权力感和任务难度对个体建议采纳的影响

从人际关系的视角,通过两个实验探讨权力感和任务难度对个体建议采纳的影响。实验一启动被试的合理权力感,实验二启动被试的不合理权力感。研究发现：(1)当权力合理时,权力感水平对建议采纳有显著影响,高权力感水平决策者的建议采纳程度显著低于低权力感水平的决策者;任务难度对建议采纳有显著影响,决策者在困难任务中的建议采纳程度显著高于简单任务中。(2)当权力不合理时,在简单任务中,高权力感水平决策者的建议采纳程度显著低于低权力感水平的决策者;而在困难任务中,两者的建议采纳程度没有显著性差异。     

Olympic medals as fruits of comparison? Assimilation and contrast in sequential performance judgments

The authors investigated the evaluative consequences of sequential performance judgments. Recent social comparison research has suggested that performance judgments may be influenced by judgments about a preceding performance. Specifically, performance judgments may be assimilated to judgments of the preceding performance if judges focus on similarities between the two. If judges focus on differences, however, contrast may ensue. The authors examined sequential performance judgments, using data gathered from the 2004 Olympic Games as well as data gathered in the laboratory with students or experienced gymnastics judges as participants. Sequential performance judgments were influenced by previously judged performances, and the direction of this influence depended on the degree of perceived similarity between the successive performances.     

Cueing and Cognitive Conflict in Judge-Advisor Decision Making

The Judge-Advisor paradigm (Sniezek & Buckley, 1989) allows for the study of decision making by groups with differentiated roles. This paper reports a study using this approach to investigate the impact of advice vis-à-vis the judge′s own initial choice. Teams consisting of one judge and two advisors (business students randomly assigned to these roles) were given a choice task (concerning business events) composed of 70 items with two alternatives each. The judges provided final team choices and confidence assessments under one of three conditions: Dependent (judge has no basis for own choice), Cued (judge chooses only after being advised), or Independent (judges makes own tentative choice prior to being advised as well as subsequent final choice). Results showed that this manipulation affected the judge′s final choice accuracy and confidence, leading to the best performance by Independent judges and the poorest by Dependent judges. These data are discussed with respect to theory and data on the cueing effect (Sniezek, Paese, & Switzer, 1990) for individual choice. In addition, the effects on the decision making process of the judge from (a) advisors′ confidence and (b) conflict between advisors′ recommendations are examined in detail. Finally, issues concerning the potential contribution of the Judge-Advisor paradigm to the understanding of social decision making are addressed.     

Influence of angle of view on judges' evaluations of inverted cross in men's rings

The present study focuses on two factors that may influence the accuracy and precision of a judge's evaluation of the angular deviation error in "inverted cross" (angle of the arms away from the horizontal axis). 16 Greek judges of competitive gymnastics participated in an evaluation of the magnitude of the error in the skill. Photographs of the performance of 8 gymnasts were shown to the judges in triplicates in random order from three angles of observation (0 degrees, 45 degrees, and 90 degrees) on a computer screen. The precision in the judges' judgments was best at the 45 degrees angle of observation and at angular deviations of 16 degrees to 30 degrees. Accuracy was influenced both by the judge's angle of observation and the gymnast's angular deviation, as well as by the interaction. Overall, judges may need to improve their ability to evaluate performance through training. Training may incorporate a variety of exercises in judging the inverted cross through augmented feedback of knowledge of results.     

