Dental education programs are known to be highly stressful and stress can affect general health. The aims were to identify sources of stress among preclinical students and to evaluate their perceived levels of stress, self-efficacy and effective coping strategies in a private dental school. One hundred preclinical students in a Turkish private dental school were surveyed using dental environment stress (DES), perceived stress (PSS), general self-efficacy (G-SES) and brief coping scales (Brief-COPE). Age, gender, history of psychiatric treatment, factors that affected the choice of dentistry, choice rank of dental school, scholarship and income was recorded. ‘Exams and grades’ followed by ‘Fear of failing course or year’ were found to be the most stressprovoking factors. The most and the least stressprovoking DES domains were ‘Workload’ and ‘Social stressors’, respectively. ‘Social stressors’ affected male more than female (p < .05). The most and the least common coping strategies were found to be ‘Planning’, and ‘Drug’, respectively. Female used ‘Instrumental support’ more than male (p < .05). Demographic factors had impact on the perceived stress factors and levels, as well as coping strategies. Unlike previous studies establishing high stress levels in dental students, preclinical students displayed moderate level of stress. Clinical dental education might be more responsible for creating stress.  相似文献

Animate entities are often better remembered than inanimate ones. The proximal mechanisms underlying this animacy effect on recall are unclear. In two experiments, we tested whether the animacy effect is due to emotional arousal. Experiment 1 revealed that translations of the animate words used in the pioneering study of Nairne et al. (Psychological science, 24, 2099–2105, 2013) were perceived as being more arousing than translations of the inanimate words, suggesting that animacy might have been confounded with arousal in previous studies. In Experiment 2, new word lists were created in which the animate and inanimate words were matched on arousal (amongst several other dimensions), and participants were required to reproduce the animate and inanimate words in a free recall task. There was a tendency towards better memory for arousing items, but robust animacy effects were obtained even though animate and inanimate words were matched on arousal. Thus, while arousal may contribute to the animacy effect when it is not carefully controlled for, it cannot explain the memory advantage of animate items.  相似文献

Academic self-handicapping is a very popular subject of research in educational psychology, in which a growing number of related findings are reported. However, apart from a recent meta-analysis (Schwinger et al. in J Educ Psychol 106(3):744–761, 2014), the last comprehensive review of the subject was published 17 years ago (Urdan and Midgley in Educ Psychol Rev 13(2):115–138, 2001). This paper integrates relevant findings accumulated since then, which are discussed in a coherent interpretive framework. The first part of the paper discusses the definition and theoretical grounds of academic self-handicapping, then its manifestations in an academic context are enumerated. The second part of the study focuses on the self-protective function of stereotypes based on self-handicapping as well as on the impressions self-handicapping students may make on others at school. A summary of the contributions of goal orientation theory is provided in relation to self-handicapping, and the effects of various goal orientations and goal structures on academic performance are analysed. Based on an analysis of interactions between self-handicapping and academic performance, the authors argue for the importance of prevention and suggest possible ways to prevent self-handicapping. In conclusion, measurement issues of academic self-handicapping and the methodological paradox inherent in questionnaire measures are discussed.  相似文献

A popular strategy for meeting over-determination and pre-emption challenges to the comparative counterfactual conception of harm is Derek Parfit’s suggestion, more recently defended by Neil Feit, that a plurality of events harms A if and only if that plurality is the smallest plurality of events such that, if none of them had occurred, A would have been better off. This analysis of ‘harm’ rests on a simple but natural mistake about the relevant counterfactual comparison. Pluralities fulfilling these conditions make no difference to the worse for anyone in the over-determination cases that prompted the need for revising the comparative conception of harm to begin with. We may choose to call them harmful anyway, but then we must abandon the idea that making a difference to the worse for someone is essential to harming. I argue that we should hold on to the difference-making criterion and give up the plural harm principle. I offer an explanation of why Parfit’s and Feit’s plural harm approach seems attractive. Finally, I argue that the consequences of giving up the plural harm principle and holding on to the simple comparative counterfactual analysis of harm are less radical than we may think, in relation to questions about wrongness and responsibility.  相似文献

Psychological maltreatment is a dramatically increasing problem and related to a wide range of short-term and long-term outcomes. Considering these potential effects of it on healthy development and well-being, it is important to understand the mitigating factors for its negative effects on well-being from childhood to adulthood. Therefore, the purpose of present study is to investigate the mediation role of social acceptance and social connectedness on the effect of psychological maltreatment on subjective well-being in high school adolescents. The sample consisted of 825 students enrolled in grades 9–12 in two public schools in a small urban city in Turkey. The participants were 46.2% male and 53.8% female and ranged in age from 14 to 19 years old (M = 16.508, SD = 1.163). Findings from the structural model indicated that psychological maltreatment was a negative and significant predictor of social connectedness and social acceptance, yet did not significantly predict youth subjective well-being. Further, social acceptance and social connectedness were significant and positive predictors of subjective well-being. Finally, results showed that social acceptance and social connectedness fully mediated the relationship between psychological maltreatment and subjective well-being. Taken together, these outcomes support the importance of social connectedness and social acceptance on adolescents’ wellbeing, and these psychosocial resources help to explain the association between psychological maltreatment and subjective well-being. Results are discussed in light of the literature, and suggestions are presented for professions as well as for future research.  相似文献

