The role of social identity in the explanation of collective action: An intergroup perspective on the Yellow Vests movement

Social psychologists have developed influential theoretical models to understand intergroup conflicts, radicalism, and collective action. November 2018 saw the emergence of a new powerful movement in France named the Yellow Vests. Born on social media, the movement has sustained an unprecedented period of intense protests and violent clashes with the police, challenging the French government. As such, this movement offers an ideal context to examine the real-world relevance of current social-psychological theorizing. Using a social identity and self-categorization perspective, two correlational studies (three samples, N = 1,849) tested the role of self-categorization as a group member, or social identity, in accounting for individual participation in normative and nonnormative collective action. Using different operationalizations of identification, both studies confirm a powerful role of identification as a Yellow Vest and provided evidence that the effect of social media use on collective action is fully mediated by self-categorization as a Yellow Vest. An alternative model suggesting that social media use mediated the relation between social identity and collective action was not supported by the data.     

Reversible Verbal Memory Integration Deficits in Obstructive Sleep Apnoea

When presented with novel but semantically related elements after learning verbal material, healthy participants tend to endorse these items as previously learned. This reflects the normal integration and association of novel verbal information into long-term memory. How obstructive sleep apnoea (OSA) negatively impacts verbal memory performance, and whether deficits are reversible following positive airway pressure (PAP) treatment, remain elusive. We investigated immediate and delayed OSA- and PAP treatment-related effects on verbal memory integration, using a false memory paradigm. Twenty-three patients with OSA learned lists of words semantically related to target non-presented words (1) at baseline after a polysomnography diagnosis night, (2) after a consecutive polysomnography night under PAP titration, and (3) after three months of compliant PAP treatment. At each session, participants learned 10 different lists of words, each list comprising 15 semantically related items. They had then to recognize 15 minutes later (after an intermediate vigilance task) previously learned words within a list including studied words (learned), unstudied but semantically related items (lures), and non-related unstudied items (controls). Sleep quality and fatigue questionnaires, and psychomotor vigilance tests (PVT) were administered at each session. PAP treatment led to OSA remission and improvement in objective and subjective sleep quality. Crucially, recognition of learned and lure words increased after the first night under treatment and remained stable three months later, suggesting successful memory integration and restoration of semantic processes. No treatment-related outcome was found on PVT performance. OSA exerts a detrimental but PAP-reversible effect on verbal learning and semantic memory integration mechanisms underlying the acquisition of novel memory representations.     

Cross‐cultural differences in object recognition: Comparing asylum seekers from Sub‐Saharan Africa and a matched Western European control group

Nowadays, more and more people report about their memories in cross‐cultural contexts. In international criminal settings and asylum procedures, object recognition tests can provide valuable information, for example, about weapons used during a crime or landmarks from the claimed region of origin. This study was the first to compare object recognition performance by asylum seekers from Sub‐Saharan Africa to a matched Western European control group. African participants performed worse than European participants on perceptual tests involving transformations from two‐ to three‐dimensional representations, but both groups performed equally well on an object recognition test that involved transformation from three‐ to two‐dimensional representations. However, African participants were significantly more likely to respond “yes” on the recognition test (i.e., an acquiescence response style) than European participants. Our findings elucidate cultural differences in responding on an object recognition test. Judges, juries, and immigration officials would be wise to take these differences into account when evaluating recognition performance in cross‐cultural contexts.     

Psychometric Properties of the French Version of the Pictorial Scale of Perceived Movement Skill Competence for Young Children (PMSC)

