Do goal cue and motor activity impact preschoolers’ working memory?

Preschoolers are well known for their poor working memory (WM) performance. This could result from goal neglect, which would hamper the setting of maintenance strategies. Previous studies have shown that preschoolers’ WM performance can be improved in game-like tasks, because they provide cues to support goal maintenance. However, in these studies, it was unclear what features of the task (either the main toy or the motor activity required by the game) provide efficient cues. The aim of the present study was to disentangle the two features to examine cue effects in 5- to 7-year-old children. No improvement of WM performance was observed when the toy was a potential goal cue, whereas the motor activity had a detrimental effect in all age groups. The latter effect could result from a distraction of attention from attention-based maintenance activities. Hence, preschoolers' poor WM performance would not be fundamentally due to goal neglect.

La gestion des émotions et ses déficits,chez les personnes atteintes de douleur chronique : une revue systématisée des études relatives à l’alexithymie, à l’intelligence émotionnelle, à la régulation émotionnelle et au coping

The goal of this review is to synthesize the data of scientific literature on emotional management and its deficits in chronic pain. We used terms referenced in databases and MesH terms (of the United States National Library of Medicine) to perform a literature search in a powerful online search engine (EBSCOhost research databases). Four hundred and forty-nine papers, taken from international reviews and published of 1994 (because it is in the middle of the 1990s that this theme begins to be handle) to the end of January, 2015, are identified by a total 5 electronic databases with predefined keywords about emotions and chronic pain. Forty-six of which met the inclusion criteria, according to their title, their summary and their complete text. The findings suggest that some emotional management strategies and its deficits can maintain a vicious circle of negative emotional states with physiological and psychopathological consequences. Several studies show that alexithymia, emotional ambivalence and emotional suppression have a deleterious impact on pain, emotional distress (depression, anxiety) and disability. In spite of some contradictions concerning the nature of this effect (sensory or affective pain intensity or even duration of pain), it seems that alexithymia is a major variable implied in chronic pain. Inversely, experiential acceptance has a beneficial effect on psychological distress (depression, anxiety and stress). Emotional disclosure (of stressful or traumatic events) can decrease pain intensity but not disability and mental health. Likewise, emotional expression in daily life seems beneficial, but when the expression of the positive and negative feelings are distinguished, emotional expression of negative feelings increases pain, disability and distress. The whole of these findings emphasize the need to further research about emotional management in chronic non-cancer pain. It is necessary to identify and control the source of potential bias. Some hypotheses have been proposed to explain these findings. In the future, it would be interesting to use a multifactorial approach to investigate the interactions between various processes of emotional management in chronic pain patients.     

Personality determinants of the commitment to the profession of art

The model of commitment presented in the present report postulates personality to be the crucial element in the development and maintenance of commitment to the profession of art. The objectives of the research reported here were to (a) demonstrate the typicality of the artist personality and (b) identify the traits which characterize committed and uncommitted artists. Three groups of artists were compared: mature established artists described as committed over a lifetime, committed art students, and uncommitted art students. The instrument used to evaluate personality was the Adjective Check List (ACL; Gough 8c Heilbrun, 1983). Both committed and uncommitted artists presented a typical personality structure; but in contrast to the committed, the uncommitted were characterized by low self‐esteem, a negative self‐image, impaired motivation, low staying power, and an inability to find a clear direction. Both art students and mature artists agreed about the order of importance of 11 factors considered to be determinants of committment. They both placed particular emphasis on autonomy, possibility to experiment, ease of inspiration, and early identification with the profession.     

Everyday‐like memory for objects in ageing and Alzheimer's disease assessed in a visually complex environment: The role of executive functioning and episodic memory

To investigate everyday memory, more and more studies rely on virtual‐reality applications to bridge the gap between in situ approaches and laboratory settings. In this vein, the present study was designed to assess everyday‐like memory from the virtual reality‐based Human Object Memory for Everyday Scenes (HOMES) test (Sauzéon et al., 2012 , Exp. Psychol., 59, 99) in ageing and in Alzheimer's disease (AD). Two aims motivated this study: the first was to assess multiple processes of episodic memory (EM) functioning embedded within contexts closely related to real life in ageing and AD using the multi‐trial free‐recall paradigm, and the second aim was to evaluate the mediating effects of executive functioning (EF), EM, and subjective memory complaints (SMCs) on age differences in the HOMES measures and in AD. To this end, the HOMES test and neurocognitive tests of EF and EM were administered to 23 younger adults, 23 older adults, and 16 patients with AD. The results were: firstly, compared to young adults, elderly adults presented only free‐recall decline that almost disappeared in recognition condition whereas AD patients exhibited a poor clustering, learning, and recognition performance, and also a high amount of false recognition; secondly, age differences as well as AD related deficits on the HOMES test were mediated by both memory and EF measure while those observed on false memory indices were only mediated by EM measure; thirdly, the HOMES indices are related to SMCs even when episodic or EF measures are controlled. Overall, the results supported the fact that the VR‐based memory test is an appropriate device to capture age‐related differences as well as the AD effect with respect to both in situ and laboratory settings.     

Artificial intelligence for the measurement of vocal stereotypy

Both researchers and practitioners often rely on direct observation to measure and monitor behavior. When these behaviors are too complex or numerous to be measured in vivo, relying on direct observation using human observers increases the amount of resources required to conduct research and to monitor the effects of interventions in practice. To address this issue, we conducted a proof of concept examining whether artificial intelligence could measure vocal stereotypy in individuals with autism. More specifically, we used an artificial neural network with over 1,500 minutes of audio data from 8 different individuals to train and test models to measure vocal stereotypy. Our results showed that the artificial neural network performed adequately (i.e., session-by-session correlation near or above .80 with a human observer) in measuring engagement in vocal stereotypy for 6 of 8 participants. Additional research is needed to further improve the generalizability of the approach.     

Attention-Deficit Hyperactivity Disorder Symptoms and Entrepreneurial Orientation: A Replication Note

There is a small body of literature linking attention-deficit hyperactivity disorder (ADHD) and its symptoms to entrepreneurial manifestations. Some studies take a subclinical perspective by studying the presence of symptoms, while other studies take a clinical perspective by studying the formal diagnosis of ADHD. The entrepreneurial manifestations examined range from entrepreneurial intention to the choice to become self-employed and from entrepreneurial orientation (EO) to entrepreneurial success. Despite its prominence in the entrepreneurship literature, to date only one study tested for a link with EO. The present study aims to replicate the relationship between ADHD symptoms and EO using a large data set of French small business owners. We do so by discriminating between the two dimensions of ADHD, namely attention-deficit and hyperactivity, as well as the three dimensions of EO, namely innovativeness, proactiveness, and risk-taking. We do not find a link between ADHD and EO, although we do find a positive link between ADHD and the risk-taking subdimension of EO. Hyperactivity symptoms are positively related to EO, which is mainly driven by the subdimensions proactiveness and risk-taking. We do not find a link between attention-deficit symptoms and EO, though there is a negative link between attention-deficit and proactiveness.
