Description

A modified serial reaction time task in which a fixed 12-location stimulus sequence is randomly divided and assigned to each co-actor for response. The experiment comprised eight blocks: Blocks 1 to 6 and 8 were "constructed from a fixed sequence of locations, while the seventh block was constructed from an interference sequence". Dyads were assigned to a joint context (both respond to pre-assigned colours) or a baseline context (actor plus passive observer), with concurrent dual-EEG recording at 512 Hz. All behaviour and EEG data, and in-house scripts, are deposited on the Open Science Framework.

Design Implications

Context

Requirements

• Dual-EEG recording system with synchronized amplifiers
• Paired participants randomly assigned to joint or baseline context

Constraints

• Interference and main sequence assignment counterbalanced across dyads; only female participants recruited

Target Learners

• undergraduate students in dyads

Learning Goals

• implicit statistical learning of fixed stimulus sequences in joint and individual contexts

Claims

• A joint context with an active co-actor produces a steeper reaction-time learning slope than a baseline context with a passive observer in a complementary statistical learning task [+M]
• Theta-band brain-to-brain coupling increased more steeply during learning in the joint context and was modulated by the presence or absence of statistical regularity [+M]
• Inserting an interference sequence disrupted and then recovered joint-context performance: RT rose from Block 6 to 7 and fell from Block 7 to 8 only in the joint context [+M]
