@biogarage Jamil Bhanji, Mauricio Delgado: The social brain and reward: social informat... - 0 views

  •  
    "This research provides an understanding of the neural basis for social behavior from the perspective of how we evaluate social experiences and how our social interactions and decisions are motivated. We review research addressing the common neural systems underlying evaluation of social and nonsocial rewards. The human striatum, known to play a key role in reward processing, displays signals related to a broad spectrum of social functioning, including evaluating social rewards, making decisions influenced by social factors, learning about social others, cooperating, competing, and following social norms.

How your memories can be twisted under social pressure | KurzweilAI - 1 views

  •  
    Listen up, Facebook and Twitter groupies: how easily can social pressure affect your memory? Very easily, researchers at the Weizmann Institute and University College London have proved, and they think they even know what part of the brain is responsible. The participants conformed to the group on these "planted" responses, giving incorrect answers nearly 70% of the time. Volunteers watched a documentary film in small groups. Three days later, they returned to the lab individually to take a memory test, answering questions about the film. They were also asked how confident they were in their answers. They were later invited back to the lab to retake the test. This time, the subjects were also given supposed answers of the others in their film-viewing group (along with social-media-style photos) while being scanned in a functional MRI (fMRI) that revealed their brain activity. Is most of what you know false? Planted among these were false answers to questions the volunteers had previously answered correctly and confidently. The participants conformed to the group on these "planted" responses, giving incorrect answers nearly 70% of the time. To determine if their memory of the film had actually undergone a change, the researchers invited the subjects back to the lab later to take the memory test once again, telling them that the answers they had previously been fed were not those of their fellow film watchers, but random computer generations. Some of the responses reverted back to the original, correct ones, but get this: despite finding out the scientists messed with their minds, close to half of their responses remained erroneous, implying that the subjects were relying on false memories implanted in the earlier session. An analysis of the fMRI data showed a strong co-activation and connectivity between two brain areas: the hippocampus and the amygdala. Social reinforcement could act on the amygdala to persuade our brains to replace a strong memory wi

Tung, Barreiro, Johnson, Gilad Social stress affects immune system gene expression in m... - 0 views

  •  
    "Previous research on rhesus macaques discovered that social rank influenced components of the stress response, brain, and immune system. With gene chip technology for measuring the expression of over 6,000 different genes, Tung, Gilad and colleagues at Yerkes, Emory University, and Johns Hopkins looked for the first time in primates at the effects of social rank on genetic function. Comparing 49 different female monkeys of different rank revealed significant changes in the expression of 987 genes, including 112 genes associated with immune system function. The result fits with data in monkeys where low rank and chronic stress lead to compromised immune function, and, more loosely, with human studies linking low socioeconomic status and high social stress to elevated disease risk."

    "And the more urgent the issue, the more people want to remain unaware, according to a paper published online in APA's Journal of Personality and Social Psychology. "These studies were designed to help understand the so-called 'ignorance is bliss' approach to social issues," said author Steven Shepherd, a graduate student with the University of Waterloo in Ontario. "The findings can assist educators in addressing significant barriers to getting people involved and engaged in social issues."

    "It is a widely accepted principle of distributive justice that goods should be distributed to individuals according to their contribution, i.e., people should receive equal pay for equal work (equity principle)...Recently, neuroscientific studies have begun to address neural processes underlying social and economic phenomena like e.g., reactions to norm violations, status concerns, and reactions to unfair behavior. These studies have convergingly identified brain regions that are important for these aspects of social behavior. One consistent finding is that activations of the dopaminergic mesolimbic ("reward") system, especially the nucleus accumbens (NAcc) do not exclusively reflect material self-interest, but also social aspects

Web of Popularity, Achieved by Bullying - NYTimes.com - 0 views

  •  
    For many teenagers navigating the social challenges of high school, the ultimate goal is to become part of the "popular" crowd. But new research suggests that the road to high school popularity can be treacherous, and that students near the top of the social hierarchy are often both perpetrators and victims of aggressive behavior involving their peers. The latest findings, being published this month in The American Sociological Review, offer a fascinating glimpse into the social stratification of teenagers. The new study, along with related research from the University of California, Davis, also challenges the stereotypes of both high school bully and victim

