Implicit attitudes and the improvement of exercise capacity during pulmonary rehabilitation

The aim of this study was to examine the role of explicit and implicit attitudes in the improvement of exercise capacity during a 5-week pulmonary rehabilitation (PR). A total of 105 patients performed walking tests at baseline and at the end of PR. Change between performances was computed at the end of PR, and Minimal-Clinically-Important-Difference (MCID) were used to categorize patients as responders (i.e. change above MCID, N = 54) or non-responders (i.e. change below MCID, N = 51). At baseline, implicit attitudes were measured through a physical activity versus sedentary behavior Implicit Association Test; explicit attitudes toward physical activity and sedentary behavior were measured by questionnaires. Only implicit attitudes significantly differed between the two groups (p = .015), responders displaying implicit attitudes significantly more in favor of physical activity (M = .91, SD = .54) than non-responders (M = .60, SD = .71) at baseline. Measuring implicit attitudes in PR could help to accurately estimate patients’ motivation, and design more individualized rehabilitation programs.     

Social Influence Dynamics in Aptitude Tasks

Learning and, more generally, the development of cognitive processes in children has been thought to depend on the nature of the conflict induced by confrontation with others (i.e., socio-cognitive conflict). The aim of this article is to extend this notion to social-influence situations involving adolescents and young adults through the presentation of a model that explains social influence in aptitude tasks. This model takes into account the differences or similarities of the competencies of the source and target. It conceptualizes the social versus epistemic regulations of conflict in terms of an identity threat that can be induced by social comparison. To illustrate parts of the model, several experiments are briefly summarized. One demonstrates the conflict regulation dynamics involved in the similarities or differences of the sources' and targets' competencies, while the others show how social-influence dynamics are modified by the presence or absence of a threat to self-competence. This revised version was published online in August 2006 with corrections to the Cover Date.     

Evidence of different developmental trajectories for length estimation according to egocentric and allocentric viewpoints in children and adults

This study investigated the influence of egocentric and allocentric viewpoints on a comparison task of length estimation in children and adults. A total of 100 participants ranging in age from 5 years to adulthood were presented with virtual scenes representing a park landscape with two paths, one straight and one serpentine. Scenes were presented either from an egocentric or allocentric viewpoint. Results showed that when the two paths had the same length, participants always overestimated the length of the straight line for allocentric trials, whereas a development from a systematic overestimation in children to an underestimation of the straight line length in adults was found for egocentric trials. We discuss these findings in terms of the influences of both bias-inhibition processes and school acquisitions.     

Opening closed minds: the combined effects of intergroup contact and need for closure on prejudice

Five studies tested whether need for closure (NFC) moderates the relation between intergroup contact and prejudice toward immigrants. The results consistently showed that intergroup contact was more strongly associated with reduced levels of prejudice among people high in NFC compared to people low in NFC. Studies 1 (N = 138 students) and 2 (N = 294 adults) demonstrated this moderator effect on subtle, modern, and blatant racism. Study 2 also replicated the moderator effect for extended contact. An experimental field study (Study 3; N = 60 students) provided evidence of the causal direction of the moderator effect. Finally, Studies 4 (N = 125 students) and 5 (N = 135 adults) identified intergroup anxiety as the mediator through which the moderator effect influences modern and blatant racism as well as hostile tendencies toward immigrants. The role of motivated cognition in the relation between intergroup contact and prejudice is discussed.     

Two-to-three-year-old children's interactions with peers in child-care centres: Effects of spatial distance to caregivers

In child-care centres, the influence of caregivers on the development of peer interactions seems ambivalent and mixed results are reported in the literature. Adopting an environmental approach, we examined the effects of the caregivers’ spatial proximity on children's social behaviour. The study was carried out with 175 children (18-40 months) in 12 child-care-centre groups. Children's behaviours were observed during free plays, and both children and caregivers’ locations were recorded. When peers were nearby, children's social behaviours were compared when they were in the immediate proximity (within 2 m) and out of the immediate proximity of a caregiver. Results show that in the latter situation children spend substantially more time addressing social overture to peers and interacting with them; positive interactions with peers show a particularly marked difference. This pattern of results is exhibited by the greater part of the children. Whatever the child-care-centre group, the age subgroup or the gender considered similar results are found. Results also demonstrate that when children are in the immediate proximity of caregivers they are socially oriented towards the attractive adult partners rather than towards peers.     

