Two studies investigated the role of executive control in moderating the relationship between automatic stereotype activation and behavioral responses. Race bias in weapon identification was used to measure stereotyping, and a process dissociation procedure was used to measure automatic and controlled components of performance. In Experiment 1, the controlled component was shown to correlate with general attention control and race-specific motivations to control prejudice. Across multiple measures, automatic race bias was more likely to be expressed as behavioral discrimination among individuals with poor executive control. Experiment 2 found the same relationship between automatic and controlled components of behavior when predicting impressions of a Black individual. Executive control is discussed in the context of other control strategies in influential dual-process models of stereotyping. 相似文献

The factor analysis of repeated measures psychiatric data presents interesting challenges for researchers in terms of identifying the latent structure of an assessment instrument. Specifically, repeated measures contain both within and between individual sources of variance. Although a number of techniques exist for separating out these 2 sources of variance, all are problematic. Recently, researchers have proposed that exploratory multilevel factor analysis (MFA) be used to appropriately analyze the latent structure of repeated measures data. The chief objective of this report is to provide a didactic step-by-step guide on how MFA may be applied to psychiatric data. In the discussion, we describe difficulties associated with MFA and consider challenges in factor analyzing life event appraisals in psychiatric samples. 相似文献

The authors examined word skipping in reading in 2 experiments. In Experiment 1, skipping rates were higher for a preview of a predictable word than for a visually similar nonword, indicating there is full recognition in parafoveal vision. In Experiment 2, foveal load was manipulated by varying the frequency of the word preceding either a 3-letter target word or a misspelled preview. There was again a higher skipping rate for a correct preview and a lower skipping rate when there was a high foveal load, but there was no interaction, and the pattern of effects in fixation times was the same as in the skipping data. Experiment 2 also showed significant skipping of nonwords similar to the target word, indicating skipping based on partial information. 相似文献

Letter-by-letter acquired dyslexia (pure alexia) is assumed to be related to the serial encoding of letters, but the evidence for this assumption is somewhat indirect. Here, we demonstrate that the deficit is indeed due to serial encoding by comparing the performance of a letter-by-letter dyslexic reader with the performance of normal readers who were forced to read letter by letter; the data patterns are remarkably similar. 相似文献

Deliberate self-harm (DSH) is a strong predictor of suicide in schizophrenia. The aim of this review was to identify risk factors for DSH in schizophrenia. This systematic review of the international literature examined cohort and case-control studies of patients with schizophrenia or related diagnoses that reported DSH as an outcome. Studies were identified by searching electronic databases and reference lists, and by consulting international experts. Fourteen studies met the eligibility criteria. Of the 29 variables examined by two or more studies, five (past or recent suicidal ideation, previous DSH, past depressive episode, drug abuse or dependence, and higher mean number of psychiatric admissions) were associated with an increased risk of DSH, and one (unemployment) was associated with a reduced risk. Schizophrenic patients with these risk factors need careful follow-up and monitoring, with treatment of any associated comorbid depression or drug abuse. Large, prospective studies of DSH in schizophrenia are needed to further define risk factors and to build on the findings of this review. 相似文献

The present study examined the relationship between the predictability of words within a sentence and the availability of
parafoveal word length information, on when and where the eyes move in reading. Predictability influenced first-pass reading
times when parafoveal word length preview information was correct, but not when it was incorrect. Similarly, for saccades
launched from near the target word (wordn), predictability influenced the probability with which it was skipped only when the word length preview was correct. By contrast,
for saccades launched farther away from wordn, predictability influenced word skipping regardless of the parafoveal word length preview. Taken together, the data suggest
that parafoveal word length preview and predictability can act as a joint constraint on the decision of when and where to
move the eyes. 相似文献

Although ADHD and depression are common comorbidities in youth, few studies have examined this particular clinical presentation. To address method bias limitations of previous research, this study uses multiple informants to compare the academic, social, and clinical functioning of children with ADHD, children with ADHD and depression, and children without ADHD, all derived from a large community sample. High levels of comorbid depression are found in children with ADHD. Children withADHDand depression are more depressed and anxious than their non-depressed ADHDcounterparts but do not have more extreme levels of ADHD or aggression. The association between depression and ADHD does not appear to be epiphenomenal, that is, related to a shared association with anxiety or externalizing symptoms. Finally, children with ADHD and depression display more impairment in social and academic functioning compared to controls. Although social impairment is greater in children with ADHD and depression than in children with only ADHD, conduct problems are not. 相似文献

Internet addiction: a review of current assessment techniques and potential assessment questions. 总被引:15,自引:0,他引:15
Keith W Beard 《Cyberpsychology & behavior》2005,8(1):7-14
The concept of Internet addiction has been proposed as an explanation for uncontrollable and damaging use of the Internet. Symptoms of excessive Internet use have been compared to the criteria used to diagnose other addictions such as pathological gambling. Although criteria to diagnose this problem have been proposed, methods of assessing excessive Internet use are limited. A structured interview based on the criteria proposed by Beard and Wolf is proposed to aid in the assessment of "Internet addiction." This, in turn, could aid in the diagnosis and intervention of a client who enters treatment reporting difficulties with excessive Internet use. 相似文献
