奖惩线索条件下内外倾个体的自主唤醒和行为反应

将停止信号任务和金钱激励延迟任务相结合,使用16导生理记录仪记录被试的生理指标,探讨内外倾者在动机凸显情景下的生理唤醒特点以及反应调节能力。结果发现,隐含奖励和惩罚线索呈现之后,内外倾者的心率增快,内倾者的皮肤电活动显著增强。在停止信号任务中的优势反应阶段,内外倾者表现为对奖励凸显线索刺激的反应时缩短;而在非优势反应阶段,和外倾者相比较,内倾者的抑制反应错误率增高。表明内外倾者在奖惩线索条件下表现出不同的生理唤醒特点和行为反应。     

心算应激与特质焦虑、应对风格的关系

选取38名大学生为被试,采用BIOPAC多导生理记录仪,探讨心算应激对不同人格特质和应对风格的大学生心率（HR）、心率变异性（HRV）及皮肤电反应（GSR）的影响。实验采取2（人格特质：特质焦虑、非特质焦虑）×2（应对风格：注重情绪的应对、注重问题的应对）×3（实验阶段：基线期、任务期、恢复期）的三因素混合设计,要求所有被试经历5分钟的基线期、10分钟的心算任务期和5分钟的恢复期。结果表明：（1）特质焦虑的个体和注重情绪应对的个体在心算应激后的短时间内难以恢复到基线期的生理水平;（2）特质焦虑且注重情绪应对的个体在HR、HF、LF/HF及GSR上表现出明显强的反应性和弱的恢复性;（3）非特质焦虑且注重问题应对的个体在HF和GSR上表现出明显弱的反应性,在LF/HF和GSR上表现出明显强的恢复性。     

Rational Emotive Behavior Therapy (REBT) in the New Millenium: A Cross-Cultural Approach

This paper reviews and discusses the results of five cross-cultural studies in Colombia, Costa Rica, El Salvador, Spain, and USA, using 2 (college students vs. their parents) × 2 (males vs. females) MANOVA match group designs with the Attitudes and Beliefs Inventory subscales as dependent variables, two multicultural studies investigating the relationship between some demographic variables (Pan American Health Organization's Index of Violence, and Acculturation) and people's Irrationality, and two multidisciplinary studies on the relationship between some medical conditions (skin diseases, and severity of symptoms during menopause) and Irrational Beliefs.     

Cowden Syndrome

Cowden syndrome is an autosomal dominant inherited cancer syndrome characterized by multiple hamartomas which may develop in any organ. Mucocutaneous papillomas and trichilemmomas are hallmarks of the syndrome. Affected individuals are at high risk of developing both benign and malignant disease of the thyroid and breast. Epithelial thyroid carcinoma occurs in 3–10% of affected individuals while women have a 25–50% lifetime risk of developing adenocarcinoma of the breast. Because of the cancer risk, it is imperative that health care providers recognize Cowden syndrome. The susceptibility gene has been localized to 10q22-23 and preliminary studies demonstrate no genetic heterogeneity.     

不同照明条件下中国青年女性彩色图片的喜爱肤色

本研究采用类例判断法,在不同光源下对22张图片肤色样本逐一地进行主观评价。使用的照明光源为D65、CWF和A三种标准光源,色温分别为6500K、4150K和2856K。垂直照明,45°观察．肤色样本的视角为2°。实验结果表明：观察者在A光源下比D65光源更容易地评价肤色样本的质量,即在D65光源下的满意样本,在A光源下其喜爱程度趋于提高,而对不满意样本的喜爱程度趋于降低或基本相同;在三种照明条件下,被评为最佳肤色的样本与真实肤色有些偏离,色调略为偏黄,亮度较高,饱和度则非常接近;在肤色的波长范围内,亮度较高而饱和度偏低的肤色样本往往是优选样本。     

Reliability issues in the penile assessment of incarcerants

Although there has been increased reliance upon the direct physiological measurement of penile tumescence in the assessment of sexual deviations, the reliability of these measures has never been empirically validated. This investigation evaluates the reliability of the rape index as a technique in differentiating rapists from nonrapists. Eighteen individuals incarcerated on non-sexual-related offenses were presented visual and audio stimuli depicting mutually consenting intercourse, rape, and aggression. These stimuli were presented under two instructional sets: (1) enchance arousal and (2) suppress arousal. Reliability indices for the rape index were computed among various conditions of modality presentation, instructional set, and test-retest conditions. The overall reliability of the rape index was found to be low. The implications of these results upon the assessment and classification of offenders is discussed.     

Attractiveness as a Function of Skin Tone and Facial Features: Evidence from Categorization Studies

Participants rated the attractiveness and racial typicality of male faces varying in their facial features from Afrocentric to Eurocentric and in skin tone from dark to light in two experiments. Experiment 1 provided evidence that facial features and skin tone have an interactive effect on perceptions of attractiveness and mixed-race faces are perceived as more attractive than single-race faces. Experiment 2 further confirmed that faces with medium levels of skin tone and facial features are perceived as more attractive than faces with extreme levels of these factors. Black phenotypes (combinations of dark skin tone and Afrocentric facial features) were rated as more attractive than White phenotypes (combinations of light skin tone and Eurocentric facial features); ambiguous faces (combinations of Afrocentric and Eurocentric physiognomy) with medium levels of skin tone were rated as the most attractive in Experiment 2. Perceptions of attractiveness were relatively independent of racial categorization in both experiments.     

Mentalizing eye contact with a face on a video: Gaze direction does not influence autonomic arousal

Recent research has revealed enhanced autonomic and subjective responses to eye contact only when perceiving another live person. However, these enhanced responses to eye contact are abolished if the viewer believes that the other person is not able to look back at the viewer. We purported to investigate whether this “genuine” eye contact effect can be reproduced with pre‐recorded videos of stimulus persons. Autonomic responses, gaze behavior, and subjective self‐assessments were measured while participants viewed pre‐recorded video persons with direct or averted gaze, imagined that the video person was real, and mentalized that the person could see them or not. Pre‐recorded videos did not evoke similar physiological or subjective eye contact effect as previously observed with live persons, not even when the participants were mentalizing being seen by the person. Gaze tracking results showed, however, increased attention allocation to faces with direct gaze compared to averted gaze directions. The results suggest that elicitation of the physiological arousal in response to genuine eye contact seems to require spontaneous experience of seeing and of being seen by another individual.     

Brain asymmetry and autonomic conditioning: Sensitization control

In the present experiment we report effects of cerebral asymmetry, or laterality, during classical conditioning to facial emotional stimuli. Twenty-five female subjects were presented with slides of a happy face in one visual half-field (VHF), and simultaneously a slide of an angry face in the other VHF, followed by shock as the unconditioned stimulus (UCS). To control for effects of sensitization, a new stimulus, never associated with the UCS, was introduced in the extinction phase. Dependent measures were phasic heart rate responses (HR) and skin conductance responses (SCR). The HR results showed a significant right hemisphere effect for the CS-UCS association, that was not attributable to UCS sensitization. No significant effects were found for the SCRs. The basic HR finding was a right hemisphere superiority for learning of a conditioned association.
