Temporal boundary of auditory event formation: An electrophysiological marker.

Int J Psychophysiol 2019 Apr 19. Epub 2019 Apr 19.

Institute of Cognitive Neuroscience and Psychology, Research Centre for Natural Sciences, Hungarian Academy of Sciences, Budapest, Hungary. Electronic address:

The formation of auditory events requires integration between successive sounds. There is a temporal limit below which a single sound event is perceived while above which a second perceptual event is formed. Behavioral studies applying the Temporal Order Judgment paradigm showed that this boundary is between 20 and 70 ms. Read More

Pupillometric indices of locus-coeruleus activation are not modulated following single bouts of exercise.

Int J Psychophysiol 2019 Apr 14. Epub 2019 Apr 14.

Department of Kinesiology, Michigan State University, United States of America.

Single bouts of exercise have been observed to enhance numerous domains of cognition including inhibitory aspects of cognitive control and neuroelectric indices of attention. Given that the locus-coeruleus norepinephrine system regulates alertness and attention, this system may underlie these exercise-induced enhancements. The present study used pupillometry to examine the extent to which a single bout of exercise induces changes in aspects of locus-coeruleus activation, as well as the extent to which changes in locus-coeruleus activation were associated with changes in inhibition and neuroelectric indices of attention.

Waking qEEG to assess psychophysiological stress and alertness during simulated on-call conditions.

Int J Psychophysiol 2019 Apr 10. Epub 2019 Apr 10.

Adelaide Institute for Sleep Health: Flinders Centre of Research Excellence, College of Medicine and Public Health, Flinders University, SA, Australia; NeuroSleep, Centre for Sleep and Chronobiology, Woolcock Institute of Medical Research, University of Sydney, Australia.

Introduction: On-call schedules are associated with stress and disrupted sleep. In a recent study, under non-sleep deprived conditions, low and high-stress on-call conditions did not significantly impact sleep quality but did impact next day performance. Our aim was to determine whether quantitative electroencephalography (qEEG) would reflect changes in cortical activity in on-call conditions, predicting that the high-stress condition would display faster qEEG frequencies compared with the control and low-stress condition.

Interoceptive awareness and perceived control moderate the relationship between cognitive reappraisal, self-esteem, and cardiac activity in daily life.

Int J Psychophysiol 2019 Apr 6. Epub 2019 Apr 6.

Department of Clinical Psychology and Psychotherapy, University of Ulm, Germany.

Cognitive reappraisal has been discussed to dampen emotional experience and foster health and well-being. Recent theorizing suggests that the benefits of reappraisal might depend on the feasibility to exert control in a given situation and the ability of an individual to sensitively attend to organismic cues (interoception). This study examined the interplay of habitual reappraisal, interoceptive awareness and perceived control on psychological (self-esteem) and physiological (heart rate variability) adjustment in daily life.

Int J Psychophysiol 2019 Apr 5;140:15-25. Epub 2019 Apr 5.

Department of Psychology, Henan University, Kaifeng 475004, China. Electronic address:

We investigated whether the effect of the valence and arousal of less or more affective experiential words on affective priming using event-related potentials (ERPs). The stimuli included less affective experiential (LE) words (Experiment 1) and more affective experiential (ME) words (Experiment 2) that were organized in an orthogonal design, with valence (positive and negative) and arousal (low and high) as factors in a lexical decision task. In Experiment 1, the results revealed no obvious effect of affective priming on response times (RTs) or ERPs for LE words. Read More

Brain event-related potentials predict individual differences in inhibitory control.

Int J Psychophysiol 2019 Mar 30. Epub 2019 Mar 30.

