Research Activity


My current research focus is on inference processes during reading comprehension, and the conditions which support the elaborative inferences that can be drawn. Background material on the issues and methods in this work can be found in the article by R. Till, E. Mross, and W. Kintsch, entitled "Time course of priming for associate and inference words in a discourse context," published in Memory and Cognition, 1988, 16, pages 283-298. The most recent presentation of this line of work was in the 2006 talk by R. Till and S. Normandin, entitled "Activation and persistence of thematic inferences in more and less skilled readers," given at the annual meeting of the Society for Text and Discourse.

In a related line of work, I have recently begun a project examining the effects of preoccupation (or "zoning out") on the comprehension of text materials. Thematic inferences are often missed when readers zone out, and even the detection of contradictory information may be impaired.

Several lines of my work on cognitive aging, including visual perception, short-term memory, picture memory, and language comprehension, have led me to a general interest in the study of adulthood and aging. This, in turn, prompted my work on a textbook, now in its third edition: R. Till and J. Lugo, Adulthood and Aging, 1998, published by CAT Publishers, Redding CA.

I am also interested in research on the assessment of student learning by psychology majors. For example, my recent WPA (2006) paper reported on capstone students' psychological knowledge as related to course work taken in psychology.

Students interested in working on research projects in these areas are encouraged to talk with me. They can earn some course credit (through PSY 485) for contributions to the research through involvement as part of a research team.
