Purpose
The purpose of this study was to investigate relationships between dimensions of work ethic and dimensions of organizational citizenship behavior (OCB) and counterproductive work behavior (CWB).Design/Methodology/Approach
Data were collected from employed individuals in MBA and undergraduate management courses and their work supervisors (N = 233). Participants represented diverse occupations with respect to job levels and industries. Participants completed the work ethic inventory, and participants’ managers completed ratings of OCB and CWB.Findings
The work ethic dimension of centrality of work was positively related to both dimensions of OCB (i.e., OCB-I and OCB-O), and the work ethic dimension of morality/ethics was negatively related to one of the dimensions of CWB (i.e., CWB-I).Implications
Modern perspectives on job performance recognize the multidimensional nature of the domain (i.e., the expanded criterion domain). In addition, noncognitive predictors such as work ethic have value as individual differences that are associated with performance outcomes. The assessment of such constructs can help inform selection and placement activities where a focus on OCB and CWB is important to managers.Originality/Value
This study provides additional evidence on the relationship between work ethic and performance outcomes. Previous research has provided limited information on the relationship between dimensions of work ethic and dimensions of OCB, and no information existed on the relationship between work ethic dimensions and CWB.942.

Bias in spatial memory: a categorical endorsement 总被引:2,自引:0,他引:2
Two experiments investigated how angular estimates reflect bias as a function of response mode, geometric plane of variation, number of implicit categories, memory load and intervening task conditions. In Experiment 1, participants made motor and verbal estimates of incline and azimuth from memory. Estimates in both response modes showed signs of bias predicted by a single-category adaptation of Huttenlocher et al. [Huttenlocher, J., Hedges, L. V., & Duncan, S. (1991). Categories and particulars: Prototype effects in estimating spatial location. Psychological Review, 98, 352-376] category-adjustment model. In Experiment 2, participants made motor estimates of azimuth from memory under a variety of conditions. Stimuli in this experiment were distributed along two contiguous spatial categories. Although increasing levels of cognitive load did not produce a graded effect, participants' estimates were biased and were well described by a multiple-category adaptation of the category-adjustment model. Results from both studies supported an implicit region-based model of bias in spatial memory. These findings were discussed with respect to accounts of spatial memory that propose multiple systems or formats for coding. 相似文献

This study examined Ogbu's widely accepted thesis that African American students reject high academic achievement because they perceive its limited utility in a world where their upward mobility is constrained by racial discrimination. Boykin's psychosocial integrity model contends that Black students value high achievement but that discrepancies between their formative cultural experiences and those imposed in school lead them to reject the modes of achievement available in classrooms. Ninety Black children completed a measure of attitudes toward students who achieve via mainstream or African American cultural values. Participants rejected the mainstream achievers and embraced the African American cultural achievers. Moreover, they expected their teachers to embrace the mainstream achievers and reject those who achieved through high-verve behavior. Results suggest that Boykin's thesis is a needed refinement to Ogbu's ideas. They indicate that Black children may reject not high achievement but some of the mainstream cultural values and behaviors on which success in mainstream classrooms is made contingent. 相似文献

The identification of reliable and valid means for evaluating the effectiveness of school-based treatments and completing
diagnostic evaluations of middle school aged students are needed. The present study examined the inter-rater agreement of
teacher ratings and the relationship between ratings and observational data in a middle school setting. The data are interpreted
in the context of differences between a secondary and elementary school setting. Teacher ratings and observational data were
collected regularly over the course of two academic years for middle school students diagnosed with ADHD. The results indicate
low rates of inter-rater agreement as well as low rates of agreement between teachers and observational data, and between
observational data collected in different classrooms. Inter-rater agreement was lowest in late fall and gradually increased
over the second half of the year. Implications for conducting treatment outcome evaluations of school-based treatment programs
and diagnostic evaluations are discussed. 相似文献

