Distance perception across spatial discontinuities

We investigated the use of nested contact relations in perceiving the relative distance of locations on discontinuous surfaces. Observers viewed computer-generated displays under monocular static conditions and adjusted a marker to match the perceived distance of a cube. The marker and cube were raised above the ground by two different platforms separated by a gap. The relative heights and distances of the platforms were varied. We found the following: (1) When spatially discontinuous surfaces are coplanar, locations of objects resting on these surfaces appear to be compared directly, bypassing relations with the underlying ground plane. (2) Spatial displacement between the platforms produces a bias, in the direction of the displacement, in the perceived relative locations of objects resting on the platforms. This suggests that local spatial relations between objects and their platforms are only partially integrated with more global spatial relations between the discontinuous surfaces of the platforms.     

Distance perception mediated through nested contact relations among surfaces

In complex natural scenes, objects at different spatial locations can usually be related to each other through nested contact relations among adjoining surfaces. Our research asks how well human observers, under monocular static viewing conditions, are able to utilize this information in distance perception. We present computer-generated naturalistic scenes of a cube resting on a platform, which is in turn resting on the ground. Observers adjust the location of a marker on the ground to equal the perceived distance of the cube. We find that (1) perceived distance of the cube varies appropriately as the perceived location of contact between the platform and the ground varies; (2) variability increases systematically as the relating surfaces move apart; and (3) certain local edge alignments allow precise propagation of distance information. These results demonstrate considerable efficiency in the mediation of distance perception through nested contact relations among surfaces.     

Entrevista con el professor Johannes C. Brengelmann

RESUMEN

Johannes C. Brengelmann dirige la sección de Psicología del instituto Max-Planck de Munich y es ampliamente conocido en España por su influencia directa o indirecta sobre algunos de los psicólogos que más han contribuido a la extensión de las técnicas de Modificación de Conducta en España. Tanto desde una perspectiva institucional como desde un punto de vista científico, su aportación al desarrollo de los procedimientos conductuales en Europa ha sido decisiva. En esta entrevista, el profesor Brengelmann, se refiere a las influencias recibidas en su formación, sus intereses actuales en la psicología clínica y medicina comportamental y la organización del trabajo en la sección de psicología del Instituto Max-Planck de psiquiatría. También evalúa críticamente el desarrollo de las terapias cognitivas y valora el desarrollo de la psicología española en el contexto de la Europea.     

2008 Revision of the Chinese Code of Ethical Use of Psychological Tests and Its Implementation Status

In response to the rapidly increasing application and abuse of psychological tests in China, the Psychometrics Division of the Chinese Psychological Society published the 2008 revisions of the Chinese Code of Ethical Use of Psychological Tests. We investigated the implementation status of the code 2½ years after its promulgation. Sample included 284 psychological professionals and psychology graduate students. The average accuracy rate for the appropriate use of psychological tests was 67.1% (range = 25.5–97.5%), with 10 items having accuracy rates below 45%. Participants remained uncertain about the clients' rights to information about the purpose, psychometric properties, and scores of the tests. The most frequent violations involved “using psychological tests without psychometric information for entertainment purposes” and “using SCL-90 to measure mental health of normal people.”     

阅读过程中的注视位置效应

注视位置效应是指在阅读过程中,读者的眼跳往往定位于一个单词的特定位置。探讨影响读者注视位置的因素,是当前阅读过程中眼动控制的基本问题之一。文章对不同语言文字系统中注视位置效应的最新进展进行综述,主要内容包括：（1）阅读拼音文字时的注视位置效应,包括阅读有词间空格的拼音文字时的注视位置效应,特别是单词的词长、词间空格、词频和预测性对注视位置的影响以及该效应出现的年龄特征与个体差异等,以及阅读泰语和日语时的注视位置效应;（2）阅读中文时的注视位置效应。最后,文章指出了未来中文阅读中注视位置效应研究尚需解决的几个问题。     

双语词汇理解切换中非目标语言加工

实验采用直接语音掩蔽启动范式,通过掩蔽词的有、无呈现对切换后单词的读音判断反应时产生影响,进而了解非熟练双语者双语理解切换中非目标语言加工状态。实验结果表明,无呈现掩蔽词组的反应时比有呈现组的判断反应时长;不同掩蔽词呈现时间两组中切换反应时判断不显著。实验证明无论是哪一种语言作为非目标语言,其在词汇层上均都不会被激活;双语词汇理解切换中,切换至熟练语言比切换至不熟练语言切换代价小。     

创伤后应激障碍诊治的思考

创伤后应激障碍随着人类灾害事故的频发升级,已引起了世界范围内的高度关注和研究.本文就思考缘起、疾病发病态势、疾病临床表现、其生物学变化及疾病预后所引发的思考启示、提醒当前要加强公众教育,并从中体悟疾病所映射的医学、物理学、心理学、社会学、宗教、哲学方面的涵义做一探索.     

整合医学再探

整合医学就是将医学各领域最先进的知识理论和临床各专科最有效的实践经验分别加以有机整合,并根据社会、环境、心理的现实,以人体全身状况为根本,进行修整、调整,使之成为更加符合、更加适合人体健康和疾病治疗的新的医学体系.整,即整理的整,是方法,是手段,是过程;合,即适合的合,是要求,是标准,是结果.     

The relationship between learning goal orientation,goal setting,and performance: a longitudinal study

In an educational setting, we examined the relationship of learning goal orientation with goal setting and performance over time. At the first time point, we assessed levels of trait learning goal orientation and asked participants to set performance goals. At each follow‐up time point, we reported to participants their current course grade and allowed them to revise their goals. Learning goal orientation was associated with both setting higher goals and maintaining higher performance over time. Additionally, the relationship of learning goal orientation and performance was found to be mediated by goal setting.     

Asian Couples in Negotiation: A Mixed‐Method Observational Study of Cultural Variations Across Five Asian Regions

The purpose of this study was to explore variations in how contemporary couples from five different Asian regions negotiate disagreements. Video recordings of 50 couples (10 each from Japan, Korea, Mainland China, Taiwan, and Hong Kong) discussing unresolved disagreements provided raw data for quantitative and qualitative analyses. First, teams of coders from each region used a common protocol to make quantitative ratings of content themes and interaction patterns for couples from their own region. An interregional panel of investigators then performed in‐depth qualitative reviews for half of these cases, noting cultural differences not only in observed patterns of couple behavior but also in their own perceptions of these patterns. Both quantitative and qualitative analyses revealed clear regional differences on dimensions such as overt negativity, demand‐withdraw interaction, and collaboration. The qualitative results also provided a richer, more nuanced view of other (e.g., gender‐linked) conflict management patterns that the quantitative analyses did not capture. Inconsistencies between qualitative and quantitative data and between the qualitative observations of investigators from different regions were most pronounced for couples from Korea and Japan, whose conflict styles were subtler and less direct than those of couples from the other regions.