School of Psychology, Trinity College Dublin, Dublin 2, Ireland; Global Brain Health Institute, Trinity College Dublin, Dublin 2, Ireland. Electronic address:

Stop-signal reaction time (SSRT), the time needed to cancel an already-initiated motor response, quantifies individual differences in inhibitory control. Electrophysiological correlates of SSRT have primarily focused on late event-related potential (ERP) components over midline scalp regions from successfully inhibited stop trials. SSRT is robustly associated with the P300, there is mixed evidence for N200 involvement, and there is little information on the role of early ERP components. Read More

Training gains and transfer effects after mnemonic strategy training in mild cognitive impairment: A fMRI study.

Int J Psychophysiol 2019 Mar 29. Epub 2019 Mar 29.

Old Age Research Group (PROTER), Department and Institute of Psychiatry, Faculty of Medicine, University of São Paulo, São Paulo, Brazil.

Prior work has revealed that mnemonic strategy training (MST) can enhance memory for specific content and engages regions in the frontoparietal cognitive control network. Evidence of transfer to novel content is less clear. Here, we provide secondary analysis of functional magnetic resonance imaging (fMRI) data acquired during a randomized controlled trial that compared MST to an active education control condition in patients with amnestic mild cognitive impairment (a-MCI).

Inhibitory control of emotional processing: Theoretical and empirical considerations.

Int J Psychophysiol 2019 Mar 29. Epub 2019 Mar 29.

Department of Psychology, University of California Los Angeles, Los Angeles, CA, United States; Department of Psychology, University of Illinois at Urbana-Champaign, Champaign, IL, United States; Department of Psychiatry and Biobehavioral Sciences, University of California Los Angeles, Los Angeles, CA, United States.

Although inhibitory control appears to support successful emotion regulation (ER; Joorman and Gotlib, 2010; McCabe et al., 2010), few emotion inhibition studies position themselves in the literature on ER, and even fewer ER studies reference the role of emotion inhibition. Perhaps contributing to this, the ER literature is frequently divided into implicit or "automatic" (which subsumes emotion inhibition) and explicit or "effortful" control (Braunstein et al.

Craving and substance use: Examining psychophysiological and behavioral moderators.

Int J Psychophysiol 2019 Mar 25. Epub 2019 Mar 25.

University of South Florida, USA.

Theories of substance use have emphasized the role of craving and inhibitory control in continued use, yet few studies have examined the interplay between momentary craving and inhibitory control in predicting illicit drug use in everyday life. The primary goal of this study was to examine whether individual differences in inhibitory control, indexed by laboratory-assessed electrophysiology and behavior, moderate the relation between momentary craving and alcohol and drug use assessed outside the lab using a smartphone. A secondary goal was to examine the extent of coherence in the results across different ERP components (e. Read More

Inter-participant variabilities and sample sizes in P300 and P600.

Int J Psychophysiol 2019 Mar 23;140:33-40. Epub 2019 Mar 23.

College of Comprehensive Psychology, Ritsumeikan University, 2-150, Iwakura-cho, Ibaraki, Osaka 567-8570, Japan.

Reliably and efficiently detecting physiological differences between conditions of interest is of importance in psychophysiology. In particular, when it comes to the observation of relatively small differences, such as a P600 effect, a language-related brain potential elicited by ungrammatical sentences compared to grammatical sentences, inter-participant variability is a critical factor since a larger inter-participant variability decreases statistical significance, and therefore increases the necessary sample size. The present study investigated how stable individual P600s are, at which sample sizes the P600 becomes stable, and how many participants are necessary to observe a P600 effect. Read More

Anticipating the unknown: The stimulus-preceding negativity is enhanced by uncertain threat.

Int J Psychophysiol 2019 May 19;139:68-73. Epub 2019 Mar 19.

Department of Psychology, Yale University, 2 Hillhouse Ave., New Haven, CT 06511, USA.

Anticipating the future is an important psychological process that facilitates adaptive functioning. The stimulus-preceding negativity (SPN) is an event-related potential index of anticipation that is elicited in the several hundred milliseconds before an outcome occurs. The SPN is elicited by emotional stimuli, such as electric shocks, and has been proposed to reflect emotional anticipation. Read More

Disorganization and cognitive impairment in schizophrenia: New insights from electrophysiological findings.

