My research investigates children's first language acquisition, mostly using judgment and production methodologies. I am particularly interested in children's errors involving question formation (e.g., *What he doesn't like?) and verb argument structure overgeneralization errors (e.g., *The joked giggled him; *I falled over), which I am currently investigating in an ERC-funded study of English, Hebrew, Hindi, Japanese and K'iche'. I also study children's acquisition of morphology, focusing particularly on Optional Infinitive errors in English and German (e.g., *He play), and tense/agreement/case-marking errors in morphologically rich languages, specifically Japanese, Polish, Finnish and Lithuanian.
I also have three sidelines: (1) Conducting studies that investigate alternative discourse/processing-based accounts of so-called "Universal Grammar" phenomena (e.g., subjacency; structure dependence), (2) Writing review articles/chapters (ideally controversial ones) and a textbook ("Child Language Acquisition: Contrasting Theoretical Approaches") and (3) Writing popular science, including my books Psy-Q, Are You Smarter than a Chimpanzee? , and my Observer/Guardian Personality Quiz Column; all of which introduces readers to interesting findings from the Psychology literature by means of interactive tests, games, illusions and quizzes.
