Infarct si?e (number of 1-mm2 pixels in the lesion) on CT scans of 30 aphasia patients was obtained with a semiautomated computer program. The mean number of lesion pixels present per slice containing lesion was approximately 500 for mild aphasias (transcortical motor and conduction), 700 for Wernicke's, 1000 for Broca's, 1500 for mixed, and 2000 for globals. These differences were significant for of the group pairwise comparisons. When lesion locus was controlled for in the anterior/posterior plane, 73–100% of the aphasia patients were correctly classified as to type of aphasia by a discriminant analysis utilizing only the number of lesion pixels present on two CT slices. Different slice combinations were used for different aphasia group comparisons. There was a significant correlation between severity of aphasia and lesion size. There was a significant correlation between lesion size and the CT numbers in the lesion. This type of analysis may be useful to predict the prognosis for recovery potential in aphasics who have CT scans performed at 2 months poststroke. 相似文献

中国古代关于认识真理性检验标准的思想可以大致归纳为四种主要观点。先秦及汉代的唯物主义思想家已经有了把感觉经验和行为效果作为检验认识真理性标准的思想;古代唯心主义思想家则坚持无客观标准论,他们要么直接坚持主观标准论,要么认为根本无是非标准可言;宋、明、清时期的一些唯物主义哲学家提出并坚持以客观事物或事实作为检验认识真理性的标准;与此不同,王廷相、王夫之、颜元等人则提出“行”标准说,这种颇具光辉的哲学思想,使中国古代关于认识真理性检验标准思想的探讨大大前进了一步。 相似文献

The present study examined the factor structure, internal consistency, and construct validity of the parent version of the Social Competence and Behavior Evaluation-30 for preschoolers (SCBE-30; LaFreniere, P. J. (1990). Social competence and behavior evaluation-30. Unpublished measure.), an adaptation of the validated teacher version of the same measure (LaFreniere & Dumas, Psychol. Asses. 8 (1996) 369). The parent version of the SCBE-30 is a 30-item Likert rating scale questionnaire designed to assess patterns of anxiety/withdrawal, anger/aggression, and social competence. Principal components analysis was used to identify the factor structure of the parent version of the SCBE-30 (N = 218 preschool children). To assess construct validity, a compliance task was utilized to determine whether children identified as high on anxiety/withdrawal, anger/aggression, or social competence with the parent version of the SCBE-30 (n = 20 for each group) could be distinguished behaviorally on several observational variables. Principal components analysis identified three factors accounting for 44% of the variance. Ten items positively loaded onto each factor and matched conceptual expectations. A between-subjects MANOVA demonstrated significant group differences in observed child behaviors including compliance, noncompliance, subtypes of noncompliance, and aversive behavior. Results of the current study suggested that the parent version of the SCBE-30 demonstrated both internal consistency and construct validity, and findings paralleled many of the results from LaFreniere and Dumas' validation of the teacher version of the SCBE-30. 相似文献

A review and critique of the literature pertaining to the use of cognitive remediation techniques in patients with schizophrenia is presented. The review is organized into three sections, according to the neuropsychological deficit targeted for remediation: 1) executive-function, 2) attention, and 3) memory. With regards to executive-function, despite an initial report suggesting that Wisconsin Card Sorting Test performance cannot be remediated, subsequent studies suggest that performance can be improved on a variety of dependent measures including perseverative errors, categories achieved, and conceptual level responses. These observations were confirmed by a meta-analytic investigation that revealed large mean effects sizes (d
+ = 0.96) for these studies. Effect sizes were homogenous across discrepant remediation strategies and dependent measures. With regards to attention, serial scanning can be improved with instruction and reinforcement, whereas there is mixed evidence suggesting that practice-based attention drills can improve performance on measures of sustained attention in schizophrenia. With regards to memory, relatively simple semantic and affective elaborate encoding strategies elevates verbal list-learning memory in patients with schizophrenia to levels consistent with controls. A similar encoding procedure, combined with vigilance training, produces substantial improvement in social cue recognition. Avenues for future research are discussed. 相似文献

This essay provides a critical history of the debate on the Rorschach Inkblot Tests administered to 22 leading figures of the Third Reich who were imprisoned in Nuremberg in 1945–1946. This debate occurred in two stages. The question at the heart of the first stage was whether the Nazi leaders were sane or psychopaths. Despite a strong disagreement concerning the use of these diagnostic labels, there was a surprisingly broad agreement on the actual substance of the discrepant diagnoses. Divisions of opinion, however, arose from political dissension in two areas: the nature of liberal democracies and authoritarian regimes, and the possibility of trust in any political leadership. The second stage was marked by an ideology of convergence aimed at establishing a consensual "scientific truth" on the Nazi Rorschachs. Thus, the politics of the second phase were motivated by interests and ambitions internal to the field of Rorschach expertise, rather than by extraneous political anxieties. 相似文献

