Background data and autobiographical memory: Effects of item types and task characteristics

Background data, or life history measures, ask people to recall and report prior behavior and experiences. Although these measures have been found fro be effective predictors of performance, little is known about the characteristics of items contributing to accurate reporting and good recall. Accordingly, 153 undergraduates were asked to work on a complex, computer-based 'in-basket' task. In working through this task, objective indices of their activities were obtained. After completing this task, subjects were asked to answer a set of background data items describing their behavior and experiences during task performance. Additionally, they were asked to return one week later and, again, answer the background data questions. Indices of accuracy and recall consistency were obtained for various item types. In accordance with the literature of autobiographical memory, it was found that people could consistency recall and accurately report general summaries of activities and their reactions to the task. More specific actions or behaviors that were not linked to goals were not accurately and consistently recalled. The implications of these findings for the development and application of background data measures are discussed.
