The development of static and dynamic perception for stimuli requiring different levels of neural analysis was assessed by measuring orientation-identification and direction-identification thresholds for both lower-level [or first-order (FO)] and higher-level [or second-order (SO)] stimuli as a function of age. Results demonstrate that both lower-level and higher-level perception continue to develop during school-age years in both dynamic and static domains. When compared with adult levels, dynamic performance for 5-6-year-olds is significantly decreased for SO, but not for the FO perception; however, type of stimulus (FO vs. SO) did not affect the development of static perception. We therefore suggest that levels of stimulus complexity should be considered an important variable when assessing and making inferences regarding the typical and atypical development of static and dynamic perception.
