A bit about Daniel Freudenthal

I’m a psychologist with an interest in the simulation of cognitive processes, in particular language acquisition. The main focus of my work is on MOSAIC, a computational model that is used to investigate how children’s early multi-word speech is shaped by the statistical properties of the language they hear. Simulations with MOSAIC have revolved around children’s increasing ability to correctly inflect verbs. Across a range of languages, MOSAIC produces the same types of errors at rates comparable to those in children because it is sensitive to the distributional statistics of the input to which it is exposed in a manner that places great weight on the last items in the speech stream (i.e. has an utterance-final bias, or strong recency effect).

My Role in LuCiD

Within LuCID, I am involved in two strands of research, both of which focus on the German language. The first involves learning the categories of words (e.g. verb or noun) on the basis of the lexical contexts (preceding and following words) in which they occur. A specific focus in this project is to investigate how processing biases and developmental variation affect the categorization process.

The second strand of research involves investigating ways in which MOSAIC can be extended to account for atypical language development. Children with Specific Language Impairment (SLI) are slow to acquire language and, depending on the language, have difficulty with verb inflection. This project examines how details of the inflectional paradigm pose differential challenges for learners of different languages.
