Eight years ago, four psychologists with varying backgrounds but a common in- terest in the impact of environmental stress on behavior and health met to plan a study of the effects of aircraft ise on children. The impetus for the study was an article in the Los Angeles Times about architectural interventions that were planned for several ise-impacted schools under the air corridor of Los Angeles Interna- tional Airport. These interventions created an opportunity to study the same chil- dren during ise exposure and then later after the exposure had been attenuated. The study was designed to test the generality of several ise effects that had been well established in laboratory experimental studies. It focused on three areas: the relationship between ise and personal control, ise and attention, and ise and cardiovascular response. Two years later, a second study, designed to replicate and extend findings from the first, was conducted.
