Emergency services workers suppress their emotions in order to get the job done. If they ventilate afterwards they should process what's happened and then be fine. However, if the suppression is maintained the unprocessed memories get carried into future incidents where, despite their efforts, the old incidents can intrude. My in-person training teaches (e.g.) firefighters how to spot the signs of a 'suppressed' colleague, which I can sketch or show in video examples. Now I wish to develop an online-teaching format where I can show facial expressions in sufficient detail as to convince the student they are 'seeing' evidence of suppression (think '1000-yard' stare, being on the edge of tears, smiling but troubled). I envisage using a sequence of detailed faces being animated to go from neutral to sad to happy and other emotionally-charged states (e.g., shocked, confused).
A second task is for showing the layout of group debriefing sessions where up to 20 figures (eg. firefighters) are depicted sitting in a circle, taking it in turn to answer questions about the incident they have returned from. This is more procedural than emotional but an interplay of detailed faces with figures in a group would prove attractive.
