Difficulties with picture naming tasks are associated with literacy problems. When given naming tasks, children with dyslexia are slower to produce words and have a higher proportion of errors (M. Wolf & P. G. Bowers, 1999). However, little is known about the relation between literacy and naming in other populations. This study investigated this…

In this article, the authors examined changes in the usage of muscular and motion-dependent moments during the long-term practice of a complex, multijoint movement. Seven participants practiced a cyclic movement of the upper limbs until their joint angular movements conformed to those of an expert. The motions of the participants were digitally…

One of the author's main goals as a teacher is to impart the skills necessary for students to be successful in science, and that means teaching them how to think and write like scientists. At times, though, it seemed as though the author had exhausted all avenues without ever reaching this goal. At the beginning of each year, she starts her…

In this paper, the term 'intelligence current' is further explained and the problems found in relationships between (among) creativity, intelligence, attitude and environmental factors are discussed, according to the systematic model of creativity previously developed by the author. In this model, the performance of an individual's creativity is…

The process of construction of meanings for the concepts of concentration and neutralization is explored in terms of "contextualizing practices" (Lemke, 1990, "Talking Science. Language, Learning and Values," Norwood, NJ: Ablex) creation of meanings through connections established among actions and their context. This notion is expanded to include…

This study investigated the relationship between narrative skills and theory of mind for low-income children. Two groups of low-income preschoolers, one African American (n = 33) and one European American (n = 36), created a narrative and participated in a false belief task. The European Americans outperformed African Americans on the false belief…

Analysis of students' work on tasks relating to reflections, translations and rotations is discussed. Findings from research with regard to students' understanding of a subject would help teachers prepare for the class.

We report five cases with caudate infarction due to Heubner's recurring artery occlusion, in which we conducted detailed memory examinations in terms of explicit memory and implicit memory. We performed the auditory verbal learning test as explicit memory tasks, and motor and cognitive procedural memory tasks, developed by Komori, as implicit…

There is a change in false belief task performance across the 3-5 year age range, as confirmed in a recent meta-analysis [Wellman, H. M., Cross, D., & Watson, J. (2001). Meta-analysis of theory mind development: The truth about false-belief. "Child Development," 72, 655-684]. This meta-analysis identified several performance factors influencing…

Recent data (T. J. Perfect, C. J. A. Moulin, M. A. Conway, & E. Perry, 2002) have suggested that retrieval-induced forgetting (RIF) depends on conceptual memory because the effect is not found in perceptually driven tasks. In 3 experiments, the authors aimed to show that the presence of RIF depends on whether the procedure induces appropriate…

Life span developmental profiles were constructed for 305 participants (ages 4-95) for a battery of paced and unpaced perceptual-motor timing tasks that included synchronize-continue tapping at a wide range of target event rates. Two life span hypotheses, derived from an entrainment theory of timing and event tracking, were tested. A preferred…

"In his commentary to our paper on the use of knowledge, skill, and ability statements in developing credentialing examinations (Wang, Schnipke, & Witt, 2005 )," Dr. LaDuca set forth his concerns while commending our paper for providing helpful insights into the importance of careful delineation of KSAs. We believe that there is little substantive…

Sex differences on language and visuospatial tasks are of great interest, with differences in hemispheric laterality hypothesized to exist between males and females. Some functional imaging studies examining sex differences have shown that males are more left lateralized on language tasks and females are more right lateralized on visuospatial…

We tested the effect of local lexical ambiguities while manipulating the type of prosodic boundary at which the ambiguity occurred, using French sentences and participants. We observed delayed lexical access when a local lexical ambiguity occurred within a phonological phrase (consistent with previous research; e.g., '[un chat grincheux],'…

Many deaf children and adults show lags in mathematical abilities. The current study examines the basic number representations that allow individuals to perform higher-level arithmetical procedures. These representations are normally present in the earliest stages of development, but they may be affected by cultural, developmental, and educational…
