Choosing in freedom or forced to choose? Introspective blindness to psychological forcing in stage-magic
(2013-03-13)We investigated an individual ability to identify whether choices were made freely or forced by external parameters. We capitalized on magical setups where the notion of psychological forcing constitutes a well trodden ... -
Chronotype at the beginning of secondary school and school timing are both associated with chronotype development during adolescence
(Scientific Reports, 2022)The misalignment between late chronotypes and early school start times affect health, performance and psychological well-being of adolescents. Here we test whether, and how, the baseline chronotype (i.e. chronotype at the ... -
Collective behavior in the spatial spreading of obesity
(2012-06-12)Obesity prevalence is increasing in many countries at alarming levels. A difficulty in the conception of policies to reverse these trends is the identification of the drivers behind the obesity epidemics. Here, we implement ... -
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 ... -
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 ... -
Delays without mistakes : response time and error distributions in dual-task
(2008-09-12)Background: When two tasks are presented within a short interval, a delay in the execution of the second task has been systematically observed. Psychological theorizing has argued that while sensory and motor operations ... -
Disentangling interoception : insights from focal strokes affecting the perception of external and internal milieus
(2015-05-01)Interoception is the moment-to-moment sensing of the physiological condition of the body. The multimodal sources of interoception can be classified into two different streams of afferents: an internal pathway of signals ... -
Diversity of opinions promotes herding in uncertain crowds
(Royal Society Open Science, 2022)Classic and recent studies demonstrate how we fall for the ‘tyranny of the majority' and conform to the dominant trend when uncertain. However, in many social interactions outside of the laboratory, there is rarely a clearly ... -
DUDF: Differentiable Unsigned Distance Fields with Hyperbolic Scaling
(Universidad Torcuato Di Tella, 2024)In recent years, there has been a growing interest in training Neural Networks to approximate Unsigned Distance Fields (UDFs) for representing open surfaces in the context of 3D reconstruction. However, UDFs are ... -
Dynamics of the central bottleneck : dual-task and task uncertainty
(2006-06-27)Why is the human brain fundamentally limited when attempting to execute two tasks at the same time or in close succession? Two classical paradigms, psychological refractory period (PRP) and task switching, have independently ... -
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 ... -
How do you feel when you can’t feel your body? Interoception, functional connectivity and emotional processing in depersonalization-derealization disorder
(2014-06-26)Depersonalization-Derealization Disorder (DD) typically manifests as a disruption of body self-awareness. Interoception 2 defined as the cognitive processing of body signals2 has been extensively considered as a key ... -
Imagetic and affective measures of memory reverberation diverge at sleep onset in association with theta rhythm
(Elsevier Inc, 2022)The ‘day residue’ - the presence of waking memories into dreams - is a century-old concept that remains controver- sial in neuroscience. Even at the psychological level, it remains unclear how waking imagery cedes into ... -
Interactive Crowdsourcing to Fact-check Politicians
(Journal of Experimental Psychology: Applied, 2023)The discourse of political leaders often contains false information that can misguide the public. Fact-checking agencies around the world try to reduce the negative influence of politicians by verifying their words. However, ... -
Learning normal asymmetry representations for homologous brain structures
(Universidad Torcuato Di Tella, 2023)Although normal homologous brain structures are approximately symmetrical by definition, they also have shape differences due to e.g. natural ageing. On the other hand, neurodegenerative conditions induce their own changes ... -
Neglect in human communication : quantifying the cost of cell-phone interruptions in face to face dialogs
(2015-06-03)There is a prevailing belief that interruptions using cellular phones during face to face inter- actions may affect severely how people relate and perceive each other. We set out to deter- mine this cost quantitatively ... -
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 ... -
Neural processing of emotional facial and semantic xxpressions in euthymic bipolar disorder (BD) and its association with theory of mind (ToM)
(2012-10-08)Background: Adults with bipolar disorder (BD) have cognitive impairments that affect face processing and social cognition. However, it remains unknown whether these deficits in euthymic BD have impaired brain markers of ... -
NORHA: A NORmal Hippocampal Asymmetry Deviation Index Based on One-Class Novelty Detection and 3D Shape Features
(Brain TopographySpringer, 2023)Radiologists routinely analyze hippocampal asymmetries in magnetic resonance (MR) images as a biomarker for neurodegenerative conditions like epilepsy and Alzheimer’s Disease. However, current clinical tools rely on either ... -
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 ...
