Recently it has been claimed by Livingstone and Hubel that, of three anatomically and functionally distinct visual channels (the magnocellular, parvocellular interblob, and blob channels), only the magnocellular channel is involved in the processing of stereoscopic depth. Since the magnocellular system shows little overt colour opponency, the reported loss of the ability to resolve random-dot stereograms defined only by colour contrast seems consistent with this view. However, Julesz observed that reversed-contrast stereograms could be fused if correlated colour information was added. In the present study, 'noise' (non-corresponding) pixels were injected into random-dot stereograms in order to increase fusion time. All six subjects tested were able to achieve stereopsis in less than three minutes when there was only correspondence in colour and not in luminance, and three when luminance contrast was completely reversed. This ability depends on information about the direction of colour contrast, not just the presence of chromatic borders. When luminance and chromatic contrast are defined in terms of signal-to-noise ratios at the photoreceptor mosaic, chromatic information plays at least as important a role in stereopsis as does luminance information, suggesting that the magnocellular channel is not uniquely involved. 相似文献

Judges often evaluate stimulus series on dimensions for which no physical scale exists; for example, when judging academic ability in oral examinations. We propose that judges deal with this problem by calibrating an internal judgment scale that maps stimulus input onto available judgment categories. This calibration process implies serial position effects: Judges should initially avoid extreme categories, because using extreme categories reduces judgmental degrees of freedom, thereby increasing the possibility of internal consistency violations. In four experiments, we show that judgments become indeed more extreme later in a series of judgments. Judges evaluated the same good (poor) performances more positive (negative) at the end of a sequence compared to the beginning. Judges’ expertise did not prevent the effect, but allowing end-of-sequence judgments reduced serial position effects. We discuss the implications and possible remedies of these calibration effects on judgment extremity. 相似文献

There is much evidence to suggest that psychological and social issues are predictive of pain severity, emotional distress,
work disability, and response to medical treatments among persons with chronic pain. Psychologists can play an important role
in the identification of psychological and social dysfunction and in matching personal characteristics to effective interventions
as part of a multidisciplinary approach to pain management, leading to a greater likelihood of treatment success. The assessment
of different domains using semi-structured clinical interviews and standardized self-report measures permits identification
of somatosensory, emotional, cognitive, behavioral and social issues in order to facilitate treatment planning. In this paper,
we briefly describe measures to assess constructs related to pain and intervention strategies for the behavioral treatment
of chronic pain and discuss related psychiatric and substance abuse issues. Finally, we offer a future look at the role of
integrating pain management in clinical practice in the psychological assessment and treatment for persons with chronic pain. 相似文献

The paper discusses varieties of group therapies with refugees and torture survivors and the logic behind enhancing traditional group therapies to fit the unique experiences of refugees and torture survivors. It discusses some lessons learned from practice and from empirical research and some recommended adaptations. Finally, it discusses the Center for Torture and Trauma Survivors' therapy group model for torture survivors and describes two of its variants: The Bashal group for African and Somali women and the Bhutanese multi-family therapy group. Group therapies, in this model, extend to community healing. One of the essential and innovative features of the model is that it focuses not only on treating individual psychopathology but also extends to community healing by promoting the development of social clubs and organizations that promote the values and culture of the graduates of the therapy group and the continuation of social support. New graduates from the group join the club and become part of the social advocacy process and of group and community support and healing. This model adds an ecological dimension to the traditional group therapy. 相似文献

Loneliness has been shown to be inversely correlated with empathy in younger adults. The present study extends previous research by investigating the association between empathy and loneliness across the adult lifespan and examining the role of relevant demographic and personality factors. 110 community-dwelling adults (18 to 81 years old) completed the UCLA Loneliness Scale and the Empathy Quotient. Empathy scores were inversely associated with rated loneliness and predicted 8.7% of variance in loneliness scores after accounting for sex, age, relationship status, education, and neuroticism. The Social Skills factor of the Empathy Quotient was the strongest predictor of the association between perceived empathy and loneliness. Previous research is extended by the finding that rated loneliness was inversely associated with empathy scores across the adult lifespan. Underlying this relationship may be negative perceptions of personal social proclivity as a function of difficulty in understanding the mental states of others and high trait neuroticism. 相似文献

Genetic counseling and testing for hereditary breast cancer have the potential benefit of early detection and early interventions in African American women. However, African American women have low use of these services compared to White women. We conducted two focus groups with African American women diagnosed with breast cancer (affected group, n?=?13) and women with at least one first-degree relative with breast/ovarian cancer (unaffected group, n?=?8). A content analysis approach was employed to analyze interview data. Breast cancer survivors had more knowledge about genetic counseling and testing than participants who were unaffected with cancer. However, knowledge about genetic counseling was limited in both groups. Barriers to pursuing genetic counseling and testing included poor understanding of the genetic counseling and testing process, fear of carrying the mutation, concerns about discrimination, and cost. Motivators to participate in genetic counseling and testing included desire to help family members, insurance coverage, and potential of benefiting the larger African American community. Education efforts are needed to increase genetic counseling and testing awareness in the African American community. 相似文献

Researchers acknowledge mothers’ contributing role in influencing children’s behavioral displays of emotion, but there is a dearth in the literature on mothers’ emotion-related behaviors, beliefs, and needs. Urban, Head Start Mothers (n = 114) participated in a quantitative, exploratory investigation to examine child, maternal and community factors that may be associated with level of expressiveness, perceived role in emotional development, and receptivity to behavior support. Findings suggested that, compared to mothers raising two or more children, those raising only one child were significantly less positive in self-reported expressiveness, less supportive of the suggested role of mothers in the literature, and less receptive to parent-focused behavior support. Implications for acknowledging possibly distinct needs of Head Start mothers of singletons as well as seeking input from more experienced Head Start mothers in devising parenting interventions will be discussed. 相似文献
