Abstract We examined the use of smoothing to enhance the detection of response coupling from the activity of different response systems. Three different types of moving average smoothers were applied to both simulated interbeat interval (IBI) and electrodermal activity (EDA) time series and to empirical IBI, EDA, and facial electromyography time series. The results indicated that progressive smoothing increased the efficiency of the detection of response coupling but did not increase the probability of Type I error. The power of the smoothing methods depended on the response characteristics. The benefits and use of the smoothing methods to extract information from psychophysiological time series are discussed.

Perceived Social Isolation

As social beings, humans harbor an evolved capacity for loneliness—perceived social isolation. Feelings of loneliness are associated with aberrant affective and social processing, as well as deleterious physiological dysregulation. We investigated how loneliness affects spontaneous facial mimicry (SFM), an interpersonal resonance mechanism involved in social connection and emotional contagion. We used facial electromyography (fEMG) to measure activity of the zygomaticus major (“smiling muscle”) and corrugator supercilii (“frowning muscle”) while participants viewed emotional stimuli, such as video clips of actors expressing anger, fear, sadness, or joy, and emotional IAPS images. We also measured self-reported loneliness, depression, and extraversion levels. Evidence for SFM was found in greater fEMG activity of the zygomaticus and corrugator to positive and negative emotions, respectively. However, individuals reporting higher levels of loneliness lacked SFM for expressions of joy. Loneliness did not affect deliberate mimicry activity to the same expressions, or spontaneous reactions to positive, negative, or neutral IAPS images. Depression and extraversion did not predict any differences in fEMG responses. We argue that impaired automaticity of “smiling back” at another—a faulty interpersonal resonance response—represents a pervasive behavioral mechanism that likely contributes to negative social and emotional consequences of loneliness and may facilitate loneliness contagion.
