We examined if and when English-learning 17-month-olds would accommodate Japanese forms as labels for novel objects. In Experiment 1, infants (n = 22) who were habituated to Japanese word-object pairs looked longer at switched test pairs than familiar test pairs, suggesting that they had mapped Japanese word forms to objects. In Experiments 2 (n =…

Uncertainty was researched as a perceptual structure which mediates the transition from sensorimotor activity to language. The guiding notions are that the attentional system is geared to uncertainty from the beginning of life and that a speaker's language use is coordinated with this system as it emerges. (Author)

In three experiments, a multiple habituation paradigm was used to examine the ability of 7- and 9-month-old prelinguistic infants to form a natural, basic-level object category. Findings constitute independent evidence for the existence of a linguistically relevant nonlinguistic category prior to the onset of word comprehension. (SED)

The relationship of object permanence and classification skills to receptive and expressive language development was investigated in infants. Object permanence, classification, and parent-child verbal interaction ratings were about equally related to language comprehension functioning, while permanence was more strongly related to language…

Pointing and gestures in 47 infants was investigated in 2 experiments contrasting declarative-referential vs. imperative-instrumental conditions of communication, and another study of 7 infants examined prepointing transitional phenomena. Results show gestures are produced differently in experimental conditions: reaching is only produced in…

Discusses the audio and video-recorded longitudinal data from six infants with varying degrees of vision. The findings indicate that there are basic differences in early language, which appear to reflect differences in cognitive development. (SL)

Examination of object word learning and use in beginning (vocabulary of less than 50 words) and advanced (vocabulary of more than 50 words) infant speakers indicated that both groups formed concepts, learned, and generalized words for the to-be-learned objects. Advanced speakers learned more words and concepts and engaged in broader generalization…

Four children were videotaped playing with their mothers, first in a situation with gestures, and then in a situation without gestures. Results showed that maternal gestures have more of a role in maintaining attention and flow of interaction for young children than they do in providing specific cues to the grammar the child is acquiring. (SL)

Discusses children's acquisition of non-nominal, abstract words and argues that the use of these words parallels the child's cognitive development in trial-and-error problem solving and in development of insight. (EKN)

We investigated infant precursors of low language scores in early childhood. The sample included 373 probands in 130 monozygotic (MZ) and 109 same-sex dizygotic (DZ) twin pairs in which at least one member of the pair scored in the lowest 15th percentile of a control sample on a general language factor derived from tester-administered tests at…
