The centroid paradigm: Quantifying feature-based attention in terms of attention filters

This paper elaborates a recent conceptualization of feature-based attention in terms of attention filters (Drew et al., Journal of Vision, 10(10:20), 1–16, 2010) into a general purpose centroid-estimation paradigm for studying feature-based attention. An attention filter is a brain process, initiated by a participant in the context of a task requiring feature-based attention, which operates broadly across space to modulate the relative effectiveness with which different features in the retinal input influence performance. This paper describes an empirical method for quantitatively measuring attention filters. The method uses a “statistical summary representation” (SSR) task in which the participant strives to mouse-click the centroid of a briefly flashed cloud composed of items of different types (e.g., dots of different luminances or sizes), weighting some types of items more strongly than others. In different attention conditions, the target weights for different item types in the centroid task are varied. The actual weights exerted on the participant’s responses by different item types in any given attention condition are derived by simple linear regression. Because, on each trial, the centroid paradigm obtains information about the relative effectiveness of all the features in the display, both target and distractor features, and because the participant’s response is a continuous variable in each of two dimensions (versus a simple binary choice as in most previous paradigms), it is remarkably powerful. The number of trials required to estimate an attention filter is an order of magnitude fewer than the number required to investigate much simpler concepts in typical psychophysical attention paradigms.     

团体心理咨询对提高大学生自信心的效果研究

本研究探讨了团体心理咨询在提高大学生自信心方面的作用。我们精心设计了团体心理咨询活动的过程,并在活动前后用五种量表对团体成员进行了测量。通过分析量表测量结果及其他定性研究方法,我们发现：（１）团体心理咨询可以有效地提高大学生的自信心。（２）团体心理咨询在发展性目标上也是有效的。本研究结果对今后的团体心理咨询研究及其应用具有一定的参考价值。     

先天性红-绿色觉异常者的非彩色表色色差辨别研究

该文就先天性红－绿色觉异常者对非彩色系表色色差的辨别展开了研究。结果表明,先天性红－绿色觉异常者色差识别的量值△Ｅ随目视评价的等级不同而异;先天性红－绿色觉异常者与色党正常者在非彩色表色辨别上存在一定的差异;同一明度等级上、下限的变化对先天性红－绿色觉异常者的非彩色表色辨别存在影响,这种影响与明度的级别有关。     

助推戒烟的行为干预策略

烟草危害是人类所面临的重大公共健康挑战之一。传统的控烟策略主要依赖健康宣教、烟草税和控烟条例等手段,但是较少考虑到吸烟行为的“非理性因素”及其心理机制,因此仍不能有效帮助吸烟者成功戒烟。行为科学的发展为助推吸烟者成功戒烟提供了新视角。以实施主体和干预的影响机制为划分标准,可将助推戒烟的行为干预策略分为由政府和公共健康服务部门执行的情境型干预策略和认知型干预策略以及吸烟者可自主执行的情境型和认知型干预策略,一方面便于吸烟者和相关部门选取可执行的戒烟行为干预策略,另一方面为进一步开发和验证助推戒烟的行为干预策略提供参考。虽然基于行为科学的助推干预策略已经取得了一定的进展,未来研究仍有必要进一步在真实世界中验证和评估戒烟助推干预策略的效果。未来也有必要进一步将行为改变技术融入到数字化的戒烟服务或应用小程序中去以提升其效果。未来也需要考察如何应用戒烟助推干预策略防止电子烟产品的负面影响并减少这类策略的误用和滥用。     

认知需求对个体信息加工倾向性的影响

认知需求指"个体参与和享受思考的倾向"。作为一种认知动机,研究者认为其影响了个体信息加工的倾向性。对国外近30年来的相关研究进行回顾,结果显示认知需求主要在努力程度、自主性和结果及其应用范围这三方面影响了个体的信息加工。最后,展望了认知需求的研究趋势,并从认知需求的测量、无关变量的控制、影响的长期性和稳定性,以及情感因素负荷四方面探讨了现有相关研究的不足。     

