Materialism moderates the impact of mortality salience on impulsive tendencies toward luxury brands.

Luxury goods have been shown to help individuals coping with death-related anxiety. However, the extent to which the symbolic value allocated to possessions (i.e., materialism) moderates this effect is still unclear. Here, we investigated the impact of materialism on impulsive approach tendencies toward luxury clothing brands in a context of mortality salience. Results showed that the impact of mortality salience was moderated by materialism with lower impulsive approach tendencies toward luxury clothing brands observed in non-materialistic participants. These findings highlight how materialism values may impact luxury consumption through impulsive pathways in a situation of death-related anxiety.

Homophobia: An Impulsive Attraction to the Same Sex? Evidence From Eye-Tracking Data in a Picture-Viewing Task.

INTRODUCTION: Some models suggest that homophobia can be explained as a denied attraction toward same-sex individuals. While it has been found that homophobic men have same-sex attraction, these results are not consistent. AIM: This study drew on the dual-process models to test the assumption that sexual interest in homosexual cues among men high in homophobia will depend on their specific impulses toward homosexual-related stimuli. METHODS: Heterosexual men (N = 38) first completed a scale measuring their level of homonegativity. Then, they performed a manikin task to evaluate their impulsive approach tendencies toward homosexual stimuli (IAHS). MAIN OUTCOMES MEASURES: A picture-viewing task was performed with simultaneous eye-tracking recording to assess participants' viewing time of the visual area of interest (i.e., face and body). RESULTS: IAHS positively predicted the viewing time of homosexual photographs among men with a high score of homonegativity. Men with a high homonegativity score looked significantly longer at homosexual than at heterosexual photographs but only when they had a high IAHS. CONCLUSION: These findings confirm the importance of considering the variability in impulsive processes to understand why some (but not all) men high in homophobia have homosexual interest. These findings reinforce the theoretical basis for elaborating a dual-process model for behaviors in the sexual context.

Homophobia Is Related to a Low Interest in Sexuality in General: An Analysis of Pupillometric Evoked Responses.

INTRODUCTION: A recent study by Cheval et al (J Sex Med 2016;13:825-834) found that individuals high in homophobia look significantly less long at sex-related photographs, regardless of their nature (ie, homosexual or heterosexual). Because viewing time is under some conscious control, this result could indicate that individuals high in homophobia have a low sexual interest in any sexual stimuli or are consciously motivated to avoid sexual material in line with their conscious values. AIM: To determine the mechanism underlying shorter viewing time of sex-related photographs in individuals high in homophobia using pupil dilatation, which is considered a spontaneous, unconscious, and uncontrollable index of sexual interest. METHODS: Heterosexual men (N = 36) completed a questionnaire assessing their level of homo-negativity and then performed a picture-viewing task with simultaneous eye-tracking recording to assess their pupillary responses to the presentation of sexually related or neutral photographs. MAIN OUTCOME MEASURES: Non-linear mixed models were carried out to fit the individual non-linear trajectories of pupillary reaction. Different parameters were obtained including the final asymptote of the pupillary response. RESULTS: Results showed that the final pupil size of men high in homophobia increased significantly less to the presentation of sex-related images (ie, heterosexual and homosexual) than the pupil size of men low in homophobia. In contrast, no significant difference in the final pupil size reaction toward homosexual images (vs heterosexual images) emerged between men high and men low in homophobia. CONCLUSION: Theoretically, these findings reinforce the necessity to consider that homophobia might reflect concerns about sexuality in general and not homosexuality in particular.

Developmental trajectories of physical activity during elementary school physical education.

