Facilitation effect of observed motor deviants in a cooperative motor task: Evidence for direct perception of social intention in action

Spatiotemporal parameters of voluntary motor action may help optimize human social interactions. Yet it is unknown whether individuals performing a cooperative task spontaneously perceive subtly informative social cues emerging through voluntary actions. In the present study, an auditory cue was provided through headphones to an actor and a partner who faced each other. Depending on the pitch of the auditory cue, either the actor or the partner were required to grasp and move a wooden dowel under time constraints from a central to a lateral position. Before this main action, the actor performed a preparatory action under no time constraint, consisting in placing the wooden dowel on the central location when receiving either a neutral (“prêt”–ready) or an informative auditory cue relative to who will be asked to perform the main action (the actor: “moi”–me, or the partner: “lui”–him). Although the task focused on the main action, analysis of motor performances revealed that actors performed the preparatory action with longer reaction times and higher trajectories when informed that the partner would be performing the main action. In this same condition, partners executed the main actions with shorter reaction times and lower velocities, despite having received no previous informative cues. These results demonstrate that the mere observation of socially driven motor actions spontaneously influences the low-level kinematics of voluntary motor actions performed by the observer during a cooperative motor task. These findings indicate that social intention can be anticipated from the mere observation of action patterns.     

Happier together. Social cohesion and subjective well‐being in Europe

Despite mushrooming research on “social” determinants of subjective well‐being (SWB), little is known as to whether social cohesion as a collective property is among the key societal conditions for human happiness. This article fills this gap in investigating the importance of living in a cohesive society for citizens' SWB. For 27 European Union countries, it combines the newly developed Bertelsmann Foundation's Cohesion Index with individual well‐being data on life evaluation and psychological functioning as surveyed in the recent European Quality of Life Survey. The main results from multi‐level analyses are as follows. First, Europeans are indeed happier and psychologically healthier in more cohesive societies. Second, all three core domains of cohesion increase individuals' SWB. Third, citizens in the more affluent part of Europe feel the positivity of social cohesion more consistently than those in the less affluent part. Finally, within countries, cohesion is good for the SWB of resource‐rich and resource‐poor groups alike. Our findings also shed new light on the ongoing debate on economic progress and quality of life: what makes citizenries of affluent societies happier is, in the first place, their capacity to create togetherness and solidarity among their members—in other words, cohesion.     

Social influence on metacognitive evaluations: The power of nonverbal cues

Metacognitive evaluations refer to the processes by which people assess their own cognitive operations with respect to their current goal. Little is known about whether this process is susceptible to social influence. Here we investigate whether nonverbal social signals spontaneously influence metacognitive evaluations. Participants performed a two-alternative forced-choice task, which was followed by a face randomly gazing towards or away from the response chosen by the participant. Participants then provided a metacognitive evaluation of their response by rating their confidence in their answer. In Experiment 1, the participants were told that the gaze direction was irrelevant to the task purpose and were advised to ignore it. The results revealed an effect of implicit social information on confidence ratings even though the gaze direction was random and therefore unreliable for task purposes. In addition, nonsocial cues (car) did not elicit this effect. In Experiment 2, the participants were led to believe that cue direction (face or car) reflected a previous participant's response to the same question—that is, the social information provided by the cue was made explicit, yet still objectively unreliable for the task. The results showed a similar social influence on confidence ratings, observed with both cues (car and face) but with an increased magnitude relative to Experiment 1. We additionally showed in Experiment 2 that social information impaired metacognitive accuracy. Together our results strongly suggest an involuntary susceptibility of metacognitive evaluations to nonverbal social information, even when it is implicit (Experiment 1) and unreliable (Experiments 1 and 2).     

Does COVID-19 impact the frequency of threatening events in dreams? An exploration of pandemic dreaming in light of contemporary dream theories

Ninety-one dreams collected during the Covid-19 pandemic (the epidemic-situation sample) were compared with ninety-one dreams collected before the start of the epidemic (the non-epidemic-situation sample). The dreams were classified according to their content, using methods based on previous studies. The frequency of themes was compared to predictions that would be anticipated by three contemporary theories of dreaming: 1) threat simulation theory (TST); 2) incorporation continuity hypothesis (ICH); and 3) social simulation theory (SST). The epidemic-situation sample dreamed more of threatening events than the non-epidemic-situation sample (supporting the TST) and more of non-aggression threatening events, possibly due to the hyperassociation during sleep. However, the epidemic-situation sample did not show a greater prevalence of illness events in dreams (not supporting the ICH). Additionally, there was no significant difference in social neutral and positive events in dreams between the two samples as would have been predicted by the SST.     

The use of antibiotics in veterinary medicine: Representations of antibiotics and biosecurity by pig farmers

The heavy reliance on antibiotics in livestock farming has contributed to the development of antimicrobial resistance. To tackle this phenomenon, it is important to know the determinants of their use. Thus, this study investigated the way in which French pig farmers perceive antibiotics and biosecurity depending on their farm's department and ALEA (Animal Level of Exposure to Antimicrobials). A qualitative study was carried out on 87 livestock farms of a French agricultural cooperative specialising in pig production. The results show a social representation of antibiotics organized around the notion of demedication (i.e. the elimination or reduction of reliance on antibiotics). Concerning biosecurity, “large consumers” of antibiotics associate it with the idea of constraints, regulatory standards and temporal distances separating them from this practice.     

