Following the publication of the third edition Wechsler scales (i.e., WAIS-III and WMS-III), demographically corrected norms were made available in the form of a computerized scoring program (i.e., WAIS-III/WMS-III/WIAT-II Scoring Assistant). These norms correct for age, gender, ethnicity, and education. Since then, four new indexes have been developed: the WAIS-III General Ability Index, the WMS-III Delayed Memory Index, and the two alternate Immediate and Delayed Memory Indexes. The purpose of this study was to develop demographically corrected norms for the four new indexes using the standardization sample and education oversample from the WAIS-III and WMS-III. These norms were developed using the same methodology as the demographically corrected norms made available in the WAIS-III/WMS-III/WIAT-II Scoring Assistant. 相似文献

Archival data (N = 1,048 women, 1,136 men) from a mental health survey of college students were used to investigate incidence of nonsuicidal self-injury (NSSI), including cutting. Significant levels (defined as 4-5 lifetime incidents) were found in 9.3% of women and 5.3% of men. The Counseling Center Assessment for Psychological Symptoms (a global symptom inventory) and an assessment of trauma had been field tested with this sample. We randomly partitioned half of these data into a holdout sample and used the remainder to develop an NSSI screening inventory that included (a) 5 women's screening items, including 1 item to assess trauma experienced; (b) 11 men's screening items; and (c) 12 items common to men and women, including depression, dissociation, anger, unwanted thoughts, nightmares or flashbacks, and having witnessed trauma. Logistic regression and receiver-operating characteristic curve analysis suggested the inventory significantly discriminated NSSI men and women in the holdout sample, p < .001. Cutoff scores were identified to correctly classify about 48% of the true positive male and female NSSI cases, with false positive rates of 13.2% and 8.4% for women and men, respectively. 相似文献

The trade-off between exploration and exploitation is common to a wide variety of problems involving search in space and mind. The prevalence of this trade-off and its neurological underpinnings led us to propose domain-general cognitive search processes (Hills, Todd, & Goldstone, 2008). We propose further that these are consistent with the idea of a central executive search process that combines goal-handling across subgoal hierarchies. In the present study, we investigate 3 aspects of this proposal. First, the existence of a unitary central executive search process should allow priming from 1 search task to another and at multiple hierarchical levels. We confirm this by showing cross-domain priming from a spatial search task to 2 different cognitive levels within a lexical search task. Second, given the neural basis of the proposed generalized cognitive search process and the evidence that the central executive is primarily engaged during complex tasks, we hypothesize that priming should require search in the sense of a self-regulated making and testing of sequential predictions about the world. This was confirmed by showing that when participants were allowed to collect spatial resources without searching for them, no priming occurred. Finally, we provide a mechanism for the underlying search process and investigate 3 alternative hypotheses for subgoal hierarchies using the central executive as a search process model (CESP). CESP envisions the central executive as having both emergent and unitary processes, with one of its roles being a generalized cognitive search process that navigates goal hierarchies by mediating persistence on and switching between subgoals. 相似文献

This study examined how four domain-specific skills (arithmetic procedural skills, number fact retrieval, place value concept, and number sense) and two domain-general processing skills (working memory and processing speed) may account for Chinese children’s mathematics learning difficulties. Children with mathematics difficulties (MD) of two age groups (7-8 and 9-11 years) were compared with age-matched typically achieving children. For both age groups, children with MD performed significantly worse than their age-matched controls on all of the domain-specific and domain-general measures. Further analyses revealed that the MD children with literacy difficulties (MD/RD group) performed the worst on all of the measures, whereas the MD-only group was significantly outperformed by the controls on the four domain-specific measures and verbal working memory. Stepwise discriminant analyses showed that both number fact retrieval and place value concept were significant factors differentiating the MD and non-MD children. To conclude, deficits in domain-specific skills, especially those of number fact retrieval and place value understanding, characterize the profile of Chinese children with MD. 相似文献

