brain scanning and neuroscience studies
6 of 35
what do godden and baddley and craik and tulvings study offer?
controlled methods of study offers reductionism and operationalisim varaible

measurable biological information
8 of 35
What concepts are hard to measure in the cognative approach?
cue dependance forgetting
9 of 35
What methodologies are hard to generalise ?
Case studies because its hard to form a scientific body of knowledge

Adams et al looked into homophobia
11 of 35
Case studies were used alot by freud why is this a negative in terms of psychology as a science?

In the learning approach what did the experiments often consist of?
animal studies in the lab study e.g. skinners and pavlov
18 of 35
Why is there reductionism?
because behaviour is reduced to parts to make it more measurable
19 of 35
Whats the approaches aim?
to discover general laws of behaviour and development which is scientific

What theory did Karl Popper propose to determin whether a theory is scientifc?
Hypothetico-deductiv model
22 of 35
What does a hypothesis have to be based on?
Scientific theory

based on means of testing and amending the hypothesis repeating the cycle
25 of 35
What should happen if theory isn't proven?
it must be rejected not amended

Why can this model be applied to psychology?
because this cycle is what psychology is about ( amending , developing and testing theories)
27 of 35
How do you know if it's a psychological hypothesis ?
you are testing by experimentation building knowledge in a scientific way ( cannot be done with case studies)
28 of 35
What is Falsification?
is the process of trying to prove your hypothesis wrong ( if not its correct)
