The Multiple Resource Theory and Model. Some Misconceptions in Data Interpretations.
DescriptionMany publications addressing multiple resource theory purport to provide evidence for or against the theory. Often such evidence is incomplete. Common flaws in experimental design and data interpretations are:
1. The multiple resource model, which proposes 4 dichotomies of resource separation within the brain is distinct from the theory, which is agnostic as to the identity of resources. It is easier to provide evidence against any particular dimension of the model, than to disprove the theory.
2. Experimental evidence against the model must show, in a dual task paradigm, that neither of the decrements in performance of either task from its single task counterpart is greater when common, rather than separate levels along one of the dichotomous dimensions is shared. Without data on decrements in both tasks, in both common and separate conditions, evidence cannot be provided.
3. Neither the model nor the theory predicts perfect time sharing when separate resources are used.
