Moderators of the Exercise/Feeling-State Relationship: The Influence of Self-Efficacy, Baseline, and In-Task Feeling States at Moderate- and High-Intensity Exercise

The present study examined the moderating influence of self-efficacy, baseline feeling states, and in-task feeling states on exercise-related feeling-state changes at moderate- and high-intensity exercise. Physically active females ( N = 60) participated in 1 of 5 conditions: (a) attention control for 30 min, (b) exercise at 50% heart rate reserve (HRR) for 15 min, (c) exercise at 50% HRR for 30 min, (d) exercise at 85% HRR for 15 min, and (e) exercise at 85% HRR for 30 min. The Exercise-Induced Feeling Inventory (EFI; Gauvin & Rejeski, 1993) was completed pre-, during, and post-exercise, while self-efficacy was completed pre-exercise. Multilevel modeling (Bryk & Raudenbaush, 1992) revealed that pre-exercise self-efficacy and in-task tranquility moderated the change in tranquility for high-intensity exercise. Furthermore, baseline feeling states moderated the change in all 4 feeling states. It is recommended that baseline and in-task feeling states and self-efficacy be considered when examining high-intensity exercise.     

A Web-accessible database of characteristics of the 1,945 basic Japanese kanji

In 1981, the Japanese government published a list of the 1,945 basic Japanese kanji (Jooyoo Kanjihyo), including specifications of pronunciation. This list was established as the standard for kanji usage in print. The database for 1,945 basic Japanese kanji provides 30 cells that explain in detail the various characteristics of kanji. Means, standard deviations, distributions, and information related to previous research concerning these kanji are provided in this paper. The database is saved as a Microsoft Excel 2000 file for Windows. This kanji database is accessible on the Web site of the Oxford Text Archive, Oxford University (http://ota.ahds.ac.uk). Using this database, researchers and educators will be able to conduct planned experiments and organize classroom instruction on the basis of the known characteristics of selected kanji.     

Long-term memory for pictures and sentences

Two experiments were conducted to examine the fan effect in recognition memory for pictures and sentences. Subjects in the first experiment memorized sets of pictures (N= 13) or sentences (N=13) in which the study items comprised concept combinations (e.g., the clock is on the television) that could be unambiguously depicted in each modality. The fan effect, contrasting study items involving unique- and shared-concepts combinations, was observed in the recognition reaction time data for sentences but not for pictures. Subjects in the second experiment (N= 17) memorized sets of pictures and sentences in which, in addition to the unique and shared intramodality conditions used in Experiment 1, subjects memorized items in each modality that shared concepts with items in the alternative modality. Although the fan effect was reduced for sentences in the second experiment, the intramodality results were qualitatively comparable to those obtained in Experiment 1. The results in the intermodality conditions indicated that, although pictorial study items influenced reaction time to sentences with which they shared a concept, the reverse was not the case. The results were thought to be inconsistent with the view that pictures and sentences enjoy a common representational format in long-term memory.     

Complex Trauma in Children and Youth: A Scoping Review of Sensory-Based Interventions

Emerging evidence in neuroscience indicates exposure to complex trauma in children and youth affects brain development—particularly with the ability to process sensory information. This sensory processing challenge has been shown to negatively impact emotional and self-regulation. A developing area of trauma treatment utilizes sensory-based interventions to target these concerns. A scoping review of the literature indicates there is limited, although promising, evidence for the use of these interventions when used as part of an integrated treatment approach. Occupational therapy is in a unique position to contribute to this area of practice due to a background in sensory-based approaches.     

Basis of recency and frequency judgements of novel faces: generalised strength or episode-specific memories?

Evidence for generalised and episode-specific strength in judgements of recency and frequency of novel faces was investigated in two experiments. Novel faces (created using an identikit program) were presented either once or three times in either of two study sets, separated by a 4 minute (Experiment 1) or 24 hour (Experiment 2) delay. In Experiment 2, the study-test phases were preceded by a familiarisation phase in which faces were presented either with or without an occupational label (some faces were not familiarised). In both experiments, judgements of recency were consistent with greater reliance on generalised strength (an amalgamation of recency and frequency of presentation), although there was some evidence for a contribution of episode-specific information. Familiarisation had opposite effects on judgements of recency and frequency, with familiarised faces judged as having been studied more frequently (three times), but less recently (yesterday) than unfamiliarised faces. The latter result is consistent with participants discounting generalised strength when episode-specific information is inadequate.     

Genetic and environmental structure of Cloninger's temperament and character dimensions

The multivariate genetic and environmental structure of Cloninger's Temperament and Character Inventory (TCI) was investigated in a sample of 617 pairs of adolescent and young adult twins from Japan. Additive genetic factors accounted for 22% to 49% of the variability on all TCI temperament scales. Although the theory predicts lower heritability for the character scales, all character subscales had a substantial genetic contribution, and nonshared environmental influences accounted for the remainder. Multivariate genetic analyses showed that several subscales used to define one dimension shared a common genetic basis with subscales defining others. Using the degree of shared genetic influence as the basis to rearrange the TCI subscales into new dimensions, it was possible to create genetically independent scales. The implications for personality measurement, theory, and molecular genetic research are discussed.     

Working memory and literacy as predictors of performance on algebraic word problems

Previous studies on individual differences in mathematical abilities have shown that working memory contributes to early arithmetic performance. In this study, we extended the investigation to algebraic word problem solving. A total of 151 10-year-olds were administered algebraic word problems and measures of working memory, intelligence quotient (IQ), and reading ability. Regression results were consistent with findings from the arithmetic literature showing that a literacy composite measure provided greater contribution than did executive function capacity. However, a series of path analyses showed that the overall contribution of executive function was comparable to that of literacy; the effect of executive function was mediated by that of literacy. Both the phonological loop and the visual spatial sketchpad failed to contribute directly; they contributed only indirectly by way of literacy and performance IQ, respectively.
