Single session anodal transcranial direct current stimulation on different cortical areas: Effects on pain modulation in healthy subjects.
Journal of Psychophysiology, Vol 37(2), 2023, 101-109; doi:10.1027/0269-8803/a000311Transcranial direct current stimulation (tDCS) studies in healthy volunteers have shown conflicting results in terms of modulation in pain thresholds. The aim of this study was to investigate how single session anodal tDCS and modulated tDCS (mtDCS) of distinct cortical areas affected pain and perception thresholds in healthy participants. Five different stimulation conditions were applied at different cortical sites to 20 healthy volunteers to investigate the effects of tDCS and mtDCS (20 Hz) on pain and perception thresholds. TDCS over th...

Influence of bilingualism on behavioral and electrophysiological parameters of cognitive control: No clear effects of immersion, stimulus language, and word similarity.
Journal of Psychophysiology, Vol 37(2), 2023, 88-100; doi:10.1027/0269-8803/a000310Bilingualism has been associated with better cognitive control as compared to monolingualism. However, the robustness of the respective findings is subject to a recent debate, and moderators should be taken into consideration. We reasoned that groups immersed in their second language should show a greater bilingual advantage in cognitive control as compared to non-immersed participants. Further, stimulus language (first or second language), word similarity in the two languages (similar or dissimilar), as well as congruency between ink and wo...

Avoidant personality disorder symptoms and cardiovascular reactivity to psychological stress tasks with increasing cognitive demands.
This study aimed to investigate whether and how avoidant personality disorder symptoms are related to cardiovascular reactivity to stress tasks with different levels of cognitive demands. The revised Chinese edition of the avoidant personality disorder subscale of Personality Diagnosed Questionnaire-4 + (PDQ-4 +) was administered to 222 undergraduate students randomly assigned to psychological stress tasks (i.e., mental arithmetic tasks) with low, moderate, or high cognitive demands (manipulated by task difficulty), during which their physiological data were continuously collected. Results showed that avoidant personality ...

Meta-analysis and systematic review of resting-state high-frequency heart rate variability in binge-eating disorder.
Journal of Psychophysiology, Vol 37(1), 2023, 50-63; doi:10.1027/0269-8803/a000307Binge-eating disorder (BED) is associated with a greater risk for cardiac problems and co-occurring health conditions. Resting-state measures of high-frequency heart rate variability (HF-HRV), which is a physiological proxy of self-regulatory neural functioning, may aid understanding of health risks. We systematically reviewed and meta-analyzed the literature on HF-HRV in individuals with BED and without BED. Six studies were reviewed in the qualitative synthesis, and five studies assessing HRV in individuals with BED (n = 153) and without BE...

The impact of pain on subsequent effort and cognitive performance.
This study investigated the influence of a first task, including painful vs. non-painful thermal stimuli, on effort-related cardiac response and performance in a subsequent moderately difficult cognitive task. Drawing on the hypothesis that experiencing pain should recruit cognitive resources (such as attention and working memory) and reduce perceived ability, we predicted lower task performance and/or stronger compensatory effort in the subsequent cognitive task after the painful than after the non-painful first task. Results support our predictions regarding the effect of pain on subsequent cognitive performance, which w...

Speech related anxiety in adults who stutter.
Journal of Psychophysiology, Vol 37(1), 2023, 25-38; doi:10.1027/0269-8803/a000305The relationship between anxiety and stuttering has always been a topic of debate with a great emphasis on research focused on examining whether speech-related anxiety can exacerbate stuttering. This investigation compares some speech-related anticipatory anxiety indices in fluent and dysfluent utterances in adults who stutter (AWS). We scored the level of cognitive speech-related anxiety (anticipatory anxiety) using a self-reporting method and also evaluated the autonomic aspects of anxiety (state anxiety) through recording changes in Galvan...

