Background: The relationship between handedness, intelligence and cognitive abilities has been of interest of many researchers for a long time. Objective: The aim of this study is to compare intelligence (verbal and practical) and its subscales scores based on handedness between two groups, left and right-handed. Method: The sample comprised 120 graduate students who were randomly selected and measured by Edinburg's Handedness Inventory and Wechsler’s Adult Intelligence Scale. Results: test and Multivariate analysis of variance showed that there is significant difference between the left-handed and right-handed in overall intelligence score (t=2.63, P<0.05), verbal intelligence (F=61.13, P<0.01), three of verbal intelligence subscales (Information, Digit span and comprehension) and some of practical intelligence subscales (picture completion, picture arrangement, block design). The total and verbal intelligence of the left-handed is more than the right-handed. But, the practical intelligence (F=0.021, P>0.05) and its two subscales (Object Assembly and coding) did not differ significantly between the two groups. Conclusion:This research could create appropriate learning environments and sensitivity to the complexity and the combination of cognitive, psychological and neurological excelled in terms of learning and intelligence help.

This study investigates the effects of computer's games in improving mental rotation ability. The subjects comprised 87 I/• years-old students (41 male and 45 female) who were randomly selected and assignmened in 3 groups (Puzzle games, action games and control group. The experiments were done using an experimental 3 xJ factorial design by pretest-post/es/ control group, and within 8 sections. Mental Rotation was measured by an online rest developed by Chay (2000) based on the Vandenberg and Kuse (I 978). According to the results, males on average performed helter than females in mental rotation ability o.f accuracy, bu/ no difference in speed. The results indicated that gender differences. /11 playing computer's games were decreased. Tetris groups (both male and female ) had higher improvement than another groups and also Navy Seals group (alone male) had improvement than control groups. This appears to be no improvement in reaction limes for mental rotation. Results are discussed by different theories and also within a nature-nurture interaction framework o.f gender differences in spatial abilities
