modelling knowledge about causal relations

[Wolfgang Schoppek]

In my efforts of modelling the acquisition of causal knowledge I
encountered the following problem: Suppose there is an input-variable
affecting several output-variables. The goal is to create chunks which
represent these effects. For every successive state of the problem a new
chunk is created which holds the values of the variables. By comparing
the last two states the effects (of the input) can be induced.
And this is my question: can a production match information in any slot
of a lhs-chunk (performing an OR-operation like "if the value of output1
= 1 or the value of output2 = 1")?
Can anybody help me with that question, or has anybody
experience/problems in modelling the acquisition of causal knowledge in
ACT-R?
