How Political Overconfidence Fuels Affective Polarization in Cross-cutting Discussions
The Dunning-Kruger effect describes how poor performers overestimate their abilities while top performers underestimate their abilities. This study explores whether this effect explains the ineffectiveness of cross-cutting discussions in reducing affective polarization. We propose a moderated mediation model in which the relationship between cross-cutting discussion (wave 1) and affective polarization (wave 2) is mediated by oppositional response…
Effects of News‐Bothers‐Me on News Media Use and Political Knowledge
Objectives This study introduces the concept of news‐bothers‐me perception (NBMP) and examines how its two dimensions—annoyance due to news overload and annoyance due to perceived news bias—shape news media use and political knowledge in a high‐choice digital media environment. Methods Drawing on two waves of a national online panel survey of South Korean adults (N = 1,175) conducted prior to the 2022 presidential election, we employed autoregres…
Predispositions, partisan media, and political beliefs about female presidency in South Korea and the United States
This study investigated the effects of political predispositions and partisan media use on beliefs about candidates’ gender in political campaigns. The analysis of two national surveys, one in South Korea (Study 1) and one in the United States (Study 2), found associations between individuals’ political predispositions and beliefs regarding candidates’ gender that aligned with their political ideology and party affiliation. The results also showe…
The Corrective Effect of Fact-Checking and Hostile Media Perceptions
With the proliferation of fake news and misinformation, fact-checking journalism is booming worldwide. However, whether its corrective effect is still valid and generalizable in daily news consumption settings outside the laboratory requires further investigation. In addition, some partisans argue that the content of fact-checking news has a partisan bias that makes it unfavorable to particular political figures or parties. This perceived bias i…
Exploring the Paradox of Cross-Cutting Exposure and Affective Polarization
Previous research provides mixed results on how exposure to counter-attitudinal information (i.e. cross-cutting exposure) affects political polarization. Our study examines two theoretical models (i.e. linear and curvilinear) in the relationship between cross-cutting exposure and affective polarization. Using two waves of national panel data conducted in South Korea, the findings suggest that cross-cutting exposure affects partisans’ affective po…
Do we always cast our votes with accurate information? The mediating role of misperception in the relationship between partisan media use and retrospective voting
Most current studies on political participation have focused on political behaviors per se, rather than the criteria guiding voters. The critical consideration of whether voters cast their votes with accurate information is often overlooked but is important because a healthy and robust democracy relies on political participation informed by accurate information. This study delves into the relationships between partisan media use, misperceptions, …
Fact-Checking News Use and Political Misperception
Fact-checking can play an essential role in reducing political misperceptions. However, how effective it is in doing so has yet to be understood. This study uses data from a two-wave panel survey administered during the 2022 Korean presidential election (Wave 1: N = 1175, Wave 2: N = 948) to examine the role of fact-checking news in reducing political misperceptions in the sociopolitical context of South Korea. Based on the Orientation-Stimulus-R…
A Comparative Study between Donghak’s In-nae-cheon and the Three Essential Attitudes in Daesoon Thought
Donghak’s teaching, In-nae-cheon, means “humans are divine.” It is said, “When humans were formed, God’s blessing was required for their formation.” Donghak’s Sincerity, Respectfulness, and Faithfulness is based on believing in God, respecting God, and practicing His teachings with utmost sincerity. These are key to implementing In-nae-cheon. On the other hand, the Three Essential Attitudes in Daesoon Thought, also Sincerity, Respectfulness, and …

Impact of a Service-Learning Program Using Soccer Training on the Emotional and Behavioral Problems of Children with Developmental Disabilities
Children with developmental disabilities may develop emotional and behavioral problems that arise from difficulties in social interaction, and therefore, a process of providing and testing intervention activities for emotional and behavioral issues in the early stages of development is required. This study evaluated the effects of a 12-week service-learning exercise program on children with developmental disabilities, contrasting it with a contro…
A Comparative Study on Spiritual Humanism in Daesoon Thought
This comparative study combines the methodologies of comparative research and literature review to examine Daesoon Thought. Comparative religious analysis in the social sciences, does not presuppose an a priori framework of the essence of religion because it targets various aspects of religion which are revealed within a historical field. However, it does not decompose and return to psychological or social phenomena like social sciences. In addit…
The “Us vs. Them” Mentality
This study examines how affective polarization impacts the partisan divide in perceptions of cable news networks’ political biases. Results from a 2016 U.S. presidential election survey show that affective polarization deepens this divide, even after controlling for election involvement, partisanship strength, and cable news usage. Partisanship strength is more closely associated with in-party love than out-party hate, but out-party hate has a st…
Smartphone use and knowledge gap hypothesis
Purpose The purpose of this study is to examine the knowledge gap hypothesis in the context of smartphone use for news to understand whether mobile news consumption could bridge or widen the knowledge gap between people of higher and lower socioeconomic status (SES). Design/methodology/approach The authors examine how smartphone news consumption is associated with the knowledge gap hypothesis by analyzing a survey dataset from Hong Kong. This stu…

