Mental Rotation

This spreadsheet contains behavioural data collected from two partially overlapping samples of university students as they completed two computerized tests involving the mental rotation of hands: a same-different task (N = 104) and a laterality judgment task (N = 129). Stimuli included views of the palm and the back of the left and right hands, shown upright or rotated (medially or laterally) by either 60 or 120 degrees. In addition to performing the tasks, participants supplied basic demographic information (age, sex, handedness) and completed self-report measures tapping into alexithymia [Toronto Alexithymia Scale (TAS-20)], sensory processing sensitivity [the Highly Sensitive Person Scale (HSPS)], depression [Patient Health Questionnaire-9 (PHQ-9)], and anxiety [General Anxiety Disorder-7 (GAD-7)].
