THE DISTINCTIVENESS EFFECT IN SOCIAL CATEGORIZATION:

Abstract— Three studies tested the hypothesis that people assume that the identities of other people are tied more closely to their distinctive than to their nondistinctive traits. In Studies 1 and 3, subjects predicted the preferences of a target person who was a member of both a statistically distinctive and a statistically nondistinctive category (e g, sky diver and tennis player). In Study 2, subjects judged the degree of interpersonal similarity between pairs of people sharing distinctive as opposed to nondistinctive category memberships. Consistent with the hypothesis, subjects linked targets with their more distinctive traits and assumed targets would be more similar to people who shared their distinctive traits than to people who shared their nondistinctive traits. The implications of this distinctiveness effect for an understanding of stereotyping are explored.     

THE COUNTERNULL VALUE OF AN EFFECT SIZE:

We introduce a new, readily computed statistic, the counternull value of an obtained effect size, which is the nonnull magnitude of effect size that is supported by exactly the same amount of evidence as supports the null value of the effect size In other words, if the counternull value were taken as the null hypothesis, the resulting p value would be the same as the obtained p value for the actual null hypothesis Reporting the counternull, in addition to the p value, virtually eliminates two common errors (a) equating failure to reject the null with the estimation of the effect size as equal to zero and (b) takmg the rejection of a null hypothesis on the basis of a significant p value to imply a scientifically important finding In many common situations with a one-degree-of-freedom effect size, the value of the counternull is simply twice the magnitude of the obtained effect size, but the counternull is defined in general, even with multidegree-of-freedom effect sizes, and therefore can be applied when a confidence interval cannot be The use of the counternull can be especially useful in meta-analyses when evaluating the scientific importance of summary effect sizes     

THE RATCHETING‐UP EFFECT

I argue for the existence of a ‘ratcheting‐up effect’: the behavior of moral saints serves to increase the level of moral obligation the rest of us face. What we are morally obligated to do is constrained by what it would be reasonable for us to believe we are morally obligated to do. Moral saints provide us with a special kind of evidence that bears on what we can reasonably believe about our obligations. They do this by modeling the level of sacrifice a person can realistically bear. Exposure to moral saints thus ‘ratchets‐up’ our obligations by combating a type of ignorance that would otherwise defeat those obligations.     

ON THE EINSTELLUNG EFFECT IN PROBLEM SOLVING: Some critical remarks

Objections are raised to Luchins' interpretation of the Einstellung effect and his negative evaluation of this effect. It is proposed to shift the emphasis from behavior to perception. The subject does not develop a 'bad' habit, but acts according to the specific type of problem which the experienced situation seems to present. Two types of problems are distinguished: whole problems, in which the critical problems in the Einstellung experiments are perceived as application situations, and part problems, in which the critical problems are perceived as problems in their own right.     

IN DEFENSE OF THE BODY: THE EFFECT OF MORTALITY SALIENCE ON FEMALE BODY OBJECTIFICATION

Previous research has illustrated the negative psychological consequences of female body objectification. The present study explores how female body objectification may serve as a defense against unconscious existential fears. Drawing from terror management theory, an experiment was designed to test the potential functionality of female body objectification. Men and women were primed to think about either their own mortality or an aversive control topic, and levels of body objectification were then assessed for both self- and other (women)-objectification. Findings supported the hypothesis that priming mortality would increase both self- and other-objectification among women, and self-objectification among those who derive self-esteem from their body. Implications for this research are discussed.     

任务难度对于返回抑制出现时间的影响

在返回抑制的范式下,以大学生为被斌,采用线索一靶子模式进行了两项实验.实施一发现,在觉察任务中,返回抑制在线索和靶子的时间间隔(SOA)为300ms时出现;在辨别任务中,返回抑制在SOA为700ms时出现.实验二发现在选择任务中,返回抑制在SOA为1300ms时出现.这些结果表明,随着实验任务的难度逐渐增大,返回抑制出现越来越晚.实验任务的难度是影响返回抑制出现时间的一个重要因素.     

THE EFFECT OF MOOD ON THE RELIABILITY OF ESSAY ASSESSMENT

Summary . One potential source of bias that has not been examined in relation to the grading of essays is that of the mood of the marker. Several lines of research in social psychology can be generalised to predict different assessment outcomes as a function of mood. This study examined the effect of mood on student grading of children's essays. Markers first watched a film designed to induce either a positive or a negative mood state. They then graded nine essays, including a number of target essays. Mood affected only the first essay graded. The results do not support a mood effect in essay assessment.     