An adaptive temporal-causal network model to analyse extinction of communication over time

The persistence of information communicated between humans is difficult to measure as it is affected by many features. This paper presents an approach to computationally model the cognitive processes of information sharing to describe persistence or extinction of communication in Twitter over time. The adaptive mental network model explains, for example, how an individual can experience information overflow on a topic, and how this affects the sharing of information. Parameter tuning by Simulated Annealing is used to identify characteristics of the network model that fit to empirical data from Twitter. The data collected is related to the independentism in Catalunya, Spain, which is considered a global issue with repercussion in Europe.     

Driving examiners’ views on data-driven assessment of test candidates: An interview study

Vehicles are increasingly equipped with sensors that capture the state of the driver, the vehicle, and the environment. These developments are relevant to formal driver testing, but little is known about the extent to which driving examiners would support the use of sensor data in their job. This semi-structured interview study examined the opinions of 37 driving examiners about data-driven assessment of test candidates. The results showed that the examiners were supportive of using data to explain their pass/fail verdict to the candidate. According to the examiners, data in an easily accessible form such as graphs of eye movements, headway, speed, or braking behavior, and color-coded scores, supplemented with camera images, would allow them to eliminate doubt or help them convince disagreeing test-takers. The examiners were skeptical about higher levels of decision support, noting that forming an overall picture of the candidate’s abilities requires integrating multiple context-dependent sources of information. The interviews yielded other possible applications of data collection and sharing, such as selecting optimal routes, improving standardization, and training and pre-selecting candidates before they are allowed to take the driving test. Finally, the interviews focused on an increasingly viable form of data collection: simulator-based driver testing. This yielded a divided picture, with about half of the examiners being positive and half negative about using simulators in driver testing. In conclusion, this study has provided important insights regarding the use of data as an explanation aid for examiners. Future research should consider the views of test candidates and experimentally evaluate different forms of data-driven support in the driving test.     

Assessing carpooling drivers and barriers: Evidence from Bangkok,Thailand

Carpooling, an innovative transportation sharing economy, has been created to benefit the economy, environment, and society, easing the negative influences of the current transportation system. Therefore, this study explored the key factors that may drive consumers’ intentions to use carpooling services in Bangkok, Thailand. Regarding the theoretical framework, this study applied Social Exchange Theory (SET) and Self-Determination Theory (SDT) and evaluated the data from 409 respondents using Partial Least Square Structural Equation Modelling (PLS-SEM) analysis. There are three important findings in this study. First, although the increase in trust would reduce the privacy risk, the effect is not significant. Second, perceived risk has no impact on consumers’ intentions to use carpooling. Third, sustainability, enjoyment, and economic benefit would significantly form the perceived value, and the perceived value would affect intention to use. The findings enrich the literature on combining SET and SDT and provide theoretical and managerial insights on carpooling research.     

The effects of embedding social identities on perceived leadership outcomes and the intentional mobilization of group members

According to Identity Leadership, effective leaders make the group matter by embedding social identities in material reality. Across two studies, we explored the potential importance of embedding social identities on group members' perceptions of leader trust, influence, conflict and intentional mobilization. In Study 1, 74 competitive varsity athletes read a vignette describing a coach who was either embedding or not embedding social identities. Participants presented with a coach who was embedding social identities reported significantly greater leader trust, leader influence and intentional mobilization, and significantly lower leader conflict. In Study 2, four football teams each comprising six athletes were assigned to one of two quasi-experimental conditions where a coach either: (1) spent two weeks embedding social identities before spending two weeks not embedding them; or (2) spent two weeks not embedding social identities before spending two weeks embedding them. When a leader stopped embedding social identities after embedding them for two weeks, group members' trust in their leader significantly reduced. When a leader started embedding social identities after not embedding them for two weeks, group members' perceptions of leader trust, leader influence and intentional mobilization significantly increased. Taken together, findings provide preliminary evidence that embedding social identities is beneficial for leader outcomes and intentional mobilization compared to a non-embedding leadership approach.     

The influence of social networks within sports teams on athletes’ eating and exercise psychopathology: A longitudinal study

Teammates have been found to have an impact on athletes’ eating and exercise psychopathology via multiple influence mechanisms (e.g., modelling, making critical comments). However, far less is known about the role of the team social network (i.e. the pattern and strength of relationships between teammates). This novel longitudinal study aimed to explore how athletes’ eating and exercise psychopathology becomes more (convergence) or less (divergence) similar to their teammates’ over time and to explore how this varies for male and female athletes. A second aim was to identify the role of team social network variables (e.g., popularity) in determining individuals’ levels of eating and exercise psychopathology. Athletes (N = 199, mean age 18 years, n = 123 female) from 20 teams/training groups completed a survey regarding their teammate relationships and eating/exercise psychopathology (Eating Disorder Inventory-2; Athlete Compulsive Exercise Test) at three time points over a 7-month period. Significant interaction effects between time and gender were noted for athlete team variability in eating and exercise psychopathology, where both convergence and divergence of eating and exercise psychopathology was evident. In addition, being well connected to teammates, acting as the bridge between groups of teammates or being part of a cohesive team were longitudinally associated with reduced exercise psychopathology. Disordered eating and exercise prevention strategies should look to harness the behavioural convergence effect demonstrated here, by encouraging healthy eating/exercise practices among teammates. Furthermore, coaches should foster cohesive teammate relationships and be aware of how an athlete’s social positioning within their team may affect their susceptibility to exercise psychopathology.
