Quelques résultats théoriques et empiriques concernant ĺaccomodation informationelle (in French)

There are several experiences proving a linear relationship between information content of signs or events and reaction or perception time of the human operator (fig. l,2). As information is a function of probability there must be a convergence, called informational accomodation, of subjective to objective information if the (subjective) probability approaches the (objective) frequency. The speed of this process is correlated with intelligence, measured by success at school (average grades). The information of a sign or event multiplied by its frequency is called its striking value
A_i
. It is shown, that the estimations
s_i
of frequencies equal the relative striking values
a_i
, even beyond
h = 1/e \approx
37% if
Ss
are not too aged, intelligent or experienced in giving estimates (fig.3). Other experiences show the influence of the
a_i
even during the process of informational accommodation (fig.4,5).
