In a recent article, Horlitz and O’Leary (1993) offer a reinterpretation of the results of several studies over the past 40 years that have employed the prolonged-inspection technique in the investigation of reversible figures. Specifically, they contend that, contrary to the favored interpretation of neural adaptation effects, the results of these studies reveal the combined influence of such topdown processes as attention and perceptual learning as well as such methodological difficulties as unwanted demand characteristics. In this note, we examine their analysis of the literature, their alternative theoretical model, and the supporting conclusions they draw from their two experiments. We argue that there is considerable evidence from a variety of studies for the joint role of bottom-up and top-down processes in reversible figures. Moreover, we propose that Horlitz and O’Leary’s own research, rather than eliminating the possibility of neural-adaptation effects, is best conceptualized as providing additional evidence for the role of higher-order processes in these phenomena. 相似文献

Latent Structure of the Sources of Mathematics Self-Efficacy 总被引:2,自引:0,他引:2

General social cognitive theory and its career-specific elaborations posit four primary sources through which self-efficacy beliefs are acquired and modified: personal performance accomplishments, vicarious learning, social persuasion, and physiological states and reactions. We present two studies exploring the dimensionality of these sources within the context of career-relevant mathematics activities. In Study 1, 295 college students completed measures of the source variables. Testing two- through five-factor models, we found strongest support for a four-factor latent structure of the efficacy sources. In Study 2, involving 481 high school students, a five-factor model fit the data well. We also found evidence of a higher order factor structure in both samples. Several directions for further research on the sources of efficacy information are considered, along with implications for career and academic interventions. 相似文献

The two primary theoretical explanations for the findings of the Milgram (1963, 1974) obedience studies are that of Milgram, stressing the role of relinquished responsibility to the authority on the one hand, and that of Mixon (1971, 1972), for whom trust in the experimenter is the key element on the other hand. The aim of the 2 studies reported in this article, using edited portions of the film Obedience (Milgram, 1965), was to explore the naive social perceiver's understanding of the dynamics of obedience to authority through his or her attributions about responsibility and trust, and thereby to provide some input into the theoretical controversy between Milgram and Mixon. Both studies were more supportive of Milgram's than of Mixon's position. 相似文献

The choice-making behavior of 5 young children with developmental disabilities who engaged in aberrant behavior was studied within a concurrent operants framework. Experimental analyses were conducted to identify reinforcers that maintained aberrant behavior, and functional communication training packages were implemented to teach the participants to gain reinforcement using mands. Next, a choice-making analysis, in which the participants chose one of two responses (either a mand or an alternative neutral response) to obtain different durations and qualities of reinforcement, was conducted. Finally, treatment packages involving choice making via manding were implemented to decrease inappropriate behavior and to increase mands. The results extended previous applications of choice making to severe behavior disorders and across behaviors maintained by positive and negative reinforcement. 相似文献

The purpose of this study was to learn more about the role of religious beliefs and practices in bereavement. Subjects were 312 adults each bereaved approximately one year. They were interviewed at the rate of about 50 per year over a 6 year period. Conclusions include: a) The opportunity to say goodbye to the deceased was significantly related to positive coping and outlook; (b) 47% of our subjects reported contact with the deceased following the death but such contact was not related to coping or outlook; c) grieving people are much more likely to turn to women than men for help; d) 77% said their religious beliefs were of considerable help in their grief. 相似文献

Background and objective: The intracarotid amobarbital procedure, or Wada test, is the method of choice to determine hemispheric representation of language, and is routinely used in the presurgical evaluation for intractable epilepsy. Some investigators perform comprehensive language assessments, but others base language lateralization solely on speech arrest. This study sought to determine whether speech arrest alone during Wada testing provides valid data regarding language lateralization. Methods: The subjects (previously reported) were 21 patients evaluated for intractable epilepsy, who underwent language lateralization by Wada testing and functional MRI (FMRI). For each patient, language representation was determined by calculating: (1) a Wada laterality index based exclusively on speech arrest; (2) a Wada laterality index based on comprehensive language assessment; and (3) an FMRI laterality quotient. Correlation coefficients and categorical classifications were analyzed. Results: There was no significant correlation between the Wada laterality quotient derived from duration of speech arrest and either the comprehensive Wada language laterality score (r= .35,p= .12) or FMRI language laterality score (r= .32,p= .16). Categorical classification as left, right or bilateral language also showed marked discordance between speech arrest and the other two methods. Conclusion: Duration of speech arrest during Wada testing is not a valid measure of language dominance. 相似文献

This study examines the managerial review of sexual harassment allegations by subordinates against supervisors as a 2-stage attribution process. In the 1st stage, reviewers decide whether the behavior was inappropriate (misconduct). In the 2nd, reviewers decide the level of company responsibility. The reviewers' 2 decisions are influenced in distinct ways by scenario participant job performance, and the genders and ethnicities of reviewer and scenario participants. Male respondents exhibited some bias for high-performing same-ethnicity supervisors—a bias not present in female responses. In the 2nd stage, female and non-White reviewers assessed significantly higher levels of company responsibility than did male and White respondents. The data suggest that although men and women do not differ substantially over what constitutes misconduct, they do differ over the company's responsibility. 相似文献

This study examined the relationships between racial identity attitudes and gender role conflict in a sample of 95 African American men ages 23–80 years old. Participants completed the 1981 Black Racial Identity Attitude Scale by Parham and Helms and the 1986 Gender Role Conflict Scale by O'Neil, Helms, Gable, David, and Wrightsman. Results indicated that racial identity attitudes were differentially related to patterns of gender role conflict when racial identity is externally defined. However, an internally defined racial identity had no relationship to gender role conflict. Results are discussed in terms of the significance of racial identity for understanding African American men's conflict associated with traditional male gender role standards and expectations. 相似文献
