BACKGROUND: Light interventions typically exert their mood-related effects during morning bright light exposures over several weeks. Evidence about immediate ambient room light effects on depressed individuals is still sparse. OBJECTIVE: The present study aimed at examining the acute effects of a single moderately bright room light exposure on mood, and behavioural and cardiac stress reactions of mildly depressed geriatric inpatients during a short cognitive stimulation and while resting...

An important question in the reading literature regards the nature of the semantic information readers can extract from the parafovea (i.e., the next word in a sentence). Recent eye-tracking findings have found a semantic parafoveal preview benefit under many circumstances, and findings from event-related brain potentials (ERPs) also suggest that readers can at least detect semantic anomalies parafoveally (Barber, Van der Meij, & Kutas, Psychophysiology, 50(1), 48-59, 2013). We use ERPs to ask whether fine-grained aspects of semantic expectancy can affect the N400 elicited by a word appearing in the parafovea...

BACKGROUND: Although there is solid evidence for the efficacy of in vivo and virtual reality (VR) exposure therapy for a specific phobia, there is a significant debate over whether techniques promoting distraction or relaxation have impairing or enhancing effects on treatment outcome. In the present pilot study, we investigated the effect of diaphragmatic breathing (DB) as a relaxation technique during VR exposure treatment. METHOD: Twenty-nine patients with aviophobia were randomly assigned to VR exposure treatment either with or without diaphragmatic breathing (six cycles per minute)...

Being touched is known to affect emotion, and even a casual touch can elicit positive feelings and affinity. Psychophysiological studies have recently shown that tactile primes affect visual evoked potentials to emotional stimuli, suggesting altered affective stimulus processing. As, however, these studies approached emotion from a purely unidimensional perspective, it remains unclear whether touch biases emotional evaluation or a more general feature such as salience. Here, we investigated how simple tactile primes modulate event related potentials (ERPs), facial EMG and cardiac response to pictures of facial expressions of emotion...

A large body of research on gender differences in response to erotic stimuli has focused on genital and/or subjective sexual arousal. On the other hand, studies assessing gender differences in emotional psychophysiological responding to sexual stimuli have only employed erotic pictures of male-female couples or female/male nudes. The present study aimed at investigating differences between gynephilic men and androphilic women in emotional responding to visual sexual stimuli depicting female-male, female-female and male-male couples...

We are remarkably adept at inferring the consequences of our actions, yet the neuronal mechanisms that allow us to plan a sequence of novel choices remain unclear. We used functional magnetic resonance imaging (fMRI) to investigate how the human brain plans the shortest path to a goal in novel mazes with one (shallow maze) or two (deep maze) choice points. We observed two distinct anterior prefrontal responses to demanding choices at the second choice point: one in rostrodorsal medial prefrontal cortex (rd-mPFC)/superior frontal gyrus (SFG) that was also sensitive to (deactivated by) demanding initial choices and another in lateral frontopolar cortex (lFPC), which was only engaged by demanding choices at the second choice point...

Current approaches to assess interoception of respiratory functions cannot differentiate between the physiological basis of interoception, i.e. visceral-afferent signal processing, and the psychological process of attention focusing. Furthermore, they typically involve invasive procedures, e.g. induction of respiratory occlusions or the inhalation of CO2-enriched air. The aim of this study was to test the capacity of startle methodology to reflect respiratory-related afferent signal processing, independent of invasive procedures...

Previous studies on prospective memory (PM), defined as memory for future intentions, suggest that psychological stress enhances successful PM retrieval. However, the mechanisms underlying this notion remain poorly understood. We hypothesized that PM retrieval is achieved through interaction with autonomic nervous activity, which is mediated by the individual accuracy of interoceptive awareness, as measured by the heartbeat detection task. In this study, the relationship between cardiac reactivity and retrieval of delayed intentions was evaluated using the event-based PM task...

BACKGROUND: Borg Rating of Perceived Exertion Scale (RPE) is a psychophysiological measurements that translates physical stimuli to a psychological construct, which is perceived exertion. Its use is simple and it represents the effort perception. Each number of the scale is associated with a heart rate or percentage of maximal oxygen consumption (VO2max), which estimates the intensity of exercise. AIM: To validate RPE scale in patients with type 2 diabetes mellitus (DM2)...

