The investigations concerning the dynamics of behaviour settings imply an analysis of its apati-temporal dimension (Beaumont, 1982). Even though the coexistence of both attributes have been widely discussed (Bennet & Chorley, 1978); clearly, a possible alternative would be to consider the utilization of space along successive stages or points of time (Bennet, 1978) 50 that the necessary material -empirical data-was available for modelling behaviour in certain situations previously charactsrized;it would be later possible to carry out the appropiate theoretical previsions to which empirical results should adjust with the least white noise.
