Laterality, Hand preference, Functional cerebral lateralization, Right or left-hand preference


Objective: It was planned to determine the hand preference, the distribution of hand preference by sex, and the dominant cerebral hemisphere regarding hand preference among the students receiving education in the field of health in the faculties of Gazi University (Faculties of Medicine, Dentistry, Pharmacy, and Health Sciences).

Methods: A total of 765 volunteer university students, consisting of 419 female (54.77%) and 346 male (45.23%) students aged between 16-25 years, participated in the study. The study was conducted according to the Coren Stanley questionnaire and score. Statistical analysis was performed by applying the Chi-square test in SPSS 15 statistical program.

Results: The distribution of hand preference was evaluated in seven groups for each hand: strong, moderate, weak, and ambidextrous. The comparison between the sexes in terms of right- and left-hand use preference determined no statistically significant difference (p>0.05). However, it was revealed that the right hand was strongly preferred by a higher number of students of both sexes.

Conclusion: It was concluded that the left cerebral hemisphere could be generally preference is undoubtedly very important to express an opinion about the dominant hemisphere. However, we believe it is necessary to conduct new studies to evaluate the cerebral hemispheres according to their functions.
