抑制功能在疼痛中的作用

自生物心理社会模型提出以来, 利用心理因素预防和治疗疼痛备受关注, 越来越多的研究表明抑制功能在疼痛发展和恢复阶段起关键作用。疼痛诱发的自我防御机制通过争夺认知资源影响抑制功能, 反之低抑制功能个体在应对疼痛干扰中表现较差, 进而影响着疼痛的预期和学习。现有关于抑制功能影响疼痛的研究主要基于相关设计, 未来应进一步明确二者的因果关系。深入理解疼痛与抑制功能相互作用的认知机制有助于指导抑制功能对慢性疼痛的靶向干预。     

Emotion experience and regulation in China and the United States: How do culture and gender shape emotion responding?

Culture and gender shape emotion experience and regulation, in part because the value placed on emotions and the manner of their expression is thought to vary across these groups. This study tested the hypothesis that culture and gender would interact to predict people's emotion responding (emotion intensity and regulatory strategies). Chinese (n=220; 52% female) and American undergraduates (n=241; 62% female) viewed photos intended to elicit negative emotions after receiving instructions to either "just feel" any emotions that arose (Just Feel), or to "do something" so that they would not experience any emotion while viewing the photos (Regulate). All participants then rated the intensity of their experienced emotions and described any emotion-regulation strategies that they used while viewing the photos. Consistent with predictions, culture and gender interacted with experimental condition to predict intensity: Chinese men reported relatively low levels of emotion, whereas American women reported relatively high levels of emotion. Disengagement strategies (especially distancing) were related to lower emotional intensity and were reported most often by Chinese men. Taken together, findings suggest that emotion-regulation strategies may contribute to differences in emotional experience across Western and East Asian cultures.     

Relationships Among Spirituality, Religious Practices, Personality Factors, and Health for Five Different Faith Traditions

To determine: (1) differences in spirituality, religiosity, personality, and health for different faith traditions; and (2) the relative degree to which demographic, spiritual, religious, and personality variables simultaneously predict health outcomes for different faith traditions. Cross-sectional analysis of 160 individuals from five different faith traditions including Buddhists (40), Catholics (41), Jews (22), Muslims (26), and Protestants (31). Brief multidimensional measure of religiousness/spirituality (BMMRS; Fetzer in Multidimensional measurement of religiousness/spirituality for use in health research, Fetzer Institute, Kalamazoo, 1999); NEO-five factor inventory (NEO-FFI; in Revised NEO personality inventory (NEO PI-R) and the NEO-five factor inventory (NEO-FFI) professional manual, Psychological Assessment Resources, Odessa, Costa and McCrae 1992); Medical outcomes scale-short form (SF-36; in SF-36 physical and mental health summary scores: A user??s manual, The Health Institute, New England Medical Center, Boston, Ware et al. 1994). (1) ANOVAs indicated that there were no significant group differences in health status, but that there were group differences in spirituality and religiosity. (2) Pearson??s correlations for the entire sample indicated that better mental health is significantly related to increased spirituality, increased positive personality traits (i.e., extraversion) and decreased personality traits (i.e., neuroticism and conscientiousness). In addition, spirituality is positively correlated with positive personality traits (i.e., extraversion) and negatively with negative personality traits (i.e., neuroticism). (3) Hierarchical regressions indicated that personality predicted a greater proportion of unique variance in health outcomes than spiritual variables. Different faith traditions have similar health status, but differ in terms of spiritual, religious, and personality factors. For all faith traditions, the presence of positive and absence of negative personality traits are primary predictors of positive health (and primarily mental health). Spiritual variables, other than forgiveness, add little to the prediction of unique variance in physical or mental health after considering personality. Spirituality can be conceptualized as a characterological aspect of personality or a distinct construct, but spiritual interventions should continue to be used in clinical practice and investigated in health research.     

Convergent/Divergent Validity of the Brief Multidimensional Measure of Religiousness/Spirituality: Empirical Support for Emotional Connectedness as a “Spiritual” Construct

The objective of this article is to determine the convergent/divergent validity of the Brief Multidimensional Measure of Religiousness/Spirituality (BMMRS; Fetzer Institute & National Institute on Aging Working Group 1999) subscales by correlating it with the Temperament and Character Inventory (TCI) Self-Transcendence subscales (i.e., Mysticism, Transpersonal Identification, Self-Forgetfulness; Cloninger et al. 1994). The cross-sectional analysis of 97 undergraduate/graduate students from a Midwestern university was made. The results are (1) all five BMMRS spirituality subscales were significantly correlated with the TCI Mysticism scale; (2) two BMMRS scales (i.e., Daily Spiritual Experiences, Values/Beliefs) were significantly correlated with the TCI Transpersonal Identification scales; (3) no BMMRS spiritual subscales were significantly correlated with the TCI Self-Forgetfulness scale; and (4) of the BMMRS religion scales, only the Organizational Religiousness subscale was correlated with any TCI subscale (i.e., Mysticism). The BMMRS appears to have adequate convergent/divergent validity, although the need exists to determine specific dimensions of spirituality. Inspection of the specific items of the BMMRS and TCI spiritual subscales that were most consistently correlated (i.e., BMMRS Daily Spiritual Experiences, Values/Beliefs; TCI Mysticism, Transpersonal Identification) suggests the existence of a distinct spiritual construct that is best conceptualized as the experience of emotional connectedness to the divine, nature, and/or others.     

