Approaches in Psychology (Origins, Behaviourist, SLT, Cognitive)- TB Flashcards
O: What is knowledge?
Information that we already have or can gain
O:What is evidence?
Proof that supports or criticises a hypothesis or knowledge
O: What was Wilhelm Wundt’s aim?
To study the structure of the mind by breaking down behaviour to basic elements (Structuralism) by using introspection
O: What is empricism?
A belief that knowledge is gained through experience
O: What is introspection?
The process by which a person gains knowledge about their own emotional state by noting conscious thoughts & feelings
O: What is scientific method?
Refers to use of investigative methods that are objective, systematic & replicable
O: What is structuralism?
Breaking down behaviour into its basic elements
O: How did Wundt formulate general theories of human perception?
Using introspection and training their mental processes
O: What 3 things does the scientific method refer to investigations as being?
1) Objective
2) Systematic
3) Replicable
O: What are two assumptions that the scientific approach is made on?
1) Determinism- all behaviour has a cause
2) Predictability- it is possible to predict behaviour in different conditions
O: What is an objective investigation?
Researchers don’t let preconcieved data or biases influence the collection of their data
O: What is a systematic investigation?
Observations or experiments are carried out in an orderly way
O: What is a replicable investigation?
Observations can be repeated by other researchers to determine whether the same results are obtained- helping reliability
O: What are 2 criticisms of Wundt’s research?
1) Not reliably reproduced by other researchers
2) Relied on non-observable responses e.g. memory
O: How do Nisbett & Wilson (1977) challenge introspective reports?
They claim we have very little knowledge of the causes of and process underlying our behaviour & attitudes- so people are unaware of what’s influencing them
O: When was Nisbett & Wilson’s study and what did it do?
1977- challenged introspective reports
O: What are 2 strengths of the origins of psychology & Wundt’s work?
1) Can establish cause & effect due to control over variables in lab studies
2) Still useful today e.g. Csekszentmihalyi & Hunter (2003)- able to understand momentary situations that make people happy
O: What are 3 limitations of the origins of psychology & Wundt’s work?
1) Unreliable & inconsistent
2) Artificial lab experiments- lacks ecological validity and can’t be generalised
3) Nisbett & Wilson (1977)- challenged introspective reports
B: What is the behaviourist approach?
The belief that all behaviour is learned via classical or operant conditioning
B: What is the behaviourist approach referred to as?
Learning theory
B: What is most research on learning theory carried out as?
Lab experiments
B: What did Pavlov discover and when?
The process of classical conditioning-1927
B: What is the natural stimulus?
The unconditioned stimulus (UCS)
B: What was the UCS in Pavlov’s experiment?
Food
B: What is the natural response to the UCS?
Unconditioned response (UCR)
B: What was the UCR in Pavlov’s experiment?
Salivation
B: What is the acquisition phase?
Where the neutral stimulus (NS) is presented shortly before the UCS and they are paired after a while
B: What is the neutral stimulus (NS) and what was it is Pavlov’s experiment?
A stimulus that doesn’t elicit the UCR- A bell
B: What does the NS become and when?
The conditioned stimulus (CS)- when the NS produces the same response in absence of the UCS
B: What response does the CS cause, and what were they in Pavlov’s experiment?
Conditioned response (CR)- CS= bell, CR= salivation
B: What are 4 important features of classical conditioning?
1) Timing
2) Extinction
3) Spontaneous recovery
4) Stimulus generalisation
B: Why is timing an important factor of classical conditioning?
If the NS cannot be used to predict the UCS (time interval too large) then conditioning doesn’t occur
B: Why is extinction an important factor of classical conditioning?
The CR doesn’t become permanently established as a response- so after a while of the CS being in absence of the UCS it loses its ability to present the CR
B: Why is spontaneous recovery an important factor of classical conditioning?
Following extinction, if the CS & UCS are paired again the link is made more quickly
B: Why is stimulus generalisation an important factor of classical conditioning?
Once an animal has been conditioned, they will also respond to other stimuli that are similar to the CS
B: What are 3 key aspects of the behaviorist approach?
1) Rejected introspection as vague
2) Focus is on observable behaviour only
3) Assumes learning follows the same principles in all species
B: What is classical conditioning?
Learning through association- involving an innate reflex response
B: What is operant conditioning?
Learning through reinforcement - shaping behaviour through consequences
B: What is positive reinforcement?
Adding a pleasant consequence to a behaviour- increasing the likelihood of it occurring
B: What is negative reinforcement?
Taking away something unpleasant- increasing the likelihood of it occurring
B: What is punishment?
An unpleasant consequence to a behaviour- decreasing the likelihood of it occurring
