What’s content analysis?

Turning qualitative data into quantitative data.

Directional hypothesis definition.

When the hypothesis states that something will cause something - as a result of previous research’s conclusions.

What are the different experimental designs?

Independent groups - two different groups of two different things. These are compared (worst one).

Repeated measures - same group does two conditions

Matched pairs - independent groups, but people are matched on key characteristics and compared (best one).

What are behavioural categories in psychology?

Behavioural categories in psychology are specific, operationally defined groups of behaviours that researchers use to categorise observations and conduct analyses.

They help ensure that data collection is systematic and quantifiable.

What is time sampling?

Marking a behavioural category after different amounts of time periods.

How you pick your participants

Investigator effects definition

When the experimenter biases the experiment towards the results they want to achieve.

What is a test-re-test?

Testing something again to improve reliability.

What are the three different types of validity?

Face validity - getting someone to see if your experiment seems reliable

Concurrent validity - when past research is similar to your results

Ecological validity - how applicable your results are to real-life

Objectivity definition.

When something is a fact.

Falsifiability definition

The principle that a scientific theory or hypothesis must be structured in a way that it can be tested and potentially proven false by evidence.

(Eg Freud’s ideas about the unconscious are often criticised for lacking falsifiability, since they cannot be tested in a way that could prove them wrong)

Paradigm definition

General theories/ideas believed within a society

Experimental design: what are the features of a psychological report?

1. Abstract - brief study of experiment - including the aim, methods, results and conclusion (200 words)

2. Intro - Outlines background and relevant studies, states hypothesis

3. Method -
