Measuring consciousness: task accuracy and awareness as sigmoid functions of stimulus duration

When consciousness is examined using subjective ratings, the extent to which processing is conscious or unconscious is often estimated by calculating task performance at the subjective threshold or by calculating the correlation between accuracy and awareness. However, both these methods have certain limitations. In the present article, we propose describing task accuracy and awareness as functions of stimulus intensity (thus obtaining an accuracy and an awareness curve) as suggested by Koch and Preuschoff (2007). The estimated lag between the curves describes how much stimulus intensity must increase for awareness to change proportionally as much as accuracy and the slopes of the curves are used to assess how fast accuracy and awareness increases and whether awareness is dichotomous. The method is successfully employed to assess consciousness characteristics on data from four different awareness scales.     

形而上学的原初“制作”——西方哲学诞生的技术现象学考察

探讨形而上学的原初制作,意味着要从技艺的角度去追问原初形而上学的构造。本文拟从语言技艺的技术现象学视域,来尝试探索从柏拉图到亚里士多德之原初形而上学制作的隐秘。一、原初形而上学与语言技艺一般认为,形而上学的形成以巴门尼德的存在学说为其开端,中经苏格拉底-柏拉图的理念论,在亚里士多德的形而上学中初步完成。(张志伟等,第16页)这个观点并非没有争议。譬如,     

Multisensory enhancement of attentional capture in visual search

Multisensory integration increases the salience of sensory events and, therefore, possibly also their ability to capture attention in visual search. This was investigated in two experiments where spatially uninformative color change cues preceded visual search arrays with color-defined targets. Tones were presented synchronously with these cues on half of all trials. Spatial-cuing effects indicative of cue-triggered capture of attention were larger on tone-present than on tone-absent trials, demonstrating multisensory enhancements of attentional capture. Larger capture effects for audiovisual events were found when cues were color singletons, and also when they appeared among heterogeneous color distractors. Tone-induced increases of attentional capture were independent of color-specific top-down task sets, suggesting that this multisensory effect is a stimulus-driven bottom-up phenomenon.     

1980-2009年国内眼动研究的文献计量分析

对收录在中国期刊网和中国优秀博硕士学位论文全文数据库中的370篇眼动研究文献(1980—2009年)进行计量学分析,结果表明:(1)国内眼动研究从2003年起呈现快速增长趋势;(2)以阅读方面的实证研究为主,主要以大学生为研究对象,以中文阅读材料和图片为研究材料,以Eyelink-Ⅱ和ASL-504眼动仪为研究工具,重点关注眼动指标和阅读指标;(3)天津师范大学是国内眼动研究的重要力量;(4)成果发表以心理学期刊为主,其中《心理科学》发表最多;(5)合作研究已成为眼动研究的主要形式,但核心作者群尚未形成;(6)大多数眼动研究受到各类项目资助。     

国外军事心理学研究现状分析

为了解国外军事心理学研究的动态和研究领域,本文对1980年至2009年国际军事测量学会（IMTA）发表的论文进行了系统分析。结果显示,军人心理选拔等七个领域的文献数量占总数的85.7%;在近30年的文献中,关键词训练与教育、工作绩效、选拔、工作分析等出现频率最高,超过文献总数的58.0%;在近10年的文献中,关键词选拔、领导力、工作分析、工作绩效、离职和人因素等前8项出现频率最高,合计达70.2%。军人心理选拔、军事领导和组织行为、军事临床心理等方面越来越受到军事心理学研究者的重视。     

Urban African-American Girls’ Participation and Future Intentions Toward Physical Education

Despite the fact that physical education holds great promise for the promotion of public health, urban African American girls’ interest and participation in physical education tends to decline with age. Using the Theory of Planned Behavior and feminist poststructuralist theory, this study was designed to examine African American girls’ physical education participation and possible social, cognitive, and motivational factors that drive them away from future intentions toward physical education. Participants were 168 African American girls (age range?=?14–17?years, mean age?=?14.7?years) enrolled in three public high schools from a large urban inner-city school district in the Midwestern United States. Both quantitative and word-data were collected. Results revealed that participation in physical education played an important role in urban African-American girls’ overall physical activity engagement. However, unfavorable attitudes and lack of perceived support impeded their intentions toward future enrollment in physical education. Major factors related to their intentions were: anticipated short- and long-term outcomes, body image concerns, the influence of their mothers, and scheduling conflicts. The findings indicate opportunities for early intervention.     

The Importance of Therapist/Client Ethnic/Racial Matching in Couples Treatment for Domestic Violence

Outcome research indicates a relative degree of variability regarding the effectiveness of client and therapist ethnic/racial matching (see Cabral and Smith 2011; Shin et al. in J Couns Psychol 52(1):45–56, 2005). Considering these findings, our study hopes to further understand the complexity behind ethnic/racial matching in treatment. In this study, we examined interviews with clients and therapists regarding ethnic/racial matching in couples treatment for domestic violence (e.g., McCollum and Stith in Violence Vict 23(2):187–201, 2008). Our findings indicated that ethnic/racial matching is a complex multi-faceted issue and connected ethnic/racial matching with issues of culture, human experience, and others. We recommend clinicians consider the complexity of ethnic/racial matching in practice.