OBJECTIVE: Physical education (PE) during school provides an opportunity for children to be physically active. Few empirical studies have investigated developmental trajectories and determinants of objective moderate to vigorous physical activity (MVPA) during PE classes. The purpose of this study was to examine the developmental trajectories and determinants of MVPA during PE lessons in young children (8-12years of age) in primary schools. METHODS: Students in grades 5-7 (n=1202; 51.2% girls) were recruited from 17 elementary schools from the Geneva canton in 2012-2013. The percentage of time spent in accelerometer-assessed MVPA during regular PE lessons was used as a dependent variable. RESULTS: Linear mixed-model analyses revealed (a) that boys had a higher percentage of MVPA than girls, but none of the children reached the recommended activity levels (i.e., 50% of the PE class time spent in MVPA), (b) a linear decrease in the percentage of MVPA with age, (c) that higher perceived competence predicted a higher percentage of MVPA, and (d) that higher perceived competence reduced the negative linear effect of age among boys, but not among girls. CONCLUSION: The percentage of PE time spent in MVPA did not reach recommendations made by Centers for Disease Control and Prevention and decreased from 8 to 12years old both for boys and girls. Perceived competence appears crucial to reduce MVPA decline for boys, but not for girls.

Development of burnout perceptions during adolescence among high-level athletes: a developmental and gendered perspective.

This study examined (a) the developmental trajectories of athlete burnout perceptions, (b) the gender differences on these trajectories, and (c) the interactions in the developmental trajectories of the three burnout dimensions. A five-wave longitudinal study was conducted with 895 athletes (47.6% female; Mage = .67). Results of multilevel growth models revealed that during adolescence, "reduced sense of accomplishment" linearly decreased and was higher for girls than boys. Moreover, "emotional/physical exhaustion" increased then decreased, and seemed to have been attenuated at time points in which athletes also had higher levels of "sport devaluation." Finally, "sport devaluation" increased over time with higher increases for girls than boys. Results of our study depicted the general and the gendered shape of the trajectory of burnout perceptions during adolescence, and underlined the advantages of considering the multifaceted nature of burnout to enable a deeper examination of the within-person synergies in the development of the three dimensions.

In search of better practice in executive functions assessment: Methodological issues and potential solutions.

The multicomponent nature of executive functions (EF) has long been recognized, pushing for a better understanding of both the commonalities and the diversity between EF components. Despite the advances made, the operationalization of performance in EF tasks remains rather heterogeneous, and the structure of EF as modeled by confirmatory factor analyses (CFA) is still a topic of debate (Karr et al., 2018). The present work demonstrates these two issues are related, showing how different operationalizations in task-based performance indicators impact the resulting models of EF structure with CFA. Using bootstrapped data from 294 children (8-12 years old) and nine EF tasks (tapping inhibition, working memory, and cognitive flexibility), we first show improved model convergence and acceptance when operationalizing EF through single tasks' scores (e.g., incongruent trials, Flanker task) relative to difference scores (e.g., incongruent minus congruent trials, Flanker task). Furthermore, we show that response times exhibit poor model convergence and acceptance compared not only to accuracy but also drift rate. The latter, a well-known indicator in drift-diffusion models, is found to present the best trade-off between convergence and acceptance to model EF with CFA. Finally, we examine how various operationalizations of performance in EF tasks impact CFA model comparison in the assessment of EF structure and discuss the theoretical foundations for these results.

Aerobic fitness and academic achievement: Disentangling the indirect role of executive functions and intelligence.

Research in children points to aerobic fitness as a source of individual differences in academic achievement. By examining the indirect effects of executive functions (EF) and intelligence on the relationship between aerobic fitness and academic achievement, the present study provides novel insight about the cognitive mechanisms underlying this relationship. 218 children (8-10 years) completed the following assessments: (i) a VO2max test to assess aerobic fitness; (ii) four tasks tapping components of EF (i.e., inhibition and cognitive flexibility); (iii) sub-tests of the Kaufman Brief Intelligence Test to assess fluid and crystallized intelligence; and (iv) sub-tests of arithmetic, spelling, and reading achievement (WRAT 3rd edition). Structural equation modeling (SEM) was conducted to examine the indirect role of EF and intelligence on the relationship between aerobic fitness and sub-domains of academic achievement. Covariate analyses included age, pubertal timing, and socio-economic status. Preliminary analysis via linear regression showed a direct effect of aerobic fitness on arithmetic achievement, whereas no effect was observed on spelling and reading achievement. Importantly, multiple mediation SEM revealed the direct effect of aerobic fitness on arithmetic achievement disappeared after accounting for the indirect effects of EF, whereas intelligence did not contribute significantly on this complex mediation process. Moreover, among EF components, cognitive flexibility, was the main driver of the relationship between aerobic fitness and arithmetic achievement. Unpacking which components of EF and intelligence affect the link between aerobic fitness and academic achievement, holds the promise of better understanding the heterogeneity still present in the literature.

