This study explored the perspectives of husbands regarding the participation of their wives in professional occupations. The participants included nine South African Indian men in dual-career marriages (ages ranging from 25 to 54 years old). The completed semi-structured, life-story interviews focused on the socio-historic and contemporary influences on marital and familial dynamics with working spouses. Thematic analysis of the data revealed the husbands to be supportive of their spouses across familial and occupational roles. The findings contradict the stereotype that South African Indian husbands are unsupportive of their working spouses. 相似文献

Propositional attitude verbs, such as think and want, have long held interest for both theoretical linguists and language acquisitionists because their syntactic, semantic, and pragmatic properties display complex interactions that have proven difficult to fully capture from either perspective. This paper explores the granularity with which these verbs’ semantic and pragmatic properties are recoverable from their syntactic distributions, using three behavioral experiments aimed at explicitly quantifying the relationship between these two sets of properties. Experiment 1 gathers a measure of 30 propositional attitude verbs’ syntactic distributions using an acceptability judgment task. Experiments 2a and 2b gather measures of semantic similarity between those same verbs using a generalized semantic discrimination (triad or “odd man out”) task and an ordinal (Likert) scale task, respectively. Two kinds of analyses are conducted on the data from these experiments. The first compares both the acceptability judgments and the semantic similarity judgments to previous classifications derived from the syntax and semantics literature. The second kind compares the acceptability judgments to the semantic similarity judgments directly. Through these comparisons, we show that there is quite fine‐grained information about propositional attitude verbs’ semantics carried in their syntactic distributions—whether one considers the sorts of discrete qualitative classifications that linguists traditionally work with or the sorts of continuous quantitative classifications that can be derived experimentally. 相似文献

We investigate the hypothesis that our conceptual systems provide two formally distinct ways of representing categories by investigating the manner in which lexical nominals (e.g., tree, picnic table) and phrasal nominals (e.g., black bird, birds that like rice) are interpreted. Four experiments found that lexical nominals may be mapped onto kind representations, whereas phrasal nominals map onto class representations but not kind representations. Experiment 1 found that phrasal nominals, unlike lexical nominals, are mapped onto categories whose members need not be of a single kind. Experiments 2 and 3 found that categories named by lexical nominals enter into both class inclusion and kind hierarchies and thus support both class inclusion (is a) and kind specification (kind of) relations, whereas phrasal nominals map onto class representations which support only class inclusion relations. Experiment 4 showed that the two types of nominals represent hierarchical relations in different ways. Phrasal nominals (e.g., white bear) are mapped onto classes that have criteria of membership in addition to those specified by the class picked out by the head noun of the phrase (e.g., bear). In contrast, lexical nominals (e.g., polar bear) specify one way to meet the criteria specified by the more general kind concept (e.g., bear). Implications for the language-conceptual system interface, representation of hierarchical relations, lexicalization, and theories of conceptual combination are discussed. 相似文献

ResumenEste artículo presenta el desarrollo de un sistema de instrucción asistida por ordenador (IAO), el sistema Abraxas, dirigido a los estudiantes de Psicología. Su objetivo es enseñar la metodología del análisis factorial, tema de considerable dificultad para una gran mayoría de los estudiantes. Desde hace unos años, los sistemas IAO se han convertido en herramientas cotidianas de trabajo en distintos ámbitos de investigación y aplicación. Sin embargo, dichos sistemas no cumplen su objetivo en la gran mayoría de los casos, siendo una de las causas que durante el proceso de diseño y desarrollo, no se toman en cuanta una serie de pautas que se deben seguir al diseñar y desarrollar sistemas IAO, de modo que se optimice el aprendizaje real de los usuarios. Abraxas se divide en 5 módulos instruccionales: introducción temática, idea de correlación, idea de factor, desarrollo matemático y modelos factoriales. En cada módulo se usan distintos tipos de pantallas, de enseñanza, criterialesy de evaluación, y cada uno de estos módulos se ha valorado con potenciales usuarios desde el momento de su diseño; los resultados han indicado el éxito de esta estrategia. 相似文献

