Abstract Background: The purpose of the study was to explore the relationships between exposure to weapon toys and aggressive behavior. Methods: The study sample included 104 six-year-old kindergarten children. Half of them were randomly assigned to play with weapon toys (experimental group) or non-weapon toys (control group). A Semantic Classification Task (SCT) and a Competitive Reaction Time Task (CRTT) were employed to measure aggressive cognition and aggressive behavior. A randomized controlled study was performed and a 2 x 2 (Toys, Gender) Analysis of Covariance (ANCOVA) statistical test was used to evaluate the effect of toys on aggressive cognition (reaction times to weapon pictures) and behavior (noise intensity setting), controlling for age. Mediation analysis was also conducted to test the mediating role of aggressive cognition in this effect.Results: Results indicated that playing with weapon toys increased aggressive cognition and aggressive behavior. Specifically, boys were more likely than girls to exhibit aggressive behavior in the weapon toys condition, though girls did exhibit aggressive cognition. Mediation analysis indicated that the weapon toy effect on aggressive behavior was partially mediated by aggressive cognition. Conclusions: The main findings of the study suggest that boys may be considered as the target group for aggression intervention and reduction in the context of weapon toys. Practitioners can take away the weapon toys to reduce aggressive cognition, so as to decrease children’s aggressive behavior.

Prosocial cartoon is characterized by helping others solve difficulties, including helping, donating, sharing, comforting, and cooperating. The current study examined whether viewing a prosocial cartoon decreases aggression immediately upon exposure and the potential mediating role of aggressive motivation. Participants involve 168 children (Mage = 5.87 years, SD = 0.41) nominated by teachers as aggressive from three Chinese kindergartens. Children in the treatment group watched a prosocial cartoon (American cartoon “Handy Manny”), while children in the control group watched a nonprosocial cartoon (Chinese cartoon “Fruity Robo”). Afterward, the Hot Sauce Task (HST) was employed to assess aggressive behavior, and Aggressive Motivation Questionnaire (AMQ) was employed to assess aggressive motivation. Results revealed that viewing a prosocial cartoon (vs. a nonprosocial cartoon) did reduce children’s aggression immediately upon exposure. Specifically, males showed less aggressive behavior than females upon prosocial cartoon exposure, while males showed more aggressive behavior than females upon nonprosocial cartoon exposure. Mediational analysis suggested that the prosocial cartoon effect on aggression was partially mediated by aggressive motivation, especially for males. Consistent with general aggression model (GAM), findings of the study indicated that short-term exposure to a prosocial cartoon decreased children’s aggression by reducing aggressive motivation.

Abstract Background We sought to examine the association between childhood experience of parental death (CEPD) and adulthood suicidal ideation, and the mediating role of adulthood SES in the association. Methods We analyzed a nationally representative dataset of 8609 adults from the Korea Welfare Panel Study, which is a longitudinal cohort dataset in South Korea. CEPD was measured using a question: “During your childhood (0-17 years old), have you experienced the death of parents?” We classified responses of CEPD during 2006–2011 into ‘yes,’ and the others into ‘no.’ Suicidal ideation over the past year was assessed annually during 2012–2019. As a potential mediator, adulthood educational attainment and household income in 2011 were included in the analysis. Logistic regression was applied to examine the association of CEPD with adulthood suicidal ideation across age groups (early adulthood, 19–39 years old; middle adulthood, 40–59 years old; late adulthood, ≥60 years old), after excluding people who reported lifetime suicidal ideation in 2011. Causal mediation analysis using a parametric regression model was applied to examine the mediating role of adulthood SES in the association between CEPD and adulthood suicidal ideation. Results After adjusting for potential confounders including childhood SES, CEPD was significantly associated with adulthood suicidal ideation among the late adulthood group (OR: 1.43; 95% CI: 1.13–1.81), while the association was not statistically significant among the early; and middle adulthood groups. In mediation analysis of adulthood household income, both indirect association (ORNIE: 1.05; 95% CI: 1.02–1.09) and direct association (ORNDE: 1.37; 95% CI: 1.09–1.73) were statistically significant among the late adulthood group. In the mediation analysis of adulthood education attainment among the late adulthood, only a direct association was statistically significant (ORNDE: 1.43; 95% CI: 1.14–1.80). Conclusions These results suggest that CEPD could be a risk factor for adulthood suicidal ideation. Furthermore, the findings imply that income security policy might be necessary to reduce suicide among the late adulthood group.

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.

A curriculum emphasizing instruction in areas of greatest deficit was provided to children demonstrating a developmental lag. Of 135 children so classified, 90 were placed in an experimental program and 45 participated as a control group in a regular kindergarten program. A second control group consisted of 45 randomly selected developmentally normal subjects also in a regular kindergarten program. Mean score differences between groups and sexes for general development, visual perception, language, and general readiness were obtained. Analysis of covariance showed no significant differences by treatment or sex on any of the criterion measures.

The Relationship

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.

