Several studies have demonstrated a relation between executive functioning (EF) and theory of mind (ToM) in preschoolers, yet the developmental course of this relation remains unknown. Longitudinal stability and EF-ToM relations were examined in 81 children at 24 and 39 months. At Time 1, EF was unrelated to behavioral measures of ToM but was…

The authors asked whether there is evidence to support the existence of the vocabulary spurt, an increase in the rate of word learning that is thought to occur during the 2nd year of life. Using longitudinal data from 38 children, they modeled the rate of word learning with two functions, one with an inflection point (logistic), which would…

In many cognitive domains, learning is more effective when exemplars are distributed over a number of sessions than when they are all presented within one session. The present study investigated this "distributed learning effect" with respect to English-speaking children's acquisition of a complex grammatical construction. Forty-eight children…

Two tasks of word identification were proposed to children in their last year of upper preschool classes. The results show that identification is not based on an holistic processing but on an analytic one: some letters are enough, especially the first ones. Moreover, their order does not matter. During this period where reading is visuo-semantic…

It is a matter of debate whether the development of theory of mind (ToM) depends on linguistic development or is, rather, an expression of cognitive development. The study of genetic syndromes, which are characterized by intellectual impairment as well as by different linguistic profiles, may provide useful information with respect to this issue.…

Proximal environmental variables illustrate aspects of the environment that are experienced directly and specifically by the child. The current study examined the associations between three proximal environmental variables: (1) quality of the home environment, (2) regularity of family routines and (3) frequency of parenting daily hassles and…

Three experiments examined the relation between language acquisition and other symbolic abilities in 18- and 26-month old infants. Infants' ability to learn either words or symbolic gestures as names for object categories were compared across age groups. Findings indicated that infants at both ages learned novel words as symbols for object…

Deaf children's thought processes are analyzed in regard to J. Piaget's theory of cognitive development. (Author)

One of a series written for parents and other caregivers, this handbook on child development focuses on children from 2 to 6 years of age. Contents describe (1) physical development in terms of body size and shape, brain and eyes, and motor skills; (2) cognitive development and language acquisition; (3) personality development, with particular…

Subjects in grades 2, 6, and college were asked to sort 50 pictures according to several class labels, each with a functional equivalent. (ST)

Three experiments with children between 5 and 7 years are described. It is shown that nominal predication of an unknown word by a superordinate term enables young children to make appropriate inferences concerning its attributes. The results are discussed in relation to semantic development and reasoning in the young child. (Author/RM)

This is the second volume in a series that records the official Symposium Proceedings of the Jean Piaget Society and examines the theoretical, empirical, and applied aspects of Jean Piaget's seminal epistemology. The 12 papers are divided into four areas: language development, formal reasoning, social cognition, and applied research. The topics of…

Twenty-four profoundly deaf children (7 to 13 years old) from a residential school were presented with conservation problems of liquid, matter, weight, and volume. Analyses of variance showed that age was significant beyond the .01 level and type of task (conservation) at the .25 level. No significant sex effect was found. Differences among means…

This paper presents a system for describing and categorizing various theories of language and thinking. Within this system, theories are described in terms of their position on three basic issues: (1) the direction of dependency between language and cognition, (2) the necessity of that dependency, and (3) the level of specificity at which the…

In this study, 50 infants (15 to 18 months of age) were shown four different film sets in an effort to determine (1) whether infants can perceive action role reversals between an actor and recipient of the action when the direction of the action is ruled out as a cue and (2) whether infants consider only animate objects to be potential…
