Adults and children three, four, five, and six years of age were asked to complete statements by choosing a word from the following word pair alternatives: metaphorical/literal, literal/anomalous, and metaphorical/anomalous. A categorization task was used to determine how subjects viewed relationships among items. (Author/RH)

The classifying behavior of five-year-old children and adults was examined in two studies of restricted classification using triads of stimuli composed of the dimensions of length and density. Results were consistent with the notion of separable perception for adults and integral perception for children. (Author/SS)

In two separate task conditions, cells of a matrix could be filled either by taking account of only one dimension or by considering both dimensions. Subjects were 80 children 3 to 6 years of age. The majority of three-year-olds failed the two-attribute condition and there was a significant interaction between age and experimental condition.…

Investigated multiple coding for children of different ages and tested the generality of strategy effects obtained in single code studies for multiple coding. (Author/DB)

Three studies examined early development of recall. Children between 2 years 9 months and 5 years of age were tested on nine-item lists containing three objects from each of three conceptual categories or nine objects for nine different conceptual categories. (Author/SS)

Examined acquisition of the mass/count distinction in English. Results indicated that at 7 years bilinguals did not infer from the linguistic context whether new nouns referred to objects or a substance. By 9 years, bilinguals who were strong in English responded similarly to monolingual peers, but bilinguals with lower English abilities still…

Four-, 6-, and 8-year olds were shown a test picture of three related objects and two target pictures of three objects in the same or different relation. Older subjects, but not 4-year olds, identified the relationally similar target picture when the test and target also differed in dimensions of size or color saturation and in direction of size…

Five experiments involving children of 4-11 years investigated partonomic knowledge and its relation to the use of taxonomic organization. Results suggest that children are sensitive to parts of common objects and appear to be able to use this sensitivity to group objects in abstract, function-based, superordinate categories. (RJC)

Investigates the knowledge of thematic and taxonomic relations of 15 children of 26 months and 24 children of 34 months. Both age groups were able to identify thematic matches. However, 34-month-olds were able to recognize a wider range of thematic associations than 26-month-olds. (RJC)

Tested 7 and 10 month olds for perception of correlations among facial features. After habituation to faces displaying a pattern of correlation, 10 month olds generalized to a novel face that preserved the pattern of correlation but showed increased attention to a novel face that violated the pattern. (BC)

The matching-to-sample performances of three young adults with autism and four children (ages four to nine) without intellectual disabilities were examined in three experiments using complex sample stimuli. Results for all subjects showed that each of two redundant relevant sample elements and their respective comparison stimuli were substitutable…

The ability of 31- to 36-month-old children to act in accordance with rules was assessed in 2 slightly different experiments using sorting tasks and knowledge tasks. Taken together, the results of both experiments imply a relatively rapid, age-related change culminating in the ability to systematically execute rules that require access to extant…

Three studies explored 2- to 4-year-olds' ability to categorize objects based on novel underlying causal power. Children saw that a "blicket" would set off a machine and participated in categorization, induction, and association tasks. Results demonstrated that even 2-year-olds easily learn about an object's new causal power and…

Examined causal status effect (weighing cause features more than effect features in categorization). Presented adults and 7- to 9-year-olds animal descriptions wherein one feature caused two others. Asked which transfer item was more likely an example of novel animal. Found that both groups preferred an animal with a cause and an effect feature…

Relational similarity connects superficially dissimilar objects and events. In 2 experiments, the ability to recognize and respond to similar relations was studied in children ages 3 to 5 with 2 comparison tasks. Children interpreted illustrated pictures that shared perceptual or relational aspects and then made 2 comparison choices and…
