The aim of this work was to analyse the psychometric properties of the semantics and pragmatics modules of the Objective and Criterial Language Battery (BLOC). For the semantics module (n= 259), Cronbach's alpha was 0.84; for the pragmatics module (n= 142), Cronbach's alpha was 0.91. A Categoric Principal Components Analysis (CAPCAT), produced unidimentional solutions, explaining 41.65% of the variance in the semantics module, and 41.77% in the pragmatics module. We did not find differences in performance by sex. By socio-economic status, lower status children performed worse than those of middle and higher status, but only in the semantics module. Differences by age were small, with both modules producing between 3 and 4 homogeneous groups with substantial overlap. Lack of discrimination is probably related to reduced variability due to low performance in the Chilean samples. Compared to Spain, medians in the semantics module were lower than expected (though medians in the pragmatics module were slightly higher). 相似文献

In this study we analyze the attentional performance using different cognitive load attentional tasks: low-load cognition (0-CPT) and high-load cognition (DS-CPT). Participants were a group of schizophrenic patients and two groups of normal population psychometrically classified as low schizotypy and high schizotypy according to the SPQ. Our results show that schizophrenic patients were more sensitive to increments on cognitive load, being their attentional performace worse than the rest of the groups. The lack of significant findings in vigilance on the schizotypal traits group is discussed in terms of conceptual and methodological issues about the utility of psychometric strategies to identify vulnerable populations within the spectrum of the schizophrenic disorders. 相似文献

Importance-Performance Analysis (IPA) constitutes an indirect approximation to user's satisfaction measurement that allows to represent, in an easy and functional way, the main points and improvement areas of a specific product or service. Beginning from the importance and judgements concerning the performance that users grant to each prominent attributes of a service, it is possible to obtain a graphic divided into four quadrants in which recommendations for the organization economic resources management are included. Nevertheless, this tool has raised controversies since its origins, referred fundamentally to the placement of the axes that define the quadrants and the conception and measurement of the importance of attributes that compose the service. The primary goal of this article is to propose an alternative to the IPA representation that allows to overcome the limitations and contradictions derived from the original technique, without rejecting the classical graph. The analysis applies to data obtained in a survey about satisfaction with primary health care services of Galicia. Results will permit to advise to primary health care managers with a view toward the planning of future strategic actions. 相似文献

This paper explores the impact of the legitimacy of power position on powerholders' impressions, expectancies' confirmation processes, and decisions about subordinates in the context of a personnel selection process. Participants were assigned to a power position (they were told they will be representatives in a students conference and they will be able to select a mate to go also to the conference and to work under their supervision) on the basis of positive feedback regarding their supervisory skills (legitimate) or negative feedback regarding their supervisory skills (illegitimate). Two applicants were proposed as subordinates: one high in sociability and competence and the other low in both dimensions. Although participants in the two conditions noticed the superiority of one candidate over the other, illegitimate powerholders selected the least sociable and competent subordinate more often than legitimate powerholders. Illegitimate participants also request more information about the best than about the worse candidate. We interpret our findings in light of the larger literature suggesting an impact of illegitimacy on people's attempts to rationalize and justify their position as well as to perpetuate the existing social arrangement. 相似文献

In this paper we analyze differences between cognitive (selection, organizational, elaboration and rehearsal) and self-regulatory (planning, monitoring-regulating) strategies depending on academic goals. A total of 447 obligatory secondary education students (55% boys and 44,7% girls) participated in this study. The results indicated that as well as learning goals, other goals (obtain social approval or a good job) are related to the use of strategies and study engagement. Even performance-approach and performance-avoidance goals are significantly related to cognitive and self-regulatory strategies use. 相似文献

There is little doubt about the importance of validity during the compilation and evaluation of tests. Nevertheless, intense debate has arisen with regard to incorporating the consequences of test use as a further source of evidence in the most recent edition of the AERA, APA, NCME Standards . After reviewing the historical antecedents of the issue and the main lines of approach of both defenders and critics, this paper sets out the arguments which may be used in answer to the question: 'At what point should the analysis of the consequences of test use become part of validation?' The response of the AERA, APA, NCME Standards has clear similarities with the perspective adopted towards the consideration of bias in tests as a problem of validity. Finally, the paper describes how consequence validation may be subject to tension arising from the evolution of notions of justice in test use. 相似文献

Culicover and Jackendoff have recently described an approach to language representation where semantic structure works, alongside syntax, as a generative system with its own structure and principles of composition. Well-known neurological observations support this view. They show that in the presence of a syntactic impairment, comprehension can take place but only if the sentence's semantic structure is rich enough. This would suggest the existence of syntax-independent semantic combinatorial mechanisms, as Culicover and Jackendoff's model proposes. 相似文献

This paper presents the Nursing Motives for Helping Scale (N-MHS), an instrument designed for the evaluation of three of the four motives for helping derived from Batson's helping pathway theory. Dimensionality was analyzed by means of principal component analysis (n = 113), followed by confirmatory factor analysis. A 3-factor structure (corresponding to Batson's differentiation among altruistic motivation, reward-seeking motivation, and punishment-avoidance motivation, respectively), with 9 items distributed in three latent variables, revealed an acceptable fit to the data. Alpha values (.60 - .74) showed that internal consistency was acceptable for a newly developed subscale with a small number of items. Convergence validity was evaluated with correlations between N-MHS subscales scores and scores on the Professional Expectations Scale (Garrosa, Moreno-Jiménez, Rodríguez-Carvajal, and Morante, 2005). The three resulting subscales are a promising instrument for the evaluation of three nursing motives for helping that can contribute to reduce the potential risks and to improve the potential benefits both for the nurse and the patient. 相似文献

Traditional models of attitude change have assumed that when people appear to have changed their attitudes in response to new information, their old attitudes disappear and no longer have any impact. The present research suggests that when attitudes change, the old attitude can remain in memory and influence subsequent behavior. Four experiments are reported in which initial attitudes were created and then changed (or not) with new information. In each study, the authors demonstrate that when people undergo attitude change, their old and new attitudes can interact to produce evaluative responses consistent with a state of implicit ambivalence. In Study 1, individuals whose attitudes changed were more neutral on a measure of automatic evaluation. In Study 2, attitude change led people to show less confidence on an implicit but not an explicit measure. In Studies 3 and 4, people whose attitudes changed engaged in greater processing of attitude-relevant information than did individuals whose attitudes were not changed. 相似文献

The aim of the present paper was to examine the differences in game-related statistics between basketball players who are selected for the starting five of the team (starters) and those who are not (nonstarters) when related to game outcome (winning and losing) and team quality (best teams, teams classified for the playoffs; and worst teams, teams who miss playoff classification). Archival data were gathered for all 2002-2003 regular season games from the Portuguese Professional League (N = 156). Discriminant analysis was used to identify the game-related statistics that differentiate between starters and nonstarters and interpreted by the examination of the structure coefficients (SC). When the best teams won the games, results described differences between starters and nonstarters with an emphasis on defensive rebounds (SC = .32), assists (SC = .32) and committed fouls (SC = -.68). When the worst teams won the games, results described differences between starters and nonstarters with an emphasis on 2-point field goals successful (SC = .47) and unsuccessful (SC = .48), defensive rebounds (SC =.39), successful free throws (SC =.32), and committed fouls (SC = -.55). An also important finding was that, in best teams, the nonstarters' performance was worse in the games that the team lost, whereas in worst teams, it was the starters' performance that was worse in the games that the team lost. 相似文献
