Action Perception in 10 Month Old Infants

Paul Ghoshy

Research on early action perception has documented infants’ astounding abilities in tracking, predicting, and understanding other people’s actions. Common interpretations of previous findings tend to generalize across a good range of action stimuli and contexts. During this study, ten-month-old infants repeatedly watched a video of a sameaged crawling baby that was transiently occluded. The video was presented in alternation with videos displaying visually either dissimilar movements (i.e., distorted human, continuous object, and distorted object movements) or similar movements (i.e., delayed or forwarded versions of the crawling video). Eye-tracking behaviour and rhythmic neural activity, reflecting attention (posterior alpha), memory (frontal theta), and sensorimotor simulation (central alpha), were concurrently assessed. Results indicate that, when the exact same movement was presented during a dissimilar context, it had been tracked at more rear parts of the target and posterior alpha activity was elevated, suggesting higher demands on attention-controlled information science.
