来源记忆中背景的情绪效价与唤醒对提取过程的影响

以往研究表明情绪背景对来源记忆存在影响,但背景的情绪效价和唤醒如何影响熟悉性及回想尚存争议。本研究以ERPs技术作为测量手段,采用来源记忆多键范式,操纵背景的情绪效价及唤醒强度,以探讨编码阶段背景情绪影响来源记忆提取的认知神经机制。学习阶段,呈现中性汉字及情绪图片（正性高唤醒、正性低唤醒、负性高唤醒、负性低唤醒）;测验阶段,仅呈现汉字,被试进行五键判断。行为结果发现：来源正确的比率比来源错误的比率更高,反应时更短;同时提取正性背景的辨别力更强,反应时更短;提取高唤醒背景反应时更短。脑电结果发现了分别代表熟悉性及回想的FN400及LPC新旧效应,且在500～700 ms,提取正性背景及高唤醒背景诱发显著更正的ERPs,但效价与唤醒没有交互作用。总体来说,来源记忆中背景效价及唤醒度对回想过程存在独立影响,体现为正性背景及高唤醒背景对来源提取的促进作用。     

任务与字频对汉字阅读中情绪价效应的影响

两个实验均以汉字为材料,采用2×3被试内设计,分别使用语义范畴判断和语音判断任务考察了汉字频率对阅读中情绪价效应的影响。结果发现：在语义任务中,情绪价与字频之间交互作用不显著,低频消极字和积极字的反应时均快于中性字,高频消极字的反应时也快于中性字,但高频积极字与中性字之间无差异。在语音任务中,情绪价与字频之间交互作用显著,低频消极字和积极字的反应时均快于中性字,而高频字的语音通达则不受情绪价的影响。汉字阅读中的情绪价效应不是自动化的过程,会受到字频与任务形式的影响。     

Perceived Event Frequency and the Optimistic Bias: Evidence for a Two-Process Model of Personal Risk Judgments

People often judge themselves to be at lower risk for various negative life events than are their peers. The two empirical studies presented here show that the magnitude of this optimistic bias can be either negatively or positively related to the perceived frequency of the event, depending on whether people judge their own risk relative to that of an average peer (make comparative risk judgments) or judge their own and an average peer's risk separately (make absolute risk judgments). A new two-process model is presented to account for these results. The model combines a better-than-average heuristic with elements of the singular target-focused and singular- distributional models of Klar and colleagues (Klar & Giladi, 1997, 1999; Klar, Medding, & Sarel, 1996). The empirical results and model have many implications for the study of personal risk judgments, the optimistic bias, and risk-taking behavior.

老年人错误记忆的情绪效价和时间效应

基于信号检测论的框架, 考察不同的情绪效价以及时间间隔如何交互影响老年人在图片再认任务中的辨别力(d′)和判断标准(β), 进而影响其错误记忆。以21名老年人(女性14名)为被试, 平均年龄67.17 ± 5.03岁。根据中国老年人对国际情绪图片库(International Affective Picture System, IAPS)中图片评定的情绪参数, 选出积极、消极和中性图片各60张作为学习材料。另选积极、消极和中性图片各30张作为每次再认测验的干扰材料, 并且两次再认测验的干扰材料不同。短时间隔条件让老年人在图片记忆编码半个小时后完成对图片的再认测验; 长时间隔条件则为在三周后完成对图片的再认测验。结果发现: 1)在短时间隔条件下, β和d′共同影响虚报率; 而在长时间隔条件下, 只有β影响虚报率, d′不影响虚报率; 2)无论是在短时还是长时间隔条件下, 积极图片与消极图片的判别力d′都没有显著差别; 3)在短时间隔条件下, 老年人对消极图片的β更低、虚报率更高; 在长时间隔条件下, 老年人对积极图片的β更低、虚报率更高。研究结果表明: 老年人的错误记忆受判别力d′和判断标准β的影响。情绪效价通过作用于老年人的反应倾向(判断标准β)、而非记忆质量(判别力d′)来影响其错误记忆。时间间隔可以调节情绪效价对老年人判断标准β和错误记忆的作用, 使之随时间发生反转。老年人的“积极效应”在错误记忆中可能表现为随着时间的流逝, 老年人更愿意将积极信息报告为经历或学习过的信息。     

