Expert Memory in Blindfold Chess960 - An Interpretation in the light of LIDA


Chessplayers expert’s perception is heavily theory laden as evidenced by the performance at recalling chess positions of an expert only allowed to glimpse the board for no more than 10 seconds. When the theoretical background is partially destroyed as in Chess 960, the recall under the same conditions is diminished from about 80% correct recalls to less than 60% (in our experiments). The view that "perception is cognition" seems to have a relation to the concept of sparse dictionaries in the software framework of learning intelligent distribution agent (LIDA). The particular experiments of this paper argue for the former concept and the probable existence of independent networks of activation of memory such as Damasio’s zones of convergence-divergence, also compatible with the LIDA concept. Such an interpretation leads not only to reaffirm Ericsson & Kintsch’s concept of Long Term Working Memory, but also the hypothesis of a unified theory of memory.
