Objective: This study was conducted to investigate the effect of handedness on lateralization of facial emotional processing in children.
Method: The subjects (30 righthanded and 30 left-handed) were selected based on Chapman’s Handedness Inventory and the results of a semi-structured interview. Lateralization of emotional processing was assessed by employing happy, angry and neutral schematic emotional faces in visual field task. Data were analyzed through repeated measures design procedure.
Results: The results showed that left-handed subjects had right visual field biases, therefore, they perceived emotional faces presented in the right visual field much faster than in the left visual field. This bias was significant for angry emotional faces. There was no effect of lateralization in right-handed subjects.
Conclusion: Handedness affects on lateralization of emotional processing, and patterns of emotional processing lateralization are different in left- and right-handed individuals.
