Threats to belonging on Facebook: lurking and ostracism

We examined two threats to belonging and related needs on Facebook: lurking (Study 1) and ostracism (Study 2). In Study 1, participants were either allowed or not allowed to share information on Facebook for 48 hours. Those who were not allowed to share information had lower levels of belonging and meaningful existence. In Study 2, participants engaged in a laboratory-based Facebook activity. Half of the profiles were set up so that participants would not receive any feedback on their status updates. Participants who did not receive feedback on their updates had lower levels of belonging, self-esteem, control, and meaningful existence. Together, these findings indicate that a lack of information sharing and feedback can threaten belonging needs.

Predicting Facebook Users’ Online Privacy Protection: Risk, Trust, Norm Focus Theory, and the Theory of Planned Behavior

ABSTRACT The present research adopts an extended theory of the planned behavior model that included descriptive norms, risk, and trust to investigate online privacy protection in Facebook users. Facebook users (N = 119) completed a questionnaire assessing their attitude, subjective injunctive norm, subjective descriptive norm, perceived behavioral control, implicit perceived risk, trust of other Facebook users, and intentions toward protecting their privacy online. Behavior was measured indirectly 2 weeks after the study. The data show partial support for the theory of planned behavior and strong support for the independence of subjective injunctive and descriptive norms. Risk also uniquely predicted intentions over and above the theory of planned behavior, but there were no unique effects of trust on intentions, nor of risk or trust on behavior. Implications are discussed.

The dual-pathway model of collective action: Impacts of types of collective action and social identity:

In three experiments, we manipulated procedural fairness (Experiment 1) and group-based anger and group efficacy (Experiments 2 and 3) to investigate the independent pathways of anger and efficacy for collective action in China. In Experiment 3 we also examined pathways to “soft” (low-cost) and “hard” (high-cost) collective action. Our results supported the dual-pathway model of collective action: group-based anger and perceived group efficacy independently predicted collective action intentions to protest against increased school fees and unhygienic cafeteria conditions for Chinese university students. Group-based anger predicted soft collective action intentions; both anger and efficacy predicted hard collective action intentions. Identification with the disadvantaged group was found to moderate the problem-focused coping pathway for hard collective action intentions. For high but not low identifiers, manipulated group efficacy predicted hard collective action intentions. We discuss our findings with specific reference to collective action research in China.

Social connectedness improves public mental health: Investigating bidirectional relationships in the New Zealand attitudes and values survey

Background: The importance of social connectedness in supporting public mental health is well established. However, the reverse causal pathway (that psychological ill-health leads to reduced social connectedness) remains a dominant perspective among mental health practitioners. Our analysis aimed to provide a rigorous test of the directionality of this relationship. Method: A cross-lagged panel analysis of a large longitudinal national probability sample (N ≈ 21,227), the New Zealand Attitudes and Values Survey, was used to assess the bidirectional longitudinal relationship between social connectedness and mental health, controlling for baseline levels of both variables and demographics. Results: Social connectedness was found to be a stronger and more consistent predictor of mental health year-on-year than mental health was of social connectedness. Conclusion: These results further demonstrate how the psychological resources conferred by social connectedness can act as a ‘social cure’ for psychological ill-health, and provide the strongest evidence to date for the direction of this relationship in the general community.

A Yellow Filter Improves Response Times to Low-Contrast Targets and Traffic Hazards

Purpose Anecdotal evidence suggests that some sunglass users prefer yellow tints for outdoor activities, such as driving, and research has suggested that such tints improve the apparent contrast and brightness of real-world objects. The aim of this study was to establish whether yellow filters resulted in objective improvements in performance for visual tasks relevant to driving. Methods Response times of nine young (age [mean ± SD], 31.4 ± 6.7 years) and nine older (age, [mean ± SD], 74.6 ± 4.8) adults were measured using video presentations of traffic hazards (driving hazard perception task) and a simple low-contrast grating appeared at random peripheral locations on a computer screen. Response times were compared when participants wore a yellow filter (with and without a linear polarizer) versus a neutral density filter (with and without a linear polarizer). All lens combinations were matched to have similar luminance transmittances (˜27%). Results In the driving hazard perception task, the young but not the older participants responded significantly more rapidly to hazards when wearing a yellow filter than with a luminance-matched neutral density filter (mean difference, 450 milliseconds). In the low-contrast grating task, younger participants also responded more quickly for the yellow filter condition but only when combined with a polarizer. Although response times increased with increasing stimulus eccentricity for the low-contrast grating task, for the younger participants, this slowing of response times with increased eccentricity was reduced in the presence of a yellow filter, indicating that perception of more peripheral objects may be improved by this filter combination. Conclusions Yellow filters improve response times for younger adults for visual tasks relevant to driving.
