Scientists have confirmed the popular belief that without anything to guide them humans really do walk in circles.
It suggests we shouldn’t trust our senses when lost.
The research, originally commissioned by a popular science TV program in Germany, is published in the journal Current Biology.

One of the most prolific clichés in our culture is:
“Well, you know, if it sounds too good to be true, then it is!”
Yes, I know. I know why this precaution is so popular. I know why we let people get away with such a limiting pronouncement-over and over again! I know why we buy into such a dead end deal.
We’re scared. Or is it “scarred?”

An international research team has used lotto to show that the condition ‘spatial neglect’, which affects how we see the world, isn’t connected to how is it is imagined.
The findings to be published in the journal Cortex, suggest that the way we represent the world in our heads can operate independently of how it is actually perceived.

New research indicates that decreased cravings for pleasure may be at the root of a core symptom of major depressive disorder. The research is in contrast to the long-held notion that those suffering from depression lack the ability to enjoy rewards, rather than the desire to seek them.
Have you ever thought about the fact that there is never a moment when you are not thinking—that whatever happens in this world begins with a thought? Here are five simple steps to help you manage your thoughts and achieve success and happiness in life.

Shaking hands with yourself is an amusing out-of-body experience. The illusion of having your stomach slashed with a kitchen knife, not so much.
Both sensations, however, felt real to most participants in a Swedish science project exploring how people can be tricked into the false perception of owning another body.

These recent insights into memory are part of a larger about-face in neuroscience research. Until recently, long-term memories were thought to be physically etched into our brain, permanent and unchanging. Now it is becoming clear that memories are surprisingly vulnerable and highly dynamic. In the lab they can be flicked on or dimmed with a simple dose of drugs. “For a hundred years, people thought memory was wired into the brain,” Nader says. “Instead, we find it can be rewired—you can add false information to it, make it stronger, make it weaker, and possibly even make it disappear.” Nader and Brunet are not the only ones to make this observation. Other scientists probing different parts of the brain’s memory machinery are similarly finding that memory is inherently flexible.

How blind and deaf people approach a cognitive test regarded as a milestone in human development has provided clues to how we deduce what others are thinking.
“Hearing language is particularly important for understanding others, while other kinds of experience, such as the visual modality, are less important,” says Alison Gopnik, a cognitive psychologist at the University of California, Berkeley.

Time research has been a neglected topic in the cognitive neurosciences of the last decades: how do humans perceive time? How and where in the brain is time processed? This introductory paper provides an overview of the empirical and theoretical papers on the psychological and neural basis of time perception collected in this theme issue. Contributors from the fields of cognitive psychology, psychiatry, neurology and neuroanatomy tackle this complex question with a variety of techniques ranging from psychophysical and behavioural experiments to pharmacological interventions and functional neuroimaging. Several (and some new) models of how and where in the brain time is processed are presented in this unique collection of recent research that covers experienced time intervals from milliseconds to minutes. We hope this volume to be conducive in developing a better understanding of the sense of time as part of complex set of brain–body factors that include cognitive, emotional and body states.

No matter what you learn about stress, there remains one critical fact to keep in mind. Above all, stress is a disorder of perception.
It is not the actual degree of stress that determines its impact on health and well-being, but the perceived degree. What is stressful to one person may be ho-hum or even energizing to another.
There are obvious limits here, at least for most of us. Put someone in combat or in a persistently and intensely abusive situation, and the power of perception to create a positive spin substantially diminishes.
Nonetheless, there is evidence that, even in extreme circumstances, some folks fare far better than most. Their “secret” appears to be the capacity to mentally reframe what is happening around them into a less vile and more manageable scenario.

How is it that your mind is capable of handling new situations you’ve never previously encountered? How do you solve a problem you’ve never solved before? Is this just the magic of consciousness, or is there an underlying process — or algorithm — your mind uses behind the scenes to deal with the unique experiences you encounter each day? And if there is a process, how can you use it to improve your ability to think?

We live in an age where we are now exploring the mind and personal choice in society. Living in a society that produces technology that can read into the mind to determine what a person is thinking, and moving towards a future where even our desires might be determinable by machine. There is no doubt that these new discoveries that are coming to the forefront will bring about issues relating to mind control and manipulation of personal freedom. People are panicking at the thought of loosing the ability to choose their own goals and the things in which they wish to experience in life and also personal thoughts.
The true question to ask in this situation is, ‘is it ever possible to loose control of the mind?’
Our self perception determines our behavior – if we think we are inadequate, we act that way. If we think we are splendid, we act that way.
The pathway forward towards happiness and authenticity is not determined by something outside ourselves. It’s determined by our own thinking, our own inner process, our self perception.
So if our way forward feels blocked, it is blocked by the way we perceive ourselves, by our fears and how they cause us to act toward ourselves. We take forward with us our unhealed inner negative perceptions and recreate the same situations over and over.
Psychologists suspect that this space-time continuum may be more than a social convention, an artifice that we all simply agree to. Perhaps the brain has wired our perceptions of space and time together for some reason. A team of researchers has been exploring this question in the laboratory, using an unusual pair of spectacles.

Humans can see into the future, says a cognitive scientist.
It’s nothing like the alleged predictive powers of Nostradamus, but we do get a glimpse of events one-tenth of a second before they occur.
And the mechanism behind that can also explain why we are tricked by optical illusions.

Scientists studying US voters say our political views may be an integral part of our physiological makeup.
Their research, published in the journal Science, indicates that people who are sensitive to fear or threat are likely to support a right wing agenda.
Those who perceived less danger in a series of images and sounds were more inclined to support liberal policies.
The authors believe their findings may help to explain why voters’ minds are so hard to change.

Why is our first impulse to believe something that we see, read or hear? Especially if it is in print, online or comes in an “officially” looking packaging?
How do we teach ourselves and our students, that another impulse has to follow the first one immediately: Evaluate…critical thinking… learn to listen for and to your own “gut feeling”… cross referencing…
