Psychology SAC 2 Flashcards
Dependent Variable (DV)
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.
Controlled Variable
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.
Independent variable (IV)
Referred to as the ‘treatment’ variable to which participants may be exposed (or not exposed).
What do systematic errors affect?
Systematic errors will reduce accuracy.
Accuracy
How close it is to the true value of the quantity being measured.
Cofounding variables
A variable other than the IV that has an effect on the DV, but cannot be separated from the IV.
Placebo
A false treatment used so that none of the participants know whether they are being exposed to the experimental condition.
Placebo effect
Occurs when there is a change in a participants behaviour due to their expectations about the treatment.
Single-blind procedure
When the participants do not know whether they have been assigned to the control or experimental group(s)
Double-blind procedure
When the participants or the experimenter know which participants have been allocated to the control and the experimental group(s)
Ethics
Refers to the moral principles and codes of behaviour that apply to all psychologists, regardless of the field in which they work.
What are the different parts of ethics?
-Beneficence
-Non-maleficence
-Respect
-Justice
-Integrity
Beneficence
Where research is considered through the scope of maximising the benefits to society while minimising harm to others.
Non-maleficence
In the medical profession, the principle of non-maleficence involves avoiding causing any kind of harm at all.
Respect
The research is shown through the consideration of an individuals welfare.
