Abstract
A screening test was developed in order to discover infants showing auditory perceptual abnormalities before the age of one year. The screen was a questionnaire designed to detect in infancy the abnormal auditory behaviours demonstrated by older children with receptive language delay based on auditory perceptual problems. The screen was administered by Health Visitors to 1070 infants at approximately nine months of age. One hundred and nineteen infants were discovered who demonstrated the behaviours understudy and at follow-up evaluation showed receptive language delay. A strong relationship was found between the number of behaviours detected and the degree of receptive language delay. The number of behaviours detected, however, could not alone be used to predict degree of language delay.
