what goes in an informed consent form?
-the topic investigated
-pps job in study
-anything that might change pps willingness to do study
-name and results confidential
-can withdraw
-space for pp to sign
-opportunity to ask Q’s
what goes in a debriefing form?
-thank pp
-tell specific hypothesis you were researching
-inform expected results due to past research
-remind they can withdraw
-lower pp anxiety and offer them support if necessary
-opportunity to ask Q’s
peer review process
-open (researcher and reviewer know who each other are)
-single blind (reviewer knows researcher, researcher doesn’t know reviewer)
-double blind (neither know)
content analysis
-statistical process
-categorising and quantifying events and behaviour as they occur
-qualitative to quantitative data
coding unit
-specific action/behaviour/word/phrases that you are going to count in order to be analysed
evaluation of content analysis
+ allows us to study large amounts of qualitative data
+reliability, often uses inter-rater reliability
-bias, if researcher makes coding unit
-may not be accurate, if material is very ambiguous or unclear
ways to assess reliability
-test-retest, same test is repeated a number of times with the same person
-inter-observer reliability, more than one researcher observes the same pps, looking for a degree of similarity between scores
internal validity
-what goes on inside the experiment (manipulation of IV being effected by confounding variables)
-face validity= whether the aim of the study measures what it is meant to
-concurrent validity= new measures in a study have been compared to a previous valid study
external validity
-extent to which we can generalise
-ecological validity= extent we can generalise to different contexts
-temporal validity= extent we can generalise to different time periods
empirical method
using research evidence to help create and support theories
paradigm
-general theory or law accepted by majority of scientists in that field
-not fixed, change when we gather new evidence which questions the adequacy of the existing paradigm= paradigm shift
science develops through 3 stages:
-Kuhn
1. pre science= variety of theories, but no paradigm
2. normal science= accepted paradigm has dominated science, but over period of time evidence contradicts
3. revolutionary science= paradigm shift, new paradigm is accepted due to new theories and more evidence to reject the old one. Shift is gradual and not all scientists will follow
features in a psychological report
-Abstract (summary)
-Introduction (other studies + the limitations)
-Method
-Results
-Discussions (explanations of behaviour shown)
-References
included in the method of a psychological report:
-design (methodology, variables)
-Participants
-materials
-procedure
-ethics
primary data vs secondary data vs meta analysis
-PD= collected specifically for the research being carried out
-SD= using data that someone else has researched, analysed and published
-MA= using data from primary research on a large scale and re-analysing
thematic analysis steps
ways to display quantitative data
-bar charts= vertical bars equal width apart
-histograms= bar chart but with data on the x and y axis
-scattergrams= used for plotting correlations
-tables
inferential statistics
-researchers can draw conclusions because statistical tests can tell them how likely they are to be correct
probability
-written using < >
-o represents no chance, 1 represents complete chance
-p<0.1 (10%) p<0.05(5%) p<0.01(1%)
test of difference
unrelated, related, association/correlation
nominal= Chill Still Coolly
ordinal= Man Walk Super
interval= U Really Promise
-Chi square, Sign, Chi square
-Mann-Whitney, Wilcoxon, Spearman’s rho
-Unrelated T-test, Related T-test, Pearson’s r
type 1 error vs type 2
-type 1= when the null hypothesis is rejected and the experimental hypothesis accepted
-type 2= when null hypothesis is accepted and experimental hypothesis is rejected
