Two experiments were performed having in common the use of sucrose concentration and volume as amount of reinforcement variables, and in situations permitting contrast between concentrations. The following conclusions are reached:

1. It is important to distinguish between the case in which separate subjects are exposed to different concentrations or volumes, and the case in which the same subjects receive different concentrations and volumes.

2. A distinction must be drawn between reinforcement contingencies in which force of response is or is not systematically related to concentration received. In nonforce contingent situations, emitted force is inversely related to concentration, when the same subjects are exposed to the different concentrations. In contingent situations, the relationship tends to be direct.

3. Rate and force of response vary inversely with nonforce contingent volume of sucrose reinforcement, when the same subjects are exposed to the different volumes.

4. Regardless of concentration and volume used, and presumably because of within-session satiation effects, there is a general tendency for rate to decline during nonforce contingent sessions.  相似文献

The Brief Fear of Negative Evaluation Scale (BFNE; M. R. Leary, 1983a) is often used to assess fear of negative evaluation, the core feature of social anxiety disorder. However, few studies have examined its psychometric properties in large samples of socially anxious patients. Although the BFNE yields a single total score, confirmatory factor analysis indicated a 2-factor solution to be more appropriate, with the 1st factor consisting of all straightforwardly worded items (BFNE-S) and the 2nd of all reverse-scored items (BFNE-R). Support was obtained for the convergent and discriminant validity of the BFNE and BFNE-S, but not the BFNE-R. These results suggest that standard scoring of the BFNE may not be optimal for patients with social anxiety disorder.  相似文献

Using Conger’s family stress model as a theoretical framework, a series of mediated associations among economic hardship, perceived economic pressure, parental depression, marital conflict, psychologically controlling parenting, and children’s reticent behaviors in Romanian families were studied. The sample consisted of 121 Romanian mothers and fathers of 4–5-year-old children. Children’s kindergarten teachers living in urban and rural locations evaluated child reticence. Findings generally support the family stress model. Structural equation modeling showed that after controlling for living in a rural location, economic pressure was indirectly linked with marital conflict through depression. Depression was indirectly related to psychological control through marital conflict, and marital conflict was indirectly linked to child reticence through psychological control. Directions for future research and recommendations for interventions and public policy are described.  相似文献

The current study evaluated the relationships among spiritual beliefs, religious practices, physical health, and mental health for individuals with stroke. A cross-sectional analysis of 63 individuals evaluated in outpatient settings, including 32 individuals with stroke and 31 healthy controls was conducted through administration of the Brief Multidimensional Measure of Religiousness/Spirituality (BMMRS) and the Medical Outcomes Scale-Short Form 36 (SF-36). For individuals with stroke, the SF-36 General Mental Health scale was significantly correlated with only the BMMRS Religious and Spiritual Coping scale (r = .43; p < .05). No other BMMRS factors were significantly correlated with SF-36 mental or physical health scales. Non-significant trends indicated spiritual factors were primarily related to mental versus physical health. This study suggests spiritual belief that a higher power will assist in coping with illness/disability is associated with better mental health following stroke, but neither religious nor spiritual factors are associated with physical health outcomes. The results are consistent with research that suggests that spiritual beliefs may protect individuals with stroke from experiencing emotional distress.  相似文献

Ecological valence theory (EVT; Palmer & Schloss, Proceedings of the National Academy of Sciences 107:8877–8882, 2010) proposes that color preferences are due to affective responses to color-associated objects: That is, people generally like colors to the degree that they like the objects associated with those colors. Palmer and Schloss found that the average valence of objects associated with a color, when weighted by how well the objects matched the color (weighted affective valence estimates: WAVE) explained 80% of the variation in preference across colors. Here, we replicated and extended Palmer and Schloss’s investigation to establish whether color–object associations can account for sex differences in color preference and whether the relationship between associated objects and color preference is equally strong for males and females. We found some degree of sex specificity to the WAVEs, but the relationship between WAVE and color preference was significantly stronger for males than for females (74% shared variance for males, 45% for females). Furthermore, analyses identified a significant inverse relationship between the number of objects associated with a color and preference for the color. Participants generally liked colors associated with few objects and disliked colors associated with many objects. For the sample overall and for females alone, this association was not significantly weaker than the association of the WAVE and preference. The success of the WAVE at capturing color preference was partly due to the relationship between the number of associated objects and color preference. The findings identify constraints of EVT in its current form, but they also provide general support for the link between color preference and color–object associations.  相似文献

Exposure and response prevention (EX/RP) is an efficacious treatment for obsessive-compulsive disorder (OCD). However, patients often do not adhere fully to EX/RP procedures. Motivational interviewing (MI) has been shown to improve treatment adherence in other disorders. This pilot study used a randomized controlled design to examine whether MI can be successfully added to EX/RP and whether this intervention (EX/RP + MI) could improve patient adherence to between-session EX/RP procedures relative to EX/RP alone. Thirty adults with OCD were randomized to 18 sessions of EX/RP or EX/RP + MI. Therapists rated patient adherence at each exposure session. Independent evaluators assessed change in OCD and depressive symptoms, and patients completed self-report measures of readiness for change and quality of life. The two treatment conditions differed in degree of congruence with MI but not in conduct of EX/RP procedures. Both groups experienced clinically significant improvement in OCD symptoms, without significant group differences in patient adherence. There are several possible reasons why EX/RP + MI had no effect on patient adherence compared to standard EX/RP, each of which has important implications for the design of future MI studies in OCD. We recommend that MI be further evaluated in OCD by exploring alternative modes of delivery and by focusing on patients less ready for change than the current sample.  相似文献

This essay argues that the “Heng Xian” bridges between two distinct discourses that were both prevalent in the late fourth century. One discourse focused on the origination of the natural world through a spontaneous process of differentiation, a position familiar from the Daodejing and “Tai yi sheng shui.” The other focused on the specific ways in which different kinds of things live, a position known primarily from Ru discussions centering on the concept of xing 性, the nature or spontaneous reactions of a particular kind of thing. The “Heng Xian” attempts to account for the specificity of human life—including language and social organization—while remaining within a naturalistic view grounded in spontaneity. The essay concludes by reflecting on what the “Heng Xian” tells us about the status of human institutions.  相似文献
