An examination of the moderating effects of neurophysiology on treatment outcomes from cognitive training in schizophrenia-spectrum disorders.

Int J Psychophysiol 2019 Feb 15. Epub 2019 Feb 15.

Department of Psychology, Queen's University, Kingston, Ontario, Canada; Centre for Addiction and Mental Health, Toronto, Ontario, Canada. Electronic address:

Background: Impairments in neurocognition and community functioning are core features of schizophrenia and cognitive training techniques have been developed with the aim of improving these impairments. While cognitive training has produced reliable improvements in neurocognition and functioning, little is known about factors that moderate treatment response. Electroencephalographic (EEG) measures provide a neurophysiological indicator of cognitive functions that may moderate treatment outcomes from cognitive training. Read More

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

Interoceptive accuracy, emotion recognition, and emotion regulation in preschool children.

Int J Psychophysiol 2019 Feb 4;138:47-56. Epub 2019 Feb 4.

Department of Clinical Child and Adolescent Psychology, University of Trier, Germany. Electronic address:

Little is known about the conscious experience of internal bodily sensations in preschool-aged children. Given that preschoolers are in the most rapid phase of brain development, and display profound emotional development, it was the aim of the present study to establish an adapted interoceptive accuracy paradigm and to investigate associations between sociodemographic (age, sex) and emotional variables with interoceptive accuracy. Forty-nine children (aged 4-6 years) completed the jumping jack paradigm (JJP), a heartbeat tracking paradigm, which includes a noninvasive physical perturbation via performing jumping jacks for 10 s.

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

Int J Psychophysiol 2019 Jan 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

Altered auditory feedback perception following an 8-week mindfulness meditation practice.

Int J Psychophysiol 2019 Jan 29;138:38-46. Epub 2019 Jan 29.

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 Jan 26. Epub 2019 Jan 26.

Clinical Institute for Psychosomatic Medicine and Psychotherapy (15.16), Heinrich-Heine-University, Moorenstraße 5, Geb, 15.16, 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 Jan 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).

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).

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.

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.

Resting gamma power during the postnatal critical period for GABAergic system development is modulated by infant diet and sex.

Int J Psychophysiol 2019 Jan 22;135:73-94. Epub 2018 Nov 22.

Arkansas Children's Nutrition Center, 15 Children's Way, Little Rock, AR 72202, USA; Department of Pediatrics, University of Arkansas for Medical Sciences, 4301 W. Markham St., Little Rock, AR 72205, USA.

Gamma band activity (30-50 Hz) plays an essential role in brain development and function, but neither the early postnatal development nor subject and environmental factors influencing this development have been reported. We documented the development of resting gamma power using high density EEG recordings obtained each month from postnatal month 2 to 6 in 518 healthy infants who were breast-fed (170; 85 boys), fed milk formula (186; 97 boys), or fed soy formula (162; 90 boys). Gamma power was determined for 44 sites distributed over major brain regions and analyses were adjusted for background variables relevant to neurodevelopment. Read More

Can we feel like being neither alert nor sleepy? The electroencephalographic signature of this subjective sub-state of wake state yields an accurate measure of objective sleepiness level.

Int J Psychophysiol 2019 Jan 22;135:33-43. Epub 2018 Nov 22.

Research Group for Math-Modeling of Biomedical Systems, The Research Institute for Molecular Biology and Biophysics of the Federal Research Center of Fundamental and Translational Medicine, Novosibirsk, Russia.

