Asymmetrical effects of control on the expression of implicit sequence learning

Area of Science:

• Cognitive Psychology
• Neuroscience

Background:

• Implicit learning is often considered inflexible and context-dependent.
• However, transfer of implicit learning can occur under specific conditions.

Purpose of the Study:

• To test if increased control demands in a transfer task hinder implicit learning.
• To investigate the role of cognitive control in implicit sequence learning transfer.

Main Methods:

• Participants completed a serial reaction time task for training.
• Transfer tasks varied in control demands (lower, symmetrical, higher) compared to training.
• Implicit sequence learning was assessed by comparing performance on sequence vs. random trials.

Main Results:

• Implicit sequence learning transferred to conditions with symmetrical control demands.
• Transfer was hindered when transfer tasks required higher control demands than training.
• Lower control demands in transfer did not impair sequence learning expression.

Conclusions:

• The expression of implicit sequence learning is sensitive to the control demands of the orienting task.
• Cognitive control plays an indirect role in modulating implicit learning transfer.
• Implicit learning is not entirely inflexible and can be influenced by attentional and executive functions.
