Learned Symptom-Specific Fear Toward a Visceral Sensation and Its Impact on Perceptual Habituation
OBJECTIVE: Impaired habituation of bodily sensations has been suggested as a contributing factor to chronic pain. We examined in healthy volunteers the influence of fear learning toward a nonpainful sensation in the esophagus on the perceptual habituation of this sensation. METHODS: In a homoreflexive fear learning paradigm, nonpainful electrical sensations in the esophagus were used as a conditioned stimulus (CS). This sensation was presented 42…
Leveraging Vagally Mediated Heart Rate Variability as an Actionable, Noninvasive Biomarker for Self-Regulation
This contribution highlights the significance of using vagally-mediated heart rate variability (vmHRV), a general indicator of adaptation, as an actionable biomarker to assess and enhance self-regulation abilities in individuals and organizations. The paper reviews the state-of-the-art on vmHRV and introduces various techniques to enhance vmHRV, including slow-paced breathing, the diving reflex, transcutaneous vagus nerve stimulation (tVNS), tran…
Relationship Between Different Experimental Measures of Distorted Symptom Perception in Functional Syndrome Patients
OBJECTIVE: Patients with functional somatic syndromes show reduced correspondence between induced physiological changes and self-reported symptoms in a rebreathing paradigm, as well as elevated symptoms unrelated to physiological changes after induction of negative affective states in an affective picture-viewing paradigm. Detailed results of both paradigms separately were published elsewhere. The main goal of the current report is to describe th…
Interoception and Mental Health
Interoception refers to the process by which the nervous system senses, interprets, and integrates signals originating from within the body, providing a moment-by-moment mapping of the body's internal landscape across conscious and unconscious levels. Interoceptive signaling has been considered a component process of reflexes, urges, feelings, drives, adaptive responses, and cognitive and emotional experiences, highlighting its contributions to t…
The Influence of Pain-Related Expectations on Intensity Perception of Nonpainful Somatosensory Stimuli
OBJECTIVE: The extent to which pain-related expectations, known to affect pain perception, also affect perception of nonpainful sensations remains unclear, as well as the potential role of unpredictability in this context. METHODS: In a proprioceptive fear conditioning paradigm, various arm extension movements were associated with predictable and unpredictable electrocutaneous pain or its absence. During a subsequent test phase, nonpainful electr…

Inducing Somatic Symptoms in Functional Syndrome Patients
OBJECTIVE: Induction of negative affective states can enhance bodily symptoms in high habitual symptom reporters among healthy persons and in patients with irritable bowel syndrome. The aims of this study were to replicate this effect in patients with fibromyalgia and chronic fatigue syndrome and to investigate the role of moderators, focusing on alexithymia, negative affectivity, and absorption. METHODS: Patients with fibromyalgia and/or chronic…
The Specificity of Health-Related Autobiographical Memories in Patients With Somatic Symptom Disorder
OBJECTIVE: Patients with somatic symptom disorder (SSD) have persistent distressing somatic symptoms that are associated with excessive thoughts, feelings, and behaviors. Reduced autobiographical memory specificity (rAMS) is related to a range of emotional disorders and is considered a vulnerability factor for an unfavorable course of pathology. The present study investigated whether the specificity of health-related autobiographical memories is …

Influence of Interoceptive Fear Learning on Visceral Perception
OBJECTIVES: Interoceptive fear learning and generalization have been hypothesized to play a key role in unexplained abdominal and esophageal pain in patients with functional gastrointestinal disorders. However, there is no experimental evidence demonstrating that fear learning and generalization to visceral sensations can be established in humans and alter visceral perception. METHODS: In a novel fear learning-generalization paradigm, an innocuou…
Symptom Perception, Awareness and Interpretation
Peak-End Memory Bias in Laboratory-Induced Dyspnea
OBJECTIVE: Memory for unpleasant experiences is dominated by intensity at the experience's peak and end, with a relative neglect for its duration. Therefore, unpleasant somatic experiences are expected be remembered as less aversive when they end gradually rather than abruptly, even when they last longer (i.e., the "peak-end effect"). We investigated the peak-end effect for dyspnea in healthy participants and in patients with medically unexplaine…
Feeling Lightheaded
Objective: The main aims of this study were a) to investigate the relationship between lightheadedness and cerebral blood flow velocity (CBFv) during hyperventilation-induced hypocapnia, and b) to investigate whether and why the relationship between lightheadedness and CBFv may change after several episodes of this sensation. Methods: Three hypocapnic and three normocapnic overbreathing trials were administered in a semirandomized order to health…
Acquired Lightheadedness in Response to Odors After Hyperventilation
OBJECTIVE: This study aimed to investigate whether lightheadedness in response to odors could be acquired through previous associations with hyperventilation-induced hypocapnia. METHODS: Diluted ammonia and acetic acid served as conditional odor cues (CSs) in a differential associative learning paradigm. Hyperventilation-induced hypocapnia (unconditional stimulus [US]) was used to induce lightheadedness. In a training phase, participants (n = 28)…
Can Subjective Asthma Symptoms Be Learned
Objective: We investigated whether perception of subjective asthma symptoms can be brought under control of biomedically irrelevant cues in the environment, i.e., whether subjective asthma symptoms can be learned in response to harmless stimuli. Methods: Twenty patients with asthma and 20 healthy participants were presented with two placebo-inhalers presented as new chemicals for diagnosing asthma. One inhaler was coupled three times with rebreat…
Imagined Risk of Suffocation as a Trigger for Hyperventilation
OBJECTIVE: Although hyperventilation has been hypothesized to play a role in many pathologies, its critical triggers remain poorly understood. The present experiment aimed to test whether stronger hyperventilation responses occur in response to suggested risk of suffocation compared with other fearful situations in high- and low-trait anxious women. METHODS: Fractional end-tidal CO2-concentration (FetCO2), respiratory frequency, and inspiratory v…

Resting End-Tidal CO2 and Negative Affectivity
OBJECTIVE: Dhokalia, Parsons, and Anderson (Psychosom Med 1998;60:33-37) found a positive correlation between a trait measure of negative affectivity (NA; neuroticism) and resting end-tidal fractional concentration of CO2 (FetCO2) (fractional-concentration of end-tidal carbon dioxide) in a nonclinical sample. This contrasts sharply with studies reporting a negative association of FetCO2 with state measures of NA and with studies reporting no or a…
Media Warnings About Environmental Pollution Facilitate the Acquisition of Symptoms in Response to Chemical Substances
OBJECTIVE: Previous studies showed that somatic symptoms can be acquired in response to chemical substances using an associative learning paradigm, but only when the substance was foul smelling and not when it smelled pleasant. In this study, we investigated whether warnings about environmental pollution would facilitate acquiring symptoms, regardless of the pleasantness of the smell. METHOD: One group received prior information framing the study…
Generalization of Acquired Somatic Symptoms in Response to Odors
OBJECTIVE: Somatic symptoms that occur in response to odors can be acquired in a pavlovian conditioning paradigm. The present study investigated 1) whether learned symptoms can generalize to new odors, 2) whether the generalization gradient is linked to the affective or irritant quality of the new odors, and 3) whether the delay between acquisition and testing modulates generalization. METHODS: Conditional odor stimuli (CS) were (diluted) ammonia…
