Cavernous angioma within an olfactory groove meningioma. Case report.

The authors present the case of a 60-year-old woman who was admitted to their institution after suffering a subarachnoid hemorrhage (SAH). Neuroimaging data demonstrated an olfactory groove meningioma surrounded by a slight edema, but there was no evidence of SAH, although results of the lumbar puncture demonstrated xanthochromic cerebrospinal fluid. Angiography confirmed the diagnosis of meningioma, but results of magnetic resonance imaging led the authors to suspect a cavernoma within the meningioma. This diagnosis was established by pathological examination of the resected lesion. The patient did well and was discharged soon after surgery. This very rare association and the propensity of each of these lesions to be revealed by hemorrhage are discussed.

Prejudice on the stage: self-monitoring and the public expression of group attitudes.

According to self-monitoring theory (Snyder, 1987), high self-monitors tailor their self-presentation for the sake of desired public appearances, whereas low self-monitors are relatively unlikely to practice such situationally guided impression management strategies. It was therefore predicted that, when asked to publicly express their attitudes regarding a social group, high self-monitors would modify their expressive behaviour in a direction consistent with the attitudes attributed to their audience. Conversely, low self-monitors would be unaffected by their audience's attitude towards this group. A study was conducted to test this hypothesis: participants, whose level of self-monitoring and prejudice towards homosexuals had been previously measured, were asked to report their thoughts regarding this group in an open-ended manner. They anticipated discussing these thoughts with an audience perceived as either prejudiced or tolerant, or they expected that their responses would remain private. In line with predictions, high self-monitors expressed more prejudice when the audience was perceived as prejudiced than tolerant, whereas low self-monitors were not affected by the audience's attitude.

When group representations serve social change: the speeches of Patrice Lumumba during the Congolese decolonization.

This article examines how group representations can be used strategically to induce social change. The speeches delivered by Patrice Lumumba during the decolonization of the Belgian Congo were analysed using the content analysis software ALCESTE. Lumumba used radically different descriptions of Belgians and Congolese depending on the period during which the speech was delivered and on the audience he was addressing (Congolese or Belgian). When addressing Belgians, he described their countrymen as benevolent allies who could assist the development of Congo, and the Congolese as pacific and friendly. When addressing Congolese audiences, Belgians were described as oppressors, and Congolese as victims. In addition he emphasized the unity of the country more at the end of the decolonization process than at its onset. Considering that his nationalist and pan-African aims remained stable, we suggest that this variability stems from the different actions expected from his audiences, as a function of their group membership and the political context. We argue that this performative dimension cannot be captured if group representations, including stereotypes, are only viewed in cognitive terms. In addition, we show that they should be studied not only as justifications for the existing social order but also as instruments of social change.

On the role of familiarity with units of measurement in categorical accentuation: Tajfel and Wilkes (1963) revisited and replicated.

The present article provides evidence for the role of participants' familiarity with units of measurement in categorical accentuation with unidimensional physical estimates. Belgian and American participants estimated the lengths of lines varying in length. Depending on the condition, the lines were or were not systematically associated with categorical labels, and the estimates were made either in inches or in centimeters. Consistent with our predictions, (a) categorical accentuation was higher when the lines were systematically categorized than when they were not, and (b) this effect was stronger when participants reported their estimates in an unfamiliar measurement unit (i.e., Belgian participants using inches, and American participants using centimeters). These findings support the view that people's reliance on categorical information is more likely to emerge given uncertain contexts of judgment. Additionally, they may help explain why researchers have had difficulties replicating the categorical accentuation effect in the past.
