While there are many services that help reduce smartphone usage, most services only measure smartphone usage on a single measure, time. However, smartphone usage can be measured on a variety of scales such as time, frequency, and mainstream app category. Research on the relevance of smartphone usage to usage frequency and the users' desire to reduce smartphone usage frequency suggest that usage frequency may be an important measure for smartphone usage. Therefore, this paper tried to examine the possibility of introducing the usage frequency as a method to reduce smartphone overuse. Therefore, we compared the changes of log data before and after applying the frequency limit method and the log data before and after using the time limit method. Research has shown that the frequency limit method is more effective than the time limit method for users who use short and frequent patterns and for some apps like social media제 1 장 서 론 1 제 1 절 연구의 배경 1 제 2 절 연구를 위한 개념 정의 4 제 3 절 연구 대상 및 목적 7 제 2 장 이론적 배경 8 제 1 절 미디어 과사용 8 제 2 절 미디어 사용 조절 13 제 3 절 로그 분석 17 제 3 장 연구 문제 20 제 1 절 연구 문제 20 제 4 장 연구 방법 22 제 1 절 참여자 모집 22 제 2 절 데이터 수집 24 제 3 절 데이터 정리 28 제 4 절 분석 방법 33 제 5 장 연구 결과 35 제 1 절 Descriptive data 35 제 2 절 시간과 빈도의 관계 43 제 3 절 시간과 빈도의 변화 45 제 4 절 위반 비율 50 제 5 절 제한 시간/빈도 전, 후의 사용 패턴 변화 51 제 6 절 제한 시간/빈도 넘긴 시각의 변화 53 제 6 장 결론 56 제 1 절 결과 요약 및 논의 56 제 2 절 연구 한계 및 의의 60 참고문헌 63 Abstract 78Maste

The relationship between problematic video gaming, problematic Facebook use, and self-control dimensions among female and male gamers

The development of new technology has contributed to changes in everyday functioning. However, one possible negative aspect of new technologies is their problematic, uncontrolled use. Dysfunctional self-control is a critical aspect of problematic behavior. Consequently, the present research investigated the relationship between problematic video gaming (PVG), problematic Facebook use (PFU), and self-control dimensions among female and male gamers. The study comprised 830 videogame players (350 female gamers) aged from 15 to 31 years. PFU was assessed using the Facebook Intrusion Scale, and PVG was assessed using the Problem Video Game Playing Questionnaire. Self-control dimensions were assessed using the 50-item Nowy Arkusz Samowiedzy (SelfKnowledge New Sheet; NAS-50). Findings showed that lower goal maintenance was associated with higher PFU, whereas lower initiative and persistence was associated with higher PVG among both groups. Additionally, there was a negative association between inhibition and adjournment and problematic behaviors among male gamers. In contrast, PFU was associated inhibition and adjournment among female gamers. The findings demonstrate the difference between both genders in the relationship between PVG and self-control. These findings enable a better understanding of the relationship between problematic behaviors and self-control among gamers and the differences between female and male gamers

The Effect of a Mindfulness-Based Intervention on Attention and Cognitive Control as a Function of Smartphone Notifications.

Barriers to accessing mobile technology, particularly smartphones, have decreased substantially since the iPhone’s release in 2007, resulting in increased ownership and usage across all ages, genders, and races. Despite their ubiquity in our society, relatively little empirical work has investigated the influence of smartphones on our higher order executive functioning. Prior work has linked smartphone use with impaired cognitive control during cognitively demanding tasks, especially in heavier smartphone users. The goals of the current study were twofold. First, the study aimed to examine the effects of smartphone notifications on cognitive control and attention. And second, to determine the effects of a mindfulness-based intervention on cognitive control and attention as a function of smartphone notifications. Participants were randomly assigned to an experimental group, who received a mindfulness-based induction (MBI), or a control group. Both groups completed a computerized task to assess cognitive control (Navon Letter task), while being exposed to smartphone notifications and control sounds. EEG data were recorded continuously during the task. Results indicated that people in the MBI (vs. control) group showed worse cognitive control in terms of both behavioral performance and N2 event -related potentials. Neural markers of attention (P2) were not different between the experimental and the control groups. However, P2 amplitudes were greater on trials with smartphone notifications, suggesting that smartphone notifications impact attentional processes. These findings provide an important contribution for understanding the effects of smartphones on our cognition and offer insight into the efficacy of mindfulness-based interventions

Living with and beyond breast cancer : exploring women’s use of social media to support psychosocial health

Background: Despite the extensive use of social media, its role in supporting women living with and beyond breast cancer (LwBBC), across the survivorship trajectory, remains underexplored. Existing research has tended to focus on single or dual platform use and utilised secondary data, principally from Facebook and Twitter. In contrast, this study sought to ensure women’s experiences of use took centre stage by adopting a qualitative approach to explore social media use across the survivorship trajectory. Aims: The aims of this thesis were to: a) explore how women LwBBC use social media; b) examine how women use social media as communicative resources in relation to LwBBC; and c) make sense of how women use social media to support their psychosocial health. Methods: Twenty-one women (age range 27-64) participated in semi-structured interviews. Twelve participated in a photo-elicitation study using pre-existing photographs to explore social support. Nine participated in a photo-production study in which they took photographs (n=157) to represent how they communicate their experiences of LwBBC to others. A bricolaged approach to data analysis using thematic, polytextual and voice centred methodological approaches ensured women’s voices were brought to the fore within the analysis process. Findings: Social media use is integral to many, but not all, women’s daily lives and considered by women an appropriate space to explore their own experiences. Women describe using multiple social media platforms, such as Facebook, YouTube, Wikipedia and WhatsApp concurrently. The use of multiple platforms simultaneously to satisfy psychosocial needs demonstrates use to be more fluid and dynamic than the current literature suggests. Through listening to women’s voices, and using photographs to visualise voices, three key themes came to the fore: (i) finding relevant, timely and appropriate support; (ii) navigating disrupted identities; and (iii) (re)gaining a sense of control. Analysis shows these themes to be entangled, interconnected, and dynamic with women’s use shifting across time. Women describe social media use as both empowering but also as dislocating. Conclusions: This is the first in depth qualitative study that takes an overview of women’s engagement across social media platforms to support their experiences of LwBBC. It demonstrates significant digital labour by women through use of social media to support their physical, emotional, and (anti) social experiences of LwBBC. It indicates naturally occurring networked communities as important contributors to the ongoing psychosocial support women need at different stages of LwBBC. Social media enables women to (re) gain a sense of control and can reduce need to draw on health service provision. Knowledge of women’s use can provide insight and guidance for healthcare professionals (HCPs), producers of online content, moderators of social media communities and other women LwBBC
