EFFECTS OF WORKING MEMORY DEMAND ON PERFORMANCE AND MENTAL STRESS Essay

EFFECTS OF WORKING MEMORY DEMAND ON PERFORMANCE AND MENTAL STRESS DURING THE STROOP TASK - Essay Example Mental stress results from the lack of balance between external requirements, and the ability of the individual to accomplish them. Mentally or emotionally related stress influences the daily life of a human being, and his or her performance. If one becomes exposed to extreme mental stress, it affects the nervous system, and can affect their performance severely. Most of the stressors associated with human computer interaction occur as a result of massive workloads, a lot of work pressure, job control tasks that are not efficient, and which are also monotonous, poor relationships between supervisors and the supervised. It is suggestive of the demand/control model of work strain, that little control and low social supports happen to be demanding. Working in shifts, factors that are human related and ergonomics have an association with mental stress. A dependable amount of evidence shows that heart diseases have links with extreme work demand. Therefore, evaluating the rate of heart ac tivity can help in gauging occupational risks. This studys purpose is to measure mental stress and monitor the heart rate variability during the low and high working memory (WM), needs affected by Stroop interference. The other aim is to measure the performance and time taken to respond during the Stroop task and to study their drift during high and low working memory demands. The third aim is to foresee the affiliation between mental stress and functioning. In carrying out the study, the rate of the heart should be recorded during both rest period, and also during the performance of a Stroop task. Both the high and low working memories are acquired by raising the amount of Stroop interference. The time taken to respond and the performance are computed for every hard stage of the Stroop task. This should be computed during the high and low working memory demand. Stress that is as a result of Human Computer Interaction (HCI) has links to the increased danger of
