Glucose Increases Risky Behavior and Attitudes in People Low in Self-Control: A pilot study

People low in self-control have a strong proclivity toward risk-taking. Risk-taking behavior provides an opportunity to obtain some form of reward. Glucose, on the other hand, seems to facilitate reward and goal-directed behavior. In a pilot study executed in the laboratory, we investigated whether consuming a glucose drink would increase risky behavior and attitudes in people low in self-control. Our findings revealed that a dose of glucose compared to placebo increased risk-taking on a behavioral and cognitive level in participants low in self-control but not in participants high in self-control. The findings may shed some light on the psychological underpinnings of glucose: By showing glucose's association with high-risk behavior, they support the assumption of glucose driving a goal-directed motivation

Regaining power: How feelings of exclusion during COVID-19 are associated with radicalism among critics of containment policies

Past experimental research has shown that social exclusion can be linked with radicalism. During the COVID-19 pandemic, feelings of social isolation and loneliness rose, just like protests and violence against national anti-COVID-19 measures did. Based on these observations, we hypothesized that feelings of exclusion induced by measures to contain the spread of COVID-19 were associated with radicalism intentions to illegally and violently fight COVID-19-related regulations among critics of the containment policies (Hypothesis 1). Moreover, we expected that radicalism intentions against COVID-19-related regulations fortified needs deprived by social exclusion (Hypothesis 2). Studying a sample of individuals who opposed the measures to contain the spread of COVID-19 (N = 171), we found evidence for both hypotheses: Results revealed that feelings of social exclusion induced by COVID-19 containment measures predicted radicalism intentions. Moreover, the relationship between exclusion and radicalism was associated with fortifying power issues. Political opinion did not moderate these effects. These data replicate the exclusion-radicalism link in the COVID-19 crisis and add one more factor that may have promoted radical developments during that time. Fortifying feelings of power, radicalism appeared to foster well-being, though at a high political price

Rejection Via Video The Impact of Observed Group and Individual Rejection

This study introduces an easy-to-implement, controlled, vivid, and functional rejection paradigm. Participants empathized with the protagonist of a video who was rejected or accepted individually or as part of a group. In the rejection condition, more perceived exclusion and lower basic need fulfillment were reported. The paradigm also induced nuance in situational factors: Observing somebody being rejected as part of a group led to less pronounced reactions than individual rejection. The video-based rejection paradigm taps into the less studied area of group rejection and offers a new method to test established and novel theoretical predictions

Taking the focus away from the self: low individualism mediates the effect of oxytocin on creativity

Recently, it has been shown that the hormone oxytocin can enable creative cognition. The aim of this investigation was to examine the psychological mechanism via which oxytocin influences creativity. Two opposing explanatory approaches suggested by previous research were investigated: It was predicted that the effect of oxytocin on creativity would be determined by low versus high individualism, especially in people with low levels of anxiety. Participants filled out an anxiety questionnaire and intranasally administered oxytocin or a placebo. After a 40-min waiting period, they performed a creativity task and indicated their level of individualism. Participants with low levels of anxiety showed heightened creative potential under oxytocin, and this relationship was mediated by low individualism. The results could not be explained by changes in the participants’ affective state. The findings underscore the moderating role of dispositional factors and reveal an important factor to understand the role of oxytocin in human behavior

Exclude Me If You Can – Cultural Effects on the Outcomes of Social Exclusion

We examined how individualistic versus collectivistic cultural backgrounds affected the psychological experience of social exclusion. We found that Turkish, Chinese, and Indian participants (collectivistic background) differed in their experience of social exclusion from German participants (individualistic background): German participants experienced lower fulfillment of psychological needs in response to social exclusion, whereas Turkish, Chinese, and Indian participants were affected to a lesser extent (Turkey, India, Hong Kong) or not at all (mainland China) by social exclusion manipulations. Testing two different explanatory mechanisms in Study 3, we found that the difference in dealing with social exclusion was not associated with activating social representations in participants with collectivistic background but with exclusion being associated with more threat in participants with individualistic background. In Study 4, cultural differences emerged also on the physiological level: German participants’ heart rates were increased when excluded, whereas Chinese participants showed no change in heart rate during exclusion. The results are discussed regarding their implications for the role of self-construal and culture when dealing with the threat of social exclusion
