Handing a tool to someone can take more time than using it.

Area of Science:

• Cognitive Psychology
• Motor Control
• Action Planning

Background:

• Previous research suggested grasp-to-transport actions are initiated faster than grasp-to-use actions.
• This was interpreted as transport actions not requiring complex long-term memory activation.

Purpose of the Study:

• To investigate if grasp-to-use actions are initiated faster than grasp-to-transport actions when participants actively perform the task.
• To explore the role of long-term representations in both action types under different task constraints.

Main Methods:

• Experiment 1: Replicated previous findings using non-conventional "grasp-to-use" actions.
• Experiment 2: Participants actively performed both grasp-to-transport and grasp-to-use actions.

Main Results:

• Experiment 1 replicated prior results.
• Experiment 2 showed the opposite pattern: grasp-to-use actions were initiated faster than grasp-to-transport actions.
• This indicates that allocentric constraints can activate long-term representations for transport actions.

Conclusions:

• Long-term representations are necessary for both use and transport actions under specific conditions.
• Task demands and constraints significantly influence action planning and execution speed.
• The distinction between transport and use actions regarding activation of long-term representations is not absolute.