Time, consciousness, and the readiness potential.
This article discusses time, consciousness, and the readiness potential (RP) Time is a dimension of the Universe in modern physics, yet whether time is a physical entity or a subjective representation seems an unsettled issue. There are evident discrepancies between the time duration of, or intervals between, the elements of our subjective experience and the timing and duration of neuronal functions and mechanisms. The description of a recordable negative macropotential originating in supplementary motor and motor cortices one to two seconds before a voluntary action provided evidence that setting the movement organization...

Prefrontal neuronal activities during active retrieval of information from long-term memory.
Journal of Psychophysiology, Vol 37(1), 2023, 39-49; doi:10.1027/0269-8803/a000306Single-neuron studies performed in the primate prefrontal cortex (PFC) revealed that retaining information in working memory (WM) is associated with sustained firing during the delay period in a match-to-sample task. On the other hand, single-neuron studies using a pair-association task have shown that retrieving information from long-term memory (LTM) is related to two kinds of neural activities: decreasing activity representing information linked to the sample stimulus and increasing activity predicting information for the forthcoming match...

“A preliminary investigation of ERP components of attentional bias in anxious adults using temporospatial principal component analysis”: Correction to Gupta, Kujawa, & Vago, 2021.
Reports an error in "A preliminary investigation of ERP components of attentional bias in anxious adults using temporospatial principal component analysis" by Resh S. Gupta, Autumn Kujawa and David R. Vago (Journal of Psychophysiology, 2021, Vol 35[4], 223-236). In the article, the authors detected an error in the “Split-Half Reliability” section. The software used to perform the Spearman-Brown split-half correlation analyses outputted the Spearman rho, and not the Spearman-Brown, statistics. The authors re-calculated the Spearman-Brown split-half reliability values for all components, and it is excellent for all cases...

Measures of brain function and the spectrum of disorder(s) concept.
This article discusses measures of brain function and the spectrum of disorder(s) concept. The need to account for the variability in combination, relevance, and severity of the elements of a diagnostic class has promoted the concept of “spectrum of disorders” associating pathological conditions that occur on a continuum and share symptoms and features that can differ in form and degree. The extent to which frailty, as a label, exceeds the range of multimorbidity common among the elderly remains undefined. In the case of the metabolic syndrome or metabolic spectrum, this approach has been criticized for being an over i...

Psychological stress = Physiological stress? An experimental study with prospective teachers.
Journal of Psychophysiology, Vol 37(1), 2023, 12-24; doi:10.1027/0269-8803/a000301The present study analyzed experimentally the association between the experience of psychological stress and the physiological stress response of prospective teachers. The experienced stress was assessed by self-reported data. Cortisol concentrations via saliva samples reflected the physiological response. The results show no difference between the stress and the control group in the experience of psychological stress. However, the stress group had significantly increased cortisol concentrations compared to the control group. The study could ...

Relationship of interoceptive accuracy with risky decision-making and treatment outcomes in male patients with alcohol use disorder.
This study focused on the premise that interoceptive accuracy (IAc), as the primary construct of IA, is implicated in SUD and that poor IAc is linked to risky decision-making and adversely affects treatment outcomes. Eighty-five patients with alcohol use disorder (AUD) (current severity: moderate or severe) and 87 healthy control subjects were enrolled in the present study. All participants performed the heart rate tracking task and a computerized version of the Iowa gambling task (IGT). Characteristics of patients’ addiction profiles were assessed with the Addiction Profile Index (API) Clinical Form. IAc and IGT scores ...

Higher resting cardiovagal activity predicts larger decrease of depressive symptoms in inpatients treated for stress-related depression.
Journal of Psychophysiology, Vol 36(4), 2022, 254-266; doi:10.1027/0269-8803/a000299Depression is one of the most prevalent mental disorders, with treatment outcomes generally being unsatisfactory. The identification of outcome predictors could contribute to improving diagnosis, treatment, and outcome. Heart rate variability (HRV), an index of cardiovagal activity, has been proposed as a potential correlate of depression as well as a predictor of treatment effectiveness. The aim of the present study was to examine if HRV at baseline could predict the outcome of inpatient treatment for stress-related depressive disorder (SR...
