Motor planning between 4 and 7 years of age: Changes linked to executive functions

In the present study, we adopted the conceptual frameworks of Miyake et al. (2000) (organization of executive functions) and Sergeant (2000) (linking executive function to motor behaviour) to assess developmental changes in executive functions and motor behaviour, using a planning task with a sample of 4–7-years old children. More precisely, the aim of the study was to characterize the development of motor response planning between the ages of 4 and 7 as a measure of the integration of multiple executive function processes, namely inhibition, shifting and working memory, and to gain insight into the concurrent developmental contributions of these processes. Participants were divided into two groups: group 1 was composed of 24 children aged 4–5 years and group 2 was composed of 20 children aged 6–7 years. Each participant took tests for shifting, inhibition, working memory and motor planning (the egg-planning task). Our results suggest that the egg-planning task requires the inhibition of a pre-potent but inappropriate response, and to a lesser extent the manipulation of working memory strategies. These results are discussed in relation to the development of each executive function component.     

The influence of alexithymia and music on the incidental memory for emotion words

Alexithymia is a multifaceted personality construct which encompasses difficulties in identifying and expressing feelings along with an externally oriented cognitive style. We investigated whether congruent vs. incongruent emotional musical priming (happy and angry music) during encoding would moderate the effects of alexithymia on recognition rates. We found that high alexithymia scorers recognized fewer joy and anger words than low scorers. Angry music decreased recognition rates in high alexithymia scorers compared to low alexithymia scorers. The congruency and incongruency effects between music and words depended on alexithymia level. The anger deficit in high alexithymia scorers and the possible support provided by happiness cues are discussed. Copyright © 2010 John Wiley & Sons, Ltd.

Development of category formation for faces differing by age in 9‐ to 12‐month‐olds: An effect of experience with infant faces

We examined category formation for faces differing in age in 9‐ and 12‐month‐olds, and the influence of exposure to infant faces on such ability. Infants were familiarized with adult or infant faces, and then tested with a novel exemplar from the familiarized category paired with a novel exemplar from a novel category (Experiment 1). Both age groups formed discrete categories of adult and infant faces, but exposure to infant faces in everyday life did not modulate performance. The same task was conducted with child versus infant faces (Experiment 2). Whereas 9‐month‐olds preferred infant faces after familiarization with child faces, but not child faces after familiarization with infant faces, 12‐month‐olds formed discrete categories of child and infant faces. Moreover, more exposure to infant faces correlated with higher novel category preference scores when infants were familiarized with infant faces in 12‐month‐olds, but not 9‐month‐olds. The 9‐month‐old asymmetry did not reflect spontaneous preference for infant over child faces (Experiment 3). These findings indicate that 9‐ and 12‐month‐olds can form age‐based categories of faces. The ability of 12‐month‐olds to form separate child and infant categories suggests that they have a more exclusive representation of face age, one that may be influenced by prior experience with infant faces.     

When memory shifts toward more typical category exemplars: accentuation effects in the recollection of ethnically ambiguous faces

In 4 studies, the authors examined the impact of categorization on the recollection of ethnically ambiguous faces. Participants were presented with faces lying at various locations on mixed-race continua (i.e., Caucasian-North African and Caucasian-Asian faces were used as source images in a morphing program). In all studies, the prevalence of exclusive ethnic features in a face distorted participants' recollections of the face toward faces more typical of the category. Specifically, the recollection of 30% North African (or 30% Asian) faces shifted toward Caucasian source faces, whereas the recollection of 70% North African (or 70% Asian) faces shifted toward North African (Asian) source faces. Memory distortions did not emerge for extremely ambiguous (50%) faces and proved larger on mixed-race than same-race continua (Studies 3 and 4). Memory distortions also emerged with high levels of confidence. The authors elaborate on the theoretical and practical implications of these findings.     

When collective memories of victimhood fade: Generational evolution of intergroup attitudes and political aspirations in Belgium

Collective memory theories propose that groups' remembrances of their past depend upon their current social situation. In Belgium, a significant proportion of Dutch speakers share a collective memory of past victimisation by French speakers and fight for an ever‐larger autonomy of their region. Yet, as the respective economic, political and social situations of the linguistic regions of Belgium recently evolved with a reversal of fortunes, the current experience of younger Dutch speakers does not fit the traditional memory anymore. We thus predicted that the collective memories of victimhood would decline amongst them, thus bringing changes in intergroup attitudes and political aspirations. Three generations were compared in a survey of 1226 French‐speaking and 1457 Dutch‐speaking individuals. For both groups, younger generations evidenced less regionalist and more integrative positions than older ones. However, these effects were stronger for Dutch‐speaking respondents, and for them, collective memory of victimhood mediated the relation linking age and identification with Belgium, intergroup attitudes and political aspirations. We concluded that the current social context has decisive consequences for collective remembrances, which, in turn, impact intergroup relations and political attitudes and choices.     

Development of the Basel Version of the Awareness of Social Inference Test – Theory of Mind (BASIT-ToM) in healthy adults

Impairments of Theory of Mind (ToM) abilities occur in a wide range of brain disorders. Therefore, reliable and ecologically valid examination of these abilities is a crucial part of any comprehensive neuropsychological assessment. An established and ecologically valid, English-language test identifying deficits in ToM abilities is “The Awareness of Social Inference Test – Social Inference Minimal (TASIT-SIM)”. However, no comparable German-language ToM test currently exists. In this study, we aimed to develop the first German-language adaption of TASIT-SIM in healthy adults. We selected 13 scenes [four scenes per message type (i.e., honesty, simple sarcasm, paradoxical sarcasm) and one practice scene] out of the 30 TASIT-SIM scenes. In collaboration with a film institute, we filmed each scene at three different intensities. These intensity version scenes were then administered to 240 healthy adults, equally distributed in sex and age, ranging from 35 to 92 years. By applying Rasch analysis, we selected intensity versions that showed neither floor nor ceiling effects in the majority of ToM questions in participants whose ToM abilities were in the medium range. In conclusion, we have developed the first German-language adaption of TASIT-SIM, i.e., the “Basel Version of the Awareness of Social Inference Test – Theory of Mind (BASIT-ToM)”. The BASIT-ToM incorporates the strengths of TASIT-SIM, while overcoming its limitations such as inconsistencies in cinematic realization and ceiling effects in healthy participants. Next, the BASIT-ToM needs to be validated in healthy people and clinical populations.     

Applying the SIDE model to brainwriting: The impact of intergroup comparison and anonymity on creative performance

According to the Social Identity model of Deindividuation Effects, intergroup comparison under anonymity accentuates social identity salience, potentially increasing motivation to work for one's group. The present experiment aimed to examine whether intergroup comparison and anonymity could boost creative performance in a brainwriting task. Sixty participants, randomly assigned to groups, wrote their ideas on sticky notes of the same (anonymity) or different color (individuation). To reinforce social identity salience, half the groups were told that their performance would be compared with other groups. As predicted, anonymity and intergroup comparison boosted both the number of nonredundant ideas produced by group members (fluency), and diversity of ideas pertaining to different categories (flexibility). By contrast, when social identity was not salient, anonymity led to an increase in the originality of ideas.
