How is chromatic contrast combined binocularly? One index of binocularity is the binocular contrast summation ratio (BCSR), which is the improvement in contrast sensitivity with binocular rather than monocular presentation. Simmons and Kingdom (1998, Vision Research 38 1063-1071) noted that BCSRs with some red-green isoluminant stimuli were suggestive of full linear summation. This suggestion was investigated further in four subjects by measuring binocular and monocular contrast thresholds for the detection of 0.5 cycle deg(1) isoluminant (red-green) and isochromatic (yellow-black) Gabor patches. These Gabor patches had either vertically or horizontally oriented carrier gratings and were either dichoptically in phase (same coloured bars in binocular correspondence) or in dichoptic anti-phase (opposite coloured bars in binocular correspondence). Full linear summation would be indicated by BCSRs of 2 for the in-phase and close to 0 for the anti-phase conditions. Mean BCSRs at isoluminance were 1.93 and 0.90, respectively, for the in-phase and anti-phase stimuli with horizontal carriers, the former being consistent with full linear summation, but the latter not. Despite these results, BCSRs obtained with isoluminant and isochromatic stimuli under similar conditions were not statistically distinguishable from each other, although there was a tendency for summation at isoluminance with in-phase stimuli to be higher and anti-phase stimuli to be lower. These data fall short of demonstrating full linear summation of chromatic contrast between the eyes under all presentation conditions, but they do indicate that there are strong binocular interactions at red-green isoluminance, which are similar to, and possibly even stronger than, those obtained with luminance stimuli.  相似文献

Previous studies reveal the reinforcement of gender stereotypes by picture books children read during the formative years. In these books, boys tend to be portrayed as active leaders, and girls as passive followers. Women and girls are under-represented. Men often exhibit career skills, and women perform traditional tasks in the home. Even when careers are nontraditional, personality characteristics and other qualities and behaviors are often stereotypical. Previous researchers emphasized the narrowly defined roles of women and children in picture books. In this study, we focused on the representation of mothers and fathers, and examined whether men are stereotyped as relatively absent or inept parents. A content analysis of the gender roles exhibited in 200 prominent childrens picture books demonstrated that fathers are largely under-represented, and, when they do appear, they are withdrawn and ineffectual parents. Further research could establish whether seriously deficient models of fatherhood in childrens literature affect the incidence of present, caring fathers in society.  相似文献

This paper describes the systemic use of a neurologically-based art therapy modality—bilateral art—that engages both dominant and non-dominant hands in the process of creating images in response to opposing cognitions or feelings. It describes both neuroscience and family therapy perspectives that argue for the use of bilateral art. A specific protocol for bilateral art therapy is provided along with a case study demonstrating integration of the protocol into the systemic treatment of a young family. Carole M.

International and minority populations tend to underutilize mental health services, including marriage and family therapy. Models of marriage and family therapy developed in the West may reflect Western values and norms inappropriate for diverse cultural contexts. This article presents an exploratory, qualitative study of a narrative therapy approach with Asian Indian women. This study adds to the small body of narrative-based empirical studies, and has a unique focus on intercultural applications and the experience of participants. Participant experience was examined along four phenomenological dimensions. Findings indicate the suitability of narrative interventions and nontraditional treatment delivery for this population.*This research was presented in 2004 at the annual conference of the American Association for Marriage and Family Therapy.  相似文献

This article portrays a model of family therapy clinical supervision using change theory that is most appropriate for use with the videotape, audiotape, case presentation and debriefing from the live session. The most powerful tool during this process is that of communication and assessment of change theorys tools of confidence and conviction. The concepts presented are meant to add an additional dimension to family therapy supervision in cooperation of other theories, not as an end in themselves.Special thanks to Ms. Geri Koncilja of the Informational Technology Center at Colorado State University, Pueblo for illustration and graphic assistance.  相似文献

The majority of scholarly management studies are based on self-report surveys. Consequently, the need to control for social desirability response is important, although few management studies in fact include the use of relevant scales commonly incorporated in psychology research. The full Marlowe–Crowne scale is disaffectingly long for senior-manager sample usage, so one of its short forms is more practical. However, the reliability of the most popular of these, the Strahan–Gerbasi scale, has not been tested with senior-manager samples. This study tests the scale amongst several senior-manager samples and finds it consistently lacks adequate reliability and unidimensionality.  相似文献

Virtual negotiations are expected to differ from face-to-face negotiations in terms of both negotiator behavior and outcomes. Nonetheless, competing theories and mixed results characterize this literature. This paper meta-analytically reviews studies that compared face-to-face negotiation with virtual negotiation (e.g., audio, email/text, video-conferencing). Competing predictions from psychological distance theory and the barrier effect perspective were tested. Overall, results supported the psychological distance theory in that face-to-face negotiations were less hostile and resulted in higher profit than virtual negotiations. Three moderators (negotiation mode, anonymity in virtual negotiation, and further interaction within the experiment) were hypothesized to impact virtual negotiation. While some moderators were significant, they did not completely account for findings across all studies. Results and discussion provide a note of caution for individuals embracing e-business and conducting Internet negotiations as well as suggestions for future research.An earlier version of this paper was presented at the 18th annual meeting of The Society for Industrial/Organizational Psychologists in Orlando, Fl 2003.

Most of the existing research on outcomes of job insecurity has identified individual-level burdens such as reduced attitudinal attachments toward work and well being. Far fewer studies have examined work-related outcomes that are of substantial concern to organizational success. In this paper, we investigated four new work-related outcomes of job insecurity that are part of the literature on key account management (KAM): customer performance, effectiveness with customers, adaptiveness to changing competitive conditions, and esprit de corps. A total of 353 U.S. based employees participated. The findings of this research suggest that job insecure workers perceive their organizations to be ineffective in delivering on all four KAM outcomes.  相似文献

We examined whether linear or non-linear LMX–job tension relationships existed, and if these effects were consistent across levels of negative (NA) and positive (PA) affect. Results indicated that NA and PA moderated the non-linear LMX–job tension relationship. Specifically, the LMX–job tension association was best depicted by an inverted-U form for high NAs. Tension was highest when LMX was moderate and lowest when LMX was either low or high. Tension increased minimally for low NAs across levels of LMX. For high PAs, the relationship was linear and inverse. Conversely, a U-shaped form best represented the LMX–job tension relationship for low PAs. Implications, strengths and limitations, and directions for future research are discussed.  相似文献

A review and critique of the Children’s Inventory of Anger (ChIA) is presented. The ChIA is a 39-item measure that operationalizes anger according to the conceptualization set forth by Ellis in Rational Emotive Behavior Therapy. The ChIA consists of four subscales (Frustration, Physical Aggression, Peer Relationships, and Authority Relations) which provide information regarding situations that are commonly associated with the experience of anger. Preliminary validity studies demonstrate that the ChIA has excellent reliability and high face validity. The forms are user friendly and easily scored, with norms tables conveniently located within the form. A computer-scoring program is available which significantly reduces clerical errors. The application of the instrument in practice is discussed. Due to the fact that the ChIA attempts to link assessment and intervention it should be useful in advancing the field in regard to treatment evaluation and substantiation of treatment validity. It is also expected to have considerable research utility.  相似文献
