正负性情绪的自主神经反应及应用

情绪可以唤醒自主神经系统, 伴随有一系列的生理变化。从基础研究的角度来看, 正负性情绪可以诱发心血管系统(如心率、血压、心率变异性)、皮肤电系统(如皮肤电导水平)、呼吸系统(如呼吸阻力、每分通气量)和其他系统(如瞳孔直径、胃肌电等)的活动及其变化。在应用研究方面, 正负性情绪诱发的自主神经反应可以应用在多个领域, 主要包括用户体验中的情绪测量、基于生理信号的人-机情感交互系统的开发, 以及消费者态度和偏好的测查等。对于现有研究结果中存在的分歧, 从被试的个体差异、诱导范式的不一致性和诱导效果的可靠性, 以及刺激材料属性的多样化等方面进行了分析, 指出了未来研究应该注意的问题。     

音乐训练延缓言语感知老龄化

听力正常的老年人常常受到噪声环境中言语感知能力下降的困扰。延缓这一类型的听觉老龄化具有重要的心理和社会意义。经历过音乐训练的老年人在噪声环境中的言语识别成绩显著高于听力相当但是未经历过音乐训练的老年人。此外, 音乐训练也伴随着老年人的听觉脑干对言语信号的加工速度和时间精度的明显提高。这一言语信号神经表征的增强可能在音乐训练延缓老年人言语感知能力下降的过程中发挥了重要作用。     

Effects of visual information on adults' and infants' auditory statistical learning

Infant and adult learners are able to identify word boundaries in fluent speech using statistical information. Similarly, learners are able to use statistical information to identify word-object associations. Successful language learning requires both feats. In this series of experiments, we presented adults and infants with audio-visual input from which it was possible to identify both word boundaries and word-object relations. Adult learners were able to identify both kinds of statistical relations from the same input. Moreover, their learning was actually facilitated by the presence of two simultaneously present relations. Eight-month-old infants, however, do not appear to benefit from the presence of regular relations between words and objects. Adults, like 8-month-olds, did not benefit from regular audio-visual correspondences when they were tested with tones, rather than linguistic input. These differences in learning outcomes across age and input suggest that both developmental and stimulus-based constraints affect statistical learning.     

目标或背景:联合搜索知觉学习的内容

采用颜色-形状联合搜索任务探讨短期特征联结知觉学习的效果和机制。训练被试在由不同颜色和形状组合的字母干扰子中搜索具有特定颜色和形状的目标字母,训练时间约为40分钟。通过训练,被试搜索特定的颜色-形状联结的目标字母的能力有所提升,并且学习效应能够迁移至背景改变目标不变的条件中,但是不能迁移至背景不变目标改变的条件中。这一结果提示,被试在进行短期联合搜索知觉学习时,学习到的是目标,而并非背景或目标与背景的联系。     

CONSISTENT VISUAL ANALYSES OF INTRASUBJECT DATA

Visual inspection of single‐case data is the primary method of interpretation of the effects of an independent variable on a dependent variable in applied behavior analysis. The purpose of the current study was to replicate and extend the results of DeProspero and Cohen (1979) by reexamining the consistency of visual analysis across raters. We recruited members of the board of editors and associate editors for the Journal of Applied Behavior Analysis to judge graphs on a 100‐point scale of experimental control and by providing a dichotomous response (i.e., “yes” or “no” for experimental control). Results showed high interrater agreement across the three types of graphs, suggesting that visual inspection can lead to consistent interpretation of single‐case data among well‐trained raters.     

Encouraging electricity savings in a university residential hall through a combination of feedback, visual prompts, and incentives

This experiment investigated the combined use of visual prompts, daily feedback, and rewards to reduce electricity consumption in a university residential hall. After a 17-day baseline period, the experimental intervention was introduced in the intervention hall, and no change was made in the control hall. Energy usage decreased in the intervention hall, but energy usage did not change appreciably in the control hall. In the intervention hall, mean daytime and nighttime savings were 16.2% and 10.7%, respectively, compared to savings of 3.8% (day) and 6.5% (night) in the control hall.     

Les compétences des enseignants du technique au lycée professionnel

Vocational school teachers face a problem of acceptance. On arrival in a school, they find themselves put under pressure by families, students, the educational establishment and businesses. This paper deals with the gaps and ambiguities that exist between the educational, vocational and professional areas of teaching. In particular, it shows how, during training, teachers refer to their professional experience in order to connect the two areas, and to centre their activities on student training. The gap between professional experience and the pedagogic framework acts as a motor for training and can be seen as an attempt to gain acceptance. It brings into question the views of training and vocationnal psychologist counsellors (COP) in an analysis of vocational counselling related to whether students complete their diploma course or drop out of school.     

高中生学校生活中的情感体验:基于日重现法的研究

采用日重现法对133名高中生学校生活中的情感体验进行实描研究,考察了高中生在学校生活中的活动、活动场所、互动对象及与之相应的各种情感体验的日波动模式。结果如下:(1)高中生在一天中的绝大多数活动、场所以及人际互动中均表现为积极情感的体验强度大于消极情感;(2)大部分积极情感以及疲劳的体验强度都表现为在晚睡前达到一天中的最高点,大部分消极情感体验都在该时段降至一天中的最低点;(3)全天都体验到较强烈的胜任感,中午的体验强度最大,早晨的体验强度最低。     

受艾滋病影响儿童的歧视知觉在歧视经历和心理健康之间的作用分析

本研究旨在考察中国农村地区受艾滋病影响儿童(包括双孤儿童、单孤儿童和非孤儿童)在经历了父母感染艾滋病、父母因为艾滋病丧亡后的歧视经历和歧视知觉状况,及其对心理健康的影响.采用问卷调查了1221名被试,测查了他们的歧视经历、歧视知觉、心理健康(抑郁、孤独、自尊).经过数据分析发现:(1)歧视经历和歧视知觉存在显著的年龄段和儿童类别的差异,12岁及以下的儿童得分显著高于13岁及以上的,双孤儿童得分显著高于单孤儿童和非孤儿童;抑郁、孤独和自尊存在显著的儿童类别差异,双孤儿童、单孤儿童差于非孤儿童;且孤独和自尊还存在显著的年龄段差异,12岁以下的儿童差于13岁以上的;(2)不同歧视经历和歧视知觉的儿童在抑郁、孤独和自尊上存在显著差异,均是歧视经历、歧视知觉多的儿童抑郁和孤独严重、自尊低;(3)歧视经历对抑郁、孤独和自尊都有显著的预测作用,歧视知觉在其中起到了部分中介作用.     

掩蔽启动范式中的负相容效应——知觉阶段的交互还是反应阶段的抑制

掩蔽启动范式中, 当掩蔽刺激与目标刺激的时间间隔达到100~200ms时, 出现负相容效应。负相容效应是指相容条件的反应时大于不相容条件, 错误率高于不相容条件。目前主要有三种理论来解释负相容效应的发生机制, 分别是自我抑制理论、目标更新理论和掩蔽抑制理论。三种理论探讨了负相容效应发生的机制, 即负相容效应发生在知觉阶段还是反应阶段, 涉及自我引发抑制还是刺激引发抑制。有关负相容效应发生的机制还需进一步的探讨。