Int J Psychophysiol 2019 Mar 18. Epub 2019 Mar 18.

Department of Psychiatry, University of Campania "Luigi Vanvitelli", Naples, Italy.

In subjects with schizophrenia (SCZ), the disorganization dimension is a strong predictor of real-life functioning. "Conceptual disorganization" (P2), "Difficulty in abstract thinking" (N5) and "Poor attention" (G11) are core features of the disorganization factor, evaluated using the Positive and Negative Syndrome Scale. The heterogeneity of this dimension and its overlap with neurocognitive deficits are still debated. Read More

Individual differences in resting-state pupil size: Evidence for association between working memory capacity and pupil size variability.

Int J Psychophysiol 2019 Mar 17;140:1-7. Epub 2019 Mar 17.

Department of Psychology, University of Oslo, Oslo, Norway; CoE NORMENT, KG Jebsen Centre for Psychosis Research, Division of Mental Health and Addiction, Oslo University Hospital, Norway.

Dynamic non-luminance-mediated changes in pupil diameter have frequently been shown to be a reliable index for the level of arousal, mental effort, and activity in the locus coeruleus, the brainstem's noradrenergic arousal center. While pupillometry has most commonly been used to assess the level of arousal in particular psychological states or the level of engagement in cognitive tasks, some recent studies have found a relationship between average resting-state (i.e. Read More

Electrophysiological indices of amplitude modulated sounds and sensitivity to noise.

Int J Psychophysiol 2019 May 14;139:59-67. Epub 2019 Mar 14.

School of Psychology, University of Auckland, Auckland, New Zealand. Electronic address:

Annoyance to unwanted sound differs across individuals, though why noise sensitive individuals are more reactive to noise while others are more resilient remains unanswered. The Information Processing Hypothesis posits that noise sensitive individuals are vulnerable to higher-order auditory processing deficits. The aim of this study was to test the veracity of this hypothesis by documenting differences in pre-attentive auditory evoked potentials (ERP) between high noise sensitive and low noise sensitive individuals.

The difference of mild cognitive impairment in Parkinson's disease from amnestic mild cognitive impairment: Deeper power decrement and no phase-locking in visual event-related responses.

Int J Psychophysiol 2019 May 7;139:48-58. Epub 2019 Mar 7.

REMER, Clinical Electrophysiology, Neuroimaging and Neuromodulation Lab, Istanbul Medipol University, Istanbul, Turkey; Department of Biophysics, School of International Medicine, Istanbul Medipol University, Istanbul, Turkey.

Event-related oscillatory responses reflect the cognitive status in many neuropsychiatric conditions including mild cognitive impairment (MCI). In this study, a total of 30 patients with amnestic MCI (aMCI) and 25 patients with MCI of Parkinson's disease (PD-MCI) were compared with 28 aged-, gender-, education-matched healthy control (HC) participants using visual event-related delta, theta, alpha oscillatory responses by methods of event-related spectral perturbation and inter-trial coherence. PD-MCI and aMCI groups commonly share a decreased theta power, but all electrophysiological deviations from the controls were more prominent in PD-MCI than aMCI in all frequency bands. Read More

Mismatch negativity (MMN) reduction is one of the most robust findings among several neurophysiological and neurocognitive measures in patients with schizophrenia. MMN is a promising biomarker for schizophrenia because of the following properties: 1) its relationship with early psychosis, including clinical high-risk (CHR); 2) its relationship with the functional abilities of patients; and 3) its translatability into basic research using animal models. Specifically, the utility of the passive auditory oddball paradigm that does not require subjects to make behavioral responses enables identical physiological activities to be obtained from both experimental animals and patients.

The interhemispheric miscommunication theory of auditory verbal hallucinations in schizophrenia.

