Van Petten's laboratory has two principal lines of research. In memory, their work is motivated by the fact that performance in real life memory tasks frequently requires more than raw memory ability, but also requires strategic or executive processes: deliberate search for information that does not come immediately to mind, decisions as to whether a memory is reliable enough to act on and resolution of interference between similar memories. Broadly, these executive processes have been associated with prefrontal cortex. Experiments using event-related potential (ERP) measures of human brain activity in healthy participants and those with brain damage are devoted to teasing apart the different brain processes that participate in episodic memory and understanding how they cooperate to yield successful performance (and how incorrect memory judgments arise from bottlenecks in different processes). They also work on the memory changes that occur in normal aging, and their relationship to anatomical changes in the brain. Language research investigates how smaller elements are combined to produce larger units with different meanings, with a current focus on two general sorts of problems: 1) how the meanings of individual words are modified by the overall context of a sentence, and how people select or build those contextually appropriate meanings, and 2) how listeners segment full words out of the speech stream, and avoid semantic processing of spurious units - like the "cap" in both "captain" and "handicap." In both domains of research, they attempt a thorough analysis of people's behavior, the brain activity that precedes or accompanies that behavior and how the two are related.
