Emotional inertia and external events the roles of exposure reactivity and recovery
Emotion, 2015Co-Authors: Peter Koval, Dominique Champagne, Yasemin Erbas, Annette Brose, Marlies Houben, Peter KuppensAbstract:Increased moment-to-moment predictability, or inertia, of negative affect has been identified as an important dynamic marker of psychological maladjustment, and increased vulnerability to depression in particular. However, little is known about the processes underlying Emotional inertia. The current article examines how the Emotional context, and people’s responses to it, are related to Emotional inertia. We investigated how individual differences in the inertia of negative affect (NA) are related to individual differences in exposure, reactivity, and recovery from Emotional events, in daily life (assessed using experience sampling) as well as in the lab (assessed using an Emotional Film-Clip task), among 200 participants commencing their first year of tertiary education. This dual-method approach allowed us to assess affective responding on different timescales, and in response to standardized as well as idiographic Emotional stimuli. Our most consistent finding, across both methods, was that heightened NA inertia is related to decreased NA recovery following negative stimuli, suggesting that higher levels of inertia may be mostly driven by impairments in affect repair following negative events.

airway reactivity in response to repeated Emotional Film Clip presentation in asthma
Biological Psychology, 2017Co-Authors: Thomas Janssens, Ashton M Steele, David Rosenfield, Thomas RitzAbstract:Emotional stimuli elicit airway constriction in individuals with asthma and in healthy individuals, but little is known about effects of repeated stimulation. We therefore explored the effect of repeated emotion induction on respiratory resistance (Rrs) using unpleasant, high-arousal surgery Films and investigated effects of respiration and Emotional reactivity. Twenty-six participants (13 with asthma) watched a series of 12 short, 45-s surgery Films followed by 2-min recovery periods. Rrs assessed with impulse oscillometry was significantly elevated during Films in both groups compared to baseline and recovered quickly after that. No habituation of airway responses occurred. Rrs was higher in participants who felt more aroused and less in control when watching the Films. Changes in Rrs remained significant when controlling for changes in respiration or Emotional experience. Thus, although unpleasant stimuli lead to elevated Rrs, airway obstruction is not exacerbated with repeated stimulation due to a fast return to baseline after stimulation.

skin conductance and memory fragmentation after exposure to an Emotional Film Clip in depersonalization disorder
Psychiatry Research-neuroimaging, 2010Co-Authors: Timo Giesbrecht, Harald Merckelbach, Kim Van Oorsouw, Daphne SimeonAbstract:Abstract It is often assumed that when confronted with an Emotional event, patients with DPD inhibit information processing. It is also thought that this fosters memory fragmentation. This hypothesis has not been tested in chronic depersonalization. The aim of this study was to investigate the temporal pattern of autonomic responding to Emotional material in depersonalization disorder, along with concomitant deficits in subjective and objective memory formation (i.e., difficulties to form a coherent narrative consisting of an ordered sequence of events). Participants with depersonalization disorder ( n =14) and healthy control participants ( n =14) viewed an Emotional video Clip while their skin conductance (SC) levels were measured. Peritraumatic dissociation was measured before and after the Clip, and memory performance was measured 35min after viewing. Compared to controls, depersonalized participants exhibited a distinctly different temporal pattern of autonomic responding, characterized by an earlier peak and subsequent flattening of SCLs. Maximum SCLs did not differ between the two groups. Moreover, unlike the control group, depersonalized participants showed no SC recovery after Clip offset. In terms of memory performance, patients exhibited objective memory fragmentation, which they also reported subjectively. However, they did not differ from controls in free recall performance. Apparently, Emotional responding in DPD is characterized by a shortened latency to peak with subsequent flattening and is accompanied by memory fragmentation in the light of otherwise unremarkable memory functioning.
