Two studies using novel extensions of the conditioned head-turning method examined contributions of rhythmic and distributional properties of syllable strings to 8-month-old infants' speech segmentation. The two techniques introduced exploit fundamental, but complementary, properties of representational units. The first involved assessment of discriminative response maintenance when simple training stimuli were embedded in more complex speech contexts; the second involved measurement of infants' latencies in detecting extraneous signals superimposed on speech stimuli. A complex pattern of results is predicted if infants succeed in grouping syllables into higher-order units. Across the two studies, the predicted pattern of results emerged, indicating that rhythmic properties of speech play an important role in guiding infants toward potential linguistically relevant units and simultaneously demonstrating that the techniques proposed here provide valid, converging measures of infants' auditory representational units.  相似文献

Individuals with social anxiety disorder (SAD) have difficulties in their romantic relationships, including decreased satisfaction and intimacy, but the reasons for these difficulties are poorly understood. Because fear of negative evaluation is a cardinal feature of SAD, perceived criticism from a romantic partner may play a central role in socially anxious individuals’ relationships. In the present study, we compared levels of perceived, expressed, and observed criticism and reactions to criticism among individuals with SAD and their partners (n = 21), individuals with other anxiety disorders and their partners (n = 35), and couples free of psychopathology (n = 30). Participants rated both global criticism and criticism during a 10-minute problem-solving task, which was also coded for criticism by observers. Individuals with anxiety disorders showed elevated levels of interaction-specific perceived criticism, expressed criticism, and upset and stress due to criticism relative to normal controls; they also reported that the interaction was more stressful. However, there were no group differences on global measures of criticism, and the two anxious groups did not differ on any measures. Findings suggest that the high levels of criticism anxious individuals perceive and their corresponding negative reactions to criticism, though not specific to SAD, may account for some of the relationship difficulties that have been identified in SAD. Results also indicate that anxious individuals may contribute to their relationship difficulties by being highly critical themselves. Overall, our findings point to the need for a clinical focus on decreasing perceived criticism among individuals with anxiety disorders.  相似文献

This article reviews The Perks of Being a Wallflower (Halfon, Smith, Malkovich, & Chbosky, 2012), a coming-of-age film about 3 high school students attempting to survive school, find themselves, and connect with others. The authors provide a synopsis of various portions of the film and identify important aspects of relational-cultural theory (RCT) within its plot, such as growth-fostering relationships, controlling images, and relational images. Various characters’ plotlines are discussed in relation to what RCT identifies as paramount tenets of human development and mental health. The authors also briefly discuss other counseling issues touched on within the film (i.e., affectional identity, sexual assault, and relational violence).  相似文献

The current paradigm in medicine generally distinguishes between genetic and environmental causes of disease. Although the word paradigm has become a commonplace, the theories of Thomas Kuhn have not received much attention in the journals of medicine. Kuhn's structuralist method differs radically from the daily activities of the scientific method itself. Using linguistic theory, this essay offers a structuralist reading of Thomas Kuhn's The Structure of Scientific Revolutions. Our purpose is to highlight the similarities between these structuralist models of science and language. In part, we focus on the logic that enables Kuhn to assert the priority of perception over interpretation in the history of science. To illustrate some of these issues, we refer to the distinction between environmental and genetic causes of disease. While the activity of scientific research results in the revision of concepts in science, the production of significant differences that shape our knowledge is in part a social and linguistic process.  相似文献

Current models of face representation involve the notion of a high-dimensional face space. Computational models of face space based on principal components analysis (PCA) have been successfully used to predict human judgements of face sex or race. In this work the capability of PCA-based face spaces to predict human judgements of face similarity is examined. Three different paradigms were used. In Experiment 1 subjects learned face-name associations for 18 faces and identified these faces on tachistoscopic presentation. The number of confusions was used as a measure of face similarity. In Experiment 2 the same subjects subjectively rated the similarity of all 153 possible face pairs. In Experiment 3 reaction time to identify a face in an odd-man-out task was measured as an index of face similarity. These empirical measures were correlated with distance of the faces in PCA-based spaces of different dimensionalities. For Experiments 1 and 2 these correlations were highest for one-or two-dimensional face spaces (r=−0.27 vs. −0.28). For Experiment 3 the correlation was highest for a space consisting of 13 dimensions (r=−0.51). Thus PCA-based spaces seem capable to predict human similarity judgements to some extent. Possible reasons for the differences in predictability between paradigms are discussed.  相似文献

This exploratory study uses qualitative methods to focus on the largely unexamined role of the grandfather and to examine men's experiences as grandfathers. We gathered information through both surveys and individual interviews to explore men's feelings and attitudes toward the grandfather role. Of the 51 grandfathers that completed a survey, 20 participated in interviews. Our examination of the data collected reveals the life lessons men teach their grandchildren. The grandfathers in this study expressed strong desires for purposeful involvement in their grandchildren's lives and indicated desires for transferring values to grandchildren and teaching interpersonal relationships. Through this involvement, they educate through life experiences and serve as mentors for their grandchildren. We suggest that this mentoring role makes a positive contribution to the lives of grandchildren and to the identity of grandfathers.  相似文献

Our understanding of sexual prejudice, or prejudice against gay men, lesbian women, bisexual people, and other sexual minorities, has improved substantially over the last few decades. Less is known about the factors that predict trans prejudice, or prejudice against trans people. Using the framework of social identity theory, we examined the relationship between gender self-esteem, sexual prejudice toward gay men and lesbian women, and trans prejudice in a sample of 391 self-identified cisgender heterosexual students from a Midwestern university in the United States. Compared to women, men reported more sexual prejudice, trans prejudice, more prejudice toward gay men than lesbian women, and more violence toward, teasing of, and discomfort around trans women than trans men. Whereas both men and women reported more teasing of trans women than of trans men, men reported more discomfort around trans women and women reported more discomfort around trans men. Gender self-esteem significantly predicted sexual prejudice and trans prejudice in men but not women. Consistent with other research, our results indicate that men's sexual prejudice and trans prejudice may be motivated by similar factors, whereas the predictors of women's prejudice may be more specific to the type of prejudice.  相似文献

拟人化是将人类特征、动机、意向或心理状态赋予非人对象的心理过程或者个体差异。拟人化的产生受到激发主体知识、效能动机和社会动机的影响,现有研究包括对自然、超自然、动物、机器、品牌和产品等的拟人化。对自然的拟人化能够促进环境保护行为,对动物、机器、品牌和产品的拟人化则形式多样、后果复杂。未来研究的焦点可能在人-机器人交互以及拟人化与可爱的关系问题上。  相似文献

It has recently become popular to suggest that cognition can be explained as a process of Bayesian prediction error minimization. Some advocates of this view propose that attention should be understood as the optimization of expected precisions in the prediction-error signal (Clark, 2013, 2016; Feldman & Friston, 2010; Hohwy, 2012, 2013). This proposal successfully accounts for several attention-related phenomena. We claim that it cannot account for all of them, since there are certain forms of voluntary attention that it cannot accommodate. We therefore suggest that, although the theory of Bayesian prediction error minimization introduces some powerful tools for the explanation of mental phenomena, its advocates have been wrong to claim that Bayesian prediction error minimization is ‘all the brain ever does’.  相似文献
