The Necklace of Numbers

The necklace of numbers is a symbol that came in one of my dreams at the end of 2006, at the time when I was about to leave France, my native country, and come to the United States. As I was going through the process of becoming an American citizen, I felt compelled to reconnect to my French roots. The result was this personal account which tells the most important dreams that led me to this country. It is also a tale of a mid-life transformation, a tale of an immigrant viewed from inside, and a tale of individuation by following the path of love.     

Modality-Dependent and -Independent Factors in the Organisation of the Signed Language Lexicon: Insights From Semantic and Phonological Fluency Tasks in BSL

We used fluency tasks to investigate lexical organisation in Deaf adults who use British sign language (BSL). The number of responses produced to semantic categories did not differ from reports in spoken languages. However, there was considerable variability in the number of responses across phonological categories, and some signers had difficulty retrieving items. Responses were richly clustered according to semantic and/or phonological properties. With respect to phonology, there was significantly more clustering around the parameters “handshape” and “location” compared to “movement”. We conclude that the BSL lexicon is organised in similar ways to the lexicons of spoken languages, but that lexical retrieval is characterised by strong links between semantics and phonology; movement is less readily retrieved than handshape and location; and phonological fluency is difficult for signers because they have little metaphonological awareness in BSL and because signs do not display the onset salience that characterises spoken words.     

The Development of Adolescent Generalized Anxiety and Depressive Symptoms in the Context of Adolescent Mood Variability and Parent-Adolescent Negative Interactions

This study explored the influence of adolescent mood variability on the symptom development of generalized anxiety and depression in the context of parent-adolescent negative interactions. Participants were 456 adolescents (55.7 % male) from a community sample, who were followed from age 13 to 16 years. During 4 annual assessments, adolescents reported on their generalized anxiety and depressive symptoms, and both parents and adolescents on levels of negative interactions with each other. Within each study year, adolescents rated their daily mood states during 5 consecutive days for 3 times per year (total of 9 weeks). The absolute differences between mood states on consecutive days were summed to construct a mood variability score. Results showed that high levels of adolescent mood variability predicted increases in generalized anxiety and depressive symptoms across the studied period. No influence of negative interactions on anxiety and depression development was found, but positive predictive links from mood variability to negative interactions at age 14 and 15 appeared. The study underscores the role of adolescent mood variability in the development of symptoms of generalized anxiety and depression during adolescence, but found little evidence for an influence of parent-adolescent negative interactions on internalizing problem development.     

Imaging Brain Effects of APOE4 in Cognitively Normal Individuals Across the Lifespan

The ε4 allele of the apolipoprotein E (APOE4) is associated with an increased risk of developing Alzheimer’s disease (AD). Hence, several studies have compared the brain characteristics of APOE4 carriers versus non-carriers in presymptomatic stages to determine early AD biomarkers. The present review provides an overview on APOE4-related brain changes in cognitively normal individuals, focusing on the main neuroimaging biomarkers for AD, i.e. cortical beta-amyloid (Aβ) deposition, hypometabolism and atrophy. The most consistent findings are observed with Aβ deposition as most studies report significantly higher cortical Aβ load in APOE4 carriers compared with non-carriers. Fluorodeoxyglucose-positron emission tomography studies are rare and tend to show hypometabolism in brain regions typically impaired in AD. Structural magnetic resonance imaging findings are the most numerous and also the most discrepant, showing atrophy in AD-sensitive regions in some studies but contradicting results as well. Altogether, this suggests a graded effect of APOE4, with a predominant effect on Aβ over brain structure and metabolism. Multimodal studies confirm this view and also suggest that APOE4 effects on brain structure and function are mediated by both Aβ-dependent and Aβ-independent pathological processes. Neuroimaging studies on asymptomatic APOE4 carriers offer relevant information to the understanding of early pathological mechanisms of the disease, although caution is needed as to whether APOE4 effects reflect AD pathological processes, and are representative of these effects in non-carriers.     

