Stress and self‐esteem have been shown to be important risk factors for adolescent cigarette smoking, and self‐esteem has previously been implicated as a stress‐moderating and a stress‐mediating variable. This study aimed to examine the associations between stress, area‐specific self‐esteem, and adolescent smoking, and to investigate whether specific areas of self‐esteem moderate or mediate the relationship between stress and smoking. Four hundred and ninety‐five adolescents (aged 14–19) responded to a questionnaire that examined these variables. Results showed that self‐esteem in the areas of school subjects and parent relations were related to smoking. Adolescents with low self‐esteem in these areas were more likely to smoke than their high self‐esteem counterparts. Highly stressed adolescents were more likely to smoke than those with low stress. However, the relationship between stress and smoking was completely mediated by self‐esteem in the area of school subjects. No moderation was revealed. Thus, high global self‐esteem may not be sufficient to reduce the risk of smoking. To maximise benefit, prevention and intervention efforts should target self‐esteem in the areas of school subjects and parent relations. Initiatives focusing on stress are only likely to decrease smoking to the extent that they influence self‐esteem in the area of school subjects.  相似文献

Social learning is considered one of the hallmarks of cognition. Observers learn from demonstrators that a particular behavior pattern leads to a specific consequence or outcome, which may be either positive or negative. In the last few years, social learning has been studied in a variety of taxa including birds and bony fish. To date, there are few studies demonstrating learning processes in cartilaginous fish. Our study shows that the cartilaginous fish freshwater stingrays (Potamotrygon falkneri) are capable of social learning and isolates the processes involved. Using a task that required animals to learn to remove a food reward from a tube, we found that observers needed significantly (P < 0.01) fewer trials to learn to extract the reward than demonstrators. Furthermore, observers immediately showed a significantly (P < 0.05) higher frequency of the most efficient “suck and undulation” strategy exhibited by the experienced demonstrators, suggesting imitation. Shedding light on social learning processes in cartilaginous fish advances the systematic comparison of cognition between aquatic and terrestrial vertebrates and helps unravel the evolutionary origins of social cognition.  相似文献

ObjectivesResearch has identified a decline in home advantage (HA) in a number of professional leagues since World War 2 (WW2). The purpose of the current study was to identify whether the decline in HA in English and Scottish Professional Football Leagues is mirrored by the radical transformation in the training of referees post-WW2, thus providing a new insight into the cause of HA.DesignA longitudinal quasi-experimental design.MethodsHA was calculated for each team at the end of every season for the four English and the Scottish Premier League post-WW2. We also compiled a list of events, statements and quotations to illustrate the dramatic change in the way referees have been trained (physically and psychologically), and assessed over the same period.ResultsWe observed a systematic decline in HA in professional English and Scottish leagues post-WW2, but with the steepest decline observed in lower divisions with smaller crowds. Of the factors thought to influence HA, crowd support appears the most consistent with these observations. Crowds are known to influence referees' decisions to favour the home side. However we argue that improved training of referees since WW2 has contributed to an improved ability to make objective decisions and a greater resilience to crowd influence, which explains the decline in HA but also accounts for the steeper decline observed with smaller crowds.ConclusionsThe continued existence of HA, and the less steep decline observed in top leagues suggests that referees' judgements are still not immune to the influence of larger crowds.  相似文献

Conflicting theoretical approaches yield divergent predictions about the effects of telephones versus computer-mediated communication (CMC) in the persistence or dissipation of pre-interaction expectancies. Moreover, different theoretical orientations and their underlying assumptions often invoke different methodologies, which can bias the results of research. The current studies articulate and assess rival hypotheses from alternative theoretical paradigms to uncover how CMC and vocal communication affect interpersonal impressions. Methodological issues in past CMC research are evaluated that limit the generalizability of previous findings in the area. Experiments employing alternative assumptions and methods indicate that CMC is functionally equivalent to vocal communication in its ability to ameliorate expectancies and that in some cases it can be superior in transmitting positive impressions.  相似文献

The dual-representation model of posttraumatic stress disorder (PTSD; Brewin, Gregory, Lipton, & Burgess, Psychological Review, 117, 210-232 2010) argues that intrusions occur when people fail to construct context-based representations during adverse experiences. The present study tested a specific prediction flowing from this model. In particular, we investigated whether the efficiency of temporal-lobe-based spatial configuration learning would account for individual differences in intrusive experiences and physiological reactivity in the laboratory. Participants (N = 82) completed the contextual cuing paradigm, which assesses spatial configuration learning that is believed to depend on associative encoding in the parahippocampus. They were then shown a trauma film. Afterward, startle responses were quantified during presentation of trauma reminder pictures versus unrelated neutral and emotional pictures. PTSD symptoms were recorded in the week following participation. Better configuration learning performance was associated with fewer perceptual intrusions, r = ?.33, p < .01, but was unrelated to physiological responses to trauma reminder images (ps > .46) and had no direct effect on intrusion-related distress and overall PTSD symptoms, rs > ?.12, ps > .29. However, configuration learning performance tended to be associated with reduced physiological responses to unrelated negative images, r = ?.20, p = .07. Thus, while spatial configuration learning appears to be unrelated to affective responding to trauma reminders, our overall findings support the idea that the context-based memory system helps to reduce intrusions.  相似文献

This article explores some implications of practicing therapy from a discourse perspective. In particular, the dialogues of therapy are portrayed as a context in which client and therapist practice culture. Therapy, from this perspective, can optimally take place in an imaginary dialogic meeting place--a "borderzone"--wherein the discussions of therapy can occur in respectful ways. Discursive therapists are encouraged to see the differends, or potential stuck times of therapy, as times to turn to alternative discourses to keep the dialogue resourceful and collaborative.  相似文献

Contemporary constructivism occurs at the confluence of three tributaries of thought and practice: hermeneutics, phenomenology, and linguistic philosophy. Selectively tracing the contributions of each tributary, or tradition of thought, a case is made for integrating cultural meanings and customs, lived experience, and people's uses of language in a generative and socially grounded approach to constructivism.  相似文献

When people think about how a situation might have turned out differently, they tend to imagine counterfactual alternatives to their actions. We report the results of three experiments which show that people imagine alternatives to actions differently when they know about a reason for the action. The first experiment (n = 36) compared reason – action sequences to cause – effect sequences. It showed that people do not imagine alternatives to reasons in the way they imagine alternatives to causes: they imagine an alternative to an action more than an effect, and to a cause more than a reason. The second experiment (n = 214) and the third experiment (n = 190) both show that different sorts of reasons have different sorts of effects on how people imagine alternatives to actions. People imagine an alternative to an action (the protagonist went to a ball) less often when they know the reason for the action was an obligation (he had to participate in fundraising) compared to when they know about a weaker reason (he wanted to meet a famous violinist) or no reason. The second experiment shows the effect for a social obligation and the third experiment replicates and extends it to a health obligation. We interpret the results in terms of the possibilities that people keep in mind about actions and their reasons.  相似文献

In this article we consider therapeutic conversations about suffering and sexual identity through an ethical and practical lens we refer to as ‘othering’ and ‘selving’. The ethical lens is shaped by recent developments in discursive theory and approaches to therapy. Our practical lens draws from research by discourse analysts showing how conversational practices feature in consequential ways in delicate discussions such as those about suffering and sexual identity. After helping readers understand these lenses we then use them in examining actual discussions about identity and suffering. We conclude with some general ideas and reflective questions for therapists wishing to extend these kinds of sensitivities and conversational practices in their work with clients.  相似文献
