Late talkers show no shape bias in a novel name extension task

By 2½ years of age, children typically show a shape bias in object naming – that is, they extend object names mostly to new instances with the same shape. The acquisition of a shape bias is related to a marked increase in the rate of object name learning. This study asks whether, conversely, children who do not readily acquire new object names lack a shape bias. Twelve 2- to 3-year-old ‘late talkers’– children whose total vocabularies rank below the 30th percentile for their age – were compared with age-matched children with larger vocabularies in a novel object name extension task. The controls extended novel names across novel objects with the same shape. The late talkers showed no group perceptual bias, but many individuals extended novel names across objects with the same surface texture. The implications of the results both for the role of attentional biases in object name learning and for the etiology of some late talking are discussed.      

Development of executive attention in preschool children

The development of self-regulatory systems during the preschool years is accompanied by a dramatic increase in the ability to inhibit actions based on the directions of others. Several tasks have shown evidence of changes in self-regulation during the fourth year of life. The current cross-sectional study used a Simple Simon task, in which 33 3- to 4-year-old children were asked to respond to the command of one large toy animal but not to the command of another. Three important aspects of self-regulation were examined: the ability to inhibit action in the face of conflict, error detection/correction and the use of verbal and physical control strategies. The ability to inhibit a response in this task increased from 22% to 90% between 36 and 48 months of age. Post error slowing of Reaction Time (RT) indicative of error detection emerged at about the same age as successful inhibition. Physical rather than verbal self-regulation strategies were spontaneously employed by children to aid in the process of inhibition.
