The facial expressions of twenty-eight 13-month-old middle-class children were videotaped during the 3-minute separation episode of the Ainsworth strange-situation procedure. Anger was the dominant negative emotion expressed by the majority of children; patterns of emotion expression varied with type of attachment; and the proportion of time anger…

Kim (1985) found that both English-speaking and Korean-speaking children find true negative sentences more difficult to verify than false negative sentences. A closer examination of the findings reveals that the difficulty is greater among Korean-speaking children. (Author/RH)

Replies to Akiyama's critique, pointing out areas of agreement between the Kim and Akiyama studies and areas of disagreement. Concludes that, contrary to Akiyama's argument, the Kim (1985) data would not directly challenge the cognition primacy hypothesis in any serious manner. (RH)

Describes two experiments that examined word recognition processes of second, fourth, and sixth graders. Shows that older children use meaning frequency to narrow the amount of information kept active following word recognition. (HOD)

Assesses the interrelations among the functional properties of maternal speech, the structural properties of maternal speech, and child language growth for a period of six months for 22 two-year-old children and their mothers. (HOD)

Describes two experiments comparing how children evaluate three types of uninformative messages (ambiguous, incomplete, inconsistent) and whether and why the speaker's age affects the evaluation of each. (HOD)

Investigates differences in the language learning environments of six twin pairs and 12 singleton toddlers (all firstborn) with special reference to pragamatic factors that might be expected to differ in dyadic and triadic interactive situations. (HOD)

Examines the ability of 30 normal and 30 learning disabled children across a three-year period to understand a sequence of instructions, communicate the steps in a sequence to others, and rephrase their verbal messages through a referential communication task. (HOD)

Explores the relations among combinatorial capacities in language, symbolic play, blockbuilding, and nonsemantic action sequences within a sample of 18- to 24-month-old children, as well as assessing the developmental level of a selected subset of concepts. (HOD)

Reports the results of cognitive test performance and early childhood activities in individuals with congenital adrenal hyperplasia, an autosomal recessive disorder associated with elevated prenatal adrenal androgen levels, demonstrating the effects of early exposure to excess androgenizing hormones on sexually dimorphic cognitive functioning.…

Compares the Genevan and Cattell-Horn theories of intelligence and describes both similarities and differences. Describes a study investigating the relation of the Piagetian operative level to the child's ability to use crystallized solution procedures (aids) in making elementary numerical comparisons. (HOD)

Investigates the problem young children have in constructing diagonals, noting that, on the whole, they can not make diagonals in the horizontal/vertical configuration. (HOD)

Reports on a study in which children aged 7 to 9 years and 11 to 13 years were asked to judge which one out of three wooden blocks would float, given weight and volume information for each block relative to a block that was known to float. Indicates that judgments may have been based on the size-weight illusion. (HOD)

Considers the life stages of the Black extended family; research on the antecedents and consequences of extended family life; and social policy, clinical intervention, and family research implications of the Black extended family from the context of a broad conceptual and methodological definition of family. (HOD)

Investigates whether an experimentally imposed 80dB (A) noise affected psychomotor, serial memory words and pictures, incidental memory, visual recall, paired associates, perceptual learning, and coding performance of five-year-old Black children attending day care centers near and far from elevated subways. (HOD)
