Description

The serial reaction time (SRT) task presents a deterministic 12-element sequence; the alternating serial reaction time (ASRT) task interleaves four predetermined elements with four random ones, creating an eight-element probabilistic sequence. Trial types (pattern, random-high, random-low) allow the article to state that the structure "allows the distinction between (i) general skill learning, measured by a decrease in RT for all trials, (ii) statistical learning, measured by the difference in RT between the random-high trials and the random-low trials ... and (iii) high-order deterministic learning, measured by the difference in RT between pattern trials and random-high trials."

Design Implications

Context

Requirements

• Blocks binned into five bins to compute online and offline gains; warm-up trials, repetition and trill triplets, and error trials discarded from analyses

Constraints

• In the SRT task with only deterministic transitions, general skill cannot be dissociated from sequence learning within each block or rest period; high-order rule learning was only observable in the long ASRT task

Target Learners

• healthy young adult participants in visuomotor sequence-learning experiments

Learning Goals

• implicit visuomotor sequence learning and its subcomponents

Claims

• Participants showed robust implicit statistical learning and general skill learning on the ASRT task in both studies [+W]
• Offline change in general skill between sessions 12 h apart was significant, but between sessions a week apart was not [+W]
• High-order rule learning in the long ASRT task increases during rest periods and decreases during practice [+W]
• General skill learning appears to occur during rest periods, but fatigue release cannot be excluded as an explanation [+W]
• Statistical learning in the ASRT task increases during practice periods and decreases during rest periods [+W]
