Approaches in psychology Flashcards
What is significant about Wilhelm Wundt?
He established psychology as a science in a laboratory, he called himself a psychologist
What is introspection?
Introspection involves reflection on your own conscience and reporting present experiences
How might introspection be tested?
Through displaying an object and analysing their reactions and sensations
What assumption is made of classical conditioning?
That behaviour is acquired through learning and association
Who is the key theorist for classical conditioning?
Ivan Pavlov
What is Pavlov’s experiment?
Food presentation and salivation. The bell was the neutral stimuli
Before conditioning
UCS = UCR
During conditioning
UCS + NS = UCR
After conditioning
CS = CR
What is contiguity?
The presentation of one stimuli with another
Who is the key theorist for operant conditioning?
Skinner
What is operant conditioning?
A way of learning through positive and negative consequences
How did Skinner study positive reinforcement?
- Rat in box
- As rat moved it would accidentally hit lever
- This released pellet of food
After multiple times the rat knew to go straight for the lever
How did Skinner study negative reinforcement?
- Rat in box
- Electric current passed through causing discomfort
- Lever switched off current
Rat learned to go straight for lever
What are 3 strengths of CC and OP conditioning?
- use of empirical and experimental methods
- CC has led to the development of therapies
- OP is used as a behavior modification technique (schools etc.)
What is a weakness of CC and OP conditioning?
The use of animals in research is not good because different species have different survival needs. Humans have consciousness and free will so they have the ability to resist conditioning
What is the social learning theory?
Bandura believed that behavior was not only acquired through direct experience but through observation and imitation of others
What is a live model in the SLT?
Might be a parent, teacher etc.
What is a symbolic model in the SLT?
Someone portrayed in media
When is the SLT more effective?
When observers identify with the model
What is vicarious reinforcement?
Learning that is not a direct reinforcement of behavior, but through observing someone else being reinforced for that behaviour
What is meant by the meditational process?
Internal mental processes that exist between environmental stimuli and the response from the individual to those stimuli
What experiment did Bandura use to show the social learning theory?
(Bobo doll)
Children who observed aggressive and non-aggressive adult models and were then tested for imitative learning in the absence of the model
What is a strength of the social learning theory?
Useful applications such as criminal behavior.
Criminal behavior might increase when exposed to models who show this
What is a limitation of the social learning theory?
Disregards other potential influences on behavior
What is the biological approach to psychology?
Assuming that human behaviour can be explained by recognising that psychological was first biological. It is the concept that the ‘mind’ resides in the brain so thoughts, feelings and behaviour ultimately have a physical basis
What are 2 strengths of the biological approach?
- Empirical and scientific methods so results are often reliable
- Helped to find treatments for a variety of psychological disorders
What are 2 weaknesses of the biological approach?
- Disregards other influences
- Characteristics could be copied from parents through SLT not genetics
- Problems w evolution as an explanation
What is the genotype? (Biological approach)
The genetic code that is written in the DNA of individual cells
What is the phenotype? (Biological approach)
The physical appearance and expression of genes in behavior that results from inheritance
What might happen if people had low levels of serotonin?
Display increased aggression
What is serotonin associated with?
Maintaining a stable mood
What are the 3 parts to the biological approach?
- Genetic basis
- Neurochemistry
- Evolution
