A massive experiment on choice blindness in political decisions : confidence, confabulation, and unconscious detection of self-deception
(207-02-14)We implemented a Choice Blindness Paradigm containing political statements in Argentina to reveal the existence of categorical ranges of introspective reports, identified by confidence and agreement levels, separating ... -
Bridging psychology and mathematics : can the brain understand the brain?
(2004-09-14)We are told scientists are divided into experimentalists and theoreticians. The dialectic description of the dynamics of science, with one tribe gathering data and collecting evidence and another tribe providing form to ... -
Parsing a cognitive task : a characterization of the mind’s bottleneck
(2005-02-08)Parsing a mental operation into components, characterizing the parallel or serial nature of this flow, and understanding what each process ultimately contributes to response time are fundamental questions in cognitive ... -
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 ... -
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 ... -
The Spatial and Temporal Construction of Confidence in the Visual Scene
(2009-03-17)Human subjects can report many items of a cluttered field a few hundred milliseconds after stimulus presentation. This memory decays rapidly and after a second only 3 or 4 items can be stored in working memory. Here we ... -
The brain’s router : a cortical network model of serial processing in the primate brain
(2010-04-29)The human brain efficiently solves certain operations such as object recognition and categorization through a massively parallel network of dedicated processors. However, human cognition also relies on the ability to perform ... -
The neural basis of decision-making and reward processing in adults with euthymic bipolar disorder or attention-deficit/hyperactivity disorder (ADHD)
(2012-05-18)Background: Attention-deficit/hyperactivity disorder (ADHD) and bipolar disorder (BD) share DSM-IV criteria in adults and cause problems in decision-making. Nevertheless, no previous report has assessed a decision-making ... -
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 ... -
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 ... -
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 ... -
Organization of brain networks governed by long-range connections index autistic traits in the general population
(2013-06-27)Background: The dimensional approach to autism spectrum disorder (ASD) considers ASD as the extreme of a dimension traversing through the entire population. We explored the potential utility of electroencephalography (EEG) ... -
Attachment patterns trigger differential neural signature of emotional processing in adolescents
(2013-08-05)Background: Research suggests that individuals with different attachment patterns process social information differently, especially in terms of facial emotion recognition. However, few studies have explored social ... -
Vocal caricatures reveal signatures of speaker identity
(2013-12-03)What are the features that impersonators select to elicit a speaker’s identity? We built a voice database of public figures (targets) and imitations produced by professional impersonators. They produced one imitation ... -
Preliminary evidence about the effects of meditation on interoceptive sensitivity and social cognition
(2013-12-23)Background: Interoception refers to the conscious perception of body signals. Mindfulness is a meditation practice that encourages individuals to focus on their internal experiences such as bodily sensations, thoughts, ... -
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 ... -
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 ... -
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 ... -
Proprioceptive body illusions modulate the visual perception of reaching distance
(2015-06-25)The neurobiology of reaching has been extensively studied in human and non-human pri- mates. However, the mechanisms that allow a subject to decide—without engaging in explicit action—whether an object is reachable are not ...
