Online Social Identity Mapping ( oSIM ) in Japan
The social identity approach to health in social psychology (the so‐called “social cure”) explores the capacity for group memberships that furnish people with a positive sense of social identity to enhance their health and well‐being. Online social identity mapping (oSIM) is a tool that allows individuals to represent their social identities graphically, providing insights into the quantity and quality of these group‐based connections. However, t…
Does Mental Simulation Decrease the Empathy Gap in Help‐Seeking
People hesitate to seek help when they perceive the cost of helping as high. In general, help‐seekers overestimate the cost of helping because of errors in perspective‐taking. We examined whether three processes of mental simulation (recalling an experience of providing help, of rejecting a request for help, and of sensing the empathy gap) would decrease the cost of helping perceived by help‐seekers. Participants underwent one of the simulations …
Ninety years after Lewin
Drawing on the literature on person-culture fit, we investigated how culture (assessed as national-level familism), personality (tapped by attachment styles) and their interactions predicted social network characteristics in 21 nations/areas ( N = 2977). Multilevel mixed modeling showed that familism predicted smaller network size but greater density, tie strength, and multiplexity. Attachment avoidance predicted smaller network size, and lower d…
Unequal but not separate
Addressing inequality is a critical challenge for society as a whole and requires sustained efforts to promote fairness and opportunity for all. Filling in the resource gap across social classes is essential in reducing inequality. Previous studies have revealed that ingroup favouritism hinders the rich from cooperating with the poor and expands the wealth gap. Nevertheless, how to find ways of narrowing the gap between the rich and the poor rema…
The Self-perception of Text message Dependence Scale (STDS)
Processes of Social Influence on Sampling Behavior
Studies about attitude formation have pointed out the importance of sampling behavior. When thinking about actual social interaction scenes, it may be better to consider them as attitude‐updating processes between those who have already formed attitudes based on some experience. Sixty‐five participants took part in the experiment, in which the other's positive attitude and the participant's own prior experience were manipulated. After participant…
Trajectories of Healthcare Utilization Among Children and Adolescents With Autism Spectrum Disorder and/or Attention-Deficit/Hyperactivity Disorder in Japan
Continuous healthcare needs were common and psychiatric comorbidities were associated with complex trajectory among adolescents. The promotion of early intervention and prevention of comorbidities are important
Generalized Trust and Social Selection Process
Generalized trust relieves individuals in a socially uncertain situation from dyadic constraints of existing ties and helps them change ties with other individuals to acquire better resources. However, much evidence in the emancipation role of generalized trust as a booster of new relationship formation has been limited to laboratory experiments or cross-sectional surveys. We conducted a four-wave longitudinal survey to test whether individuals h…
Odd man out for everyone
Ostracism presents a paradox: ostracizing a member from a group has been considered anti‐normative yet has been applied in many societies. This study attempts to resolve this paradox through the idea that people ostracize an individual to maximize benefits to the whole group. A paired‐comparison paradigm was developed that forced participants to choose a target of ostracism from one of two members who provided different amounts of benefits to the…
Development of the Japanese version of the three-item loneliness scale
The results indicate that the Japanese version of the TIL Scale demonstrates adequate reliability and validity for the assessment of loneliness
Cross-Cultural Validation of Fear of Happiness Scale Across 14 National Groups
A survey of the cultural notions related to happiness and the existing empirical evidence indicate that some individuals endorse the belief that happiness, particularly an immoderate degree of it, should be avoided. These beliefs mainly involve the general notion that happiness may lead to bad things happening. Using multigroup confirmatory factor analysis and multilevel modeling, this study investigates the measurement invariance, cross-level is…
Perceived entitativity of social networks
Gender differences in social network development via mobile phone text messages
We examined the development of face-to-face (FTF) social networks and mobile/cell phone text message (MPTM)-mediated social networks, and gender differences in the social network structure of 64 male and 68 female first-year undergraduate students. Social network analysis showed that MPTM social networks consisted of dyadic relationships, and its growth was slower than FTF social networks. The intimacy of friends who communicate via both FTF and …
