The COVIDiSTRESS global survey collects data on early human responses to the 2020 COVID-19 pandemic from 173 429 respondents in 48 countries. open science study was co-designed by an international consortium of researchers investigate how psychological differ across countries and cultures, this has impacted behaviour, coping trust government efforts slow spread virus. Starting March 2020, leveraged convenience unpaid online recruitment generate public data. objective present analysis is...
Abstract This N = 173,426 social science dataset was collected through the collaborative COVIDiSTRESS Global Survey – an open effort to improve understanding of human experiences 2020 COVID-19 pandemic between 30th March and May, 2020. The allows a cross-cultural study psychological behavioural responses Coronavirus associated government measures like cancellation public functions stay at home orders implemented in many countries. contains demographic background variables as well Asian...
Abstract Background Vaccine hesitancy is driven by a heterogeneous and changing set of psychological, social historical phenomena, requiring multidisciplinary approaches to its study intervention. Past research has brought light instances both interpersonal institutional trust playing an important role in vaccine uptake. However, no comprehensive date specifically assessed the relative importance these two categories as they relate behaviors attitudes. Methods In this paper, we examine...
Learned Categorical Perception (CP) occurs when the members of different categories come to look more dissimilar (between-category separation) and/or same category similar (within-category compression) after a new has been learned. To measure learned CP and its physiological correlates we compared dissimilarity judgments Event Related Potentials (ERPs) before learning sort multi-featured visual textures into two by trial error with corrective feedback. With number trials feedback, about half...
Abstract Face masks obscure a significant portion of the face, reducing amount information available to gauge mental states others—that is, exercise Theory Mind (ToM) capacity. In three experiments, we assessed effect face on ToM judgements, measuring recognition accuracy, perceived valence, and arousal in various sets facial expressions comprising 45 different states. Significant effects were found all variables. Judgements are less accurate when masked, but, while judgements negative do...
The current study describes the case of a woman with symptomatic epilepsy due to brain cysticercosis acquired during childhood. During her adolescence, she developed seizures characterized by metamorphopsia, hallucinations autobiographic memory and, finally, asomatognosia. Magnetic imaging showed calcified lesion in right occipitotemporal cortex, and positron emission tomography confirmed presence interictal hypometabolism two regions: parietal cortex lateral posterior temporal cortex. We...
Vaccine hesitancy remains a significant and evolving public health challenge. The COVID-19 pandemic has created unique decision context with uncertainty caused by the novelty of disease being targeted, unfamiliarity vaccines offered, misinformation, strong handed government measures. In an effort to extend our understanding vaccine high environment presented COVID-19, we present novel taxonomy determinants hesitancy, based on inductive analysis qualitative data gathered during pandemic. We...
Learning to categorize requires distinguishing category members from non-members by detecting the features that covary with membership. Human subjects were trained sort visual textures into two categories trial and error corrective feedback. Difficulty levels increased decreasing proportion of covariant features. Pairwise similarity judgments tested before after learning. Three effects observed: (1) The lower features, more trials it took learn fewer who succeeded in learning it. After...
In human cognition, the expansion of perceived between-category distances and compression within-category is known as categorical perception (CP). There are several hypotheses about causes CP (e.g., language, learning, evolution) but no functional model. Whether essential to categorisation or simply a by-product it not yet clear, evidence accumulating that can be induced by category learning. We provide model for learning-induced in hidden-unit space neural nets. Basic conditions from which...
The COVID-19 pandemic brought about unique challenges, leading to a simultaneous decline in global mental well-being and an increase perceived social threats. present study explores the interplay between beliefs health symptoms multinational sample of 1500 individuals primarily from Canada, US Mexico.

Learned Categorical Perception (CP) occurs when the members of different categories come to look more dissimilar (“between-category separation”) and/or same category similar (“within-category compression”) after a new has been learned. To measure learned CP and its physiological correlates we compared dissimilarity judgments Event Related Potentials (ERPs) before learning sort multi-featured visual textures into two by trial error with corrective feedback. With number training trials...
Face masks obscure a significant portion of the face, reducing amount information available to gauge mental states others—that is, exercise Theory Mind (ToM) capacity. In two experiments, we assessed effect face on ToM judgements, measuring recognition accuracy, perceived valence, and arousal set facial expressions corresponding 45 different states. Significant effects were found in all three variables, with differential for positive negative states: Judgements are less accurate when masked,...
Through a series of black marks on sheet paper or screen, literature manages to build entire universes: transport us other times, show unknown places, introduce characters with whom we will never interact in real life; make live adventures and suffer tragedies and, all while sitting alone, share the feelings mental states others. How is this possible? What happens our brains bodies when read book? Reading fiction activates very diverse neural networks, from classic circuits language...
The link between language processing and motor systems has been the focus of increasing interest to Cognitive Neuroscience. Some classical papers studying Event Related Potentials (ERPs) induced by linguistic stimuli have found differences in electrophysiological activity when comparing action non-action words; more specifically, a bigger p200 for words. On other hand, series studies validated use grip force sensor (GFS) measure language-induced during both isolated words sentence listening,...
