Figure 4: Main study predictions (Hypotheses 1 and 2).

Figure 4:

This diagram shows the predicted MEP changes in FDI when the handle was either (a) visible (blocks a step/affords a reach) or (b) covered (blocks a reach/affords a step). Hypotheses 1 tested the prediction that simply viewing a handle without postural threat would result in a significant increase in MEP amplitude relative to a covered handle). Hypotheses 2 tested the prediction that this affordance effect (i.e. handle MEP greater than no-handle MEP) would be significantly increased in the context of postural threat.
