Neural response to trauma-related and trauma-unrelated negative stimuli in remitted and persistent pediatric post-traumatic stress disorder.

Brain Behav 2021 Jun 2:e02173. Epub 2021 Jun 2.

Sixth Hospital/Institute of Mental Health, Peking University, Beijing, China.

Introduction: Most youths who suffer from post-traumatic stress disorder (PTSD) lose their diagnosis in the first 1-2 years. However, there are few studies on this brain mechanism, and the heterogeneity of the findings is partially due to the different stimuli applied and the mixed trauma history. Therefore, the use of trauma-related/unrelated stimuli to study the remittance mechanism of earthquake-induced PTSD could advance our knowledge of PTSD and inspire future treatment. Read More

Electroencephalography (EEG) Reveals Increased Frontal Activity in Social Presence.

Brain Sci 2021 May 31;11(6). Epub 2021 May 31.

Faculty of Psychology, Sigmund Freud University, Sigmund Freud Platz 1, 1020 Vienna, Austria.

It remains an unsolved conundrum how social presence affects the neural processes involved in adaptive situation-specific decision-making mechanisms. To investigate this question, brain potential changes via electroencephalography (EEG) and skin conductance responses (SCR) were taken within this study, while participants were exposed to pre-rated pleasant, neutral, and unpleasant pictures, which they had to rate in terms of their perceived arousal. Crucially, they had to-in respective runs-do this alone and in the presence of a significant other. Read More

Front Public Health 2021 14;9:638516. Epub 2021 May 14.

Department of Educational and Social Policy, University of Macedonia, Thessaloniki, Greece.

Young children are often unaware of emergency health conditions, such as stroke, and could serve as important vehicles to save the lives of their grandparents, who are more likely to suffer a stroke. An important aspect for the evaluation of public awareness on stroke signs and related emergency procedures is to examine the level of baseline stroke knowledge children have and whether they understand when to seek medical care on time. To examine the level of stroke symptomatology knowledge in children as well as evaluate their preparedness in stroke response before their participation in the educational program "FAST (Face, Arms, Speech, Time) 112 Heroes.

Threat imminence modulates neural gain in attention and motor relevant brain circuits in humans.

Psychophysiology 2021 May 24:e13849. Epub 2021 May 24.

Department of Experimental Psychology, Complutense University of Madrid, Madrid, Spain.

Different levels of threat imminence elicit distinct computational strategies reflecting how the organism interacts with its environment in order to guarantee survival. Thereby, parasympathetically driven orienting and inhibition of on-going behavior in post-encounter situations and defense reactions in circa-strike conditions associated with sympathetically driven action preparation are typically observed across species. Here, we show that healthy humans are characterized by markedly variable individual orienting or defense response tendencies as indexed by differential heart rate (HR) changes during the passive viewing of unpleasant pictures.

Automated emotion classification in the early stages of cortical processing: An MEG study.

Artif Intell Med 2021 May 31;115:102063. Epub 2021 Mar 31.

Biomagnetic Center, Jena University Hospital, 07747, Jena, Germany; Hans Berger Department of Neurology, Jena University Hospital, 07747, Jena, Germany. Electronic address:

Purpose: Here we aimed to automatically classify human emotion earlier than is typically attempted. There is increasing evidence that the human brain differentiates emotional categories within 100-300 ms after stimulus onset. Therefore, here we evaluate the possibility of automatically classifying human emotions within the first 300 ms after the stimulus and identify the time-interval of the highest classification performance.

Role of verbal working memory in rapid procedural acquisition of a choice response task.

Cognition 2021 May 13;214:104731. Epub 2021 May 13.

Psychology, College of Life and Environmental Sciences, University of Exeter, UK.

How quickly are instructions for a task translated into an effective task-set? If declarative working memory (dWM) is used to maintain a task's S-R rules until practice compiles them adequately into procedural memory, variables that affect retrieval from dWM should influence task performance while it is still dependent on dWM. Participants were trained on a series of 6-choice RT tasks, with a 1:1 mapping from object pictures to keys. In Experiments 1 and 2, an instruction phase - presentation of the S-R rules one by one -was followed by test trials. Read More

In exogenous attention, time is the clue: Brain and heart interactions to survive threatening stimuli.

PLoS One 2021 12;16(5):e0243117. Epub 2021 May 12.

