Previous research with adolescents has reported a negative relationship between media violence and empathy. There are, however, two important conceptual issues in this earlier literature that deserve further research attention. First, studies often treat empathy as a one-dimensional construct while it consists of both an affective and cognitive component. Second, while aiming to measure empathy, several studies have measured sympathy instead. Driven by these concerns, this study was designed to investigate the longitudinal relationship between media violence, affective empathy, cognitive empathy, and sympathy. Using data from a two-wave panel study with 943 adolescents (10–14 years old), a cross-lagged model tested whether media violence exposure negatively influences empathy and sympathy (desensitization) or whether empathy and sympathy negatively influence media violence exposure (selection). Results were in line with desensitization. However, rather than showing that media violence leads to a decrease in empathy (which previous studies have shown), results indicate a decrease in sympathy instead. These findings provide clarification to existing work as well as offer methodological and practical implications.  相似文献

Naming novel objects with novel count nouns changes how the objects are drawn from memory, revealing that object categorisation induces reliance on orientation-independent visual representations during longer-term remembering, but not during short-term remembering. Serial position effects integrate this finding with a more established conceptualisation of short-term and longer-term visual remembering in which the former is identified as keeping an item in mind. Adults were shown a series of four novel objects in orientations in which they would not normally be drawn from memory. When not named ("Look at this object"), the objects were drawn in the orientations in which they had been seen. When named with a novel count noun (e.g., "Look at this dax"), the final object continued to be depicted in the orientation in which it had been seen, but all other objects were depicted in an unseen but preferred (canonical) orientation, even though participants could still remember the orientations in which they had been seen. Although orientation-dependent exemplar representations appear to be more accessible than orientation-independent generic representations during short-term remembering, the reverse is the case during longer-term remembering. How the theoretical framework emerging from these observations accommodates a broader body of evidence is discussed.  相似文献

Post-extinction exposure of rats to a sub-conditioning procedure can evoke conditioned fear, which may correspond to fear return and/or fear learning potentiation. The aim of the present study was to clarify this issue and examine the effects of tetanic stimulation of the hippocampus (HPC) and medial prefrontal cortex (mPFC), two brain regions implicated in post-extinction modulation of conditioned fear. Rats were initially submitted to five tone-shock pairings with either a 0.7-mA or 0.1-mA shock. Tone-evoked freezing was observed only with the higher shock intensity, indicating that the 0.1-mA shock corresponded to a sub-conditioning procedure. All conditioned rats underwent fear extinction with 20 tone-alone trials. When retrained with the sub-conditioning procedure, they displayed again tone-evoked freezing, except when the initial tone was unpaired or a new tone was paired with the 0.1-mA shock, demonstrating fear return rather than fear learning potentiation. We also found that HPC and mPFC tetanic stimulations, applied 24h after the sub-conditioning procedure, similarly reduced this fear return. However, mPFC inactivation abolished temporary HPC tetanus effect, whereas HPC inactivation did not interfere with mPFC tetanus effect. These data confirm our previous findings and reveal the nature of HPC-mPFC interactions in post-extinction modulation of conditioned fear.  相似文献

The aim of this study was to examine depression and anxiety disorders and their characteristic symptoms (anhedonia/low positive affect and anxious arousal, respectively), along with measures of state negative affect (NA) and Type D personality, in relation to cardiac surgery related morbidity. Patients awaiting elective coronary artery bypass graft surgery (n=158; 20.9% female; 11.4% concomitant valve surgery; age M=64.7, SD=10.6) underwent the structured MINI International Neuropsychiatric Interview to determine current affective disorders. Patients also completed the Mood and Anxiety Symptom Questionnaire and a measure of Type D personality traits. Postoperative cardiac morbidity was confirmed after surgery during the index hospitalization and included stroke,renal failure, ventilation>24 h, deep sternal wound infection, reoperation, arrhythmia and 30-day mortality at any location (n=59, 37.3% of total). After adjustment for age, recent myocardial infarction, heart failure, hypertension, urgency of surgery and time spent on cardiopulmonary bypass generalized anxiety disorder was associated with cardiac morbidity (odds ratio [OR]=3.26, 95% confidence interval [CI] 1.10-9.67, p=0.03). Adjusted analysis of personality traits revealed the NA component of Type D personality was associated with cardiac morbidity (OR=1.07, 95% CI 1.01-1.14, p=0.03). The Mood and Anxiety Symptom Questionnaire subscales were not associated with increased morbidity risk. Affective disorders, affective phenotypes, and personality traits were differentially associated with post-cardiac surgery morbidity outcomes independent of cardiac surgery morbidity risk factors. Concurrent investigation of depression and anxiety with respect to cardiac outcomes warrants further research.  相似文献

