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.

Declining Loneliness Over Time: Evidence From American Colleges and High Schools

We examined changes in loneliness over time. Study 1 was a cross-temporal meta-analysis of 48 samples of American college students who completed the Revised UCLA Loneliness Scale (total N = 13,041). In Study 1, loneliness declined from 1978 to 2009 (d = −0.26). Study 2 used a representative sample of high school students from the Monitoring the Future project (total N = 385,153). In Study 2, loneliness declined from 1991 to 2012. Declines were similar among White students (d = −0.14), Black students (d = −0.17), male students (d = −0.11), and female students (d = −0.11). Different loneliness factors showed diverging trends. Subjective isolation declined (d = −0.20), whereas social network isolation increased (d = 0.06). We discuss the declines in loneliness within the context of other cultural changes, including changes to group membership and personality.

Coping with causal uncertainty through alcohol use

OBJECTIVE We examined whether individuals use alcohol in order to cope with causal uncertainty (i.e., doubt about the causes of events). We predicted that higher levels of causal uncertainty would be associated with stronger coping motives, which, in turn, would predict more problems with alcohol. We also examined age as a moderator, with the expectation that stronger associations would be found among younger adults. METHOD Two hundred sixty-three adults who drank alcohol at least occasionally completed questionnaires assessing causal uncertainty, correlates of causal uncertainty, motives for drinking, alcohol consumption, and alcohol-related problems. RESULTS Moderated mediation analyses revealed that among younger adults, causal uncertainty had a significant indirect effect on problems with alcohol through coping with depression and enhancement motives. Among older adults, there were no significant associations between causal uncertainty and alcohol motives or problems. The effect via the coping with depression motive held even after controlling for alcohol consumption and the major cognitive and affective correlates of causal uncertainty, whereas the effect via the enhancement motive became nonsignificant. CONCLUSIONS Our results are consistent with the idea that younger adults use alcohol to cope with causal uncertainty, putting them at greater risk for alcohol-related problems.

The burden of online friends: the effects of giving up Facebook on stress and well-being

ABSTRACT People occasionally choose to cut themselves off from their online social network by taking extended breaks from Facebook. This study investigated whether abstaining from Facebook reduces stress but also reduces subjective well-being because of the resulting social disconnection. Participants (138 active Facebook users) were assigned to either a condition in which they were instructed to give up Facebook for 5 days or continue to use Facebook as normal. Perceived stress and well-being, as well as salivary cortisol, were measured before and after the test period. Relative to those in the Facebook Normal condition, those in the No Facebook condition experienced lower levels of cortisol and life satisfaction. Our results suggest that the typical Facebook user may occasionally find the large amount of social information available to be taxing, and Facebook vacations could ameliorate this stress—at least in the short term.

Replication Rate, Framing, and Format Affect Attitudes and Decisions about Science Claims

A series of five experiments examined how the evaluation of a scientific finding was influenced by information about the number of studies that had successfully replicated the initial finding. The experiments also tested the impact of frame (negative, positive) and numeric format (percentage, natural frequency) on the evaluation of scientific findings. In Experiments 1 through 4, an attitude difference score served as the dependent measure, while a measure of choice served as the dependent measure in Experiment 5. Results from a diverse sample of 188 non-institutionalized U.S. adults (Experiment 2) and 730 undergraduate college students (Experiments 1, 3, and 4) indicated that attitudes became more positive as the replication rate increased and attitudes were more positive when the replication information was framed positively. The results also indicate that the manner in which replication rate was framed had a greater impact on attitude than the replication rate itself. The large effect for frame was attenuated somewhat when information about replication was presented in the form of natural frequencies rather than percentages. A fifth study employing 662 undergraduate college students in a task in which choice served as the dependent measure confirmed the framing effect and replicated the replication rate effect in the positive frame condition, but provided no evidence that the use of natural frequencies diminished the effect.

Attitudes toward others depend upon self and other causal uncertainty

People who are high in causal uncertainty doubt their own ability to understand the causes of social events. In three studies, we examined the effects of target and perceiver causal uncertainty on attitudes toward the target. Target causal uncertainty was manipulated via responses on a causal uncertainty scale in Studies 1 and 2, and with a scenario in Study 3. In Studies 1 and 2, we found that participants liked the low causal uncertainty target more than the high causal uncertainty target. This preference was stronger for low relative to high causal uncertainty participants because high causal uncertainty participants held more uncertain ideals. In Study 3, we examined the value individuals place upon causal understanding (causal importance) as an additional moderator. We found that regardless of their own causal uncertainty level, participants who were high in causal importance liked the low causal uncertainty target more than the high causal uncertainty target. However, when participants were low in causal importance, low causal uncertainty perceivers showed no preference and high causal uncertainty perceivers preferred the high causal uncertainty target. These findings reveal that goal importance and ideals can influence how perceivers respond to causal uncertainty in others.

The effects of primed causal uncertainty and causal importance on persuasion

We examined the effects of temporarily accessible causal uncertainty and causal importance on persuasion. Participants completed a scrambled sentence priming task, read strong or weak, causal or noncausal arguments, and then reported their attitudes. We found that participants primed with high levels of causal uncertainty and importance thought carefully about the causal arguments. They were more persuaded by the strong compared to weak causal arguments, and this effect was partially mediated by the favorability of their message-relevant thoughts. Participants primed with high causal uncertainty and low causal importance were more persuaded by strong compared to weak noncausal arguments, but this effect was not mediated by thoughts. We discuss the implications of these findings for the causal uncertainty and persuasion literatures.

The effect of ad hominem attacks on the evaluation of claims promoted by scientists

Two experiments were conducted to determine the relative impact of direct and indirect (ad hominem) attacks on science claims. Four hundred and thirty-nine college students (Experiment 1) and 199 adults (Experiment 2) read a series of science claims and indicated their attitudes towards those claims. Each claim was paired with one of the following: A) a direct attack upon the empirical basis of the science claim B) an ad hominem attack on the scientist who made the claim or C) both. Results indicate that ad hominem attacks may have the same degree of impact as attacks on the empirical basis of the science claims, and that allegations of conflict of interest may be just as influential as allegations of outright fraud.

Positive affect increases secondary control among causally uncertain individuals

Secondary control (acceptance of and adjustment to negative events) is thought to promote positive affect. We examined the opposite path: could positive affect increase secondary control, particularly among individuals high in causal uncertainty, who stand to benefit from it the most? In two studies, participants completed a causal uncertainty scale, thought about a problem while listening to affect-inducing music or no music, and then completed items that assessed secondary control. In Study 1, the music induced positive or negative affect. In Study 2, the music induced affect that was high or low in activation and positive or negative in valence. In both studies, we found that positive affect-inducing music increased secondary control among high causal uncertainty participants. Furthermore, trait affect did not account for the effects of causal uncertainty, and music did not influence primary control. These findings show that secondary control can fluctuate as a function of state affect.

The role of group size in reactions to ostracism and inclusion

Three experiments examined the effects of group size on reactions to ostracism and inclusion. Participants engaged in an online introduction activity with 2 or 6 other people and received likes from everyone (inclusion) or no one (ostracism). In Studies 1 and 2, group size had a significant effect on need satisfaction only when participants were ostracized, with larger groups threatening needs to a greater extent. These effects were evident during and immediately after the task, but not after a reflection period and delay. In Study 3, being ostracized by a larger group increased sadness and anger only when ostracism was public. Together, these results indicate that people react more negatively to ostracism by larger groups, but do not reap greater benefits in terms of need satisfaction or affect when included by larger groups. Implications for the ostracism literature and social media use are discussed.
