Williams  John E.  Satterwhite  Robert C.  Best  Deborah L. 《Sex roles》1999,40(7-8):513-525
Williams and Best's (1982, 1990a) cross-culturalgender stereotype data from 25 countries, previouslyanalyzed in terms of affective meanings, ego states, andpsychological needs, were re-analyzed in terms of the Five Factor Model (FFM) of personality.In each country, participants were approximately 100university students, equally divided by gender. Withresults averaged across all countries, it was found that the pancultural male stereotype was higherthan the pancultural female stereotype on Extraversion,Conscientiousness, Emotional Stability, and Openness toExperience while the pancultural female stereotype was higher on Agreeableness. Re-analysis of thestereotype data from Japan and Pakistan, which had beenfound relatively atypical in previous analyses, revealedFFM profiles generally similar to the pancultural profiles. The evaluative nature of each factoris discussed and related to the stereotypes associalization models.  相似文献

Although there has been a proliferation of models of supervision in the marriage and family therapy literature recently, most tend to focus on methods rather than on the process of supervision. The model presented here is grounded in developmental concepts and focuses on student learning through a dialectical process of cognitive and emotional growth and incorporates three stages: 1) developing relationships; 2) breaking impasses, and 3) orchestrating changes. Students discover that supervision becomes isomorphic with relationship issues that arise in their therapy sessions. Dialectical in nature in that each stage is characterized by the resolution of contradictory emotions, the supervision process helps supervisees experience emotional shifts in their interactions with others, referred to as emotional restructuring.  相似文献

Zusammenfassung. Das hier vorgestellte Modell lernt graduell, Planungsaufgaben aus der Klasse der Maschinenbelegungsprobleme (job-shop-scheduling problems) zu lösen. Mit Hilfe des Chunking-Mechanismus von Soar wird episodisches Wissen über die Belegungsreihenfolge von Aufträgen auf Maschinen memoriert. Bei der Entwicklung des Modells wurden zahlreiche qualitative (z. B. Transfereffekte) und quantitative Befunde (z. B. Bearbeitungszeiten) aus einer früheren empirischen Untersuchung berücksichtigt. In einer Validierungsstudie wurden dieselben Aufgaben von 14 Probanden und dem Modell bearbeitet. Die Passung von Simulationsdaten und empirischen Ergebnissen fiel insgesamt gut aus. Allerdings löst das Modell die Aufgaben schneller und zeigt auch einen etwas besseren Lernverlauf als die Probanden. Das Modell liefert eine Erklärung für das Rauschen, das typischerweise bei Bearbeitungszeiten zu beobachten ist: es handelt sich um erworbenes Wissen, das mehr oder weniger gut und auch unterschiedlich häufig auf neue Situationen übertragen wird. Der Lernverlauf der Probanden entspricht nur für aggregierte Daten einer Potenzfunktion (power law). Der vorgestellte Mechanismus zeigt, wie ein symbolisches Modell der Informationsverarbeitung graduelle Verhaltensänderungen generiert und wie der offensichtliche Erwerb allgemeiner Prozeduren ohne explizites Lernen von deklarativen Regeln erfolgen kann. Es wird nahegelegt, daß es sich hier um die Modellierung einer Form impliziten Lernens handelt. Summary. The model presented here gradually learns how to perform a job-shop scheduling task. It uses Soar's chunking mechanism to acquire episodic memories about the order to schedule jobs. The model was based on many qualitative (e.g., transfer effects) and quantitative (e.g., solution time) regularities found in previously collected data. The model was tested with new data where scheduling tasks were given to the model and to 14 subjects. The model generally fit these data with the restrictions that the model performs the task (in simulated time) faster than the subjects, and its performance improves somewhat more quickly than the subjects' performance. The model provides an explanation of the noise typically found in problem solving times - it is the result of learning actual pieces of knowledge that transfer more or less to new situations but rarely by an average amount. Only when the data are averaged (i.e., over subjects) does the smooth power law appear. This mechanism demonstrates how symbolic models can exhibit a gradual change in behavior and how the apparent acquisition of general procedures can be performed without resorting to explicit declarative rule generation. We suggest that this may represent a type of implicit learning.  相似文献

Linguistics must again concentrate on the evolutionary nature of language, so that language models are more realistic with respect to human natural languages and have a greater explanatory force. Multi-agent systems are proposed as a possible route to develop such evolutionary models and an example is given of a concrete experiment in the origins and evolution of word-meaning based on a multi-agent approach.  相似文献

Nonverbal Counting in Humans: The Psychophysics of Number Representation   总被引:12,自引:0,他引:12  
In a nonverbal counting task derived from the animal literature, adult human subjects repeatedly attempted to produce target numbers of key presses at rates that made vocal or subvocal counting difficult or impossible. In a second task, they estimated the number of flashes in a rapid, randomly timed sequence. Congruent with the animal data, mean estimates in both tasks were proportional to target values, as was the variability in the estimates. Converging evidence makes it unlikely that subjects used verbal counting or time durations to perform these tasks. The results support the hypothesis that adult humans share with nonverbal animals a system for representing number by magnitudes that have scalar variability (a constant coefficient of variation). The mapping of numerical symbols to mental magnitudes provides a formal model of the underlying nonverbal meaning of the symbols (a model of numerical semantics).  相似文献

A selective review of some recent theoretical developments in the field of close relationships is presented. We describe demographic developments reflecting flux in relationships and the family and what may be viewed as a revolution in gender relations and the family over the past three to four decades. Also reviewed are theories on the development, maintenance, and ending of relationships, as well as the “dark side" of closerelationships. We conclude that the close-relationships field is likely to continue to develop and prosper as people search for answers to daunting relationship problems.  相似文献

Two secondary students with moderate disabilities (one per classroom) attended Advanced English classes with peers without disabilities in a rural high school. In additional to conducting planned daily instruction, each English teacher also systematically presented three sets of information (two facts per set) to each student with disabilities during the course of the class using a parallel treatments design. Each set of information included a fact related to the English class (e.g., Begin each sentence with a capital letter.) and a fact not related to the English class (e.g., The governor of Kentucky is Paul Patton.). The special education teacher conducted daily probe sessions to document acquisition. Of the six facts presented to each student with disabilities, one student acquired two related facts and one unrelated fact, while the other student acquired two related and two unrelated facts. This investigation implies that students who are fully included can acquire information presented by the regular classroom teacher during the course of a typical class and that teachers can facilitate learning by planning to present such information in a systematic fashion.  相似文献
