Judgments of the fairness of using performance enhancing drugs

Undergraduates (total N=185) were asked about performance-affecting drugs. Some drugs supposedly affected athletic performance, others memory, and other attention. Some improved performance for anyone who took them, others for the top 10% of performers, others for the bottom 10%, and finally, yet other drugs worked only on the bottom 10% who also showed physical abnormalities. Participants were asked about the fairness of allowing the drug to be used, about banning it, and about whether predictions of future performance based on testing with or without the drug were better. The study found that participants appreciated the "interaction effect," that they felt it was less unfair to allow the drug if it affected the bottom 10% than if it affected everyone, and they were more eager to have the drug banned if it affected everyone. Participants were least tolerant of drugs that affected athletic performance and most tolerant of those that affected attention.     

The Effects of Implicit Theories on Exercise Motivation

This study investigated whether type of implicit theory about athletic coordination would influence motivation to persist at a novel exercise task in the face of difficulty. Fifty college students were told that we were testing a new type of exercise and were given one of two theories about the nature of athletic coordination. Some participants were told that athletic coordination was mostly learned (incremental condition), while others were told that athletic coordination was genetically determined (entity condition). Participants initially experienced success and then difficulty while following videos containing the new exercise. Consistent with predictions, results showed that participants given an incremental theory of athletic coordination reported greater motivation and self-efficacy and less negative affect in the face of difficulty than those given an entity theory. Implications of these findings are discussed.     

“You throw like a girl:” The effect of stereotype threat on women's athletic performance and gender stereotypes

Objectives“Stereotype threat” occurs when people perform worse at a task due to the pressure of a negative stereotype of their group's performance. We examined whether female athletes may underperform at an athletic task if prompted to think about gender stereotypes of athleticism. We also explored whether gender stereotypes regarding general athletic ability would be affected by a standard stereotype threat induction.DesignWe used a 2 (participant gender) × 2 (stereotype threat manipulation) factorial design with task performance and gender stereotypes of athleticism as dependent measures.MethodFemale and male tennis and basketball college student athletes performed two athletic tasks relevant to their sport: a difficult concentration task and an easier speed task. Participants were told beforehand that (1) there was a gender difference on the tasks (to induce stereotype threat) or (2) there was no gender difference (to remove any preexisting stereotype threat).ResultsOn the difficult task, women performed worse than men only when stereotype threat was induced. Performance on the easier speed task was unaffected by the stereotype information. Interestingly, women's beliefs regarding women's and men's general athleticism were also affected by the manipulation.ConclusionsWe concluded that one minor comment regarding a very specific athletic task may sometimes impair task performance and alter gender stereotypes of athleticism among women. Some implications for preventing negative stereotype threat effects are discussed.     

A sham drug improves a demanding prospective memory task

Every day, people rely on prospective memory--our ability to remember to perform a future action--to carry out myriad tasks. We examined how a sham cognitive enhancing drug might improve people's performance on a prospective memory task. We gave some people (but not others) the sham drug, and asked everyone to perform a high-effort prospective memory task. People who received the sham drug performed better on the prospective memory task. They also took longer to perform their ongoing task, suggesting that they increased their effortful monitoring. These results fit with research showing that suggestions can lead people to increase cognitive effort and increase memory performance.

The Ethics of “Smart Drugs”: Moral Judgments About Healthy People's Use of Cognitive-Enhancing Drugs

What moral concerns are relevant when judging the use of cognitive-enhancing (CE) drugs by healthy people? University students evaluated competitive fairness, distributive fairness, peer pressure, naturalness, and dosage form. Participants condemned CE drug use when there were long-term negative effects on health and when CE drug use was seen to provide an unfair advantage in an exam situation to someone while others were not taking the drugs. Further, participants judged CE drug use more harshly if the drugs were artificial rather than natural and if they were in the form of an injection rather than a pill, suggesting that moral intuitions relating to purity also influence opinions on CE drugs.     

