记忆的自我参照效应

自我参照效应(self-reference effect)指的是记忆材料与自我相联系时的记忆效果显著优于其他编码条件。自我对记忆的促进作用,存在多种理论解释,最主要的有:精细加工说,组织加工说以及双过程说。自我参照效应的研究为应用脑功能成像技术对自我进行脑定位提供了一个新的视角,为情节记忆的HERA模型提供了有力的证据。目前,自我参照效应的研究同文化差异研究相结合,成为一个新的研究趋势。     

早期情绪性对学前儿童问题行为和社交能力的影响

本研究拟考察早期各种情绪性成分及其交互作用对学前儿童问题行为和社交能力的影响。被试为299名儿童及其父母。母亲在儿童6和14个月时报告儿童的各种情绪性成分,父母在儿童48个月时分别报告儿童的问题行为和社交能力。结果发现：（1）6个月时的受限后沮丧和恐惧不能显著预测学前儿童的问题行为与社交能力,但14个月时的受限后沮丧能显著正向预测外显问题行为,恐惧能显著正向预测内隐问题行为,负向预测社交能力。6和14个月时的微笑/大笑均能显著正向预测社交能力。（2）在14个月时,恐惧能显著负向预测高受限后沮丧的学前儿童的社交能力,但不能显著预测低受限后沮丧的学前儿童的社交能力;在14个月时,恐惧能显著负向预测低微笑/大笑的学前儿童的社交能力,但不能显著预测高微笑/大笑的学前儿童的社交能力。     

跨领域项目间联结记忆中项目提取和关系提取的分离：一项事件相关电位研究

使用ERPs技术, 探讨跨领域项目间联结记忆中项目提取和关系提取的差异。学习阶段, 系列呈现面孔-事件动词材料, 让被试识记面孔、事件动词以及两者之间的关系; 测验阶段, 要求被试对成对刺激进行“相同”、“重组”或“新”判断。结果发现：提取阶段, 刺激呈现后约200 ms, “相同”、“重组”和“新”3种条件下的ERPs开始出现分离, 存在“相同/新”、“重组/新”和“相同/重组”三类新旧效应。在200~300 ms, “相同/新”和“重组/新”两类新旧效应表现在前额和额区皮层; 在300~500 ms, 这两类新旧效应广泛地分布在从前到后各个脑区皮层; 在500~700 ms, “相同/新”新旧效应出现在额-顶区皮层, 而无“重组/新”新旧效应; 在700~1400 ms, 这两类新旧效应发生在前额和额区皮层; 在上述4个时段, “相同/重组”关系新旧效应都发生在额中-中央-顶区皮层。从这些结果可以推知：跨领域项目间联结再认中, 项目新旧效应和关系新旧效应同时出现, 但是关系提取比项目提取较晚完成; 额中-中央-顶区皮层关系新旧效应反映了对项目间关系的回忆加工; 而700 ms以后, 前额、额区皮层新旧效应可能反映了项目之间关系提取过程的执行加工功能。     

Conditional same/different concept learning in the short‐beaked echidna (Tachyglossus aculeatus)

Echidnas have evolved separately from other mammalian groups for around 200 million years and incorporate a mixture of reptilian and mammalian features. Because of these attributes, they have historically been considered “primitive” animals. However, they have successfully adapted to a wide variety of ecological niches and their neurophysiology demonstrates a number of unusual and apparently sophisticated characteristics, including a relatively large brain and cerebral cortex and a comparatively massive frontal cortex. Studies of learning in the echidna have thus far been limited to only a handful of experiments which demonstrated relatively basic abilities such as forming a position habit in a T‐maze, successive habit‐reversal learning, and simple visual and instrumental discrimination. This study aimed to expand on these results and test the “primitive” echidna on what are generally considered more advanced cognitive tasks—same/different and conditional same/different concept learning. The results demonstrated that echidnas are able to discriminate on the basis of a relational same/different concept, using simultaneously presented multi‐element stimuli, and transfer that discrimination to novel stimuli. After further training, they were then able to repeat the performance when the correct choice was conditional on the background color of the stimulus panels.     

