Loss of exercise- and stress-induced increases in circulating 2-arachidonoylglycerol concentrations in adults with chronic PTSD.

Biol Psychol 2019 Apr 9;145:1-7. Epub 2019 Apr 9.

Department of Kinesiology, University of Wisconsin-Madison, 2000 Observatory Dr., Madison, WI, 53706, USA.

The endocannabinoid (eCB) system is a modulatory system that is both altered by stress and mediates the effects of acute stress, including contributing to restoration of homeostasis. Earlier studies suggest that circulating eCBs are dysregulated in adults with post-traumatic stress disorder (PTSD); however, it is not known whether circulating eCBs remain responsive to stress. The purpose of this study was to examine eCB and psychological responses to physical (exercise) and psychosocial (Trier Social Stress Test) stressors, using a randomized, counterbalanced procedure in adults with PTSD and healthy controls (N = 20, mean age = 24, SD = 7 yrs).

Blunted neural response to appetitive images prospectively predicts symptoms of depression, and not anxiety, during the transition to university.

Biol Psychol 2019 Apr 8;145:31-41. Epub 2019 Apr 8.

2001 McGill College, Department of Psychology, McGill University, Montreal, Quebec, H3A 1G1, Canada. Electronic address:

Individual differences in neural response to appetitive and aversive stimuli may confer vulnerability to stress-related psychopathology, including depression and anxiety. However, the specificity of this association with symptoms of depression and anxiety within the context of real-world stress is not well understood. The present study examined whether neural responses to appetitive and aversive images, measured by the late positive potential (LPP), prospectively predict symptoms of depression and/or anxiety during the transition to university-a common, major life stressor-in 70 female emerging adults.

Confirmation Bias and Misconceptions: Pupillometric Evidence for a Confirmation Bias in Misconceptions Feedback.

Biol Psychol 2019 Apr 6. Epub 2019 Apr 6.

Department of Social Psychology, Tilburg University, Netherlands.

It has long been supposed that the confirmation bias plays a role in the prevalence and maintenance of misconceptions. However, this has been supported more by argument than by empirical evidence. In the present paper, we show how different types of belief-feedback evoke physiological responses consistent with the presence of a confirmation bias. Read More

Too many fish in the sea: A motivational examination of the choice overload experience.

Biol Psychol 2019 Apr 3;145:17-30. Epub 2019 Apr 3.

University at Buffalo, The State University of New York, Department of Psychology, Park Hall, Buffalo, NY 14260, United States.

Evidence supports that being overwhelmed by many choice options predicts negative consequences. However, there is uncertainty regarding the effects of choice overload on two key motivational dimensions: (1) the extent to which people view their decision as subjectively valuable (versus not), and (2) the extent to which people view themselves as capable (versus incapable) of reaching a good decision. While evaluating their options and while deciding, we assessed theory-based cardiovascular responses reflecting these dimensions. Read More

Socio-demographic predictors of prepulse inhibition: A prospective study in children and adolescents from Mexico City.

Biol Psychol 2019 Mar 30;145:8-16. Epub 2019 Mar 30.

Departments of Environmental Health and Epidemiology, Harvard T.H. Chan School of Public Health, Boston, MA, USA.

Prepulse inhibition (PPI) is a sensorimotor gating mechanism that reduces interfering influences to the neural processing of incoming stimuli, and is associated with several neurodevelopmental disorders. To date, research on PPI and neurodevelopmental disorders has primarily been in cross-sectional, clinical settings. In this prospective, epidemiologic study, we used a data-driven prediction model to identify socio-demographic predictors of PPI in children and adolescents from Mexico City to inform future etiologic studies evaluating PPI.

UR2NF - Neuropsychology and Functional Neuroimaging, CRCN - Centre de Recherches en Cognition et Neurosciences and UNI - ULB Neurosciences Institute, Université Libre de Bruxelles (ULB), Belgium. Electronic address:

Fatigue induced by sustained cognitive demands often entails decreased behavioural performance and the unavailability of brain resources, either due to reduced levels or impaired access. In the present study, we investigated the neural dynamics underlying preserved behavioural performance after inducing cognitive fatigue (CF) in a sleep deprivation (SD) condition in which resources are naturally compromised. Using functional near infrared spectroscopy (fNIRS), we recorded cortical brain activity during task-related CF induction in the evening, in the middle of the night and early in the morning.

Error-related brain activity in relation to psychopathic traits in multi-problem young adults: An ERP study.

Biol Psychol 2019 Mar 27;144:46-53. Epub 2019 Mar 27.