Marta Soares Tactile stimulation lowers stress in fish : Nature Communications : Nature... - 0 views

    "In humans, physical stimulation, such as massage therapy, reduces stress and has demonstrable health benefits. Grooming in primates may have similar effects but it remains unclear whether the positive effects are due to physical contact or to its social value. Here we show that physical stimulation reduces stress in a coral reef fish, the surgeonfish Ctenochaetus striatus. These fish regularly visit cleaner wrasses Labroides dimidiatus to have ectoparasites removed. The cleanerfish influences client decisions by physically touching the surgeonfish with its pectoral and pelvic fins, a behaviour known as tactile stimulation. We simulated this behaviour by exposing surgeonfish to mechanically moving cleanerfish models. Surgeonfish had significantly lower levels of cortisol when stimulated by moving models compared with controls with access to stationary models. Our results show that physical contact alone, without a social aspect, is enough to produce fitness-enhancing benefits, a situation so far only demonstrated in humans"

    "My link was shared by Bora Zivkovic, whose network is immense. And in turn, the link was shared by Twitter users in Greece, Germany, Belgium and throughout the United States. In the end, the blogpost wound up with 109 readers on January 22nd - with about 50 via Twitter, 26 via Facebook, and others via LinkedIn and elsewhere. When each person shared the link with her or his network, the momentum is carried forward, pushing out to new networks and new degrees of separation. Social sharing is a bit like the emails you would get forwarded by your relatives (you know, those emails). The deeper you scroll down the thread, the less sender names you recognize. But with Twitter, and using analytics like WordPress or Google, you can actually trace how a little link travels through different social networks, and eventually back to your website. Also, because many people embed a small bio or website link in their Twitter profile, I can quickly see who has retweeted and read my link. I can read their tweets to get an idea of their profession and passions,"

Our Social Nature: The Surprising Science of Smiles | Wired Science | Wired.com - 0 views

  •  
    All hail the powerful smile. The right smile, at the right time, wins friends and calms enemies. The smile held for too long, not long enough, flashed too intensively or too dimly, arouses suspicion, fear or anger. Far from being a straightforward show of joy, the language of smiles is filled with subtlety: a meld of our inner state, surroundings, social training, conscious and unconscious.

Boys reach sexual maturity younger and younger: Phase between being physically but not ... - 0 views

  •  
    ScienceDaily (Aug. 19, 2011) - Boys are maturing physically earlier than ever before. The age of sexual maturity has been decreasing by about 2.5 months each decade at least since the middle of the 18th century. Joshua Goldstein, director of the Max Planck Institute for Demographic Research in Rostock (MPIDR), has used mortality data to demonstrate this trend, which until now was difficult to decipher. What had already been established for girls now seems to also be true for boys: the time period during which young people are sexually mature but socially not yet considered adults is expanding.

    Kumaran D et al., The Emergence and Representation of Knowledge about Social and Nonsocial Hierarchies, 2012, Neuron, doi: 10.1016/j.neuron.2012.09.035 Eine neue Studie, die in dem Journal Neuron veröffentlicht wurde, deckt auf, wie das Gehirn Informationen darüber abspeichert, wer in einer Gruppe das ‚Sagen' hat. Die Studie, die gemeinsam von Wissenschaftlern des Instituts für Kognitive Neurologie und Demenzforschung der Universität Magdeburg (IKND), des Deutschen Zentrums für Neurodegenerative Erkrankungen (DZNE, Standort Magdeburg) und der University College London (UCL) durchgeführt wurde, zeigt, dass Menschen zum Lernen von sozialen Rangfolgen einen bestimmten Teil des Gehirns brauchen. Die Größe dieses Gehirnareals sagt voraus, wie gut jemand soziale Rangfolgen lernen und einschätzen kann. Menschen und andere Primaten sind bemerkenswert gut darin, sich gegenseitig innerhalb einer sozialen Hierarchie einzuordnen. „Diese Fähigkeit ist überlebensnotwendig, weil sie hilft, Konflikte zu vermeiden und vorteilhafte Koalitionspartner zu finden. Allerdings wissen wir überraschend wenig darüber, wie das Gehirn dies steuert", sagt der Neurowissenschaftler Prof. Emrah Düzel.
