Laboratory verbal-memory task design and results. In (a), examples are given of each portion of the task during one block of the laboratory verbal-memory paradigm. Categorical results are given in (b): Task performance is graphed separately for categories of posttraumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI). Dimensional results are given in (c): The scatterplots (with best-fitting regression lines) show the associations between symptom dimensions and task-performance measures (n = 147). Asterisks indicate significant differences between groups (*p < .05; **p < .01). CAPS = Clinician Administered PTSD Scale (Blake et al., 1995); RT = response time.
