Manualized psychodynamic-interactional group therapy for the treatment of somatoform pain disorders.

2010

Medically unexplained and clinically significant symptoms of pain are highly prevalent in the general population. More than one third of all patients in general practices and various departments of hospitals suffer from somatoform disorders with pain being the main complaint of 70% of these patients. This treatment manual is the first disorder-specific, psychodynamically oriented treatment for these patients. Based on psychodynamic-interactional group psychotherapy, it focuses on disorder-specific aspects as well as on psychic and interpersonal problems which have resulted from adverse childhood experiences and insecure attachment. In three treatment phases comprising an “information and mo…

Competitive active video games: Physiological and psychological responses in children and adolescents

2015

Recent strategies to reduce sedentary behaviour in children include replacing sedentary screen time for active video games. Active video game studies have focused principally on the metabolic consumption of a single player, with physiological and psychological responses of opponent-based multiplayer games to be further evaluated.To determine whether adding a competitive component to playing active video games impacts physiological and psychological responses in players.Sixty-two healthy Caucasian children and adolescents, nine to 14 years years of age, completed three conditions (8 min each) in random order: treadmill walking, and single and opponent-based Kinect active video games. Affect,…

Patterns of sympathetic responses induced by different stress tasks.

2008

Stress tasks are used to induce sympathetic nervous system (SNS) arousal. However, the efficacy and the patterns of SNS activation have not been systematically compared between different tasks. Therefore, we analyzed SNS activation during the following stress tasks: Presentation of negative, positive, and – as a control – neutral affective pictures, Color-Word interference test (CWT), mental arithmetic under time limit, singing a song aloud, and giving a spontaneous talk. We examined 11 healthy subjects and recorded the following SNS parameters: Activation of emotional sweating by quantitative sudometry, skin vasoconstriction by laser-Doppler flowmetry, heart rate by ECG, blood pressure by …

Post-encoding stress does not enhance memory consolidation: The role of cortisol and testosterone reactivity

2020

In contrast to the large body of research on the effects of stress-induced cortisol on memory consolidation in young people, far less attention has been devoted to understanding the effects of stress-induced testosterone on this memory phase. This study examined the psychobiological (i.e., anxiety, cortisol, and testosterone) response to the Maastricht Acute Stress Test and its impact on free recall and recognition for emotional and neutral material. Thirty-seven healthy young men and women were exposed to a stress (MAST) or control task post-encoding, and 24 h later, they had to recall the material previously learned. Results indicated that the MAST increased anxiety and cortisol levels, b…

The Temporal Development of Early and Late CNV in a Simple Discrimination Paradigm: the Effects of Motor Preparation and Average Reaction Time

1980

Publisher Summary This chapter discusses the temporal development of early and late contingent negative variation (CNV) in a simple discrimination paradigm. The CNV typically arises when a warning stimulus is paired with an imperative stimulus which, in turn, is followed by a motor reaction. If the interstimulus interval is less than approximately 2 sec the CNV begins immediately after the positive deflection (P300) following the warning stimulus. It may appear as a steadily rising negative potential shift that reaches its peak with the presentation of the imperative stimulus, or as sustained negativity throughout the rest of the foreperiod. If the interstimulus interval is extended beyond …

Cortical Patterns of Pleasurable Musical Chills Revealed by High-Density EEG

2020

Music has the capacity to elicit strong positive feelings in humans by activating the brain’s reward system. Because group emotional dynamics is a central concern of social neurosciences, the study of emotion in natural/ecological conditions is gaining interest. This study aimed to show that high-density EEG (HD-EEG) is able to reveal patterns of cerebral activities previously identified by fMRI or PET scans when the subject experiences pleasurable musical chills. We used HD-EEG to record participants (11 female, 7 male) while listening to their favorite pleasurable chill-inducing musical excerpts; they reported their subjective emotional state from low pleasure up to chills. HD-EEG results…

Quantifying Intermodal Distraction by Emotion During Math Performance: An Electrophysiological Approach

2019

Emotionally engaging stimuli are powerful competitors for limited attention capacity. In the cognitive neuroscience laboratory, the presence of task-irrelevant emotionally arousing visual distractors prompts decreased performance and attenuated brain responses measured in concurrent visual tasks. The extent to which distraction effects occur across different sensory modalities is not yet established, however. Here, we examined the extent and time course of competition between a naturalistic distractor sound and a visual task stimulus, using dense-array electroencephalography (EEG) recordings from 20 college students. Steady-state visual evoked potentials (ssVEPs) were quantified from EEG, e…

2017

The mere presence of a depiction of eyes can elicit a sense of being watched in the perceiver. To this date, the factors affecting the intensity of this sense of being watched, however, have not been investigated. In the present experiment, we tested the impact of two potentially relevant variables: arousal (manipulated using specific musical pieces) and duration of the perceptual episode (manipulated using presentation times of 200 ms and 10 s, respectively). We asked participants to report how intensely they felt being watched while we exposed them to various observation cues ranging from human eyes to surveillance cameras. We found that, on average, reported intensities were higher if pa…

Intensity of Respiratory Cortical Arousals Is a Distinct Pathophysiologic Feature and Is Associated with Disease Severity in Obstructive Sleep Apnea …

2021

Background: We investigated whether the number, duration and intensity of respiratory arousals (RA) on C3-electroencephalographic (EEG) recordings correlate with polysomnography (PSG)-related disease severity in obstructive sleep apnea (OSA) patients. We also investigated if every patient might have an individual RA microstructure pattern, independent from OSA-severity. Methods: PSG recordings of 20 OSA patients (9 female

Affective Arousal During Blaming in Couple Therapy: Combining Analyses of Verbal Discourse and Physiological Responses in Two Case Studies

2016

Blaming one’s partner is common in couple therapy and such moral comment often evokes affective arousal. How people attune to each other as whole embodied beings is a current focus of interest in psychotherapy research. This study contributes to the literature by looking at attunement during critical moments in therapy interaction. Responses to blaming in verbal dialogue and at the level of the autonomic nervous system (ANS) were investigated in two couple therapy cases with a client couple and two therapists. Video-recorded couple therapy sessions were analyzed using discursive psychology and a narrative approach. The use of positioning, a discourse analytic tool, was also studied. ANS res…