Effects of treatment‐integrity failures on a response‐cost procedure

Effects of incorrect or partial implementation (poor treatment integrity) on response cost are largely unknown. We evaluated reduced treatment integrity during response cost on rates of 2 concurrently available responses. College students earned points by clicking on either a black circle or a red circle on a computer screen. Experiment 1 compared 2 types of treatment‐integrity failures (omission and commission errors) across 2 levels of integrity (20% and 50%). Compared to 100% integrity conditions, omission errors did not suppress responding to the same extent, and commission errors reduced target responding but also decreased rates of alternative behavior. Experiment 2 compared the effects of 20% and 50% omission errors within subjects. Implementation at 50% integrity adequately suppressed responding, but treatment effects were lost at 20% integrity. There may be a critical level at which response cost must be implemented to suppress responding, which has important implications for application.     

JPSSM since the beginning: intellectual cornerstones,knowledge structure,and thematic developments

Bibliometric analyses are applied to 35,975 citations from 721 articles published in the Journal of Personal Selling & Sales Management, spanning the journal’s first 35 years of existence (1980–2015). For each of three time periods (1980s, 1990s, and 2000s), the sales literature’s most influential article publications are objectively identified. Multidimensional scaling is then used to identify key intellectual themes across time. Based on the citation data, historical developments in the literature regarding (1) relationship marketing, (2) sales force technology, (3) sales force control systems, and (4) salesperson role stress are traced and briefly explored in some article-level depth. Co-citation trends and recently influential papers are used to identify opportunities for future research. Altogether, this paper presents a first-of-its-kind view of sales literature’s intellectual cornerstones, knowledge structure, and thematic developments over 35 years.     

急性心理性应激对自我参照记忆的影响

已有研究表明急性心理性应激会导致个体的自传体记忆受损,然而急性心理性应激如何影响个体加工当前的自我相关信息,还没有研究结论,本研究旨在丰富和拓展这一领域的研究,从而更加全面深入的了解急性心理性应激对自我相关信息的影响。本研究将自我参照记忆的R/K(记得/知道)范式与特里尔社会应激测试(Trier Social Stress Test:TSST)相结合,考察59名处在不同急性心理性应激状态下的被试自我参照记忆的成绩。结果发现高应激反应组自我参照的R回忆率值显著低于低应激反应组,研究结果发现,被试在特里尔社会应激测试过程中的急性心理性应激反应越强,自我参照的R回忆率越低。结果表明急性心理性应激会抑制个体对当前自我相关信息的加工,削弱了自我参照记忆。     

Familial Influences on Dating Violence Victimization Among Latino Youth

Despite theoretical and empirical evidence suggesting that the family environment plays a central role in Latino youth development, relatively little is known about how family processes influence dating violence victimization among Latino adolescents. To address this gap in the literature, we used data from 210 Latino parents and their 13- to 15-year-old adolescents to examine associations between several different family processes, including both parenting practices (parent monitoring, parent–adolescent communication) and aspects of the family relational climate (family cohesion, family conflict, acculturation conflict) and psychological, physical, and sexual dating violence victimization. Consistent with expectations, lower levels of family cohesion and higher levels of family and acculturation conflict were associated with risk for dating violence victimization, although associations varied depending on victimization type. In contrast, neither parental monitoring nor parent–adolescent communication was significantly associated with any type of dating violence victimization. In addition, we found that parent, but not teen, Anglo-American acculturation was associated with higher dating violence victimization risk. Findings suggest that family-based dating abuse prevention programs for Latino youth should seek to increase family cohesion and decrease family conflict, including acculturation-based conflict.     

L’évaluation du risque et des besoins criminogènes à la lumière des données probantes : une étude de validation de la version française de l’inventaire de niveau de service et de gestion des cas – LS/CMI

IntroductionInstruments of the LS family are among the world's most widely used risk assessment instruments.ObjectiveThis study is testing the psychometric properties of the French version of the Level of Service/Case Management Inventory (LS/CMI; Andrews, Bonta, & Wormith, 2004).MethodReliability and predictive validity of the scales, as well as the total scale are tested on a sample of 3682 offenders (301 women and 3381 men) serving a sentence of less than two years.ResultsResults indicate psychometric properties consistent with the English version. Internal consistency, exploratory factor analysis, and predictive validity are good.ConclusionThe current French version of the LS/CMI is a reliable and valid instrument to assess risk for recidivism, and is a solid foundation to support correctional treatment implementation.
