Figure 1
The first part of a logical tree illustrating how multiple hypotheses can be sequentially explored in order to zero in on the most important questions.
Figure 2
Logical tree illustrating the exclusion of the hypothesis that simulations are strictly necessary for conceptual processing.
Figure 3
Logical tree illustrating alternative hypotheses compatible with the pattern that acquired sensory-motor deficits often but not always lead to corresponding conceptual deficits.
Figure 4
Third part of the logical tree specifying more detailed questions on the role of simulations.
