Facebook’s emotional consequences: Why Facebook causes a decrease in mood and why people still use it

Abstract Facebook is the world’s most popular online social network and used by more than one billion people. In three studies, we explored the hypothesis that Facebook activity negatively affects people’s emotional state. A first study shows that the longer people are active on Facebook, the more negative is their mood afterwards. The second study provides causal evidence for this effect by showing that Facebook activity leads to a deterioration of mood compared to two different control conditions. Furthermore, it was demonstrated that this effect is mediated by a feeling of not having done anything meaningful. With such negative outcomes for its users, the question arises as to why so many people continue to use Facebook on a daily basis. A third study suggests that this may be because people commit an affective forecasting error in that they expect to feel better after using Facebook, whereas, in fact, they feel worse.

Bitter Taste Causes Hostility

The present research tested the novel hypothesis that bitter taste increases hostility. Theoretical background formed the intimate link of the taste-sensory system to the visceral system, with bitter intake typically eliciting a strong aversion response. Three experiments using differential bitter and control stimuli showed that hostile affect and behavior is increased by bitter taste experiences. Specifically, participants who consumed a bitter (vs. control) drink showed an increase in self-reported current hostility (Experiment 1), in hypothetical aggressive affect and hypothetical aggressive behavior (Experiment 2) and in actual hostile behavior assessed using a well-established method for non-physical laboratory aggression (Experiment 3). Furthermore, the effect occurred not only when participants were previously provoked (Experiments 2 and 3) but also when no provocation preceded (Experiment 1 and 3). Importantly, stimulus aversiveness and intensity did not influence the effects observed, ruling them out as explanations. Alternative interpretative frameworks and limitations are discussed.

Lifetime experience with (classic) psychedelics predicts pro-environmental behavior through an increase in nature relatedness:

In a large-scale (N = 1487) general population online study, we investigated the relationship between past experience with classic psychedelic substances (e.g. LSD, psilocybin, mescaline), nature relatedness, and ecological behavior (e.g. saving water, recycling). Using structural equation modeling we found that experience with classic psychedelics uniquely predicted self-reported engagement in pro-environmental behaviors, and that this relationship was statistically explained by people’s degree of self-identification with nature. Our model controlled for experiences with other classes of psychoactive substances (cannabis, dissociatives, empathogens, popular legal drugs) as well as common personality traits that usually predict drug consumption and/or nature relatedness (openness to experience, conscientiousness, conservatism). Although correlational in nature, results suggest that lifetime experience with psychedelics in particular may indeed contribute to people’s pro-environmental behavior by changing their self-construal in terms of an incorporation of the natural world, regardless of core personality traits or general propensity to consume mind-altering substances. Thereby, the present research adds to the contemporary literature on the beneficial effects of psychedelic substance use on mental wellbeing, hinting at a novel area for future research investigating their potentially positive effects on a societal level. Limitations of the present research and future directions are discussed.

Increasing wealth inequality may increase interpersonal hostility: The relationship between personal relative deprivation and aggression

Abstract In most Western societies, wealth inequality is increasing, which in turn could increase people’s belief that one’s standing is relatively disadvantaged. Based on relative deprivation theory, we argue that such an experience of personal relative deprivation should causally lead to greater interpersonal hostility. Indeed, three experiments show that participants in a personal relative deprivation condition reported higher levels of aggressive affect and behaved more aggressively than participants in a personal relative gratification condition. Compared to a control condition, participants experiencing personal relative deprivation were more aggressive rather than participants experiencing personal relative gratification being less aggressive. However, personal relative deprivation increased aggressive behavior only toward targets that were the source for participants’ experience of disadvantage, but it did not increase aggression toward neutral targets.

Does Exonerating an Accused Researcher Restore the Researcher's Credibility?

Scientific misconduct appears to be on the rise. However, an accused researcher may later be exonerated. The present research examines to what extent participants adhere to their attitude toward a researcher who allegedly committed academic misconduct after learning that the researcher is innocent. In two studies, participants in an exoneration and an uncorrected accusation condition learned that the ethics committee of a researcher’s university demanded the retraction of one of the researcher’s articles, whereas participants in a control condition did not receive this information. As intended, this manipulation led to a more favorable attitude toward the researcher in the control compared to the exoneration and the uncorrected accusation conditions (pre-exoneration attitude). Then, participants in the exoneration condition learned that the researcher was exonerated and that the article was not retracted. Participants in the uncorrected accusation and the control condition were not informed about the exoneration. Results revealed that the exoneration effectively worked, in that participants in the exoneration condition had a more favorable attitude (post-exoneration attitude) toward the researcher than did participants in the uncorrected accusation condition. Moreover, the post-exoneration attitude toward the researcher was similar in the exoneration and the control conditions. Finally, in the exoneration condition only, participants’ post-exoneration attitude was more favorable than their pre-exoneration attitude. These findings suggest that an exoneration of an accused researcher restores the researcher’s credibility.

Does Low (vs. High) Subjective Socioeconomic Status Increase Both Prosociality and Aggression

Previous research has shown that people of low subjective socioeconomic status (SES) are more likely to experience compassion and provide help to others than people of high SES. However, low subjective SES also appears to be related to more hostile and aggressive responding. Given that prosociality is typically an antagonist of aggression, we examined whether low subjective SES individuals could be indeed more prosocial and antisocial. Five studies – two correlational, three experimental – found that low subjective SES was related to increased aggression. In contrast, subjective SES was not negatively related to trait and state measures of prosociality.

Getting connected: intergroup contact on Facebook

ABSTRACT One correlational study examined whether virtual contact via Facebook is positively related to intergroup relations. The followers of two online campaigns from Iran and Israel—whose countries have been in a politically hostile relationship since the 1980s—indicated the amount of direct and indirect virtual (Facebook) and real-life outgroup contact they have had, a number of quality and affective judgments about that contact, and completed an affective prejudice measure about the respective outgroup. Overall, contact was negatively associated with affective prejudice, providing support for the contact hypothesis in a specific and exclusively virtual setting with citizens of hostile nations. Previously experienced real-life contact did not moderate the results, suggesting that virtual contact has an independent link to positive outgroup attitudes.

Original dataset used in the article “Does Pokémon Go lead to a more physically active life style?”

The data presented in this article are related to the research article entitled “Does Pokémon Go lead to a more physically active life style?” (Gabbiadini et al., in press) [1]. In the study, 981 individuals completed a web survey, in which frequency of Pokémon Go usage, overall physically active behavior, and amount of Pokémon Go related physical activity were measured. Regression analyses revealed that Pokémon Go related physical activity significantly reversed the positive effects of the app on participants’ overall physically active behavior, suggesting that the mere adoption of the app does not reliably change people׳s behavior in general. The increase in physical activity levels is rather explained by the exercise required by the game. The data set is made publicly available to enable critical or extended analyzes.
