Wie unsere Psyche Schmerzen beeinflusst Schmerz nervt, ist aber wichtig. Die Schmerzforscherin Susanne Becker erklärt, wie Schmerz funktioniert und wie wir ihn beeinflussen können.

Einige unserer Veranstaltungen gibt's regelmäßig im Podcast #Hörsaal vom Deutschlandfunk Nova zu hören. Im neuen Beitrag geht's um Schmerzen.
Sie sind lästig, niemand hat sie gern. Dennoch brauchen wir sie. Sie sind ein Warnsignal des Körpers und ein Zeichen von Wachstum - Stichwort Muskelkater. 1/2

Stress macht aggressiv und großzügig Stress macht uns oft unfreundlich und aggressiv, aber auch großzügig und hilfsbereit. Diese beiden Reaktionen widersprechen sich nur scheinbar.

#Stress führt häufig dazu, dass wir gereizt(er) sind – er kann uns aber auch hilfsbereit oder großzügig machen.
In der neuen Folge des Podcasts #Hörsaal vom Deutschlandfunk Nova geht es um das Thema Stress mit Prof. Tobias @kalenscher.bsky.social. ⤵️ 1/2

Stress bestimmt den Alltag vieler Menschen. Doch wie wirkt er sich im sozialen Miteinander aus? Die Vergleichende Psychologie kommt zu verschiedenen Ergebnissen - von Aggressivität bis hin zu Hilfsbereitschaft.
Verantwortlich dafür sind verschiedene Botenstoffe im Gehirn. 1/3

Aber was genau passiert in unserem Körper, wenn wir gestresst sind? Und wie wirkt sich Stress auf unser soziales Miteinander aus?
In unserer Reihe “Forschung im Fokus” blickt Tobias Kalenscher (@kalenscher.bsky.social), Professor für Vergleichende Psychologie an der @hhu.de, auf das Thema. 2/3

Us Versus Them Does stress make us more aggressive or more helpful? New research suggests it does both. This dual effect may drive growing societal polarization and the persistence of conflict.

New blog post! I summarize our recent paper (www.pnas.org/doi/10.1073/...) how stress concurrently fosters ingroup support and outgroup competition, and what this has to do with societal polarization and conflict.

Stress enhances cooperation within groups while simultaneously increasing hostility toward outsiders Stress is known to affect social behavior, but how exactly it does so is still unclear. In the past, its effects were contradictory: stress has been linked to either more aggressive reactions (fight-o...

How stress strengthens group bonds—and fuels intergroup conflict Why do violent conflicts between groups persist—even when all sides suffer as a result? Researchers from psychology and medicine at Heinrich Heine University Düsseldorf (HHU) have now examined the dual effect of physiological stress messengers on social behavior in intergroup conflicts.

Acute stress can enhance cooperation within groups while simultaneously increasing hostility toward outsiders, driven by distinct neurochemical pathways. doi.org/g9s8sw

Our results, thus, offer a neurobiological mechanism for the populist playbooks how fear and stress contributes to rising polarization in society. It also sheds light on why intergroup conflicts escalate, and why they persist even among rational actors. Link: www.pnas.org/doi/10.1073/...

3/4
Thus, we show that this dual effect (ingroup altruism plus outgroup aggression) amplifies an “us-vs.-them” mentality. This helps explain how fear-based political messaging may trigger group cohesion and, at the same time, fuel hostility toward outsiders.

2/4
In our new study, we show:
🧪 Cortisol (main stress hormone) promotes cooperation with the ingroup
🧪 Noradrenaline (arousal transmitter) drives hostility toward outgroups, even at personal costs
Stress doesn't just make you aggressive or altruistic. It shapes who you support or oppose.

1/4
New paper in @pnas.org! How does stress affect our social decisions in conflict? More aggression (fight-or-flight)? Or more altruism (tend-and-befriend)? Our new study suggests: it’s not either/or, stress promotes both at once, depending on the neurochemical balance and the social context. 🧠

based on social-emotional distance between individuals. This finding is consistent with theoretical ideas highlighting the BLA’s importance in balancing self- and other-regarding motives, underlining its crucial role in model-based social cognition.

varying in social-emotional distance. We found that, while BLA was not essential for prosociality per se, it played a critical role in calibrating generosity depending how socially close or distant the participants felt to the other people. Hence, BLA fine-tuned prosocial behavior

We studied South-African individuals with the very rare Urbach-Wiethe disease who have selective damage to the BLA. Urbach-Wiethe subjects and matched controls played a social discounting game – a game in which they could distribute money between themselves and other people

Why are we generous to some people but not to others? And which brain mechanisms govern our decision to be generous toward others? In our latest research, published in @pnas.org (www.pnas.org/doi/10.1073/...), we report steeper social discounting after human basolateral amygdala (BLA) lesions.
