Ninety-seven children aged 4-11 (49 males, 48 females, mostly White) were given the opportunity to improve their problem-solving performance by devising and implementing a novel cognitive offloading strategy. Across two phases, they searched for hidden rewards using maps that were either aligned or misaligned with the search space. In the second…

Fraction knowledge and algebraic skill are closely linked. Algebra is a gatekeeper for advanced courses (Booth & Newton, 2012; Brown & Quinn, 2007). This study uses the person-centered approach of latent profile analysis to examine individual differences in middle schoolers' (N = 350) algebra performance at the end of the year (EOY). The…

Both between- and within-group differences in children ages nine to eleven identified as having reflective or impulsive cognitive tempos. Cognitive tempo was first assessed using Kagan's Matching Familiar Figures test, and children were later tested on the Raven's Standard Progressive Matrices. (Author/RH)

Subjects categorized as either players who displayed make-believe in natural free-play situations or nonplayers whose behavioral repertoires did not include make-believe, were exposed to either a free-play, an imitation or a problem-solving condition and given an alternate-uses test. Free-play enhanced associative fluency among players who engaged…

It may be concluded that reflective and fast-accurate Ss differ from impulsive Ss of the same grade in the strategies used to solve problems. These strategy differences may or may not lead to more efficient performance, depending on the structure of the task, but they are indicative of different levels of cognitive development. (Author)

Two studies were conducted with 8- and 10-year-old children to examine sources of age and skill differences in verbal analogical reasoning. Discussion focuses on the child's "problem space" for the analogy task and possible differences in task understanding that lead to strategy and process differences in older versus younger and skilled versus…

Reflective and impulsive children were instructed to hasten or delay their responses on a test of hypothesis-seeking and constraint seeking conceptual strategies. Latency of response data on pretesting, training, and immediate posttests showed that the attempts to hasten or delay responses were successful in changing response latencies. (ST)

It was concluded that in grade school children the tendency to be reflective in problem solving also entails a disposition to take longer in making decisions. (Author)

According to Hypothesis (H) theory, learning should be very difficult when the number of Hs the subject samples from is very large and/or the correct H is not available. These assumptions were tested with third- and fourth-grade children. In general, results supported these assumptions. (Author/MP)
