Background: The search for autonomic correlates of emotional processing has been a matter of interest for the scientific community with the goal of identifying the physiological basis of emotion. Despite an extensive state-of-the-art exploring the correlates of emotion, there is no absolute consensus regarding how the body processes an affective state.Objectives: In this work, we aimed to aggregate the literature of psychophysiological studies in the context of emotional induction. Methods: For this purpose, we conducted a systematic review of the literature and a meta-analytic investigation, comparing different measures from the electrodermal, cardiovascular, respiratory and facial systems across emotional categories/dimensions. Two-hundred and ninety-one studies met the inclusion criteria and were quantitatively pooled in random-effects meta-analytic modelling. Results: Heart rate and skin conductance level were the most reported psychophysiological measures. Overall, there was a negligible differentiation between emotional categories with respect to the pooled estimates. Of note, considerable amount of between-studies’ heterogeneity was found in the meta-analytic aggregation. Self-reported ratings of emotional arousal were found to be associated with specific autonomic-nervous system (ANS) indices, particularly with the variation of the skin conductance level. Conclusions: Despite this clear association, there is still a considerable amount of unexplained variability that raises the need for more fine-grained analysis to be implemented in future research in this field.

BackgroundEye movement desensitisation and reprocessing (EMDR) is a relatively new therapeutic technique that has been proposed as a treatment for post-traumatic stress disorder and other anxiety complaints.MethodWe compared the efficacy of EMDR with that of exposure in viv. in the treatment of a specific phobia. Twenty-two spider-phobic children who met the DSM – III – R criteria for specific phobia participated in the study. Children were treated with one session of exposure in viv. and one session of EMDR in a crossover design. Treatment outcome was evaluated by self-report measures, a behavioural avoidance test and a physiological index (skin conductance level).ResultsResults showed positive effects of EMDR, but also suggest that it is especially self-report measures that are sensitive to EMDR. Improvement on a behavioural measure was less pronounced, and exposure in viv. was found to be superior in reducing avoidance behaviour. With regard to skin conductance level, EMDR and exposure in viv. did not differ.ConclusionsEMDR has no additional value in treatment of this type of animal phobia, for which exposure in viv. is the treatment of choice.

AbstractCooperation is pivotal for society to flourish and prosper. To ease cooperation, humans express and read emotions and intentions via explicit signals or subtle reflections of arousal visible in the face. Evidence is accumulating that humans synchronize these nonverbal expressions, as well as the physiological mechanisms underlying them, potentially promoting cooperative behavior. The current study is designed to verify the existence of this putative linkage between synchrony and cooperation. To that extent, 152 participants played multiple rounds of the Prisoner’s Dilemma game in a naturalistic dyadic interaction setting. During one round of games they could see each other, and during a second round they could not. The results showed that when people’s heart rate and skin conductance level aligned, they cooperated more successfully. Interestingly, for skin conductance level synchrony to boost cooperation, face to face contact was essential. The effect of heart rate synchrony on cooperation was context independent. Skin conductance level, but not heart rate, tended to closely correlate with changes in pupil size and we discuss how the pupil might provide a window to partners’ sympathetic arousal. These findings show how unconscious mechanisms guide social behavior and emphasize the importance of studying social processes between rather than within individuals in real-life interactions.Significance StatementHuman cooperation is remarkable in its scale, complexity, and efficiency. However, whereas people think of themselves as rational agents, they actually partly base their decision to cooperate with someone on gut feelings. These feelings are informed by non-verbal expressions that are picked up implicitly and that synchronize across interaction partners. For the first time, we show that the alignment of people’s arousal over multiple rounds of the Prisoners’ dilemma game predicts cooperative success. Through synchrony, partners converge emotionally, fostering understanding and bonding, which are key ingredients when it comes to successful cooperation. This suggests that successfully cooperating does not depend on individuals, but on the connection between individuals, emphasizing the importance of studying social decision-making processes in real-life settings.

Emotional reactivity and recovery are crucial for maintaining well-being. It remains unknown, however, to what extent emotion modulates the time course of recovery assessed using a simple categorization task and how this varies based on individual differences in worry. To address these questions, 35 participants viewed emotional pictures, followed by abstract greeble targets, which were to be categorized. Greebles were presented between 100 ms and 4,000 ms after picture offset. Physiological measures including skin conductance level and the corrugator supercilii were recorded and served as indicators of responsivity to emotional pictures. Measures of reaction time (RT) and accuracy scores were taken as indicators of the impact of emotion on facilitation or interference to the greeble target. Effects of interference and facilitation were observed up to 4,000 ms after emotional pictures on RT and accuracy scores. High worry was associated with greater (1) corrugator supercilii and skin conductance level to negative versus positive and neutral pictures and (2) interference from emotional pictures on accuracy scores. Overall, these findings suggest that subsequent processing is still impacted up to 4,000 ms after the offset of emotional pictures, particularly for negative events in individuals with high worry.

SummaryPrevious research has demonstrated a different psychophysiological response of schizophrenic patients depending on whether their key relative was rated high or low on Expressed Emotion (EE). A case assessment is described in which a young man suffering from schizophrenia, who lived with both a high EE and a low EE parent, was tested psychophysiologically in their presence using an ABAC design. The patient demonstrated a significantly higher amount of spontaneous activity in skin conductance level when the high EE parent was present. The high EE parent also demonstrated a greater perceived inability to cope, and a higher level of personal distress.