Psychobiology Unit, Department of Psychology Rey Juan Carlos University, Madrid, Spain.

The capture of exogenous attention by negative stimuli has been interpreted as adaptive for survival in a diverse and changing environment. In the present paper, we investigate the neural responses towards two discrete negative emotions with different biological meanings, disgust and fear, and its potential relationships with heart rate variability (HRV) as an index of emotional regulation. With that aim, 30 participants performed a digit categorization task while fear, disgust and neutral distractor pictures were presented. Read More

The relationship between tendency to attend to detail, sensory sensitivity, and affective response to food cues - A registered report.

Int J Psychophysiol 2021 May 7;166:50-60. Epub 2021 May 7.

Abertay University, Dundee, Scotland, United Kingdom of Great Britain and Northern Ireland.

Understanding the underlying drivers of food choice remains a challenge and has highlighted the need for measures that capture data over and above that offered by self-reporting tools. Consequently, a growing body of research has set out to interpret facial responses to food cues to offer a greater insight into the emotional responses that may drive food acceptance. However, interpreting facial responses is challenging, as there are numerous factors that may influence affective response to foods, including expectation, context, and individual differences.

Increased early motivational response to food in adolescent anorexia nervosa revealed by magnetoencephalography.

Psychol Med 2021 May 5:1-9. Epub 2021 May 5.

Department of Child and Adolescent Psychiatry, University Hospital Muenster, Muenster, Germany.

Background: It remains unclear to what extent reduced nutritional intake in anorexia nervosa (AN) is a consequence of a reduced motivational response to food. Although self-reports typically suggest AN patients have a reduced appetitive response, behavioral and neurophysiological measures have revealed evidence for both increased and reduced attentional biases towards food stimuli. The mechanisms influencing food perception in AN, might be clarified using time-sensitive magnetoencephalography (MEG) to differentiate the early (more automatic processing) stages from the late (more controlled) stages.

Romantic love affects emotional processing of love-unrelated stimuli: An EEG/ERP study using a love induction task.

Brain Cogn 2021 Jul 26;151:105733. Epub 2021 Apr 26.

Department of General Psychology, University of Padova, Padova, Italy; Padova Neuroscience Center, University of Padova, Padova, Italy.

The aim of the present study was to investigate (a) the neural correlates of a love induction task (LIT) including listening to love-related songs and thinking about the romantic relationship, and (b) the effects of romantic love on the emotional processing of love-unrelated stimuli during a passive viewing task. The EEG was recorded in two groups of university students: people in love (Love Group, LG, N = 22, 19 F) and people not in love (Control Group, CG, N = 20, 15 F). The LIT induced higher pleasantness and arousal in the LG than in the CG, as well as higher alpha activity in occipital-right electrodes, suggesting active mental imagery and internal focused attention.

Interference effects of phonological similarity in word production arise from competitive incremental learning.

Cognition 2021 Jul 22;212:104738. Epub 2021 Apr 22.

School of Psychological Science, University of Bristol, United Kingdom.

In the blocked cyclic naming task, native Mandarin speakers named pictures with disyllabic names in small sets and blocks, with the critical manipulation whether pictures within a block shared an atonal syllable or not. We found the expected facilitation when the overlapping portion of responses was in word-initial position, but we also replicated a recent observation that with 'inconsistent' overlap (shared syllables could be either in first or second word position), form overlap causes interference. Crucially, interference also occurred when phonologically unrelated filler trials or trials which required a nonlinguistic response were interleaved with the critical pictures. Read More

Neural correlates of alcohol use disorder severity among nontreatment-seeking heavy drinkers: An examination of the incentive salience and negative emotionality domains of the alcohol and addiction research domain criteria.

Alcohol Clin Exp Res 2021 Apr 17. Epub 2021 Apr 17.

The Mind Research Network, Albuquerque, NM, USA.

Background: The Alcohol and Addiction Research Domain Criteria (AARDoC) propose that alcohol use disorder is associated with neural dysfunction in three primary domains: incentive salience, negative emotionality, and executive function. Prior studies in heavy drinking samples have examined brain activation changes associated with alcohol and negative affect cues, representing the incentive salience and negative emotionality domains, respectively. Yet studies examining such cue-induced changes in functional connectivity (FC) are relatively sparse. Read More