Accurate measurement of objective level of sleepiness can have important implications for experimental and field studies of sleep deprived individuals. We proposed to accurately quantify changes in sleepiness level with single electroencephalographic (EEG) measures obtained from EEG spectra consisting of 16 spectral powers within the frequency interval from 1 to 16 Hz. The EEG signal was recorded every other hour from 19:00 of Friday to 19:00 of Sunday in 48 study participants. Read More

Psychophysiology Laboratory, Institute of Psychology, Jagiellonian University, Krakow, Poland. Electronic address:

Previous research on auditory steady-state responses (ASSRs) demonstrated sensitivity of 40 Hz ASSR to changes in the level of arousal, both in sleep and in general anaesthesia. In this study we extended the range of stimulation frequencies, using also low and medium stimulation frequencies (4, 6, 8, 12, 20, 40 Hz) and studied their susceptibility to the loss of consciousness in NREM sleep (N2 and N3 stages). Effects of NREM sleep were examined in power domain with relative power (RP), and in phase domain using inter-trial phase coherence (PC) parameter. Read More

Influence of typicality in category-based fear generalization: Diverging evidence from the P2 and N400 effect.

Int J Psychophysiol 2019 Jan 14;135:12-20. Epub 2018 Nov 14.

College of Psychology and Sociology, Shenzhen University, Shenzhen, 518060, China; Shenzhen Key Laboratory of Affective and Social Cognitive Science, Shenzhen, 518060, China; Center for Language and Brain, Shenzhen Institute of Neuroscience, Shenzhen, 518057, China.

The conceptual properties of a conditional stimulus could contribute to human fear generalization, but how typicality influences fear generalization involving different conceptual hierarchies remains unclear. This study used event-related potential technology to investigate this in four categories of generalized stimulus (GS). We divided the GS into four categories: inferior typical members of conditioned stimulus (CS+) (TCS+), inferior atypical members of CS+ (ATCS+), inferior typical members of CS- (TCS-), and inferior atypical members of CS- (ATCS-).

Blink synchronization is an indicator of interest while viewing videos.

Int J Psychophysiol 2019 Jan 11;135:1-11. Epub 2018 Nov 11.

Graduate School of Information, Osaka University, Osaka, Japan.

The temporal pattern of spontaneous blinks changes greatly depending on an individual's internal cognitive state. For instance, when several individuals watch the same video, blinks can be synchronized at attentional breakpoints. The present study examined the degree of this blink synchronization, as reflecting an interest level, while viewing various video clips. Read More

Critical evaluation of current data analysis strategies for psychophysiological measures of fear conditioning and extinction in humans.

Int J Psychophysiol 2018 Dec 26;134:95-107. Epub 2018 Oct 26.

School of Psychological Sciences, University of Melbourne, Australia.

Fear conditioning and extinction is a construct integral to understanding trauma-, stress- and anxiety-related disorders. In the laboratory, associative learning paradigms that pair aversive with neutral stimuli are used as analogues to real-life fear learning. These studies use physiological indices, such as skin conductance, to sensitively measure rates and intensity of learning and extinction. Read More

Key Laboratory of Cognition and Personality of the Ministry of Education, Southwest University, Chongqing 400715, China. Electronic address:

The premise monotonicity effect during category-based induction is a robust effect that occurs when generalization of a novel property shared by many cases is more likely than one shared by few cases. The timing of brain activity during this effect is unclear. Therefore, the event-related potentials (ERPs) underpinning this effect were measured by manipulating the premise sample size (single [S] vs. Read More

Modulation of behavioral and brain responses to visual perspective taking by social rejection: Evidence from electrophysiology.

Int J Psychophysiol 2018 Dec 1;134:135-143. Epub 2018 Nov 1.

School of Biomedical Science and Medical Engineering, Southeast University, China; Research Center for Learning Science, Southeast University, China; Key Laboratory of Child Development and Learning Science (Ministry of Education), Southeast University, China; Institute of Child Development and Education, Southeast University, China.

Visual perspective taking (VPT) is crucial for reasoning about other people's mental states. To explore the modulation of behavioral and neural responses to visual perspective taking by social rejection, we firstly manipulated rejection using get-acquainted oral communication and a two-person visual perspective task, then explored how the experience of social rejection affected the behavioral and neural responses during the follow-up classical one-person visual perspective task. The subjective rating and behavior results showed that social rejection increased individuals' negative affect level and feelings of need-threat, decreased self-regulation and impulsive control.

