儿童理解监控的即时加工过程

理解监控在口语和阅读信息的交流中起关键作用。即时加工研究为揭示儿童理解监控发展特点及内在机制提供了新途径。本文结合已有口语理解监控和阅读理解监控成果,对儿童理解监控的特点及其可能的影响因素进行了全面综述。未来研究应在儿童理解监控的时间进程、口语理解监控及理论模型等方面进一步深化,积极开展脑机制研究,并从视听跨通道整合角度探索儿童理解监控过程的发展。     

Réalité virtuelle et santé des personnes âgées institutionnalisées. Vers un EHPAD 2.0 ?

Virtual reality (VR) is used in general health care: prevention, physical medicine, chronic and acute pain, quality of life in palliative care, and in psychiatry: anxiety, depression, addiction, psychosis. Our objective is showing VR using among elderly people in French retirement home. Virtual reality is showing efficacy as distraction, anti-pain, tranquillising, antidepressant methods. It should be an answer to many elderly health problems. VR is easy to use, with low side effects. Non-drug treatments among elderly people are recommended. Used as complementary or alternative medicine, VR must be shaped for using with old and fragile people in retirement home.     

Physical effort biases the perceived pleasantness of neutral faces: A virtual reality study

The role of affective responses to effort in the regulation of physical activity behavior is widely accepted. Yet, to investigate these affective responses during physical activity, most studies used direct self-reported measures that are prone to biases (e.g., social desirability, ability to introspect). To reduce these biases, we used an indirect measure (i.e., an affect misattribution procedure) that assessed the implicit affective valence elicited by physical effort in 42 healthy young adults. Specifically, participants rated the pleasantness of neutral human faces presented in a virtual environment while cycling at different intensities. We used this rating as an indicator of implicit affective valence. Results showed that higher perceived effort was associated with lower pleasantness ratings of neutral faces, with this effect only emerging at moderate-to-high levels of perceived effort. Further analyses showed that higher actual effort was also associated with lower pleasantness ratings of neutral faces. Overall, these findings suggest that higher levels of perceived effort are associated with decreased affective valence during physical activity. Finally, this study presents a new indirect measure of affective valence during physical activity.     

三维动静态场景下返回抑制的扩散

使用虚拟现实技术探讨三维动静态空间下返回抑制是否敏感于深度线索及返回抑制效应是否存在空间扩散。采用线索−靶子范式,分别设置三维静态和动态场景。结果发现：三维静态场景,不同深度及不同侧位置均发生返回抑制且产生效应大小有差异;三维动态场景,不同线索条件反应时无显著差异。结果表明,三维静态场景下,返回抑制敏感于深度线索,其效应在空间中存在扩散;客体运动破坏了返回抑制的产生及其效应的空间扩散。     

A/B型人格对时间性前瞻记忆的影响

通过对比A/B两种人格者在执行即无社会关系特征又无个人重要性的时间性前瞻记忆任务时的时间性前瞻记忆成绩和在执行时间性前瞻记忆过程中的时间监控模式,发现A/B型人格的背景任务成绩和TBPM任务成绩都没有显著差异,而时间监视模式有显著差异。说明A型人格被试能更高效的利用认知资源,以更高效和更策略的时间监控模式完成TBPM任务。也说明TBPM是一类与时间监控能力密切相关的前瞻记忆类型。     

记忆源检测的加工分离

同一个记忆源检测任务是否可以依赖两种不同的加工——无意识启发式加工和有意识系统式加工,是源检测加工机制研究探索的一个重要问题。本研究拟借助加工分离程序来分离同一个源检测任务中的启发式和系统式加工,并进一步考察了启发式和系统式加工受刺激呈现时间的影响。结果发现:位置源检测任务依赖于启发式和系统式两种加工,且随着刺激呈现时间的增长,系统式加工的贡献显著地提高,启发式加工的贡献却无显著提升。这一结果既验证了记忆源检测的双加工机制,也暗示了两种加工在加工深度上的差异。

Generalization of posture training to computer workstations in an applied setting

Improving employees' posture may decrease the risk of musculoskeletal disorders. The current paper is a systematic replication and extension of Sigurdsson and Austin (2008), who found that an intervention consisting of information, real-time feedback, and self-monitoring improved participant posture at mock workstations. In the current study, participants worked in an applied setting, and posture data were collected at participants' own workstations and a mock workstation. Intervention in the mock setting was associated with consistent improvement in safe posture at the mock workstation, but generalization to the actual workstation was limited.     

The efficiency of behavior rating scales to assess inattentive-overactive and oppositional-defiant behaviors: applying generalizability theory to streamline assessment

Although the efficiency with which a wide range of behavioral data can be obtained makes behavior rating scales particularly attractive tools for the purposes of screening and evaluation, feasibility concerns arise in the context of formative assessment. Specifically, informant load, or the amount of time informants are asked to contribute to the assessment process, likely has a negative impact on the quality of data over time and the informant's willingness to participate. Two important determinants of informant load in progress monitoring are the length of the rating scale (i.e., the number of items) and how frequently informants are asked to provide ratings (i.e., the number of occasions). The purpose of the current study was to investigate the dependability of the IOWA Conners Teacher Rating Scale (Loney & Milich, 1982), which is used to differentiate inattentive-overactive from oppositional-defiant behaviors. Specifically, the facets of items and occasions were examined to identify combinations of these sources of error necessary to reach an acceptable level of dependability for both absolute and relative decisions. Results from D studies elucidated a variety of possible item-occasion combinations reaching the criteria for adequate dependability. Recommendations for research and practice are discussed.     

What factors influence prospective memory for elderly people in a naturalistic setting?1

Previous studies comparing prospective memory between the elderly and young adults have shown that elderly adults perform better in naturalistic settings, while young adults perform better in laboratory settings. The purpose of this study was to examine what factors influence prospective memory in naturalistic settings, and we specifically focused on age, the complexity of the prospective memory task, self‐evaluation and knowledge of memory function, retrospective memory, external memory aids, and internal memory strategies as potential influential factors. Eighty‐six healthy, elderly participants were enrolled (44 women and 42 men, mean age = 68.56 years, SD = 4.53). The results showed that the use of external memory aids increased in complex prospective memory tasks that depended on output monitoring, while other factors did not influence prospective memory performance. These results suggest that elderly adults can perform tasks adequately by using external memory aids that compensate for age‐related memory declines in naturalistic settings.
