title: Non-Expert Ratings of Infant and Parent Emotion: Concordance with Expert Coding and Relevance to Early Autism Risk.
abstract: This study investigated a novel approach to obtaining data on parent and infant emotion during the Face-to-Face/Still-Face paradigm, and examined these data in light of previous findings regarding early autism risk. One-hundred and eighty eight non-expert students rated 38 parents and infant siblings of children who did (20) or did not (18) have autism spectrum disorders. Ratings averaged across 10 non-experts exhibited high concordance with expert facial-action codes for infant emotion, and 20 non-experts were required for reliable parent ratings. Findings replicated the well-established still-face effect and identified subtle risk associations consonant with results from previous investigations. The unique information offered by intuitive non-expert ratings is discussed as an alternative to complex and costly behavioral coding systems.
