 As indicated in  Section 3.2,  the approach by Stapp contains elements of dual-aspect thinking as well, although this is not much emphasized by its author. The dual-aspect quantum approaches discussed in the present section tend to focus on the issue of a generalized mind-matter “entanglement” more than on state reduction. The primary purpose here is to understand correlations between mental and material domains rather than direct causally efficacious interactions between them.
