The power of human touch: Physical contact improves performance in basketball free throws

How pervasive is the power of human touch? Physical touch by other humans shows social support and alleviates stress - stress that may otherwise interfere with performance in athletic tasks. We argue that physical touch improves performance in highly stressful situations: free throws in basketball. In two studies (Ntotal = 60 NCAAW games, ktotal = 835 free throw tandems), we assessed how often teammates touched the shooting player (e.g., a tap on the shoulder) in between shooting two free throws. We find that the extent of touch (i.e., being touched by 0, 1, 2, 3, or all 4 teammates) after the first free throw predicted success with the second free throw, but only when players missed the first free throw (integrated data analysis: main effect hand taps: b = 0.47, p = .021; main effect first free throw: b = 1.36, p = .019; interaction effect: b = -0.55, p = .024). We argue that this means that teammates' support expressed in physical touch helps particularly when stress levels are already high. Results are robust when controlling for players' skill level, home versus away games, point difference, and remaining playing time. More frequent touch was also tendentially associated with teams' season success (ACC-teams only, main effect of hand taps: b = -0.42, p = .062). Physical touch thus indeed boosts performance under stress, superseding a range of other factors, likely also in other team sports and interpersonal relationships.

When and why we ostracize others: Motivated social exclusion in group contexts

Research on ostracism has mostly focused on ostracized targets' reactions to being excluded and ignored. In contrast, the ostracizing sources' perspective and reasons for why individuals decide to ostracize others are still a largely unexplored frontier for empirical research. We propose two fundamental motives situated in the target's behavior that drive motivated ostracism decisions for the benefit of one's group: A perceived norm violation of the target and perceived expendability of the target for achieving group goals. Two survey studies and five experiments (total N = 2,394, all preregistered) support our predictions: When asked to recall a recent ostracism decision and the motives for it, participants reported both perceived norm violations and/or expendability of the target as motives (Study 1). Switching to the target perspective, the frequency of experienced ostracism was associated with both self-perceived norm violations and expendability (Study 2). In five experiments (Studies 3-7), participants consistently choose to ostracize targets more often when they perceived them to be either norm-violating, or inept in a skill important for the group and thus expendable. Additionally, Studies 5-7 show that strategic considerations about the requirements of the situational context influence ostracism decisions: Participants were more likely to ostracize norm-violating targets in cooperative contexts, and more likely to ostracize inept targets in performance contexts. Results have strong theoretical implications for research on ostracism and group dynamics, as well as for interventions targeting ostracism behavior: Particularly, adjusting the requirements of the situational context might be a viable option to decrease ostracism and promote inclusion in groups.

It will (never) stop hurting: Do repeated or chronic experiences of exclusion lead to hyper- or hyposensitive psychological responses?

Unlike one-time lab manipulations of exclusion, in real life, many people experience exclusion, from others and from groups, over extended periods, raising the question of whether individuals could, over time, develop hypo- or hypersensitive responses to chronic exclusion. In Study 1, we subjected participants to repeated experiences of inclusion or exclusion (three Cyberball games, time lag of three days, N = 194; 659 observations). We find that repeatedly excluded individuals become hypersensitive to inclusion, but not to exclusion. Study 2 ( N = 183) tested whether individuals with chronic experiences of real-world exclusion show hypo- or hypersensitive responses to a novel episode of exclusion. In line with Study 1, exclusion hurt to the same extent regardless of baseline levels of chronic exclusion in daily life. However, chronically excluded individuals show more psychological distress in general. We discuss theoretical and practical implications for dealing with chronically excluded individuals and groups.

Depressed and excluded: Do depressive symptoms moderate recovery from ostracism?

BACKGROUND

Prior studies show that depressed individuals react with more immediate reflexive need threat to ostracism than healthy controls. However, it remains unclear whether the observed difference between depressed individuals and healthy controls is caused by ostracism. To find out, the exclusion condition needs to be compared to a baseline condition: inclusion.

METHODS

We assessed depressive symptoms in N = 426 participants in an experimental study. Participants were included or excluded in Cyberball and indicated both their immediate reflexive need satisfaction level and their reflective need satisfaction level several minutes later to assess recovery.

RESULTS

Being excluded decreased reflexive need satisfaction levels for all participants. At the same time, the strength of depressive symptoms negatively predicted reflexive and reflective need satisfaction and was associated with slower recovery. Importantly, no moderation was observed: individuals with more depressive symptoms reported reduced need satisfaction levels regardless of being included or excluded in Cyberball.

LIMITATIONS

The present findings were obtained with one paradigm only, albeit the most commonly used one: Cyberball. Depressive symptoms were assessed as self-report; future studies may wish to replicate the effects using structured clinical interviews.

CONCLUSIONS

Depressive symptoms come with lowered need satisfaction levels, irrespective of whether individuals are socially excluded or included. Clinical practitioners should be aware of the relationship between chronic need threat and depression in order to help their patients overcome it.
