The intergroup bias makes us to place a greater value on our group members than other group members. In society, people sort themselves into groups and sometimes they label other groups as weak and incompetent. In some situations, minority groups are viewed as threats by majority groups when they differ too much from them. The effects of such attitudes and behaviors can be profound on society and communications, and lead to discrimination against outgroups and a social division. In this study, we review literature in this area in order to find practical ways to reduce prejudice and in-group bias. We discuss related influencing factors such as intergroup contact, intergroup acceptance, intergroup similarities, social norms, status of a group, and size. This study provides some significant takeaways include the relationship between anxiety and in-group bias and our tendency to behave less prejudiced in times of confidence and less stress; as well as the effect of revealing intergroup similarities through education and social media. Other procedures are also listed that can be used by everyone especially policymakers and researchers to find and develop effective approaches to improve societies by overcoming in-group bias. Other methods are also listed that can be used by everyone especially policymakers and researchers to find and develop effective approaches to improve societies by overcoming in-group bias.

Objective: This study aimed to investigate the mediating role of anxiety in the relationship between parental conflict and adolescent sleep problems. Methods: A descriptive correlational design was employed using a sample of 404 adolescents from Pakistan, selected based on the Morgan and Krejcie table. Participants completed standardized questionnaires measuring perceived parental conflict, anxiety symptoms, and sleep disturbances. Data analysis was conducted using SPSS-27 for Pearson correlation analysis and AMOS-21 for Structural Equation Modeling (SEM). The assumptions of normality, linearity, and multicollinearity were confirmed prior to analysis. The SEM approach allowed for testing both direct and indirect pathways within the proposed mediation model. Findings: Results from Pearson correlation indicated significant positive associations between parental conflict and anxiety (r = .51, p < .001), anxiety and sleep problems (r = .55, p < .001), and parental conflict and sleep problems (r = .47, p < .001). The structural model demonstrated good fit indices (χ² = 204.38, df = 84, χ²/df = 2.43, GFI = 0.94, AGFI = 0.91, CFI = 0.96, TLI = 0.95, RMSEA = 0.059). SEM analysis showed that parental conflict significantly predicted anxiety (b = 0.38, p < .001) and sleep problems (b = 0.19, p < .001), while anxiety significantly predicted sleep problems (b = 0.42, p < .001). The indirect effect of parental conflict on sleep problems through anxiety was also significant (b = 0.16, p < .001), confirming the mediating role of anxiety. Conclusion: The findings indicate that anxiety is a significant mediator in the relationship between parental conflict and adolescent sleep disturbances. These results underscore the need for family-based and anxiety-focused interventions to address sleep problems in adolescents exposed to high-conflict home environments.

Previous research has identified correlations between individual differences, such as age, and perceptual processes. However, the specific roles of these factors in face and house detection and the categorization of ambiguous stimuli remain inadequately understood. To address this issue, we employed a face/house categorization task to investigate how participants of different ages perceive human agents versus non-natural objects amidst varying levels of visual noise (40%, 50%, 60%, and 70%). Our results revealed that older participants exhibit longer reaction times (RT) in face detection under low-noise, ambiguous conditions (40% noise)—pointing toward a selective effect of age on face processing rather than on other object categories, such as houses.

Objective: The aim of this study was to investigate the mediating role of body checking behavior and body image in the relationship between emotional regulation and coping styles with binge eating disorder. Methods: The research design was a cross-sectional descriptive study of a correlational nature. The target population consisted of all women visiting clinics in Shiraz, and a sample of 200 women was selected using the convenience sampling method. The measurement tools used in this study included the Body Checking and Body Image Questionnaire, the Emotion Regulation Questionnaire, the Coping Styles Questionnaire, and the Binge Eating Disorder Scale. The obtained data were analyzed at both descriptive and inferential levels. In the descriptive section, indices such as mean, standard deviation, minimum, and maximum scores were calculated. At the inferential level, Pearson correlation coefficient and path analysis with structural equation modeling were conducted. Findings: The results indicated that body checking behavior and body image, as mediating variables, create a significant relationship between emotional regulation and coping styles with binge eating disorder. Both emotional regulation and body checking behavior directly and indirectly predicted binge eating disorder. Additionally, coping styles, particularly problem-focused coping, helped reduce binge eating behaviors, whereas emotion-focused and avoidant coping styles had more negative effects on this disorder. Conclusion: These results emphasize that body image and checking behaviors can increase body dissatisfaction and contribute to the persistence of binge eating disorder.
