La performance des élèves des communautés noires aux examens ministériels du secondaire Québécois: Cohortes 1994, 1995, 1996

This article discusses the results of various sub-groups of Quebec students from the Black community (originating from the West Indies or Africa and having French, English or Creole as their maternal language) who started high-school in the French or English sector in 1994, 1995 or 1996, on various departmental exams: history, physical sciences, written French and written English, language of instruction or second language, depending on the sector. The authors begin by presenting the socio-demographic, educational, and socio-economic profile of the population under study. The performance of the various sub-groups within each sector is then discussed and certain elements are put forward to explain the differences encountered. Finally, the authors add some concluding remarks about the potential contribution of the research, especially as it regards the identification of factors influencing schooling outcomes of visible minorities, both in Quebec and in other Canadian provinces.     

Guns, testosterone, and aggression: an experimental test of a mediational hypothesis

We tested whether interacting with a gun increased testosterone levels and later aggressive behavior. Thirty male college students provided a saliva sample (for testosterone assay), interacted with either a gun or a children's toy for 15 min, and then provided another saliva sample. Next, subjects added as much hot sauce as they wanted to a cup of water they believed another subject would have to drink. Males who interacted with the gun showed significantly greater increases in testosterone and added more hot sauce to the water than did those who interacted with the children's toy. Moreover, increases in testosterone partially mediated the effects of interacting with the gun on this aggressive behavior.     

A multicultural study of stereotyping in English-speaking countries

Citizens of 9 different English-speaking countries (N = 619) evaluated the average, or typical, citizen of 5 English-speaking countries (Great Britain, Canada, Nigeria, United States, Australia) on 9 pairs of bipolar adjectives. Participants were drawn from Australia, Botswana, Canada, Kenya, Nigeria, South Africa, the United States, Zambia, and Zimbabwe. There were statistically significant similarities in the rankings of the 5 stimulus countries on 8 of the 9 adjective dimensions and a strong convergence of autostereotypes and heterostereotypes on many traits. The results relate to previous stereotyping research and traditional methods of assessing the accuracy of national stereotypes.     

Who Do We Tell and Whom Do We Tell On? Gossip as a Strategy for Status Enhancement1

College students ranked the interest value of 12 different gossip scenarios; likelihood of spreading the gossip; and the people to whom they would be most likely to tell the gossip, depending on whether the gossip was about male or female professors, relatives, friends, acquaintances, strangers, or a same‐sex rival or a romantic partner. Damaging, negative news about rivals and positive news about friends and lovers was especially prized and likely to be passed on. Aside from romantic partners, males and females were more interested in information about same‐sex others than about opposite‐sex others. Overall, men were most likely to confide in their romantic partners, but females were equally likely to share gossip with their lovers and their same‐sex friends.     

Dissociating expectancy of shock and changes in skin conductance: an investigation of the Perruchet effect using an electrodermal paradigm

Is human Pavlovian conditioning driven by a unitary, propositional system (as claimed by Mitchell, De Houwer, & Lovibond, 2009) or by dual systems; one under conscious control, symbolic in nature, and requiring effort to deploy, and the other utilizing associative processes and automatic in its operation (McLaren, Green, & Mackintosh, 1994)? Past research has suggested that for electrodermal conditioning to occur in humans, conscious awareness of the contingencies is necessary to produce conditioned responding (e.g., Hinchy, Lovibond, & Ter-Horst, 1995), as predicted by single process theories that attribute the conditioned response (CR) to conscious expectancy of the shock. In this article, the authors examined the Perruchet effect (Perruchet, 1985), using an electrodermal paradigm to determine whether there is any role for associative processes in human electrodermal conditioning. The authors attempted to replicate the basic effect, whereby expectancy of an unconditioned stimulus (US) increases over a run of nonreinforced trials while the CR to the conditional stimulus (CS) declines, and the complementary pattern in which expectancy decreases over a run of reinforced trials while the CR to the CS grows in strength. In line with these patterns, the change in skin conductance response (our CR) as a function of US run length was found to follow a linear trend opposite to that of conscious expectancy of shock with respect to US run length. This dissociation supports a dual-processing system account of human Pavlovian conditioning, with conscious, controlled processes governing expectancy (and subject to the gambler's fallacy), whereas automatic, associative processes determine at least some of the strength of the CR to the CS.     

Of Tabloids and Family Secrets: The Evolutionary Psychology of Gossip1

Two experiments tested hypotheses about gossip derived from an evolutionary perspective. In the first experiment, 128 people ranging in age from 17 to 62 years ranked the interest value of 12 tabloid stories about celebrities differing in age and gender. In the second experiment, 83 college students ranked the interest value and likelihood of spreading gossip about male or female professors, relatives, friends, acquaintances, or strangers based on 12 different gossip scenarios. The results of these experiments confirmed a consistent pattern of interest in gossip marked by a preference for information about others of the same age and gender. Exploitable information in the form of damaging, negative news about nonallies and positive news about allies was especially prized and likely to be passed on. The findings confirm that gossip can serve as a strategy of status enhancement and function in the interests of individuals, and that it does not just function as a means of social control within groups.
