During the lengthy and complex process of human evolution our ancestors had to adapt to extremely testing situations in which survival depended on making rapid choices that subjected muscles and the body as a whole to extreme tension. In order to seize a prey traveling at speeds that could reach 36 km per hour Homo sapiens had just thousandths of a second in which to anticipate the right moment and position himself before the prey arrived. He also had to prepare (...) the appropriate gesture, tensing his muscles and overcoming the resistance determined by body weight. While we are no longer faced with an environment that is anything so threatening, our brain continues to use these mechanisms day in day out to save time and energy, enabling us to avoid situations of danger, sense in advance the intentions of an interlocutor, and more besides. In this article we set out to show that our brain is not only a reactive mechanism, capable of reacting quickly to the stimuli that arrive from the external environment, but is above all a pro-active mechanism that allows us to make hypotheses, anticipate the consequences of actions, and formulate expectations: in short, to wrong foot an adversary.

The existence of an unaware psychic space that influences the way we think, perceive, and decide has been known for over a century. This space, defined by Freud as the “unconscious,” contains in it...

This article argues the necessity of overcoming the hierarchical and pyramidal conception of the central nervous system that has subordinated the motor function to the higher brain activities for at least the last 150 years. The evolution of some motor modes of behavior?such as the ability to construct and manipulate instruments?has given rise to an ?embodied logic? underpinning not only the development of models of action and prediction but also the production of gestures and sequences of syllables that are at (...) the basis of human communication. Whether it is a matter of shaking someone's hand, writing a letter, or whatever, each executive function?controlled by a series of nervous structures and mental procedures that process the information?requires behaviors that are oriented to a specific end.

From the seventies onward a large quantity of theoretical and empirical studies have investigated the heuristic principles and cognitive strategies that individuals use to deal with risky and uncertain situations. This research has shown how the explicative and predictive shortcomings of normative risk analysis depend in many respects on undervaluing the continuous interaction between the individual and the environment. There are factors that, day by day, represent significant obstacles to decision making.
