Only one previous developmental study of Stroop task performance (Schiller, 1966) has controlled for differences in processing speed that exist both within and between age groups. Therefore, the question of whether the early developmental change in the magnitude of Stroop interference actually persists after controlling for processing speed needs…

Spatial reasoning, recognised as playing a critical role across STEM disciplines, is gaining prominence in mathematics education, not only as fundamental to mathematics, but also as embodied mathematical activity. In this paper, we discuss spatial reasoning and its embodiment in mathematics. We then present a systematic review of the topics as…

Identifying change at the individual level is an important goal for researchers, educators, and clinicians. We present a set of statistical procedures for identifying individuals who depart from a normative change. Using Latent Change Scores models (LCS), we illustrate how the Individual Likelihood computed from a statistical model for change…

While behavioral and educational data characterize a fourth grade shift in reading development, neuroscience evidence is relatively lacking. We used the N400 component of the event-related potential waveform to investigate the development of single word processing across the upper elementary years, in comparison to adult readers. We presented…

Several models assume that working memory development depends on age-related increases in efficiency and speed of processing. However, age-related increases in the efficiency of the mechanisms that counteract forgetting and restore memory traces may also be important. This hypothesis was tested in three experiments by manipulating both the…

Previous research has indicated that boys and girls differ in the ways they display aggression and experience victimization. This study examined the ability of American children to correctly differentiate between various forms of aggressive acts and pro-social behavior. The results indicate that though there appear to be developmental differences…

Argues that New Hampshire high-stakes test administered at the end of the third grade is flawed and thus should be discontinued because the questions are not only too abstract, but beyond the knowledge and experience of most third graders. (Contains 23 references.) (PKP)

Results of two experiments support the finding of developmental change in the role of representation in perspective-taking tasks. Experiment 1, which involved 80 first-grade students with a mean age of 6.5 years, crossed task characteristics and response modes. Subjects either imagined an observer's movement around a fixed array or imagined an…

Positively correlated were verbal fluency scores and scores for strategies expected to distinguish levels of verbal fluency among 64 third-graders and 71 sixth-graders. When a smaller sample of similarly aged students completed expanded versions of tasks, results revealed grade and gender differences in strategy use and level of task performance.…

Three studies investigated developmental changes in immanent justice responding by asking participants to respond to vignettes in which a person's bad behaviour was followed by a negative consequence. Study 1 consisted of 152 sixth graders and 128 college students and presented participants with a vignette that examined the notion of bad people…

The authors measured memory for individual features (objects only or locations only) and the combination of those features (objects and locations) in 9-, 12-, and 21-year-old students with a "yes" or "no" recognition task. Analysis of recognition memory performance (d' scores) revealed that although age differences existed in memory for individual…

Third and fifth grade children (average age 8.6 and 10.6 years) and adult participants were tested with printed words of varying length in a new on-line identification task (the luminance increment paradigm, LIP) and a speeded naming task. Effects of general length (length in letters, phonemes and syllables) were shown to decrease systematically…

Testwise responses of grade-school students to multiple-choice science items and the intercorrelations between different testwiseness skills were examined in this document. A total of 134 third-grade, 133 fifth-grade, and 143 sixth-grade students from two elementary schools in a large suburban school district in Utah responded to 60 science items…
