The development of the concept of seriation was studied for 415 children, ranging in age from 3 to 9 years. The subjects were required to learn to identify the larger or smaller object in a two stimulus series, the smallest or middle-sized object in a three stimulus series, and the largest or next to the smallest in a four stimulus series. The end…

Metaphors of similarity and proportionality, together with a pictorial form of similarity metaphors, proverbs, and several Piaget-type cognitive tasks, were given to 50 boys aged 5 through 13 years. Results indicated that metaphor comprehension is a type of classificatory behavior, the development of which is related to maturing cognitive…

Explores age differences in children's conceptions of play, pretending, and toys. Examines parallel structural changes in other areas of development, such as language acquisition. Subjects for the study were 5-, 7-, 9-, and 11-year-old children. (BD)

Learning of the concept of horizontality by fourth graders was investigated. Comparisons by age and sex were made. (BB)

Developmental changes in a variety of cognitive processes as a function of age and schooling were examined in 160 rural Guatemalan children aged 5, 7, 9 and 11 years. (BD)

Presents a study of the development of self-recognition in infants from 6 to 24 months of age. The development of self-recognition is compared to the development of object permanence. (BD)

Dissimilarity judgments of all possible pairs of 10 animal names were obtained from first-, third-, and sixth-grade children, and college students. Analysis with multidimensional scaling procedures revealed a semantic space consisting of the features of size, domesticity, and predativity. (Author/JMB)

Two sets of tasks designed to measure operational thinking and the problem-finding skill of asking general questions were administered to 7-, 9-, and 11-year-old children. Analyses performed on the quality of the children's questions revealed developmental trends consistent with earlier work on problem finding. (Author/JMB)

A sample of 355 first-, third-, and fifth-grade children from a middle-class school were asked to rate each of 40 adult occupations as male, female, or neutral, in terms of their attitudes about which sex has the abilities to do each job. (Author/JMB)

Endel Tulving's distinction between "episodic" and "semantic" memory defines age differences in word association norms more comprehensively than the usual syntactic classifications. As subjects mature the principal development is an episodic-semantic shift. Young children associate primarily with the stimulus' perceived…

According to Humean framework, relations are judged to be causal to extent that they are characterized by regularity, continuity, and covariation among college students and college-bound 11- and 14-year-olds. Presents subjects with information about one of the following indices: potential causal factor covaried with effect and potential causal…

Examines the ability of six- and eight-year-old children to hide and recover 20 marbles in a large room containing 100 possible sites. Shows that children tend to concentrate activities in sections of the room and are sensitive to clusters of proximal sites. (HOD)

Two studies assessed the ability of two groups of preschool children (ages two to four and three to five years, respectively) to label and categorize age groups on the basis of photographs and dolls representing the life span. Results indicated age and sex differences. (Author/CI)

In this developmental study of sustained cognitive monitoring, second graders, sixth graders, and college students followed a two-part sequence of spatial directions and then made judgments about reaching the destination intended by direction giver. Cognitive monitoring skills of the type examined appear to be useful in many real-world cognitive…

Descriptions of television's typical good and bad guys as seen by first, third, and fifth graders demonstrate that television offers a limited repertoire of good guy characteristics, and indicate important age related differences in judgments on television characters. Emphasizing relationships could provide more multidimensional information on…
