Chronic amphetamine exposure during the preweanling period does not affect avoidance learning or novelty-seeking of adult rats

The purpose of the present study was to determine whether exposure to amphetamine during the preweanling period would impact the learning or reward processes of rats tested in adulthood. In three experiments we examined whether amphetamine treatment (0-10 mg/kg per day) on postnatal days 11-17 altered the subsequent performance of adult Sprague-Dawley rats on a step-down passive avoidance, active avoidance, or novelty-seeking task. There was no evidence that postnatal amphetamine exposure affected performance on any of these tasks. These results suggest that the long-term impact of pre- and postnatal psychostimulant exposure differs, because in utero stimulant treatment is known to produce learning deficits and decrease reinforcement efficacy of rats tested in adulthood.     

Intrinsic religiosity reduces intergroup hostility under mortality salience

Results of three studies indicate that intrinsic religiosity and mortality salience interact to predict intergroup hostility. Study 1, conducted among 200 American Christians and Jews, reveals that under mortality salience, intrinsic (but not extrinsic or quest) religiosity is related to decreased support for aggressive counterterrorism. Study 2, conducted among 148 Muslims in Iran, demonstrates that intrinsic religiosity predicts decreased out‐group derogation under mortality salience. Study 3, conducted among 131 Polish Christians, shows that under mortality salience, priming of intrinsic religious concepts decreases support for aggressive counterterrorism.

Religious polarization: contesting religion in secularized Western European countries

In light of recent claims about increasing religious polarization in secularized countries, we study the extent to which the non-religious contest religion in Western European countries and whether and how the Protestant and Catholic heritage of these countries plays a role in this. Analyzing data from the International Social Survey Program (ISSP 1998 and 2008) data by means of multilevel analysis, we demonstrate that religious polarization is stronger in the most secularized countries and in countries with a Catholic religious heritage. Moreover, in secular countries, polarization stems from religious fervency, whereas in countries with a Catholic heritage, it stems from anti-religious fervency.     

Assessing Emotional Abuse Victimization and Perpetration: A Multi-Theoretical Examination

Criminological theories traditionally used to account for crime and deviance have now been applied to explain physical intimate partner violence (IPV). However, little research has examined whether these theories can also account for emotional abuse victimization and perpetration in intimate relationships. Such an endeavor is important because one important requirement for evaluating theory is the exploration of core propositions with different types of behaviors and, of course, testing this social problem in a theoretical lens will inform health professionals and others to identify correlates that may help them create preventative solutions to reduce or end this problem. Therefore, the purpose of this study is to examine the efficacy of self-control, social learning, and strain theories to explain emotional abuse victimization and perpetration. Using a sample of college students from two public universities (N = 434), results show variables derived from general strain theory better predicted emotional abuse victimization and perpetration than self-control or social learning. Limitations, as well as directions for future research, are discussed.     

Developing Norms of Argumentation: Metacognitive,Epistemological, and Social Dimensions of Developing Argumentive Competence

We examine how extended engagement in argumentation with peers leads to enhanced metalevel understanding of argumentive discourse. Following such engagement, young adolescents demonstrated enhanced understanding of counterargument and use of evidence as objectives of skilled argumentation, relative to a nonparticipating comparison group. Among the participating group, analysis of metatalk (talk about the discourse, distinguished from talk about the topic) during electronic peer dialogs proved revealing regarding participants’ evolving awareness of and adherence to discourse norms. Metatalk became more reciprocal and sustained with time and revealed an increasing focus on the argumentation process and engagement in talk that seeks to direct it. Implications are considered for understanding and studying argumentation as a social practice that encompasses not only individual skills but also the less visible norms that govern it and that members of a social group come to share.     

Exploring the Boundaries of Sublexical Word Identification Units: The Use of Onsets and Rimes and Reading Ability

Four priming experiments investigating the functional use of onsets and rimes as identification units in normally and poorly reading children, matched on reading age level, are reported. Experiments 1 (onsets) and 2 (rimes) used monosyllabic words. High- and low-frequency bigram letter clusters were primed. Primes turned out to be more effective when they coincided with the rimes of target words then when they did not. For onsets this was not the case. The effect of priming was stronger in low-frequency letter clusters. For rime units there was a significant prime by rime coincidence interaction, consistent with data presented by Bowey (1990). A differential effect of rime priming was obtained for the ability groups in high-frequency letter clusters. Only in the normal reader control group were response latencies negatively affected by noncoinciding primes in high-frequency rime units. This finding suggests that these subjects probably had better access to letter information in the final part of words. In Experiments 3 (onsets) and 4 (rimes) bisyllabic compound nouns were used. Elements of the second syllable were used as primes. Main group effects were found in both experiments, but the effects obtained with monosyllabic words were not replicated. It is concluded that onset/rime mechanisms primarily operate within the boundaries of monosyllabic words and/or in stressed syllables.