A New Look at Gaze: Preschool Children's Understanding of Eye-Direction

This study challenges the consensus view that children can judge what someone is looking at from infancy. In the first experiment 2-, 3-, and 4-year-old children were asked to judge what a person in a drawing was looking at and which of two people was “looking at” them. Only 6% of 2-year-olds and young 3-year-olds passed both gaze-direction tasks, but over 70% passed an analogous point-direction task. Most older 3-year-olds and 4-year-olds passed all three tasks. Experiment 2 compared children's ability to judge what the experimenter was looking at with performance on the picture tasks. Three-year-olds performed significantly worse than 4-year-olds on the real life and picture gaze tasks. Performances on the two types of gaze task were highly correlated. Experiment 3 included stimuli with the additional cue of head-direction. Even the younger children performed well on these stimuli. These results suggest that, regardless of task format, children cannot judge what someone is looking at from eye-direction alone until the age of 3 years. Weaknesses in the evidence supporting the consensus view are highlighted and discussed.     

From synonyms to homonyms: exploring the role of metarepresentation in language understanding

Doherty and Perner (Metalinguistic awareness and theory of mind: just two words for the same thing? Cognitive Development, 13 (1998), 279–305) report that children’s understanding of synonyms and false belief is dependent on an understanding of the representational mind. Experiment 1 extends this finding by examining children’s understanding of homonyms. Children aged 3 and 4 years were asked to judge whether a puppet correctly selected the second member of a homonym pair. Performance on this task was strongly associated with performance on the false belief task even after chronological and verbal mental age had been accounted for. Experiment 2 incorporated two new tasks: a synonyms task and an adjectives task. Understanding of synonyms and homonyms significantly predicted performance on the false belief task. However, once chronological age was accounted for, only performance on the homonyms task did so. The difficulty experienced on the homonyms task was not due to a reluctance to acknowledge that the puppet can point to a different picture when the the same word label is used twice. Children had no difficulty on the adjectives task when the puppet had to point to a different picture described using the same adjective. The suggestion that the understanding of synonyms, homonyms and false belief are related by a common insight into the representational mind is therefore not supported.     

On the relative importance of linear model and human judge(s) in combined forecasting

When and to what extent should forecasts rely on linear model or human judgment? The judgmental forecasting literature suggests that aggregating model and judge using a simple 50:50 split tends to outperform the two inputs alone. However, current research disregards the important role that the structure of the task, judges’ level of expertise, and the number of individuals providing a forecasting judgment may play. Ninety-two music industry professionals and 88 postgraduate students were recruited in a field experiment to predict chart entry positions of pop music singles in the UK and Germany. The results of a lens model analysis show how task structure and domain-specific expertise moderate the relative importance of model and judge. The study also delineates an upper boundary to which aggregating multiple judgments in model-expert combinations adds predictive accuracy. It is suggested that ignoring the characteristics of task and/or judge may lead to suboptimal forecasting performance.     

视觉观点采择需要抑制控制的参与：一项负启动研究

从抑制控制模型出发,采用负启动范式考察视觉观点采择的认知机制。实验1采用自身体转换任务(N=35) 、实验2采用圆点数量判断任务(N=33)分别考察成人在完成二级和一级视觉观点采择任务时是否需要抑制控制的参与。结果发现,成人在完成两类视觉观点采择任务时均出现了负启动效应,说明当他人观点和自我观点不一致时,个体需要抑制自我的观点才能成功采择他人的观点。     

Évaluer le discernement : une perspective biopsychosociale

Article 388-1 of the French Civil Code states that “in any proceedings concerning him, a minor capable of discernment may be heard by the judge”. Family court judges have the task of assessing the minor's capacity of discernment by having neither a definition of discernment nor a method of evaluation and by being ordered not to use the age criterion. Following a review of the literature, we propose a sketch presenting the components of discernment and the biopsychosocial factors that can affect the discernment of an expressed choice/opinion. The objective of this research is to compare the representation of judges’ discernment in family cases with this sketch. Thirty-two family judges participated in this study. The results show a partial representation of judgment among the judges surveyed, with some factors being under-represented and others never mentioned. The theoretical and practical implications of this research will be discussed.     