Mothers' affect dysregulation,depressive symptoms,and emotional availability during mother–infant interaction

Maternal affect dysregulation and maternal depressive symptoms were examined as predictors of maternal emotional availability (EA) during mother–infant interaction in a nonclinical sample. In particular, we investigated if affect dysregulation predicts EA and is more important than are depressive symptoms in predicting EA. Questionnaire measures and 30 min of free play were obtained from 46 mothers of 4‐ to 5‐month‐old infants. Mothers' self‐reported affect dysregulation was inversely related to EA, but mothers' depressive symptoms were not related to EA. More specifically, mothers' tendency to use unhealthy externalizing behaviors to reduce tension and distress predicted less EA. These results suggested that even in relatively low‐risk samples, mothers' self‐reported affect dysregulation, particularly the tendency to act out inappropriately in response to tension and distress, may be a more proximal predictor of EA than are depressive symptoms.     

Three-dimensional joint kinematics of ACL-deficient and ACL-reconstructed knees during stair ascent and descent

Mechanical environmental changes in the knee are induced by altered joint kinematics under cyclic loading during activities of daily living after anterior cruciate ligament (ACL) injury. This is considered a risk factor in progressive cartilage degeneration and the early onset of osteoarthritis following ACL injury and even after reconstructive surgery. The purpose of this study was to examine 3D joint kinematics of ACL-deficient and ACL-reconstructed knees to health controls during stair ascent and descent. A 3D optical video motion capture system was used to record coordinate data from reflective markers positioned on subjects as they ascended and descended a custom-built staircase. Spatiotemporal gait and knee joint kinematic variables were calculated and further analyzed. The ACL-deficient knees exhibited a significant extension deficit compared to the ACL-intact controls. A more varus and internally rotated tibial position was also identified in the ACL-deficient knees during both stair ascent and descent. The ACL-reconstructed knees exhibited less abnormality in both spatiotemporal gait parameters and joint kinematics, but these variables were not fully restored to a normal level. The kinematic profiles of the ACL-reconstructed knees were more similar to those of the ACL-deficient knees when compared to the ACL-intact knees. This suggests that the ACL-reconstructed knees had been "under-corrected" rather than "over-corrected" by the reconstructive surgery procedure. Findings from this study may provide more insight with respect to improving ACL reconstruction surgical techniques, which may aid the early progression of cartilage degeneration in ACL-reconstructed knees.

Turn of Fortune in Psychoanalysis: The 1924 Rank Debates and the Origins of Hermeneutic Psychoanalysis

The history of psychoanalysis can be characterized by conflicts that besides their personal content meant a closure and an opening in the development of the theorecial and practical (self )understanding of the discipline. The 1923-24 conflict that resulted in the separation of Rank from the movement and showed the first signs of uneasiness against the mainstream of psychoanalysis in Ferenczi's approach is relatively less known. However, its theoretical, or more general: discoursive impact on psychoanalysis was enormous.The debate took place among the top leaders of the movement, Rank and Ferenczi on one side, Jones, Abraham, Sachs on the other. In the center of the discussion there were two books, The Trauma of Birth by Rank and the The Development of Psychoanalysis by Ferenczi and Rank. With the help of documents I try to show that Freud first supported his Vienna-Budapest friends, later changed over to the other camp. As a general effect, I suggest that this debate resulted in the withdrawal from the earlier more hermeneutic-dialogical, therapy centered psychoanalysis toward a medical, objective, systematic and metapsychology oriented discipline. Besides the general theoretical change the power centers of psychoanalysis shifted toward West, Vienna and Budapest was substituted first by Berlin, later by London and New York.     

Time-dependent adhesion of a polydimethylsiloxane (PDMS) elastomer film to a flat indenter tip characterized using a cohesive-zone law

The work of adhesion between a polydimethylsiloxane (PDMS) elastomer film and a flat diamond tip was measured by instrumented indentation. The results showed that the apparent work of adhesion between the tip and the PDMS film increases with increasing dwell time and retreating velocity; on the other hand, the indentation depth has no significant effect on adhesion. The indentation experiment was analysed with viscoelastic finite element simulations with rate-dependent cohesive elements, from which the time evolution of adhesion was quantitatively implemented into a rate-dependent cohesive-zone law.