人工感知技术突破人类自然感官的限制,在拓展人类对世界和自我认知的同时带来了新的医学伦理挑战,“侵入性”概念在医疗器械开发、监管、市场准入和使用中起着重要作用,但传统的侵入性和非侵入性概念已经不再适用于新兴医疗神经技术的伦理讨论。人工感知技术的发展不仅关乎科学技术和实际应用,还涉及人类的价值观、医学伦理和人类自身文明的未来发展方向。在当前认知方式的变革和转型中,因为人工感知的临床应用对人体的特殊介入方式,思考人工感知技术带来的医学伦理新问题,重新反思医学技术与人类的关系,成为医学哲学当务之急。

Speech production is inextricably linked to speech perception, yet they are usually investigated in isolation. In this study, we employed a verbal-repetition task to identify the neural substrates of speech processing with two ends active simultaneously using functional MRI. Subjects verbally repeated auditory stimuli containing an ambiguous vowel sound that could be perceived as either a word or a pseudoword depending on the interpretation of the vowel. We found verbal repetition commonly activated the audition-articulation interface bilaterally at Sylvian fissures and superior temporal sulci. Contrasting word-versus-pseudoword trials revealed neural activities unique to word repetition in the left posterior middle temporal areas and activities unique to pseudoword repetition in the left inferior frontal gyrus. These findings imply that the tasks are carried out using different speech codes: an articulation-based code of pseudowords and an acoustic-phonetic code of words. It also supports the dual-stream model and imitative learning of vocabulary. 相似文献

Many studies are concerned with the bivariate relationships between Openness, fluid intelligence (Gf), and crystallized intelligence (Gc). Results suggest an influence of Gf and Openness on Gc. However, the overlap between Gf and Openness is rarely controlled for. Moreover, interaction effects or longitudinal influences are also often neglected. The present two studies aimed to elucidate exactly these interactions and longitudinal influences. Besides a main effect of Gf on Gc, Study 1 (N = 180) revealed an interaction effect between Openness and Gf. Study 2 utilized longitudinal data (N = 172) and identified an effect of Openness on the development of Gf. Gf and Openness predicted Gc 6 years later. A model integrating the results and providing a theoretical framework and outlook is proposed. 相似文献

Measuring the positive side of the work-family interface: Development and validation of a work-family enrichment scale 总被引:3,自引:0,他引:3
Based on current conceptualizations of enrichment, or the positive side of the work-family interface, a multi-dimensional measure of work-family enrichment is developed and validated using five samples. The final 18 item measure consists of three dimensions from the work to family direction (development, affect, and capital) and three dimensions from the family to work direction (development, affect, and efficiency). The validity of the scale was established by assessing the content adequacy, dimensionality, reliability, factor structure invariance, convergent validity, divergent validity, and its relationship to work and family correlates. 相似文献

The phenomenological philosopher Martin Heidegger's proposed transition from readiness-to-hand to presence-at-hand and the hypothesis of extended cognition were addressed empirically in an experiment on tool use. It involved a video game of steering erratically moving objects to a target while performing a secondary cognitive task. A strong perturbation of the hand-pointer linkage in the video game induced the transition from ready-to-hand to present-at-hand. In Experiment 1, this perturbation resulted in decreased motor performance and improved recall of task-irrelevant features. Experiment 2 replicated these results and addressed additional questions. Measures of movement variability based on the multifractal formalism confirmed the hypothesized decrease in functional integration of the tool during the perturbation. Dynamical interactions allow user and tool to act as a system. The tool is properly described as ready-to-hand during normal operation but as present-at-hand during perturbation. Physiological measures showed that the ready-to-hand to present-at-hand transition does not necessarily lead to a stress response. 相似文献
