Situations évaluatives menaçantes et gestion de l'attention (hypothèse de filtrage et rôle du style de traitement)

Les recherches en psychologie sociale ont mis en évidence que le caractère évaluatif d'une situation de performance influence la réussite des individus. La peur de confirmer une infériorité à un standard d'évaluation génère un inconfort psychologique et amène les individus à s'autoréguler. Cette thèse vise à comprendre à partir de quand, comment et pourquoi la situation d'évaluation détermine le fonctionnement attentionnel des individus. Nous défendons l'idée que les situations évaluatives représentent une menace pour l'image de soi et perturbent l'attention à partir du moment où les individus questionnent leurs capacités intellectuelles. Deux études démontrent qu'une situation de comparaison sociale ascendante entraine une focalisation de l'attention quand la dimension de comparaison porte sur l'intelligence. Nous postulons également que les modifications attentionnelles qui surviennent en situation évaluative se traduisent au niveau de la sélection des informations. Trois études mettent en évidence que le mécanisme de filtrage des informations est plus strict chez les participants en situation évaluative et s'établit indépendamment de phénomènes concurrents de capture attentionnelle. Enfin, nous proposons que les situations évaluatives amènent les individus à basculer dans un mode général de traitement de l'information davantage analytique. Nous faisons l'hypothèse que ce changement cognitif général qui apparaîtrait en situation évaluative est un précurseur à la mise en place de filtres attentionnels plus stricts. Trois études pointent le rôle médiateur de l'adoption d'un style de traitement analytique dans l'apparition de ces effetsResearch in social psychology highlighted that the evaluative nature of performance situations influences individuals' achievement. The fear of possibly being inferior to a standard of evaluation generates psychological discomfort and leads to self-regulation. This thesis aims to understand when, how and why evaluative situations influence individuals' attentional functioning. We defend the idea that evaluative situations represent a threat to self-image and disturb attention if individuals' intellectual abilities are questioned. Two studies demonstrate that a situation of upward social comparison leads to attentional focusing when intelligence is the dimension of comparison. We also postulate that evaluative situations lead to differences in attentional filtering. Three studies show that people in evaluative situations filter more information, and that this mechanism operates independently from concurrent phenomena of attentional capture. Finally, we propose that evaluative situations lead individuals to be in a more analytical general information-processing mode. We hypothesize that this general cognitive change is a forerunner of the implementation of stricter attentional filters in evaluative settings. Three studies show that the adoption of an analytical (i.e., local) processing style mediates the effects of evaluative situations on attention. Taken together, the results support the idea that individuals' cognitive functioning is deeply influenced by characteristics of the immediate performance situationPOITIERS-SCD-Bib. électronique (861949901) / SudocSudocFranceF

Les ressources numériques d’information offertes aux parents belges et canadiens francophones en réponse au problème de la cyberintimidation : une analyse critique du discours

