Piaget's theory of stage structure is synonymous with discussions involving cognitive development. As with any theoretical model, researchers inevitably and rightly seek to affirm and/or contest the elements of the model presented. In this comparative study, students' performance across three hands-on engineering tasks for two distinct student…

The middle school transition has been identified as a difficult time for youths, resulting in adjustment difficulties across a variety of domains. Although some research has examined strategies that are useful for the adjustment outcomes associated with the transition, more research understanding student perceptions of what is helpful in the…

This article is concerned with the influences that are brought to bear on the design of school buildings and the effects that the design of these buildings have on those who teach and learn in them. The article also focuses on the ways in which design is altered in and through the practices of these occupants. We argue that there is a mutual…

Three experiments investigated effects of complexity on 2- to 6-year-olds' understanding of a beam balance. Found that 2- to 4-year-olds succeeded on problems that entailed binary relations, but 5- and 6-year-olds also succeeded on problems that entailed ternary relations. Ternary relations tasks from other domains (transitivity and class…

Students (n=150) ages 11, 14, and 17 were asked to explain the meanings of 24 different idiomatic expressions. Performance on the task gradually improved as subject age increased. High-familiarity idioms were easier to explain than moderate-familiarity or low-familiarity expressions. Easier idioms tended to be more transparent. (Author/JDD)

Eleven preschool children with Down Syndrome were taught new words/graphic symbols (Rebus or modified Bliss) using various treatment conditions. Incorporation of graphic symbols into language intervention programs may facilitate language acquisition, provided the tasks and procedures are appropriate to the child's developmental age and level of…

The purpose of this study is to see if older adults who experience problems with thought suppression tend to encounter greater difficulty deriving a sense of meaning in life. Data from a longitudinal nationwide survey of older people (N = 988) indicate that greater difficulty with thought suppression is associated with a decline in meaning over…

This study examined the hypothesis that age-related increases in reasoning ability are associated with the ability to represent relations of increasing complexity, defined as the number of entities related. The study's purpose was to determine the extent to which this ability to process relations with three entities increased between ages 4 and 8…

To examine how young children learn to read new words, we asked preschoolers (N = 115, mean age 4 years, 8 months) to learn and remember novel spellings that made sense based on letter names (e.g. TZ for "tease") and spellings that were visually distinctive but phonetically inappropriate. Children who were more knowledgeable about letter names…

Context analysis of 10 adolescent novels revealed that the primary female characters of pre-1971 novels attempted only low-level tasks which involved self-concern and peer relationships. The primary female characters in post-1980 novels attempted tasks of practical and abstract skills that involved planning for the future. (BB)
