Implicit or non-conscious cognition is traditionally assumed to be robust to pathology but Gomez-Beldarrain et al. recently showed deficits on a single implicit task after head injury. Laboratory research suggests that implicit processes dissociate. This study therefore examined implicit cognition in 20 head-injured patients and age- and IQ-matched controls using a battery of four implicit cogn...

Although the effects of negative stereotypes and observer pressure on athletic performance have been well researched, the effects of positive stereotypes on performance, particularly in the presence of observers, is not known. In the current study, White males watched a video either depicting Whites basketball players as the best free throwers in the NBA (positive stereotype), Black basketball ...

Americans stereotype elderly people as warm and incompetent, following from perceptions of them as noncompetitive and low status, respectively. This article extends existing research regarding stereotyping of older people in two ways. First, we discuss whether the mixed elderly stereotype is unique to American culture. Data from six non-U.S. countries, including three collectivist cultures, dem...

The purpose of the current study was to investigate the role of interactivity (the use of pen and paper) in defusing the impact of stereotype threat on difficult mental arithmetic tasks, covering all four operations of mathematics. Eighty-four 16-year-old girls from secondary schools in South East England (UK) participated in this study. Participants carried out (in an educational setting) diff...

In 4 studies the authors compared the effect of exemplars that deviate from the prototype in one or the other direction while controlling for the absolute amount of deviance. Incongruent exemplars typically do not change a stereotype. Yet, it is unclear whether this is also the case with exemplars that are more extreme than the stereotype, named supercongruent hereafter. Within Study 1 the auth...

The authors tested and confirmed the hypothesis that priming a stereotype or trait leads to complex overt behavior in line with this activated stereotype or trait. Specifically, 4 experiments established that priming the stereotype of professors or the trait intelligent enhanced participants' performance on a scale measuring general knowledge. Also, priming the stereotype of soccer hooligans or...

The person perception literature has shown that negative information on warmth influences impression formation more than other kinds of information. In the present paper, we argue for the usefulness of using the knowledge accumulated on the negativity effect on warmth when studying how members of a group who are disconfirming the group stereotype are perceived. We show that negative divergent i...

Stereotype threat occurs when negative stereotypes about group performance on a particular task are made salient, thereby negatively affecting group member performance. Specifically, research has demonstrated that stereotype-threatened women underperform on tests of mathematical ability (Spencer, Steele, & Quinn, 1999). A possibility for reducing stereotype threat in women was explored by havin...

This experiment examined the eVects of implicit gender-math stereotyping and implicit gender and math identiWcation on women’s math performance under stereotype threat and reduced threat conditions. Results showed that of the three, only implicit gender-math stereotyping moderated stereotype threat eVects on women’s math performance: women who showed less implicit math-gender stereotyping showe...

Distributed systems are increasingly built using distributed object or component middleware. The dynamic behaviour of those distributed systems is influenced by the particular combination of middleware synchronisation and threading primitives used for communication amongst distributed objects. A designer may accidentally choose combinations that cause a distributed application to enter undesira...
