The current study aimed to detect the effect of laterality, sex and stimulus onset a synchrony (SOA) on dual task interference among university students. The study was conducted on a group of university students, who were (50) students (22 males and 28 females). The hypotheses were as follows:
1) The laterality, crossing, sex and stimulus onset a synchrony have an effect on the performance of the first task among the university students, in dual task performance.
2) The laterality, crossing, sex and stimulus onset a synchrony have an effect on the performance of the second task among the university students, in dual task performance.
3) The laterality, crossing and stimulus onset a synchrony could contribute, with varying degrees, in predicting the response time average for the first and second response among the university students.
Tools:
E-Prime program was used for designing the study tasks, presenting stimuli and monitoring responses. Also, we used hand-preference questionnaire to ensure the selection of the right-handed students.
Results:
Results of the current study show the verifying of most hypotheses, where there was significant effect for laterality on the performance efficiency for the first and second task. The performance in the crossing condition was substantially less than it in the other lateral conditions. Findings also revealed the superiority of males to females in the dual tasks performance. But Results indicated that the contribution of the study variables was too little, concerning predicting the response time of the first and the second.
