Are Intentional Processes with Tool Use Similar for Simulated and Executed Actions?

Carl Gabbard and Priscila Caçola


We asked the question, does motor simulation (via imagery) and planning with execution have similar intentional characteristics? And, does use of a tool compared to arm reaching influence a different intention effect? We instructed participants to use motor imagery to estimate distance reachability with the hand (arm extended) and a 20-cm tool using a NOGO/GO intention paradigm. That is, use of imagery only and imagery with actual execution (IE). Results indicated no differences in accuracy within or between HAND and TOOL conditions. That is, there was no observable intentional effect. These findings lend preliminary support to an increasing body of evidence suggesting that the neurocognitive processes (in this case, intention) driving motor imagery and executed actions are similar for hand and tool use.