ObjectiveThe objective of this study was to examine the psychometric properties of a French version of the pictorial scale of Perceived Movement Skill Competence for Young Children (PMSC), which is aligned with the third version of the Test of Gross Motor Development.MethodA sample of 219 French-speaking Canadian children (5 to 12 years old) participated in this study.ResultsResults supported the factor validity and reliability of a 13-item version of the PMSC encompassing two factors (i.e., ball skills and locomotor skills). Subsequent analyses supported the weak, partial strong, and partial strict invariance of responses to the PMSC as a function of sex. Additionally, analyses revealed that boys displayed significantly higher perceived ball skill competence than girls. Results also supported a lack of differential item functioning (DIF) and latent mean differences as a function of body mass index and physical activity/sport involvement, but revealed evidence of DIF and latent mean differences as a function of age. More precisely, these results show that older children displayed significantly: (a) higher scores on the sliding item and lower scores on the kicking item relative to younger children; and (b) lower scores on perceived locomotor skills competence than younger children.ConclusionOverall, results suggest that the French version of the PMSC has acceptable psychometric properties and can be confidently used in research or practice to assess children's perceived movement skill competence.     

The role of athletes' pain-related anxiety in pain-related attentional processes

Numerous researchers have highlighted the social determinants of athletes' attitude toward pain, yet little is known about the role of cognitive processes and emotions that are related to pain in sport endeavors. There is evidence, in a dot probe paradigm, that individuals with chronic pain selectively orient their attention toward pain-related stimuli, but no studies have differentiated between the two attentional processes of hypervigilance that are evident in athletes: facilitated detection of threat and difficulty in disengaging attention from threatening stimuli. In the present study using a dot probe paradigm, we examined whether professional rugby players (N=58) with high pain-related anxiety (HPA) would show an attentional bias for pain-related threat, and whether this hypervigilance would reflect difficulty disengaging from threat or facilitated detection of threat. Rugby players with HPA oriented their attention toward pain-related threat with a concomitant difficulty disengaging from threat. Difficulty disengaging from painful stimuli may increase anxiety, and thus be maladaptive in sport. This is the first study to identify pain-related anxiety as a vulnerability marker in athletes' attentional biases.     

Fragile visual short-term memory is an object-based and location-specific store

Fragile visual short-term memory (FM) is a recently discovered form of visual short-term memory. Evidence suggests that it provides rich and high-capacity storage, like iconic memory, yet it exists, without interference, almost as long as visual working memory. In the present study, we sought to unveil the functional underpinnings of this memory storage. We found that FM is only completely erased when the new visual scene appears at the same location and consists of the same objects as the to-be-recalled information. This result has two important implications: First, it shows that FM is an object- and location-specific store, and second, it suggests that FM might be used in everyday life when the presentation of visual information is appropriately designed.     

La gestion de la souffrance par le psychologue clinicien. Étude des impacts et des stratégies de coping

We focus in this study on strategies used by clinical psychologists to cope with their own or patient psychological distress in the framework of help relationship. A self-administered form was sent to listings of professionals by e-mail. The sample is made of 187 French clinical psychologists. To cope with patients’ suffering, psychologists use mostly avoidance coping style. And the strategies they prefer are “supervision”, “personal therapy” and “speaking with colleagues” (problem focused coping strategies). To cope with their own distress, which has a lot of negative impacts on help relationship, psychologists have most frequently a problem focused coping style but their favourite strategy is to “lighten their schedules”. And almost a quarter of the sample presents a significant level of distress. In conclusion, results show that psychological distress management by psychologists is an important question with a lot of ethical questions.     

Evidence Supporting the Importance of Peripheral Visual Information for the Directional Control of Aiming Movement

The focus of the present study was on determining whether the high level of directional accuracy found in aiming studies in which the subjects can see their hand in the visual periphery supports the existence of a kinetic visual channel or, rather, the advantage of binocular over monocular vision for movement directional control. The limits of this kinetic visual channel were also explored. The results of the 1st experiment indicated that seeing one's hand in the visual periphery is sufficient to ensure optimal directional aiming accuracy. Further, no differences in aiming accuracy were noted between monocular and binocular vision. These results supported the existence of a visual kinetic channel. In the 2nd experiment, whether this kinetic visual channel would operate with movements slower (55°/s) than those usually used in studies that had proved its existence (over 110°/s) was determined. The results indicated that this visual kinetic channel was operative even at relatively slow movement velocities. Central vision of the hand seemed to be used for on-line directional control of relatively slow movements.
