The left and right hemispheres of the brain are differentially related to the processing of emotions. Although there is little doubt that the right hemisphere is relatively superior for processing negative emotions, controversy exists over the hemispheric role in the processing of positive emotions. Eighty right-handed normal male participants were examined for visual-field (left-right) differences in the perception of facial expressions of emotion. Facial composite (RR, LL) and hemifacial (R, L) sets depicting emotion expressions of happiness and sadness were prepared. Pairs of such photographs were presented bilaterally for 150 ms, and participants were asked to select the photographs that looked more expressive. A left visual-field superiority (a right-hemisphere function) was found for sad facial emotion. A hemispheric advantage in the perception of happy expression was not found.  相似文献

The authors examined ratings of facial attractiveness, rankings of faces, and reasons given by young, middle-aged, and older men and women for young, middle-aged, and older male and female face attractiveness. No support for predictions derived from similarity, interest, and cohort hypotheses was obtained. In support of the expertise hypothesis, young and middle-aged adults rated younger faces as more attractive than old faces, whereas older adults rated all aged faces equally. In support of the crone hypothesis, older female faces were rated the lowest of all faces. Theoretical implications and real-world applications are discussed.  相似文献

Testosterone has been linked to a sexual preference for bodies rather than faces. Low digit ratio (2D:4D) and high facial width-to-height ratio (WHR) are associated with high prenatal testosterone. We tested whether low 2D:4D and high facial WHR were correlated with a preference for bodies over faces. Our sample consisted of 109 college students (64 males). A two-way analysis of variance demonstrated a significant main effect of digit ratio on the priority placed on paying attention to faces or bodies such that low 2D:4D was linked to a preference for bodies, but the effect of sex was not significant. There were no significant interaction effects. Another two-way analysis of variance revealed no significant effects for facial WHR and attentional priority but significant associations between sex and attentional priority. There were no significant interaction effects. Our findings indicate that individuals with low digit ratios tended to pay more attention to bodies than to faces compared with individuals with higher digit ratios, independently of sex. We also found that males tended to pay more attention to bodies than to faces compared with females, independently of facial WHR.  相似文献

The efficacy of cognitive‐behavioral therapy in multi‐cultural primary care patients with longstanding backache is not evaluated. The purpose of this study was to investigate the outcome of a four weekly‐treatment given by primary care physicians regarding pain‐related worry, depression and severe pain and to determine which social, clinical or gender factors were associated with outcome.The study group consisted of 245 patients in consecutive order from 19 countries, 18 to 45 years, entering rehabilitation program because of longstanding backache. Prevalences of pain‐related worry and depression and severe pain was counted and compared before and after. Logistic regression was used to calculate the odds (OR; 95% CI) for persistent pain‐related worry and/or persistent depression and severe pain (VAS ≥ 50). The prevalences of pain‐related worry and depression were both significantly lower after treatment (pain‐related worry 83% before vs. 38% after; depression 43% before vs. 31% after). Also the number of patients scoring ≥ 50 VAS was a little, but significantly, fewer (68% vs. 61%). Use of interpreter doubled the risk of having persistent pain‐related worry (OR 2.1; 95% CI 1.1–4.1) but the risk was not significant regarding persistent depression (OR 1.8; 0.6‐5.4). The rating of VAS rating ≥ 50 after treatment was twice as high, OR 2.3 (95% CI 1.1–4.6) in the 38–45 year old age group. To conclude, a focus on pain ideas reduced pain‐related worry and depression in these patients with various sociocultural backgrounds and longstanding backache.  相似文献

Abstract

Patients with positive physical findings to explain low back pain arc believed lo belong to two organic subgroups. One group has organic disease alone: in the other, organic disease is accompanied by psychological disturbance. Separation of patients with medical findings into groups with varying levels of psychological disturbance is difficult, because emotional disturbance is often hidden. In this study, the pain report of 124 patients with organic findings alone, and 50 patients with organic and psychological findings was examined to determine whether pain measurement could he used to identify accurately patients belonging 10 the two groups. the pain groups differed in the use of 43 pain words from the Low Back Pain Symptom Check List. Using a set of weights derived From discriminant analysis. the 33 pain words predicted 99.2% of the patients with organic disease alone and 86.0% of the patients with organic disease and psychological disturbance. The results were replicated in a new sample of 140 patients. Cross-validation shrinkage in accuracy was 8.3%. The results of the two studies suggest that pain measurement may he a useful clinical indicator of psychological disturbance in patients with organic findings.  相似文献

