The topic of vigilance behavior in today's work setting such as air traffics control (ATC), industrial quality control, sonar and radar operations etc. is gaining much importance among cognitive neuroscientists, academicians, researches as well as psychologists. Like other cognitive capacities, the capacity to sustain attention i.e. vigilance, has been considered to represent a limited resource. This is regarded as the most important determinant of the vigilance decrement. The majority of investigators report large individual differences in susceptibility to decrement. Thus, personality has been found to affect vigilance performance across time periods, besides other individual difference factors. Extraversion and introversion is the central dimension of human personality which differs from each other in terms of cortical arousal level. Researches demonstrated that introverts, who had high level of arousal, showed less decrement function than extraverts, having low activation. But in several experimental studies hypothesized of greater decrement for extraverts was not supported. Moreover, the pattern of vigilance decrement changed with the time of day. Thus, as the technical development is growing rapidly, it has become increasingly necessary to examine how vigil function changes with personality type and task demand and to understand the extent to which these changes can affect their functioning. The researches on the personality aspect, until recently, have been limited in scope while it plays important role in predicting decline reactions during vigil. The present study examined the relationship of personality and sustained task performance. The experiment was conducted on 30 students of Banaras Hindu University (M±SD=22.35year±2.55). Participants were classified as introverts (N = 15) and extraverts (N = 15) based on their EPQ-R score. Performances in terms of correct and incorrect detection were collected.

Abstract


The topic of vigilance behavior in today's work setting such as air traffics control (ATC), industrial quality control, sonar and radar operations etc. is gaining much importance among cognitive neuroscientists, academicians, researches as well as psychologists. Like other cognitive capacities, the capacity to sustain attention i.e. vigilance, has been considered to represent a limited resource. This is regarded as the most important determinant of the vigilance decrement. The majority of investigators report large individual differences in susceptibility to decrement. Thus, personality has been found to affect vigilance performance across time periods, besides other individual difference factors. Extraversion and introversion is the central dimension of human personality which differs from each other in terms of cortical arousal level. Researches demonstrated that introverts, who had high level of arousal, showed less decrement function than extraverts, having low activation. But in several experimental studies hypothesized of greater decrement for extraverts was not supported. Moreover, the pattern of vigilance decrement changed with the time of day. Thus, as the technical development is growing rapidly, it has become increasingly necessary to examine how vigil function changes with personality type and task demand and to understand the extent to which these changes can affect their functioning. The researches on the personality aspect, until recently, have been limited in scope while it plays important role in predicting decline reactions during vigil. The present study examined the relationship of personality and sustained task performance. The experiment was conducted on 30 students of Banaras Hindu University (M±SD=22.35year±2.55). Participants were classified as introverts (N = 15) and extraverts (N = 15) based on their EPQ-R score. Performances in terms of correct and incorrect detection were collected.
