Fear and anxiety affect decision-making in the direction of more caution and risk aversion... Traumatized individuals pay more attention to cues of threat than other experiences, and they interpret ambiguous stimuli and situations as threatening (Eysenck, 1992), leading to more fear-driven decisions. In people with a dissociative disorder, certain parts are compelled to focus on the perception of danger. Living in trauma-time, these dissociative parts immediately perceive the present as being "just like" the past and "emergency" emotions such as fear, rage, or terror are immediately evoked, which compel impulsive decisions to engage in defensive behaviors (freeze, flight, fight, or collapse). When parts of you are triggered, more rational and grounded parts may be overwhelmed and unable to make effective decisions.
