The Relationship

The purpose of this study was to examine the relationship between gross motor skills and school day steps per minute, testing various motivational constructs as potential mediators. A convenience sample of 66 sixth-grade children (mean age = 11.6 ± 0.5 years; 30 boys, 36 girls) were recruited from one public “Zoom” school. Gross motor skills were assessed using the Test for Gross Motor Development-3rd Edition. Motivational constructs were assessed using a series of validated questionnaires. Children wore a pedometer for one school week. A bootstrap mediation analysis was employed using gross motor skills scores as the predictor variable and steps per minute as the outcome variable; the motivational constructs consisted of perceived competence, enjoyment, and self-efficacy as potential mediators. The results from a bootstrap mediation analysis yielded a statistically significant average causal mediation effect (ACME) using perceived competence as the mediator (ACME = 0.022, 95% CI [0.001, 0.054], p = .018). Perceived competence mediated 30.8% of the total effect between gross motor skill scores and steps per minute, with the entire model explaining approximately 13.6% of the variance. The relationship between gross motor skills and school day physical activity may be mediated through perceived competence in sixth-grade children.

The Relationship

Little is known about how implicit theories of intelligence and perceived competence are related. This study examines whether concern over mistakes mediates this relationship. A total of 508 students (255 girls) in grade 4 or 5 completed self-reported surveys for four consecutive years. Each year, the results of the mediation analysis indicate that students who perceive their intelligence as more malleable have a stronger sense of competence (r = .25 to .32, p < .001), while the more concerned they are over mistakes, the lower their perceived competence (r = -.18 to -.26, p < .001). At each time of measurement, the concern over mistakes weakens the relationship between the conception of intelligence and perceived competence, which remains significant and moderate, but the role of concern over mistakes tends to fade over time. Keywords: intelligence theory, mistake preoccupation, perception of competence, mediation analysis, elementary and high school education La relation entre la théorie implicite de l'intelligence et la perception de compétence reste peu connue. Cette étude examine le rôle potentiellement médiateur de la préoccupation envers l'erreur dans cette relation. Les 508 élèves participants (255 filles) de 4e année ou 5e année du primaire au début de l'étude ont répondu aux questionnaires pendant quatre ans consécutifs. Les résultats des analyses de médiation faites tous les ans indiquent que plus les élèves ont une conception dynamique de l’intelligence, plus leur perception de compétence est élevée (r = .25 à .32, p < .001) alors que plus ils sont préoccupés par l’erreur, moins leur perception de compétence est élevée (r = -.18 à -.26, p < .001). À chaque temps de mesure, la préoccupation envers l'erreur diminue significativement le lien entre la conception de l'intelligence et la perception de compétence, mais ce dernier reste significatif et modéré.

The Relationship

The Anti-Extradition Bill Movement of 2019 has caught the attention of international headlines by being a large-scale leaderless movement. This leaderless feature may have spawned from the aftermath of the 2014 Umbrella Movement, soon after which, university students voted to disaffiliate with its leadership, the Hong Kong Federation of Students. We conducted a study to examine the psychological factors that contributed to such disaffiliation, including perceived integrity-based trustworthiness and perceived competence-based trustworthiness. We tested their mediation effects on the relationship between group identification with the movement protesters and the corresponding voting decision in disaffiliation with the leader. This study recruited voters in a referendum at a university in Hong Kong to decide on its fate with the Federation of Students (N = 113). Results of ordinal logistic regression suggest that lower perceived integrity-based trustworthiness and perceived competence-based trustworthiness significantly predicted voting decision to disaffiliate with the leader. Mediation analysis with bootstrapping found a significant indirect effect of voters’ group identification with UM protesters on voting decision through perceived integrity, but not perceived competence.

The Relationship

Research has shown that perceived group status positively predicts competence stereotypes but does not positively predict warmth stereotypes. The present study identified circumstances in which group status positively predicts both warmth and competence judgments. Students (N = 86) rated one of two groups (psychologists vs. engineers) presented as either being low or high in social status on warmth and competence. Results showed that status positively predicted competence stereotypes for both groups, but warmth stereotypes only for psychologists, for whom warmth traits are perceived to be functional in goal achievement. Moreover, for psychologists perceived warmth mediated the relationship between status and perceived competence. Results are discussed in terms of the contextual malleability of the relationship between perceived status, warmth, and competence.