Physical Attractiveness Bias in Employee Termination

We examined the impact of attractiveness on employment termination decisions. After viewing a file that contained a poor performance review and a badge with a photograph of an extremely attractive, moderately attractive, or unattractive employee, 178 participants were asked if they would terminate the employee, rated how much they liked the employee, and made a judgment of attribution of her poor performance. Participants were willing to terminate the unattractive woman more frequently than the moderate or extremely attractive women. The participants also liked the unattractive woman less than the others. When asked to rate causes of poor performance, no differences were found based directly on attractiveness, but attributions mediated the relationship between liking ratings and termination decisions.     

Social representations of drugs,causal judgment and social perception

The aim of this study was to analyse the influence of social representation on both social perceptions and social judgments. In the first stage of this study, 47 drug users and 80 ‘normal’ subjects were asked to respond to a questionnaire about representations of drugs. Three weeks later we contacted the same subjects. They were asked to answer some questions about a fictitious story in which an actor labelled as ‘a drug user’ or ‘a person’ disputed with a trader. Three different social representations of drugs were found. It was shown that these social representations were anchored in different social groups which were defined by their proximity to the world of drugs. Subjects who were themselves drug users shared an accepting or an ambivalent social representation of drugs but they also made the most negative judgements about the causes of a fictitious dispute between a trader and a drug addict. Moreover, these subjects had the most negative perception of the drug addict. Furthermore, some factors which increase the salience of social representations were studied. The effect on social perception and causal attributions of the interaction between social representations, the context and personal involvement in drugs was also shown. Some relations between the theory of social representations and the theories about asymmetrical intergroup relationships are exposed.     

注意范围分布对视觉工作记忆巩固过程的影响

以往研究发现个体能够同时巩固一定数量的项目信息进入视觉工作记忆系统。本研究将考察视觉工作记忆的巩固容量是否会受到分配到记忆项目上的注意资源量的影响。实验1在同时序列掩蔽范式的基础上, 用控制记忆项目呈现区域的大小的方法操纵被试的注意范围, 从而达到操纵分配到单个项目上的注意资源量的目的。研究结果显示, 被试的记忆成绩随着注意范围的扩大显著降低, 但在并行和序列呈现条件之间不存在显著差异; 实验2则证实实验1中对注意资源量分配的控制不会影响对项目的知觉编码效率。本研究结果表明, 分配在记忆项目上的注意资源量能够影响记忆巩固的效率, 但不会影响巩固容量。     

The female athletic role as a status determinant within the social systems of high school adolescents

This study examined the relationship between female athletic participation and status attainment within the social status systems of high school adolescents. Although earlier research has consistently demonstrated that the athletic role for males is associated with greatest status within the school, findings regarding the status of female athletes have been contradictory: Some studies have found high status rankings for female athletes while others have revealed negative results. It was therefore argued that current research go beyond the general construct of "female athlete" and consider the type of sport with which the adolescent female is associated as a possible status determinant. Employing a sport typology proposed by Metheny (1967), it was predicted that females associated with sex-appropriate or "feminine" sports (e.g., tennis) would receive significantly higher status ratings than those identified with sex-inappropriate or "masculine" sports (e.g., basketball). One hundred and twenty-one male subjects were asked to indicate which female athlete (associated with a sex-appropriate versus a sex-inappropriate sport) they would most like to date, while 111 female subjects were asked to choose which female athlete they would most like to have as a friend. Chi-square analyses revealed that, as predicted, females associated with sex-appropriate sports were given significantly greater status than females identified with sex-inappropriate sports by both male and female subjects. These results suggest that social assessments made about female sport participation within high school status systems remain heavily influenced by traditional beliefs regarding feminine, "ladylike" behavior.     

