Question

Quizplus · Accepted Answer

Sensitization effects refer to changes in participants' responses due to repeated exposure to the same stimuli or tasks. Within-subjects designs involve using the same participants in multiple conditions or treatments, which increases the risk of sensitization effects. This can lead to demand characteristics, where participants modify their behavior or responses based on their expectations of what the study is measuring. These demand characteristics can threaten the internal validity of the study, as they may confound the effects of the independent variable being manipulated.