Perceived Change in Life Satisfaction and Daily Negative Affect: The Moderating Role of Purpose in Life

Perceiving changes in life satisfaction has been linked to diminished health and well-being. Purpose in life is theorized to promote well-being by providing a sense of personal consistency, which may buffer the negative consequences of perceived change. Using data from the Midlife in the United States study, a cluster analysis was performed to explore profiles of adults’ (N = 1,746) ratings of life satisfaction for their past, present, and future. The analysis yielded three distinct profiles: continuous high, incremental, and decremental. Relative to the other profiles, decremental adults reported greater levels and variability of negative affect in everyday life. However, purpose moderated these effects such that no between-profile differences in negative affect level or variability were detected for adults reporting greater levels of purpose. Purpose is discussed as an asset for promoting positive adjustment in adulthood.     

A Cognitive-Behavioral Standpoint on the Perceived Consequences of a Major Seismic Event in Relation to Optimism and Pre-hazard Emotional Distress

The study examined a circumscribed class of cognitions (i.e., dispositional optimism and perceived consequences) in connection to the emotional distress experienced in anticipation of a major seismic event (i.e., pre-hazard emotional distress). Grounded on cognitive-behavioral theory, it was argued that dispositional optimism exerts distal influence on distress, while the perceived consequences of a major seismic event are proximal to distress and, therefore, interpose the optimism-distress relationship. The hypothesis was tested via a cross-sectional study on a sample of 189 volunteers located in areas of high seismic hazard. Participants reported their level of pre-hazard emotional distress, their dispositional optimism, and their perceived consequences of a major seismic hazard. The results showed that there was a partial indirect effect from dispositional optimism to emotional distress via perceived consequences, indirect effect = ?0.190, SE = 0.114, 95 % CI [?0.487; ?0.021], k² = 0.051. These findings could inform future prevention programs targeting emotional distress in anticipation of a natural hazard with impact on post-disaster recovery.     

抑郁症的整合情绪记忆模型述评

多种早期情绪记忆模型尝试揭示抑郁症的认知致病原因和机制。但是,抑郁症的致病因素存在多样性,而各个模型只侧重于某个方面,难以全面、系统、准确对其进行的诠释。整合情绪记忆模型将记忆建构、自我图式、自传体记忆、内隐记忆等认知结构进行系统的整合,从编码和提取的角度对抑郁症的的发生、持续和治疗提供新的解释,为抑郁症的预防、治疗提供了新思路。     

不同语义水平下参照方式、情绪效价和特质评价对记忆的影响

为了探索影响记忆的深层次因素及其作用机制,采用内隐实验范式,考察了不同语义水平下参照方式、情绪效价和特质评价对记忆的影响。结果发现,参照方式、情绪效价和特质评价分别对记忆产生了显著的影响;在不同语义水平下,自我相关的特质词和非特质词的记忆优势表现在不同的再认提取阶段;个体对自我相关的消极词表现出显著的记忆优势;参照方式、情绪效价和特质评价的交互作用不显著。结果表明,参照方式、情绪效价和特质评价是对记忆产生影响的独立因素,但参照方式对记忆的影响受到情绪效价和特质评价的制约。     

Using a Gain/Loss Framework to Measure Impact: The Perceived Impact of Life Event Scale

The author describes three interconnected investigations focused on the development and psychometric evaluation of the Perceived Impact of Life Event Scale (PILES), a measure developed using a gain/loss framework for assessing the multidimensional impact of single life events. In Study 1 (N = 160), the author describes the item generation process and results of a pilot study. In Study 2 (N = 244), exploratory factor analysis suggested a 29-item scale with the four following gain/loss factors: existential, discretionary time, romantic relationship/sexual, and career and employment. In Study 3 (N = 244), confirmatory factor analysis indicated a three-factor model (26-item scale), and findings suggested convergent validity of the measure.     

