What is a 'nudge'? The concept is a relatively subtle policy shift that encourages people to make decisions that are in their broad self-interest. Nudge theory is a flexible and modern concept for: Understanding of how people think, make decisions, and behave, Helping people improve their thinking and decisions, Managing change of all sorts, and. Nudge is a concept in behavioral economics, political theory, and behavioral sciences which proposes positive reinforcement and indirect suggestions as ways to influence the behavior and decision making of groups or individuals. It can also happen with the visual perception: when we see something, multiple sensory information through different neural paths before reaching the higher cortical centers of the brain (the areas involved in memory, attention, in thought, consciousness and language).Īrrive more or less all at once, and are then integrated.īut if the brain processes them in two separate moments, the second stimulus may be so that the first is warned as a family, and therefore already lived.Nudge is a concept in behavioral economics, political theory, and behavioral sciences which proposes positive reinforcement and indirect suggestions as ways. This “passing leap” may cause the feeling of having already experienced a moment that really is new. In some cases, it may happen that the sensory information reaches directly to the “stock” of long-term memory, without going through the short-term (temporary storage that holds for a few seconds the brand new information, first time forming a memory solid or, on the contrary, forget). Other theories see in the déjà vu effect of a mismatch between neural pathways.įor example, it often happens that a fragrance evokes an experience of our lives.

Some epileptic patients report a feeling of déjà vu just before an attack.īecause epilepsy is characterized by disturbances in the electrical impulses that “turn on” the neurons, it is conceivable that the déjà vu is a temporary “technical problem” of the brain, in which the temporal neurons responsible for the sensation of familiarity light inappropriately making exchange the present with the past. Parts of the temporal lobes are also involved in the development of the feeling of familiarity, in recognition of known situations. Any hints on the neurological causes of this feeling comes from people with temporal lobe epilepsy, that portion of the cortex of each hemisphere of the brain that plays a key role in the retention of long-term memories.
