提取干扰对不同类型内隐记忆的影响

以往研究关于提取阶段的干扰是否会影响内隐记忆存在着异义, 其中一个重要因素可能源于所采用的内隐记忆测验类型的差异。本研究采用学习-测验范式, 通过4个实验, 分别考察了提取干扰对识别式知觉内隐测验、识别式概念内隐测验、产生式知觉内隐测验和产生式概念内隐测验的影响, 以期对提取干扰和内隐记忆之间的关系有着更全面的了解。结果表明: (1)词汇判断任务(识别式知觉)和语义分类任务(识别式概念)的启动效应在提取干扰下消失了, (2)而产生式词汇判断任务(产生式知觉)和产生式语义分类任务(产生式概念)在提取干扰下仍发现了明显的启动效应, 但与无干扰条件相比, 启动效应量也有着明显的减少。由此可见, 不同类型的内隐记忆都会受到提取干扰的影响, 相比于产生式启动, 识别式启动更容易受到提取干扰的破坏。

乐观偏差研究概况

乐观偏差指个体倾向于认为自己更可能经历积极事件而他人更可能遭遇消极事件的现象。对乐观偏差的测量主要有直接比较和间接比较两种方式。事件特征和个体因素是乐观偏差的主要影响因素。产生乐观偏差的心理机制主要有自我中心主义和聚焦主义。乐观偏差对个体既有积极作用也有消极影响。未来研究主要包括:开发科学可行的测量工具;加强对个体水平乐观偏差的研究;把乐观偏差和悲观偏差结合起来进行研究;对乐观偏差进行认知神经心理机制的探讨。

考察个体对不同社会阶层的公平偏见及内隐态度，对社会治理和发展（如，缓解社会阶层之间矛盾）具有重要意义。通过两项实验对上述问题进行了探讨，采用内隐联想测验(IAT)发现，相对于低社会阶层，个体更易将公平性词汇与高社会阶层相联结（实验1）；也更易将积极性词汇与高社会阶层相联结（实验2）。上述结果表明，个体存在社会阶层偏好，对高社会阶层持有一种更加公平的、积极的内隐认知。     

Perceived Control and the Optimistic Bias: A Meta-Analytic Review

People consistently believe that negative events are less likely to happen to them than to others. Research suggests a relationship between this optimistic bias and perceived control such that the greater control people perceive over future events, the greater their optimistic bias. We conducted a meta-analysis of 27 independent samples to quantify the size of this relationship and examine what variables moderated the relationship. Greater perceived control was significantly related to greater optimistic bias, but this relationship was moderated by participant nationality, student status, risk status, and the type of optimistic bias measure used. We discuss the findings in the context of primary versus secondary control.

研究考查了大学生对一般生活事件和意外事故的乐观与悲观偏差,并检验不同测量方法是否会产生不同结果。通过对273名大学生进行问卷研究,结果发现：（1）在直接和间接测量时,被试对一般消极事件、意外事故存在乐观偏差,对幸免于意外事故存在悲观偏差;但对一般积极事件,被试在直接测量时出现乐观偏差,在间接测量时为悲观偏差。（2）在两种方法中,被试对意外事故的乐观偏差皆高于一般消极事件,但一般积极事件与幸免于意外事故的结果在直接测量时有显著差异,而在间接测量中差异不显著。（3）在直接测量时,消极事件的发生频率越低乐观偏差越严重,积极事件的发生频率越低则悲观偏差越严重;在间接测量中事件频率与偏差结果相关不显著。     

Unrealistic optimism about future life events: a cautionary note

A robust finding in social psychology is that people judge negative events as less likely to happen to themselves than to the average person, a behavior interpreted as showing that people are "unrealistically optimistic" in their judgments of risk concerning future life events. However, we demonstrate how unbiased responses can result in data patterns commonly interpreted as indicative of optimism for purely statistical reasons. Specifically, we show how extant data from unrealistic optimism studies investigating people's comparative risk judgments are plagued by the statistical consequences of sampling constraints and the response scales used, in combination with the comparative rarity of truly negative events. We conclude that the presence of such statistical artifacts raises questions over the very existence of an optimistic bias about risk and implies that to the extent that such a bias exists, we know considerably less about its magnitude, mechanisms, and moderators than previously assumed.     

