dual tdcs enhances online motor skill learning and long Term Retention in chronic stroke patients
Frontiers in Human Neuroscience, 2013Co-Authors: Stephanie Lefebvre, Patrice Laloux, Andre Peeters, Philippe Desfontaines, Jacques Jamart, Yves VandermeerenAbstract:Background: Since motor learning is a key component for stroke recovery, enhancing motor skill learning is a crucial challenge for neurorehabilitation. Transcranial direct current stimulation (tDCS) is a promising approach for improving motor learning. The aim of this trial was to test the hypothesis that dual-tDCS applied bilaterally over the primary motor cortices (M1) improves online motor skill learning with the paretic hand and its long-Term Retention. Methods: Eighteen chronic stroke patients participated in a randomized, cross-over, placebo-controlled, double bind trial. During separate sessions, dual-tDCS or sham dual-tDCS was applied over 30 min while stroke patients learned a complex visuomotor skill with the paretic hand: using a computer mouse to move a pointer along a complex circuit as quickly and accurately as possible. A learning index involving the evolution of the speed/accuracy trade-off was calculated. Performance of the motor skill was measured at baseline, after intervention and 1 week later. Results: After sham dual-tDCS, eight patients showed performance worsening. In contrast, dual-tDCS enhanced the amount and speed of online motor skill learning compared to sham (p < 0.001) in all patients; this superiority was maintained throughout the hour following. The speed/accuracy trade-off was shifted more consistently after dual-tDCS (n = 10) than after sham (n = 3). More importantly, 1 week later, online enhancement under dual-tDCS had translated into superior long-Term Retention (+44%) compared to sham (+4%). The improvement generalized to a new untrained circuit and to digital dexterity. Conclusion: A single-session of dual-tDCS, applied while stroke patients trained with the paretic hand significantly enhanced online motor skill learning both quantitatively and qualitatively, leading to successful long-Term Retention and generalization. The combination of motor skill learning and dual-tDCS is promising for improving post-stroke neurorehabilitation.

The critical role of retrieval practice in long-Term Retention
Trends in Cognitive Sciences, 2011Co-Authors: Henry L. Roediger, Andrew C. ButlerAbstract:Learning is usually thought to occur during episodes of studying, whereas retrieval of information on testing simply serves to assess what was learned. We review research that contradicts this traditional view by demonstrating that retrieval practice is actually a powerful mnemonic enhancer, often producing large gains in long-Term Retention relative to repeated studying. Retrieval practice is often effective even without feedback (i.e. giving the correct answer), but feedback enhances the benefits of testing. In addition, retrieval practice promotes the acquisition of knowledge that can be flexibly retrieved and transferred to different contexts. The power of retrieval practice in consolidating memories has important implications for both the study of memory and its application to educational practice.

expectation of a final cumulative test enhances long Term Retention
Memory & Cognition, 2007Co-Authors: Karl K Szpunar, Kathleen B Mcdermott, Henry L. RoedigerAbstract:In the present study, subjects studied lists of words across four experimental conditions: whether (or not) subjects received initial testing for these lists and whether (or not) they were made aware of an upcoming final free-recall test. Initial testing enhanced final-test performance; however, subjects benefited more from initial testing when they also knew they would need to remember the information for a later test. The data suggest that holding an expectation of the final test encouraged the continued processing of study materials following an initial test, affecting the accessibility of these materials at the time of final recall. The results clearly illustrate how an expectation of a cumulative test might influence long-Term Retention, which may have important implications for educational practice.

Expanding retrieval practice promotes short-Term Retention, but equally spaced retrieval enhances long-Term Retention.
Journal of Experimental Psychology: Learning Memory and Cognition, 2007Co-Authors: Jeffrey D. Karpicke, Henry L. RoedigerAbstract:Expanding retrieval practice (T. K. Landauer & R. A. Bjork, 1978) is regarded as a superior technique for promoting long-Term Retention relative to equally spaced retrieval practice. In Experiments 1 and 2, the authors found that expanding retrieval practice of vocabulary word pairs produced short-Term benefits 10 min after learning, conceptually replicating Landauer and Bjork's results. However, equally spaced retrieval produced superior Retention 2 days later. This pattern occurred both with and without feedback after test trials. In Experiment 3, the 1st test occurred immediately or after a brief delay, and repeated tests were expanding or equally spaced. Delaying the first test improved long-Term Retention, regardless of how the repeated tests were spaced. The important factor for promoting long-Term Retention is delaying initial retrieval to make it more difficult, as is done in equally spaced retrieval but not in expanding retrieval. Expanding the interval between repeated tests had little effect on long-Term Retention in 3 experiments.

Repeated retrieval during learning is the key to long-Term Retention
Journal of Memory and Language, 2007Co-Authors: Jeffrey D. Karpicke, Henry L. RoedigerAbstract:Abstract Tests not only measure the contents of memory, they can also enhance learning and long-Term Retention. We report two experiments inspired by Tulving’s (1967) pioneering work on the effects of testing on multitrial free recall. Subjects learned lists of words across multiple study and test trials and took a final recall test 1 week after learning. In Experiment 1, repeated testing during learning enhanced Retention relative to repeated studying, although alternating study and test trials produced the best Retention. In Experiment 2, recalled items were dropped from further studying or further testing to investigate how different types of practice affect Retention. Repeated study of previously recalled items did not benefit Retention relative to dropping those items from further study. However, repeated recall of previously recalled items enhanced Retention by more than 100% relative to dropping those items from further testing. Repeated retrieval of information is the key to long-Term Retention.
