The current study aimed to compare the visual search development between intellectually supernormal (gifted and talented) and normal children. 124 children aged 9-13 years old participated in the visual search experiment, 68 supernormal and 56 normal children respectively. The standard visual search paradigm was used and participants’ reaction time (RT) was recorded through the DMDX system. Search RTs underwent analyses of variance (ANOVAs) with age group and IQ group as between-subjects factors, the features and the set size as within-subject variables. The result showed that supernormal children performed more quickly than that of normal children, the reaction time (RT) also showed expected improvement in speed of information processing with their age increasing among both groups. Moreover, both the supernormal and normal groups displayed similar patterns in searching color features (in parallel processing) and conjunctions (in serial processing).