News of Y2K and Experiencing Y2K: Exploring the Relationship Between the Third-Person Effect and Optimistic Bias

This study gauged Americans' beliefs about predicted Y2K problems during the weeks before New Year 2000. It examined the alleged relationship between the third-person effect and the social psychological theory of optimistic bias. The third-person effect predicts that people judge themselves less influenced than others by media messages. To explain the effect, some media researchers have drawn on optimistic bias, which posits that people judge themselves less likely than others to experience negative life events. Few researchers, however, have directly tested the empirical relationship between the two perceptual approaches. As hypothesized, respondents judged themselves less influenced than others by news reports about Y2K (third-person perception) and less likely than others to experience Y2K problems (optimistic bias). But the study did not find the hypothesized relationship between the approaches. Furthermore, third-person perception and optimistic bias were functions of mirror opposite blocks of predictors. The findings indicate that third-person perception is not merely a media case study of optimistic bias. We suggested that people use different criteria to estimate experiencing events and believing media messages about the events.     

解释水平视角下的乐观偏差效应

研究基于解释水平理论,考查心理距离对乐观偏差效应的影响。实验从心理距离的事件概率维度、时间距离维度、空间距离维度入手,采用自编的材料对677名被试进行测量,探讨心理距离的远近对乐观偏差产生的影响。结果表明,被试对未来生活事件的判断存在总体上的乐观偏差。在较远的心理距离条件下,被试表现出更大的乐观偏差;而在较近的心理距离中,乐观偏差效应明显减小。但在时间距离维度以及消极事件的概率维度上,表现出与总体乐观偏差不一致的现象。     

Automatic optimism: Biased use of base rate information for positive and negative events

People generally judge that positive events will occur in their lives and negative events will not, even when both events have the same objective likelihood to occur. In four studies, we examined the possibility that this optimistic bias is the result of people’s automatic affective reactions to future events. Studies 1 and 2 demonstrate, in two different contexts, that people are consistently optimistic in their predictions, despite identical base rates for positive and negative events. In Study 2, optimistic bias was not influenced by incentives for motivated reasoning or rewards for accuracy, suggesting that bias was the result of automatic processes. Studies 3 and 4 showed that optimistic bias was more pronounced when predictions were speeded and when participants made predictions after exposure to affectively valenced words. Together, these findings suggest that people optimistically interpret base rates and that this optimism is due to an effortless affective process.     

Cultural variations in optimistic and pessimistic bias: do Easterners really expect the worst and Westerners really expect the best when predicting future life events?

The authors compared levels of optimistic and pessimistic bias in the prediction of positive and negative life events between European Americans and Japanese. Study 1 showed that European Americans compared with Japanese were more likely to predict positive events to occur to self than to others. The opposite pattern emerged in the prediction of negative events. Study 2 replicated these cultural differences. Furthermore, positive associations emerged between predictions and occurrence of life events 2 months later for both European Americans and Japanese. Across both studies, results of within-groups analyses indicated that both groups expected negative events to be more likely to occur to others than to self (optimistic bias). In addition, Japanese expected positive events to be more likely to occur to others than to self (pessimistic bias). However, European Americans failed to show the expected optimistic bias for positive events.     

It Won't Happen to Me: An Investigation of Optimism Bias in Occupational Health and Safety

Optimism bias is the tendency to think that negative events are less likely to happen to oneself than to one's peers. Optimism bias concerning occupational health and safety (OHS) hazards was assessed in 105 postgraduate students and university employees. Significant levels of optimism bias were found for several events (e.g., suffering/causing injury). Though optimism bias was not related to perceived controllability, administration of OHS by management may explain why this observation differs from findings in other domains. While further study is required, the present study demonstrates that people tend to think hazardous events at work are less likely to happen to themselves compared to others doing the same job, which has important implications for management of safety at work.