Hippocampal volume predicts fluid intelligence in musically trained people.

Recently, age-related hippocampal (HP) volume loss could be associated with a decrease in general fluid intelligence (gF). In the present study we investigated whether and how extensive musical training modulates human HP volume and gF performance. Previously, some studies demonstrated positive effects of musical training on higher cognitive functions such as learning and memory, associated with neural adaptations beyond the auditory domain. In order to detect possible associations between musical training and gF, we bilaterally segmented the HP formation and assessed the individual gF performance of people with different levels of musical expertise. Multiple regression analyses revealed that HP volume predicts gF in musicians but not in nonmusicians; in particular, bilaterally enhanced HP volume is associated with increased gF exclusively in musically trained people (amateurs and experts). This result suggests that musical training facilitates the recruitment of cognitive resources, which are essential for gF and linked to HP functioning. Musical training, even at a moderate level of intensity, can thus be considered as a potential strategy to decelerate age-related effects of cognitive decline.

An extended validation of the Communal Coping Strategies Inventory for Competitive Team Sports: A multilevel approach.

A questionnaire that can properly measure communal coping in sport is required to further investigate and understand how individuals in a team collectively cope with stressful sport situations. The Communal Coping Strategies Inventory for Competitive Team Sports (CCSICTS; Leprince et al., 2019) needed to be validated at the collective level and in its situational form to be used in broader sport situations. The aims of the present work were to improve and further validate the factorial structure of the CCSICTS at both individual and team levels. With a sample of 380 French athletes, representing 56 teams, Study 1 showed support for a multilevel, hierarchical and four-dimensional factorial structure of the revised version of the CCSICTS at both individual and team levels. With a sample of 641 French athletes, representing 75 teams, Study 2 confirmed the factorial structure obtained in Study 1 at individual and team levels, and its validity in sport-specific situations. The results of both studies also highlighted a bifactorial structure, allowing interpretation of communal coping as an overall team capacity to adapt to stress. As such, the psychometric qualities of the CCSICTS-R have been established at individual and team levels. The CCSICTS-R enables proper and distinct measurement of the characteristics of communal coping in sport (i.e., hierarchical, multidimensional, multilevel, both situational and dispositional) and can be used from both research and practical perspectives.

The antecedents and consequences of autonomous and controlled motivation: Domain specificity and motivational sequence at the situational level.

The aim of this study was to investigate the level of specificity of the different regulation types described by Self-Determination Theory, and to evaluate its impact on the links with its antecedents and consequences, in an academic context. In line with the school-subject-specificity hypothesis, we postulated that autonomous motivation types (AM types) would be more specific to the situational level than controlled motivation types (CM types). Moreover, we hypothesized that AM types would be, at this level, more strongly associated with its antecedents and consequences than CM types. Three hundred fourteen university students were asked to complete online questionnaires assessing their motivation, motivational antecedents (i.e., autonomy-supportive climate and self-concept) and consequences (i.e., emotions and grades) in various courses. As expected, results from structural equation modeling confirmed that AM types were more specific to the situational level than CM types. Moreover, a higher number of significant correlations were found between motivation and its antecedents and consequences in the corresponding course for AM than for CM types. Educational implications and directions for future research are discussed.

The Effects of Cognitive-Affective Switching With Unpredictable Cues in Adults and Adolescents and Their Relation to "Cool" Executive Functioning and Emotion Regulation.

