اثرات روان رنجورخویی و سابقه حجم کاری بر عملکرد

This study manipulated workload levels to test Eysenck's theory of neuroticism by examining individuals' differential responses to the stress of sudden shifts in workload. A sample of 194 participants who had completed an inventory to assess neuroticism were randomly assigned to either a High-to-Low or Low-to-High testing condition. Participants performed an auditory vigilance task while reaction time and correct responses were assessed. Multiple regression analyses were conducted and results indicated that higher levels of neuroticism were associated with decreased reaction time in both conditions. In addition, individuals higher in neuroticism evidenced fewer correct responses in the Low-to-High workload condition. Results of this study are generally consistent with Eysenck's theory of neuroticism.
