Individual habituation response as defined in Equation 2 versus the reported PCL-M score. A negative value on the x-axis means that the participant tends to have overall sensitization (i.e., negative habituation) to stress-inducing events during the scenario, whereas a positive value indicates a tendency to habituation to stress-inducing events. The orange line represents the linear regression of the scattered points in blue. These findings indicate that participants with low PCL-M scores tend to be more sensitive to stress stimulation. A participant was considered to have a PTSD when the PCL-M score was greater than 36.
