Conceptualizations of safer sex practices among young gay men (YGM) are frequently structured around communication between partners and the subsequent utilization or absence of condoms in a sexual encounter. Drawing on a sample of 34 in-depth interviews with YGM, ages 18 to 24, we explore the ways in which conceptualizations and definitions of safer sex are discussed and enacted. Placing attention on their safer sex practices, we analyze the conversations that do and do not occur among YGM and their partners, including the strategies (e.g., negotiated safety, condom communication and negotiation) that are commonly perceived as most useful by YGM. We provide recommendations regarding how to craft safer sex messages for YGM by considering their competing demands. 相似文献

Research has evidenced support for the spillover model, which asserts that parents' marital functioning influences their parenting and coparenting behavior in dyadic (mother-child and father-child) and triadic (mother-father-child) family contexts. However, few studies have simultaneously investigated the spillover model in both parenting and coparenting systems, preventing examination of whether spillover impacts both systems equally or differentially. Further, little research has examined whether quality of the marital system influences children's behavior toward their parents, as well as their parents' behavior, in dyadic interactions. We examined the spillover model using observational measures of parent and child behavior in parent-child dyadic interactions as well as coparenting in triadic interactions. We also explored parent and child gender differences in spillover effects. Participants were families with children aged 3 to 6 years (n = 149). Findings indicated that spillover occurs to multiple family systems, but the effects varied according to whose behavior (mother, father, child) was explored. In families of boys and girls, the marital system influenced warmth in triadic interactions, as well as fathers' responsiveness and children's responsiveness to mothers in dyadic interactions. Spillover effects were largely equivalent for girls and boys, but spillover to coparenting hostility in triadic interactions was limited to families raising girls. Parent gender also moderated associations between marital functioning and parent-child interactions: Spillover was significantly stronger for fathers' responsiveness (vs. mothers' responsiveness) and child responsiveness to mothers (vs. child responsiveness to fathers). 相似文献

Patients with frontal lobe damage and cognitively normal elderly individuals demonstrate increased susceptibility to false facial recognition. In this paper we review neuropsychological evidence consistent with the notion that the common functional impairment underlying face memory distortions in both subject populations is a context recollection/source monitoring deficit, coupled with excessive reliance on relatively preserved facial familiarity signals in recognition decisions. In particular, we suggest that due to the breakdown of strategic memory retrieval, monitoring, and decision operations, individuals with frontal lobe impairment caused by focal damage or age-related functional decline do not have a reliable mechanism for attributing the experience of familiarity to the correct context or source. Memory illusions are mostly apparent under conditions of uncertainty when the face cue does not directly elicit relevant identity-specific contextual information, leaving the source of familiarity unspecified or ambiguous. Based on these findings, we propose that remembering faces is a constructive process that requires dynamic interactions between temporal lobe memory systems that operate in an automatic or bottom-up fashion and frontal executive systems that provide strategic top-down control of recollection. Executive memory control functions implemented by prefrontal cortex play a critical role in suppressing false facial recognition and related source memory misattributions. 相似文献

In the trenches of real-world self-control: neural correlates of breaking the link between craving and smoking 总被引:1,自引:0,他引:1
Successful goal pursuit involves repeatedly engaging self-control against temptations or distractions that arise along the way. Laboratory studies have identified the brain systems recruited during isolated instances of self-control, and ecological studies have linked self-control capacity to goal outcomes. However, no study has identified the neural systems of everyday self-control during long-term goal pursuit. The present study integrated neuroimaging and experience-sampling methods to investigate the brain systems of successful self-control among smokers attempting to quit. A sample of 27 cigarette smokers completed a go/no-go task during functional magnetic resonance imaging before they attempted to quit smoking and then reported everyday self-control using experience sampling eight times daily for 3 weeks while they attempted to quit. Increased activation in right inferior frontal gyrus, pre-supplementary motor area, and basal ganglia regions of interest during response inhibition at baseline was associated with an attenuated association between cravings and subsequent smoking. These findings support the ecological validity of neurocognitive tasks as indices of everyday response inhibition. 相似文献

We leverage conservation of resources (COR) theory to explain how conscientiousness and emotional stability (ES) are associated with resource management strategies that may reflect instrumentally driven counterproductive work behaviour (CWB). Specifically, we investigated how the relationship between conscientiousness and CWB varies as a function of the level of available personal (i.e., ES) and organizationally provided (i.e., experienced job constraints) resources. Results from two surveys administered 4 weeks apart to US employees indicate that the negative relationship between conscientiousness and CWB is positive among employees who are low in ES. 相似文献

