Otitis, Multiple Cue Probability Learning, and Control Theory

Claudia Gonzalez Vallejo
Athens, OH

My Brunswikian research:

1) I have followed up on work on otitis media that started in Albany, NY, when I worked with Tom Stewart. In collaboration with him, Junseop Shim, Paul Sorum, Gérard Chasseigne, Maria-Teresa Sastre, and Etienne Mullet, we recently rounded up a study that looked at diagnosis and treatment decisions of physicians in the U.S. and France, plus the responses of parents. Main results showed that both sets of physicians relied heavily on examination cues to make their judgments. Physicians within groups disagreed, but in comparison to each other, both French and U.S. doctors appeared to use similar strategies. There was also a lot of similarity between parents and physicians in terms of diagnosis and treatment judgments, even though the groups held different attitudes. In addition, some further analyses of these data that I performed show that the treatment decisions are not solely based on the information used to make the diagnoses, but that additional variables influenced treatments.

2) The other project is one that is still in the conception stage and deals with using control theory (Powers, 1978) to create a dynamic model of the person and the task in MCPL. This work is in collaboration with my colleague at Ohio University, Jeff Vancouver, who has recently programmed a tentative simulation model, which relies heavily on the notion that the human cognitive system, like the physiological system, tries to maintain equilibrium via negative feedback loops. My next task is to get data sets, and here is where you all can help me and guide me where to find the data, in order to test the dynamic predictions that the current version of the model(s) make (we can rather talk of a family of models)
