Georgetown University Medical Center distributed a press release on a paper that was published in the journal Proceedings of the National Academy of Sciences. The research combines results from multiple studies involving a total of 665 participants. It shows that children learn their native language and adults learn additional languages in evolutionarily ancient brain circuits that also are used for tasks as diverse as remembering a shopping list and learning to drive - the same brain circuits that allow birds to remember where they hid their acorns and allow rats to perform grooming sequences. The findings have broad research, educational, and clinical implications.

Georgetown University Medical Center distributed a press release on a paper that was published in the journal Bilingualism: Language and Cognition. The study reports an experiment that found that early bilinguals (who had learned both English and Mandarin at an early age) showed brain advantages over (English speaking) monolinguals at learning an additional language in adulthood. Specifically, the bilinguals showed more native-like brain processing of the additional language than the monolinguals, both at early and later stages of learning the language.

We were awarded a grant from the Tourette Association of America: "Is procedural memory enhanced in Tourette syndrome?". The project, which follows up on our recent papers suggesting that procedural memory and grammar may be enhanced in children with Tourette syndrome, comprehensively investigates procedural memory, language (in grammar, across syntax, morphology, and phonology, and in lexical processing, as well as in grammar and word learning), declarative memory, working memory, and inhibitory control, in children with TS and typically developing control children. The Principal Investigator is Michael Ullman, with subcontracts to Phillip Hamrick (Kent State), Stewart Mostofsky (Kennedy Krieger Institute and Johns Hopkins), and Donald Gilbert (Cincinnati Children's Hospital).
Harvard University, Grand Challenges Canada, and other institutions distributed a press release on a paper that we published in Lancet Global Health. The paper reports that if women (in Lombok, Indonesia) took multiple micrountrients while pregnant, their children had better cognition (as compared to women who did not take these micronutrients) when they were about 10 years old. In fact, the children's procedural memory advantages were equivalent to the increase in score typical after an additional half-year of schooling. Additionally, we found that socio-economic factors such as a strong nurturing environment also significantly positively affected the children's cognition.

A grant from the Swedish Research Council was awarded to Mikael Heimann (PI; Linköping University, Sweden), Rachel Barr (co-PI; Georgetown University), and Michael Ullman (co-PI). The project, entitled "Which neurocognitive learning and memory systems are associated with language development in 9- to 22-month-old children?", examines the relationship between declarative and procedural memory on the one hand, and lexical and grammatical language abilities on the other, in a longitudinal study of infants.

Newcastle University in the UK distributed a press release on a paper that we published in the journal Brain and Language. First author Cristina Dye is at Newcastle. The paper reports that children with Tourette syndrome are faster at repeating made-up words than typically developing children. This is interpreted as reflecting speeded rule-governed combination of phonological segments, since non-word repetition depends importantly on (de)composition of these segments. The results are consistent with our previous findings suggesting speeded rule-governed combination in morphology (Walenski et al., 2007). We suggest that, more generally, rule-governed grammatical combination may be speeded in Tourette syndrome, perhaps due to its dependence on frontal/basal-ganglia circuits that also underlie tics, which share the characteristic of being fast and semi-voluntary.

Georgetown University Medical Center distributed a press release on a paper that was published in a special issue on reading and math in the journal Frontiers in Psychology. The paper proposes that developmental math disability can be explained in part by abnormalities of brain structures subserving the procedural memory system, which underlies our learning of automatized skills like driving or grammar. That is, the paper extends the procedural deficit hypothesis (PDH) from language-related disorders (specific language impairment, dyslexia) to math disability. This brain-based account of math disability is motivated in part by the presence of math problems in children with dyslexia or specific language impairment, suggesting that the deficits may share causal mechanisms. The account is also motivated by the fact that learning automatized math skills, which are impaired in math disability, likely depend on procedural memory. Although the paper does not claim that the PDH is likely to fully explain math disability, it suggests that the hypothesis could have substantial explanatory power, and may provide a useful theoretical framework to advance our understanding of the disorder.

An NIH R21 grant, HD087088 (2016-2018), “The neurocognition of procedural and declarative memory in dyslexia and S-RCD”, was awarded to Laurie Cutting from Vanderbilt University (Principal Investigator) and Michael Ullman (Subcontractual Principal Investigator). Using fMRI and behavioral approaches, the project examines the hypotheses that two neurodevelopmental reading disorders, dyslexia and specific-reading comprehension disorder (S-RCD), may be at least partly explained by impairments of procedural memory and declarative memory, respectively.

Natasha Janfaza, an undergraduate in the lab, was awarded a Kalorama Fellowship for the summer of 2015, from Georgetown University. The Kalorama Fellowship offers select Georgetown undergraduates an intensive summer research experience in the sciences or humanities to pursue an independent research project under the guidance of a mentor. She will be working with Michael Ullman on a study examining the relation between music learning, language learning, and memory systems.

Georgetown University Medical Center distributed a press release on the publication of a paper in the journal Neuroscience and Biobehavioral Reviews. The paper proposes that individuals with five neurodevelopmental disorders — autism spectrum disorder, obsessive-compulsive disorder, Tourette syndrome, dyslexia, and specific language impairment — compensate for a wide range of deficits by relying on a single powerful and nimble system in the brain known as declarative memory. This hypothesis, which may extend to other disorders (e.g., ADHD, aphasia, Parkinson's disease), has potentially important therapeutic, diagnostic, and basic research implications.

We were awarded a National Science Foundation grant: NSF BCS 1439290 (2014-2017), "Second language acquisition and long-term retention in a mini-language". The project examines how our brains change as we learn a second language. Adult participants learn a reduced version of the Basque language while both behavioral and neural (fMRI) measures are continuously acquired, from initial exposure to high proficiency, and then again weeks later to test retention. The project should reveal for the first time how the brain changes in real time as it learns a language.
Newcastle University distributed a press release on the publication of a study in the journal PLoS ONE. The study suggests that girls and boys may rely on different neurocognitive mechanisms for aspects of grammar: specifically, whereas boys appear to compose rule-governed complex forms from their parts (e.g., walk + -ed), girls are more likely to store and retrieve them as chunks (e.g., "walked").

Led by Jarrad Lum, we published a series of meta-analyses on procedural memory in various disorders. These suggest that procedural memory is impaired in dyslexia, Specific Language Impairment (SLI), and Parkinson's disease. The meta-analyses focused on the Serial Reaction Time (SRT) task, the most widely used task to probe procedural memory. A press release was also distributed for one of these papers.