A cognitive model of bipolar disorder suggests that mental imagery acts as an emotional amplifier of mood and may be heightened in bipolar disorder. First, we tested whether patients with bipolar disorder would score higher on mental imagery measures than a matched healthy control group. Second, we examined differences in imagery between patients divided into groups according to their level of mood stability. Mood ratings over approximately 6-months, made using a mobile phone messaging system, were used to divide patients into stable or unstable groups. Clinician decisions of mood stability were corroborated with statistical analysis. Results showed (I) compared to healthy controls, patients with bipolar disorder had significantly higher scores for general mental imagery use, more vivid imagery of future events, higher levels of intrusive prospective imagery, and more extreme imagery-based interpretation bias; (II) compared to patients with stable mood, patients with unstable mood had higher levels of intrusive prospective imagery, and this correlated highly with their current levels of anxiety and depression. The findings were consistent with predictions. Further investigation of imagery in bipolar disorder appears warranted as it may highlight processes that contribute to mood instability with relevance for cognitive behaviour therapy. 相似文献

Experimental evidence using picture-word cues has shown that generating mental imagery has a causal impact on emotion, at least for images prompted by negative or benign stimuli. It remains unclear whether this finding extends to overtly positive stimuli and whether generating positive imagery can increase positive affect in people with dysphoria. Dysphoric participants were assigned to one of three conditions, and given instructions to generate mental images in response to picture-word cues which were either positive, negative or mixed (control) in valence. Results showed that the positive picture-word condition increased positive affect more than the control and negative conditions. Participants in the positive condition also demonstrated enhanced performance on a behavioural task compared to the two other conditions. Compared to participants in the negative condition, participants in the positive condition provided more positive responses on a homophone task administered after 24h to assess the durability of effects. These findings suggest that a positive picture-word task used to evoke mental imagery leads to improvements in positive mood, with transfer to later performance. Understanding the mechanisms underlying mood change in dysphoria may hold implications for both theory and treatment development. 相似文献

Substantial experimental evidence indicates that behavior reinforced on a denser schedule is more resistant to disruption than is behavior reinforced on a thinner schedule. The present experiment studied resistance to disruption in a natural educational environment. Responding during familiar activities was reinforced on a multiple variable-interval (VI) 7-s VI 30-s schedule for 6 participants with developmental disabilities. Resistance to disruption was measured by presenting a distracting item. Response rates in the disruption components were compared to within-session response rates in prior baseline components. Results were consistent with the predictions of behavioral momentum theory for 5 of 6 participants. 相似文献

Previous studies of couple therapy have conceptualized change as a gradual process. However, there is growing evidence that, for many clients, the majority of gains in other treatment modalities are often achieved between just 2 sessions. Isolating the frequency, nature, and predictors of these sudden gains (SGs) in couple therapy can add to a growing understanding of how and why couple therapy works. In a sample of 67 couples receiving treatment-as-usual couple therapy in two Veterans Affairs hospitals, 25% of individuals experienced a SG in relationship satisfaction. The magnitude of these SGs were large (d = 1.62) and fully explained the total pre-post change for individuals who experienced them. Individuals with SGs showed significantly greater satisfaction gains during therapy; however SGs were not related to relationship satisfaction or relationship status at 18-month follow-up. SGs were predicted by the content of the previous session, putative change mechanisms of communication, intimacy, and behavior, as well as the partner's SGs during the same period. Results suggest that SGs are an important component of change during couple therapy for some individuals, challenging the assumption of continuous change in previous studies. In addition, predictors of SGs were generally consistent with theoretical and empirical examinations of mechanisms of change in couple therapy. 相似文献

How does variability between members of a category influence infants’ category learning? We explore the impact of the order in which different items are sampled on category formation. Two groups of 10-months-olds were presented with a series of exemplars to be organized into a single category. In a low distance group, the order of presentation minimized the perceptual distance between consecutive exemplars. In a high distance group, the order of presentation maximized the distance between successive exemplars. At test, only infants in the High Distance condition reliably discriminated between the category prototype and an atypical exemplar. Hence, the order in which infants learnt about the exemplars impacted their categorization performance. Our findings demonstrate the importance of moment-to-moment variations in similarity during infants’ category learning. 相似文献
