Recent acts of violence have demonstrated the impact of violent ideological groups worldwide. However, the systematic study of these groups is somewhat limited. The Internet is a valuable tool for investigating ideological group behavior because it is easily accessible and commonly used by these groups. This study attempted to extend previous research by examining online message boards to assess processes particular to ideological group membership. A content analysis was conducted on several group process variables using 29 groups with message boards. A Kruskal‐Wallis test with follow‐up pairwise comparisons was used to find that violent ideological groups differed from nonviolent ideological and nonviolent nonideological groups on 7 group process variables and 3 content variables. Implications are discussed.  相似文献

Little research has been conducted on the psychometrics of the very short scale (36 items) of the Children's Behavior Questionnaire, and no one-item temperament scale has been tested for use in applied work. In this study, 237 United States caregivers completed a survey to define their child's behavioral patterns (i.e., Surgency, Negative Affectivity Effortful Control) using both scales. Psychometrics of the 36-item Children's Behavior Questionnaire were examined using classical test theory, principal factor analysis, and item response modeling. Classical test theory analysis demonstrated adequate internal consistency and factor analysis confirmed a three-factor structure. Potential improvements to the measure were identified using item response modeling. A one-item (three response categories) temperament scale was validated against the three temperament factors of the 36-item scale. The temperament response categories correlated with the temperament factors of the 36-item scale, as expected. The one-item temperament scale may be applicable for clinical use.  相似文献

Individuals?? goals can direct their own social behavior and development. We extended and validated a social dating goals measure (SDGS-R) to assess identity, intimacy and status goals, and compared goals by age, gender, sexual orientation and romantic status. Participants were 121 adolescents and 249 emerging adults (age M?=?20.6). The expected 3-factor structure of the SDGS-R was found and confirmed (18 items). Identity, intimacy and status goals had small correlations with each other and analyses validated the meaning and uniqueness of each goal. Participants reported more identity and intimacy goals than status goals. Intimacy goals were more prominent among older compared to teenage participants and those with a partner rather than without one. Females reported more identity dating goals than males. There was no difference in the goals of same-sex and other-sex attracted youth. The availability of the SDGS-R will allow further study of romantic development and relationship functioning.  相似文献

The disruptive impact of task-extraneous air-traffic radio speech on a task involving the serial-recall of combined verbal and spatial stimuli (7 letters and their locations) that were broadly analogous to information about aircraft callsigns and movements was examined. Regardless of the dimension to be recalled (identity or spatial location), accuracy was significantly disrupted by the air-traffic speech. Prior knowledge as to which dimension to recall did not affect accuracy and did not interact with the disruptive effect of air-traffic speech, but did extend the time to initiate a response to the first item. The results are discussed with reference to theories of the irrelevant sound effect and stimulus-dimension binding in short-term memory. The vulnerability of cognitive processing related to air-traffic management and similar work environments is also discussed.  相似文献

Cognitive control mechanisms-such as inhibition-decrease the likelihood that goal-directed activity is ceded to irrelevant events. Here, we use the action of auditory distraction to show how retrieval from episodic long-term memory is affected by competitor inhibition. Typically, a sequence of to-be-ignored spoken distracters drawn from the same semantic category as a list of visually presented to-be-recalled items impairs free recall performance. In line with competitor inhibition theory (Anderson, 2003), free recall was worse for items on a probe trial if they were a repeat of distracter items presented during the previous, prime, trial (Experiment 1). This effect was produced only when the distracters were dominant members of the same category as the to-be-recalled items on the prime. For prime trials in which distracters were low-dominant members of the to-be-remembered item category or were unrelated to that category-and hence not strong competitors for retrieval-positive priming was found (Experiments 2 and 3). These results are discussed in terms of inhibitory approaches to negative priming and memory retrieval. (PsycINFO Database Record (c) 2012 APA, all rights reserved).  相似文献

Experimental studies show that training people to attend to negative stimuli makes them more likely to respond with greater anxiety to stress. The present study investigated this effect in students using measures of cardiovascular responses to stress and examined whether individual differences influence the impact of attention training on stress responses. Using a standard dot probe task, 30 participants underwent negative attentional bias training and 34 participants underwent anti-negative training before completing a stressful speech task. Results indicated that, overall, participants exhibited acclimatization to the procedures (indicated by a dip in blood pressure post-training) and normal stress responding (indicated by elevated blood pressure in response to stress; p<.001). However, consideration of participants' scores for neuroticism/emotional-stability revealed important differences in how the intervention impacted on cardiovascular profiles (p=.008). For participants with high neuroticism scores, the negative attentional bias intervention elicited more exaggerated stress responding than the anti-negative intervention. For those with low neuroticism scores (i.e., emotionally stable participants), the anti-negative intervention was associated with elevated post-intervention blood pressure and higher blood pressure reactivity to stress. These findings provide evidence of the impact of attentional bias manipulation on physiological stress reactivity and suggest the effect is highly contingent on individual temperaments.  相似文献

Family history of cancer is critical for identifying and managing patients at risk for cancer. However, the quality of family history data is dependent on the accuracy of patient self reporting. Therefore, the validity of family history reporting is crucial to the quality of clinical care. A retrospective review of family history data collected at a community hospital between 2005 and 2009 was performed in 43,257 women presenting for screening mammography. Reported numbers of breast, colon, prostate, lung, and ovarian cancer were compared in maternal relatives vs. paternal relatives and in first vs. second degree relatives. Significant reporting differences were found between maternal and paternal family history of cancer, in addition to degree of relative. The number of paternal family histories of cancer was significantly lower than that of maternal family histories of cancer. Similarly, the percentage of grandparents' family histories of cancer was significantly lower than the percentage of parents' family histories of cancer. This trend was found in all cancers except prostate cancer. Self-reported family history in the community setting is often influenced by both bloodline of the cancer history and the degree of relative affected. This is evident by the underreporting of paternal family histories of cancer, and also, though to a lesser extent, by degree. These discrepancies in reporting family history of cancer imply we need to take more care in collecting accurate family histories and also in the clinical management of individuals in relation to hereditary risk.  相似文献

Psychological distress in rheumatoid arthritis (RA) is associated with adverse clinical outcomes, and appears highly related to patients' illness perceptions. This study aimed to investigate the association between illness perceptions, psychological distress, positive outlook and physical outcomes in RA. Two hundred and thirty patients aged >18 years and prescribed at least one disease-modifying anti-rheumatic drug (DMARD) were recruited from outpatient clinics across Hertfordshire (England). Patients completed a questionnaire that assessed psychological distress and positive outlook (depression, anxiety and positive outlook scale), illness perceptions (IPQ-R) and functional disability (health assessment questionnaire). Information regarding prescribed medication and disease activity [disease activity score (DAS28)] was collected from medical notes. Psychological distress, but not positive outlook, was associated with functional disability and DAS28. After controlling for sex, age and DAS28, perceptions of greater symptomatology (identity) and lesser understanding of RA (coherence) were significantly associated with increased psychological distress. Perceptions of greater treatment control were associated with greater positive outlook, but only for those with low DAS28. Coherence was also associated with positive outlook. These findings indicate that illness perceptions may influence psychological distress and positive outlook in RA patients, and may therefore be a useful basis for future psychological interventions.  相似文献
