Figure 1.
An example of a stimulus plate for each condition: left: VISUOSPATIAL+SEMANTIC (V+S); middle: VISUOSPATIAL (V), right: SEMANTIC (S). Subjects were asked to fill in the blank in the matrix with one of the three proposed choices. In the V+S condition, visuospatial manipulations are necessary for successful solving, but language mediation is available as a potentially facilitative strategy.
