1. "A mental structure that codes and stores external inputs, driving the search of the organisms for new inputs" (E. PESSA, 1992, p. 433).

E. PESSA quotes NEISSER who redefined the concept (1976). He explains that the Structure is influenced by the inputs "when they cannot be coded by using the existing categories and a schema modifications is required. On the other hand, we have a trend toward self-consistency, because the organism is searching only for the stimuli that are required by the schema itself" (Ibid).

This is the autopoietic aspect of the schema: it tends to organizational closure.

This schema concept also seems useful in organizations, which appearently react in the same fashion.

Schema construction is more or less equivalent to back propagation algorithm shaping.

2. "A symbolic structure that can be filled by a specific type of information" (E. BUCHBERGER, 1987, p. 51).

This is a more formal meaning, in no way contradictory to the formar one.