Department of Child and Adolescent Psychiatry, Amsterdam University Medical Center, Amsterdam, the Netherlands.

One of the most prominent issues in psychopathy is the inability to adequately monitor one's performance and learn from one's mistakes. We investigated the relationship between psychopathic traits, as measured with the Youth Psychopathy Inventory - Short Version, and both early and late error-related brain activity in an at-risk sample of male young adults. These multi-problem young adults (age 18-27) are severely dysfunctional in society and suffer from multiple problems including financial problems, delinquency, psychological problems, and drug use.

Hearing other's pain is associated with sensitivity to physical pain: an ERP study.

Biol Psychol 2019 Mar 23. Epub 2019 Mar 23.

College of Psychology and Sociology, Shenzhen University, Shenzhen, China. Electronic address:

Numerous studies have demonstrated an overlap between the processing of self-pain and others' pain, which suggests that psychological and neural representations are shared between the perception of physical pain and empathy for pain. As hearing emotional exclamations is a common way in which we regularly perceive and empathize with others' pain, the present study aimed to investigate the link between sensitivity to physical pain and the sounds made by others in pain. We recorded event-related potential (ERP) responses to another person's vocalizations (neutral or painful intonation) and identified electrophysiological responses associated with the processing of painful sounds.

School of Economics and Management, Shanghai University of Sport, Shanghai, China. Electronic address:

Although sports expertise has been shown to have transferable cognitive benefits, it is unclear how motor expertise influences brain activity during perceptual-cognitive tasks. The aim of the present study was to investigate whether improved perceptual-cognitive behavioral task performance in individuals with well-developed motor skills is associated with characteristic cortical activation and deactivation. Blood oxygenation-level dependent (BOLD) functional MRI (fMRI) was conducted in 23 athletes and 24 age- and education-matched non-athletes performing a multiple object tracking (MOT) task with graded levels of attentional load (two, three, or four targets).

Stimulus-driven attention and cognitive control during encoding: An event related brain potentials study.

Biol Psychol 2019 Mar 8;144:1-10. Epub 2019 Mar 8.

Michigan State University, United States.

Stimulus-driven attention drawn to relevant items can improve working memory (WM) whether attentional capture is driven by salient, low level features or by contingent salience from shared features with targets. In the current work, we examined the time course of enhanced attention to contingently salient information in a non-spatial WM task using event related brain potentials (ERPs). In line with previous work, we predicted that the encoding of contingently salient stimuli would be associated with an enhancement of cognitive control processes rather than low-level salience detection.

Marching to the beat of your own drum?: A proof-of-concept study assessing physiological linkage in Autism Spectrum Disorder.

Biol Psychol 2019 Mar 6;144:37-45. Epub 2019 Mar 6.

Department of Psychology, Virginia Polytechnic Institute and State University, United States; Virginia Tech Center for Autism Research, Virginia Polytechnic Institute and State University, United States.

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by difficulty in dynamically adjusting behavior to interact effectively with others, or social reciprocity. Synchronization of physiological responses between interacting partners, or physiological linkage (PL), is thought to provide a foundation for social reciprocity. In previous work we developed a new technique to measure PL using dynamic linear time series modeling to assess cardiac interbeat interval (IBI) linkage in typically developing same-sex unacquainted dyads (Scarpa et al.

Effect of the stop-signal modality on brain electrical activity associated with suppression of ongoing actions.

Biol Psychol 2019 Apr 23;143:85-92. Epub 2019 Feb 23.

Psychophysiology Lab, Faculty of Psychology, Universdad de Santiago de Compostela, Spain; Psychological Neuroscience Lab, Research Center in Psychology, School of Psychology, Universidade do Minho, Portugal.

To clarify how the modality of stop signals affects the ability to suppress ongoing actions, we compared behavioural indices and event-related potentials (ERPs) recorded in healthy volunteers performing visual and auditory stop-signal tasks. Auditory stop signals were associated with faster reaction times and shorter stop-N2 and stop-P3 latencies. Given that the tasks did not differ in attentional/arousal processes (go-P3 or stop-P3 amplitudes) or motor preparation (LRP amplitude, onset or latency), our results suggest that stop signal modality mainly affects bottom-up sensory processes (faster auditory processing).

Respiratory sinus arrhythmia (RSA) has been examined as a psychophysiological marker of stress vulnerability. Research indicates that low resting RSA is associated with physical and mental health problems, including posttraumatic stress disorder (PTSD). Some research suggests that people diagnosed with PTSD have lower RSA than people without PTSD, but findings have been mixed and the overall magnitude of this effect is unknown, indicating the need for a comprehensive meta-analysis.

