Q

Random allocation and its use

A

Allocating participants randomly such that each person has an equal chance of being in any condition.
It is used to reduce the effect of confounding variables such as individual differences.

16
Q

Practice effect

A

When participants’ performance improves due to experiencing the tasks more than once

17
Q

Fatigue effect

A

when participants’ performances decline due to physical tiredness, boredom etc with the task because they experience the task multiple times

18
Q

Ways to overcome order effect?

A
  • randomisation
    -counter balancing
19
Q

randomization

A

use of chance procedures in psychology experiments to ensure that each participant has the same opportunity to be assigned to any given group

20
Q

counter balancing

A

the participant sample is divided in half, with one half completing the two conditions in one order and the other half completing the conditions in the reverse order
