Perceptual Retraining to Reduce Suicide Risk

"Perceptual retraining involves the systematic presentation of diluted malodors (i.e., odors perceived as threatening). For each individual, vials on either side of a pre-determined and ideographic detection threshold will be presented. During the retraining, participants will be given feedback to shift their bias away from the malodorous target stimuli. For example, in the context of diluted solutions participants will be given the feedback that they are correct when a neutral response is given to solutions that are above the starting threshold (stronger malodor) and incorrect when a target is endorsed that is below the starting threshold (weaker malodor)."
