This study was conducted to test the hypothesis that two films that induce a sad feeling would elicit different physiological responses depending on an additional context of the film contents related to either avoidance (disgust) or attachment (tenderness). Reactivity was evaluated for facial behavior, heart rate, pulse transit time, skin conductance, and subjective experience. Participants reported feeling less happy and showed increased facial activity related to the sad content of both films. The sad film related to avoidance induced an increase in skin conductance level and response rate. In contrast, the sad film related to attachment induced a decrease in amplitude of skin conductance responses and heart rate. The study showed that while the common sad content of both films disturbed mood or provoked negative feelings, additional affective contexts induced either a decrease or an increase in physiological arousal.

Emdr Therapy

Patients with posttraumatic stress disorder (PTSD) demonstrate abnormal psychophysiological responses to stressful events. Given that eye movement desensitization and reprocessing (EMDR) therapy appears to be a treatment of choice for trauma victims, the aim of the present study was to determine if psychophysiological responses to stress decreased after a single EMDR session. Six PTSD patients were treated by an EMDR therapist. Their psychophysiological responses (heart rate and skin conductance) were recorded before and after the EMDR session under two conditions: (a) in a relaxed state and (b) while visualizing their own traumatic event. At the end of the session, all patients had a significant reduction in their PTSD symptoms, which confirms previous results demonstrating the efficacy of the EMDR approach. Second, after only one EMDR session, heart rate and skin conductance during the trauma recall decreased significantly as compared to a relaxing state.

Concealed Information

The process of information concealment is more relevant than ever in this day and age. Using a modified concealed-information test (CIT), we aimed to unmask this process by investigating both the decision and the attempt to conceal information in 38 students. The attempt to conceal (vs. reveal) information induced a differential physiological response pattern within subjects—whereas skin conductance increased in both conditions, respiration and heart rate were suppressed only in the conceal condition—confirming the idea that these measures reflect different underlying mechanisms. The decision to conceal (vs. reveal) information induced enhanced anticipatory skin conductance responses. To our knowledge, this is the first study that observed such anticipatory responses in an information-concealment paradigm. Together, these findings imply that our physiological responses reflect, to some degree, both the decision and the attempt to conceal information. In addition to strengthening CIT theory, this knowledge sheds novel light on anticipatory responding in decision making.

Female Subjects

Verbal, heart rate, and skin conductance responses were measured while 20 male and 20 female subjects viewed antimale and antifemale sexual cartoons. The verbal ratings indicated that males preferred both types of cartoons more than females. However, no differences between heart rate and skin conductance measures were noted between the sexes. Skin conductance indicated that both sexes produced greater response to the antimale than the antifemale cartoons. Also, heart rates decelerated 5 sec. after presentation of the cartoons. Skin conductance seems to reflect a possible emotional reaction to the cartoons, whereas heart rates may reflect an information-processing component.

Low Exposure

SynopsisA sample of 77 women of high and low noise sensitivity in 1977, living in areas of high and low exposure to aircraft noise, were interviewed in the community in 1980. High, intermediate and low noise sensitive women were compared, using measures of blood pressure, heart rate, skin conductance, hearing threshold, uncomfortable loudness level and magnitude estimation of six tones. These physiological measures did not clearly distinguish different noise sensitivity groups, except that highly noise sensitive women had a consistently slower heart rate. Noise sensitivity was not related to auditory threshold. In the high aircraft noise area there were significantly more skin conductance responses than in the low aircraft noise area, irrespective of noise sensitivity. This may be the result of chronic exposure to high aircraft noise.

Comfort drives purchasing decisions for the equipment we interact with each day. Though manufacturers would like to claim to provide the most comfort over their competitors, a quantifiable metric based on physiological responses does not exist. The current research project examined the potential relationship of physiological measures with an individual's subjective level of comfort and discomfort. Heart rate variability and skin conductance responses were collected in a controlled laboratory environment along with a behavioral measure, the number of times the seated position was adjusted. During a 20 minute seated trial participants provided periodic responses to their subjective levels of comfort and discomfort. Discomfort was predicted through an interaction of the seat type (padded or rigid) and the number of adjustments made during a trial. Comfort had no significant predictors. Results showed no predictive power of heart rate variability or skin conductance responses. These results point toward use of measures of discomfort, rather than comfort, and observation of behaviors while seated.
