Analyzing response time distributions: Methodological and theoretical suggestions for prospective memory researchers

The analysis of response times from prospective memory experiments has resulted in multiple theoretical propositions about the role of attention in prospective memory. Extant theories of prospective memory are in good agreement that attention is necessary for detecting intention-related cues. However, these theories were primarily formulated to describe differences in mean reaction times across experimental conditions. While this approach has been fruitful for establishing a fundamental relation between attention and prospective memory, reaction time modeling techniques can be applied to prospective memory data to better constrain theorizing. In the current work, the ex-Gaussian distribution is fit to data from a prospective memory task. The results from this analysis suggest that modeling reaction time data has the potential for clarifying our understanding of the role of attention in prospective memory.
