Individual differences in the evaluation of affective stimuli, such as the positivity offset and negativity bias may have a biological basis. We tested whether two SNPs (HTR2A; 102T>C and HTR1A; 1019C>G) related to serotonin receptor function, a biological pathway associated with affective regulation, were differentially related to positivity offset and negativity bias for males and females. Participants were 109 cigarette smokers who rated a series of affective stimuli to assess reactions to positive and negative pictures. Gender × genotype interactions were found for both SNPs. Males with the 102T allele showed a greater positivity offset than males with the 102C allele. For females, in contrast, the 1019C allele was associated with a greater positivity offset than the 1019G allele, whereas the 102T allele was associated with a greater negativity bias than the 102C allele. Identifying how gender differences may moderate the effect of serotonin receptor genes on affective information processing may provide insight into their role in guiding behavior and regulating affect. 相似文献

A fully dimensional view of psychiatric disorder conceptualises schizotypy as both a continuous personality trait and an underlying vulnerability to the development of psychotic illness. Such a model would predict that the structure of schizotypal traits would closely parallel the structure of schizophrenia or psychosis. This was investigated in injecting amphetamine users (N = 322), a clinical population who have high rates of acute psychotic episodes and subclinical schizotypal experiences. Schizotypy was assessed using the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE), and psychotic symptoms were assessed using the Brief Psychiatric Rating Scale (BPRS). Using confirmatory factor analysis, O-LIFE subscale scores were mapped onto latent variables with their more clinical counterparts from the BPRS. A four-factor model comprising positive schizotypy, disorganisation, negative schizotypy, and disinhibition provided the best model fit, consistent with prior research into the structure of schizotypy. The model provided a good fit to the data, lending support to the theory that schizotypy and psychotic symptoms map onto common underlying dimensions. 相似文献

Individual beliefs and expectations regarding gender roles influence interpersonal behavior. If family therapists ignore or avoid discussions regarding gender roles, change may ultimately be inhibited. The Cognitive-Active Gender Role Identification Continuum (CAGRIC) is a framework that may facilitate a therapist's discussion of gender roles and the ways in which gender role expectations impact their clients’ relationships. Using data from the 2002 International Social Survey Program module on “Family and Changing Gender Roles,” this study examines the gender role classifications proposed by the CAGRIC model and the influence of gender role beliefs and behaviors on relationship satisfaction. Data from Australia, Brazil, Israel, Japan, Russia, Spain, and the United States are used to test the clustering and congruence hypotheses of the CAGRIC model. Results suggest support for the clustering hypothesis of the model, especially in Western countries. 相似文献

When relying on crime scene behaviours to link serial crimes, linking accuracy may be influenced by the measure used to assess across‐crime similarity and the types of behaviours included in the analysis. To examine these issues, the present study compared the level of linking accuracy achieved by using the simple matching index (S) to that of the commonly used Jaccard's coefficient (J) across themes of arson behaviour. The data consisted of 42 crime scene behaviours, separated into three behavioural themes, which were exhibited by 37 offenders across 114 solved arsons. The results of logistic regression and receiver operating characteristic analysis indicate that, with the exception of one theme where S was more effective than J at discriminating between linked and unlinked crimes, no significant differences emerged between the two similarity measures. In addition, our results suggest that thematically unrelated behaviours can be used to link crimes with the same degree of accuracy as thematically related behaviours, potentially calling into the question the importance of theme‐based approaches to behavioural linkage analysis.

The authors tested the effects of cues to action--messages intended to increase flu immunizations. North Dakota counties were randomly assigned to reminder letters, action letters, or no letters. Within the reminder-letter counties, Medicare recipients received either (a) a reminder from the state peer review organization (PRO) to obtain a flu shot or (b) a reminder from the PRO, framed either in terms of the loss associated with failing to get a shot or (c) the benefits associated with getting a shot. Within the action-letter counties, Medicare recipients leaned where and when to receive a flu shot. Reminder type failed to differentially affect the immunization rate (overall M = 24.5%). However, the action messages worked better (28.2%) than no message (19.6%). 相似文献

Law Enforcement Agencies gather intelligence in order to prevent criminal activity and pursue criminals. In the context of human intelligence collection, intelligence elicitation relies heavily upon the deployment of appropriate evidence-based interviewing techniques (a topic rarely covered in the extant research literature). The present research gained unprecedented access to audio recorded telephone interactions (N = 105) between Source Handlers and Covert Human Intelligence Sources (CHIS) from England and Wales. The research explored the mean use of various question types per interaction and across all questions asked in the sample, as well as comparing the intelligence yield for appropriate and inappropriate questions. Source Handlers were found to utilise vastly more appropriate questions than inappropriate questions, though they rarely used open-ended questions. Across the total interactions, appropriate questions (by far) were associated with the gathering of much of the total intelligence yield. Implications for practise are discussed. 相似文献