Avoidance Behavior Following Terror Event Exposure: Effects of Perceived Life Threat and Jewish Religious Coping

The current research was designed to examine associations of perceived life threat (PLT) and religious coping with the development of avoidance behavior following terror event exposure. Based upon the terror management theory (TMT), we hypothesized that religious coping, through its effect on religious beliefs as a meaning system, would moderate the impact of threat, as expressed in PLT, on an individual's reaction to terror event exposure, as manifested in avoidance behavior. Participants were 591 Israeli Jewish students who were vicariously or directly exposed to a terror event in the past. We report a significant interaction between PLT and negative religious coping. PLT was positively associated with avoidance behavior but this relationship was more profound among persons who reported high negative religious coping. Secular students reported higher rates of avoidance behavior and negative religious coping and were more likely than religious students to report intrapersonal religious conflict. Our findings suggest that terror event exposure is associated with an elevated sense of threat, which is, at least in part, associated with a weakening of prior religious beliefs.     

Perceived Patient Responsibility and Belief in a Just World Affect Helping

Three experiments reported here uniquely test the effectiveness of warm versus competent advertising strategy as a function of congruence with other elements of the advertising context. These are product involvement (Experiment 1, n = 96), consumers’ smartphone anxiety (Experiment 2, n = 60), or self-versus other-profitability (Experiment 3, n = 100). As expected, the “golden quadrant” (optimum warmth and competence for advertising effectiveness) does shift: Competence is more important for high-involving products, but warmth wins for highly anxious participants or when the highly involving service is accompanied by people-focused appeals. An expansion of the stereotype content model is discussed in the context of the congruity principle.     

Perceptions of Credibility for a Memory Report of a Single Versus Repeated Event

Summary: When a person experiences an event that has multiple similar instances (i.e., a repeated event), memories for details that change across instances are challenging to recall. We expected that third parties would perceive memory reports of instances of repeated events as less credible than they would unique (i.e., single) events. Undergraduates participated in a single or repeated event, during which critical details were presented. Participants were asked to recall the session 2 days later, and memory reports were video recorded. New participants then viewed one video and evaluated the credibility of the speaker's memory report. Overall, repeated‐event reports were seen as less credible than were single‐event reports, despite the reports being equally accurate. Although credibility research in the context of repeated events has focused exclusively on child populations, a range of applications exists for adults (e.g., criminal and industrial eyewitnesses, and asylum seekers); we discussed our findings in these areas.Copyright © 2017 John Wiley & Sons, Ltd.     

Emotional Intelligence,Life Satisfaction,and Psychological Well-Being in Graduates: the Mediating Effect of Perceived Stress

This study investigated the mediating role of perceived stress in the relationship between emotional intelligence and life satisfaction and psychological well-being when controlling for personality traits. The sample included 400 graduates (278 women, 122 men) from the University of Deusto with ages ranging from 22 to 60 years. Data on emotional intelligence, perceived stress, life satisfaction, psychological well-being, and personality factor scales were collected, and bootstrap methods were used to explore the multiple mediator effects. As expected, emotional intelligence was positively associated with life satisfaction and psychological well-being. The final model revealed a significant path from emotional intelligence through perceived stress to life satisfaction and psychological well-being even controlling for personality traits as covariables. Our findings suggest an underlying process by which high emotional intelligence increases well-being in graduates by reducing the experience of stress. Limitations of the results and implications of these findings for future research are discussed.     

