Humans possess an invaluable ability of self-expression that extends into visual, literary, musical, and many other fields of creation. More than any other profession, artists are in close contact with this subdomain of creativity. Probably one of the most intriguing aspects of creativity is its negative correlation with the availability of monetary reward. The aim of this study was to investigate the reactivity of the dopaminergic reward system in artists and nonartist controls using the desire-reason-dilemma (DRD) paradigm, which allows separate evaluation of reactivity to the acceptance and rejection of rewards. Using fMRI, blood-oxygen-level-dependent (BOLD) responses were measured in key regions of the reward system, namely the ventral striatum (VS), the ventral tegmental area (VTA), and the anterior ventral prefrontal cortex (AVPFC). In contrast to controls, artists presented significantly weaker VS activation in reward acceptance. Additionally, they showed stronger suppression of the VS by the AVPFC in reward rejection. No other differences in demographic or behavioral data were evidenced. These results support the existence of characteristic neural traits in artists, who display reduced reactions to monetary reward acceptance and increased reactions to monetary reward rejection. 相似文献

This paper explores patients’ views and experiences of undergoing treatment-focused BRCA1 and BRCA2 genetic testing (TFGT), either offered following triaging to clinical genetics (breast cancer) or as part of a mainstreamed care pathway in oncology (ovarian cancer). Drawing on 26 in-depth interviews with patients with breast or ovarian cancer who had undergone TFGT, this retrospective study examines patients’ views of genetic testing at this point in their care pathway, focusing on issues, such as initial response to the offer of testing, motivations for undergoing testing, and views on care pathways. Patients were amenable to the incorporation of TFGT at an early stage in their cancer care irrespective of (any) prior anticipation of having a genetic test or family history. While patients were glad to have been offered TFGT as part of their care, some questioned the logic of the test’s timing in relation to their cancer treatment. Crucially, patients appeared unable to disentangle the treatment role of TFGT from its preventative function for self and other family members, suggesting that some may undergo TFGT to obtain information for others rather than for self. 相似文献

The International Society of Krishna Consciousness (ISKCON), commonly known as the Hare Krishna Movement, has disseminated a flurry of antievolutionist media since its inception in 1966. Such communications frequently co‐opt arguments employed by Christian creationists and Intelligent Design theorists. At the same time, however, there are indications that a scattering of ISKCON publications have articulated relatively ambiguous, less oppositional statements about evolutionary theory. This article reconsiders ISKCON's Darwin‐skepticism by appraising recent, largely unexamined Hare Krishna publications, as well as responses to evolutionary theory expressed by ISKCON's founder, A. C. Bhaktivedanta, and his immediate Vaishnava forerunners. The analysis reveals that, although the majority of contemporary ISKCON materials are vehemently opposed to evolution, some leading voices demonstrate less combative, cautiously accommodating stances. These cases are suggestive of complexities in ISKCON's responses to evolution, both past and present, which are not necessarily encapsulated in the terms Vedic creationism or antievolutionism. 相似文献

Global matching models have provided an important theoretical framework for recognition memory. Key predictions of this class of models are that (1) increasing the number of occurrences in a study list of some items affects the performance on other items (list-strength effect) and that (2) adding new items results in a deterioration of performance on the other items (list-length effect). Experimental confirmation of these predictions has been difficult, and the results have been inconsistent. A review of the existing literature, however, suggests that robust length and strength effects do occur when sufficiently similar hard-to-label items are used. In an effort to investigate this further, we had participants study lists containing one or more members of visual scene categories (bathrooms, beaches, etc.). Experiments 1 and 2 replicated and extended previous findings showing that the study of additional category members decreased accuracy, providing confirmation of the category-length effect. Experiment 3 showed that repeating some category members decreased the accuracy of nonrepeated members, providing evidence for a category-strength effect. Experiment 4 eliminated a potential challenge to these results. Taken together, these findings provide robust support for global matching models of recognition memory. The overall list lengths, the category sizes, and the number of repetitions used demonstrated that scene categories are well-suited to testing the fundamental assumptions of global matching models. These include (A) interference from memories for similar items and contexts, (B) nondestructive interference, and (C) that conjunctive information is made available through a matching operation. 相似文献

The Social Relations Model (SRM) is a conceptual and analytical approach to examining dyadic behaviors and interpersonal perceptions within groups. In an SRM, the perceiver effect describes a person's tendency to perceive other group members in a certain way, whereas the target effect measures the tendency to be perceived by others in certain ways. In SRM research, it is often of interest to relate these individual SRM effects to covariates. However, the estimated individual SRM effects might not provide a very reliable measure of the true, unobserved SRM effects, resulting in distorted estimates of associations with other variables. This article introduces a plausible values approach that allows users to correct for measurement error when assessing the association of individual SRM effects with other individual difference variables. In the plausible values approach, the latent, true individual SRM effects are treated as missing values and are imputed from an imputation model by applying Bayesian estimation techniques. In a simulation study, the statistical properties of the plausible values approach are compared with two approaches that have been used in previous research. A data example from educational psychology is presented to illustrate how the plausible values approach can be implemented with the software WinBUGS. 相似文献

A successful psychotherapy requires a good therapeutic relationship. An adequate operationalization by German diagnostic instruments has to be improved. A new instrument for measuring the therapeutic relationship from the patient’s perspective is presented. It is suitable for various therapeutic orientations, integrates current empirical findings in a broad theoretical framework and corrects methodological deficits of the existing German questionnaires. The therapeutic relationship questionnaire (ITB) was developed with a sample of 44 therapists and 519 inpatient, outpatient and day clinic patients. The ITB findings confirm a very good reliability (internal consistency and retesting reliability). There is initial evidence for convergent, divergent and differential validity and for associations with therapy effects. The ITB is an economic instrument that in contrast to other questionnaires measures a general factor which could be replicated in several confirmatory and exploratory factor analyses. 相似文献

Duration is a commonly measured dimension of behavior in behavioral research and clinical practice. An approach to studies of measurement in behavior analysis is to simulate streams of behavior from which samples can be extracted. It is therefore important to establish a typical range and distribution of behavioral durations on which simulated behavioral data should be based. We conducted an analysis of behavioral durations reported in the Journal of Applied Behavior Analysis between 2008 and 2012. The range and distribution of data points across different durations will be presented, as well as an analysis of the reliability of the software used to measure each data point.