The Frost Multidimensional Perfectionism Scale (FMPS) is a widely used measure of perfectionism. Previous studies of the nature of the factors of the FMPS have resulted in mixed findings and have failed to identify a stable factor structure. This study investigated the factor structure of the FMPS using both exploratory and confirmatory factor analysis (CFA), addressing previous methodological limitations. Participants were 6,449 students from two Australian universities. Exploratory factor analysis suggested a five‐factor model and a reduction in variables from 35 to 29 (FMPS‐29). CFA demonstrated goodness of fit of the revised measure. We also compared our model with a number of existing measurement models of perfection and found the proposed model provided a superior fit for this university student population. Support was found for the two second‐order constructs commonly referred to as adaptive and maladaptive perfectionism, although there appears to be little benefit in using this model over the first‐order model. Implications of the findings are discussed.  相似文献

Several studies have demonstrated that as listeners hear sentences describing events in a scene, their eye movements anticipate upcoming linguistic items predicted by the unfolding relationship between scene and sentence. While this may reflect active prediction based on structural or contextual expectations, the influence of local thematic priming between words has not been fully examined. In Experiment 1, we presented verbs (e.g., arrest) in active (Subject–Verb–Object) sentences with displays containing verb-related patients (e.g., crook) and agents (e.g., policeman). We examined patient and agent fixations following the verb, after the agent role had been filled by another entity, but prior to bottom-up specification of the object. Participants were nearly as likely to fixate agents “anticipatorily” as patients, even though the agent role was already filled. However, the patient advantage suggested simultaneous influences of both local priming and active prediction. In Experiment 2, using passive sentences (Object–Verb–Subject), we found stronger, but still graded influences of role prediction when more time elapsed between verb and target, and more syntactic cues were available. We interpret anticipatory fixations as emerging from constraint-based processes that involve both non-predictive thematic priming and active prediction.  相似文献

We examined the prospective associations between family socio-economic background, childhood intelligence (g) at age 11, educational and occupational attainment, and social attitudes at age 33 in a large (N = 8804), representative sample of the British population born in 1958. Structural equation Modeling identified a latent trait of ‘liberal social attitudes’ underlying attitude factors that are antiracist, socially liberal, and in support of gender equality. Another attitude factor—‘political trust’—was relatively independent from the latent attitude trait and has somewhat different pathways in relation to the other variables included in the analysis. There was a direct association between higher g at age 11 and more liberal social attitudes and political trust at age 33. For both men and women the association between g and liberal social attitudes was partly mediated via educational qualifications, and to a much lesser extent via adult occupational attainment. For women the association between g and political trust was partly mediated through both educational qualification and occupational attainment, and for men it was mediated mainly via occupational attainment. Men and women who had higher educational qualifications and higher occupational status tend to be more socially liberal and more trusting of the democratic political system. In terms of socio-economic background, people from less privileged families showed less political trust, but did not differ much in liberal social attitudes from those born into relatively more privileged circumstances. This study shows that social background, cognitive ability, education, and own social status influence perceptions of society.  相似文献

Chronic fatigue syndrome (CFS) is a poorly understood illness that is characterized by profound and prolonged exhaustion and has no clear pathological marker. This study investigated the role of illness severity and secondary beliefs in depression among a CFS cohort, using the A–B–C framework of Rational Emotive Behavioral Therapy. Empirical research has consistently found that CFS patients tend to hold more negative cognitions about their illness, which could be associated with greater severity and emotional deficits. Specifically, secondary beliefs were explored as a mediating factor; as evidence suggests that secondary beliefs can result in dysfunctional emotions and/or behaviors, such as depression. Furthermore, it is estimated that up to 80% of CFS patients concurrently have depression. There were 156 participants with CFS who completed a questionnaire pack, which included the revised version of the Illness Perception Questionnaire, the Secondary Beliefs Scale (SBS), and the Cardiac Depression Scale. Hierarchical regression analysis revealed that secondary beliefs mediated the relationship between illness severity and depression. Specifically, the approval and comfort subscales of the SBS were significantly associated with depression. The current findings indicated that secondary beliefs could be an important focus in treatment of depression in chronic illness. As the mediating role of secondary beliefs is a new research finding, it is advised that further exploratory research is required.  相似文献

Previous research has shown that emotional stimuli interfere with ongoing activities. One explanation is that these stimuli draw attention away from the primary task and thereby hamper the correct execution of the task. Another explanation is that emotional stimuli cause a temporary freezing of all ongoing activity. We used a go/ no-go task to differentiate between these accounts. According to the attention account, emotional distractors should impair performance on both go and no-go trials. According to the freezing account, the presentation of emotional stimuli should be detrimental to performance on go trials, but beneficial for performance on no-go trials. Our findings confirm the former prediction: Pictures high in emotional arousal impaired performance on no-go trials.  相似文献
