This article explores the affective impact of remote touch when used in conjunction with video telecon. Committed couples were recruited to engage in semi-structured discussions after they watched a video clip that contained emotionally charged moments. They used paired touch input and output devices to send upper-arm squeezes to each other in real-time. Users were not told how to use the devices and were free to define the purpose of their use. We examined how remote touch was used and its impact on skin conductance and affective response. We observed 65 different touch intents, which were classified into broader categories. We employed a series of analyses within a framework of behavioral and experiential timescales. Our findings revealed that remote touches created a change in the overall psychological affective experience and skin conductance response. Only remote touches that were judged to be affective elicited significant changes in EDA measurements. Our study demonstrates the affective power of remote touch in video telecommunication, and that off-the-shelf wearable EDA sensing devices can detect such affective impacts. Our findings pave the way for new species of technologies with real-time feedback support for a range of communicative and special needs such as isolation, stress, and anxiety.

The neurophysiological properties of rapid eye movement sleep (REMS) are believed to tune down stressor-related emotional responses. While prior experimental findings are controversial, evidence suggests that affective habituation is hindered if REMS is fragmented. To elucidate the topic, we evoked self-conscious negative affect in the participants (N = 32) by exposing them to their own out-of-tune singing in the evening. Affective response to the stressor was measured with skin conductance response and subjectively reported embarrassment. To address possible inter-individual variance toward the stressor, we measured the shame-proneness of participants with an established questionnaire. The stressor was paired with a sound cue to pilot a targeted memory reactivation (TMR) protocol during the subsequent night's sleep. The sample was divided into three conditions: control (no TMR), TMR during slow-wave sleep, and TMR during REMS. We found that pre- to post-sleep change in affective response was not influenced by TMR. However, REMS percentage was associated negatively with overnight skin conductance response habituation, especially in those individuals whose REMS was fragmented. Moreover, shame-proneness interacted with REM fragmentation such that the higher the shame-proneness, the more the affective habituation was dependent on non-fragmented REMS. In summary, the potential of REMS in affective processing may depend on the quality of REMS as well as on individual vulnerability toward the stressor type.

SynopsisIt has recently been suggested that the bilateral asymmetry of electrodermal activity (EDA) reported in schizophrenia may be related to unilateral temporal lobe dysfunction. To test this hypothesis, 3 aspects of EDA – skin conductance level (SCL), number of spontaneous fluctuations (SF), and skin conductance response (SCR) – were measured bilaterally in 10 patients who had undergone unilateral temporal lobectomy. No differences could be detected between the operated and non-operated sides within the patient group, nor between the patient and control groups. The implications of these findings are discussed.

Research examining whether negative affect leads to drinking has produced mixed results (Greeley and Oei, 1999; Sher and Grekin, 2007). The current project enlisted participants (n=43) oversampled for affective instability, arguably making them at higher risk for negative affect-driven alcohol consumption. The goals of this study were to 1) validate an ambulatory device for measuring electrodermal activity (EDA) and to 2) examine the relations between emotion, EDA, and alcohol use in real-time. Multiple self-reports of emotion, alcohol use, and behavior were obtained from participants each day over the course of one week using electronic diaries. EDA was assessed continuously during waking hours. The results suggested that ambulatory measurement of EDA is feasible, and agreement between ambulatory measures and traditional laboratory measures was moderate to high for number of skin conductance responses per minute. Skin conductance level was less consistent across measures. With regard to ambulatory findings, high negative affect and high arousal states during the day were generally related to decreased likelihood of same-day drinking and decreased estimated blood alcohol concentration, while positive affect was related to increased likelihood of drinking. Hostility and number of skin conductance responses interacted, such that low hostility and low arousal was related to greater amounts of alcohol consumed. In sum, negative affect and arousal were related to alcohol use in real-time, but effects were small and both were generally protective against alcohol consumption at the day-level. This study helps to clarify the role of arousal in affect-related drinking, while also adding to accumulating evidence that suggests negative affect-related drinking may not be an immediate coping response. Positive-affect drinking may be most relevant in early stages of alcohol use, even in an emotionally dysregulated sample.

SYNOPSISElectrodermal, electroencephalographic and perceptual measures of lateral hemispheric function were obtained from groups of chronic schizophrenics, depressives and normals on 2 occasions, separated by 4 weeks. The measures of hemispheric function were derived from previous research. About half of the schizophrenics were medicated on both occasions; the other schizophrenics underwent drug ‘washout’ before the first session. Results revealed that the measures of laterality were not strongly intercorrelated. In the perceptual task, the schizophrenics and normals displayed different laterality effects. Unlike the normals, the schizophrenics' left hemisphere function appeared to be inferior to the right hemisphere function in the perceptual task. The laterality effects of the depressives and normals differed on two electrodermal measures: skin conductance level and skin conductance response amplitude. The depressives' electrodermal activity from the right hand was diminished as compared with the left hand; the normals did not show this effect. Medication decreased electrodermal activity in the schizophrenics, but had no significant effect on laterality. These results suggest that the various measures of laterality used singly in previous research in psychopathology may not all assess the same phenomenon.

Preliminary Study

A reduced electrodermal activity (EDA) may be related to autonomic neuropathy (AN). The aims of this study were to independently study the characteristics of the EDA and its correlation with diabetes and AN. During a selfdesigned test, mean skin conductance level (MSCL), mean skin conductance response (MSCR) to stimuli, and difference in MSCL between feet (DBF) were obtained through a modelbased decomposition based on Bayesian statistics and mathematical convex optimization. A group of 22 subjects were included for the final test. Diabetic patients were stratified based on their clinical history and care habits, dividing them into those out of risk and those at risk of developing AN. Statistical difference was found for the latter regarding MSCR (p < 0,01) and DBF (p < 0,05) with respect to the control group. While past research failed to address potential sources of interference with the EDA measurement, namely emotional state, degree of concentration on the task, and body posture, this study proposes a welldefined protocol to stimulate subjects and acquire proper and reliable EDA data.

The subjectiveness of pain can lead to inaccurate prescribing of pain medication, which can exacerbate drug addiction and overdose. Given that pain is often experienced in patients’ homes, there is an urgent need for ambulatory devices that can quantify pain in real-time. We implemented three time- and frequency-domain electrodermal activity (EDA) indices in our smartphone application that collects EDA signals using a wrist-worn device. We then evaluated our computational algorithms using thermal grill data from ten subjects. The thermal grill delivered a level of pain that was calibrated for each subject to be 8 out of 10 on a visual analog scale (VAS). Furthermore, we simulated the real-time processing of the smartphone application using a dataset pre-collected from another group of fifteen subjects who underwent pain stimulation using electrical pulses, which elicited a VAS pain score level 7 out of 10. All EDA features showed significant difference between painless and pain segments, termed for the 5-s segments before and after each pain stimulus. Random forest showed the highest accuracy in detecting pain, 81.5%, with 78.9% sensitivity and 84.2% specificity with leave-one-subject-out cross-validation approach. Our results show the potential of a smartphone application to provide near real-time objective pain detection.
