Lecci studies the factors that influence decision making in different settings. He is currently researching decision making among jurors and decision making among patients as they interact with doctors. In these research projects we are typically interested in the interaction between some individual difference variable (such as degree of pretrial bias) and an experimental variable (such as the level of certainty in a verdict, as controlled through the manipulation of evidence). Other ongoing projects include the assessment of memory functioning, with an emphasis on early detection of memory problems like dementia (see Memory Assessment and Research Services), and the creation of algorithms to better estimate validity coefficients for dichotomous outcomes.