Int J Psychophysiol 2019 Feb 7. Epub 2019 Feb 7.

Centre for Psychiatry and Psychotherapy, Justus-Liebig-University, Giessen, Germany.

Auditory verbal hallucinations (AVH) are hallmark symptoms of schizophrenia and have been linked to abnormal activation, connectivity and integration within the auditory, language, and memory brain networks. The interhemispheric miscommunication theory of AVH is based on a steadily growing number of studies using a variety of modalities (EEG, fMRI, DTI) reporting that both altered integrity of the interhemispheric auditory pathways and disturbed functional gamma-band synchrony between right and left auditory cortices significantly contribute to abnormal auditory processing and the emergence of AVH. Moreover, initial studies using pharmacological EEG and H MR spectroscopy provided first insights into the underlying neurochemistry of AVH. Read More

Aging, effort, and stereotyping: The evidence for the moderating role of self-involvement.

Int J Psychophysiol 2019 Apr 30;138:1-10. Epub 2019 Jan 30.

School of Natural Sciences and Psychology, Liverpool John Moores University, Tom Reilly Building, Byrom Street, Liverpool L3 3AF, UK.

A study with young and older adults (N = 91) investigated the effect of self-involvement on stereotyping tendency and effort mobilization. We hypothesized that the impact of self-involvement varies as a function of age: increased self-involvement should lead older adults to engage in more effortful information processing and decreased stereotyping, whereas increased self-involvement should have no impact on effort mobilization and stereotyping tendency in young adults. Young and older adults read narratives under low and high-self-involvement conditions before performing a recognition test that measured their stereotyping tendency. Read More

Faculty of Human Sciences, Waseda University, 2-579-15 Mikajima, Tokorozawa, Saitama 359-1192, Japan.

Our own ongoing motor actions are perceived through sensory feedback pathways, and are integrated with neural processes to modulate further actions. This sensory feedback mechanism is known to contribute to the rehabilitation of impaired motor functions. Recent evidence also suggests that mindfulness meditation improves our awareness to sensation; therefore, enhancement of awareness to sensory feedback through mindfulness meditation training may have potential clinical applications.

Adults' facial reaction to affective facial expressions of children and adults.

Int J Psychophysiol 2019 May 26;139:33-39. Epub 2019 Jan 26.

Clinical Institute for Psychosomatic Medicine and Psychotherapy (15.16), Heinrich-Heine-University, Moorenstraße 5, 40225 Düsseldorf, Germany. Electronic address:

Facial mimicry, the unconscious imitation of others' affective facial expressions, serves as an important basis for interpersonal communication. Although there are many studies dealing with this phenomenon regarding the interaction between adults, only few experiments have explored facial mimicry in response to affective facial expressions of children. In the following study affect-prototypical video clips of children's and adults' faces were presented to 44 adults while the activity of corrugator supercilii and zygomaticus muscles was electromyographically measured.

Involuntary sensory enhancement of gain- and loss-associated tones: A general relevance principle.

Int J Psychophysiol 2019 Apr 25;138:11-26. Epub 2019 Jan 25.

Department of Psychology, Saarland University, Germany.

In a recent event-related potential (ERP) study (Folyi et al., 2016), we have demonstrated that sensory processing of task-irrelevant tones is enhanced when they were previously associated with positive or negative (by the means of monetary gains and losses, respectively) affective meaning relative to tones with neutral meaning, as indexed by the enhancement of the auditory N1-amplitude. In the present study, (1) in line with the hypothesis of affective counter-regulation, we investigated whether positive versus negative tones can receive differential attentional enhancement, depending on motivational context (Experiment 1); and (2) whether the early facilitation of positive and negative tones can operate strictly outside of the focus of voluntary attention (Experiment 2).

Personalizing neuromodulation.

Int J Psychophysiol 2019 Jan 24. Epub 2019 Jan 24.

Department of Psychology, Drexel University, Philadelphia, PA 19104, USA.

