Abstract

Multiple Resource Questionnaire (MRQ) and Perceived Work Performance Scale (PWPS) were used to collect responses from the participants. Data were analyzed using Pearson correlation, independent t-test and Univariate Analysis of Variance. Testing four hypotheses, results showed that there is no significant relationship between mental workload and job performance. Also, findings indicated that male workers do not exhibit greater mental workload than female workers. Furthermore, there is no significant main influence of age and educational qualifications on job performance, but there is significant main influence of length of service on job performance. No significant interaction influence of age, educational qualifications and length of service was found on job performance. However, there is significant difference in the level of mental workload of academic and non-academic workers.
