Sex Variation of Motion Stereotypic Response among Adult Bengalee Population for the Operation of Some Simple Control-Display Units

Abstract

Population stereotype point out to a long-term habit and well embedded knowledge of a particular population. This study was carried out to evaluate the variation in index of reversibility, response preference and response initiation time among male and female subjects for some simple analog control-display units. A total of 999 subjects were responded, among them 591 were male and 408 were female (having the age range of 15-60 years). To conduct the study five types of analog displays viz., rotary control knob with horizontal display, rotary control knob with vertical display, and rotary control knob with circular display, horizontally aligned rocker switches and vertically aligned rocker switches for electric lights were fabricated. The subjects were asked to move the control to get the desired display and the response preference and response initiation time were noted as the results. The results showed that the best control-display unit was the rotary control-vertical display combination on the basis of index of reversibility for both sexes. Statistical analysis of the data showed that preferred response percentage or were significantly (P less than 0.05 or less) different for both sexes in case of all the rotary control analog display operations but for rocker switch-electric light unit operation it was found that both group showed similar stereotypic strength and direction. Response initiation time also found to be significantly (P less than 0.001) different, it was also found that higher preferred response percentage showed shorter response initiation time. It may be concluded that gender has a profound impact on motion stereotypic responses.