Abstract Background The COVID-19 pandemic brings unprecedented uncertainty and stress. This study aimed to characterize general sleep status among Chinese residents during the early stage of the outbreak and to explore the network relationship among COVID-19 uncertainty, intolerance of uncertainty, perceived stress, and sleep status. Methods A cross-sectional correlational survey was conducted online. A total of 2534 Chinese residents were surveyed from 30 provinces, municipalities, autonomous regions of China and regions abroad during the period from February 7 to 14, 2020, the third week of lockdown. Final valid data from 2215 participants were analyzed. Self-report measures assessed uncertainty about COVID-19, intolerance of uncertainty, perceived stress, and general sleep status. Serial mediation analysis using the bootstrapping method and path analysis were applied to test the mediation role of intolerance of uncertainty and perceived stress in the relationship between uncertainty about COVID-19 and sleep status. Results The total score of sleep status was 4.82 (SD = 2.72). Age, place of residence, ethnicity, marital status, infection, and quarantine status were all significantly associated with general sleep status. Approximately half of participants (47.1%) reported going to bed after 12:00 am, 23.0% took 30 min or longer to fall asleep, and 30.3% slept a total of 7 h or less. Higher uncertainty about COVID-19 was significantly positively correlated with higher intolerance of uncertainty (r = 0.506, p < 0.001). The mediation analysis found a mediating role of perceived stress in the relationship between COVID-19 uncertainty and general sleep status (β = 0.015, 95%C.I. = 0.009–0.021). However, IU was not a significant mediator of the relationship between COVID-19 uncertainty and sleep (β = 0.009, 95%C.I. = − 0.002–0.020). Moreover, results from the path analysis further showed uncertainty about COVID-19 had a weak direct effect on poor sleep (β = 0.043, p < 0.05); however, there was a robust indirect effect on poor sleep through intolerance of uncertainty and perceived stress. Conclusions These findings suggest that intolerance of uncertainty and perceived stress are critical factors in the relationship between COVID-19 uncertainty and sleep outcomes. Results are discussed in the context of the COVID-19 pandemic, and practical policy implications are also provided.

The Relationship

This research aims to determine the mediating role of social deficits in self-criticism and aggression using a sample of 695 adolescents (girls = 49%, boys = 51%), aged 12 to 19 years ( M = 14.97, SD = 1.30) from an urbanized city of Pakistan. Interpersonal Difficulties Scale, Self-Criticism Scale, and Aggressive Behavior Scale were used in the present study. Results indicated a significant positive association of social deficits with self-criticism and aggression ( p < .001). Furthermore, findings also suggested a significant positive association between self-criticism and aggression. Mediation analysis revealed that self-criticism partially mediated the relationship between social deficits and aggression. Findings are discussed in terms of the expression and manifestation of self-criticism, social deficits, and aggression in adolescents in collectivistic cultures.

Objective This work aims to further test the theory that trust mediates the interdependency between automation reliability and the rate of human reliance on automation. Background Human trust in automation has been the focus of many research studies. Theoretically, trust has been proposed to impact human reliance on automation by mediating the relationship between automation reliability and the rate of human reliance. Experimentally, however, the results are contradicting as some confirm the mediating role of trust, whereas others deny it. Hence, it is important to experimentally reinvestigate this role of trust and understand how the results should be interpreted in the light of existing theory. Method Thirty-two subjects supervised a swarm of unmanned aerial vehicles (UAVs) in foraging missions in which the swarm provided recommendations on whether or not to collect potential targets, based on the information sensed by the UAVs. By manipulating the reliability of the recommendations, we observed changes in participants’ trust and their behavioral responses. Results A within-subject mediation analysis revealed a significant mediation role of trust in the relationship between swarm reliability and reliance rate. High swarm reliability increased the rate of correct acceptances, but decreased the rate of correct rejections. No significant effect of reliability was found on response time. Conclusion Trust is not a mere by-product of the interaction; it possesses a predictive power to estimate the level of reliance on automation. Application The mediation role of trust confirms the significance of trust calibration in determining the appropriate level of reliance on swarm automation.
