Psychology SAC 2

the aspect of a participants’s behaviour or experience that is assumed and expected to change as a result of the manipulation of the IV selected by the researcher.

Is one that is considered to have an effect on the dependent variable in an experiment so it needs to be held constant (‘controlled’) to remove its potential effects.

Referred to as the ‘treatment’ variable to which participants may be exposed (or not exposed).

Systematic errors will reduce accuracy.

How close it is to the true value of the quantity being measured.

A variable other than the IV that has an effect on the DV, but cannot be separated from the IV.

A false treatment used so that none of the participants know whether they are being exposed to the experimental condition.

Occurs when there is a change in a participants behaviour due to their expectations about the treatment.

When the participants do not know whether they have been assigned to the control or experimental group(s)

When the participants or the experimenter know which participants have been allocated to the control and the experimental group(s)

Refers to the moral principles and codes of behaviour that apply to all psychologists, regardless of the field in which they work.

Is a participant’s right to privacy with regard to access, storage and disposal of information collected about them that is related to research.

In research should not occur unless it is necessary. It is used in some cases where giving participants information about an experiment beforehand might influence their behaviour during the study and thus affect the accuracy of results.

involves participants being informed of the study’s true purpose once the experiment has ended.
