Although personality tests are widely used to select applicants for a variety of jobs, there is concern that such measures are fakable. One procedure used to minimize faking has been to disguise the true intent of personality tests by randomizing items such that items measuring similar constructs are dispersed throughout the test. In this study, we examined if item placement does influence the fakability and psychometric properties of a personality measure. Study participants responded to 1 of 2 formats (random vs. grouped items) of a personality test honestly and also under instructions to fake or to behave like an applicant. Results indicate that the grouped item placement format was more fakable for the Neuroticism and Conscientiousness scales. The test with items randomly placed fit the data better within the honest and applicant conditions. These findings demonstrate that the issue of item placement should be seriously considered before administering personality measures because different item presentations may affect the incidence of faking and the psychometric properties of the measure. 相似文献

Attentional control in the aging brain: insights from an fMRI study of the stroop task 总被引:18,自引:0,他引:18

Several recent studies of aging and cognition have attributed decreases in the efficiency of working memory processes to possible declines in attentional control, the mechanism(s) by which the brain attempts to limit its processing to that of task-relevant information. Here we used fMRI measures of neural activity during performance of the color-word Stroop task to compare the neural substrates of attentional control in younger (ages: 21-27 years old) and older participants (ages: 60-75 years old) during conditions of both increased competition (incongruent and congruent neutral) and increased conflict (incongruent and congruent neutral). We found evidence of age-related decreases in the responsiveness of structures thought to support attentional control (e.g., dorsolateral prefrontal and parietal cortices), suggesting possible impairments in the implementation of attentional control in older participants. Consistent with this notion, older participants exhibited more extensive activation of ventral visual processing regions (i.e., temporal cortex) and anterior inferior prefrontal cortices, reflecting a decreased ability to inhibit the processing of task-irrelevant information. Also, the anterior cingulate cortex, a region involved in evaluatory processes at the level of response (e.g., detecting potential for error), showed age-related increases in its sensitivity to the presence of competing color information. These findings are discussed in terms of newly emerging models of attentional control in the human brain. 相似文献

In order to understand how emotional aspects evolve and are related to craving for alcohol, different emotion-related variables were examined in relationship to craving during a protracted withdrawal. To this end state affectivity (PANAS), emotional intelligence (EI) (TEIQue), and craving (OCDS) were assessed at the onset (T1: day 1 or 2) and at the end (T2: day 14 to 18) of three-week protracted withdrawal among alcohol-dependent inpatients (DSM-IV, N = 41). A significant decrease in craving and negative affectivity (NA) was observed from T1 to T2 while EI scores remained low. At both baseline and follow-up, there was a significant moderation effect of EI on the link between NA and craving for alcohol. Negative mood at the onset of the cure was linked to craving at the end of the withdrawal period but only among patients with low trait EI scores. The merits of using psychotherapeutic approaches were discussed in the treatment of alcohol addiction. 相似文献

Previous dual-task research pairing complex visual tasks involving non-spatial cognitive processes during dichotic listening have shown effects on the late component (Ndl) of the negative difference selective attention waveform but no effects on the early (Nde) response suggesting that the Ndl, but not the Nde, is affected by non-spatial processing in a dual-task. Thus to further explore the nature of this dissociation and whether the Nd waveform is affected by spatial processing; fourteen adult participants performed auditory dichotic listening in conjunction with visuo-spatial memory in a cross-modal dual-task paradigm. The results showed that the visuo-spatial memory task decreased both the Nde and Ndl waveforms, and also attenuated P300 and increased its latency. This pattern of results suggests that: (1) the Nde reflects a memory trace that is shared with vision when the information is spatial in nature, and (2) P300 latency appears to be influenced by the discriminability of stimuli underlying the Nde and Ndl memory trace. 相似文献

We encounter many faces each day but relatively few are personally familiar. Once faces are familiar, they evoke semantic and social information known about the person. Neuroimaging studies demonstrate differential brain activity to familiar and non-familiar faces; however, brain responses related to personally familiar faces have been more rarely studied. We examined brain activity with fMRI in adults in response to faces of their mothers and fathers compared to faces of celebrities and strangers. Overall, faces of mothers elicited more activity in core and extended brain regions associated with face processing, compared to fathers, celebrity or stranger faces. Fathers’ faces elicited activity in the caudate, a deep brain structure associated with feelings of love. These new findings of differential brain responses elicited by faces of mothers and fathers are consistent with psychological research on attachment, evident even during adulthood. 相似文献

The current study investigated the patterns of aggressive behavior displayed in a sample of 282 students in the 4th through
7th grades (M age = 11.28; SD = 1.82). Using cluster analyses, two distinct patterns of physical aggression emerged for both
boys and girls with one aggressive cluster showing mild levels of reactive aggression and one group showing high levels of
both reactive and proactive aggression. Both aggressive clusters showed problems with anger dysregulation, impulsivity, thrill
and adventure seeking, positive outcome expectancies for aggression, and higher rates of bullying. However, the combined cluster
was most severe on all of these variables and only the combined aggressive group differed from non-aggressive students on
their level of callous-unemotional traits. Similar patterns of findings emerged for relational aggression but only for girls. 相似文献

Two multi-level studies were conducted to examine the effects of attitudes towards coworkers on daily well-being. Study 1 linked daily levels of coworker satisfaction to job satisfaction and life satisfaction and examined the extent to which job satisfaction mediated the relationship between coworker satisfaction and life satisfaction among 33 government employees. Study 2 replicated and extended Study 1 by examining the extent to which agreeableness moderated the relationships between daily levels of coworker satisfaction and job and life satisfaction among an occupationally diverse sample of 79 employees. Results revealed that coworker satisfaction varied significantly from day to day and was positively related to job and life satisfaction. Further, job satisfaction partially mediated the relationship between daily coworker satisfaction and life satisfaction. Finally, agreeableness moderated the relationship between coworker satisfaction and job and life satisfaction, such that daily levels of these variables were more contingent on coworker satisfaction for agreeable individuals. 相似文献

A previous study by Pollatsek et al. ( 1993 ) claims that the perceptual span in reading is restricted to the fixated line, i.e. readers typically focus their visual attention on the line of text being read. The present study investigated whether readers make use of content structure signals (paragraph indentations and topic headings) present several lines away from the currently fixated line. We reasoned that as these signals are low-resolution visual objects (as opposed to letter and word identity), readers may attend to them even if they are located some distance away from the fixated line. Participants read a hierarchically organized multi-topic expository text containing structure signals in either a normal condition or a window condition, where the text disappeared above and below a vertical 3° gaze-contingent region. After reading, participants were asked to produce a written recall of the text. The results showed that the overall reading rate was not affected by the window. Nevertheless, the headings were reread more in the normal condition than in the window one. In addition, more topics were recalled in the normal than in the window condition. We interpret the results as indicating that the readers visually attend to useful text layout features while considering bigger units than single text lines. The perception of topic headings located away from the fixated line may favour long-range regressions towards them, which in turn may favour text comprehension. This claim is consistent with previous studies that showed that look-back fixations to headings are performed with an integrative intent. 相似文献
