The present study was conducted to investigate relationship between working memory (WM) capacity and the constituents of EPQ-R, especially trait measures relating to neuroticism and extraversion.125 participants volunteered (Mean age= 20.96, SD= ± 1.33), out of which 59 were female and 67 were males, to participate in the present study. EPQ-R questionnaire was used to measure personality and modified Automated operation span task (AOSPAN) was adapted to measure working memory capacity of participants. It is a dual task condition in which participants were required to perform memory task as well as simple mathematical equations. Participants had to recall letters in order of presentation in each set with maintaining minimum 80% accuracy on mathematical portion of the task. Results revealed that extravert participants showed superior working memory capacity than introvert and ambivert participants. Moreover, high neuroticism group perform shoddier on WM task in comparison to low and intermediate neuroticism group.Keywords

Vigilance decrement has been the main focus of researchers over time. Increasing human-machine interactions and potential risks involved have aggravated researchers to investigate the vigilance phenomenon in various perspectives. Cognitive demand has been identified as an underlying cause of vigilance decrement. Task type and event rate are the important contributors to workload and stress in a vigil task. Successive tasks are more demanding than simultaneous tasks and high event rate more demanding than low event rate conditions. It is significantly important to pay cautious consideration on demand factors while designing systems and work environment involving vigilance functions.Keywords

In daily life we usually scan the environment in terms of critical events over non-critical events. The ability to detect and maintain attention for extended periods of time is referred as sustained attention or vigilance. The present study examined the effect of visual warning cue on sustained attention task performance. Twenty undergraduate students of Banaras Hindu University were randomly assigned mto two different experimental conditions. A 2 (warning cue: No warning, warning cue) x 4 (Block: 10 minute each) mixed factorial design with repeated measure on last factor was used. Super Lab software was used to design and conduct successive go/no-go visual sustained attention task. Reaction time, correct detection and incorrect detection were recorded as dependent measures. Findings revealed that participants took less time to respond, when warning cue was preceded the target. However, rate of correct detection and false alarm scores did not differ significantly under both conditions. Real world application of this research includes traffic system, system that requires operators to sustain attention to complex tasks while receiving and responding to warning.Keywords

Human brain aging is a complex process, involving changes in anatomy, physiology and cognition. The process which actively suppresses task-irrelevant response for task-appropriate responses is referred as response inhibition. Older adults have particular deficiencies in the inhibitory attentional control mechanisms that serve to prevent or stop the processing of task-irrelevant stimuli (i.e., distraction). The present study examined differences in the performance of the young and older adults on tasks evaluating response inhibition by using a distracter-response binding flanker task. The sample comprised of 10 young (Age range: 18-35 years) and 10 older adults (Age range: 55-65 years) and the responses of the participants were taken across congruent and incongruent conditions. Results were discussed in terms of accuracy and reaction time measures for young and older adults. ANOVA was performed to investigate whether there was a significant difference in response inhibition between young and older adults.Keywords

The present study was intended to explore the effect of time durations on time perception using prospective judgment of time paradigm. The dual task paradigm was used for the study. The primary task was intended to estimate elapsed time while performing the executive task and secondary task was design to measure executive performance. A reproduction method was used to estimate the time judgment of the participants. Thirty five students from Banaras Hindu University were taken as participants with age ranged from of 20 to 26 years (21.51 years, SD=1.50). Ratio and Absolute error was derived from observed reproduction of time and considered as dependent measure. The findings reveled that Accuracy of time estimation is better under short time duration in comparison to medium and long time duration. Further, it was also found that participants underestimated the period of time-on- task more under longer duration condition in comparison to medium and short time duration of executive task.Keywords
