Assessing explicit processes does not influence the magnitude of implicit processes.

Area of Science:

• Cognitive Neuroscience
• Motor Control
• Human Adaptation

Background:

• Visuomotor adaptation involves both implicit (unconscious) and explicit (strategic) processes.
• Existing methods like the Process Dissociation Procedure (PDP) and Verbal Report Framework (VRF) assess both contributions concurrently.

Purpose of the Study:

• To investigate if assessing explicit visuomotor adaptation influences the observed magnitude of implicit visuomotor adaptation.
• To determine the impact of simultaneous assessment on implicit adaptation measurements.

Main Methods:

• Four participant groups underwent visuomotor rotation training.
• Two groups (PDP-IE, VRF-IE) had both implicit and explicit adaptation assessed.
• Two groups (PDP-I, VRF-I) had only implicit adaptation assessed.

Main Results:

• The magnitude of implicit visuomotor adaptation was comparable across all groups.
• Simultaneous assessment of explicit adaptation did not significantly alter implicit adaptation levels.

Conclusions:

• Assessing explicit visuomotor adaptation concurrently with implicit adaptation does not affect the measurement of implicit adaptation.
• The findings validate the reliability of PDP and VRF methods for measuring implicit visuomotor adaptation independently.