In the era of "big data", we are gaining rich person-specific information about neuroanatomy, neural function, and cognitive functions. However, the optimal ways to create precise approaches to optimize individuals' mental functions in health and disease are unclear. Multimodal analysis and modeling approaches can guide neuromodulation by combining anatomical networks, functional signal analysis, and cognitive neuroscience paradigms in single subjects. Read More

Mismatch negativity and cognitive performance in the course of schizophrenia.

Int J Psychophysiol 2019 Jan 23. Epub 2019 Jan 23.

Department of Psychology, PO Box 905, University of Konstanz, 78457 Konstanz, Germany. Electronic address:

Background: Cognitive deficits and abnormal event-related brain potentials (ERP) have been proposed as risk markers for the development of schizophrenia. Evidence is inconclusive whether these markers indicate a risk for the development of psychosis or illness progression.

Methods: The present study aimed at further clarification by comparing symptom expression (Brief Psychiatric Rating Scale, BRPS), the ERP Mismatch Negativity (MMN), and neuropsychological performance on the MATRICS Consensus Cognitive Battery between healthy controls (HC, n = 38) and individuals at different stages of illness: individuals at risk for psychosis (ARP, n = 33), patients at first admission, thus, early stage (ES, n = 35), chronic schizophrenia patients (CS, n = 25).

Visual presentation modality's superiority in the detection of concealed information: A comparison of the efficiencies of the P300-based Complex Trial Protocol in visual versus auditory modalities.

Int J Psychophysiol 2019 Mar 18;137:32-40. Epub 2019 Jan 18.

Department of Psychology, Faculty of Education, Hubei University, Wuhan, China.

Some studies have shown a superiority of visual vs. auditory item presentation in the Complex Trial Protocol (CTP), which is a countermeasure-resistant version of the P300-based Concealed Information Test (CIT). But those studies used elaborately- rehearsed autobiographical information as stimuli, instead of incidentally-acquired crime-related information. Read More

Exploring brain functions in autism spectrum disorder: A systematic review on functional near-infrared spectroscopy (fNIRS) studies.

Int J Psychophysiol 2019 Mar 19;137:41-53. Epub 2019 Jan 19.

Department of Experimental Clinical and Health Psychology, Ghent University, Henri Dunantlaan 2, 9000 Ghent, Belgium.

A growing body of research has investigated the functional development of the brain in autism spectrum disorder (ASD). Functional near-infrared spectroscopy (fNIRS) is increasingly being used in this respect. This method has several advantages over other functional neuroimaging techniques in studying brain functions in ASD, including portability, low cost, and availability in naturalistic settings.

Overprotective/authoritarian maternal parenting is associated with an enhanced error-related negativity (ERN) in emerging adult females.

Int J Psychophysiol 2019 Mar 4;137:12-20. Epub 2019 Jan 4.

Department of Psychology, McGill University, Montréal, Québec H3A 1G1, Canada. Electronic address:

Error monitoring is crucial for survival and adaptation, and can be indexed by the error-related negativity (ERN), a fronto-centrally located negative deflection in the event-related potential (ERP) waveform that differentiates erroneous from correct responses within 100 ms of a response. The ERN is seen as an early neural signal indicating the need to adjust performance and increase executive control. Previous findings indicate that punishing errors increases ERN magnitude, and that punitive parenting predicts an enhanced ERN in children. Read More

Efference copy/corollary discharge function and targeted cognitive training in patients with schizophrenia.

Int J Psychophysiol 2018 Dec 29. Epub 2018 Dec 29.

University of California at San Francisco, United States of America; San Francisco VA Healthcare System, United States of America. Electronic address:

Introduction: During vocalization, efference copy/corollary discharge mechanisms suppress the auditory cortical response to self-generated sounds as reflected in the N1 component of the auditory event-related potential (ERP). N1 suppression during talking is reduced in patients with schizophrenia. We hypothesized that these deficits would recover with auditory training that targets the speech processing system. Read More

Institute of Psychology, University of Bonn, Kaiser-Karl-Ring 9, 53111 Bonn, Germany.

