Is the devil in the detail? Evidence for S-S learning after unconditional stimulus revaluation in human evaluative conditioning under a broader set of experimental conditions

Whether valence change during evaluative conditioning is mediated by a link between the conditional stimulus (CS) and the unconditional stimulus (US; S-S learning) or between the CS and the unconditional response (S-R learning) is a matter of continued debate. Changing the valence of the US after conditioning, known as US revaluation, can be used to dissociate these accounts. Changes in CS valence after US revaluation provide evidence for S-S learning but if CS valence does not change, evidence for S-R learning is found. Support for S-S learning has been provided by most past revaluation studies, but typically the CS and US have been from the same stimulus category, the task instructions have suggested that judgements of the CS should be based on the US, and USs have been mildly valenced stimuli. These factors may bias the results in favour of S-S learning. We examined whether S-R learning would be evident when CSs and USs were taken from different categories, the task instructions were removed, and more salient USs were used. US revaluation was found to influence explicit US evaluations and explicit and implicit CS evaluations, supporting an S-S learning account and suggesting that past results are stable across procedural changes.     

Cognitive complexity effects in perceptual classification are dissociable

It has been proposed that a procedural-based classification system mediates the learning of information-integration categories, whereas a hypothesis-testing system mediates the learning of rule-based categories. Ashby, Ell and Waldron (2003) provided support for this claim by showing that a button switch introduced during classification transfer adversely affected information-integration but not rule-based performance. Nosofsky, Stanton and Zaki (2005) showed that increasing "cognitive complexity" can lead to button switch costs on rule-based performance. They argue that "cognitive complexity," and not the existence of separable classification systems, accounts for Ashby et al.'s empirical dissociation. The present study shows that experimental manipulations that increase "cognitive complexity" often have dissociable effects on information-integration and rule-based classification that are predicted a priori from the processing characteristics associated with the procedural-based and hypothesis-testing systems. These results suggest that manipulations of "cognitive complexity" can be dissociated, suggesting that "cognitive complexity" in not a unitary construct that affects a single psychological process.     

How children narrate happy and sad events: does affective state count?

The influence of induced affective states on children's narratives of personal events was investigated. The affective state of 5‐to‐6‐year‐old children, 128 in number, was manipulated by way of winning or losing a game. They were then asked to narrate happy or sad personal events. A self‐report instrument indicated that a different affective state was indeed induced by the two game conditions. Narratives were coded for agency, affective aspects and structural complexity (antecedents). The negative condition influenced attribution of causality and intention to agent and addressee, according to a self‐serving bias and affected number of antecedents. Moreover, in the negative condition, global intensity revealed a congruency effect, in line with the Affect Infusion Model. However, mental states varied with event valence, independent of affect‐inducing condition. Results are discussed in terms of the complexity of the relation between emotional event narratives and children's affective state. Copyright © 2007 John Wiley & Sons, Ltd.     

Rorschach Comprehensive System data for a sample of 343 adults from Finland

This article combines Rorschach Comprehensive System (CS; Exner, 1990, 1993) data from four projects conducted in Finland between 1990 and 1995. The projects studied a stratified random sample of Finnish nonpatients, a cohort of twins, a group of elderly men, and a random sample collected to investigate sleep difficulties. The 343 records from these four studies provide a representative survey of Rorschach responding throughout the Finnish population.     

School track and ethnic classroom composition relate to the mainstream identity of adolescents with immigrant background in Germany,but not their ethnic identity

Although developing a cultural identity is a core task for adolescents from immigrant families and the school is a highly important context in adolescence, to date, few studies have examined whether adolescents with particular cultural identities cluster in certain school contexts. Using data from a representative German sample including 7702 secondary school students of immigrant background from 1643 classrooms, we examined how the attended school track and four aspects of ethnic classroom composition relate to adolescents' cultural identity (i.e., their ethnic identity and mainstream identity). Two-level structural equation models indicated that students' ethnic identity was not systematically associated with the attended school track and the ethnic composition of the classroom. However, attending the academic school track, a classroom with a low proportion of classmates with immigrant background and frequently using German with classmates related positively to mainstream identity. Ethnic diversity and proportion of co-ethnics in class did not relate to mainstream identification. Our findings suggest that the ethnic identity of adolescents with an immigrant background in Germany is largely independent from the different socialisation contexts related to school tracks and the ethnic classroom composition. Yet, students' with a strong mainstream identity cluster in certain school contexts.     

Response to Richard B. Miller's "Children, Ethics, and Modern Medicine"

In this essay, Paul Lauritzen examines Richard B. Miller's liberal account of pediatric ethics by asking if the duty to promote a child's basic interests is substantial enough to secure the well‐being of children. This question is raised in light of two case studies: daytime TV talk shows that broadcast interviews with sexually active children, and a medical study conducted to test the effect of growth hormone treatment on adult height in peripubertal children. In both cases, Lauritzen argues, children are subjected to potential harms that are not easily explained, and therefore not easily prevented, by appeals to basic interests.     

A Cluster of Suicides at a London Psychiatric Unit

In an epidemiologically based study, a spate of 14 suicides among current patients of a London psychiatric unit was investigated. Statistical analysis showed it to be a discrete cluster of suicides, rather than a chance occurrence. There was no evidence of direct linkage or “contagion” between the suicides. Thirteen of the patients suffered from severe, chronic mental illness and all but 2 had been known to the psychiatric unit for at least a year. Twelve used violent methods, in 8 cases jumping from a high place. Although no definite cause for the cluster could be established, it coincided with a period of uncertainty concerning the future of the hospital and with changes in and absenteeism of senior medical staff.     

A self-determination theory approach to problematic drinking and intimate partner violence

Problematic drinking has long been established as an important antecedent to the perpetration of intimate partner violence (IPV). As little research has evaluated individual differences beyond anger in this association, this research examines problematic drinking and IPV perpetration through the lens of self-determination theory (SDT), the relational perspective suggesting individuals are motivated to be in their relationship for autonomous (i.e., self-driven) and controlled (i.e., guilt-driven) reasons. We test the hypothesis that problematic drinking is more strongly associated with IPV among those who are controlled in their motivation in four independent samples (N?=?617). College students in relationships completed measures of alcohol consumption, negative alcohol-related consequences, relationship motivation, and IPV perpetration. Results generally suggested that the association between both alcohol consumption and negative alcohol-related consequences and IPV perpetration is only significant among those endorsing greater controlled motivation. This study supports problematic drinking as not being an equal risk factor for all individuals, and suggests that some people may be more vulnerable to problematic drinking resulting in relationship aggression.
