AIM Post-traumatic emotional distress follows exposure to trauma and may be affected by atypical cerebral lateralisation. We aimed to explore the relationship between handedness and emotional dysfunction in people exposed to a nat-ural disaster. METHODS About 22 months after an earthquake, 326 exposed adults completed the Edinburgh Handedness Inventory, the Impact of Events Scale-Revised, and...

Competing theories have posited roles for foetal androgen exposure in the development of human handedness. However, due to practical and ethical considerations, few studies used hormonal measures examine this possibility. The current paper reviews literature reveals a generally inconsistent pattern results. We also present data from longitudinal study prenatal sex hormone subsequent More specif...

It was hypothesized that adult handedness might be predicted from the neonatal grasp reflex. Grasp reflex was measured from right and left hand (10 trials for each hand) in neonates. According to significance for the difference between the mean grasp reflex strength from the right and left hands, the subjects were designated as right-, left-, and mixed-handers. Adult hand preference was assesse...

Research results with regard to handedness and dyslexia have been ambiguous. The present study investigated the relationship between handedness and dyslexia in secondary school students based on genetic (Right-Shift) and hormonaldevelopmental theories of handedness. A total of 135 students (45 dyslexics and 70 ageand sex-matched controls) participated in the study. Handedness was defined accord...

Dermatoglyphics connotesfriction ridges on the skin, visibleon fingers, toes, and palms of individuals. These epidermal ridges, especially finger prints have proven to be viable physical features in criminology, medical diagnosis genetic studies. Handedness; observed as an individual’s preferred use a particular hand over other, for daily activities has been attributed uneven distribution fine ...

Handedness is marked by the preference of one hand over another for fine motor tasks, especially writing. Usually, only one hand is considered dominant; however, there are individuals who exhibit the ability to use both hands equally (mixed-handers). The aim of this study was to identify the incidence for handedness in a sample of Greek adolescents and examine possible gender differences in han...

Although the left and right human cerebral hemispheres differ both functionally and anatomically, the mechanisms that underlie the establishment of these hemispheric specializations, as well as their physiological and behavioral implications, remain largely unknown. Since cerebral asymmetry is strongly correlated with handedness, and handedness is assumed to be influenced by a number of genetic...

various researches know lateral preference of eye and hand pattern as one of the important factors of performing sports skills. this study aimed at investigating the effect of lateral preference of eye and hand pattern on learning basketball free throw skill. from 3000 female students of shahid chamran university of ahvaz, 60 subjects (age range 19-22 yr) were selected purposively as the sample...