Cadre de la recherche : Le mot « cyberintimidation » désigne toute situation où une personne ou un groupe communique un contenu à l’aide des technologies socionumériques, dans le but de nuire au bien-être d’une tierce personne. Cette recherche porte sur les ressources numériques d’information (RNI) offertes aux parents belges et canadiens francophones, en réponse à ce problème social. Objectifs : S’appuyant sur la théorie de l’analyse critique du discours, notre recherche vise à décrire les manières d’agir et les manières d’être les plus souvent proposées aux parents belges et canadiens francophones, puis à les évaluer au regard de ce que la recherche scientifique juge souhaitable dans ce domaine. Méthodologie : Une analyse du discours de 17 RNI belges et de 35 RNI canadiennes a été réalisée. Toutes les propositions traduisant des manières d’agir et les manières d’être dans ces documents ont été classées dans des catégories d’analyse tirées de la documentation scientifique. Résultats : Le discours des RNI belges prescrit des modes d’intervention en situation de cyberintimidation qui sont proactifs ; des actions préventives misant sur la promotion du respect d’autrui ; une éducation aux médias prescriptive de bons usages ; l’exercice d’une parentalité démocratique à tendance autoritaire. Le discours des RNI canadiennes prescrit des modes d’intervention en situation de cyberintimidation axés sur le bien-être de l’enfant-victime ; des actions préventives portées sur la compréhension de l’univers sociomédiatique des jeunes ; une éducation aux médias misant sur l’accompagnement et le dialogue ouvert ; l’exercice d’une parentalité démocratique à tendance permissive. Conclusions : Les deux pays se distinguent sur plusieurs plans en matière de manières d’agir et de manières d’être promues dans les discours des RNI. Nos observations rejoignent les conclusions d’enquêtes montrant que l’exercice de la parentalité en Europe latine se fait selon un modèle plus autoritaire que celui qui est en vogue au Canada. Contribution : Notre recherche confirme le postulat de la théorie de l’analyse critique du discours selon lequel les discours sont orientés par des connaissances de sens commun (croyances, normes, valeurs) géographiquement et culturellement situées.Research Framework : The term “cyberbullying” refers to any situation where a person or group communicates content using social-digital technologies in order to harm the well-being of a third person. This research focuses on digital information resources (DIR) addressed to French-speaking parents in Belgium and Canada, in response to this social problem. Objectives : Based on the theory of critical discourse analysis, our research aims to describe the “ways of acting” and the “ways of being” most often proposed to French-speaking parents in Belgium and Canada, then to evaluate them in terms of what scientific research judges appropriate in this area. Methodology : An analysis of the discourse of 17 Belgian DIRs and 35 Canadian DIRs was conducted. All the propositions presenting “ways of acting” and “ways of being” in these documents have been classified in analytical categories taken from the scientific documentation. Results : The discourse of the Belgian DIR prescribes modalities of intervention in the situation of cyberbullying which are proactive ; preventive actions focusing on the promotion of respect for others ; a media education prescribing good uses ; the exercise of a democratic parenting with an authoritarian tendency. The discourse of Canadian DIR prescribes modes of intervention in cyberbullying that focus on the well-being of the child-victim ; preventive actions aimed at understanding the socio-media universe of young people ; media education based on support and open dialogue ; the exercise of a democratic parenting with a permissive tendency. Conclusions : The two countries are different in terms of “ways of acting” and “ways of being” promoted in the discourses of the DIR. Our observations are consistent with the findings of surveys showing that parenting in Latin Europe is conducted in a more authoritarian way than in Canada. Contribution : Our research confirms the postulate of the critical discourse analysis theory to which discourses are oriented by common sense knowledge (beliefs, norms, values) geographically and culturally located

National Stereotypes and Robots' Perception: The “Made in” Effect

In the near future, the human social environment worldwide might be populated by humanoid robots. The way we perceive these new social agents could depend on basic social psychological processes such as social categorization. Recent results indicate that humans can make use of social stereotypes when faced with robots based on their characterization as “male” or “female” and a perception of their group membership. However, the question of the application of nationality-based stereotypes to robots has not yet been studied. Given that humans attribute different levels of warmth and competence (the two universal dimensions of social perception) to individuals based in part on their nationality, we hypothesized that the way robots are perceived differs depending on their country of origin. In this study, participants had to evaluate four robots differing in their anthropomorphic shape. For each participant, these robots were presented as coming from one of four different countries selected for their level of perceived warmth and competence. Each robot was evaluated on their anthropomorphic and human traits. As expected, the country of origin's warmth and competence level biased the perception of robots in terms of the attribution of social and human traits. Our findings also indicated that these effects differed according to the extent to which the robots were anthropomorphically shaped. We discuss these results in relation to the way in which social constructs are applied to robots

Multidifferential study of identified charged hadron distributions in ZZ-tagged jets in proton-proton collisions at s=\sqrt{s}=13 TeV

Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a $Z$ boson. The charged-hadron distributions are studied longitudinally and transversely to the jet direction for jets with transverse momentum 20 $< p_{\textrm{T}} < 100$ GeV and in the pseudorapidity range $2.5 < \eta < 4$. The data sample was collected with the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.64 fb$^{-1}$. Triple differential distributions as a function of the hadron longitudinal momentum fraction, hadron transverse momentum, and jet transverse momentum are also measured for the first time. This helps constrain transverse-momentum-dependent fragmentation functions. Differences in the shapes and magnitudes of the measured distributions for the different hadron species provide insights into the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-013.html (LHCb public pages