In a longitudinal study using the Washington University Sentence Completion Test (WUSCT), we examined changes in ego development in response to the events of September 11, 2001. A sample of 24 individuals responded to the WUSCT in both the summer and fall of 2001, before and after the events of September 11. A significant decrease in mean ego level was found following September 11, as well as more equivocal support for an increase in variability in responses to the WUSCT. 相似文献

Hispanics have become the largest minority group in the United States. Hispanic children typically come from working class homes with parents who have limited English language skills and educational training. This presents challenges to psychologists who assess these children using traditional IQ tests because of the considerable verbal and academic (e.g., quantitative) content. Some researchers have suggested that intelligence conceptualized on the basis of psychological processes may have utility for assessment of children from culturally and linguistically diverse populations because verbal and quantitative skills are not included. This study examined Hispanic children's performance on the Cognitive Assessment System (CAS; [Naglieri, J.A., and Das, J.P. (1997). Cognitive Assessment System. Itasca, IL: Riverside.]) which is based on the Planning, Attention, Simultaneous, and Successive (PASS) theory of intelligence. The scores of Hispanic (N = 244) and White (N = 1956) children on the four PASS processes were obtained and the respective correlations between PASS and achievement compared. Three complementary sampling methodologies and data analysis strategies were chosen to compare the Ethnic groups. Sample size was maximized using nationally representative groups and demographic group differences were minimized using smaller matched samples. Small differences between Hispanic and non-Hispanic children were found when ability was measured with tests of basic PASS processes. In addition, the correlation between the PASS constructs and achievement were substantial for both Hispanic and non-Hispanic children and were not significantly different between the groups. 相似文献

According to Horwich’s use theory of meaning, the meaning of a word W is engendered by the underived acceptance of certain sentences containing W. Horwich applies this theory to provide an account of semantic stipulation: Semantic stipulation proceeds by deciding to
accept sentences containing an as yet meaningless word W. Thereby one brings it about that W gets an underived acceptance property. Since a word’s meaning is constituted by its (basic) underived acceptance property,
this decision endows the word with a meaning. The use-theoretic account of semantic stipulation contrasts with the standard
view that semantic stipulation proceeds by assigning the meaning (reference) to W that makes a certain set of sentences express true propositions. In this paper I will argue that the use-theoretic account
does not work. I take Frege to have already made the crucial point: "a definition does not assert anything but lays down something
["etwas festsetzt"]” (Frege 1899, 36). A semantic stipulation for W cannot be the decision to accept a sentence containing W or be explained in terms of such an acceptance. Semantic stipulation constitutes a problem for Horwich's use theory of meaning,
especially his basic notion of acceptance.

ABSTRACT— Mental process and mental experience are not the same thing. The former is the operation of the mind; the latter is the subjective life that emerges from that operation. In social evaluation, implicit and explicit attitudes express this distinction. Although it is clear that they are not the same, how they differ is not. Across content domains, implicit and explicit attitude measures show substantial variability in the strength of correspondence, ranging from near zero to strongly positive. Variation in controllability, intentionality, awareness, or efficiency is thought to differentiate implicit and explicit attitudes. Dual-process theories and empirical evidence for moderating influences of implicit–explicit attitude relations provide a framework for comprehending relations between the operation and the experience of the mind. 相似文献

Cross-Validation of the Behavioral and Emotional Rating Scale-2 Youth Version: An Exploration of Strength-Based Latent Traits 总被引:1,自引:0,他引:1

High-quality measurement is a necessary requirement to develop and evaluate the effectiveness of programs that use strength-based
principles and strategies. Using independent cross-validation samples, we report two studies that explored the construct validity
of the BERS-2 Youth Report, a popular measure designed to assess youth strengths, whose conceptual structure has not yet been
examined. In Study 1, an exploratory factor analysis found a four-factor solution with conceptual support, which included
both internal assets associated with (a) the management of emotions and positive social interaction skills and (b) engagement
in the important social contexts of family and school. In Study 2, confirmatory factor analyses found reasonable model fit
for the BERS-2 five-factor structure and superior model fit for the more parsimonious four-factor solution found in Study
1. In future studies, parallel reporting of the four-factor model may provide additional insight to the nature and structure
of the BERS-2 Youth Version’s clinical validity and utility when compared with the five-factor model, thus potentially contributing
to a broader objective to develop a better understanding of important strength-based latent traits. 相似文献
