Selective attention depends on goal-directed and stimulus-driven modulatory factors, each relayed by different brain rhythms. Under certain circumstances, stress-related states can change the balance between factors. However, neuronal mechanisms underlying these changes remain unclear. In this study, we explored how psychosocial stress modulate rhythms during an attentional task a task-free period. We recorded EEG ECG activity of 42 healthy participants subjected to either Trier Social...
Abstract Attentional mechanisms have been studied mostly in specific sensory domains, such as auditory, visuospatial, or tactile modalities. In contrast, attention to internal interoceptive visceral targets has only recently begun be studied, despite its potential importance emotion, empathy, and self‐awareness. Here, we the effects of shifting heart using a cue‐target detection paradigm during continuous EEG recordings. Subjects were instructed count either series visual stimuli (visual...
Focusing one's attention by external guiding stimuli towards a specific area of the visual field produces systematical neural signatures. One most robust is change in topological distribution oscillatory alpha band activity across parieto-occipital cortices. In particular, decreases over contralateral and/or increases ipsilateral scalp sites, respect to side where was focused. This evidence comes mainly from experiments an explicit cue informs subjects focus their attention, thus...
Face-to-face communication has several sources of contextual information that enables language comprehension. This is used, for instance, to perceive mood interlocutors, clarifying ambiguous messages. However, these cues are absent in text-based communication. Emoticons have been proposed as used stress the emotional intentions on this channel Most studies suggested their role contribute a more accurate perception emotions. Nevertheless, it not clear if influence disambiguation independent...
Abstract Autonomous sensory meridian response (ASMR) describes the experience of a pleasant body sensation accompanied by feeling well‐being and relaxation in to specific audiovisual stimuli, such as whispers personal attention. Previous work suggests relationship between this with processing affective states; however, no research has explored differences interoception people experiencing ASMR those who do not. We hypothesized that is based on processing. To test this, we assessed group...
Autonomous Sensory Meridian Response (ASMR) describes the experience of a pleasant tingling sensation along back head, accompanied with feeling well-being and relaxation, in response to specific audio-visual stimuli, such as whispers, soft sounds, personal attention. Previous works have assessed individual variations personality traits associated ASMR, but no research date has explored differences emotion regulation ASMR. This omission occurred even when sensory-emotional experience, been...
Abstract Autonomous sensory meridian response (ASMR) and affective touch (AT) are two phenomena that have been independently investigated from separate lines of research. In this article, I provide a unified theoretical framework for understanding studying them as complementary processes. highlight their shared biological basis positive effects on emotional psychophysiological regulation. Drawing evolutionary developmental theories, propose ASMR results the development mechanisms associated...
Visual sensory processing of external events decreases when attention is internally oriented toward self-generated thoughts and also differences in attenuation have been shown depending on the thought's modality (visual or auditory thought). The present study aims to assess whether such modulations occurs modality. In order investigate modulations, we compared a passive listening condition with two conditions which was as part task; visual imagery an inner speech condition. EEG signal...
Autonomous Sensory Meridian Response (ASMR) is a multisensory experience most often associated with feelings of relaxation and altered consciousness, elicited by stimuli which include whispering, repetitive movements, close personal attention. Since 2015, ASMR research has grown rapidly, spanning disciplines from neuroscience to media studies but lacking collaborative or interdisciplinary approach. To build cohesive connected structure for moving forwards, modified Delphi study was conducted...
This article provides data from statistical analysis of event-related brain potentials (ERPs) and behavioural performance 23 participants during a working memory task. Specifically, we used the change detection task Vogel 2004, using same timing but modified size distance between stimuli. Contralateral delay activity (CDA) was calculated posterior parieto-occipital electrodes then it compared conditions with different load (one, two four items). Working capacity (WMC) formula developed by...
This article provides data from statistical analysis of event-related brain potentials (ERPs) and spectral power 20 participants during three attentional conditions. Specifically, P1, N1 P300 amplitude ERP were compared when participant׳s attention was oriented to an external task, a visual imagery inner speech. The alpha band also in these These are related the research where sensory processing information conditions entitled "Orienting or verbal/auditory differentially impairs stimuli"...
Abstract Acute psychosocial stress is associated with physiological, subjective and cognitive changes. In particular, attention, which considered one of the main processes driving cognition, has been related to different outcomes, such as anxiety, cortisol levels autonomic responses, individually. Nonetheless, their specific contributions association attention still not fully understood. To study this association, 42 male participants were asked perform an attentional task just before...
Abstract Emoticons have been considered pragmatic cues that enhance emotional expressivity during computer-mediated communication. Yet, it is unclear how emoticons are processed in ambiguous text-based communication due to incongruences between the emoticon's valence and its context. In this study, we investigated electrophysiological correlates of contextual influence on early processing emoticons, an congruence judgment task. Participants were instructed judge a text message expressing...
