INDUSTRIAL SAFETY HAZARD REDUCTION THROUGH PERFORMANCE FEEDBACK

A “feedback package” system, designed to prevent occupational accidents and to fit directly into the normal operations of an industrial organization, was analyzed. Eighteen hazardous conditions in six production departments were assessed during seven observation sessions over a 12-week period, plus four follow-up observations over 4 months. The “feedback package” was presented in multiple baseline fashion, across subjects (department supervisors). It consisted of presenting the supervisor with copies of observational data, accompanied by a note which congratulated good practices and suggested ways for improving safety conditions, along with occasional comments from a senior executive. The results indicated that during the feedback phase, hazard rates were lower and less variable than during the baseline phase. Baseline data were highly variable with peaks ranging from 20 to 55 hazards per department. Following intervention, hazard frequencies dropped by 60%, averaged across departments, with decreases ranging from 29% to 88%. During treatment, data stabilized, with the highest frequency reaching 33. A modified feedback system was implemented by the organization following termination of the study, validating the assumption that such a system would tend to maintain.     

Perceptual organization of line configurations: Is visual awareness necessary?

We examined whether configuring, which determines the appearance of grouped elements as a global shape, requires visual awareness, using a priming paradigm and two invisibility-inducing methods, CFS and sandwich masking. The primes were organized into configurations based on closure, collinearity, and symmetry (collinear primes), or on closure and symmetry (noncollinear primes). The prime-target congruency could be in configuration or in elements. During CFS, no significant response-priming was observed for invisible primes. When masking induced invisibility, a significant configuration response-priming was found for collinear and noncollinear primes, visible and invisible, with larger magnitude for the former. An element response-priming of equal magnitude was evident for visible and invisible noncollinear primes. Our results suggest that configuring can be accomplished in the absence of visual awareness when stimuli are rendered invisible by sandwich masking, but it benefits from visual awareness. Our results also suggest sensitivity to the available grouping cues in unconscious processing.     

中文阅读中副中央凹区域文本信息加工时程的眼动研究

副中央凹文本对阅读有非常重要的作用,考察读者在注视何时起对其加工有助于解决阅读中词汇加工方式的理论问题,当前研究结果存在很大争论。本研究采用消失文本范式,操纵词n-1和n+1的呈现时间(0m/40ms),考察读者加工两侧副中央凹信息的时程。结果发现,相比0ms,在注视早期40ms内,词n+1的呈现能够显著促进阅读加工,而词n-1未对阅读产生影响,表明右侧副中央凹信息的加工发生在注视早期,而左侧则未发生在该早期阶段。结果支持阅读眼动控制的并列加工模型。     

字体大小和呈现位置对多媒体课件文字理解的影响

本研究通过多媒体教室现场实验和实验室实验,以判断成语的感情色彩为测试任务,探讨字体大小和位置对多媒体课件文字理解的影响。结果表明,字体尺寸大于0．26°视角时,位于多媒体教室不同座位区域的被试都能较好地理解多媒体课件呈现的文字内容,而文字呈现位置对多媒体课件文字理解的影响较小。

组织中的社会阻抑:概念界定、影响结果和形成机制

社会阻抑是指长期的、蓄意地妨碍个体积极人际关系的建立和维持,影响个体在工作上的成功及良好名誉的行为.文章在介绍社会阻抑概念和测量的基础上,综述了社会阻抑在心理健康、自我效能感等个人层面和组织氛围层面的消极影响;接着阐明了个体对社会阻抑行为的实施和反应一方面受到人格、认知等内在因素的影响,另一方面也受到社会情境、社会支持等外在因素的影响.未来研究需进一步加强对社会阻抑概念、测量、研究方法、影响因素等方面的深入探讨.     

Intellectual property protection,technological innovation and enterprise value—An empirical study on panel data of 80 advanced manufacturing SMEs

Study the role of intellectual property protection in advanced manufacturing SMEs. Is it to protect the growth of advanced manufacturing SMEs, or to inhibit the growth of SMEs in advanced manufacturing? the paper brings the medium variable – technological innovation to explore acting paths of intellectual property protection in enterprises’ value improvement. Through analysis of panel data of 80 SMEs of advanced manufacture collected during the period from 2013 to 2015, Research results show that as for SMEs of advanced manufacture, the inverted-U relationship still exists in the influences brought by intellectual property protection to enterprise values. Meanwhile, U-shaped relations exist between intellectual property protection and technological innovation. Increase of technological innovation investment can promote increase of enterprise values.     

Does prism adaptation affect visual search in spatial neglect patients: A systematic review

Prism adaptation (PA) is a widely used intervention for (visuo‐)spatial neglect. PA‐induced improvements can be assessed by visual search tasks. It remains unclear which outcome measures are the most sensitive for the effects of PA in neglect. In this review, we aimed to evaluate PA effects on visual search measures. A systematic literature search was completed regarding PA intervention studies focusing on patients with neglect using visual search tasks. Information about study content and effectiveness was extracted. Out of 403 identified studies, 30 met the inclusion criteria. The quality of the studies was evaluated: Rankings were moderate‐to‐high for 7, and low for 23 studies. As feature search was only performed by five studies, low‐to‐moderate ranking, we were limited in drawing firm conclusions about the PA effect on feature search. All moderate‐to‐high‐ranking studies investigated cancellation by measuring only omissions or hits. These studies found an overall improvement after PA. Measuring perseverations and total task duration provides more specific information about visual search. The two (low ranking) studies that measured this found an improvement after PA on perseverations and duration (while accuracy improved for one study and remained the same for the other). This review suggests there is an overall effect of PA on visual search, although complex visual search tasks and specific visual search measures are lacking. Suggestions for search measures that give insight in subcomponents of visual search are provided for future studies, such as perseverations, search path intersections, search consistency and using a speed–accuracy trade‐off.
