Question

A team of researchers is conducting a study to see if the brain responds the same way to faces of different races as it does to objects of similar and different cultures. They show each participant several pictures of faces (Caucasian and Asian) and several pictures of houses (typically American architecture versus typically Chinese architecture) and measure brain activity via electroencephalography (EEG). Which design best describes the example study?

Answer 1

Within-group factorial design

Explanation:

Within-group factorial design: This is the design in all the participant gets an opportunity to get all the treatment or have to exposed to the condition. The different levels of the independent variables indicated the treatment condition. These variables are manipulated by the experimenter and these variables are treated with a dependent variable that is critical and responsible for the treatment. It is beneficial for two or more groups that are tested under different factors. In this design error variance reduced. In this type of experiment, the individual is assigned for independent variables or treatments.