Medications with dopamine antagonist properties, such as haloperidol, and those with serotonin reuptake inhibitor properties, such as clomipramine, have been shown to improve fluency. To examine the degree to which each of these two pharmacological mechanisms might independently affect fluency, a selective serotonin reuptake inhibitor, paroxetine, and a selective dopamine (D-2) antagonist, pimozide, were evaluated. Both types of medications also affect mood and anxiety, factors that could influence fluency levels. Therefore, we also evaluated the medications’ effects on generalized and speech-related anxiety and the relationships between changes in anxiety and changes in fluency in 11 subjects with a history of developmental stuttering. The randomized, double blind, placebo-controlled crossover study that was designed had to be terminated prior to completion due to severe side effects following withdrawal from paroxetine. Even with a reduced sample size (n = 6), significant improvement in percent fluent speaking time (p = 0.02) was found using a telephone task between baseline and pimozide (n = 6), with average duration of dysfluencies significantly shorter (p = 0.04) but no significant difference in the estimated number of dysfluencies per minute. This significant improvement was associated with non-significant increases in generalized anxiety, but non-significant decreases in speech-related anxiety. No significant differences were found in fluency between baseline and paroxetine (n = 5). These preliminary results suggest that fluency improvement is more likely to be mediated by dopaminergic rather than serotonergic mechanisms. Due to its side effects, however, pimozide may be considered a risk for treatment of stuttering.
Educational objectives: As a result of reading this paper the reader will describe and explain: (1) how medications may affect fluency and the rationale for selecting medications for treatment trials; (2) the interrelationship between fluency and anxiety; and (3) factors important in developing clinical trials using medications. 相似文献

To investigate the reliability and validity of the Yale Global Tic Severity Scale (YGTSS), 28 youth aged 6 to 17 years with Tourette's syndrome (TS) participated in the study. Data included clinician reports of tics and obsessive-compulsive disorder (OCD) severity, parent reports of tics, internalizing and externalizing problems, and child reports of depression and anxiety. All children participated in a 2nd YGTSS administration by the same rater 48 days later. Good internal consistency and stability were found for the YGTSS scores. YGTSS scores demonstrated strong correlations with parent-rated tic severity (r = .58-.68). YGTSS scores were not significantly related to measures of clinician ratings of OCD severity (r = .01-.15), parent ratings of externalizing and internalizing behavior (r = -.07-.20), and child ratings of depression (r = .02-.26) and anxiety (r = -.06 -.28). Findings suggest that the YGTSS is a reliable and valid instrument for the assessment of pediatric TS. 相似文献

Recent studies on the epidemiology of obsessive-compulsive disorder (OCD) estimate 50 million patients suffer from OCD worldwide, thus making it a global problem. The treatment of OCD has changed substantially over the last 2 decades following the introduction of selective serotonin reuptake inhibitors, which provide symptom improvement in approximately 60% of patients. However, some patients remain resistant to the standard pharmacologic and behavioral treatments. Although some treatment-resistant patients respond to pharmacologic augmentations, others do not, and there is evidence that some of the most severe cases benefit from treatment with neurosurgical interventions. Besides pharmacologic, behavioral, and neurosurgical approaches, different brain stimulation methods-transcranial magnetic stimulation, deep brain stimulation, and electroconvulsive therapy-have been investigated in treatment-resistant patients with OCD. However, available data about the use of these techniques in OCD treatment are quite limited in terms of sample size and study design, given the difficulty in conducting standard blinded trials for these procedures. In addition, none of the mentioned treatments have received Food and Drug Administration approval for the treatment of OCD. Nevertheless, promising findings regarding efficacy, tolerability, and non-invasiveness and/or reversibility of these techniques have increased interest in investigating their use in treatment-resistant OCD. 相似文献

Alcohol research in Alaska Native communities has a contentious history. This project has attempted to address a critical need for research to guide alcohol abuse prevention and treatment with Alaska Natives using culturally anchored participatory action research. The process of grounding the research methodology in the culture and community is described, along with its contribution to community psychology's understanding of the importance of cultural factors. Tensions between indigenous values and ways of knowing, and Western research methodologies are delineated, along with how these tensions were resolved. Important issues that arose in doing culturally anchored participatory action research are described. These included the development of a community of inquiry, key methodological decisions, the empowerment of participants as coresearchers, and flexibility in research implementation. 相似文献
