Emotional plasticity: conditions and effects of improving emotional competence in adulthood

This study aimed to investigate (a) whether it is possible to increase emotional competence (EC) in adulthood; (b) whether this improvement results in better mental, physical, and social adjustment; (c) whether this improvement can be maintained 1 year later; and (d) whether these benefits are accompanied by a reduction in stress-hormone secretion (i.e., cortisol). One hundred and thirty-two participants were randomly assigned to an EC-enhancing intervention (in group format) or to a control group. Participants in the intervention group underwent a specifically designed 15-hr intervention targeting the 5 core emotional competencies, complemented with a 4-week e-mail follow-up. Results reveal that the level of emotional competencies increased significantly in the intervention group in contrast with the control group. This increase resulted in lower cortisol secretion, enhanced subjective and physical well-being, as well as improved quality of social and marital relationships in the intervention group. No significant change occurred in the control group. Peer reports on EC and quality of relationships confirmed these results. These data suggest that emotional competencies can be improved, with effective benefits on personal and interpersonal functioning lasting for at least 1 year. The theoretical implications of these results as well as their practical implications for the construction and the development of effective emotional competencies interventions are discussed.     

Example‐based learning: Effects of model expertise in relation to student expertise

Background. Worked examples are very effective for novice learners. They typically present a written‐out ideal (didactical) solution for learners to study. Aims. This study used worked examples of patient history taking in physiotherapy that presented a non‐didactical solution (i.e., based on actual performance). The effects of model expertise (i.e., worked example based on advanced, third‐year student model or expert physiotherapist model) in relation to students' expertise (i.e., first‐ or second‐year) were investigated. Sample. One hundred and thirty‐four physiotherapy students (61 first‐year and 73 second‐year). Methods. Design was 2×2 factorial with factors ‘Student Expertise’ (first‐year vs. second‐year) and ‘Model Expertise’ (expert vs. advanced student). Within expertise levels, students were randomly assigned to the Expert Example or the Advanced Student Example condition. All students studied two examples (content depending on their assigned condition) and then completed a retention and test task. They rated their invested mental effort after each example and test task. Results. Second‐year students invested less mental effort in studying the examples, and in performing the retention and transfer tasks than first‐year students. They also performed better on the retention test, but not on the transfer test. In contrast to our hypothesis, there was no interaction between student expertise and model expertise: all students who had studied the Expert examples performed better on the transfer test than students who had studied Advanced Student Examples. Conclusions. This study suggests that when worked examples are based on actual performance, rather than an ideal procedure, expert models are to be preferred over advanced student models.     

Serving God's Mission Together in Christ's Way: Reflections on the Way to Edinburgh 2010

This paper argues that missio Dei theology must continue to provide the basis for an ecumenical missiology, provided certain problems are revisited, in line with themes of the 2010 Edinburgh study process. Among them is the need for emphasizing the vertical dimension of a transformative spirituality, somehow neglected in earlier ecumenical theologies. Only this will prevent an over‐estimation of humanity's capacities. Within a missio Dei theology the specific role of the church is to be reaffirmed: there is no way back behind integration, which remains a cornerstone of an ecumenical approach, provided it keeps a critical distance to dogmatic ecclesiologies that tend to hinder progress towards visible unity. The debate on gospel and culture has to be urgently taken up again, through a positive appreciation of syncretism and the related search for criteria in intercultural hermeneutics. This will lead to articulating pneumatological approaches to mission with Christologies. Indeed, the New Testament texts with the most universal horizon refer to Christ as Word or Wisdom and not to the Holy Spirit. The paper moves on to ask whether then the relevance of the biblical wisdom tradition should not feature more in missiology. It could provide fertile approaches to witness in a religiously plural and ecologically damaged world. Ecumenical mission should in future be shaped by wisdom as much as it has been by prophecy, and keep both traditions in creative tension.     

La performance des élèves des communautés noires aux examens ministériels du secondaire Québécois: Cohortes 1994, 1995, 1996

This article discusses the results of various sub-groups of Quebec students from the Black community (originating from the West Indies or Africa and having French, English or Creole as their maternal language) who started high-school in the French or English sector in 1994, 1995 or 1996, on various departmental exams: history, physical sciences, written French and written English, language of instruction or second language, depending on the sector. The authors begin by presenting the socio-demographic, educational, and socio-economic profile of the population under study. The performance of the various sub-groups within each sector is then discussed and certain elements are put forward to explain the differences encountered. Finally, the authors add some concluding remarks about the potential contribution of the research, especially as it regards the identification of factors influencing schooling outcomes of visible minorities, both in Quebec and in other Canadian provinces.     

