Question

Quizplus · Accepted Answer

A longitudinal study follows the same group of individuals over an extended period of time, which is what Dr. Dawson is planning with his study on veterans. This will allow him to see changes in mental abilities and memory over time, and compare those with and without PTSD. An experimental study involves manipulating variables, which is not the case for this study. A cross-sectional study looks at different groups of individuals at one specific point in time, and chronological is not a type of study.
