How and why particular research methods are used in the CLA (8/22)
introduction
research methods = various ways in which researcher can carry out study + manipulate the data
6 main research methods
CLA = based on mental processes which are carried out by the brain + guide behaviour
experiments
case studies
interviews
observational studies
surveys
correlational studies
triangulation = use of 2 or more research methods to increase credibility of study
aware of researcher / pp bias from methods used
2 main methods at CLA - experiments + case studies
experiments
field experiments
natural (quasi) experiments
lab experiments
researcher manipulates IV + measures DV
attempt to provide controlled conditions by controlling as many extraneous variables as possible
used to determine cause-effect relationship
Loftus + Palmer (1974)
lab experimenting manipulating the IV to measure DV
IV = leading verb
DV = estimated speed of car during crash (mph)
allowed development + recognition of cause-effect relationship
cause = leading verb
effect = influence of specific schema that altered their memory of the event
other research methods wouldn't have been able to highlight this relationship + demonstrate the unreliable nature of our memory
quantitative method
conclusion
case studies
- in-depth study of individual / small group
2 main at CLA = experiments + case studies
type of method used is dependent on the aim of study
experiments
- determine cause-effect relationship between 2 variables
research methods = methods for collecting + analysing data
easily replicated + focused on data concerning the aim of study
investigates unusual phenomena + can't be replicated, lots of data + time consuming
case studies
allows research into unusual psychological phenomena
can't be replicated, time consuming + large amounts of irrelevant data
obtains rich data
lacks population validity (can't be generalised beyond the group studied)
involve a combination of research methods
Milner + Scoville (1957)
qualitative method (but can collect quantitative data)
in-depth study of HM's amnesia condition (inability to make new memories)
in-depth study of an individual / small group
case study used to investigate how operation removing part of HM's hippocampus (part of temporal lobe) can prevent formation of new memories
couldn't be ethically studied in a lab
case study allowed researchers to observe HM's behaviour from when he was a child, adolescent, before and after the operation