Hospital Clínico San Carlos, Cibersam, Madrid, Spain.

Although response inhibition is thought to be important in borderline personality disorder (BPD), little is known about its neurophysiological basis. This study aimed to provide insight into this issue by capitalizaing on the high temporal resolution of electroencephalography and information provided by source localization methods. To this end, twenty unmedicated patients with BPD and 20 healthy control subjects performed a modified go/no-go task designed to better isolate the brain activity specifically associated with response inhibition.

Department of Psychological and Brain Sciences, University of Delaware, United States.

The present study used a longitudinal randomized clinical trial to test whether an early intervention has causal effects on children's autonomic nervous system regulation. When children were infants, parents involved with Child Protective Services received Attachment and Biobehavioral Catch-up (ABC; N = 43), an intervention that promotes sensitive parenting, or a control intervention (N = 53). When children were 9 years old, children whose parents had received ABC exhibited higher respiratory sinus arrhythmia and lower heart rate at rest and during a parent-child interaction than children in the control group.

Biol Psychol 2019 Apr 13;143:103-112. Epub 2019 Feb 13.

Intelligent Robotics Institute, School of Mechatronical Engineering, Beijing Institute of Technology, Beijing, China; Key Laboratory of Biomimetic Robots and Systems, Ministry of Education, Beijing, China.

Recent research has indicated that the mismatch negativity (MMN) is elicited in response to a discernible small change of a somatosensory stimulus applied on the hand. However, the neural mechanism for detecting small change of somatosensory stimulus remains unknown. In the present study, we developed a novel pressure stimulation device using air jet applied on the index finger pad, and determined the just noticeable differences (JNDs) of pressure discrimination for each subject.

Identification and transformation difficulty in problem solving: Electrophysiological evidence from chunk decomposition.

Biol Psychol 2019 Apr 11;143:10-21. Epub 2019 Feb 11.

Research Centre for Brain Function and Psychological Science, Shenzhen University, Shenzhen, China; Shenzhen Institute of Neuroscience, Shenzhen, China; Institute of Affective and Social Neuroscience, Shenzhen University, Shenzhen, China.

A wealth of studies have investigated how to overcome experience-based constraints in creative problem solving. One such experience-based constraint is the tendency for people to view tightly organized visual stimuli as single, unified percepts, even when decomposition of those stimuli into component parts (termed chunk decomposition) would facilitate problem solving. The current study investigates the neural underpinnings of chunk decomposition in creative problem solving by analyzing event-related potentials. Read More

Self-report and neurophysiological indicators of emotion processing and regulation in social anxiety disorder.

Biol Psychol 2019 Mar 8;142:126-131. Epub 2019 Feb 8.

Department of Psychiatry, University of Illinois at Chicago, Chicago, IL, United States; Department of Psychology, University of Illinois at Chicago, Chicago, IL, United States.

Individuals with social anxiety disorder (SAD) report less habitual reappraisal and more frequent suppression compared to healthy controls (HC). However, it is unclear whether a neurophysiological index of emotional reactivity, the late positive potential (LPP), is aberrant in SAD or whether self-reported reappraisal or suppression relates to the LPP during on-line emotion reactivity and reappraisal. Participants with SAD (n = 51) and HC (n = 31) completed an Emotion Regulation Task. Read More

Is your own face more than a highly familiar face?

Biol Psychol 2019 Mar 6;142:100-107. Epub 2019 Feb 6.

Departamento de Psicología Biológica y de la Salud, Facultad de Psicología, Universidad Autónoma de Madrid, Madrid, Spain. Electronic address:

This study aimed to elucidate whether distinct early processes underlie the perception of our own face. Alternatively, self-face perception might rely on the same processes that realize the perception of highly familiar faces. To this end, we recorded EEG activity while participants performed a facial recognition task in which they had to discriminate between their own face, a friend's face, and an unknown face. Read More

Eye-gaze contingent attention training (ECAT): Examining the causal role of attention regulation in reappraisal and rumination.

Biol Psychol 2019 Mar 5;142:116-125. Epub 2019 Feb 5.

Ghent University, Belgium.

This study used a novel eye-gaze contingent attention training (ECAT) to test the prediction that attention regulation is involved in reappraisal and rumination. Sixty-six undergraduates were randomly assigned to either the control or the active training condition of the ECAT. Active ECAT comprised training in allocating attention toward positive words to efficiently create positive interpretations while receiving gaze-contingent feedback. Read More

The importance of age in the search for ERP biomarkers of aMCI.

