Table 1.

The references and experimental details for the studies included in the CBMA are presented. Note that the Morey et al. and Hou et al. studies differed from the others with the stimulus modality being visual and the response involving a button press. We determined that this variance in task was acceptable as the subjects were still reacting to a traumatic stimulus relative to a neutral one.
