External thought—does sketching assist problem analysis?

An experimental study (n = 60 students) tests the advantages of being allowed to sketch a representation of a mechanical system (involving components such as weights, ropes and pulleys) when one is to be subsequently asked questions about this system. In comparison to a control group who were not allowed to sketch the system, the main advantages of sketching were found to be a reduction in the perceived difficulty of the problems and an increase in the likelihood of correctly inferring relations between the components. These advantages came at no extra cost in terms of additional time being needed to analyse the situation or solve the problems. However, sketching conferred no advantage in terms of the correct recall of system components. Copyright © 2004 John Wiley & Sons, Ltd.     

Learning from implicit learning literature: Comment on Shea, Wulf, Whitacre, and Park (2001)

In their analysis of complex motor skill learning, Shea, Wulf, Whitacre, and Park (2001) have overlooked one of the most robust conclusions of the experimental studies on implicit learning conducted during the last decade--namely that participants usually learn things that are different from those that the experimenter expected them to learn. Weshow that the available literature on implicit learning strongly suggests that the improved performance in Shea et al.'s Experiments 1 and 2 (and similar earlier experiments, e.g., Wulf & Schmidt, 1997) was due to the exploitation of regularities in the target pattern different from those on which the postexperimental interview focused. This rules out the conclusions drawn from the failure of this interview to reveal any explicit knowledge about the task structure on the part of the participants. Similarly, because the information about the task structure provided to an instructed group of participants in Shea et al.'s Experiment 2 did not concern the regularities presumably exploited by the standard, so-called implicit, group, Shea et al.'s claim that explicit knowledge may be less effective than implicit knowledge is misleading.     

A social psychological perspective on World War II collaboration in the 21st century: A Belgian case

The present study addresses antecedents and consequences of attitudes towards collaboration in the context of World War II (WWII) in Belgium. A survey conducted on 922 Belgian French- and Dutch-speaking participants shows that, on overall, Dutch-speakers perceive collaboration as more moral and support amnesty of the former collaborators at a higher level than their Francophone counterparts. In addition, we show that these attitudes are predicted by the generational belonging, linguistic and national identification of the participants. Finally, we find that attitudes towards WWII collaboration are linked to specific political prospects for the future of the country only among Dutch-speakers. These findings suggest that, 75 years after its end, the issue of collaboration during WWII still divides the Belgian society. Furthermore, they underline the added value of a multilevel approach in the understanding of social psychological phenomena.     

Self-dehumanisation in severe alcohol use disorder: Links with self-stigma and environmental satisfaction

Metadehumanisation (i.e., the perception of being considered as less than human by others) is proposed to be widespread in stigmatised populations, such as people with severe alcohol use disorder (SAUD). However, the relations between metadehumanisation, self-dehumanisation (i.e., the self-perception of being less than human), and stigmatisation (i.e., the negative taint applied to some groups) remain unexplored. The aim of this research is thus to investigate the relations between these processes. Metadehumanisation, self-dehumanisation, self-stigma (and its subdimensions) and environmental satisfaction were assessed in 120 inpatients with SAUD and analysed in a mediational model. Stigma awareness was positively associated with metadehumanisation, whereas environmental satisfaction was negatively associated with metadehumanisation. Stigma's application to the self was associated with increased self-dehumanisation. Self-stigma and self-dehumanisation are closely intertwined phenomena. Self-dehumanisation seems to follow a multi-step process suggesting that some steps, such as dehumanisation awareness, are missing from current models of dehumanisation.     

From Group Member to Democratic Citizen: How Deliberating with Fellow Jurors Reshapes Civic Attitudes

This investigation assesses the attitudinal impact of one of America’s most distinctive and famous group activities—jury deliberation. Tocqueville and the U.S. Supreme Court have both reasoned that jury service can promote civic engagement and recent research supports this view. The present study examines whether the attitudinal impact of jury deliberation depends on the quality of one’s jury experience. Two panel surveys of 2,410 total jurors tested the reciprocal relationship between the subjective experience of deliberation and the changes in civic attitudes toward oneself, fellow citizens, and public institutions. Principal results of structural equation models showed multiple effects of jury deliberation on attitudes, but there were no effects on one’s civic identity and political self‐efficacy. Reciprocally, every civic attitude except faith in fellow citizens was predictive of deliberative experience in at least one of the two studies. Overall, the study bolsters the claim of deliberative democratic theorists that the experience of consequential face‐to‐face talk can make private individuals into public citizens by reinforcing their confidence in fellow citizens and public institutions.