Biol Psychol 2019 Mar 2;142:108-115. Epub 2019 Feb 2.

Laboratorio de Neurociencia Cognitiva, Departamento de Psicoloxía Clínica e Psicobioloxía, Universidade de Santiago de Compostela, Galicia, Spain.

Alzheimer's Disease (AD) has become a major health issue in recent decades, and there is now growing interest in amnestic mild cognitive impairment (aMCI), an intermediate stage between healthy aging and dementia, usually AD. Event-related brain potential (ERP) studies have sometimes failed to detect differences between aMCI and control participants in the Go-P3 (or P3b, related to target classification processes in a variety of tasks) and NoGo-P3 (related to response inhibition processes, mainly in Go/NoGo tasks) ERP components. The aim of the present study was to evaluate whether the age factor, which is not usually taken into account in ERP studies, modulates group differences in these components. Read More

Cortisol reactivity and depressive symptoms in pregnancy: The moderating role of perceived social support and neuroticism.

Biol Psychol 2019 Jan 28. Epub 2019 Jan 28.

Department of Psychological Science, University of California, Irvine, 4562 Social and Behavioral Sciences Gateway, Irvine, CA 92697-7085, USA. Electronic address:

Perinatal depression negatively impacts mother-infant health and well-being. Previous work has linked cortisol reactivity to perinatal depressive symptoms, but moderating effects including social support and neuroticism, have not been studied. Forty-nine pregnant women (9-30 weeks' gestational age; GA) provided saliva samples in response to the Trier Social Stress Test (TSST) and to awakening (cortisol awakening response, CAR), and completed questionnaires on perceived social support, personality, and depressive symptoms.

Electro-cortical correlates of multisensory integration using ecologically valid emotional stimuli: Differential effects for fear and disgust.

Biol Psychol 2019 Mar 24;142:132-139. Epub 2019 Jan 24.

Department of Child and Adolescent Psychiatry, Psychotherapy, and Psychosomatics, Faculty of Medicine, University of Freiburg, Germany; Department of Psychiatry, National and Kapodistrian University of Athens, Medical School, Athens, Greece; Department of Child and Adolescent Psychiatry, Medical Faculty, University of Cologne, Germany. Electronic address:

Multisensory integration (MSI) is crucial for human communication and social interaction and has been investigated in healthy populations and neurodevelopmental disorders. However, the use of stimuli with high ecological validity is sparse, especially in event-related potential (ERP) studies. The present study examined the ERP correlates of MSI in healthy adults using short (500 ms) ecologically valid professional actor-produced emotions of fear or disgust as vocal exclamation or facial expression (unimodal conditions) or both (bimodal condition).

One plus one is more than two: The interactive influence of group membership and emotional facial expressions on the modulation of the affective startle reflex.

Biol Psychol 2019 Mar 21;142:140-146. Epub 2019 Jan 21.

Faculty of Behavioral Sciences, Department of Psychology, Saarland University, Building A2 4, D-66123 Saarbrücken, Germany. Electronic address:

It has been demonstrated repeatedly that the evaluation of a face is not only influenced by the social message that is signaled by the face's emotional expression, but also by other social factors such as ethnicity or group membership. Studies in the field of startle research, however, have hitherto investigated only the effects of one of the two factors - that is, either emotional expression or group membership - on the startle response. Yet, we propose that the startle reflex is a sensitive marker for the interactive effect of both factors. Read More

Department of Psychology, McGill University, 2001 McGill College Ave, Montreal, Quebec, H3A 1G1 Canada. Electronic address:

Unpredictability influences emotion and attention, but its effects on goal-directed behavior are unclear. We examined whether unpredictable events interfere with performance, using event-related potentials to specify underlying attentional dynamics. The paradigm involved task-irrelevant distracters of either predictable or unpredictable content (neutral/negative) preceding targets of a stimulus discrimination task. Read More

Children's sustained attention to emotional facial expressions and their autonomic nervous system reactivity during parent-child interactions.

Biol Psychol 2019 Mar 18;142:37-44. Epub 2019 Jan 18.

Center for Affective Science, Binghamton University (SUNY), United States.

The way individuals process socio-affective information is thought to impact their responses to social interactions, but research testing the relation between these processes is scarce, particularly among children. This study examined if children's attention to socio-affective stimuli was associated with their autonomic nervous system (ANS) reactivity during parent-child interactions. Children's sustained attention to facial expressions of emotion (afraid, happy, sad) was indexed using the late positive potential (LPP) event-related potential (ERP) component during a computer-based task.
