Empiricism - Definition
Knowledge gained through investigation, findings made sense of in terms of theory construction and establishment of general laws that enable accurate predictions
1 of 12
Objectivity - Definition
Scientists detached and not influenced by personal prejudices and expectations, can be improved by standardised procedures, double blind controls and inter-observer reliability
2 of 12
Repllicability - Definition
Suggests study is valid, if repeated the results given are the same, suggests original results are true espeically if found by a different researcher
3 of 12
Control - Definition
Control of extraneous variables necessary in order to establish cause and effect relationships
4 of 12
Theory of Construction - Definition
Way of making sense of research findings
5 of 12
Falsifiability - Definition
It should be possible to disprove a theory
6 of 12
Empiricism - Issue
Psychologists carry out research and collect evidence :) They construct theories :) Don't really have general laws to predict behaviour :(
7 of 12
Objectivity - Issue
Theories often constructed from personal ideas :( Experimenter bias can be a problem :( Procedures in place to prevent experimenter bias :) subjectivity involved :(
8 of 12
Repllicability - Issue
Lab studies are well controlled and standardised instructions allow us to replicate :) studies based on naturalistic observation do not have repllicabillity :( inter-observer reliability allows us to test the accuracy of the findings :)
9 of 12
Control - Issue
Have control in lab studies :) Naturalistic observations, natural experiments and case studies have low control :(
10 of 12
Theory of Construction - Issue
Theories are constructed in psychology based on research and evidence :)
11 of 12
Falsifiability - Issue
Lots of research is falsifiable e.g. biological and behavioural :) psychodynamic is not falsifiable :(
