Photographs of children with Down syndrome elicit less positive attitudes than photographs of typically developing children do, reports new research published in the open access journal PLoS ONE. This effect was strongest for photographs of children with features that are \"strongly typical\" of Down syndrome, and somewhat weaker for images that were more \"weakly typical.\" Although photographs of children with Down syndrome are typically viewed as more positive (\"friendly\" and \"affectionate\") than negative (\"stupid\"), the results of this study reveal underlying stereotypes and negative attitudes about people with Down syndrome at an implicit level, the authors write. This negative bias is observed even among professional caregivers working with intellectually disabled persons.
