Research suggests that online communication is associated with increased closeness to friends and friendship quality. Children under 13 years of age are increasingly using social networking sites (SNSs), but research with this younger age group is scarce. This study examined the relationship between SNS use and feelings of belonging among children aged 9–13 years. A self‐report questionnaire was administered to 443 children (48.98% boys), asking about their SNS use and their sense of belonging to their friendship group. SNS users reported a stronger sense of belonging to their friendship group than non‐users, but this was found only among older boys. Furthermore, among boy SNS users, a positive linear relationship was found between the intensity of usage and feelings of belonging. No significant relationships were found for girls. These findings suggest that boys who use these sites are gaining friendship benefits over and above those boys who are non‐users or low‐intensity users. Longitudinal studies should investigate the causal relationships between SNS use and social effects within this age group. 相似文献

ABSTRACT Multiple experimental, neuropsychological, and individual differences studies indicated that faces are processed (e.g. perceived and memorized) differently from non-face objects. It was suggested that face specificity is a result of configural processing which is different from a rather part-based processing of other objects. In this research, we investigated the specificity of face cognition in terms of processing style. To this aim, we estimated Time-on-Task Effects (ToTEs) that allow inferring the level of automaticity of face and house processing. We collected data from 219 participants by applying four perception and recognition tasks. Generalized linear mixed-effects modelling was used to estimate fixed and random effects. Random slopes were interpreted as individual differences in ToTEs. Findings suggested that in the majority of tasks, face processing was dissociable from the processing of non-face objects. Thereby, these results offer a new perspective on the nature of differences in face and object processing. 相似文献