The impact of emotion on executive functioning is gaining interest. It has led to the differentiation of "cool" Executive Functioning (EF) processes, such as cognitive flexibility, and "hot" EF processes, such as affective flexibility. But how does affective flexibility, the ability to switch between cognitive and affective information, vary as a function of age and sex? How does this construct relate to "cool" executive functioning and cognitive-emotion regulation processes? In this study, 266 participants, including 91 adolescents (M = 16.08, SD = 1.42 years old) and 175 adults (M = 25.69, SD = 2.17 years old), completed a cognitive-affective switching task with specific (as opposed to general) unpredictable switches, as well as measures of inhibition, attention, and cognitive-emotion coping strategies. We expected cognitive to affective switching to be more costly than affective to cognitive switching in females versus males, as well as higher switch costs in adolescents. Using linear mixed modelling, we analysed the effect of age, sex, and types of switching on reaction time. Results show that adolescents are slower switchers than adults, and demonstrate that females, although faster switchers than males, are slower when switching from cognitive to affective content than when they are switching from affective to cognitive content. Multiple regression analyses revealed age-specific associations between cognitive-affective switching and inhibition. These results converge with reported developmental and gender specificities in EF and emotion processing, respectively. Additionally, affective flexibility could relate to differences in vigilance and inhibition.

Psychological predictors of problematic involvement in massively multiplayer online role-playing games: illustration in a sample of male cybercafé players.

BACKGROUND: Massively Multiplayer Online Role-Playing Games (MMORPGs) are video games in which a large number of players interact with one another in a persistent virtual world. MMORPGs can become problematic and result in negative outcomes in daily living (e.g. loss of control on gaming behaviors, compromised social and individual quality of life). The aim of the present study is to investigate psychological predictors of problematic involvement in MMORPGs. SAMPLING AND METHODS: Fifty-four males who played MMORPGs regularly were recruited in cybercafés and screened using the UPPS Impulsive Behavior Scale (which assesses 4 facets of impulsivity) and the Motivation to Play Online Questionnaire (which assesses personal motives to play online). Negative consequences due to excessive time spent on the Internet were assessed with the Internet Addiction Test. RESULTS: Multiple regression analysis showed that problematic use of MMORPGs is significantly predicted by: (1) high urgency (b = 0.45), and (2) a motivation to play for immersion (b = 0.35). CONCLUSION: This study showed that, for certain individuals (who are characterized by a proneness to act rashly in emotional contexts and motivated to play to be immersed in a virtual world), involvement in MMORPGs can become problematic and engender tangible negative consequences in daily life.

The Indirect Role of Executive Functions on the Relationship between Cardiorespiratory Fitness and School Grades.

PURPOSE: The aim of this study was to investigate the indirect effects of cardiorespiratory fitness on scholastic performance through executive functions. More precisely, we examined the contribution of the different domains of executive functions, and whether this relationship was specific to certain school topics. METHODS: Children 8-12 yr old completed nine cognitive tests and the multistage fitness test. Structural equation modeling techniques were used to analyze the role of different domains of executive functions (inhibition, working memory, cognitive flexibility, and a common factor to all tasks) in the relationship between cardiorespiratory fitness and school grades in three domains: (i) mathematics; (ii) grammar, spelling, and vocabulary; and (iii) text comprehension and expression. Covariate analyses included age and socioeconomic status. RESULTS: The results of this study showed that an indirect effect of the various domains of executive functions explained, in part, the relationship between cardiorespiratory fitness and (i) mathematics (ß = 0.12, SE = 0.03, P < 0.001), and between cardiorespiratory fitness and (ii) grammar, spelling, and vocabulary (ß = 0.12, SE = 0.03, P < 0.001). No relationship between cardiorespiratory fitness and (iii) text comprehension and expression was observed. Although executive functions correlated with school grades, cognitive flexibility drove the indirect effect when all executive function domains were simultaneously taken into account. CONCLUSIONS: These results show the role that executive functions play in understanding the relationship between cardiorespiratory fitness and scholastic performance. Importantly, not all executive function domains contributed equally because cognitive flexibility played a leading role in this wide age range. Furthermore, the relationship between cardiorespiratory fitness and scholastic performance was strongest for mathematics and for low-level language topics but nonsignificant for higher-level language topics, providing a more modulated view of the effect of cardiorespiratory fitness on language.

