Purpose: A recent approach to identifying early markers of risk for autism spectrum disorder (ASD) has been to study infants who have an older sibling with ASD. These infants are at heightened risk (HR) for ASD and for other developmental difficulties, and even those who do not receive an eventual ASD diagnosis manifest a high degree of…

A major concern in recent research is whether perceptual or functional information is of primary importance in children's early word meanings. In the study described here, artificial objects were used so that form and function could be independently manipulated. There were 57 subjects, ranging in age from 2.5 years to adulthood. The subjects were…

Developmental changes in the expression of superordinates in children's word definitions were studied with 96 elementary school students. Superordination increased significantly and changed qualitatively with age, although across grades children produced more superordinates for nouns than for adjectives or verbs. (SLD)

Research was conducted to compare evidence of implicit processing in children and adults. Implicit processing was defined as inductive cognitive activities which enable people to abstract complex knowledge from the environment. The knowledge acquired is tacit; it guides subjects' behavior in various situations without the subjects necessarily…

There are problems in interpreting the naming behavior of children. Children may misname a word because the word is absent from their vocabulary, because it is not yet firmly established, or because of a word retrieval or lexical assessing problem. Preliminary results are reported of an experimental technique designed to account for these…

A study compared learning disabled (LD) adolescents with oral expressive problems to non-learning-disabled (NLD) adolescents on a formal operations task, with emphasis on a comparison between non-verbal performance and verbal explanations of the task. This paper reports part of the study, a comparison of two high school freshman subjects. The task…

This paper examines the referential strategies used by Japanese children and adults in two story telling tasks focusing upon the following discourse contexts: (1) first mentions of story characters, (2) references in subject position to the same character, and (3) references to another character. The subjects, 60 children and 10 adults, were…

If older children automatically label pictorial stimuli, then their performance should be impaired on tasks in which such labeling would increase the error rate. Children were asked to learn pairs of verbal or pictorial stimuli which, when combined, formed a different compound word (BUTTER-FLY). Subsequently, a false recognition test that included…

Piaget has suggested that a child's language reflects the degree to which he is able to take into account the point of view of his listener. His inability to do so results in what Piaget calls egocentric speech whereas what Piaget calls socialized speech indicates that the child actually adopts his listener's viewpoint and engages in an exchange…

The existence of a developmental sequence for the acquisition of specific complex syntactic structures in English was investigated through an analysis of eight studies of Danish subjects. The studies involved Danish speaking subjects acquiring English as a second language at ages 7-10, 13, and 18. The evidence from these studies demonstrate a…

This study tested the hypothesis that maternal drinking early in pregnancy affects the development of the child's central auditory processing. A follow-up study of 167 children took place 6 years after their mothers participated in a survey concerning health and drinking practices during the early stages of pregnancy. Indications of problem…

Early socialization within the family and its differential effects on the development of verbal intelligence skills were the subjects of this longitudinal study. Fifteen families with one child between one and three years old and a second child born at the beginning of the investigation took part in a longitudinal study covering a seven-year…

Children may be able to gain partial information about the meaning of a word from clues, such as how it is used in a sentence and what words it is contrasted with. This strategy, known as "fast mapping," may provide a very useful first step in language learning. One question which arises from studies of fast mapping is whether fast…

Extensive longitudinal data were gathered on a child's entry into the symbolically mediated modal world by examining changes in the semantics and pragmatics of her uses of modal auxiliary verbs. The data are 53 transcripts of natural conversations between a girl, Nina, and her mother recorded periodically from her 23rd month to her 39th month. The…

The results obtained by researchers interested in the speech-time relationship indicate that the sequential organization through time of speech sounds necessary for communication requires a universal "grammar" consisting of vowel and consonant sequences and an awareness of the duration experienced in that process, as well as the memory…
