Emotional rumination and inhibition were identified in the Emotion Control Questionnaire (ECQ—Roger and Nesshoever 1987; Roger and Najarian 1989) as two relatively independent dimensions of emotional style, and the two measures have subsequently been shown to be important moderator variables in a range of health and forensic settings. Two other dimensions that emerged in the ECQ, labelled aggression control and benign control, have been shown to form part of the extraversion constellation, and the present paper describes the construction and validation of a new scale focusing exclusively on rumination and inhibition. Revised and expanded item pools for the scales were subjected to exploratory and confirmatory factor analyses, which endorsed the two-factor structure. The new scales were validated concurrently against related scales in different samples, and were shown to be systematically related to two independent indices of health status. 相似文献

Learning about hereditary cancer may influence an individual’s self-concept, which otherwise represents a complex but stable
cognitive structure. Recently, a 20-statement self-concept scale, with subscales related to stigma-vulnerability and bowel
symptom-related anxiety, was developed for Lynch syndrome. We compared the performance of this scale in 591 mutation carriers
from Denmark, Sweden and Canada. Principal component analysis identified two sets of linked statements—the first related to
feeling different, isolated and labeled, and the second to concern and worry about bowel changes. The scale performed consistently
in the three countries. Minor differences were identified, with guilt about passing on a defective gene and feelings of losing
one’s privacy being more pronounced among Canadians, whereas Danes more often expressed worries about cancer. Validation of
the Lynch syndrome self-concept scale supports its basic structure, identifies dependence between the statements in the subscales
and demonstrates its applicability in different Western populations. 相似文献

A wealth of prior research has shown that testing can improve subsequent learning of the initially tested material. In contrast,
only one recent study has shown that an interim test over prior material can improve learning of subsequent new material (i.e.,
an interim-test effect). Five experiments replicated and extended this initial work by exploring the extent to which interim test effects generalize
to complex text material. Participants were prompted to recall each section of an expository text before moving on to study
the next section, or were only prompted to recall after the final section. In all experiments, recall of the final, target
section was greater when prior sections had received interim tests versus no interim tests. Experiment 3 established that the effect was due to interim testing in particular rather than to intervening activity in general. Experiment 4 established that the effect was not due to test expectancy differences. In contrast to prior research, Experiment 4 also provided evidence that the effect is not due to release from proactive interference. We discuss other possible mechanisms
underlying interim-test effects with text, including shifting to more effective encoding strategies. 相似文献

Spermidine (SPD) is an endogenous polyamine that modulates N-methyl-D-aspartate (NMDA) receptor function, and has been reported to facilitate memory formation. In the current study we determined whether or not the PKA/CREB signaling pathway is involved in SPD-induced facilitation of memory of inhibitory avoidance task in adult rats. The post-training administration of the cAMP-dependent protein kinase (PKA) inhibitor, N-[2-bromocinnamylamino)ethyl]-5-isoquinoline sulfonamide [H-89, 0.5 ρmol intrahippocampal (ih)] or the antagonist of the NMDA receptor polyamine-binding site (arcaine, 0.02 nmol ih) with SPD (0.2 nmol ih) prevented memory improvement induced by SPD. Intrahippocampal administration of SPD (0.2 nmol) facilitated PKA and cAMP response element-binding protein (CREB) phosphorylation in the hippocampus 180 min, but not 30 min, after administration, and increased translocation of the catalytic subunit of PKA into the nucleus. Arcaine (0.02 nmol) and H-89 (0.5 ρmol) prevented the stimulatory effect of SPD on PKA and CREB phosphorylation. These results suggest that memory enhancement induced by the ih administration of SPD involves the PKA/CREB pathways in rats. 相似文献

