A. Representations of Deceased Task: In this task three person blocks (deceased, living-control, demographic-control) were presented in a permuted order twice per run across four runs. Each block comprised three modalities (picture, story, think). For the picture modality two pictures were presented for 7.5 seconds each. For the story modality one story was presented in three lines with each line being presented for 5 seconds each. Stories alternated across blocks. In the think modality subjects were instructed to think about the deceased for 15 seconds. 500 millisecond fixations were presented in between each modality. Hence, each person block lasted 46.5 seconds. Within each block the ordering of modalities was randomized. Valence and arousal probes were presented following each block. To protect confidentiality, sample images for this figure are all taken from the FERET database of facial images collected under the FERET program, sponsored by the DOD Counterdrug Technology Development Program Office (37). B. Sustained Attention to Response Task (SART): The SART was presented following the representations of deceased task. During SART trials subjects were instructed to press a button every time a number aside from “3” was presented. Numbers were presented for 1.5 seconds with a fixation jitter of around 2 seconds. Blocks lasted for 25–35 seconds. Following each block subjects were probed regarding deceased and living-control related thinking. 16 SART blocks were performed per subject.