One version of Moore’s Paradox is the challenge to account for the absurdity of beliefs purportedly expressed by someone who
asserts sentences of the form ‘p & I do not believe that p’ (‘Moorean sentences’). The absurdity of these beliefs is philosophically puzzling, given that Moorean sentences (i) are
contingent and often true; and (ii) express contents that are unproblematic when presented in the third-person. In this paper
I critically examine the most popular proposed solution to these two puzzles, according to which Moorean beliefs are absurd
because Moorean sentences are instances of pragmatic paradox; that is to say, the propositions they express are necessarily false-when-believed. My conclusion is that while a Moorean
belief is a pragmatic paradox, it is not
just another pragmatic paradox, because this diagnosis does not explain all the puzzling features of Moorean beliefs. In particularly,
while this analysis is plausible in relation to the puzzle posed by characteristic (i) of Moorean sentences, I argue that
it fails to account for (ii). I do so in the course of an attempt to formulate the definition of a pragmatic paradox in more
precise formal terms, in order to see whether the definition is satisfied by Moorean sentences, but not by their third-person
transpositions. For only an account which can do so could address (ii) adequately. After rejecting a number of attempted formalizations,
I arrive at a definition which delivers the right results. The problem with this definition, however, is that it has to be
couched in first-person terms, making an essential use of ‘I’. Thus the problem of accounting for first-/third-person asymmetry
recurs at a higher order, which shows that the Pragmatic Paradox Resolution fails to identify the source of such asymmetry
highlighted by Moore’s Paradox. 相似文献

Four experiments were conducted to provide further support for a dual-process approach to conjunction errors in recognition memory over a single-process approach. In Experiments 1, 2a, and 2b study words were repeated once (2 presentations) or several times (8 or 16 presentations), and a response signal delay (RSD) was manipulated (short vs long). Short RSD groups produced lower hit rates but higher conjunction error rates compared to long RSD groups. Repetition effects on conjunction errors occurred for short RSD but not long RSD groups. In Experiment 3, additional judgements on new items were solicited to show that the “null” effects for long RSD groups in the earlier experiments were, in fact, illusory. Together, the experiments provide evidence for recollection-based rejections of conjunction lures and support a dual-process theory of recognition memory over a single-process model. 相似文献

In creativity, there is scant evidence of significant racial and gender differences, and when such differences are found, there is no consistency regarding which groups perform best. There has been little work focusing on racial and gender biases and/or stereotypes within creativity assessment. It is study these issues by using a modified version of the Consensual Assessment Technique in which the judges are provided with information about the creators' gender and/or race. A total of 455 undergraduates assigned ratings for creativity, writing ability, and enjoyment to 60 poems downloaded from a poetry Web site. These poems either had no attribution or had (fictional) stereotypical Black, White, and Crossover names for each gender. Results suggest that novice raters using CAT methodology display little evidence of bias in their ratings of creativity, writing ability, and poem enjoyment. Very slight preference was found for poems assigned names of White females. 相似文献

Using a sample of 201 participants and a between‐subjects design, the perceived professionalism—suitability, capability, ease to talk to and friendliness—of male and female dentists and lawyers in various attires was examined. Results showed an absolute preference for male dentists and lawyers in professional and formal attire, respectively. Male dentists and lawyers in professional and formal attire were further rated as more suitable, capable, easier to talk to, and friendlier than female professionals, and than those dressed in smart or casual attire. Results are discussed in terms of positive dental outcomes and legal representation. Limitations are considered. 相似文献

As the workforce ages it becomes important to examine if there is misperception of creativity and age in work contexts. A laboratory experiment examined perceptions of the creativity of a team with both young and old workers and of a team composed entirely of young workers. Scripted videos portrayed such teams engaged in designing an outdoor advertising campaign. Altogether, 220 participants were randomly assigned to watch one of the video clips and complete a structured questionnaire. No significant differences were observed in the perceptions of the two teams' performance or of the quality of the resulting advertising proposal. In general, there was also no significant difference in the individual characteristics attributed to the four characters on the teams. However, participants aged 35 or above evaluated both teams and all four characters more favorably than participants aged 20–34. 相似文献
