Theories accounting for the development of analogical reasoning tend to emphasize either the centrality of relational knowledge accretion or changes in information processing capability. Simulations in LISA (Hummel & Holyoak, 1997, 2003), a neurally inspired computer model of analogical reasoning, allow us to explore how these factors may collaboratively contribute to the development of analogy in young children. Simulations explain systematic variations in United States and Hong Kong children's performance on analogies between familiar scenes (Richland, Morrison & Holyoak, 2006; Richland, Chang, Morrison & Au, 2010). Specifically, changes in inhibition levels in the model's working-memory system explain the developmental progression in US children's ability to handle increases in relational complexity and distraction from object similarity during analogical reasoning. In contrast, changes in how relations are represented in the model best capture cross-cultural differences in performance between children of the same ages (3-4 years) in the United States and Hong Kong. We use these results and simulations to argue that the development of analogical reasoning in children may best be conceptualized as an equilibrium between knowledge accretion and the maturation of information processing capability.  相似文献

Drawing from self-determination theory, three studies explored the social-environmental conditions that satisfy versus thwart psychological needs and, in turn, affect psychological functioning and well-being or ill-being. In cross-sectional Studies 1 and 2, structural equation modeling analyses supported latent factor models in which need satisfaction was predicted by athletes' perceptions of autonomy support, and need thwarting was better predicted by coach control. Athletes' perceptions of need satisfaction predicted positive outcomes associated with sport participation (vitality and positive affect), whereas need thwarting more consistently predicted maladaptive outcomes (disordered eating, burnout, depression, negative affect, and physical symptoms). In addition, athletes' perceptions of psychological need thwarting were significantly associated with perturbed physiological arousal (elevated levels of secretory immunoglobulin A) prior to training. The final study involved the completion of a diary and supported the relations observed in the cross-sectional studies at a daily level. These findings have important implications for the operationalization and measurement of interpersonal styles and psychological needs.  相似文献

Hypnagogic and hypnopompic (H&H) hallucinations are those experienced on the borders of sleep and waking. Intrusive thoughts have been proposed to relate to the occurrence of such experiences. In a sample of students (N = 299), the present study investigated the relation between auditory and felt-presence H&H experiences, and specific modalities of intrusive thought (auditory and visual) whilst controlling for age, gender, depression, anxiety and thought suppression. The psychometric properties of the Durham Hypnagogic and Hypnopompic Hallucinations Questionnaire (DHQ) were also examined. Exploratory (N = 299) and, in a second sample, confirmatory (N = 502) factor analyses showed good internal and test-retest reliability for the auditory and felt-presence subscales of the DHQ, but not for the visual subscale. Regression analyses indicated that the sole predictor of auditory H&H hallucinations was intrusive auditory imagery, and the sole predictor of felt-presence H&H experiences was intrusive visual imagery. Explanations for these findings are considered and implications for future research are discussed.  相似文献

Protective factors for fostering reasons for living were examined among low-income, suicidal, African American women. Bivariate logistic regressions revealed that higher levels of optimism, spiritual well-being, and family social support predicted reasons for living. Multivariate logistic regressions indicated that spiritual well-being showed unique predictive value for reasons for living. Further, the multivariate model accurately predicted reasons for living 72% of the time. Partial support was found for a cumulative protective model hypothesizing a linear relationship between the number of protective factors endorsed and increased reasons for living. Implications for community-based preventive and recovery-oriented intervention efforts and future research are discussed.  相似文献

This study compared the sensory and perceptual abilities of the blind and sighted. The 32 participants were required to perform two tasks: tactile grating orientation discrimination (to determine tactile acuity) and haptic three-dimensional (3-D) shape discrimination. The results indicated that the blind outperformed their sighted counterparts (individually matched for both age and sex) on both tactile tasks. The improvements in tactile acuity that accompanied blindness occurred for all blind groups (congenital, early, and late). However, the improvements in haptic 3-D shape discrimination only occurred for the early-onset and late-onset blindness groups; the performance of the congenitally blind was no better than that of the sighted controls. The results of the present study demonstrate that blindness does lead to an enhancement of tactile abilities, but they also suggest that early visual experience may play a role in facilitating haptic 3-D shape discrimination.  相似文献

