Cultural differences in distraction processing: influence of context at retrieval

Cultural differences in information processing affect perceptual judgment, attention, and memory. We investigated whether cultural differences in processing patterns, specifically East Asian participants’ tendency to encode holistically, compared to Western tendencies to process analytically, affect performance on an implicit memory test. First, participants completed a 1-back task on pictures with superimposed distracting words. After a delay filled with a computerised Corsi block task, they performed a word fragment task in which some fragments could be completed with the distracting words from the 1-back task. Critically, fragments were presented with the same pictures as previously seen (matched condition), with no pictures (control condition), or with pictures from other trials on the 1-back task (mismatched condition). Non-Asian Canadian participants showed virtually no priming for distraction, independent of the reinstatement of encoding context. East Asian Canadian participants showed superior priming for fragments that had been paired with their original pictures. They did not show evidence of a detriment for the mismatched, relative to control, condition.     

Evaluation of two short-term stress interventions in the context of mobility

ObjectivesIn our lives we experience different types of stress that emanate from a variety of situations. This stress can potentially spill over into unrelated situations, including the operation of a vehicle in a safe manner. It is not well known which types of countermeasures can actually mitigate such stress during driving. For this purpose, one needs valid stress intervention methods for the different types of stress that commonly occur during driving. In this study, it was therefore evaluated whether or not two stress interventions were effective in reducing stress. These two stress interventions were Positive Psychology–i.e., being an activity to reflect about thankful moments–and Biofeedback–i.e., being an activity aimed at continued relaxation based on the display of the participants own stress level.MethodsA study with 41 (n = 21 male) participants was conducted in a stationary vehicle to evaluate the effectiveness of Positive Psychology and Biofeedback on stress reduction. Stress was induced using the Stroop Task. During a Stroop Task high stress is caused by naming color words displayed in another, incongruent color. In the Baseline Condition, participants looked at neutral images, which were expected to have no effect on stress levels. These conditions were then compared.FindingsThe results revealed that participant stress levels were significantly higher during each stress induction period in comparison to each stress intervention period. This indicated that a reduction of stress is possible by administering stress interventions in a stationary setting. Yet, there was no difference between Positive Psychology, Biofeedback, and the Baseline Condition, supposedly due to the short administration, stress-reducing attributes of the Baseline Condition itself, or regression to the mean effects.NoveltyThe overall goal of this research is the development of stress interventions to target different types of stress that can occur in the context of mobility, an application context not yet investigated. These interventions are expected to improve well-being and safety inside the vehicle by improving concentration, attention, and psychomotor control, which can be reduced by high stress. The study took a first step to achieve this goal by developing and evaluating Positive Psychology and Biofeedback as stress intervention activities to mitigate stress in a stationary vehicle–a situation comparable to automated driving. The developed interventions showed stress-reducing effects in the stationary setting whereas looking at neutral pictures–although serving as the baseline–was similarly stress-reducing. This enables the next step–adding the task of manual driving to the interventions to look into both the effectiveness of the interventions during manual driving and driving safety at the same time.     

不同情境转换对重复学习条件下类别-例词回忆的影响

为了考察重复学习条件下内部心境转换和外部情境转换对类别-例词回忆的影响,本研究参考提取练习范式,进行了两个实验。实验1选取96名被试,在初始学习与重复学习阶段之间通过指导语操纵被试维持初始学习时的心境,或转换为合作心境,或转换为竞争心境;实验2选取64名被试,被试在不同外部情境中进行初始学习和重复学习,测试时或处于初始学习的情境,或处于重复学习的情境。回忆测验的结果显示:与未经历重复学习的基线词相比,同类别重学的例词回忆率高于基线词,表现出促进现象;当发生内部心境转换,或发生外部情境转换且在重复学习的情境测试时,同类别中未重学例词的回忆率低于基线词,表现出削弱现象;当发生外部情境转换但在初始学习情境测试时,同类别未重学例词的回忆却高于基线词。可采用联结凸显-曝光-线索扩展性的三维度观点解释这一结果。     

