Researchers have detected that human behavior varies from time to time. An international team of researchers have identified some cognitive computations which say all about the human behavior. Specifically, how hastily we react to any event or future decision is very important. In a human body, reflexes and rapid responses are some of the most important behavioral attributes. If these attributes doesn’t exist in any human being then he won’t be able to perform even the necessary activities of life. For example, if a boxer doesn’t have a quick response to the situation then there are chances of him not able to defend the actions of his opponent, no matter what the action is, a block or an attack. A boxer only gets a fraction of seconds to anticipate his next attack. And talking about such rapid responses they are based on estimates of whether and when the events will occur. But now the question arises that how our brain is supposed to know when to or when not to pay attention. It is being stated by scientist and researchers that every kind of future event carries two distinct kind of uncertainty.
So the possibility of happening of an event is not certain. Until now, many researches published are based upon temporal prediction and has assumed that the possibility of whether an event will occur is a very stable effect. . However, this assumption has not been empirically proven. Furthermore, it is unknown how the human brain combines the probabilities of whether and when a future event will occur.
An international team of researchers from MPIEA and NYU has now investigated how these two different sources of uncertainty affect human anticipatory behavior. Using a simple but elegant experiment, they systematically manipulated the probabilities of whether and when sensory events will occur and analyzed human reaction time behavior. In their recent article in the journal Proceedings of the National Academy of Sciences (PNAS), the team reported two novel results. First, the probability of whether an event will occur has a highly dynamic effect on anticipation over time. Second, the brain's estimations of whether and when an event will occur take place independently.