Aftereffects of adaptation have revealed both independent and interactive coding of facial signals including identity and expression or gender and age. By contrast, interactive processing of non-linguistic features in voices has rarely been investigated. Here we studied bidirectional cross-categorical aftereffects of adaptation to vocal age and gender. Prolonged exposure to young (~ 20 yrs) or old (~ 70 yrs) male or female voices biased perception of subsequent test voices away from the adapting age (Exp. 1) and the adapting gender (Exp. 2). Relative to gender-congruent adaptor-test pairings, vocal age aftereffects (VAAEs) were reduced but remained significant when voice gender changed between adaptation and test. This suggests that the VAAE relies on both gender-specific and gender-independent age representations for male and female voices. By contrast, voice gender aftereffects (VGAEs) were not modulated by age-congruency of adaptor and test voices (Exp. 2). Instead, young voice adaptors generally induced larger VGAEs than old voice adaptors. This suggests that young voices are particularly efficient gender adaptors, likely reflecting more pronounced sexual dimorphism in these voices. In sum, our findings demonstrate how high-level processing of vocal age and gender is partially intertwined.  相似文献

The present research examined the functional relations between the different dimensions of catastrophic thinking and pain-related disability, as a function of stage of chronicity. In the present study, 150 patients with chronic pain were grouped to form 3 different levels of chronicity: Group A (6 months to 2 years, n = 44); Group B (2-4 years, n = 55); and Group C (more than 4 years, n = 51). The 3 subscales of the Pain Catastrophizing Scale (Rumination, Magnification, Helplessness) were used as predictors of disability. Disability was assessed with the Pain Disability Index and pain was assessed with the McGill Pain Questionnaire. For Group A, regression analysis revealed that none of the PCS subscales predicted disability beyond the variance accounted for by sex, age and pain. Rumination was a significant predictor of disability in Group B, and both rumination and helplessness predicted disability in Group C. These findings provide preliminary evidence that stage of chronicity is an important moderator of psychological vulnerability for pain-related disability. Discussion addresses how the impact of pain management programs might be increased by tailoring interventions to specific patient needs.  相似文献

When confronted with multiple bistable stimuli at the same time, the visual system tends to generate a common interpretation for all stimuli. We exploit this perceptual-coupling phenomenon to investigate the perception of depth in bistable point-light figures. Observers indicate the global depth orientation of simultaneously presented point-light figures while the similarity between the stimuli is manipulated. In a first experiment, a higher occurrence of coupled percepts is found for identical figures, but coupling breaks down when either the movement pattern or both the viewpoint and the phase-relation are changed. A second experiment confirms these results, but also demonstrates that different point-light actions can be subject to perceptual coupling as long as they share the same viewpoint and exhibit equivalent degrees of perceptual ambiguity. The data are consistent with an explanation in terms of differential contributions of stored, view-dependent object and action representations and of an interaction between stages processing local stimulus features. The consequences of these results are discussed in the framework of an explicit model for the perception of depth in biological motion.  相似文献

ABSTRACT

The fan effect shows that memory is superior for information associated with few contexts relative to information associated with many contexts. The current study examined the fan effect within face recognition. Participants studied faces in which eye regions were associated with only one face (low-fan) or several faces (high-fan). Additionally, we examined whether featural fan might moderate in-group biases (i.e. in-group faces are better remembered than out-group faces). To this end, we manipulated occupation status (Experiment 1) and age (Experiment 2) of studied faces, and presented high- and low-fan faces. Results showed that low-fan faces were better remembered than high-fan faces. We did not detect an in-group bias as a function of occupation status, but there was a robust own-age bias. Fan type did not moderate the own-age bias, however. Although face recognition is sensitive to featural fan, the effect does not appear to differentially impact the own-age bias..  相似文献

The present research aimed to replicate and extend findings of Huijding, Muris, Lester, Field, and Joosse (2011), investigating whether symbolic approach–avoidance responses can induce implicit and explicit evaluation biases. Faces with a neutral expression were shown on a computer screen, and participants were instructed to repeatedly move a manikin towards some faces (approach) and away from other faces (avoidance). An affective priming task and a face rating task were used to assess training-compatible differences in implicit and explicit face evaluations, respectively. Results showed that the manikin training was successful: The priming task revealed more positive implicit evaluations of approached than avoided faces, and approached faces were rated more positively than avoided ones in the face rating task. These findings replicate those of Huijding and colleagues by demonstrating training effects on explicit evaluations, and they extend them by demonstrating effects on implicit evaluations.  相似文献