The rich get richer and the poor get poorer? The effect of news recommendation algorithms in exacerbating inequalities in news engagement and social capital
Personalized news recommendations shape social media users’ information environment. However, whether news recommendation algorithms asymmetrically influence users’ news engagement remains largely unknown. Drawing on the three-level digital divide framework (access, use, and outcomes), we test a moderated mediation model in which social media usage motivations influence social capital via news engagement, conditional on using algorithmic news. Us…
The effects of disagreement and unfriending on political polarization
Cross-cutting discussion is the foundation of deliberative democracy. However, previous research has reported inconsistent results regarding the effects of exposure to dissimilar perspectives on political polarization. This study aims to extend the literature by exploring how cross-cutting discussion influences affective polarization through unfriending and how this indirect effect is contingent upon exposure to incivility. The study analyzes pan…
Just a Glance, or More? Pathways from Counter-Attitudinal Incidental Exposure to Attitude (De)Polarization Through Response Behaviors and Cognitive Elaboration
Using two-wave U.S. panel survey data, this study proposes a moderated serial mediation model to examine through what paths and under what conditions incidental exposure to counter-attitudinal information on social media would enhance or mitigate polarization. The findings suggest that such exposure can indirectly polarize attitude by eliciting passive scanning behaviors, but it can also indirectly attenuate attitude polarization first through ac…

Aerobic and Anaerobic Fitness according to High-Intensity Interval Training Frequency in Youth Soccer Players in the Last Stage of Rehabilitation
In the last stage of rehabilitation, high-intensity interval training (HIIT) for improving physical fitness is appropriate for return-to-play; however, some youth athletes visit the rehabilitation center less frequently due to conflict with their distance to center, and academic schedule. We tested the effects of short-term low-frequency HIIT in 54 youth male soccer players, after dividing them into a low-frequency group (LFG, n = 27 players) and…
Biomechanical Asymmetry of Strength and Dynamic Balance Kinetics in Middle-Ages with Adhesive Capsulitis of the Hip
The representative clinical features of adhesive capsulitis of the hip (ACH) are restricted range of motion (ROM) and pain. However, reports on kinetics such as strength and dynamic balance that explain physical functions are rare. This study compared subjective hip scores using Copenhagen Hip and Groin Outcome Score (HAGOS) and ROM using a manual goniometer as well as strength using isokinetic equipment, and dynamic balance through the Y-balance…
Kinetic Effects of 6 Weeks’ Pilates or Balance Training in College Soccer Players with Chronic Ankle Instability
Lateral ankle sprain (LAS) is a common sports injury that frequently occurs in active individuals. LAS is characterized by a high recurrence rate, with a large proportion of patients progressing to chronic ankle instability (CAI). Pilates exercises have provided positive results in health care and in rehabilitation. This study compared Pilates training (PT) with traditional balance training (BT) in patients with CAI. Fifty-one college football pl…
Effects of High-Intensity Aquatic or Bicycling Training in Athletes with Unilateral Patellofemoral Pain Syndrome
Patellofemoral pain syndrome (PFPS) is one of the most common overuse injuries experienced by athletes. It is characterized by pain and functional deficits that lead to decreased performance, thereby limiting sports activity. Therefore, optimal training interventions are required to improve physical fitness and function while minimizing pain due to PFPS. This study aimed to compare and analyze the effects of high-intensity aquatic training (AT) a…
Networks and Selective Avoidance
From time to time, some social media users avoid content posted by specific people in their networks. Most research on such selective avoidance has focused on individual motivations and other psychological factors rather than on social network characteristics, and there is a need for a systematic analysis of the relationships between individuals’ social media networks and selective avoidance. This study fills that gap in the literature, drawing o…