The line copy task for kinesthesia and internal movement representation: application in children

In the present study a new test is proposed and tested, which requires ability to use information both from kinesthesia and from mental rotation of previously produced cyclic movements over a distinct trajectory. This Line Copy Test (LICT) was performed by 58 children aged 7-11 years. For the S-part, the participants first had to make movements till they reached a barrier and then they were required to reproduce the same (S) movements without the barrier. For the O-part of the test the participants had to rely on an internal representation of a felt trajectory length, and reproduce the movement orthogonal (O) to the ones felt. Trajectory Length Error (TLE) and variable error (VE) were measured. Furthermore, results of the LICT were correlated to the Kinesthetic Acuity Test and a pegboard task. The general finding was that the TLE, capturing the spatial calibration of the movement, and the VE, used as a measure of noise or inconsistency in the 10 reproductions, was largest for the youngest children, but this developmental effect was not significant in the O-part of the test. Although participants of all age groups made much larger TLE in the rotated task (O-part) than in the LICT_S-part, the VE was much smaller. This can be explained by assuming that different underlying control mechanisms underlie each task. Also differences in correlations of the two parts of the test with the other measures infer that they measure dissimilar underlying entities. It is likely that at least some portion of the increased movement variability in the S-part seen during development in young children can be attributed to partly unstable kinesthetic representations for hand movements. The finding that no significant development was found on the O-part indicates that changes in the use of internal models must occur outside the age window studied.     

Even statisticians are not immune to misinterpretations of Null Hypothesis Significance Tests

We investigated the way experienced users interpret Null Hypothesis Significance Testing (NHST) outcomes. An empirical study was designed to compare the reactions of two populations of NHST users, psychological researchers and professional applied statisticians, when faced with contradictory situations. The subjects were presented with the results of an experiment designed to test the efficacy of a drug by comparing two groups (treatment/placebo). Four situations were constructed by combining the outcome of the t test (significant vs. nonsignificant) and the observed difference between the two means D (large vs. small). Two of these situations appeared as conflicting (t significant/D small and t nonsignificant/D large). Three fundamental aspects of statistical inference were investigated by means of open questions: drawing inductive conclusions about the magnitude of the true difference from the data in hand, making predictions for future data, and making decisions about stopping the experiment. The subjects were 25 statisticians from pharmaceutical companies in France, subjects well versed in statistics, and 20 psychological researchers from various laboratories in France, all with experience in processing and analyzing experimental data. On the whole, statisticians and psychologists reacted in a similar way and were very impressed by significant results. It must be outlined that professional applied statisticians were not immune to misinterpretations, especially in the case of nonsignificance. However, the interpretations that accustomed users attach to the outcome of NHST can vary from one individual to another, and it is hard to conceive that there could be a consensus in the face of seemingly conflicting situations. In fact, beyond the superficial report of “erroneous” interpretations, it can be seen in the misuses of NHST intuitive judgmental “adjustments” that try to overcome its inherent shortcomings. These findings encourage the many recent attempts to improve the habitual ways of analyzing and reporting experimental data.     

Contrast of hand preferences between communicative gestures and non-communicative actions in baboons: Implications for the origins of hemispheric specialization for language

Gestural communication is a modality considered in the literature as a candidate for determining the ancestral prerequisites of the emergence of human language. As reported in captive chimpanzees and human children, a study in captive baboons revealed that a communicative gesture elicits stronger degree of right-hand bias than non-communicative actions. It remains unclear if it is the communicative nature of this manual behavior which induces such patterns of handedness. In the present study, we have measured hand use for two uninvestigated behaviors in a group of captive olive baboons: (1) a non-communicative self-touching behavior (“muzzle wipe” serving as a control behavior), (2) another communicative gesture (a ritualized “food beg”) different from the one previously studied in the literature (a species-specific threat gesture, namely “hand slap”) in the same population of baboons. The hand preferences for the “food beg” gestures revealed a trend toward right-handedness and significantly correlated with the hand preferences previously reported in the hand slap gesture within the same baboons. By contrast, the hand preferences for the self-touching behaviors did not reveal any trend of manual bias at a group-level nor correlation with the hand preferences of any communicative gestures. These findings provide additional support to the hypothesized existence in baboons of a specific communicative system involved in the production of communicative gestures that may tend to a left-hemispheric dominance and that may differ from the system involved in purely motor functions. The hypothetical implications of these collective results are discussed within the theoretical framework about the origins of hemispheric specialization for human language.
