Abstract
The relationship between mean intelligence quotient (IQ), hand preferences and visual memory (VM) were investigated on (N=612) males and females students trained in different educational programs in viewpoint of laterality. IQ was assessed by cattle’s culture Fair intelligence test-A (CCFIT-A). The laterality of the one side of the body was assessed by a questionnaire with 20 items. For VM, word lists with 15 items derived from the root of the Turkish word “to run” were projected on a screen. Subjects were allowed to see the words for 30 sec., and write down the remembered-words in 40 sec. There was any relationship between the hand preferences and IQ levels in right-and left-hander for first ten items (Q1, p>0.05), and also there was no relationship between the hand preferences and remembered words (RW) in left-hander (p>0.05). There was, however, a negative relationship between the hand preferences and RW in right-handers (p<0.05). For second ten items (Q2), there was no relationship between the hand preferences and IQ of left-handed subjects (P<0.05), but there was a positive relationship between the hand preferences and IQ in right hander (p<0.05). However, there was no relationship between hand preferences and non remembered words (NRW) (p>0.05). It was concluded that there was a relationship between the laterality, NRW and IQ in right hander.
Key words: Intelligence, laterality, education, remembering, students.
