are our brains bayesian assignment?

For the clearest evidence of Bayesian reasoning in the brain, we must look past the high‐level cognitive processes that govern how we think and assess evidence, and consider the unconscious processes that control perception and movement. ... “We really are Bayesian inference machines,” he says.

Each hemisphere of the brain is dominant for other behaviors. ... Of course, these are generalizations and in normal people, the two hemispheres work together, are connected, and share information through the corpus callosum.

Cognitive psychology is based on two assumptions: (1) Human cognition can at least in principle be fully revealed by the scientific method, that is, individual components of mental processes can be identified and understood, and (2) Internal mental processes can be described in terms of rules or algorithms in ...

The term “cognitive reserve” is thus meant to represent physiological robustness within functional brain networks, while the term “brain reserve” refers to differences in available structural neural substrates (Stern, 2002). See Figure 2 for a traditional threshold model of reserve.

Contrary to the 10 percent myth, scientists have proven that every part of the brain is integral for our daily functioning, thanks to brain imaging techniques like positron emission tomography and functional magnetic resonance imaging. Research has yet to find a brain area that is completely inactive.

For example, people can make a free choice as to whether to commit a crime or not (unless they are a child or they are insane). This does not mean that behavior is random, but we are free from the causal influences of past events. According to freewill a person is responsible for their own actions.

A Bayesian neural network (BNN) refers to extending standard networks with posterior inference. Standard NN training via optimization is (from a probabilistic perspective) equivalent to maximum likelihood estimation (MLE) for the weights. ... Using MLE ignores any uncertainty that we may have in the proper weight values.

Computer models of the syllogistic reasoning process are constructed. The models are used to determine the influence of three factors—the misinterpretation of the premises, the limited capacity of working memory, and the operation of the deductive strategy—on subjects' behavior.

Yes and no. You should be aware that your gut may not always be right but the more experiences you have and the more you learn, the more equipped your brain will be at giving you the correct gut feeling to guide your life and your decisions in the right direction.

Knowledge is accumulated from the outside in, and we can control how much and what kind enters our mind. Over time the database that is our mind is increasingly filled with information, the arbitrary “facts of life”. Knowing, on the other hand, like wind, cannot in any way be gathered, controlled or held.

Key assumptions of the biological approach: There is a direct correlation between brain activity and cognition. Biochemical imbalances can affect behaviour. Brain physiology can affect behaviour. Behaviour can be inherited (as it is determined by genetic information)

Metacognition: Ability to 'think about thinking' not limited to humans. Image: Wikipedia. Humans' closest animal relatives, chimpanzees, have the ability to "think about thinking" – what is called "metacognition," according to new research by scientists at Georgia State University and the University at Buffalo.

The relationship between brain and behavior seems to be the successor of the famous Cartesian mind-body dualism, where the brain is the physical or biological component and behavior the mental or psychological aspect. Despite its ancient origin, the body-mind dichotomy continues to be an unresolved problem nowadays.

Attention and focus in humans has been examined by brain scans. A study using neuroimaging of frequent Internet users showed twice as much activity in the prefrontal cortex of the brain compared to sporadic users. This is the part of the brain that is used for short-term memory and quick decision-making.

Heuristics are the "shortcuts" that humans use to reduce task complexity in judgment and choice, and biases are the resulting gaps between normative behavior and the heuristically determined behavior (Kahneman et al., 1982).