This experiment investigates the emotional consequences of viewing strangers’ positive posts on Instagram. From a social comparison perspective, strangers’ positive posts on social media are expected to negatively affect viewers’ emotions. From an emotional contagion perspective, strangers’ positive posts should positively affect viewers’ emotions. The current lab experiment examines both the social comparison and the emotional contagion perspective while taking individual differences into account. Participants viewed positive, neutral, or no posts of confederates. In support of the social comparison perspective, individuals who tend to compare themselves to others reported lower positive affect if they had viewed positive posts than if they had viewed neutral or no posts. In support of the emotional contagion perspective, individuals who tend not to engage in social comparison reported higher positive affect after viewing positive posts than after viewing neutral or no posts. These findings indicate that individual differences in processing tendencies lead people to respond to social information on social media in opposite ways.  相似文献

Impulsivity is a multi-dimensional construct that is regarded as a symptom of many psychiatric disorders. Harm resulting from impulsive behaviour can be substantial for the individuals concerned, for their social network, and for wider society. Therefore, the importance of developing therapeutic interventions to target impulsivity is paramount. We conducted a systematic review and meta-analysis of the literature from AMED, Embase, Medline, and PsycINFO databases on the use of repetitive transcranial magnetic stimulation (rTMS) in healthy adults to modulate different subdomains (motor, temporal and reflection) of impulsivity. The results indicated that rTMS has distinct effects on different impulsivity subdomains. It has a significant, albeit small, effect on modulating motor impulsivity (g?=?0.30, 95% CI, 0.17 to 0.43, p?<?.001) and a moderate effect on temporal impulsivity (g?=?0.59, 95% CI, 0.32 to 0.86, p?<?.001). Subgroup analyses (e.g., excitatory vs. inhibitory rTMS, conventional rTMS vs. theta burst stimulation, analyses by stimulation sites, and type of outcome measure used) identified key parameters associated with the effects of rTMS on motor and temporal impulsivity. Age, sex, stimulation intensity and the number of pulses were not significant moderators for effects of rTMS on motor impulsivity. Due to lack of sufficient data to inform a meta-analysis, it has not been possible to assess the effects of rTMS on reflection impulsivity. The present findings provide preliminary evidence that rTMS can be used to modulate motor and temporal impulsivity in healthy individuals. Further studies are required to extend the use of rTMS to modulate impulsivity in those at most risk of engaging in harmful behaviour as a result of impulsivity, such as patients with offending histories and those with a history of self-harming behaviour.  相似文献

Recent research shows that co-speech gestures can influence gesturers’ thought. This line of research suggests that the influence of gestures is so strong, that it can wash out and reverse an effect of learning. We argue that these findings need a more robust and ecologically valid test, which we provide in this article. Our results support the claim that gestures not only reflect information in our mental representations, but can also influence gesturer's thought by adding action information to one's mental representation during problem solving (Tower of Hanoi). We show, however, that the effect of gestures on subsequent performance is not as strong as previously suggested. As opposed to what previous research indicates, gestures' facilitative effect through learning was not nullified by the potentially interfering effect on subsequent problem-solving performance of incompatible gestures. To conclude, using gestures during problem solving seems to provide more benefits than costs for task performance.  相似文献

Procrastination is a common problem among university students, with at least half of the population reporting great difficulties initiating or completing tasks and assignments. Procrastination can have a negative impact on course grades and the ability to achieve a university degree, but can also lead to psychological distress. Cognitive behavior therapy (CBT) is believed to reduce procrastination, but few studies have investigated its effectiveness in a regular clinical setting. The current study explored its effects using a pragmatic randomized controlled trial comparing treatment delivered during 8 weeks as self-guided CBT via the Internet (ICBT) or as group CBT. In total, 92 university students with severe procrastination were included in the study (registered as a clinical trial on Clinicaltrials.gov: NCT02112383). Outcome measures on procrastination, depression, anxiety, and well-being were distributed at pre- and posttreatment as well as 6-month follow-up. An outcome measure of procrastination was administered weekly. Linear mixed and fixed effects models were calculated, along with improvement and deterioration rates. The results showed large within-group effect sizes on procrastination, Cohen’s d of 1.29 for ICBT, 95% Confidence Interval (CI) [0.81, 1.74], and d of 1.24 for group CBT, 95% CI [0.76, 1.70], and small to moderate benefits for depression, anxiety, and well-being. In total, 33.7% were regarded as improved at posttreatment and 46.7% at follow-up. No differences between conditions were observed after the treatment period, however, participants in group CBT continued or maintained their improvement at follow-up, while participants in self-guided ICBT showed some signs of deterioration. The findings from the current study suggest that CBT might be an effective treatment for those struggling with severe procrastination, but that a group format may be better for some to sustain their benefits over time and that the clinical significance of the results need to be investigated further.  相似文献
