Applying optimal stimulation theory, the present study explored the development of sustained attention as a dynamic process. It examined the interaction of modality and temperament over time in children and adults. Second-grade children and college-aged adults performed auditory and visual vigilance tasks. Using the Carey temperament questionnaires (S. C. McDevitt & W. B. Carey, 1995), the authors classified participants according to temperament composites of reactivity and task orientation. In a preliminary study, tasks were equated across age and modality using d' matching procedures. In the main experiment, 48 children and 48 adults performed these calibrated tasks. The auditory task proved more difficult for both children and adults. Intermodal relations changed with age: Performance across modality was significantly correlated for children but not for adults. Although temperament did not significantly predict performance in adults, it did for children. The temperament effects observed in children--specifically in those with the composite of reactivity--occurred in connection with the auditory task and in a manner consistent with theoretical predictions derived from optimal stimulation theory. 相似文献

The present study develops a method to create task equivalency for children and adults in vigilance research. Experiment 1 employed the signal detection index of perceptual sensitivity (d’) to calibrate vigilance tasks for 32 children (ages 78) and 32 adults. The results of Experiment 1 suggest that task equivalency across groups can be attained, and a vigilance decrement was observed for children. In Experiment 2, the task parameter of event rate was manipulated across two vigils. Again, 32 children (ages 78) and 32 adults participated. The results suggest that a reverse event rate effect emerged for both children and adults. In addition, developmental differences in response to the event rate manipulation and with respect to the vigilance decrement emerged: Children benefited less from the manipulation and were more likely to demonstrate a vigilance decrement than were adults. No developmental differences emerged for the sensitivity decrement. The results are explained with reference to how task demands interact with participant arousal, and implications for development and for future research are discussed. 相似文献

Specification search problems refer to two important but under-addressed issues in testing for factorial invariance: how to select proper reference indicators and how to locate specific non-invariant parameters. In this study, we propose a two-step procedure to solve these issues. Step 1 is to identify a proper reference indicator using the Bayesian structural equation modeling approach. An item is selected if it is associated with the highest likelihood to be invariant across groups. Step 2 is to locate specific non-invariant parameters, given that a proper reference indicator has already been selected in Step 1. A series of simulation analyses show that the proposed method performs well under a variety of data conditions, and optimal performance is observed under conditions of large magnitude of non-invariance, low proportion of non-invariance, and large sample sizes. We also provide an empirical example to demonstrate the specific procedures to implement the proposed method in applied research. The importance and influences are discussed regarding the choices of informative priors with zero mean and small variances. Extensions and limitations are also pointed out. 相似文献

Supervision is a practice that is utilized by a variety of practitioners to hone their counseling skills. Genetic counselors have embraced the supervision process, and some seek out supervision in a group setting with peers. Researchers have described the structure and content of genetic counseling peer supervision groups, and provided evidence for the benefits of seeking peer supervision. This study aimed to describe the interpersonal aspects of one genetic counseling peer supervision group, including personality traits and group dynamics, and how those factors influenced our experiences within the group. We also describe how the process of evaluating these factors impacted us individually and collectively. There was consensus that the group was a safe and trusting one, which was united by similar goals and mutual respect. Members reported gaining insights about how their own personality functioned within the group milieu, and also how the group setting impacted them. Based on our experiences, we recommend that other peer supervision groups consider similar self-evaluations on a periodic basis, both to enhance group functioning and to allow for increased self-awareness and professional growth. 相似文献

Emotion dysregulation is thought to be critical to the development of negative psychological outcomes. Gross (1998b) conceptualized the timing of regulation strategies as key to this relationship, with response-focused strategies, such as expressive suppression, as less effective and more detrimental compared to antecedent-focused ones, such as cognitive reappraisal. In the current study, we examined the relationship between reappraisal and expressive suppression and measures of psychopathology, particularly for stress-related reactions, in both undergraduate and trauma-exposed community samples of women. Generally, expressive suppression was associated with higher, and reappraisal with lower, self-reported stress-related symptoms. In particular, expressive suppression was associated with PTSD, anxiety, and depression symptoms in the trauma-exposed community sample, with rumination partially mediating this association. Finally, based on factor analysis, expressive suppression and cognitive reappraisal appear to be independent constructs. Overall, expressive suppression, much more so than cognitive reappraisal, may play an important role in the experience of stress-related symptoms. Further, given their independence, there are potentially relevant clinical implications, as interventions that shift one of these emotion regulation strategies may not lead to changes in the other. 相似文献

A central question in adolescent reproductive health circles is how to effectively disseminate research to practitioners in
a way that supports them in using the most scientifically sound and effective programming. In 2002, the Division of Reproductive
Health at the Centers for Disease Control and Prevention (CDC) tackled this question by funding three national-level and five
state-level organizations focused on adolescent pregnancy prevention to promote the use of science-based programs and approaches.
Healthy Teen Network (HTN) and Education, Training and Research Associates (ETR), two national organizations, have partnered
under this CDC funding to implement an effective model for capacity building. This paper provides an overview of the approaches
used by HTN and ETR in capacity building using a seven-step process. We describe how we modified the Interactive Systems Framework
for Dissemination and Implementation (ISF) for science-based innovations to apply to capacity-building for adolescent reproductive
health (ARH) programs, and how we developed relevant, sustainable training and technical support. We conclude by reviewing
some of the results of this training, and discuss the future work that will likely continue to advance the science behind
effective dissemination of ARH research to practice. 相似文献

No previous research has tested whether the specific age-related deficit in learning face-name associations that has been identified using recall tasks also occurs for recognition memory measures. Young and older participants saw pictures of unfamiliar people with a name and an occupation for each person, and were tested on a matching (in Experiment 1) or multiple-choice (in Experiment 2) recognition memory test. For both recognition measures, the pattern of effects was the same as that obtained using a recall measure: More face-occupation associations were remembered than face-name associations, young adults remembered more associated information than older adults overall, and older adults had disproportionately poorer memory for face-name associations. Findings implicate age-related difficulty in forming and retrieving the association between the face and the name as the primary cause of obtained deficits in previous name learning studies.
