions (predictability)
The scientific method refers to the use of investigative methods that are…
-Objective (factual)
-systematic (controlled)
-replicable (or standardised procedures)
evaluation of introspection
-Introspection relies primarily on non-observable responses and although participants can report conscious experiences, they are unable to comment on unconscious factors relating to their behaviour.
-Introspection produced data that was subjective (varied greatly from person to person), so it became very difficult to establish general principles.
Behaviourist approach
a way of explaining behaviour in terms of what is observable and in terms of learning.
what did the behaviourist approach reject?
introspection
key assumptions of the behaviourist approach
-We are born as “blank slates”
-All we have at birth is the capacity to learn
-All behaviour is learned from the environment
-Focus of the approach: observable behaviour
the behaviourist approach is only interested in studying behaviour that can be …
observed and measured
classical conditioning
learning by association and refers to the conditioning of reflexes and involves associating a new stimulus with an innate bodily reflex
Who demonstrated classical conditioning?
Pavlov
the formula for classical conditioning
UCS = UCR
Unconditioned stimulus = Unconditioned response
UCS + NS = UCR
Unconditioned stimulus + neutral stimulus = Unconditioned response
CS = CR
Conditioned stimulus = Conditioned response
the formula for classical conditioning (dog and bell example)
UCS = UCR
Food = salivation
UCS + NS = UCR
Food + bell = salivation
CS = CR
Bell = salivation
operant conditioning
A form of learning in which behaviour is shaped and maintained by its consequences.
name the three consequences (operant conditioning)
-Positive reinforcement
-Negative reinforcement
-Punishment.
what is positive reinforcement?
Involves receiving a reward when a certain behaviour is performed.
what is negative reinforcement?
Occurs when an animal/human avoids something unpleasant.The outcome is a positive experience, so they will do it again.
what was the skinner box experiment?
-showed how negative reinforcement worked
-placed a rat in his box and then subjected it to an unpleasant electric current which caused it some discomfort.
-As the rat moved about the box it would accidentally knock the lever. -electric current would be switched off.
-The rats quickly learned to go straight to the lever after a few times of being put in the box.
-The consequence of escaping the electric current ensured that they would repeat the action again and again.
Evaluation 1- well controlled research (behaviourist approach)
-strength
-its based on well controlled research
-behaviourists focused on the measurement of observable behaviour within highly controlled lab settings
-by breaking down behaviour into basic stimulus-response units, all other possible extraneous variables were removed allowing cause and effect relationships to be established
-e.g. skinner was able to clearly demonstrate how reinforcement influenced an animals behaviour
-suggests that behaviourist experiments have scientific credibility
Evaluation 2- Counterpoint of well controlled research (behaviourist approach)
-weakness
-behaviourists may have oversimplified the learning process
-behaviourists ignored an important influence on learning- that of human thought
-other approaches have drawn attention to the mental processes involved in learning
-suggests that learning is more complex than observable behaviour alone
evaluation 3- real world application ( behaviourist approach)
-strength
-principles of conditioning have been applied to real world behaviours
-operant conditioning has been used in institutions such as prisons and psychiatric wards
-they reward appropriate behaviour with tokens that can be exchanged for privileges
-this increases the value of the behaviourist approach because it has widespread application
evaluation 4- environmental determinism (behaviourist approach)
-limitation
-sees all behaviour as conditioned by past experiences
-skinner said that everything we do is the sum total of our reinforcement history
-this ignores any possible influence that free will may have on behaviour
-this is an extreme position and ignores influence of conscious decision making processes on behaviour
what is social learning theory
A way of explaining behaviour that includes both direct and indirect reinforcement, combining learning theory with the role of cognitive factors
what is vicarious reinforcement?
reinforcement which is not directly experienced but occurs through observing someone else being reinforced for a behaviour. This is a key factor is imitation.
what are the 4 mental or mediational processes in learning identified by bandura ?
-attention
-retention
-motor reproduction
-motivation
what is attention?
the extent to which we notice certain behaviours
what is retention?
how well the behaviour is remembered
what is motor reproduction?
the ability of the observer to perform the behaviour
what is motivation?
the will to perform the behaviour, which is often determined by whether the behaviour was rewarded or punished
what is imitation?
copying the behaviour of others.
what is identification?
when an observer associates themselves with a role model and wants to like the role model.
what is modelling?
imitating the behaviour of a role model.
Bandura (1961) Bobo doll study
-lab experiment
-Sample: American children, 36 boys and 36 girls aged between 3-6 years old .
-Group 1: 12 girls and 12 boys were shown a model hitting the doll with a hammer and shouting at the doll.
-Group 2: 12 girls and 12 boys were shown a model shown a non-aggressive model.
-Group 3: 12 girls and 12 boys (control group) were not shown a model.
results for the bobo doll study
-The children who had observed the aggressive model (group 1) were more aggressive than the children from the other two groups.
-Group 1 imitated specific aggressive acts that were displayed by the model.
-Boys imitated more physically aggressive acts than girls.
-There was no difference in the verbal aggression between boys and girls.
Negative evaluation of Bandura’s study
-Setting and behaviour of adults was strange/artificial (demand characteristics).
-Bobo dolls are designed to be hit – this may have caused the observed effects (validity).
-Possible long term effects on participants (ethics)
Positive evaluation of Bandura’s study
+Continuity- each child exposed to same environment (control)
+Replication (and subsequent studies)
evaluation 1- cognitive factors ( SLT)
-strength
-recognises importance of cognitive factors in learning
-from observing others one forms an idea of how new behaviours are performed and on later occasions this coded info serves as a guide to action
-suggests SLT provides a more comprehensive explanation of human learning due to mediations
evaluation 2- counterpoint to cognitive factors ( SLT)
-weakness
-makes little reference to biological factors on social learning
-Behaviour in Bandura’s research may be a result of mirror neurons in the brain that allow us to empathise with and imitate other people
-suggests that biological influences on social learning were under-emphasised in SLT
evaluation 3- contrived lab studies (SLT)
-weakness
-evidence gathered through lab studies
-there is contrived nature in lab studies where participants may respond to demand characteristics
-purpose of a bobo doll is to strike it so children were behaving in a way that they thought was expected
-suggests that this research may tell us little about how children actually learn aggression