Encoding tasks dissociate the effects of divided attention on category-cued recall and category-exemplar generation

The combined effects of encoding tasks and divided attention upon category-exemplar generation and category-cued recall were examined. Participants were presented with pairs of words each comprising a category name and potential example of that category. They were then asked to indicate either (i) their liking for both of the words or (ii) if the exemplar was a member of the category. It was found that divided attention reduced performance on the category-cued recall task under both encoding conditions. However, performance on the category-exemplar generation task remained invariant across the attention manipulation following the category judgment task. This provides further evidence that the processes underlying performance on conceptual explicit and implicit memory tasks can be dissociated, and that the intentional formation of category-exemplar associations attenuates the effects of divided attention on category-exemplar generation.     

靶刺激变换与情景信息属性对真实情景再认的影响

采用眼动研究范式,通过两个实验考察靶刺激变换与情景信息属性对情景再认的影响。实验一结果显示,靶刺激变换对情景再认、靶刺激所属兴趣区的凝视时间均有显著影响,这表明在情景再认过程中,观察者会有意识地搜索靶刺激,靶刺激具有诊断效应;实验二应用了知觉信息与语义信息重合和分离两种情景材料。结果显示,观察者对语义信息的首次注视次数显著多于知觉信息;观察者对知觉信息和语义信息分离条件下语义信息的首次注视时间显著长于重合条件下。这一结果提示,在情景识别过程中,语义信息具有注意优先性,但其优先性会受到知觉信息启动的干扰。     

Children's stereotypes of overweight children

The aim of the present study was to assess the content, favourability and generality of perceptions held about overweight children. The research also addressed whether anti‐fat biases change with age and whether they result from a strong association between overweight and bad behaviour, a weak association between overweight and good behaviour or both. Seventy‐three 5‐ to 10‐year‐olds were read aloud a number of short stories containing characters demonstrating high and low athletic, academic, artistic and social abilities. They were then shown eight different pairs of cards; each pair comprised a drawing of an average‐weight and an overweight version of the same child. Participants were then asked to point to the pictures that looked most like the good and bad characters in the stories. The results demonstrated that 5‐ to 8‐year‐olds were significantly less likely to choose an overweight picture to represent the characters with high athletic, academic, artistic and social ability. In contrast, 9‐ to 10‐year‐olds were significantly less likely to choose an overweight figure to represent the characters with high athletic ability, did not differentiate on the basis of weight for the academic and artistic stories, and were significantly more likely to choose an overweight picture as having high social ability.     

Myopic biases in strategic social prediction: why deadlines put everyone under more pressure than everyone else

Five experiments document biases in the way people predict the outcomes of interdependent social situations. Participants predicted that situational constraints would restrain their own behavior more than it would the behavior of others, even in situations where everyone faced identical constraints. When anticipating the effects of deadlines on outcomes of negotiations, participants predicted that deadlines would hinder their performance more than it would hinder the performance of others. The results shed light on the psychological processes by which people predict the outcomes of and select strategies in strategic social interaction. They extend prior findings, such as people believing themselves to be below average on difficult tasks, to highly interdependent situations. Furthermore, the article shows both how focusing can account for these effects and also how perspective taking can reduce their biasing influence.     

Do individuals with autism and Asperger’s syndrome utilize prior knowledge when pairing stimuli?

While several studies suggest that individuals with autism use prior knowledge appropriately, others have found that this may be a particular area of weakness. The aim of the current study was to investigate whether individuals with autism and Asperger’s syndrome utilize prior knowledge when pairing objects with colours. Participants were presented with cards illustrating common objects and asked to pair them with one of two colour patches. Some target objects were coloured inappropriately (e.g. blue banana), allowing a participant to pair it either with blue or yellow. Results indicated that a majority of participants chose the associated in preference to the surface colour. This suggests that prior knowledge governed pairing in many individuals with autism and Asperger’s syndrome as it did in comparison groups, except in typically developing children aged 5 years. However, those with autism and moderate learning difficulties were less affected by prior knowledge than some of the other groups.     

