The instrumental rationality of addiction

The claim that non-addictive drug use is instrumental must be distinguished from the claim that its desired ends are evolutionarily adaptive or easy to comprehend. Use can be instrumental without being adaptive or comprehensible. This clarification, together with additional data, suggests that Müller & Schumann's (M&S's) instrumental framework may explain addictive, as well as non-addictive consumption.     

A comparative assessment of the factor structures and psychometric properties of the GHQ-12 and the GHQ-20 based on data from a Finnish population-based sample

The General Health Questionnaire (GHQ) is a self-report questionnaire designed to identify psychological distress. Psychometric properties of two versions of GHQ-12 and GHQ-20 were assessed in a large population-based sample of Finnish twins, ages 22 to 27 (n= 4580). Participants were randomized into two subgroups, namely Twin1 (n= 2294) and Twin2 (n= 2286). The GHQ-12 data were assessed using Confirmatory Factor Analysis (CFA). The factor structure of the GHQ-20 was first assessed with Exploratory Factor Analysis (EFA) in the Twin1 dataset, and the results obtained were then subjected to CFA in Twin1 and Twin2 datasets. The CFA of the GHQ-12 indicated that the best fit and the simplest solution were provided by the three-factor solution in both subpopulations. Analyses of the GHQ-20 suggested that the four-factor structure was superior to the three-factor model. This result is also theoretically justifiable. Compared to the 12-item version, GHQ-20 provides additional fourth factor of anhedonia, suggesting some discriminative power.     

To know you is to love you: Effects of intergroup contact and knowledge on intergroup anxiety and prejudice among indigenous Chileans

Two surveys were conducted in Chile with indigenous Mapuche participants (N study 1: 573; N study 2: 198). In line with previous theorising, it was predicted that intergroup contact with the non‐indigenous majority reduces prejudice. It was expected that this effect would be because of contact leading to more knowledge about the outgroup, which would then lead to less intergroup anxiety. The two studies yielded converging support for these predictions.     

Effects of Vocabulary and Phonotactic Probability on 2-Year-Olds’ Nonword Repetition

This study investigates the relationship between nonword repetition (NWR) and vocabulary in 2-year-olds. Questions addressed are whether (1) NWR and vocabulary are associated, (2) phonotactic probability affects NWR, and (3) there is an interaction effect between phonotactic probability and vocabulary on NWR performance. The general aim of the study is to investigate whether NWR, as a task of phonological storage, assesses the quality of phonological representations in children as young as 2 years of age. 557 Dutch 2-year-olds performed a NWR task containing items of varying phonotactic probability as well as a receptive vocabulary task. The results showed a moderate, significant correlation between NWR and vocabulary. Phonotactic probability had an effect on NWR performance. Further analyses showed that there was a significant interaction between phonotactic probability and vocabulary for part of the items. These results support previously reported effects of vocabulary and phonotactic probability on NWR in older, English-speaking children for a large sample of Dutch-speaking 2-year-olds, and provide evidence that NWR assesses the quality of phonological representations already in very young children.     

Some considerations about the biological appearance of pacing stimuli in visuomotor finger-tapping tasks

Sensorimotor synchronization is a crucial function for human daily activities, which relies on the ability of predicting external events. Synchronization performance, as assessed in finger-tapping (FT) tasks, is characterized by an anticipation tendency, as the tap generally precedes the pacing event. This synchronization error (SE) depends on many factors, in particular on the features of the pacing stimulus. Interest is growing in the facilitation effect that action observation has on motor execution. So far, neuroimaging and neurophysiology studies of motor priming via action observation have mainly employed tasks requiring single action instances. The impact of action observation on motor synchronization to periodic stimuli has not yet been tested; to this aim, a synchronization FT task may be an eligible probing task. The purpose of this study was to characterize a biological pacer at the behavioral level and provide information for those interested in studying the brain processes of continuous observation/execution coupling in timed actions using FT tasks. We evaluated the influence of the biological appearance of a pacer (a tapping finger) on SE, when compared to an abstract, kinematically equivalent pacer (a tilting hinged bar) and a more standard stimulus (a pulsating dot). We showed that the continuous visual display of a biological pacer yields comparable results to the abstract pacer, and a more robust performance and larger anticipations than a traditional pulsating stimulus.     

Choice of comparisons in intergroup settings: the role of temporal information and comparison motives

Three studies investigated comparison choices in intergroup settings, a neglected but important topic for theories of intergroup relations. Two main questions were addressed: What is role of comparison motives in determining comparison choices in intergroup contexts? How important are temporal comparisons (of the ingroup in the past or future) in intergroup settings? In Study 1 (N = 115), motives for Assessment or Enhancement were primed in a multi‐group performance context. Compared to Controls, Assessment priming encouraged both upward and downward comparisons, while Enhancement encouraged mainly downward comparisons. In general, temporal comparisons were as prevalent as comparisons with other groups. Study 2 (N = 199) employed a real‐world setting in which members of a mid‐ranking university indicated their interest in comparing with other higher or lower status universities or with their own university in the past. Temporal comparisons were once more much in evidence, and manipulating enhancement motives again encouraged downward comparisons. In Study 3 (N = 40), set in the context of inter‐nation student comparisons, Improvement motives were primed implicitly. This led to an increase in interest in an outgroup just above the ingroup but to a decrease in interest in future‐oriented comparisons. Copyright © 2006 John Wiley & Sons, Ltd.     

“Casting off the coat of Konrad”: Polish intelligentsia in the era of system transformation

This article outlines the means of adaptation by the Polish intelligentsia to the conditions of a free-market (capitalist) system. The ethos of the Polish intelligentsia is at a fundamental level in conflict with the ethos of the middle class. Research conducted in the 1990s into social stratification in Poland clearly showed that it was the intelligentsia that was claiming the best new employment positions that “opened up” along with the market and democracy. Nonetheless, sociologists consider changes in consciousness to be phenomena belonging to the so-called longue durée. For this reason, it has been useful to show how the beneficiaries of the new system are handling the order of norms and values that, while subject to reconstruction, has clear consequences at the level of lifestyle, way of thinking, and means of constructing one’s own biography.