The impact of multiple sclerosis (MS) diagnosis on newly diagnosed individuals remains so far little explored. Our aim is to outline affective, personality and quality of life (QoL) correlates of MS patients shortly after MS diagnosis. Thirty-eight (22 F and 16 M) newly-diagnosed MS patients (mean interval from diagnosis communication 4.7 ± 3.8 months, range 1-12 months) underwent the Montgomery-Åsberg Depression Rating Scale and a comprehensive psychological evaluation: Beck Depression Inventory-II, State-Trait Anxiety Inventory, Psychophysiological Questionnaire-Revised, Fear Survey Schedule, Maudsley Obsessional-Compulsive Questionnaire, Impact of Event Scale-Revised, Personal Meaning Questionnaire, Problem Solving Inventory and Multiple Sclerosis Quality of Life-54...

Extant literature suggests that oppositional defiant (ODD) and callous-unemotional (CU) behaviors in childhood and adolescence are associated with distinct patterns of psychophysiological functioning and that individual differences in these patterns have implications for developmental pathways to disorder. Very little is known about the associations between psychophysiological functioning in infancy and later ODD and CU behaviors. This study examined associations between basal autonomic nervous system (ANS) functioning in infancy and ODD and CU behaviors in later childhood...

An increasing number of studies have implicated network functional connectivity with addiction. Yet, none have examined functional connectivity as a potential mechanism of adolescent behavior change. We examined the underlying neural mechanisms of a promising treatment for adolescents, motivational interviewing (MI). We began by employing psychophysiological interaction (PPI) to evaluate network response in a sample of adolescent cannabis users (N = 30). Next, we examined correlations between network connectivity and clinical metrics of treatment outcome...

OBJECTIVES: Panic disorder (PD) is common among asthmatics and is associated with worse asthma outcomes. This may occur due to psychophysiological factors or to cognitive/affective factors. This study evaluated the impact of panic attacks (PAs) on bronchoconstriction and subjective distress in asthmatics with and without PD. METHODS: A total of 25 asthmatics (15 with PD who had a PA [PD/PA], 10 without PD who didn't have a PA [noPD/noPA]) were recruited from an outpatient clinic...

Youth and adults with Attention-Deficit/Hyperactivity Disorder (ADHD) experience academic and social impairment and engage in risky behaviors. Emotion dysregulation (ED) is associated with ADHD and may contribute to these impairments and behaviors. Although many measures of ED exist, little is known about the physiological bases of ED, in the context of ADHD. In a large sample of children (M age = 9.01 years; 62% male) with (n = 48) and without (n = 56) ADHD, we examined (1) the correspondence between parent-reported ED and heart rate variability (HRV) - a psychophysiological marker of parasympathetic engagement and (2) whether parent-reported ED is predicted by HRV above and beyond ADHD...

BACKGROUND: This study investigated differences in kinematic and spatiotemporal variables in Labrador retrievers during introduction to treadmill walking, with the aim to determine the time required for them to become habituated. Twenty-five healthy, treadmill-naive Labrador retrievers participated in the study. The total angular displacement of the carpus, elbow, tarsus and stifle, as well as stride time and stance duration were calculated from the 3-D tracking of skin mounted reflective markers recorded with 6 infrared light emitting video cameras at 240 Hz...

Hostility is a risk factor for cardiovascular events. When challenged, individuals high on hostility exhibit a hyperreactive psychophysiological response to stressors, thereby increasing risk for developing cardiovascular disease. However, low resting heart rate (HR) is associated with physical aggression and hostility in children, adolescents, and adults. Based on a community sample of 296 men (mean age = 32.0), we (a) address whether aggression/hostility relates to physical health through relationships with cardiovascular levels at rest and in response to stressors, and (b) determine how relations between aggression and health are altered by including psychophysiological indices in statistical models...

This study investigates whether individual differences in attachment status can be detected by electrophysiological responses to loss-themed pictures. The Adult Attachment Interview (AAI) was used to identify discourse/reasoning lapses during the discussion of loss experiences via death that place speakers in the Unresolved/disorganized AAI category. In parents, Unresolved AAI status has been associated with Disorganized infant Strange Situation response, a known risk factor for psychopathology (e.g., internalizing/externalizing/dissociation)...

BACKGROUND: Increases in inhibitory errors in heavy drinkers are established; less well-studied is whether heavy drinkers are aware of these errors in performance. Reductions in error detection and awareness limit the possibility for remedial action to be taken, and have implications for substance abusers seeking to control use: failure to monitor and/or adjust ongoing behaviour may be linked to using more or more often than intended, and failing to adjust behaviour after a slip. Here we report the first study of both inhibitory control and error awareness in young heavy drinkers, using behavioural and psychophysiological measures...
