William E. Merriman
Research Area: Experimental - Developmental
Research InterestsMy research focuses on children’s language, memory, and thought, with an emphasis on word learning and metacognition in early childhood. Some current lines of research concern:
- Awareness of Gaps in Linguistic Knowledge -- What procedure does a young child use to decide that some word is unknown, that some object cannot be named, or that some utterance cannot be interpreted clearly? How is the accuracy of these decisions related to the efficiency of various cognitive processes?
- Overconfidence in Memory – Why do young children make such unrealistically optimistic predictions about their memory performance? Why do they become less optimistic as they get older?
- Word Learning– How do children infer the category that a word denotes from observations of how the word is used (and not used).
Courses Frequently Taught
- Quantitative Methods in Psychology I (undergraduate)
