A suite of programs is described for simulating the Rescorla-Wagner (1972) model of associative learning, the Solomon and Corbit (1974) opponent-process theory, and Schull’s (1979) extension of the latter. The programs are written for the Commodore 64 computer.  相似文献

In this commentary, I suggest that our work with women of color should be held together by three primary threads: (a) appreciation for history as we decipher and interpret the adaptive strategies of women of color; (b) recognition of the intersections of race, gender, and class as central to our work; and (c) self-critical examination of the meanings we attach to difference. The papers in the current special issue provide good examples regarding the importance of each thread. I argue that attention to these three themes should help us to keep our focus on contextually driven questions and to move forward our appreciation for the lives of women of color.  相似文献

Tucker, Damarin and Messick proposed a base-free measure of change which involves the computation of residual scores that are uncorrelated with true scores on the pretest. The present note discusses this change measure and demonstrates that, because of an incorrect derivation by the authors, properties they attribute to (the coefficient for the regression of true scores from the second testing on true scores from the first testing) are, in fact, properties ofb, the ordinary regression coefficient. A correct derivation of the initial position—change correlation in terms of is obtained, and Tucker et al.'s discussion of the law of initial values is reconsidered.The preparation of this paper was supported by the Learning Research and Development Center supported in part as a research and development center by funds from the National Institute of Education.  相似文献

This research is designed to assess the links between interpersonal behaviors and relationship development. A measure of friendship, labeled 'communion', was developed that focused exclusively on the characteristics of the relationship itself. It was hypothesized that greater use by both parties of behaviors promoting the interests of the other, 'beneficence', and of behaviors respecting the rights of the other, 'restraint', would result in greater communion between the roommates by the end of their first 6 months together. Both dimensions of behavior proved to be related to communion, although beneficence by both parties was relatively stronger than restraint. These findings were discussed in terms of other types of relationships where there is less freedom of involvement and greater hierarchy.  相似文献

Jealousy can consist of a broad range of experiences, from an everyday feeling to a pathology that causes abuse and crime. Although historically jealousy has been positively valued, century has seen an antijealousy crusade the effects of which can be noticed everywhere–with the exception of the legal system. Using Weiner's attributional model as theoretical background, a questionnaire research survey was conducted to determine if lay perception considers jealousy to be a justification of wife battery. Results show that current views of jealousy are negative and do not justify a mitigation in responsibility. Additionally differences by age and education can be found in the victim's attributed responsibility independently of the motivation. Implications for the legal system as well as for defensive attribution theory are discussed.  相似文献

National differences in subjective well-being (SWB) have been attributed to socioeconomic, climatic, and genetic factors. We focus on one particular facet of SWB—happiness or positive affect—measured by the nationally representative World Values Survey (WVS). We find that national percentages of very happy people across the three latest WVS waves (2000–2004, 2005–2009, 2010–2014) are consistently and highly correlated with national prevalence of the rs324420 A allele in the FAAH gene, involved in the hydrolysis of anandamide, a substance that reportedly enhances sensory pleasure and helps reduce pain. Climatic differences are also significantly associated with national differences in happiness, whereas economic wealth, recent economic growth, rule of law, pathogen prevalence, and the distribution of short versus long alleles in the serotonin transporter gene SLC6A4 are not significant predictors of national happiness.  相似文献

Previous research has demonstrated that changes in vocal frequency (pitch) influence judgments made about a speaker, although there is some question as to the relative importance of frequency to message content in person perception. Moreover, these studies have failed to examine the possible joint effect of frequency and individual differences in nonverbal sensitivity on person perception. The purpose of the present investigation was to examine the independent and joint effects of vocal frequency, perceptual salience, and nonverbal sensitivity (assessed by the Profile of Nonverbal Sensitivity) on person perception. Participants were assigned to one of nine experimental conditions and were asked to rate two male and two female speakers on seven unipolar adjective scales. The nine conditions were produced by factorially combining three levels each of salience (content, voice, control) and vocal frequency (decreased, increased, unmanipulated). The results of hierarchical multiple regression analyses indicated that variations in frequency did influence evaluative judgments of the speakers (competent, honest, persuasive), but that the magnitude of the influence varied as a function of the participants' levels of nonverbal sensitivity. The analyses, however, yielded no significant effects for participants' affective judgments, nor any significant effects involving perceptual salience.  相似文献

Although the notion of a down low life style, called various things at various times, has a long history in the black community, the past few years have been marked by an exponential increase in attention of this phenomenon in both the mainstream press and scholarly work. However, much of this work has focused on exploring whether men on the down low present a unique threat for HIV infection to black women. Currently, there exist very few scholarly works exploring the lives of black men who have sex with men and women that specifically address their own experiences living on the down low or how these men personally define what it means to be on the down low. In this article, we explore why black men who have sex with men and black men who have sex with men and women, including those who self-identify as gay, bisexual or as being on the down low, come to use the down low label and what it means to them to be on the down low.  相似文献
