Introduction 
Males and females search and treat information in electronic environments differently as evident from differences 
in scan paths (i.e. Roy & Chi, 2003). These differences might not only be cognitive, but also biomechanical in their 
origin (Kimura, 1999; Wilner & Nakayama, 2006). In this study we try to distinguish between the biomechanical 
and the cognitive aspects of these sex differences. We asked subjects to track and/or click on a stimulus on the 
screen with the mouse while manipulating perceptual load in different ways.  
Tasks 
• tracking of a translating or rotating ball 
• clicking on disks presented at a random position 
Manipulations 
• BALLS velocity, distractors 
• DISKS size, contrast, distractors
