We investigated the existence and nature of adaptation aftereffects on the visual perception of basic emotions displayed through walking gait. Stimuli were previously validated gender-ambiguous point-light walker models displaying various basic emotions (happy, sad, anger and fear). Results indicated that both facilitative and inhibitive aftereffects influenced the perception of all displayed emotions. Facilitative aftereffects were found between theoretically opposite emotions (i.e. happy/sad and anger/fear). Evidence suggested that low-level and high-level visual processes contributed to both stimulus aftereffect and conceptual aftereffect mechanisms. Significant aftereffects were more frequently evident for the time required to identify the displayed emotion than for emotion identification rates. The perception of basic emotions from walking gait is influenced by a number of different perceptual mechanisms which shift the categorical boundaries of each emotion as a result of perceptual experience.