影响儿童至老年人“位置法”记忆训练效果的因素探析

１１８名儿童、少年、青年、中年和老年被试参加＂位置法＂记忆训练,在训练前后对被试进行了一些认知功能的测查,以探讨被试的年龄及认知能力诸因素对记忆训练效果的影响及其预测性。结果表明：①训练前字词和图形记忆成绩、＂数字符号＂测验成绩与训练后记忆成绩相关极其显著,＂词汇＂测验成绩和想象力与训练后记忆成绩的相关也达到显著性水平;②年龄与训练后记忆效果的关系是非线性的;③除＂词汇＂成绩外,各项认知成绩均可预测训练后字词记忆成绩,训练后的图形记忆迁移效果可由＂数字符号＂测验成绩预测。     

Reducing faking on personality tests: Testing a new faking‐mitigation procedure in a U.S. job applicant sample

Faking has remained a major concern for organizations using self‐report personality measures for selection. Scholars recenlty developed a new middle‐warning faking‐mitigation procedure. The present replication study was the first field test in the United States using 193 applicants for an entry‐level position in a New York‐based consulting firm. Results replicated most of Fan et al.'s findings including (a) the middle‐warning significantly lowered fakers' personality scores over retesting, whereas the control message had little influence on nonfakers; (b) the above warning effect carried over to personality scales that were not retested; and (c) the persistent tendency of potential fakers rising to the top of personality score distribution was weakened. In addition, applicants' perceptions were not being negatively affected by the warning.     

现实及网络社会排斥与大学生抑郁的关系:自我控制的中介作用

对1077名大学生进行调查,探讨现实、网络社会排斥和自我控制与大学生抑郁的关系。结果显示:(1)现实社会排斥与网络社会排斥在发生频率上没有显著差异;网络社会排斥、现实社会排斥、自我控制以及抑郁两两之间均呈显著正相关关系;(2)现实社会排斥不仅能够对抑郁产生直接的预测作用,而且能够通过自我控制的中介作用对抑郁产生影响;(3)网络社会排斥对抑郁的直接预测作用不显著,只能够通过自我控制的中介作用对抑郁产生影响。     

Profiling Perceptual Learning Styles of Chinese as a Second Language Learners in University Settings

This study revisited Reid’s (1987) perceptual learning style preference questionnaire (PLSPQ) in an attempt to answer whether the PLSPQ fits in the Chinese-as-a-second-language (CSL) context. If not, what are CSL learners’ learning styles drawing on the PLSPQ? The PLSPQ was first re-examined through reliability analysis and confirmatory factor analysis (CFA) with 224 CSL learners. The results showed that Reid’s six-factor PLSPQ could not satisfactorily explain the CSL learners’ learning styles. Exploratory factor analyses were, therefore, performed to explore the dimensionality of the PLSPQ in the CSL context. A four-factor PLSPQ was successfully constructed including auditory/visual, kinaesthetic/tactile, group, and individual styles. Such a measurement model was cross-validated through CFAs with 118 CSL learners. The study not only lends evidence to the literature that Reid’s PLSPQ lacks construct validity, but also provides CSL teachers and learners with insightful and practical guidance concerning learning styles. Implications and limitations of the present study are discussed.     

Engagement Attentional Bias toward Value-Associated Stimuli

Recent evidence has shown that learning to associate the value of behavioral outcomes with specific stimuli (i.e., value learning/association) can induce attentional capture in a subsequent visual search task. Here we investigated the component of attentional bias toward value-associated stimuli in the dot-probe paradigm. In the training phase, participants learned to associate nonsense shape outlines with monetary wins or losses. The shapes were then used as cues in an explicit no feedback dot-probe task. Probe appeared at either the salient (congruent trial) or nonsalient location (incongruent trial). Results indicate attentional bias toward value-associated stimuli, futher more this attentional bias is driven by an engagement bias.
