A non-verbal process dissociation procedure to disentangle explicit from implicit sequence learning

Area of Science:

• Cognitive Psychology
• Neuroscience
• Learning Sciences

Background:

• Implicit and explicit learning are crucial cognitive processes.
• Existing methods often rely on verbal instructions, limiting research scope.
• Disentangling implicit from explicit learning requires non-verbal assessment tools.

Purpose of the Study:

• To validate a non-verbal adaptation of the Process Dissociation Procedure (PDP).
• To assess implicit and explicit sequence knowledge without verbal instructions.
• To investigate the role of awareness in sequence reproduction control.

Main Methods:

• A non-verbal version of the PDP was developed, removing explicit instructions.
• Participants learned spatial regularities through trial and error.
• Performance was assessed by contrasting inclusion and exclusion conditions, followed by a verbal report.

Main Results:

• High performance in sequence reproduction correlated with verbal awareness of task rules and sequences.
• Participants lacking awareness performed at chance level.
• Awareness was demonstrated as necessary for explicit control over sequence reproduction.

Conclusions:

• The non-verbal PDP effectively distinguishes between implicit and explicit learning.
• Awareness is a critical factor for explicit sequence learning and control.
• This method offers a valuable tool for studying learning in non-verbal populations.
