Research Interests:
My research addresses a variety of questions concerning attention and working memory. Broadly speaking, attention and working memory comprise that part of the human information processing system that is concerned with current interactions with the environment. Thus, it includes aspects of perception and selection and memory and decision making as they relate to the current task and current state of awareness.
The typical model of selective attention has emphasized the physical characteristics of a stimulus that make it more likely to be attended, such as location and intensity. My work points out that the cognitive state of the perceiver (i.e., the perceiver's expectancy) is also important and that selection is the result of a match between what the perceiver expects and what is actually presented.
Although my interests are broad, my research follows a number of themes including:
- the role of semantic information in selective attention
- the role of awareness in attention and memory
- the relationship between attention and implicit memory
- individual differences in information processing
