Reactions to daily events as a function of familiarity with an environment

Undergraduate participants provided measures of their psychological well‐being and described the positive and negative events that occurred each day, once during the first and second semesters of an academic year. For four of the five measures of daily well‐being, reactivity to negative events decreased from the first to second semester, whereas for four of the five measures of well‐being, reactivity to positive events did not change over the year. These results suggest that familiarity with an environment moderates reactivity to negative daily events. As people become more familiar with an environment, negative events may elicit smaller decreases in well‐being. In contrast, increases in well‐being elicited by positive events appear to be unrelated to familiarity with the environment. More broadly, these differences suggest that the reactivity to positive and negative events reflect the operation of different processes. Copyright © 2007 John Wiley & Sons, Ltd.
