Quizplus · Accepted Answer

The confound in this study is the gender of the experimenter because Consuela and Rick have different genders, so any differences observed between the morning and evening conditions could potentially be due to the gender of the experimenter and not the time of day. The other variables listed (cognitive ability, time of day, random assignment of participants) are not confounds in this study.
