Nursery school and second-grade subjects were trained on an optional intradimensional/extradimensional shift task with (1) no overtraining, (2) overtraining on the initial problem only, (3) overtraining on the shift problem only, or (4) overtraining on both the initial and the shift problems. Predictions concerning the effects of age and training conditions on the type of solution and the breadth of learning for the shift problem were derived from selective attention theory. However, the results were not consistent with the one-look assumption of such models. Instead, a multiple-look theory in which the breadth of attention varies with task demands seems most tenable. 相似文献

Alcohol and marijuana produce significant dose-related reductions in dynamic visual acuity. Ten subjects participated in a double-blind experiment involving three dose levels of each drug (including placebo). The reduction of DVA produced by alcohol (1.0 ml 95% ethanol/kg body weight) was greater than for marijuana (15 mg Δ-9-tetrahydrocannabinol), and we suggest that this difference was produced by differential oculomotor effects of the two drugs. We have speculated that reduction in DVA under alcohol may be a contributing factor in alcohol-related traffic accidents. 相似文献

This study involved respirometric measurements of six normals and six stutterers throughout vocal and whispered readings of 12 CVC words. In each condition, dependent variables were peak air flow rates on initial and final consonants, flow duration and flow volume between peaks. The stutterers, both individually and as a group, were almost completely fluent during the readings in both conditions. At the same time, their air flow, duration and volume scores either equalled or exceeded those of the controls. These results are discussed in terms of how air flow and durational features of articulation contribute to fluent speech. Directions for future work are also described. 相似文献

Multidimensional item response theory (MIRT) models for response style (e.g., Bolt, Lu, & Kim, 2014, Psychological Methods, 19, 528; Falk & Cai, 2016, Psychological Methods, 21, 328) provide flexibility in accommodating various response styles, but often present difficulty in isolating the effects of response style(s) from the intended substantive trait(s). In the presence of such measurement limitations, we consider several ways in which MIRT models are nevertheless useful in lending insight into how response styles may interfere with measurement for a given test instrument. Such a study can also inform whether alternative design considerations (e.g., anchoring vignettes, self-report items of heterogeneous content) that seek to control for response style effects may be helpful. We illustrate several aspects of an MIRT approach using real and simulated analyses. 相似文献

AbstractStudies have shown that children share both positive and dark spiritual experiences. The former dominates the literature but whilst the need to address the dark side of spirituality has been raised it has not, as yet, been dealt with as widely as the more positive aspects. This paper draws on an empirical study with 44 children aged 8–11 who were interviewed in school after visiting a sacred space. Three key themes arising from their conversations are covered in this paper: divine encounter; physical feelings and fear. It is argued that the most appropriate way of understanding these phenomena is to draw on different fields and disciplines, notably although not exclusively, theology, psychoanalysis, psychology and neuroscience. The paper concludes that it is important to recognise both the light and dark and the blurred boundaries between them, in addition to different ways of perceiving them, in order to understand the whole child. 相似文献

Background
Medical tourism, the practice of persons intentionally travelling across international boundaries to access medical care, has drawn increasing attention from researchers, particularly in relation to potential ethical concerns of this practice. Researchers have expressed concern for potential negative impacts to individual safety, public health within both countries of origin for medical tourists and destination countries, and global health equity. However, these ethical concerns are not discussed within the sources of information commonly provided to medical tourists, and as such, medical tourists may not be aware of these concerns when engaging in medical tourism. This paper describes the methodology utilized to develop an information sheet intended to be disseminated to Canadian medical tourists to encourage contemplation and further public discussion of the ethical concerns in medical tourism.Methods
The methodology for developing the information sheet drew on an iterative process to consider stakeholder feedback on the content and use of the information sheet as it might inform prospective medical tourists’ decision making. This methodology includes a literature review as well as formative research with Canadian public health professionals and former medical tourists.Results
The final information sheet underwent numerous revisions throughout the formative research process according to feedback from medical tourism stakeholders. These revisions focused primarily on making the information sheet concise with points that encourage individuals considering travelling for medical tourism to do further research regarding their safety both within the destination country, while travelling, and once returning to Canada, and the potential impacts of their trip on third parties. This methodology may be replicated for the development of information sheets intending to communicate ethical concerns of other practices to providers or consumers of a certain service.110.
When leaders are not who they appear: The effects of leader disclosure of a concealable stigma on follower reactions 下载免费PDF全文
Two studies examined follower reactions to disclosure of concealable stigma (i.e., transgender identity) by a leader. Using 109 employed participants, Study 1 showed followers rated leaders disclosing a stigma less likable and effective. This effect was both direct and indirect through relational identification with the leader. Using 206 employed participants, Study 2 found when a leader's stigma was involuntarily found out and disclosed later they received lower ratings of likability and effectiveness compared to leaders who voluntarily came out and disclosed earlier. Method (found out vs. came out) and timing of disclosure (later vs. earlier) had direct relationships with ratings of likability and effectiveness and method of disclosure had an indirect relationship with the outcomes via relational identification. 相似文献