This article reports pre-post intervention results from a randomized controlled trial evaluating the initial efficacy of a couples-based intervention aimed at teaching skills for coping with stress and improving relationship skills in a sample of 173 ethnically diverse low-income co-resident mothers and fathers who were raising at least one child together. Couples were randomly assigned to one of three interventions or to an assessment-only control condition. The Fatherhood, Relationship, and Marriage Education (FRAME) intervention is a 14-h psychoeducation intervention developed specifically to strengthen the ability of low-income mothers and fathers to reduce conflict, cope with stress, and co-parent effectively. Three versions of FRAME were assessed: a men-only group, a women-only group, and a couple's group. The pre-post intervention analyses revealed reductions in financial stress, disengagement coping, and involuntary disengagement responses, as well as improvements in problem solving. These pre-post changes on stress and coping variables were both statistically significant and reliable as assessed by the Reliable Change Index (Jacobson and Truax 1991). Results were particularly strong for the couples' and women's groups. In addition, positive pre-post changes on stress and coping variables were associated with pre-post reductions on symptoms of depression for participants assigned to an intervention. The results demonstrate that participants in FRAME acquire some of the key skills taught in the intervention, and skills acquisition appears to translate into symptom reduction. In addition, this study highlights the value of an intervention aiming to improve the capacity of parents with economic hardship to cope effectively with stress.  相似文献

Purpose

The purpose of this study was to compare the results of a subjective and a statistical method of detecting non-comparable items in 14 language-translated forms of a survey measuring organizational culture.

Design/Methodology/Approach

Data were obtained from a large multinational organization using a 60-item organizational culture survey. Each of 14 language-translated forms were administered to members of their respective language groups and compared to the original English (United States) form. Subjective reviews were conducted using fluent bilingual organizational members whom flagged items they did not believe were comparable. Statistical analyses using an item response theory (IRT) approach were used to detect problematic items from 14 samples with sizes ranging from 304 to 3,014. Detection patterns from these two approaches were compared.

Findings

The subjective approach identified far less items as problematic and did not agree with the statistical approach.

Implications

Our results suggest that the subjective approach as a pre-screening adaptation procedure has little added value over a careful translation/back-translation procedure.

Originality/Value

The use of language-adapted organizational surveys has become increasingly important to multinational organizations. In examining scores from such surveys the establishment of score comparability is essential. IRT analyses are often used to determine whether scores are comparable across language translations. It is also common for subjective reviews of item content to be utilized prior to statistical techniques to determine if the translated items are comparable to the original form. No research known to authors has compared modern statistical and subjective approaches to addressing these issues.  相似文献

Approximately 15% to 20% of women have been victims of rape and close to a third report current rape-related PTSD or clinically significant depression or anxiety. Unfortunately, very few distressed rape victims seek formal help. This suggests a need to develop alternative ways to assist the many distressed victims of sexual violence. Online treatment programs represent a potentially important alternative strategy for reaching such individuals. The current paper describes a pilot evaluation of an online, therapist-facilitated, self-paced cognitive behavioral program for rape victims. Five college women with current rape-related PTSD were recruited to complete the From Survivor to Thriver (S to T) program in a lab setting over the course of 7 weeks. After completing the program, 4 participants reported clinically significant reductions in PTSD symptoms and no longer met criteria for PTSD. All participants reported clinically significant reductions in vulnerability fears and 4 reported significant reductions in negative trauma-related cognitions. Implications of the results for further development of the S to T program and how clinicians could utilize this program in treating rape-related PTSD are discussed.  相似文献

Null hypothesis significance testing (NHST) is the most widely accepted and frequently used approach to statistical inference in quantitative communication research. NHST, however, is highly controversial, and several serious problems with the approach have been identified. This paper reviews NHST and the controversy surrounding it. Commonly recognized problems include a sensitivity to sample size, the null is usually literally false, unacceptable Type II error rates, and misunderstanding and abuse. Problems associated with the conditional nature of NHST and the failure to distinguish statistical hypotheses from substantive hypotheses are emphasized. Recommended solutions and alternatives are addressed in a companion article.  相似文献