Automated testing of cognitive performance in monkeys: Use of a battery of computerized test systems by a troop of semi-free-ranging baboons (<Emphasis Type="Italic">Papio papio</Emphasis>)

Fagot and Paleressompoulle (2009) published an automated learning device for monkeys (ALDM) to test the cognitive functions of nonhuman primates within their social groups, but the efficiency of the ALDM procedure with large groups remains unknown. In the present study, 10 ALDM systems were provided ad lib to a troop of 26 semi-free-ranging baboons that were initially naive with computerized testing. The test program taught baboons to solve two-alternative forced choice (2AFC) and matching-to-sample (MTS) tasks. A million trials were recorded for the group during a period of 85 days (Experiment 1). Their analysis shows that 75% of the baboons participated at high frequencies and quickly learned the 2AFC and MTS tasks. In Experiment 2, we compared the baboons’ behavior when the ADLM systems were either accessible or closed. ALDM reduced frequencies of object-directed behaviors, but had no overt consequence on social conflicts. In Experiment 3, we tested the process of the global or local attributes of visual stimuli in MTS-trained baboons in order to illustrate the efficiency of ALDM for behavioral studies requiring complex experimental designs. Altogether, the results of the present study validate the use of ALDM to efficiently test monkeys in large social groups. ALDM has a strong potential for a variety of scientific disciplines, including for biomedical research.

When change-oriented feedback enhances motivation,well-being and performance: A look at autonomy-supportive feedback in sport

ObjectivesChange-oriented feedback (aka negative feedback) serves two important functions: it motivates athletes and guides them towards performance improvement. However, it can also lead to negative consequences such as anxiety or a decrease in athletes' self-esteem and in the quality of the coach–athlete relationship. We propose that change-oriented feedback quality is key in predicting athletes' reaction to this type of feedback. Based on SDT, we further suggest that a high quality change-oriented feedback must be autonomy-supportive. To test this hypothesis, we first define and measure an autonomy-supportive change-oriented feedback. We then investigate the relative impact of change-oriented feedback's quantity and quality on athletes' phenomenological experiences and performance.MethodIn total, 340 athletes and 58 coaches participated in this study. Coaches and athletes filled out a questionnaire after a training session. HLM analyses were used to take into consideration the hierarchical structure of the data.ResultsHLM analyses first show that an autonomy-supportive change-oriented feedback is empathic, accompanied by choices of solutions, based on clear and attainable objectives known to athletes, avoids person-related statements, is paired with tips, and given in a considerate tone of voice. Results also show that feedback quality predicts athletes' outcomes above and beyond feedback quantity and coaches' other autonomy-supportive behaviours.ConclusionResults are discussed in light of their contribution to self-determination theory, the feedback literature and the improvement of coaches' training.     

Guilt and regret: The determining role of interpersonal and intrapersonal harm

The purpose of the present research was to examine which types of harm play a determining role in experiences of guilt and regret. In two studies it is shown that guilt results from interpersonal harm and regret from harm to oneself. Moreover, the second study showed that guilt generally increases as a function of the level of negative interpersonal consequences of one's behaviour. It was also demonstrated that regret increased as a function of the level of negative intrapersonal consequences but not as a function of the level of negative interpersonal consequences. Results are discussed in terms of theoretical dimensions underlying experiences of guilt and regret.     

Distinct and shared cognitive functions mediate event- and time-based prospective memory impairment in normal ageing

Prospective memory (PM) is the ability to remember to perform an action at a specific point in the future. Regarded as multidimensional, PM involves several cognitive functions that are known to be impaired in normal ageing. In the present study we set out to investigate the cognitive correlates of PM impairment in normal ageing. Manipulating cognitive load, we assessed event- and time-based PM, as well as several cognitive functions, including executive functions, working memory, and retrospective episodic memory, in healthy participants covering the entire adulthood. We found that normal ageing was characterised by PM decline in all conditions and that event-based PM was more sensitive to the effects of ageing than time-based PM. Whatever the conditions, PM was linked to inhibition and processing speed. However, while event-based PM was mainly mediated by binding and retrospective memory processes, time-based PM was mainly related to inhibition. The only distinction between high- and low-load PM cognitive correlates lies in an additional, but marginal, correlation between updating and the high-load PM condition. The association of distinct cognitive functions, as well as shared mechanisms with event- and time-based PM, confirm that each type of PM relies on a different set of processes.     

Varieties of trust‐betrayal: emotion and relief patterns in different domains

This study investigates the emotional responses to betrayal in two domains—social norms and personal acquaintances. The study relies on a newly developed Betrayal‐Domain Questionnaire and the Portrait Value Questionnaire. Study 1 confirmed the existence of two distinct betrayal domains differing in the pattern of emotional response evoked, in the actions that relieve negative emotions and the influence of values on the emotional response. In the social norms domain, betrayal evokes predominantly anger‐related emotions that can be alleviated effectively, whereas in the personal domain, more profound negative emotions are elicited by betrayal and fewer actions can relieve them. Study 2 replicates the findings with a modified questionnaire designed to comply with more stringent methodological restrictions.