Although the association of the N2 component with behavioral inhibition (BIS) has regularly been investigated, its association with other personality characteristics remains widely unknown. We investigated the association of the N2 with the sensitivity of the behavioral activation system (BAS). The aim was not to show that the N2 is linked to trait BAS instead of trait BIS, but that a motivating setting may alter its association with those traits. Read More

Abnormalities in early auditory information processing (EAIP) contribute to higher-order deficits in cognition and psychosocial functioning in schizophrenia. A passive auditory oddball paradigm is commonly used to evoke event-related potential (ERP) measures of EAIP reflecting auditory sensory registration and deviance detection, including mismatch negativity (MMN) and P3a responses. MMN and P3a have been extensively studied in healthy subjects and neuropsychiatric patient populations and are increasingly used as translational biomarkers in the development of novel therapeutics.

Resting heart rate variability, emotion regulation, psychological wellbeing and autism symptomatology in adults with and without autism.

Int J Psychophysiol 2019 Mar 19;137:54-62. Epub 2018 Dec 19.

Olga Tennison Autism Research Centre, School of Psychology and Public Health, La Trobe University, Bundoora, Victoria 3086, Australia; Stanford Autism Centre, Department of Psychiatry and Behavioral Sciences, Child and Adolescent Psychiatry, School of Medicine, Stanford University, United States of America.

Heart rate variability (HRV) has been separately shown to be associated with ASD symptomatology, psychological wellbeing and emotion regulation (ER) in specific samples consisting of either individuals with ASD, those without ASD, or combined. However, no study has examined these constructs together or incorporated habitual ER strategy use. Hence, the aim of this study was to examine the relationships between resting HRV, ASD symptomatology, ER strategy use (reappraisal and suppression), and psychological wellbeing (anxiety, depression and positive wellbeing) in a combined sample of adults with and without ASD.

Temporal dynamics of hedonic and eudaimonic reward processing: An event-related potentials (ERPs) study.

Int J Psychophysiol 2019 Mar 18;137:63-71. Epub 2018 Dec 18.

Shaanxi Key Laboratory of Behavior and Cognitive Neuroscience, School of Psychology, Shaanxi Normal University, Xi'an 710062, China. Electronic address:

Reward or pleasure can be achieved from a hedonic approach (pleasure attainment) or eudaimonic approach (meaning and self-realization). However, the neurodynamics of hedonic and eudaimonic reward processing remain unclear. By operationalizing hedonic reward as "win money for oneself" and eudaimonic reward as "win money for charity", the current study used the monetary incentive delay task to parse hedonic and eudaimonic reward dynamics into the anticipatory and consummatory stages while event-related potentials (ERPs) were recorded.

Genetic and environmental relations of executive functions to antisocial personality disorder symptoms and psychopathy.

Int J Psychophysiol 2018 Dec 18. Epub 2018 Dec 18.

Institute for Behavioral Genetics, University of Colorado Boulder, United States of America; Department of Psychology and Neuroscience, University of Colorado Boulder, United States of America.

Meta-analytic findings suggest that antisocial behavior, broadly defined, may relate to a Common Executive Function (EF) factor that captures covariance across response inhibition, working memory updating, and mental set shifting tasks. However, it is unclear whether this common factor, which is isomorphic with individual differences in response inhibition, accounts for all of the EF variance in antisocial behavior and psychopathy, or if they also relate to updating- and shifting-specific abilities. Moreover, findings that antisocial behavior and lower cognitive ability are particularly associated with the psychopathy dimension reflecting impulsivity and irresponsibility, compared to the dimension reflecting affective-interpersonal functioning, raise the possibility that EF relates to the variance shared between the impulsive-irresponsible psychopathy dimension and antisocial personality disorder.
