Cambridge Journals Online – Abstract

Via Scoop.itBounded Rationality and Beyond
Complex and widespread activation in many brain areas is seen while performing, listening or mentally imaging music, activity that varies with training, previous exposure, personal preference, emotional involvement and many other factors. Playing a musical instrument demands extensive motor and cognitive abilities, and early musical learning results in plastic reorganization of the developing brain – one example being the increased cortical representation area for the left little finger in (right-handed) string-players, which correlates with age at the start of training. Even though the developing brain has the most pronounced changes, the adult healthy brain has a considerable plasticity. Conductors have superior spatial tuning compared with non-musicians and pianists. Attentive listening to music for as little as three hours can temporarily alter the auditory cortex. Interactions between genetic predisposition, environment and training play a role in music as in other areas. It has been proposed that musical training may improve other cognitive functions. There is some evidence that this may be the case but it is an area that needs further exploration.

EconPapers: Why Music? A look at Art as Propaganda

Via Scoop.itBounded Rationality and Beyond
By Elizabeth Whitcombe; Music can influence our emotions and the quality of our judgements. Our emotions play a key role in how we reason. If we are emotionally out-of-whack, then we will not be able to reason as effectively. Music is the art form that is most able to dissuade us from thinking critically. Our brains have a plastic property – the circuits we use more get stronger, those we use less atrophy. The characteristics of the music you listen to; and the way you choose to listen to it will affect your ability to make decisions. Because of these properties music has always been an attractive vehicle for propaganda. Music’s power to persuade is at the heart of Plato’s argument for censoring the Arts. So what gives music this power? Nature built us to look for beauty, and music exploits our tools for finding it.

EconPapers: Economics and psychology.Perfect rationality versus bounded rationality

Via Scoop.itBounded Rationality and Beyond
By Daniele Schilirò ; Abstract: Classical mathematical algorithms often fail to identify in time when the international financial crises occur although, as the classical theory of choice would suggest, the economic agents are rational and the markets are or should be efficient and behave also rationally. This contribution does not pretend to give a complete answer to these questions, but it will highlight some well-known limits of the classical theory of rational choice and compare this theory of choice with the approach that seeks to combine economics and psychology and that has established itself as cognitive or behavioral economics. In particular, the present paper will focus on the juxtaposition of the concepts of perfect rationality and bounded rationality. It concludes with some references to the literature of behavioral finance which has given important contributions in explaining the behavior and the anomalies of financial markets.

Via Scoop.itBounded Rationality and Beyond

Social neuroscience is a rapidly growing discipline that examines the relationship between the brain and social behavior. The “social brain hypothesis” posits that, over evolutionary time, living in large, social groups favored the physical growth of brain regions important for social behavior.
