Implication of explicit knowledge and subjective evaluation in procedural perceptual-motor learning.

Area of Science:

• Neuroscience
• Motor Control
• Cognitive Psychology

Background:

• Procedural Perceptual-Motor Learning (PPML) is crucial for acquiring new motor skills and diverse human behaviors.
• Inter-individual differences in PPML are increasingly attributed to learner-specific factors beyond task characteristics.
• Understanding these individual factors is key to optimizing motor learning strategies.

Purpose of the Study:

• To investigate the influence of explicit task knowledge and subjective evaluations on PPML.
• To explore how learners' strategies and mindsets impact performance in motor learning tasks.
• To differentiate the effects of explicit knowledge and subjective feedback across distinct PPML tasks.

Main Methods:

• Two experiments were conducted involving Serial Reaction Time Task (SRTT) for motor sequence learning and Target Jumping Task (TJT) for visuomotor adaptation.
• Participants completed post-learning questionnaires assessing explicit knowledge of task rules and subjective evaluations (stress, tiredness, motivation, attention, progress).

Main Results:

• In Experiment 1 (SRTT), explicit knowledge correlated with higher learning scores, perceived stress, and progress.
• In Experiment 2 (TJT), explicit knowledge correlated with lower learning scores, alongside perceived stress, tiredness, concentration, and progress.
• Subjective evaluations consistently moderated the relationship between explicit knowledge and PPML outcomes.

Conclusions:

• The study provides novel insights into inter-individual differences in PPML by examining explicit knowledge and subjective evaluations.
• Findings suggest that the impact of explicit knowledge on PPML is task-dependent and moderated by subjective learner experiences.
• Future PPML research should incorporate subjective reports to better understand learner-task interactions and individual differences.
