Människor uppför sig även utan bestämda regler

Fundamentally people behave in a social and rather compassionate and ”good” way rather than aggressively, even without specified rules. That is the result of a study from the Institute for Science of Complex Systems at the MedUni Vienna under the leadership of Stefan Thurner and Michael Szell. They analysed the behaviour of more than 400,000 participants of the “Virtual Life” game “Pardus” on the Internet. The findings are that only two percent of all actions are aggressive, even though the game would make it easy for war-like attacks with spaceships, for example.

The game does not suggest any rules and everyone can live with their avatar (i.e. with their “game character” in the virtual world) as they choose. “And the result of this is not anarchy”, says Thurner. “The participants organise themselves as a social group with good intents. Almost all the actions are positive.

People behave socially and ’well’ even without rules

Dina minnen förändras med tiden

Turns out your memory is a lot like the telephone game, according to a new Northwestern Medicine study.

Every time you remember an event from the past, your brain networks change in ways that can alter the later recall of the event. Thus, the next time you remember it, you might recall not the original event but what you remembered the previous time. The Northwestern study is the first to show this.

“A memory is not simply an image produced by time traveling back to the original event — it can be an image that is somewhat distorted because of the prior times you remembered it,” said Donna Bridge, a postdoctoral fellow at Northwestern University Feinberg School of Medicine and lead author of the paper on the study recently published in the Journal of Neuroscience. “Your memory of an event can grow less precise even to the point of being totally false with each retrieval.”

The published study reports on Bridge’s work with 12 participants, but she has run several variations of the study with a total of 70 people. “Every single person has shown this effect,” she said. “It’s really huge.”

“When someone tells me they are sure they remember exactly the way something happened, I just laugh,” Bridge said.

The reason for the distortion, Bridge said, is the fact that human memories are always adapting.

“Memories aren’t static,” she noted. “If you remember something in the context of a new environment and time, or if you are even in a different mood, your memories might integrate the new information.”

The Marshmallow Study Revisited

For the past four decades, the ”marshmallow test” has served as a classic experimental measure of children’s self-control: will a preschooler eat one of the fluffy white confections now or hold out for two later?

Now a new study demonstrates that being able to delay gratification is influenced as much by the environment as by innate ability. Children who experienced reliable interactions immediately before the marshmallow task waited on average four times longer—12 versus three minutes—than youngsters in similar but unreliable situations.

The findings provide an important reminder about the complexity of human behavior, adds coauthor Richard Aslin, the William R. Kenan Professor of brain and cognitive sciences at the University. ”This study is an example of both nature and nurture playing a role,” he says. ”We know that to some extent, temperament is clearly inherited, because infants differ in their behaviors from birth. But this experiment provides robust evidence that young children’s action are also based on rational decisions about their environment.”

Children who experienced unreliable interactions with an experimenter waited for a mean time of three minutes and two seconds on the subsequent marshmallow task, while youngsters who experienced reliable interactions held out for 12 minutes and two seconds. Only one of the 14 children in the unreliable group waited the full 15 minutes, compared to nine children in the reliable condition.

The robust effect of manipulating the environment, conclude the authors, provides strong evidence that children’s wait times reflect rational decision making about the probability of reward. The results are consistent with other research showing that children are sensitive to uncertainly in future rewards and with population studies showing children with absent fathers prefer more immediate rewards over larger but delayed ones.

The Marshmallow Study Revisited

When I entered the emergency room that morning, my chances of survival in anything beyond a vegetative state were already low. They soon sank to near nonexistent. For seven days I lay in a deep coma, my body unresponsive, my higher-order brain functions totally offline.

While the neurons of my cortex were stunned to complete inactivity by the bacteria that had attacked them, my brain-free consciousness journeyed to another, larger dimension of the universe: a dimension I’d never dreamed existed and which the old, pre-coma me would have been more than happy to explain was a simple impossibility.

I’m not the first person to have discovered evidence that consciousness exists beyond the body. Brief, wonderful glimpses of this realm are as old as human history. But as far as I know, no one before me has ever traveled to this dimension (a) while their cortex was completely shut down, and (b) while their body was under minute medical observation, as mine was for the full seven days of my coma.

Heaven Is Real: A Doctor’s Experience With the Afterlife.
Jag vet inte om jag tror på något ”efterliv” men detta var ändå en intressant berättelse.

Our perception, directly controls the activity of our genes.

Dr. Bruce H. Lipton, trained as a cell biologist and now bridging science and spirit, talks… in his thought-provoking and ground-breaking book The Biology of Belief …of two new biomedical research fields:

1. Signal transduction science, which “…recognizes that the fate and behavior of an organism is directly linked to its perception of the environment. In simple terms, the character of our life is based upon how we perceive it.”
2. Epigenetics, which “…is the science of how environmental signals select, modify, and regulate gene activity. This new awareness reveals that our genes are constantly being remodeled in response to life experiences.”

Dr. Lipton has demonstrated in his own research that the nucleus (where DNA is) of a cell can be removed and the cell can still function for a time…until it needs to repair itself…and then it breaks down and dies. He theorizes that the real “brain” of the cell is in the membrane, which interacts with the environment (this is the signal transduction mentioned above). He concludes that “the cell’s operations are primarily molded by its interaction with the environment, not its genetic code.”

Based on this New Biology, Dr. Lipton suggests that we need to move beyond Darwinian theory…which focuses on the importance of individuals (or an individual cell’s DNA)…to one that stresses the importance of the community (or the connection and reference of the individual cell to its environment).

Growth requires an open exchange between the organism and its environment; protection requires that the organism close down and wall itself off. War, violence, depletion of environmental resources, close-mindedness, ideological control (by religions and governments), prejudice, illness, depression, and fear are all examples of what happens to individuals and larger organisms (like countries) that go into protective mode and close down.

What’s the take away from Dr. Lipton of this New Biology? That we must change our competitive, dog-eat-dog, one-up-manship, survival of the fittest paradigm to one that supports everyone and everything on this planet…a paradigm of interconnection, openness, growth, and survival of the most loving.