Recommended Regulation of Common Drugs: The Relative Influence of Facts vs. Labels

The present study examined the hypothesis that individuals are more influenced by a drug name than by the side effects associated with that drug when making recommendations regarding regulation. Subjects recommended the amount of regulation that should exist for eight drugs ranging from aspirin to LSD. One third of the subjects were asked to make recommendations based only on the drug name. Another third made recommendations based only on the facts associated with the drugs (i.e., side effects, symptoms). A final third made recommendations based on both facts and the drug name. Results indicated that, when given only the facts, subjects' recommendations deviated greatly from the actual regulation of the drugs but that the facts were ignored if subjects knew the name of the drug. These results suggest that critical information may be ignored when decisions are made about drug regulation. The implications for self-regulated drug use are discussed.     

The self: Your own worst enemy? A test of the self-invoking trigger hypothesis

The self-invoking trigger hypothesis was proposed by Wulf and Lewthwaite [Wulf, G., & Lewthwaite, R. (2010). Effortless motor learning? An external focus of attention enhances movement effectiveness and efficiency. In B. Bruya (Ed.), Effortless attention: A new perspective in attention and action (pp. 75–101). Cambridge, MA: MIT Press] as a mechanism underlying the robust effect of attentional focus on motor learning and performance. One component of this hypothesis, relevant beyond the attentional focus effect, suggests that causing individuals to access their self-schema will negatively impact their learning and performance of a motor skill. The purpose of the present two studies was to provide an initial test of the performance and learning aspects of the self-invoking trigger hypothesis by asking participants in one group to think about themselves between trial blocks—presumably activating their self-schema—to compare their performance and learning to that of a control group. In Experiment 1, participants performed 2 blocks of 10 trials on a throwing task. In one condition, participants were asked between blocks to think about their past throwing experience. While a control group maintained their performance across blocks, the self group's performance was degraded on the second block. In Experiment 2, participants were asked to practice a wiffleball hitting task on two separate days. Participants returned on a third day to perform retention and transfer tests without the self-activating manipulation. Results indicated that the self group learned the hitting task less effectively than the control group. The findings reported here provide initial support for the self-invoking trigger hypothesis.     

Optimistic metacognitive judgments predict poor performance in relatively complex visual tasks

In some cases, people overestimate how much they can see. This can produce a metacognitive blind spot that may lead participants to devote fewer cognitive resources than a visual task demands. However, little research has tested whether individuals who are particularly optimistic about their visual capabilities are susceptible to poor visual performance. We tested whether optimistic metacognitive judgments would predict poor performance in a visual task, especially when it placed a large attentional load on the participant, and when it required balancing between multiple sources of information. We tested participants in a simplified battle command simulation in which they were asked to detect visual changes. Participants who predicted spatially expansive visual attention performance performed more poorly in the change detection task when the task required tracking larger numbers of aircraft, and when it included a secondary change-list display.     

Why Athletic Doping Should Be Banned

So long as a ban is enforceable, large private athletic institutions—such as Major League Baseball and the National Collegiate Athletic Association—should not allow their athletes to take performance‐enhancing drugs. The argument I present is game‐theoretic: though each athlete prefers unilateral permission to dope over a universal ban, he also prefers a universal ban over universal permission to dope. That is because, while doping improves absolute measures of performance, it does not improve relative performance if many athletes dope. Large private athletic institutions should honour their athletes' preferences and should not enact any policy that gives only some athletes but not others permission to dope. Thus, they should ban doping. My paper examines and defends this game‐theoretic argument. After explaining the argument, I compare it (favourably) to other arguments for the same conclusion. I then discuss whether the game‐theoretic argument counterintuitively fails to justify banning some forms of doping (no), and whether it counterintuitively justifies banning things other than doping (also no). After arguing that a doping ban on game‐theoretic grounds is neither wrongly paternalistic or nor wrongfully coercive, I end by discussing some limitations of the argument.
