The presence of irrelevant alternatives paradoxically increases confidence in perceptual decisions
(Cognition, 2023)
Confidence in perceptual decisions is thought to reflect the probability of being correct.
According to this view, confidence should be unaffected or minimally reduced by the
presence of irrelevant alternatives. To test ...
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 ...
A better alignment between chronotype and school timing is associated with lower grade retention in adolescents
(NPJ Science of Learning, 2023)
Schools start early in the morning all over the world, contrasting with adolescents’ late chronotype. Interestingly, lower academic
performance (i.e. grades or qualifications) was associated with later chronotypes. However, ...
A synthesis of evidence for policy from behavioural science during COVID-19
(Nature ISSN 1476-4687 (online), 2023)
Scientific evidence regularly guides policy decisions1, with behavioural science increasingly part of this process2. In April 2020, an influential paper3 proposed 19 policy recommendations (‘claims’) detailing how evidence ...
VesselVAE: Recursive Variational Autoencoders for 3D Blood Vessel Synthesis
(Universidad Torcuato Di Tella, 2023)
We present a data-driven generative framework for synthesizing blood vessel 3D geometry. This is a challenging task due to the
complexity of vascular systems, which are highly variating in shape, size,
and structure. ...
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 ...
The wisdom of extremized crowds: Promoting erroneous divergent opinions increases collective accuracy
(Universidad Torcuato Di Tella, 2023)
The aggregation of many lay judgements can generate surprisingly accurate estimates. This effect, known
as the “wisdom of the crowd”, has been demonstrated in domains such as medical decision-making, factchecking
news, ...
Attraction by ingroup coherence drives the emergence of ideological sorting
(2023)
The increasing political polarization is driving hatred and segregation, and these pose a threat to democracy. While disagreement on policy issues is increasing and receiving great attention, people are also becoming more ...
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, ...
Partisanship predicts COVID-19 vaccine brand preference: the case of Argentina
(Humanities and Social Sciences Communications (Humanit Soc Sci Commun) ISSN 2662-9992 (online), 2023)
The COVID-19 pandemic underscored the significance of overcoming vaccine adoption
resistance and addressing real and perceived barriers for efficient vaccination campaigns.
One major problem faced by health systems around ...
