Gender Influences Performance on Choice Reaction Time Task

According to Madden (2001), “processing speed is a fundamental property of the central nervous system.” However, what if one gender’s brain processing results in an advantage over the other because of better reaction times? Current studies show contradictory findings when reporting gender differences on reaction time tasks (Adam et al., 1999; Calvo, 2009; Lahtela et al., 1985). Reaction time is referred to as “the amount of time from the onset of the stimulus beginning and responding” (Draper et al., 2010). However, the etiologies of gender differences on reaction tests are more difficult to explain; nevertheless, many researchers have explanations for these gender differences.
According to Lahtela et al., (1985) gender differences on reaction task can be attributed to females excelling over counterparts on semantic component reaction tasks; while, males excel over counterparts on spatial features reaction tasks. Another possible alternative explanation for gender differences on reaction tasks is males and females brains differences. fMRI brain scans show that there is a higher bilateral symmetry in female brain and a higher asymmetry in male brains (Kalb et al., 2004). These brain differences can have an impact on incoming stimuli though the dorsal and the ventral stream cortical. The “dorsal stream provides the basis for conscious and unconscious knowledge of ‘where’ something is in visual space, as well as the tracking of object movement” While, the “ventral stream processing provides information for conscious recognition of ‘what’ something is, including its associated characteristics” (McGivern et al., 2012). Through the dorsal and cortical streams operating in union, it allows incoming stimulus to be processed toge...