THE DISRUPTIVE EFFECT OF SELF-OBJECTIFICATION ON PERFORMANCE

Self-objectification is the act of viewing the self, particularly the body, from a third-person perspective. Objectification theory proposes numerous negative consequences for those who self-objectify, including decreased performance through the disruption of focused attention. In the current study, we examined whether women in a state of self-objectification were slower to respond to a basic Stroop color-naming task. Results showed that regardless of the type of word (color words, body words, or neutral words), participants in a state of self-objectification exhibited decreased performance. This study lends further evidence to objectification theory and highlights the negative performance ramifications of state self-objectification.     

THE EFFECT OF MODELLING ON DRINKING RATE

Three male college seniors were asked to drink beer at their normal rate in a simulated tavern setting. Each was paired with a confederate, also a male college senior, in an ABACA single subject design. In the baseline conditions, the confederate matched the drinking rate of the subject. Baseline and all subsequent conditions were continued in 1-hr sessions until a stable drinking rate was achieved. In Condition B, the confederate drank either one third more or one third less than the subject's baseline rate. In Condition C, the direction was reversed. All three subjects closely matched the confederate's drinking rate, whether high or low. All subjects reported they were unaware of the true purpose of the study.     

THE DISJUNCTION EFFECT IN CHOICE UNDER UNCERTAINTY

Abstract —One of the basic axioms of the rational theory of decision under uncertainty IS Savage's (1954) sure-thing principle (STP) It states that if prospect x is preferred to y knowing that Event A occurred, and if x IS preferred to y knowing that A did not occur, then x should be preferred to y even when it is not known whether A occurred We present examples in which the decision maker has good reasons for accepting x if A occurs, and different reasons for accepting X if A does not occur Not knowing whether or not A occurs, however, the decision maker may lack a clear reason for accepting X and may opt for another option We suggest that, in the presence of uncertainty, people are often reluctant to think through the implications of each outcome and, as a result, may violate STP This interpretation is supported by the observation that STP is satisfied when people are made aware of their preferences given each outcome

智力和元认知技能在发现学习中的作用:任务复杂性的影响

采用自编的计算机模拟发现学习任务,以49名大学生为被试,探讨了在简单和复杂发现学习任务中,智力、元认知技能和学习成绩三者之间的关系。结果发现:在简单任务中,三者关系基本符合混合模型;进行过多的元认知活动,并不能提高学习效果。在复杂任务中,智力对学习成绩起主要预测作用。随着任务复杂性的增加,智力对学习的影响也随之变化,符合难度阈限理论的假设。任务复杂性不同时,智力、元认知技能和发现学习成绩之间的关系也不同,在一定程度上验证了难度阈限扩展理论。     

SOCIAL COMMUNICATIVE ANXIETY AND THE PERSONNEL SELECTION PROCESS: TESTING THE SIMILARITY EFFECT IN SELECTION DECISIONS

Three studies tested competing predictions about the role of similarity in personnel selection decisions. Previous research suggests a significant role for applicant-selector similarity in the determination of selection decisions. Applicants who are similar to selectors are evaluated, by selectors, more positively than dissimilar applicants. The current investigations found that when the object of similarity is the applicant's and selector's level of anxiety, this relationship fails to appear. Regardless of the selector's own level of anxiety, the high anxious applicant is less positively evaluated than the low anxious one. This effect appears even when the communication demands of the position are specified.     

启动效应再探──预诱发提取策略和启动刺激显现时间的影响

本研究旨在发现启动效应与启动刺激呈现时间及预诱发提取策略的关系．实验Ⅰ表明在不同的建阈值的判断任务之后,语义启动效应随启动刺激呈现时间的减少而减小,但减小到某一值后又开始增大,而重复启动效应则随启动刺激呈现时间减少而增本,但增大到某一值后又开始减小,这一结果为证明中心──周围提取假说（Ｃａｒｒ,１９９０）提供了证据．实验Ⅱ的结果是：在相同的提取策略下,启动效应随启动刺激呈现时间的延长而增大,这一结果充分说明无意识知觉加工的作用;而在相同的呈现时间下,提取策略对启动效应的作用受启动刺激呈现时间长短的制约：当呈现时间达到或超过某一值时,提取策略导致启动效应是“Ｕ”型,小于该值时,提取策略则不起作用。     

THE EFFECT OF WATER IMMERSION ON PERCEPTION OF THE VISUAL VERTICAL

Judgements of the apparent vertieality of a single visible line of light were compared under normal support conditions and under water. During head, body and trunk tilts up to 40° the visual vertical was not influenced by water immersion. Greater degrees of lateral body tilt (up to 180°) resulted in slightly greater departures of the visual from the gravitational vertical during immersion relative to terrestrial performance. It was suggested that this was due to the reduction of information from surface pressure receptors in the trunk. The mean visual aftereffects following head, body and trunk tilts were not affected by water immersion in any consistent manner. It was concluded that visual orientation constancy is only marginally reduced by immersion in water.
