Accepting Muslim minority practices: A case of discriminatory or normative intolerance?

West European societies have seen strong debates about the acceptance of Muslim minority practices. In the current research we sought to better understand intolerance by examining whether people use a double standard in which the same practices are tolerated of Christians but not of Muslims (discriminatory intolerance), or rather reject the practices independently of the religious minority group because these are considered to contradict society's normative ways of life (normative intolerance). The results of two survey‐embedded experiments among native Dutch were most in agreement with an interpretation in terms of normative intolerance rather than discriminatory intolerance. This suggests that the rejection of Muslim practices has less to do with Muslims per se but rather with the perceived normative deviance of the practices, independently of the religious minority group. These findings broaden the research on anti‐Muslim sentiments and thereby the debate on the place of Islam within Western liberal societies.     

Abnormalities of visual evoked potentials by checkerboards in children with specific reading disability

Visual evoked potentials by checkerboards of varying check sizes were recorded in the two hemispheres of 16 specific reading disabled and 8 normal children. In most of the disabled subjects a gross hemisphere asymmetry was assessed, while in the control group the usual evoked potential symmetry was observed. In some disabled subjects the evoked potentials had a larger amplitude in the right hemisphere, while in others the amplitude was larger in the left hemisphere. In a small subgroup the evoked potentials were symmetrical, but they had a smaller amplitude than in the control subjects. The results, giving evidence of a dysfunction in basic visual processing, are discussed in the context of current literature on clinical subgroups and the interhemispheric relationship in the dyslexic syndrome.     

Contraction: On the Decision-Theoretical Origins of Minimal Change and Entrenchment

We present a decision-theoretically motivated notion of contraction which, we claim, encodes the principles of minimal change and entrenchment. Contraction is seen as an operation whose goal is to minimize loses of informational value. The operation is also compatible with the principle that in contracting A one should preserve the sentences better entrenched than A (when the belief set contains A). Even when the principle of minimal change and the latter motivation for entrenchment figure prominently among the basic intuitions in the works of, among others, Quine and Ullian (1978), Levi (1980, 1991), Harman (1988) and Gärdenfors (1988), formal accounts of belief change (AGM, KM – see Gärdenfors (1988); Katsuno and Mendelzon (1991)) have abandoned both principles (see Rott (2000)). We argue for the principles and we show how to construct a contraction operation, which obeys both. An axiom system is proposed. We also prove that the decision-theoretic notion of contraction can be completely characterized in terms of the given axioms. Proving this type of completeness result is a well-known open problem in the field, whose solution requires employing both decision-theoretical techniques and logical methods recently used in belief change.     

Treatment seeking for posttraumatic stress in Israel Defense Forces veterans deployed in the Second Lebanon War (2006) and “Operation Cast Lead” in the Gaza Strip (2009): a comparative study

Background and objectives: The goal of the study was to determine the long-term prevalence of combat-related treatment seeking and posttraumatic stress disorder (PTSD) in Israel’s veterans deployed to the Second Lebanon War (2006) and “Operation Cast Lead” in the Gaza Strip (2009).

Methods: The prevalence of treatment seeking and DSM-IV-TR diagnoses among Israel Defense Force (IDF) veterans was assessed using seven and five year’s surveillance and records. The whereabouts and combat exposure of veterans during the war was determined based on the IDF’s Operations Directorate records.

Results: Overall prevalence of treatment seeking was 1.32% and 0.38% in the Second Lebanon War and “Operation Cast Lead”, respectively. The prevalence of treatment-seeking veterans from the Second Lebanon War and in “Operation Cast Lead” was significantly higher in soldiers deployed to high combat-exposure zones (2.19% and 3.1%, respectively), relative to low combat-exposure zones (0.24% and 0.06%, respectively), and relative to soldiers deployed elsewhere (0.26% and 0.02%, respectively). PTSD prevalence was similar among treatment-seeking veterans deployed in high combat-exposure zones in both combats.

Conclusions: There is a gap of anywhere between 3% and 11% between treatment seeking by IDF veterans following war deployment and the actual prevalence of PTSD in this soldier population.     

Being tolerated: Implications for well-being among ethnic minorities

Tolerating or condoning practices that one finds objectionable is typically considered a positive way to negotiate intergroup differences. However, being the target of tolerance might harm well-being, which we examined in three studies (a survey and two experiments) among a total of 1,054 members of various racial/ethnic minority groups in the United States. In Study 1, we found that perceiving oneself to be tolerated on the basis of one’s ethnic group membership was associated with more negative well-being. In Study 2, we found that bringing to mind experiences of being tolerated results in less positive and more negative affect than thinking about experiences of acceptance, but more positive and less negative outcomes than thinking about overt discrimination experiences. In Study 3, we replicated the results of Study 2 while demonstrating that threat to social identity needs mediates the tolerance–well-being link. These results suggest that being tolerated is related to minority targets’ well-being in ways that are intermediate between being treated with outright discrimination and full acceptance, but that being tolerated follows a pattern closer to discrimination.     

Anger arousal,deindividuation, and aggression

We tested the notion that angered persons' aggression would be increased through a process of excitation transfer when they are deindividuated, but that individuated subjects would be most aggressive in circumstances under which they could use the information that they had ingested an arousing drug as a pretext for their aggression. Sixty-two male undergraduates participated under either deindividuated or individuated conditions, ingested either 350 mg of caffeine or a placebo, were informed that they had either taken a stimulant or a nonarousing drug, and were all angered by a confederate. According to prediction, when deindividuated and aroused by caffeine the amount of noxious stimulation subjects delivered to the provocateur was greater if they believed that the drug they had taken was nonarousing than if they thought it was a stimulant; in contrast, individuated subjects' aggression was greater when aroused subjects believed the drug was a stimulant. The results are discussed in terms of excitation transfer and the effect of aggression inhibition on the use of information about one's arousal.     

The perceived strength of illusory contours

Illusory contours are not well understood, partially because a lack of physical substance complicates their specification via physical standards. One solution is to gauge illusory contours with respect to luminance-defined contours, which are easily quantified physically. Accordingly, we chose a metric (perceived contrast) that expresses illusory contour strength in terms of the physical contrast of luminance-defined contours. Using this metric, adult observers adjusted the contrast of a luminance-defined contour until it matched the perceived contrast of an illusory contour. Illusory contour length, inducer size, and inducer contrast all influenced illusory contour strength.. The results are adequately explained via low-level visual processes. It appears that matching paradigms can be beneficial in quantitative studies of illusory contours.