The somatosensory mismatch negativity as a window into body representations in infancy.

Int J Psychophysiol 2018 Dec 30;134:144-150. Epub 2018 Oct 30.

Department of Psychology, Temple University, 1701 N. 13th Street, Philadelphia, PA 19122, USA.

How the body is represented in the developing brain is a topic of growing interest. The current study takes a novel approach to investigating neural body representations in infants by recording somatosensory mismatch negativity (sMMN) responses elicited by tactile stimulation of different body locations. Recent research in adults has suggested that sMMN amplitude may be influenced by the relative distance between representations of the stimulated body parts in somatosensory cortex. Read More

Insights into cognitive pupillometry: Evaluation of the utility of pupillary metrics for assessing cognitive load in normative and clinical samples.

Int J Psychophysiol 2018 Dec 17;134:62-78. Epub 2018 Oct 17.

Uniformed Services University of the Health Sciences, United States of America; Defense and Veterans Brain Injury Center, San Diego, CA, United States of America; Naval Medical Center San Diego, United States of America.

Despite increasing use of pupillometry to understand cognitive deficits in clinical populations, there is no consensus on what pupillary metrics are most useful. In this study, we compare the reliability, sensitivity to mild traumatic brain injury (TBI) and cognitive load differences, and the likelihood of replication between various pupillary metrics. Raw pupil diameter was recorded from 15 patients with chronic mild TBI and 23 uninjured controls while they performed a cognitive task with three levels of cognitive load. Read More

Human Psychobiology Lab, Experimental Psychology Department, University of Seville, C/Camilo José Cela s/n, 41018 Sevilla, Spain. Electronic address:

Global and local probability effects were explored in a visuo-auditory version of the central cue Posner's paradigm through the analysis of the neural Event-Related Potentials (ERPs) generated in the interaction between validity sequence effects (local probability) and block validity effects (global probability). Four behavioral measures (response times, correct/incorrect anticipations, and incorrect responses), three pre-target ERPs (visual P1/N1 and Contingent Negative Variation (CNV)), and six post-target ERPs (auditory N1, P2, Processing Negativity (PN), P3a, P3b and Late Slow Positivity (LSP)) were considered. Four types of trial-sequences (Valid-Valid, Invalid-Valid, Invalid-Invalid, Valid-Invalid) and three types of trial-blocks, with different validity/invalidity proportions (50%, 68%, and 86% of valid trials), were employed.

Blood pressure-related pain modulation in fibromyalgia: Differentiating between static versus dynamic pain indicators.

Int J Psychophysiol 2018 Dec 12;134:79-85. Epub 2018 Oct 12.

Department of Psychology, University of Jaén, Spain.

Introduction: Resting blood pressure (BP) has been found to be inversely associated with evoked pain responsiveness in healthy populations. However, some reports suggest that BP-related pain modulation may be dysfunctional in chronic pain patients. This study examined whether BP-related pain modulation, indexed by both static and dynamic evoked pain responses, is altered in fibromyalgia (FM) patients compared to pain-free individuals.

Cerebral blood flow is not modulated following acute aerobic exercise in preadolescent children.

Int J Psychophysiol 2018 Dec 12;134:44-51. Epub 2018 Oct 12.

Department of Psychological and Brain Sciences, University of Iowa, United States of America.

Cognitive enhancements following a single bout of exercise are frequently attributed to increases in cerebral blood flow, however to date we have little understanding of the extent to which such bouts of exercise actually even influence cerebral blood flow following the cessation of exercise. To gain such insight, both regional and global changes in cerebral blood flow were assessed using 3D pseudo-continuous arterial spin-labeled magnetic resonance imaging in a sample of 41 preadolescent children. Using a within-participants randomized crossover design, cerebral blood flow as assessed prior to and following 20-min of either aerobic exercise or an active-control condition during two separate, counterbalanced sessions.