Further characterisation of self-defining memories in young adults: a study of a Swiss sample.

Several individual differences affecting four dimensions of self-defining memories (SDMs)--structure, content, affect, and autobiographical reasoning (Blagov & Singer, 2004; McLean & Fournier, 2008; Singer & Salovey, 1993)--have been observed in young adults (principally in North America). In this study we aimed to investigate the relationships between the different dimensions of SDMs, providing further evidence of the content validity of the Self-Defining Memory task. It was possible to discern two specific profiles from the three SDMs collected from each participant. Almost half the participants retrieved specific SDMs with little autobiographical reasoning and tension; the other participants retrieved an opposite profile, suggesting that there are individual differences in the cognitive and affective processes related to the construction of SDMs. The second aim of the study was to conduct across-cultural extension of research on SDMs, using a sample of Swiss young adults. The results were similar to those obtained by previous studies, suggesting a certain cultural invariability. The only difference observed concerned the number of SDMs containing meaning making. Swiss young adults attribute more explicit meanings to their memories than North American young adults, suggesting that they are more engaged in autobiographical reasoning.

Intrinsic, identified, and controlled types of motivation for school subjects in young elementary school children.

BACKGROUND: There are two approaches to the differential examination of school motivation. The first is to examine motivation towards specific school subjects (between school subject differentiation). The second is to examine school motivation as a multidimensional concept that varies in terms of not only intensity but also quality (within school subject differentiation). These two differential approaches have led to important discoveries and provided a better understanding of student motivational dynamics. However, little research has combined these two approaches. AIMS: This study examines young elementary students' motivations across school subjects (writing, reading, and maths) from the stance of self-determination theory. First, we tested whether children self-report different levels of intrinsic, identified, and controlled motivation towards specific school subjects. Second, we verified whether children self-report differentiated types of motivation across school subjects. SAMPLE: Participants were 425 French-Canadian children (225 girls, 200 boys) from three elementary schools. Children were in Grades 1 (N=121), 2 (N=126), and 3 (N=178). RESULTS: Results show that, for a given school subject, young elementary students self-report different levels of intrinsic, identified, and controlled motivation. Results also indicate that children self-report different levels of motivation types across school subjects. Our findings also show that most differentiation effects increase across grades. Some gender effects were also observed. CONCLUSION: These results highlight the importance of distinguishing among types of school motivation towards specific school subjects in the early elementary years.

The school-subject-specificity hypothesis: Implication in the relationship with grades.

The aim of the present study was to examine the implication of the differences in autonomous and controlled motivation specificity in their relationships with student's grades. The school-subject-specificity hypothesis postulates that the more autonomous the regulation is, the more specific to a school subject it is. 579 junior high school children were asked to complete a questionnaire assessing their motivation at the academic level as well as at the situational level (i.e., French, mathematics, English, and physical education), both simultaneously. As expected, results from structural equation modeling revealed that autonomous motivation was more specific to the situational level than controlled motivation. Moreover, results showed that the more specific the regulations are, the more relationships with students' grades can be found. Therefore, this study offers a new understanding of previous results between autonomous and controlled regulations with grades and of the relationships between academic self-concepts, academic achievement and motivation.

Students physical activity assessed by accelerometers and motivation for physical education during class: Should we consider lessons as a whole or only active periods?

BACKGROUND: This study explores the links between measures of motivation based on Self-Determination Theory, and physical activity (PA) indicators assessed with accelerometers during physical education lessons. METHODS: Questionnaires about motivation and psychological needs on the context of physical education were completed by 319 middle high school students, up to 5 times within a 2-year period; they were equipped with an accelerometer and videotaped during a physical education lesson. PA-related indicators were computed considering the entire duration of the lessons (strategy 1), but also retaining only active times during the lesson (strategy 2). RESULTS: When the first strategy was used very few correlations emerged between motivation constructs and PA-related indicators. On the other hand, the second strategy was more effective to detect the link between motivation and students activity during class-time, in particular with sedentary time, moderate and vigorous PA. CONCLUSIONS: This study shed light on the importance of considering how the sequences of PA sessions should be coded, in order to link psychological phenomena with PA levels, as well as to provide a meaningful support for motivational hypotheses.