Our primary focus is on analysis of the concept of voluntariness, with a secondary focus on the implications of our analysis for the concept and the requirements of voluntary informed consent. We propose that two necessary and jointly sufficient conditions must be satisfied for an action to be voluntary: intentionality, and substantial freedom from controlling influences. We reject authenticity as a necessary condition of voluntary action, and we note that constraining situations may or may not undermine voluntariness, depending on the circumstances and the psychological capacities of agents. We compare and evaluate several accounts of voluntariness and argue that our view, unlike other treatments in bioethics, is not a value-laden theory. We also discuss the empirical assessment of individuals' perceptions of the degrees of noncontrol and self-control. We propose use of a particular Decision Making Control Instrument. Empirical research using this instrument can provide data that will help establish appropriate policies and procedures for obtaining voluntary consent to research. 相似文献

The present research evaluated an Italian version of the Body Image Concern Inventory (I-BICI). A total of 412 Italian volunteers from Central and Southern Italy completed the measure (M=27.05 years, range=13-66 years) and the basic psychometric properties (factor structure, internal consistency, convergent validity) were assessed. The total measure demonstrated good internal consistency. Significant correlations were found between the I-BICI and measures of eating disorder (EDI-2) and obsessive-compulsive symptomatology (PI). Confirmatory factor analysis replicated the mesaure’s proposed factor structure. Directions for future research are discussed. 相似文献

Emotional expression and how it is lateralized across the two sides of the face may influence how we detect audiovisual speech. To investigate how these components interact we conducted experiments comparing the perception of sentences expressed with happy, sad, and neutral emotions. In addition we isolated the facial asymmetries for affective and speech processing by independently testing the two sides of a talker's face. These asymmetrical differences were exaggerated using dynamic facial chimeras in which left- or right-face halves were paired with their mirror image during speech production. Results suggest that there are facial asymmetries in audiovisual speech such that the right side of the face and right-facial chimeras supported better speech perception than their left-face counterparts. Affective information was also found to be critical in that happy expressions tended to improve speech performance on both sides of the face relative to all other emotions, whereas sad emotions generally inhibited visual speech information, particularly from the left side of the face. The results suggest that approach information may facilitate visual and auditory speech detection. 相似文献

As the United States becomes increasingly diverse, interracial contact will become considerably less rare. Much research has suggested that interracial interactions are often stressful and uncomfortable for both Whites and racial minorities. Bringing together several bodies of research, the present article outlines a motivational perspective on the dynamics of intergroup contact. To this end, we consider the roles of three motivational mindsets that have the potential to shape interactions to be less cognitively depleting and more enjoyable for both interactants. In particular, we consider the effects of (i) approach and avoidance motivation (Handbook of Motivation and Cognition: Foundation of Social Behavior, 1990, New York: Guilford Press), (ii) promotion and prevention regulatory focus (American Psychologist, 52 , 1997, 1280), and (iii) learning and performance goals (Psychological Review, 95 , 1988, 256) in shaping the dynamics of interracial contact. We suggest that investigations into these motivational mindsets will offer further insight into how and why interracial interactions go awry and will assist in the development of strategies and interventions that facilitate more smooth and enjoyable contact experiences. 相似文献

During the last few decades we have witnessed a proliferation of exercises dealing with the public participation of citizens in various different dimensions of their societies, including issues of science and technology. On the one hand, these mechanisms provide more robust forms of public engagement with matters that were traditionally dealt with by experts; on the other hand, they raise concerns relating to their design, efficiency or potential for the empowerment of citizens. As part of the EC-funded project DEEPEN (Deepening Ethical Engagement and Participation in Emerging Nanotechnologies) a research team in Coimbra, Portugal, was put in charge of identifying the ethical and social “impacts” of emerging nanotechnologies, transforming the traditional focus groups through the incorporation of two methodological innovations: the Pedagogy of the Oppressed and the Theatre of the Oppressed. This article reflects on the outcomes and complexities of the introduction of these two methodologies. Since the participants had little or no information on nanotechnologies, we reflect on the politics of these focus groups by exploring how issues of intervention, subjectivity, representation and agency were interconnected during this exercise of public participation in Science and Technology, analyzing the role of social sciences in developing nanoethics. 相似文献
