Neural Network models are commonly used for cluster analysis in engineering, computational neuroscience, and the biological sciences, although they are rarely used in the social sciences. In this study we compare the classification capabilities of the 1-dimensional Kohonen neural network with two partitioning (Hartigan and Späthk-means) and three hierarchical (Ward's, complete linkage, and average linkage) cluster methods in 2,580 data sets with known cluster structure. Overall, the performance of the Kohonen networks was similar to, or better than, the performance of the other methods. 相似文献

Repetition priming is defined as a gain in item recognition after previous exposure. Repetition priming of face recognition has been shown to last for several months, despite contamination by everyday exposure to both experimental and control faces in the interval. Here we show that gains in face recognition in the laboratory are found from faces initially seen in a rather different context— on subject recruitment posters, even when the advertisements make no specific mention of experiments involving face recognition. The priming was greatest when identical pictures were shown in the posters and in the test phase, although different views of faces did give significant priming in one study. Follow-up studies revealed poor explicit memory for the faces shown on the posters. The results of these experiments are used to develop a model in which repetition priming reflects the process of updating representations of familiar faces. 相似文献

Cross-cultural commonality and variation in folk theories of knowing were studied by examining the organization of verbs of knowing in German and Japanese adults. German and Japanese adults performed one of two tasks: a similarity judgment task and an attribute rating task. Organizational structure was assessed for the similarity judgment task using multidimensional scaling and additive similarity tree analyses. The attribute rating task was used to describe the characteristics that organized the dimensions and clusters emerging from the scaling solutions. The folk theory of mind displayed was an information processing model with constructive components, although the constructive aspects were more salient for the Germans than for the Japanese. 相似文献

A population-based randomized intervention trial for the prevention of conduct problems (i.e., oppositional defiant disorder and conduct disorder) is described. The LIFT (Linking the Interests of Families and Teachers) intervention was designed for all first- and fifth-grade elementary school boys and girls and their families living in at-risk neighborhoods characterized by high rates of juvenile delinquency. The 10-week intervention strategy was carefully targeted at proximal and malleable antecedents in three social domains that were identified by a developmental model of conduct problems. From 12 elementary schools, 671 first and fifth graders and their families participated either in the theory-based universal preventive intervention or in a control condition. The intervention consisted of parent training, a classroom-based social skills program, a playground behavioral program, and systematic communication between teachers and parents. A multiple measure assessment strategy was used to evaluate participant satisfaction and participation, fidelity of implementation, and the immediate impacts of the program on targeted antecedents. 相似文献

We describe a set of algorithms that enhance the sensitivity of cancellation tests used in assessing visuospatial neglect. The algorithms can be readily implemented on a computer and can provide temporal and nontemporal data on strategies used during cancellation. We also present preliminary results from a group of 68 right-hemisphere brain-damaged patients and 12 age-matched control participants, which demonstrate the clinical significance of the measures we have defined. 相似文献

In this article, the authors describe the existential situation of the fast-track suburban couple and a treatment approach
based upon the philosophical concepts of Gabriel Marcel and Viktor Frankl. In this treatment approach, the therapist uses
availability, primary reflection and secondary reflection treatment experiences to host the client couple's discovery and
actualization of the meaning potential in their intimate life. 相似文献

The present study investigated the role of social support provisions and efficacy cognitions in adherence to a prescribed exercise regimen. A generalized estimating equations approach was employed to estimate regression coefficients via an iterative weighted least squares algorithm. Findings indicated that when employed as time-varying covariates, the social provisions of reassurance of worth, attachment, and, to a lesser extent, guidance were significantly associated with intraindividual fluctuations in program adherence. Specifically, individuals with a greater sense of self-worth were more likely to adhere throughout the program, whereas the effects of subject's perceptions of greater attachment, although generally related to sustained adherence, fluctuated over time. Findings also suggest that individuals perceiving higher levels of guidance were less likely to adhere during the early and concluding stages of the exercise program. Although synchronous covariation existed between efficacy cognitions and attendance, self-efficacy was not predictive of intraindividual change in attendance over time. Results are discussed in regard to the importance of self-referent processes and social provisions in exercise adherence, and the utility of the proposed generalized estimating equations approach to the analysis of longitudinal data. 相似文献

Recently, scholars have criticized what they call the “Kantian-Republican” thesis of freedom as non-domination. The main complaint is that domination is unavoidable. This concern can be separated into the problem of state domination, which suggests that the state's intervening powers necessarily dominate its citizens, and the problem of majority domination, which suggests that the People necessarily dominate individual citizen as a result of the potential to form dominating majorities. 相似文献

On a sunny Sunday afternoon in 2012 a conflict arose between two men riding a popular mountain biking track in New Zealand. The bulk of this was filmed from a helmet-mounted action camera, facilitating a single case analysis of the transition from an everyday trouble to an unexpected violent ending. The two riders come across each other travelling downhill at speed on a narrow track. Unease quickly develops for the camera-clad rider wants to pass the rider in front, but except for an intriguing and brief interlude, the first rider will not let the other pass. The second rider grows frustrated, progressing to tailgate the ‘slower’ rider, in the midst of which he invokes a rule of mountain biking conduct. The reflexive implications of the rule-invocation need to be seen to be believed. The video is used as data to get close to such seeing, and despite some limitations, we can see a clear trajectory where the rule significantly contributes to a moment of phenomenological salience. Thereafter, it becomes witnessably relevant to the conflict that develops. 相似文献
