Learning-performance distinction and memory processes for motor skills: a focused review and perspective

Area of Science:

• Cognitive Psychology
• Motor Learning
• Neuroscience

Background:

• Behavioral research highlights a distinction between immediate performance during practice and long-term retention reflecting actual learning.
• Challenging practice conditions can hinder immediate performance but improve long-term motor skill retention, underscoring the learning-performance gap.

Purpose of the Study:

• To provide objective evidence for the learning-performance distinction in motor skills.
• To propose an empirically-based framework integrating motor memory processes with practice and retention timelines.
• To explore the neural mechanisms underlying motor performance and learning.

Main Methods:

• Review of motor learning studies comparing end-of-practice performance with delayed retention or transfer performance.
• Integration of behavioral evidence with understanding of motor memory processes (encoding, consolidation, retrieval).
• Incorporation of findings from noninvasive brain stimulation studies on motor memory processes and cortical regions.

Main Results:

• Delayed retention or transfer performance serves as a more reliable indicator of motor learning than performance at the end of practice.
• A proposed 'motor behavior-memory framework' integrates the temporal dynamics of memory processes with behavioral paradigms.
• Neuroscientific findings offer initial insights into the relationship between practice-induced performance changes and underlying motor memory mechanisms.

Conclusions:

• The learning-performance distinction is behaviorally supported, with delayed retention being a key measure of learning.
• The proposed framework provides a basis for understanding the interplay between motor memory processes and observable behavior.
• Future research utilizing this framework holds promise for advancing both theoretical understanding and practical applications in motor skill acquisition.
