Autistic disorder is associated with deficits in social function. The disorder may be related to dysfunction in the brain regions that are involved in the process of recognising facial expressions of other persons. Using fMRI, we investigated whether autistic patients with relatively high IQ would have different brain activation on the tasks of recognition(More)
Two studies investigated the role of locomotor experience on visual proprioception in 8-month-old infants. Visual proprioception refers to the sense of self-motion induced in a static person by patterns of optic flow. A moving room apparatus permitted displacement of an entire enclosure (except for the floor) or the side walls and ceiling. In Study 1,(More)
Human infants with little or no crawling experience surprisingly show no wariness of heights, but such wariness becomes exceptionally strong over the life span. Neither depth perception nor falling experiences explain this extraordinary developmental shift; however, something about locomotor experience does. The crucial component of locomotor experience in(More)
Human infants show a peak in postural compensation to optic flow at approximately nine months of age. The current experiment tested whether the magnitude of visual-postural coupling in 9-month-olds increases when terrestrial optic flow is added to a moving room. A secondary objective was to explore whether locomotor experience plays any role in enhancing(More)
Our goal in this study was to examine whether controlled pretense signal presentation by an adult promoted pretend play behavior in toddlers. Seventy-two Japanese toddlers (24 toddlers in the 18-month-old group, 24 toddlers in the 24-month-old group, and 24 toddlers in the 30-month-old group) participated in one of two experimental conditions: signal and(More)
The psychological revolution that follows the onset of independent locomotion in the latter half of the infant's first year provides one of the best illustrations of the intimate connection between action and psychological processes. In this paper, we document some of the dramatic changes in perception-action coupling, spatial cognition, memory, and social(More)
