We are interested in language enhancement and therapy: that is, both in enhancing language in healthy learners, especially those learning a second or additional language (Ullman, 2015, 2016; Ullman and Lovelett, 2016; Ozemir et al., in preparation), and in therapeutic approaches for improving language learning or relearning in individuals with disorders (Ullman, 2004; Ullman and Pullman, 2015).
Our predictions derive primarily from the declarative/procedural model. Strengthening learning, retention, knowledge, and use of information in declarative and procedural memory is quite well studied in humans and non-human animals, with a variety of behavioral, pharmacological and other approaches having been found to have positive outcomes. These interventions are thus predicted to also improve language, given its dependence on the two memory systems. Our work focuses on behavioral techniques (Ullman and Lovelett, 2016; Ozemir et al., in preparation), though we are also interested in pharmacological and other approaches.
We are also interested in the enhancement of other aspects of cognition. In a series of studies in Lombok, Indonesia, a large number of pregnant women were given either multiple micronutrients or only iron and folate. Multiple micronutrient supplementation led to improved cognition in the pregnant women themselves (Prado et al., PLoS ONE, 2012) and in their children, both at ages 3 to 4 (Prado et al.,Pediatrics, 2012), and still even at ages 9 to 12 (Prado et al., 2017). In general, the strongest effects were found for undernourished or anemic mothers. Socio-economic factors also played important roles in improving cognition.