Tolerance of Justice Violations: The Effects of Need on Emotional Reactions After Violating Equality in Social Dilemmas1

Equality is an important coordination rule in social dilemmas. Studies have shown that a violation of equality elicits strong negative emotions. This research addresses whether these emotional reactions occur when another group member is in need of social support. Results showed that participants reacted less negatively if equality was violated and the other person was in need. Moreover, it was shown that there are individual differences in the extent to which people are influenced by fairness violations in their emotional reactions. In particular, Conscientiousness was important for people's emotional reactions, and people low rather than high in Conscientiousness reacted more negatively. These findings are discussed in light of coordination rules and emotions in social dilemmas and individual differences.     

A thematic dialogue: towards a conclusion and a follow-up

Following the themed debate that took place after the panel, we reconsidered and explored further our hypotheses in light of the comments made by our colleagues. Clearly, it is the structural approach that underlies both the Freudian primal phantasies and the Jungian archetypes, while taking account at the same time that their approaches are informed by contemporary emergentist theories. Our discussion centred on the divergences in the cases of psychosis and neurosis, on the roles, in turn, of a return to childhood and the play of archaic representations, on the transference and countertransference functions and finally on the need to pay attention to what are deemed synchronous moments in the event.     

Computational Evidence That Frequency Trajectory Theory Does Not Oppose But Emerges From Age‐of‐Acquisition Theory

According to the age‐of‐acquisition hypothesis, words acquired early in life are processed faster and more accurately than words acquired later. Connectionist models have begun to explore the influence of the age/order of acquisition of items (and also their frequency of encounter). This study attempts to reconcile two different methodological and theoretical approaches (proposed by Lambon Ralph & Ehsan, 2006 and Zevin & Seidenberg, 2002 ) to age‐limited learning effects. The current simulations extend the findings reported by Zevin and Seidenberg (2002) that have shown that frequency trajectories (FTs) have limited and specific effects on word‐reading tasks. Using the methodological framework proposed by Lambon Ralph and Ehsan (2006) , which makes it possible to compare word‐reading and picture‐naming tasks in connectionist networks, we were able to show that FT has a considerable influence on age‐limited learning effects in a picture naming task. The findings show that when the input–output mappings are arbitrary (simulating picture naming tasks), the links formed by the network become entrenched as a result of early experience and that subsequent variations in frequency of exposure of the items have only a minor impact. In contrast, when the mappings between input‐output are quasi‐systematic or systematic (simulating word‐reading tasks), the training of new items was generalized and resulted in the suppression of age‐limited learning effects. At a theoretical level, we suggest that FT, which simultaneously takes account of time and the level of exposure across time, represents a more precise and modulated measure compared with the order of introduction of the items and may lead to innovative hypotheses in the field of age‐limited learning effects.     

Voluntary simplicity and life satisfaction: Exploring the mediating role of consumption desires

The research presented in this article investigates the relationship between adopting voluntary simplicity as a lifestyle and life satisfaction. More precisely, it seeks to understand the role that consumption desires and relative wealth play in the context of this relationship. A survey was conducted among a Canadian sample of 344 simplifiers and 267 non‐simplifiers. A statistically significant positive relationship was observed between the adoption of voluntary simplicity and a measure of satisfaction with life. This research has also established that it is partially through one's control of consumption desires that simplifiers achieve a higher level of life satisfaction. However, this was shown to be the case only among consumers with limited financial resources. Copyright © 2012 John Wiley & Sons, Ltd.
