Jigsaw puzzles are ubiquitous developmental toys in Western societies, used here to examine the development of metarepresentation. For jigsaw puzzles this entails understanding that individual pieces, when assembled, produce a picture. In Experiment 1, 3- to 5-year-olds (N = 117) completed jigsaw puzzles that were normal, had no picture, or…

The purpose of this study was to investigate the influence of cognitive training (CT) using mobile applications on attentional control and impulsivity among pre-service teachers. Pre-service teachers were divided into two groups: experimental (n=25) and control (n=14) groups, they were selected from a large sample (n=718). Over 28 sessions, the…

Analogical reasoning is essential for transfer by supporting recognition of relational similarity. However, not all analogies are created equal. The source and target can be similar (near), or quite different (far). Previous research suggests that close comparisons facilitate children's relational abstraction. On the other hand, evidence from…

We often hear that the most important role of education is to teach children to think creatively and effectively. Singapore Ministry of Education (MOE) has recognised the importance of nurturing children from young and aimed to shift from "academic rote learning" to more experiential learning. Since 2003, mandated nationwide skill…

The present study explores the effects of parental scaffolding of children's problem solving on the development of executive function (EF). Eighty-two children were assessed at 2, 3, and 4 years of age on a variety of EF tasks and, at ages 2 and 3, on a problem-solving puzzle with which parents offered structured assistance (i.e., scaffolding).…

This study explored preschool age and gender differences in help-seeking within the theoretical framework of scaffolded problem-solving and self-regulation (Bruner, 1986; Rogoff, 1990; Vygotsky, 1978; 1986). Within-subject analyses tracked changes in help-seeking among 62 preschoolers (34 boys, 28 girls, mean age 4.22 years) solving a challenging…

The relationship between preschoolers' puzzlemaking strategies and part-whole perception was investigated in the present study. Forty-eight two year olds and 48 four year olds were randomly selected from eight licensed childcare centers. Puzzlemaking strategies (image, form, color, and trial and error) were measured by performance in the…

Reports observations of the use of mental aerobics with 48 adults whose median age was 70. Provides examples of the group puzzles and logic, math, and word problems used to enhance cognitive functioning and creative thinking. (SK)

States that puzzles are an important tool in helping children engage in the problem-solving process. Claims that children are interested in puzzles because they can be active as observers, problem solvers, and learners, with little or no assistance from adults and others. Defines nine characteristics of good puzzle-making situations. (MOK)

The authors apply descriptive and sequential analyses to a mother's distancing strategies toward her 3-year-old twin sons in puzzle assembly and book reading tasks. One boy had normal hearing and the other a mild hearing loss (threshold: 30 dB). The results show that the mother used more distancing behaviors with the son with a hearing loss, and…