Who can spot a potential problem gambler? Testing “it takes one to know one” and acquaintanceship effects in a university student population

How easy is it for individuals to detect low to moderate levels of problem gambling tendencies in others? Are individuals who have problem gambling tendencies themselves, or are close relationship partners, more accurate judges? We examine these questions in two studies involving a total of 336 interacting dyads drawn largely from a university student population. In Study 1 all pairs were strangers, whereas in Study 2 approximately half of the pairs were close. After the “judge” observed the “target” complete a gambling task, the dyad had a face-to-face discussion, with topics including favorite pastimes and personal weaknesses. Judges estimated the target's problem gambling tendencies, and both judges and targets self-reported their own gambling tendencies. There was evidence of modest, albeit somewhat inconsistent, accuracy in individuals’ judgments of the other person's problem gambling tendencies, but no “it takes one to know one” or acquaintanceship effects were apparent. Results also indicated that judges evidenced a projection bias, whereby they saw the target as similar to themselves, especially within close pairs. These results reveal that even after minimal interaction with a stranger individuals can be able to judge the person's gambling tendencies with some accuracy. At the same time, our findings indicating that close others and those with problem gambling tendencies themselves are not more or less tuned in to the early signs of a problem than anyone else suggest that it would be inappropriate to be especially convinced by—or skeptical of—these individuals’ judgments.     

Is she the one? Personality judgments from online personal advertisements

The authors examined the linguistic cues that inform personality judgments from online personal advertisements, and whether these judgments are accurate. Advertisers reported their personality, and 2 sets of naïve judges—including one that was seeking a romantic partner—rated advertisers' personality after reading their ads. Judges' impressions of extraversion, agreeableness, and emotional stability—3 traits that are strongly desired in a romantic partner—were influenced by particular lexical cues, such as word count, emotionality, and profanity. Both sets of judges formed accurate impressions for extraversion, but not other traits. These findings suggest that online daters use linguistic cues to judge the desirability of a potential romantic partner's personality, but that the impressions driven by these cues are not always accurate.     

汉语词汇习得的年龄效应：语义假设的证据

通过三个实验考察了词汇加工中的习得年龄效应。实验一对比了汉字命名和图片命名中词汇习得的年龄效应,发现图片命名中存在着较大的词汇习得的年龄效应,汉字命名中没有出现这种效应。实验二和实验三分别采用语义范畴判断任务和图片语义分类任务,两个实验均发现了词汇习得的年龄效应。实验结果说明,词汇习得的年龄效应至少部分来源于语义加工的层次,结果支持了语义假设的观点     

Dissociating positive and negative influences of verbal processing on the recognition of pictures of faces and objects

Four experiments investigated the role of verbal processing in the recognition of pictures of faces and objects. We used (a) a stimulus-encoding task where participants learned sequentially presented pictures in control, articulatory suppression, and describe conditions and then engaged in an old-new picture recognition test and (b) a poststimulus-encoding task where participants learned the stimuli without any secondary task and then either described or not a single item from memory before the recognition test. The main findings were as follows: First, verbalization influenced picture recognition. Second, there were contrasting influences of verbalization on the recognition of faces, compared with objects, that were driven by (a) the stage of processing during which verbalization took place (as assessed by the stimulus-encoding and poststimulus-encoding tasks), (b) whether verbalization was subvocal (whereby one goes through the motions of speaking but without making any sound) or overt, and (c) stimulus familiarity. During stimulus encoding there was a double dissociation whereby subvocal verbalization interfered with the recognition of faces but not objects, while overt verbalization benefited the recognition of objects but not faces. In addition, stimulus familiarity provided an independent and beneficial influence on performance. Post stimulus encoding, overt verbalization interfered with the recognition of both faces and objects, and this interference was apparent for unfamiliar but not familiar stimuli. Together these findings extend work on verbalization to picture recognition and place important parameters on stimulus and task constraints that contribute to contrasting beneficial and detrimental effects of verbalization on recognition memory.