Abstract Objectives The purpose of this exploratory non-randomized controlled study was to determine the acceptance and effectiveness of an 8-week mindfulness-based intervention (MBI) co-designed by a police officer. Methods A pretest-posttest control group design was followed. Participants (MBI group = 20; control group = 18) answered baseline and post-training self-reported measures. In addition, the weekly emotional state of the MBI group was collected. Paired-samples t-test and analysis of covariance were performed for pre-post within-group and between-group differences, respectively, as well as linear mixed effects analysis of repeated measures for week-by-week data. Results High acceptance and attendance rates, as well as significant pre-post within-group differences in the MBI group in mindfulness (η2 = 0.43), self-compassion (η2 = 0.43), depression (η2 = 0.54), anxiety (η2 = 0.46), stress (η2 = 0.51), difficulties in emotion regulation, sleep quality (η2 = 0.57), and burnout (η2 = 0.31–0.47), were identified. Moreover, police officers who underwent the MBI experienced a week by week decrease of anger, disgust, anxiety, sadness, and desire. Finally, after adjusting for pre-test scores, significant between-group differences were found in the way of attending to internal and external experiences (observing mindfulness facet; ηp2 = 0.21), depression symptoms (ηp2 = 0.23), general distress (ηp2 = 0.24), and the degree of physical and psychological exhaustion (personal burnout; ηp2 = 0.20). Conclusions The preliminary effectiveness of this MBI on psychopathology and quality of life outcomes in Spanish police officers was discussed. Previous evidence regarding the promising use of MBIs in this population was supported.

The Relationship

PurposeThe purpose of this paper is to explicate the relationship between workplace ostracism and deviant behavior, and further test the mediating role of emotional exhaustion and the moderating role of resilience.Design/methodology/approachA sample of 409 first-line production workers from four manufacturing enterprises in China was collected. A moderated mediation analysis was employed to test the hypotheses and examine the relationships proposed in the research framework.FindingsThe findings indicate that emotional exhaustion could mediate the relationship between workplace ostracism and deviant behavior. Moreover, the results from the moderated mediation analysis suggest that the mediation of emotional exhaustion is moderated by resilience such that with a higher level of resilience, the mediation effect of emotional exhaustion becomes weaker.Research limitations/implicationsThe participants of this study are limited to manufacturing enterprises, and thus our findings may not be equally valid for other types of industries. Meanwhile, this study is a cross-sectional research that could not explain the causal relationship between workplace ostracism and deviant behavior.Practical implicationsThe present research can offer some managerial implications about how to avoid the occurrence of workplace ostracism and deviant behavior for organizations.Originality/valueThis study constructs a moderated mediation model by introducing the potential mediating role of emotional exhaustion and the moderating effect of resilience in order to reveal the mechanism through which workplace ostracism relates to deviant behavior. Our research not only integrates and enriches the ideas of the Stress-Non-Equilibrium-Compensation Approach and the Transactional Model of Stress and Coping Theory but could also inform future management practices for mitigating the negative consequences of workplace ostracism.

Aim: To evaluate the effectiveness of an information leaflet in improving patient understanding of the procedure and complications of septoplasty.Design: The baseline knowledge of a group of patients who had attended a pre-assessment clinic prior to septoplasty was assessed. The procedure and its complications were then verbally explained. The patients' knowledge was then re-assessed on the morning of surgery and any improvements noted. In the second arm of the study, an information leaflet was introduced at the time of verbal instruction and any differences in improvement in knowledge were assessed.Results: Data from the two groups were analysed using an analysis of covariance with differences in baseline (pre-instruction) knowledge controlled. Additional improvements in mean recall score following leaflet distribution were highly statistically significant when compared with mean recall in the control group (p<0.001).Conclusion: The use of information leaflets increases patients' knowledge about a surgical procedure and its potential complications.

Many specialists in the field of foreign language teaching consider spelling as an important and perhaps necessary part in language teaching, and observe that spelling is a significant concern among both the language arts community and the public. The teaching of spelling is an issue that provokes strong feelings and attitudes in teachers, students, and parents as well, and those involved have strong opinions about the importance of correct spelling at school. A close look at the role of spelling in the general language curriculum, makes it known that learning to write and read in the whole language can benefit greatly from teaching spelling. Searching the Net under the keywords ‘spelling’ and ‘teaching spelling’ reveals many studies on spelling and the interest of the readers. In this study, we made use of two techniques to teach spelling, which included “the Personalized Instruction Technique”, or simply the PI technique, and “the Detection Technique” or the D technique. Meanwhile, a control group was included to make up for and take into account any possible background differences.82 kindergarten children, studying at three kindergartens in Tarom, Zanjan, took part in the study. They were randomly assigned to three groups: one control group and two experimental groups. The PI group consisted of 28 kindergarten students both boys and girls, and the Group comprised 27kindergarten students, both boys and girls. The control group, too, contained 27 kindergarten students, both boys and girls. The findings indicated that both the experimental groups that used the spelling techniques performed significantly better than the control group. Meanwhile, the PI group exceeded the DT group.