More Than Meets the Eye: The Impact of Materialism on Information Selection During Luxury Choices.

Visual attention is an important condition for consumer decision-making. However, not much is known on individuals' determinants of this visual attention. Using eye tracking, this study investigated how psychological values (i.e., materialism) modulate visual attention to specific sources of information (i.e., product, brand and additional information) in the context of luxury consumption. Participants were asked to perform a forced-choice experiment, where products were randomly assigned with luxury and non-luxury brands (Experiment 1) and product information (Experiment 2). Experiment 1 revealed that materialism was related to relatively higher attention to luxury as opposed to non-luxury and higher choice proportion of products displayed with a luxury brand. Experiment 2 showed that when providing additional product information (e.g., regarding the material) in addition to the brand, all participants chose luxury products more often. Interestingly, choices seemed to be driven by enhanced attention to brand for participants with high levels of materialism when choosing luxury products. In contrast, choices were driven by text for participants with low levels of materialism for non-luxury products. This suggests that individuals with high levels of materialism may prefer luxury products for different reasons than individuals with low levels of materialism: while the first focus on the symbolic dimension conveyed by the brand (Experiment 1), the latter pay attention to the actual product characteristics (Experiment 2). Taken together, our results suggest that materialism as a psychological value has an impact on visual attention and information selection during decision-making in the context of luxury consumption.

Avoiding sedentary behaviors requires more cortical resources than avoiding physical activity: An EEG study.

Why do individuals fail to exercise regularly despite knowledge of the risks associated with physical inactivity? Automatic processes regulating exercise behaviors may partly explain this paradox. Yet, these processes have only been investigated with behavioral outcomes (i.e., based on reaction times). Here, using electroencephalography, we investigated the cortical activity underlying automatic approach and avoidance tendencies toward stimuli depicting physical activity and sedentary behaviors in 29 young adults who were physically active or physically inactive but with the intention of becoming physically active. Behavioral results showed faster reactions when approaching physical activity compared to sedentary behaviors and when avoiding sedentary behaviors compared to physical activity. These faster reactions were more pronounced in physically active individuals and were associated with changes during sensory integration (earlier onset latency and larger positive deflection of the stimulus-locked lateralized readiness potentials) but not during motor preparation (no effect on the response-locked lateralized readiness potentials). Faster reactions when avoiding sedentary behaviors compared to physical activity were also associated with higher conflict monitoring (larger early and late N1 event-related potentials) and higher inhibition (larger N2 event-related potentials), irrespective of the usual level of physical activity. These results suggest that additional cortical resources were required to counteract an attraction to sedentary behaviors. Data and Materials [https://doi.org/10.5281/zenodo.1169140].

Associating a product with a luxury brand label modulates neural reward processing and favors choices in materialistic individuals.

The present study investigated the extent to which luxury vs. non-luxury brand labels (i.e., extrinsic cues) randomly assigned to items and preferences for these items impact choice, and how this impact may be moderated by materialistic tendencies (i.e., individual characteristics). The main objective was to investigate the neural correlates of abovementioned effects using functional magnetic resonance imaging. Behavioural results showed that the more materialistic people are, the more they choose and like items labelled with luxury brands. Neuroimaging results revealed the implication of a neural network including the dorsolateral and ventromedial prefrontal cortex and the orbitofrontal cortex that was modulated by the brand label and also by the participants' preference. Most importantly, items with randomly assigned luxurious brand labels were preferentially chosen by participants and triggered enhanced signal in the caudate nucleus. This effect increased linearly with materialistic tendencies. Our results highlight the impact of brand-item association, although random in our study, and materialism on preference, relying on subparts of the brain valuation system for the integration of extrinsic cues, preferences and individual characteristics.
