The role of eye fixations in concentration and amplification effects during multiple object tracking
When tracking spatially extended objects in a multiple object tracking task, attention is preferentially directed to the centres of those objects (attentional concentration), and this effect becomes more pronounced as object length increases (attentional amplification). However, it is unclear whether these effects depend on differences in attentional allocation or differences in eye fixations. We addressed this question by measuring eye fixations in a dual-task paradigm that required participants to track spatially extended objects, while simultaneously detecting probes that appeared at the centres or near the endpoints of objects. Consistent with previous research, we observed concentration and amplification effects: Probes at the centres of objects were detected more readily than those near their endpoints, and this difference increased with object length. Critically, attentional concentration was observed when probes were equated for distance from fixation during free viewing, and concentration and amplification were observed without eye movements during strict fixation. We conclude that these effects reflect the prioritization of covert attention to particular spatial regions within extended objects, and we discuss the role of eye fixations during multiple object tracking. 相似文献

Although past research has demonstrated a link between personality and job performance, potential enabling factors of this relationship have yet to be explored comprehensively. We hypothesized that perceptions of work climate, specifically relationship dimensions—cohesion, supervisor support, and job involvement—might be the mechanism through which the relationship between personality and job performance can be explained. Two hundred and thirty Australian employees completed an online survey measuring personality, relationship dimensions of work climate (job involvement, coworker cohesion, and supervisor support) and job performance. Results revealed that the relationship dimensions of work climate fully mediated the relationship between agreeableness and job performance, and extraversion and job performance, while the relationship between neuroticism and job performance was partially mediated by relationship dimensions of work climate. Supervisor support primarily accounted for this mediated effect for the neuroticism–job performance relationship, whereas for extraversion only job involvement explained significant unique variance. Our findings suggest that the relationship of agreeableness, extraversion, and neuroticism with job performance is indirect, and perceptions of the work environment itself play a role in this relationship. This implies that organizations should consider the work environment, in addition to personality during selection procedures. Future research should examine whether different levels of work environment dimensions, foster greater job performance in employees. 相似文献

Senior pastors at churches affiliated with the Baptist General Convention of Texas (BGCT) were anonymously surveyed using an online questionnaire to ascertain their knowledge and perceptions of the causes and potential treatments of mental illness. BGCT senior pastors reported a moderate level of contact with the mentally ill and populations known to have higher than average rates of mental illness (e.g., homeless). They also reported that the individuals with whom they counsel are rarely diagnosed with mental illness. While Baptist senior pastors embraced biological causes and treatments for mental illness as most important and effective, they varied greatly across disorders as to the perceived contribution of psychosocial and spiritual factors. Senior pastors in the present study reported being open to referring their congregants to mental health care professionals with whom they shared common values. Overall, the results of the study point to a need for greater mental health education for Baptist clergy as well as opportunities for the development of increased collaboration between the mental health and faith communities. 相似文献

Older adults are often more susceptible to various illusions and distortions of memory than young adults. In the experiments reported here, we explored the question of whether normal aging was associated with a larger revelation effect, an illusion of memory in which items that are revealed gradually during a recognition test are more likely to be called old than unrevealed items that are shown in their entirety. Contrary to expectations, older adults were not susceptible to this memory illusion. A revelation effect occurred for young but not older adults, even when older adults were similar to young adults on measures of recognition and repetition priming. When data across experiments were combined, there was evidence for a negative revelation effect in older adults in which revealed items were less likely called old than unrevealed items. These results place boundary conditions on the claim that older adults are more susceptible than young adults to memory illusions, and imply that one or more mechanisms underlying the revelation effect are age sensitive. 相似文献

The purpose of the present investigation was to compare and contrast sport and business leaders' perceptions regarding what makes for a successful organization. Twenty sport ( N = 10) and business ( N = 10) leaders were interviewed and asked about their perceptions of organizational effectiveness in the area of group dynamics including (a) leadership, (b) group cohesion, and (c) communication. Using qualitative methods, results revealed more similarities than differences, with most sport and business leaders in agreement on the factors relating to organizational success. Specifically, all higher- and lower-order themes were identified by leaders in both areas, the emphasis simply being a matter of degree. Some of the more notable differences included business leaders putting more emphasis on being honest and being a reflective listener, whereas sport leaders emphasize interactions with others and having positive reinforcement in their communications. These similarities and differences are discussed in terms of the extant literature, and future directions for research are offered, such as investigating how to specifically enhance the transfer of skills and principles between sport and business settings. 相似文献

A number of empirical investigations indicate that tests with a greater number of response options tend to yield better psychometric performance. We hypothesized that a version of the MMPI–2 with a polytomous response format would outperform the standard dichotomous format in terms of observed score reliability and validity. Two versions of the MMPI–2 RC scales were administered consecutively in counterbalanced order to 199 undergraduate students attending a large Midwestern university: the standard true–false version, and an experimental version containing 4 response options (very true, mainly true, slightly true, and false, not at all true). After participants completed both versions, 2 scales from the Multidimensional Personality Questionnaire (MPQ) were administered to assess differences in convergent validity. Results showed enhancements in reliability for all RC scale scores and increases in the convergent validity of scores. Directions for further investigation and potential implications for future test development are discussed. 相似文献

Studies on the psychometric properties of the EAS Temperament Survey (EAS) have produced equivocal results. In particular the psychometrics of the EAS are largely unknown in adolescence. Confirmatory factor analysis was used to explore the EAS structure in adolescents. Structural equation modeling was also used to assess measurement invariance and factor stability. A modified 4-factor model provided the best fit to the data and demonstrated reasonable longitudinal invariance and stability. Furthermore, the standardized factor scores correlated at near unity with the sum of observed scores, suggesting factor interpretations remained unchanged. However, the modifications suggest that further work is necessary. 相似文献
