正常与多动儿童的创造力、学习适应性比较研究

本研究比较ADHD儿童和正常儿童在创造性思维测验、学习适应性测验以及教师对其创造力评价上的差异。结果表明：(1)ADHD儿童和正常儿童在数字和图形创造性思维测验上的成绩没有显著的差异。表明ADHD和创造力是彼此独立的两个特质;(2)ADHD儿童在学习态度、学校环境(主要是师生关系和同伴关系)、独立性和毅力等维度上明显偏低;(3)不同学科教师对于ADHD儿童和正常儿童在创造力水平高低的评价上没有显著性差异;(4)对于正常儿童。不同学科教师对其创造力的评价与儿童在创造力测验上的得分呈显著性相关;对于ADHD儿童则没有显著性相关。

Face encoding is not categorical: Consistent evidence across multiple types of contingent aftereffects

ABSTRACT

Race-contingent aftereffects indicate that faces of different races are encoded via dissociable visual channels. Race-contingent aftereffects reflect perceptions of typicality, indicating a gradual transition of activity across channels as faces change from looking more typical of one race to the other We examine whether faces forming more discrete categories (sex: male/female; species: human/monkey) are encoded in a similar fashion, or whether they are instead encoded via more dichotomous categorical judgements. Curves representing the rate of change of aftereffect magnitude as stimuli changed from male to female produced shallow slopes, closely resembling ratings of typicality, but differing significantly from slopes for categorical judgements. For species, aftereffect slopes were significantly shallower than both ratings of typicality and categorical judgements. Overall, these results suggest that the encoding of facial properties such as these is not categorical, but instead involves a graded response as stimulus typicality varies. Aftereffect slopes were similar across the two experiments, raising the possibility of a common system that is recruited during contingent adaptation, regardless of the specific dimension involved or the categories used by the experimenter.     

The role of working memory in auditory selective attention

A growing body of research now demonstrates that working memory plays an important role in controlling the extent to which irrelevant visual distractors are processed during visual selective attention tasks (e.g., Lavie, Hirst, De Fockert, & Viding, 2004). Recently, it has been shown that the successful selection of tactile information also depends on the availability of working memory (Dalton, Lavie, & Spence, 2009). Here, we investigate whether working memory plays a role in auditory selective attention. Participants focused their attention on short continuous bursts of white noise (targets) while attempting to ignore pulsed bursts of noise (distractors). Distractor interference in this auditory task, as measured in terms of the difference in performance between congruent and incongruent distractor trials, increased significantly under high (vs. low) load in a concurrent working-memory task. These results provide the first evidence demonstrating a causal role for working memory in reducing interference by irrelevant auditory distractors.     

Working memory capacity and visual attention: Top-down and bottom-up guidance

Previous studies have indicated that working memory capacity (WMC) is related to visual attention when selection of critical information must be made in the face of distraction. The present study examines whether WMC-related differences in flanker task performance might be decreased by displays that are designed to support bottom-up guidance of attention. Participants were required to respond to a centrally located target while ignoring a peripheral flanker. In one condition, bottom-up support was provided by embedding the target in a row of zeros. In another condition, the zeros were removed, thus emphasizing the role of top-down attention in selecting spatially defined information. It was found that the inclusion of zeros led to the elimination of WMC-related flanker effects. We conclude that bottom-up attentional guidance can attenuate the role of WMC in selective attention.     

Nursing Home Adaptation in Visually Impaired Older Adults Using a Narrative Approach1,2

This study used a narrative approach to examine the difficulties that older visually impaired people experience when adapting to life in a nursing home. The interview data were collected from one blind aged person (n = 1), focusing on the adaptation process from moving into the nursing home to the present and maintaining context of narrative that included the life history. Subcategories were extracted based on a framework of temporal coherence, causal coherence, thematic coherence, and situational coherence. This study revealed three factors related to adaptation to life in a nursing home for a visually impaired person, including psychological adaptation: becoming accustomed to life in the facility after changes in the living environment, having gratitude and maintaining “moderating human relationships,” and participating in activities connected to one's purpose in life. He was able to psychologically adapt and came to accept his death through an awareness of aging.     

One-encounter search-image formation by araneophagic spiders

An experimental study of search-image use by araneophagic jumping spiders (i.e., salticid spiders that prey routinely on other spiders) supports five conclusions. First, araneophagic salticids have an innate predisposition to form search images for specific prey from their preferred prey category (spiders) rather than for prey from a non-preferred category (insects). Second, single encounters are sufficient for forming search images. Third, search images are based on selective attention specifically to optical cues. Fourth, there are trade-offs in attention during search-image use (i.e., forming a search image for one type of spider diminishes the araneophagic salticids attention to other spiders). Fifth, the araneophagic salticids adoption of search images is costly to the prey (i.e., when the araneophagic salticid adopts a search, the preys prospects for surviving encounters with the araneophagic salticid are diminished). Cognitive and ecological implications of search-image use are discussed.     

Autonomy and Relatedness among Chinese Sojourners and Applicants: Conflictual or Independent Predictors of Well-Being and Adjustment?

Self-Determination Theory argues that relatedness and autonomy represent innate and universally critical needs and that, when satisfied, both needs should yield an independent positive effect on well-being and adjustment for all individuals. In contrast, some cross-cultural perspectives suggest that the pursuit of autonomy hampers the development of satisfying relationships, and such conflicts might be especially problematic for the well-being of individuals in collectivistic societies that value social bonds over the pursuit of uniqueness and independence. The present study sampled Chinese students who had temporarily moved to Belgium to study (i.e., sojourners) and Chinese students involved in the application procedure to study in Belgium (i.e., applicants). Consistent with SDT, the present research shows that the basic psychological needs for autonomy, relatedness, and competence are positively interrelated, that the satisfaction of these three needs predicts unique variance in Chinese students’ psychological well-being, vitality, and depression (i.e., main effects), and that autonomy satisfaction yields a more beneficial effect on vitality and better protects against depressive feelings when relatedness satisfaction is low (i.e., an interaction effect). Finally, mean-level differences in well-being between Chinese sojourners and applicants could be fully accounted by differential need satisfaction.

Top-down contingent capture by color: evidence from RT distribution analyses in a manual choice reaction task

According to the contingent capture hypothesis, observers can specify their control settings in advance of the target’s presentation to quickly attend to relevant target colors. Two predictions were derived from this hypothesis and tested in a manual choice response task. First, contingent capture by color was expected: capture of spatial attention by a better-matching color stimulus should be stronger than capture by a less-matching color stimulus. Second, with the control settings specified in advance, the contingent capture by color should commence early after the stimulus onset and should be evident among fast correct responses in an RT distribution. Both predictions are shown to hold true in two experiments. Results are discussed in light of contrasting evidence for saccadic instead of manual responses.
