Human infants preferentially look at motions that make sense biologically as opposed to non-biological movements within the first days of life, an ability which is seen as a precursor for attributing intentions to others. Here it is shown that two-year-olds with autism fail to look towards point-light displays of biological motion but are attracted by other properties ignored by control children, a behavioural difference which may reflect changes in the functioning of autistic brains.
