We present the leading hypotheses of a work in progress aiming at testing and comparing neural activities in the case of a cognitive illusion (the bat-and-ball illusion) and in the case of a typical instance of framing effects. We focus on contrasted answers linked to Stanovich's system 1 vs...

We suscribe to an account of framing-effects in decision theory in terms of an inference to a background informationa by the hearer when a speaker uses a certain frame while other equivalent frames were also available. This account was sketched by Craig McKenzie. We embed it in Bolker-Jeffrey...

Regrat helps to optimize decision-behaviour. It can be defined as a rational emotion. Several recent neurobiological studies have confirmed the interface between emotion and cognition at which regret is located and documented its role in decision behaviour. The data give credibility to the...

We investigate subjective reactions when subjects realize they have been victims of framing-effects in situations of risky choices - that is, when they violated the invariance principle in decision-theory. We try to assess various explanations of this violation in terms of bounded rationality...

We examined lay perceptions of the recent financial and economic crisis through 1707 questionnaires, administered via internet, to a varied group of volunteers in a range of countries: France, the US, Russia, Germany, Israel, and sub-Saharan Africa. Respondents graded the contribution of a large...

Neuroeconomics is a recent extension of behavioral economics which aims at uncovering the brain mechanisms and activities that mediate regular and anomalous behaviour. Gul and Pesendorfer (2005) have launched a critique against the neuroeconomic research program, based on what they argue is the...

Framing effects occur when different descriptions of the same decision problem give rise to divergent decisions. They can be seen as a violation of the decisiontheoretic version of the principle of extensionality (PE). The PE in logic means that two logically equivalent sentences can be...

Neuroeconomics is an emerging field crossing neuroscientific data, the use of brain-imaging tools, experimental and behavioral economics, and an attempt at a better understanding of the cognitive assumptions that underlie theoretical predictive economic models. In this paper the authors try two...
