Automated analysis of free speech predicts psychosis onset in high-risk youths
(2015-08-26)BACKGROUND/OBJECTIVES: Psychiatry lacks the objective clinical tests routinely used in other specializations. Novel computerized methods to characterize complex behaviors such as speech could be used to identify and predict ... -
Quantitative pedagogy : a digital two player game to examine communicative competence
(2015-11-10)nner concepts are much richer than the words that describe them. Our general objective is to inquire what are the best procedures to communicate conceptual knowledge. We con- struct a simplified and controlled setup emulating ... -
Nudging cooperation in a crowd experiment
(2016-01-21)We examine the hypothesis that driven by a competition heuristic, people don't even reflect or consider whether a cooperation strategy may be better. As a paradigmatic example of this behavior we propose the zero-sum ... -
Confidence through consensus : a neural mechanism for uncertainty monitoring
(2016-02-24)Models that integrate sensory evidence to a threshold can explain task accuracy, response times and confidence, yet it is still unclear how confidence is encoded in the brain. Classic models assume that confidence is ... -
Neural markers of social and monetary rewards in children with attention-deficit/hyperactivity disorder and autism spectrum disorder
(2016-07-28)Recent theories of decision making propose a shared value-related brain mechanism for encoding monetary and social rewards. We tested this model in children with Attention-Deficit/Hyperactivity Disorder (ADHD), children ... -
Arithmetic on your phone : a large scale investigation of simple additions and multiplications
(2016-12-29)We present the results of a gamified mobile device arithmetic application which allowed us to collect vast amount of data in simple arithmetic operations. Our results confirm and replicate, on a large sample, six of the ... -
Producing or reproducing reasoning? Socratic dialog is very effective, but only for a few
(2017-03-23)Successful communication between a teacher and a student is at the core of pedagogy. A well known example of a pedagogical dialog is `Meno', a socratic lesson of geometry in which a student learns (or `discovers') how ... -
Dazzled by the mystery of mentalism : the cognitive neuroscience of mental athletes
(2017-05-31)Neural processing bymental athletes (MAs) has received attention fromNeuroscience community, with several publications examining superior memorizers (Maguire et al., 2003; Bor et al., 2008), lighting calculators (Pesenti ... -
Serial, parallel and hierarchical decision making in primates
(2017-06-26)he study of decision-making has mainly focused on isolated decisions where choices are associated with motor actions. However, problem-solving often involves considering a hierarchy of sub-decisions. In a recent study ... -
Attention, in and out : scalp-level and Intracranial EEG correlates of interoception and exteroception
(2017-07-19)Interoception, the monitoring of visceral signals, is often presumed to engage attentional mechanisms specifically devoted to inner bodily sensing. In fact, most standardized interoceptive tasks require directing attention ... -
Empathy for others’ suffering and its mediators in mental health professionals
(2017-07-25)Empathy is a complex cognitive and affective process that allows humans to experience concern for others, comprehend their emotions, and eventually help them. In addition to studies with healthy subjects and various ... -
A lesion model of envy and "Schadenfreude" : legal, deservingness and moral dimensions as revealed by neurodegeneration
(2017-08-21)The study of moral emotions (i.e. Schadenfreude and envy) is critical to understand the ecological complexity of everyday interactions between cognitive, affective, and social cognition processes. Most previous studies in ... -
An entropic barriers diffusion theory of decision-making in multiple alternative tasks
(2018-03-02)We present a theory of decision-making in the presence of multiple choices that departs from traditional approaches by explicitly incorporating entropic barriers in a stochastic search process. We analyze response time ... -
Social validation influences individuals’ judgments about ownership
(2018-06-30)In all domains, from informal to formal, there are conflicts about property and ownership which resolution demands consideration of alleged claims from more than one party. In this work we asked adults (N = 359) to judge ... -
Bayesian validation of grammar productions for the language of thought
(2018-07-10)Probabilistic proposals of Language of Thoughts (LoTs) can explain learning across differ- ent domains as statistical inference over a compositionally structured hypothesis space. While frameworks may differ on how a LoT ... -
Partisanship Predicts COVID-19 Vaccine Brand Preference: The Insightful Case of Argentina
(2022)The COVID-19 pandemic highlighted the importance of not only diminishing the resistance to vaccine adoption in general, but also to reduce both real and perceived barriers to a swift vaccination campaign. One major problem ... -
Peer tutoring of computer programming increases exploratory behavior in children
(Journal of Experimental Child Psychology, 2022)There is growing interest in teaching computer science and programming skills in schools. Here we investigated the efficacy of peer tutoring, which is known to be a useful educational resource in other domains but never ... -
The globalizability of temporal discounting
(Nature Human Behaviour, 2022)Economic inequality is associated with preferences for smaller, immediate gains over larger, delayed ones. Such temporal discounting may feed into rising global inequality, yet it is unclear whether it is a function of ... -
Working Memory for Spatial Sequences: Developmental and Evolutionary Factors in Encoding Ordinal and Relational Structures
(Journal of Neuroscience, 2022)Sequence learning is a ubiquitous facet of human and animal cognition. Here, using a common sequence reproduction task, we investigated whether and how the ordinal and relational structures linking consecutive elements ...
