When observers are asked to report a feature of a single target displayed in rapid serial visual presentation, they frequently make errors. Most frequently, a feature from the to-be-reported dimension pertaining to a stimulus presented near the target is reported. These migrations are so-called illusory conjunctions in the time domain. From parallel models, it is proposed that during the presentation of the series, the response features of the stimuli are extracted. If a high rate of presentation does not enable proper binding processes, the system could base its response on sophisticated guessing on the basis of the relative levels of activation of the available response features. However, the multiple extractions assumption has not received direct empirical support. We report two experiments in which the observers had to report their first and second response candidates. This double response paradigm makes it possible to test the assumption that more than one response feature is available for making a response. Furthermore, the application of the constant ratio rule (following Botella, Barriopedro, & Suero's, 2001, model) to the first responses allows predictions for the ratios between choices of the items for the second responses. The correlations between the observed and the predicted response proportions were .887 and .956 in the two experiments. This high predictive capacity indicates, first, that the observers have more than one response available, among which to choose, and second, that the choice among responses is determined largely in the same way for both, first and second responses. Nevertheless, the small errors in prediction are further reduced if a proportion of pure guesses is assumed in the second responses. These are probably due to memory losses, misidentifications of the features, and other factors impairing performance in second responses in comparison with first responses. 相似文献

This study examined the effects of counselor language switching and counselor ethnicity on bilingual Mexican American participants' emotional self‐disclosure. Counselor language (English only and Spanish with English) was crossed with counselor ethnicity (Mexican American and European American) to produce 4 treatment conditions. Judges' observations revealed that the European American counselor who language switched elicited the most emotional expression from participants. Este estudio examinó los efectos que un cambio de idioma por parte del consejero y la etnicidad del consejero tienen sobre la auto‐revelación emocional de los participantes México Americanos bilingües. El idioma del consejero (sólo inglés, y español con inglés) se combinó con su etnicidad (México Americano y Euro Americano) para generar 4 condiciones de tratamiento. Las observaciones de los jueces revelaron que el consejero Euro Americano que cambió de idioma obtuvo el mayor número de expresiones emocionales de los participantes. 相似文献

This teaching case illustrates the innovative application of an instructional technology modality, the WebQuest, in family
therapy training. It describes what a WebQuest involves, and how it can be used as a tool for developing critical thinking
and application of contemporary marriage and family therapy (MFT) theory to social and global issues. The authors discuss
the results of the survey and focus groups conducted to assess the value of this assignment from the students’ perspectives.
Results indicate that its application in a family therapy theories course fostered students’ awareness of global issues impacting
family life, integration of family therapy theories to serve children and families, creativity in developing their own intervention
models, and ability to discuss and integrate knowledge from different knowledge bases and perspectives. 相似文献

French readers' eye movements were monitored as they read a passage of text. Initial global analyses of word frequency, accounting for the majority of fixations in the text, revealed a good fit between the observed data and the simulated data from the E-Z Reader 7 model of eye movement control. However, the model did not perform as well on simulations of contextual predictability effects. A subset of 20 controlled words from the passage were used to examine the combined effects of frequency and predictability. Results from the observed data showed main effects of frequency and predictability but no interaction. With certain modifications, the E-Z Reader 7 model was able to adequately simulate the pattern of data. Although the E-Z Reader model successfully accounted for the present data, we believe that further modifications will be necessary in order to better account for data in the literature. 相似文献

Predictions derived from models of cultural pluralism and cultural assimilation were tested. Previous research has shown that highlighting differences between ethnic groups, in conjunction with self-focus, can reduce prejudice. The presented research tested the following questions: (a) does highlighting differences function to reduce prejudice between groups that are dissimilar to each other as well as between those that are highly similar, (b) is prejudice reduction due to distinctiveness a function of the lessened ingroup positivity or lessened outgroup negativity, (c) does making distinctiveness salient reduce prejudice toward only the distinctive outgroups or to outgroups more generically, and (d) does the manipulation equally impact African American, Mexican American, Mexican National, and White American participants? Results demonstrated that highlighting differences while simultaneously focusing on the self reduces prejudice, although similarity mediates the relationship with those who are perceived as more different. Distinctiveness also reduced outgroup negativity and generalized to other outgroups. Finally, the manipulation reduced prejudice only for White Americans, Mexican Americans, and Mexican Nationals. 相似文献

The objective of the current study was to compare the performance of schizophrenic patients and normal controls on implicit memory tests. Two neuropsychological tasks were administered to 29 patients and normal participant samples. The implicit tests were: Word fragment completion and Word production from semantic categories. The priming score was the variable of interest. Priming effects are obtained in normal subjects and schizophrenia patients, regardless of the implicit test used. However, a dissociation in priming between normal and patient groups was observed, depending on the test used. For word fragment test, priming was identical between the two groups. However, for word production, priming obtained in schizophrenics was lower than priming in normal controls. Results confirm a dissociation effect in implicit memory tests. These results could be explained in the context of the Roediger and Blaxton (1987) distinction between data-driven and conceptually-driven processing. This evidence suggests that a complete neuropsychological assessment of memory in schizophrenia should include different kinds of implicit memory tests (procedural, perceptual, and conceptual tasks). 相似文献

The purpose of this paper is to study the differential and complementary role played by the theory of planned behavior (TPB) variables and by participants' emotions when recalling and describing previous experiences of such risk behavior in the prediction of the intention to repeat a risk behavior in the immediate future. We chose the behavior of occasional excessive drinking, a risk behavior characterized by evoking attitudinal ambivalence and eliciting mixed emotions, joy and sadness. The results show that emotional ambivalence is not equivalent to attitudinal ambivalence (whose indexes include that of the affective component), and that this emotional information is relevant for predicting the intention to repeat the risk behavior in the near future, enhancing the prediction of the TPB model. 相似文献

A problem for many organizations is the low continuity of volunteers. Diverse theoretical models have been developed to explain sustained volunteerism, but most of these models have focused on the study of welfare volunteerism and not have verified whether their results could be generalized to other types of volunteerism. In this study, we propose a basic model to explain sustained volunteerism in any type of volunteerism. The aim of this study is to examine this basic model empirically in a sample of socio-assistential volunteers and in a sample of environmental volunteers. For this purpose, 290 volunteers completed a questionnaire and subsequently, two telephone follow-ups were carried out to determine whether the volunteers remained in the NGO one year later. The results show that the basic model offers an acceptable explanation of sustained volunteerism in the two types of volunteer samples studied, but it accounted for a low percentage of variance of the duration of service in both samples. Various relevant implications for the practical management of volunteerism in organizations are derived from theses findings. 相似文献