Study of the B−→Λc+Λˉc−K−B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-} decay

The decay $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ is studied in proton-proton collisions at a center-of-mass energy of $\sqrt{s}=13$ TeV using data corresponding to an integrated luminosity of 5 $\mathrm{fb}^{-1}$ collected by the LHCb experiment. In the $\Lambda_{c}^+ K^{-}$ system, the $\Xi_{c}(2930)^{0}$ state observed at the BaBar and Belle experiments is resolved into two narrower states, $\Xi_{c}(2923)^{0}$ and $\Xi_{c}(2939)^{0}$, whose masses and widths are measured to be $$m(\Xi_{c}(2923)^{0}) = 2924.5 \pm 0.4 \pm 1.1 \,\mathrm{MeV}, \\ m(\Xi_{c}(2939)^{0}) = 2938.5 \pm 0.9 \pm 2.3 \,\mathrm{MeV}, \\ \Gamma(\Xi_{c}(2923)^{0}) = \phantom{000}4.8 \pm 0.9 \pm 1.5 \,\mathrm{MeV},\\ \Gamma(\Xi_{c}(2939)^{0}) = \phantom{00}11.0 \pm 1.9 \pm 7.5 \,\mathrm{MeV},$$ where the first uncertainties are statistical and the second systematic. The results are consistent with a previous LHCb measurement using a prompt $\Lambda_{c}^{+} K^{-}$ sample. Evidence of a new $\Xi_{c}(2880)^{0}$ state is found with a local significance of $3.8\,\sigma$, whose mass and width are measured to be $2881.8 \pm 3.1 \pm 8.5\,\mathrm{MeV}$ and $12.4 \pm 5.3 \pm 5.8 \,\mathrm{MeV}$, respectively. In addition, evidence of a new decay mode $\Xi_{c}(2790)^{0} \to \Lambda_{c}^{+} K^{-}$ is found with a significance of $3.7\,\sigma$. The relative branching fraction of $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ with respect to the $B^{-} \to D^{+} D^{-} K^{-}$ decay is measured to be $2.36 \pm 0.11 \pm 0.22 \pm 0.25$, where the first uncertainty is statistical, the second systematic and the third originates from the branching fractions of charm hadron decays.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-028.html (LHCb public pages

Measurement of the ratios of branching fractions R(D∗)\mathcal{R}(D^{*}) and R(D0)\mathcal{R}(D^{0})

The ratios of branching fractions $\mathcal{R}(D^{*})\equiv\mathcal{B}(\bar{B}\to D^{*}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(\bar{B}\to D^{*}\mu^{-}\bar{\nu}_{\mu})$ and $\mathcal{R}(D^{0})\equiv\mathcal{B}(B^{-}\to D^{0}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(B^{-}\to D^{0}\mu^{-}\bar{\nu}_{\mu})$ are measured, assuming isospin symmetry, using a sample of proton-proton collision data corresponding to 3.0 fb${ }^{-1}$ of integrated luminosity recorded by the LHCb experiment during 2011 and 2012. The tau lepton is identified in the decay mode $\tau^{-}\to\mu^{-}\nu_{\tau}\bar{\nu}_{\mu}$. The measured values are $\mathcal{R}(D^{*})=0.281\pm0.018\pm0.024$ and $\mathcal{R}(D^{0})=0.441\pm0.060\pm0.066$, where the first uncertainty is statistical and the second is systematic. The correlation between these measurements is $\rho=-0.43$. Results are consistent with the current average of these quantities and are at a combined 1.9 standard deviations from the predictions based on lepton flavor universality in the Standard Model.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-039.html (LHCb public pages

Être évalué, se sentir menacé : impact sur l’attention, la motivation et la réussite

Dans nos sociétés dites « méritocratiques », l’évaluation des individus tient une place centrale. Que ce soit à l’école ou au travail, les pratiques évaluatives permettent d’apprécier l’adéquation d’un individu avec un standard et de distribuer les récompenses en fonction du résultat de l’évaluation. Au cours de la vie d’un individu, les récompenses issues d’une évaluation positive sont diverses et souvent cruciales, allant de bonnes notes à l’école, au passage dans la classe supérieure, l’ob..
