Reexamining the relationship between social media and happiness: The effects of various social media platforms on reconceptualized happiness

The current study reexamined the relationship between social media use and happiness by broadening the scope of social media and rethinking the conceptualization of happiness. Specifically, this study included platforms other than Facebook and tested differential effects of each platform. Because happiness is not entirely relative, it was hypothesized that social comparison would influence only relative happiness, which is only one part of overall happiness. A two-wave longitudinal survey among Korean females revealed that the use of blogs, Instagram, and LinkedIn is positively associated with social comparison at Wave 1 (W1), whereas Twitter is negatively associated. LinkedIn use was most strongly associated with social comparison. In turn, social comparison at W1 negatively predicted relative happiness at W2 (“I am happier than my friends”) but did not predict overall happiness at W2. Social media may lead us to believe that other people’s lives are better through social comparison. However, such comparison influences only part of overall happiness or life satisfaction. Without social comparison, social media have the potential to make us happier.

Emotion,Motivation, and the Persuasive Effects of Message Framing

This study explored the effects of premessage emotions (happiness, anger, and fear) and chronic levels of motivational system activation (behavioral approach system: BAS, and behavioral inhibition system: BIS) on the processing of gain‐ and loss‐framed persuasive messages. The data showed that emotion functions (approach and avoidance), not valences (positive and negative), predicted emotions' interactions with motivational systems and framed messages. While fear was associated with BIS, happiness and anger were linked to BAS. Also, while a loss frame was more persuasive among fearful individuals, a gain frame produced more persuasion for happy and angry participants. BAS mediated persuasion when angry and happy participants read a gain frame; BIS mediated persuasion among fearful individuals who attended to a loss frame.     

Fuzzy-Based Knowledge Discovery from Heterogeneous Data in Planting Systems for Elderly LOHAS

In this paper, we propose a knowledge discovery method based on the fuzzy set theory to help elders with plant cultivation. Initially, the fuzzy sets are constructed by using the feature selection and statistical interval estimation. The min-max inference and the center of gravity defuzzification method are then used to output a candidate pattern set. Finally, a pattern discovery is adopted to obtain the patterns from the candidate set for the cultivation suggestions by considering the frequency weight and user's experience. In order to demonstrate the performance of our method in planting systems, we conduct a clicks-and-mortar cultivation platform, namely Eden Garden, for the elderly lifestyles of health and sustainability (LOHAS). The experimental results show that the accuracy rate of our knowledge discovery method can reach up to 85%. Moreover, the results of the LOHAS index scale table present that the happiness of the elders is increasing while the elders are using our proposed method.

Examining the links between active Facebook use,received likes,self-esteem and happiness: A study using objective social media data

For social media users, profile updating and receiving Likes may feel like a reward, and elicit positive emotions, reinforcing use of the platform. Could this mechanism have consequences for users’ self-esteem and happiness? Previous findings on the topic are mixed, and typically limited by use of self-reports of online activity. In the present study, we used objective behavioral data to examine the hypotheses that receiving Likes on Facebook would relate to 1) users’ level of perceived self-esteem, and 2) increased happiness via the mediating role of self-esteem. We recruited 2,349 adult Facebook users (589 men, 1,760 women; 67% aged 18–25, 26% aged 26–35, 7% aged > 35 years). Participants answered an online survey and provided access to their objective Facebook data (i.e., profile updates and received Likes). We found that frequency of users updating their profile and sharing personal content (e.g., self-generated texts, images, friends and location tags) had a direct effect on the frequency and intensity of the feedback (i.e., Likes) they received from other users in their online social network. Additionally, analyses supported a positive link between the frequency and intensity of positive feedback received by users and perceived happiness that was mediated in part by an increase in self-esteem. Overall, findings demonstrate a process linking positive online social feedback and perceived well-being.     

Do SNSs really make us happy? The effects of writing and reading via SNSs on subjective well-being

The use of social networking services has become popular with the ubiquity of digital devices, influencing individuals’ everyday lives. In this regard, this study examined how both writing and reading via SNSs affected individuals’ subjective well-being both positively and negatively. A hypothesized model was proposed to explore the mediating roles of concern about others’ feedback and self-affirmation between writing via SNSs and subjective happiness. The model also incorporated the mediating roles of feelings of relative deprivation and vicarious satisfaction between reading via SNSs and subjective happiness. Surveys were administered to 516 adult SNS users in South Korea, and the data were subjected to structural equation modeling. The findings suggest that both writing and reading via SNSs may influence individuals’ subjective happiness through multiple mediators. The findings also suggest that individuals’ gender might play a role as moderators for some of the relations in the model.

Prospect Theory,Discrete Emotions,and Freedom Threats: An Extension of Psychological Reactance Theory

Consistent with earlier research supporting the use of narratives to increase message persuasiveness, this study examined the role of guilt and happiness following exposure to organ donation narratives presented in professionally produced radio ads. As hypothesized, the loss‐frame narrative was significantly associated with heightened guilt, which was related to greater freedom threat perceptions and psychological reactance. Conversely, the loss‐frame narrative was negatively associated (p = .06) with increased happiness. Contrary to what was hypothesized, reactance was not significantly negatively associated with favorable attitudes toward registering as an organ donor. Instead, freedom threat was directly negatively related to favorable attitudes. Our results are discussed with an emphasis on the theoretical and practical implications.
