On the localization of reward effects in overlapping dual tasks.

In dual-task (DT) situations, performance deteriorates compared with single-task situations. Such performance decrements are frequently explained with the serial scheduling of the response selection stages constituting a bottleneck. Proof of this assumption stems from the observation that response times for the second task (task 2; RT 2) increase with decreasing stimulus-onset asynchrony (SOA).

Comparing laboratory and online settings: equivalence in training and transfer effects for training task-order coordination processes.

Introduction: The literature on dual-task training suggests reductions in task-coordination costs with extensive practice, yet such regimens are resource-intensive. This study investigates the feasibility of online assessments for cognitive training studies by comparing training and transfer effects on task- coordination (TOC) skills in laboratory versus online settings.

Methods: We conducted a 5-day training regimen including pre-and post-test.
