a number of active brain areas in the healthy participants during game play, including activation of several large folds within the frontal lobe known to be involved in decision-making. In the smoking group, however, no hotspots of brain activity seemed tied to predictions made by the quantum model. As the model reflects participants' ability to learn from mistakes, the results may illustrate decision-making impairments in the smoking group, the authors noted.

However, if players aren't allowed to know the result of the first coin flip, they rarely make the second gamble.
When known, the first flip does not sway the choice that follows, but when unknown, it makes all the difference. This paradox does not fit within the framework of classical rei...
In their new study, Zhang and his colleagues pitted 2 quantum-based models of decision-making against 12classical psychology models to see which best predicted human behavior during a psychological task.The experiment, known as the
an individual's final choice is unknown and unpredictable. Quantum mechanics also acknowledges that people's beliefs about the outcome of a given decision — whether it will be good or bad — often reflect what their final choice ends up being. In this way, people's beliefs interact, or become "
"Cognitive scientists found that there are many 'irrational'human behaviors,"Xiaochu Zhang, a biophysicist and neuroscientist at the University of Science and Technology of China in Hefei, told that Classical theories of decision-making attempt to predict what choice a person will make given cert...
"One could say that the 'quantum-based' model of decision-making refers essentially to the use of quantum probability in the area of cognition," Emmanuel Haven and Andrei Khrennikov, co-authors of the textbook "Quantum Social Science" (Cambridge University Press, 2013),said.

Scientists can mathematically model this entangled state of superposition — in which two particles affect each other even if they’re separated by a large distance — as demonstrated in a 2007 report published by the Association for the Advancement of Artificial Intelligence .

"We hope that quantum reinforcement learning will also shed light on [these fields], providing unique insights."
In time, perhaps quantum mechanics will help explain pervasive flaws in human logic, as well as how that fallibility manifests at the level of individual neurons.
the behavior of a particle located in Japan would alter the behavior of its entangled partner in the United States. In psychology, a similar analogy can be drawn between beliefs and behaviors. "It is precisely this interaction," or state of entanglement, "which influences the measurement outcome...
Consider an example:
Imagine you're placing bets on whether a tossed coin will land on heads or tails. Heads gets you $200, tails costs you $100, and you can choose to toss the coin twice. When placed in this scenario, most people choose to take the bet twice regardless of whether the initi...
Some scientists think quantum mechanics can help explain human decision-making.
The same fundamental platform that allows Schrödinger's cat to be both alive and dead, and also means two particles can "speak to each other" even across a galaxy's distance, could help to explain perhaps the mo...
To bolster the value of their study, the team took brain scans of each participant as they completed the Iowa Gambling Task. In doing so, the authors attempted to peek at what was happening inside the brain as participants learned and adjusted their game-play strategy over time. Outputs generated...
Drawing from one deck may earn a player large sums of money in the short term, but it will cost them far more cash by the end of the game. Other decks deliver smaller sums of money in the short-term, but fewer penalties overall. Through game play, winners learn to mostly draw from the "slow and s...

Cognitive rigidity is present in many mental health disorders, including obsessive-compulsive disorder, major depression, and autism spectrum disorder.
Research shows that cognitive flexibility depends on the network of the frontal lobe and "striatal" brain regions.

Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.
This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!
Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.
Don’t look further if you love learning new things. A refreshing concept that provides quick ideas for busy thought leaders.
Brilliant. It feels fresh and encouraging. So many interesting pieces of information that are just enough to absorb and apply. So happy I found this.
Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.
Even five minutes a day will improve your thinking. I've come across new ideas and learnt to improve existing ways to become more motivated, confident and happier.
I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