Perceived utility of emotion: the structure and construct validity of the Perceived Affect Utility Scale in a cross-ethnic sample

This study introduces a new measure of the perceived utility of emotion, which is the degree to which emotions are perceived to be useful in achieving goals. In this study, we administered this new measure, the Perceived Affect Utility Scale (PAUSe), to a sample of 142 European American and 156 East Asian American college students. Confirmatory factor analyses provided support for a new, culturally informed parsing of emotion and for perceived utility of emotion to be distinguishable from ideal affect, a related but separate construct. Next, we explored the potential importance of perceived utility of emotion in cultural research. Through path analyses, we found that: (a) culturally relevant variables (e.g., independence) played a mediating role in the link between ethnic group and perceived utility of emotion; and (b) perceived utility of emotion played a mediating role in the link between culturally relevant variables and ideal affect. In particular, perceived utility of self-centered emotions (e.g., pride) was found to be associated with independence and ideal affect of those same emotions. In contrast, perceived utility of other-centered emotions (e.g., appreciation) was found to be associated with interdependence, dutifulness/self-discipline, and ideal affect of those same emotions. Implications for perceived utility of emotion in understanding cultural factors are discussed.     

Problem Clarity as a Moderator between Trait Affect and Self‐Perceived Creativity

Empirical studies on the relationship between affect and creativity often produce conflicting results. This inconsistency has led us to believe that the relationship between affect and creativity may be better understood by looking at potential moderators. Our study looked specifically at trait affect and self‐perceived creativity. Using the Affect Infusion Model (AIM) theory with problem clarity as the potential moderator, we hypothesized that when individuals are faced with problems that lack clarity, trait affect has greater sway over their self‐perceived creativity. Our results provided evidence that problem clarity moderated the relationship between positive trait affect and self‐perceived creativity; the positive relationship between positive trait affect and self‐perceived creativity is stronger when problem clarity is low and weaker when problem clarity is high. No moderating effect was found in the relationship between negative trait affect and self‐perceived creativity.     

Perceived Powerlessness as a Mediator between Life Stressors and Deviant Behaviors

ABSTRACT

The Threat Appraisal and Coping Theory suggest that when facing life stressors, individuals may perceive that they are powerless to change them, which may prompt “maladaptive coping” deviant behaviors. The present study examined the relationship between 5 types of deviant behavior and perceived powerlessness, and whether powerlessness served as a mediator between life stressors and deviance. Money stress and powerlessness increased risk for watching porn, cross-dressing, hoarding, and medication misuse. Work stress and powerlessness significantly increased risk for watching porn, cross-dressing, and medication misuse. Family stress and powerlessness increased risk for watching porn, cross-dressing, disordered eating, hoarding, and medication misuse.     

Memory for Actions of an Event: Older and Younger Adults Compared

Previous studies have shown increased false memory effects in older compared to younger adults. To investigate this phenomenon in event memory, in the present study, the authors presented younger and older adults with a robbery. A distinction was made between verbal and visual actions of the event, and recognition and subjective experience of retrieval (remember/know/guess judgments) were analyzed. Although there were no differences in hits, older adults accepted more false information as true and, consequently, showed less accurate recognition than younger adults. Moreover, older adults were more likely than younger adults to accompany these errors with remember judgments. Young adults accepted fewer false verbal actions than visual ones and awarded fewer remember judgments to their false alarms for verbal than for visual actions. Older adults, however, did not show this effect of type of information. These results suggest that aging is a relevant factor in memory for real-life eyewitness situations.     

Judgments of Frequency and Recency in a Distributed Memory Model

TODAM is a theory of distributed associative memory based on the convolution-correlation formalism of A. Borsellino and T. Poggio (1973, Kybernetik, 122, 113-122), and TODAM2 is a revised version which includes context, auto-associations for binding, a dual basis for item information, and mediators for associative information. It can explain some complex interactions (differential forgetting and differential attention) between item and associative information. In this paper we derive the basic expressions for the memory-probe dot product for the 2x2 cases (item and pair study crossed with item and pair probe), and then we apply these expressions to judgments of frequency (JOF) and judgments of recency (JOR). We report an experiment which tests both JOF and JOR for single items with post-cuing to control for encoding strategies and suggest an attenuation factor for repetition to improve the fits. With attenuation, TODAM2 can fit the JOR data, but the JOF fits, while not too bad, consistently predict too much dependence between item and associative information. Copyright 2001 Academic Press.
