Advanced theory-of-mind (AToM) development was investigated in three separate studies involving 82, 466, and 402 elementary school children (8-, 9-, and 10-year-olds). Rasch and factor analyses assessed whether common conceptual development underlies higher-order false-belief understanding, social understanding, emotion recognition, and…

Category-based induction is a hallmark of mature cognition; however, little is known about its origins. This study evaluated the hypothesis that category-based induction is related to semantic development. Computational studies suggest that early on there is little differentiation among concepts, but learning and development lead to increased…

In the world, the manners and paths of motion events take place together, but in language, these features are expressed separately. How do infants learn to process motion events in linguistically appropriate ways? Forty-six English-learning 7- to 9-month-olds were habituated to a motion event in which a character performed both a manner and a…

Fundamental to amassing a lexicon of relational terms (i.e., verbs, prepositions) is the ability to abstract and categorize spatial relations such as a figure (e.g., "boy") moving along a path (e.g., "around" the barn). Three studies examine how infants learn to categorize path over changes in "manner," or how an action is performed (e.g., running…

There is ongoing debate about children's ability to use subsequently acquired language to describe preverbal experiences. This issue was addressed experimentally in this investigation using a novel paradigm. Two-year-old children who lacked color words were individually taught to activate a bubble machine by selecting a particular color of bubble…

Describes a developmental study of semantic structure. (JMB)

Preschool children judged the larger of pairs of stimuli. Three-year olds responded with above-chance accuracy, while 4- and 5-year olds defined "big" as "tall." (ST)

Two predictions based on H. Clark's and E. Clark's hypotheses of the acquisition of word meanings were tested: (1) when learning words which have both spatial and temporal meanings, children will understand the spatial meanings first, and (2) children understand the positive member of an antonym word pair before they understand the negative…

Young children's comprehension and overdiscrimination of natural language concepts were examined by asking 2- and 4-year-old children to select pictorial instances of five concrete semantic concepts. Results suggest that young children initially tend to use concept labels in a very restricted manner. (JMB)

Investigated the interpretation of the word "big" by 40 children of 3 to 5 years. The type and orientation of objects used in the study were varied. Results demonstrated that contextual factors influenced children's responses. (RJC)

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

Examines the development of infants' ability to begin recognizing novel referents of common object names. In particular, the present experiment investigated the development of 12- to 20-month-old infants' ability to infer that an unfamiliar but categorically related object can be designated by a newly learned name for the object class.

In a series of five experiments, young children (two- and three-year-olds) were presented with novel objects in which perceptual and functional features varied independently. Results indicate that early conceptualizations and word meanings are perceptually based when perceptual and functional features are independently available. (Author/RH)

Compares two types of semantic development (the acquisition of disappearance words and success-failure words) to performance on two types of cognitive tasks (object-permanence and means-ends tasks) among infants. (HOD)

Studies 40 children ages 1 to 3 with respect to stage 6 object permanence, representational language, and symbolic play. Examines methodological problems in investigations of Piaget's model of cognitive-linguistic relationships related to the definition of these variables and associated with the use of correlations for data analysis.