Integration of perceptual information in word access

According to experiential theories of language comprehension, perceptual information plays an essential role when word meanings are accessed. We conducted four experiments to investigate how different types of perceptual information such as colour and shape are combined during word access. One possibility is that the colour and shape of a word's referent are activated independently from one another and are combined in an additive manner. Alternatively, words might activate perceptual representations via a multiplicative integration of colour and shape. Experiment 1 established that participants follow a multiplicative similarity rule when they judge the similarity of schematic pictures to actual fruits and vegetables. In Experiments 2 to 4, participants performed a classification task, a lexical decision task, or a word-naming task on names of fruits and vegetables that were superimposed on a background picture. Responses were facilitated only when both colour and shape of the picture matched the word's referents. Response times were associated negatively with mean similarity ratings and the consistency of these ratings obtained in the first experiment. These results suggest a multiplicative integration of different types of perceptual information during word access.     

Are Arabic numerals processed as pictures in a Stroop interference task?

In a picture-word interference task, picture naming is interfered by an incongruent word, but word naming is hardly hindered by the presence of an incongruent picture. In this study, we investigated whether Arabic digits are processed more like pictures or like words. We report two experiments in which Arabic digits and verbal numerals were confronted in a Stroop task. Arabic digit naming is interfered by the presence of an incongruent verbal numeral, while naming the verbal numeral is not influenced by the presence of an incongruent Arabic digit. In a second experiment, we excluded the hypothesis that the results are due to ignoring the Arabic digits: interferences from an incongruent distracter were similar for both notations in a semantic classification task. It seems that an asemantic conversion for Arabic digits is too slow to influence naming times, and that Arabic digit naming, like picture naming, is semantically mediated.     

PREDICTIVE EFFICIENCY AS A FUNCTION OF AMOUNT OF INFORMATION

The effect of changing the amount of information on judges' predictive efficiency in a clinical prediction task was studied. Thirty judges predicted 30 students' average achievement scores on the basis of different amount of test data. One group of judges had information about the intercorrelations among the tests and the ecologkal validity of the tests. Another group of judges had only informahion about which tests were used. The predictive efficiency was not a monotonically increasing function of amount of test data. The most marked result was that the relative predictive efficiency decreased from four to six tests in both groups.     

自闭症儿童对情景事件的情绪理解：基于内隐和外显的测量

该研究旨在采用生态效度更高的情绪情景事件以及内隐和外显两种测量方式考察自闭症儿童的情绪理解。选取自闭症和智商匹配的正常儿童各21名,以序列图片的方式呈现从动画片中截取的不同效价的情景事件,外显任务要求被试直接判断事件主角的情绪、内隐任务要求被试判断事件的一致性。结果发现：1.在外显任务中,自闭症儿童对正性和负性情绪的判断正确率均显著不如正常儿童,尤其是在负性情绪上存在明显的理解缺陷;2.在内隐任务中,正常儿童的正性负性情绪、自闭症儿童的正性情绪都表现出更弱的相对于中性情绪的理解效应;自闭症儿童的负性情绪理解则在两种任务中都接近于无。这些结果意味着自闭症儿童在外显和内隐任务中都存在负性情绪理解缺陷。     

Reversing roles: a cognitive strategy for undoing memory deficits associated with token status

Tested whether having tokens (Ts) adopt the role of judge reduces cognitive deficits; examined several hypotheses to explain these deficits. In 3 experiments, Ss were asked to remember as many as possible of opinions exchanged in a group interaction with 3 actors. Experiment 1 demonstrated that judging majority members helped gender Ts improve their memory and ruled out self-denigration as a mediator of token deficits. Experiment 2 indicated that judging others was effective regardless of whether the others were said to know about it or not, ruling out insulation from evaluative scrutiny as a viable mediator for the judge role. Experiment 3 suggested the judge role restores completely the Ts, cognitive capacities and ruled out heightened responsibility as an explanation for the improved memory of judges. This work suggests that Ts may perform better if they can restructure cognitively their social environments.