积极情绪提高背景线索学习的适应性

背景线索的学习缺乏适应性, 这种缺乏表现在两个方面：其一是难以在已习得的场景表征上捆绑一个新目标位置(Re-learning), 也就是场景表征的更新受阻; 其二是在习得一组场景表征后, 难以学习另一组全新场景(New-learning)。研究表明, 在旧场景表征上捆绑一个新目标位置的能力可能与注意范围大小有关, 而学习全新场景则需要重置学习功能。积极情绪可以有效扩大注意范围, 并改善对旧有认知模式的固着, 因此积极情绪启动将有可能提升背景线索学习的适应性。本研究采用效价为中性和积极的情绪性图片来启动对应的情绪, 探索旧场景捆绑新目标位置时和学习全新场景时, 背景线索的学习情况, 验证积极情绪是否可以提高背景线索学习中的适应性。实验发现, 积极情绪无法促进旧场景上捆绑新目标位置的背景线索学习(Re-learning), 但是可以促进全新场景的学习(New-learning)。该结果说明, 积极情绪可以提高被试的场景学习能力进而促进对全新场景的学习, 却无法减少由表征相似性引起的旧表征的自动检索, 进而无法改善旧表征的更新过程。     

The temporal structure of goal-directed and habitual operant behavior

Operant behavior can reflect the influence of goal-directed and habitual processes. These can be distinguished by changes to response rate following devaluation of the reinforcing outcome. Whether a response is goal directed or habitual depends on whether devaluation affects response rate. Response rate can be decomposed into frequencies of bouts and pauses by analyzing the distribution of interresponse times. This study sought to characterize goal-directed and habitual behaviors in terms of bout-initiation rate, within-bout response rate, bout length, and bout duration. Data were taken from three published studies that compared sensitivity to devaluation following brief and extended training with variable-interval schedules. Analyses focused on goal-directed and habitual responding, a comparison of a habitual response to a similarly trained response that had been converted back to goal-directed status after a surprising event, and a demonstration of contextual control of habit and goal direction in the same subjects. Across experiments and despite responses being clearly distinguished as goal directed and habitual by total response rate, analyses of bout-initiation rate, within-bout rate, bout length, and bout duration did not reveal a pattern that distinguished goal-directed from habitual responding.     

Wrongness in different relationships: Relational context effects on moral judgment

ABSTRACT

Morality primarily serves social-relational functions. However, little research in moral psychology investigates how relational factors impact moral judgment, and a theoretically grounded approach to such investigations is lacking. We used Relational Models Theory and Moral Foundations Theory to explore how varying actor-victim relationships impacts judgment of different types of moral violations. Across three studies, using a diverse range of moral violations and varying the experimental design, relational context substantially influenced third-party judgment of moral violations, and typically independent of several factors strongly associated with moral judgment. Results lend novel but mixed support to Relationship Regulation Theory and provide some novel implications for Moral Foundations Theory. These studies highlight the importance of relational factors in moral psychology and provide guidelines for exploring how relational factors might shape moral judgment.     

Mothers' and Fathers' Parenting Quality and Toddlers' Interactive Behaviours in Dyadic and Triadic Family Contexts

Based on a family systems perspective, this research examined the role of parental gender and family play context in parent–toddler interactions and how behaviours of family members influence each other. Sixty‐seven mostly White, middle‐class families consisting of a mother, father and toddler were videotaped in three separate sessions: mother–child, father–child and both parents–child at a university laboratory setting. The results indicated that there were significant main effects of both parent gender (mother versus father) and context (dyadic versus triadic) on parents' positive and negative parenting and children's engagement and negativity toward parents. Higher levels of mutual engagement between mothers and toddlers were associated with lower levels of fathers' positive parenting and children's engagement with fathers, when moving from the dyadic to the triadic play context. However, fathers' mutual engagement with toddlers was not associated with mothers' parenting quality and child interactive behaviours with mothers. There were also interaction effects of parent gender and context on parents' negative parenting and children's engagement and negativity toward parents. This study adds unique insights to the differences and similarities of parent–child dyadic and triadic interactions during toddlerhood. Copyright © 2012 John Wiley & Sons, Ltd.     

习惯研究的现状与展望

习惯是一种由某特定线索引发并指向某特定目标(包括外显目标与内隐目标)的自动化反应。它具有过去有行为的重复、环境线索的稳定与自动化的反应等特征。关于习惯的测量方式主要采取自我报告法（如自我报告过去行为频率、自我报告习惯频率、自我报告习惯索引等）和反应频率测量法。对习惯的形成的理论解释主要有环境促进、态度促进、目标促进等几种观点。未来研究应继续深入探讨习惯的本质、整合形成机制的相关理论及开发更可靠方便的测量工具。
