En el primer semestre de este curso impartí en la Universidad Loyola una asignatura de introducción a la estadística para la que tuve que preparar nuevo material docente basándome en libro “Statistics for the Behavioral Sciences” de Susan A. Nolan
Open Science round table at CIMCYC
Last Friday I participated in a round table discussing Open Science practices and their relevance for addressing the crisis of replicability in Psychology.
Jornadas de Ciencia Abierta en el CIMCYC
La semana pasada participé en una mesa redonda sobre las practicas de ciencia abierta y su importancia para enfrentar el problema de replicabilidad en Psicología.
How to upload your scientific software code to GitHub and get a DOI from Zenodo
This past weekend I had the pleasant experience of migrating my software KARDIA form its old home at the SourceForge repository to GitHub. Although the clearest benefit from this migration is the possibility to easier collaborate with other programers for the future development of the software, there are several other sweet candies that came along…
Can increased interoception explain exercise-induced benefits on brain function and cognitive performance?
This is the title of our new preprint, published in PsyArXiv, where we review the evidence in favor of the novel hypothesis that physical exercise enhances cognitive performance by improving interoception.
¿Qué es la Ciencia Abierta?
Muchos académicos todavía confunden Open Science con “Open Access” o, lo que es peor, creen que acceso abierto es sinónimo de publicar en revistas de acceso abierto. Este es el primero de una serie de posts en los que intentaré aclarar el significado y la relevancia del concepto de Open Science y explicar qué acciones sencillas podemos realizar los científicos para contribuir a generar una ciencia más abierta, transparente, eficiente y colaborativa. Empezaré ofreciendo mi visión personal sobre qué es la Ciencia, cuál debería ser su objetivo y cuál debería ser nuestra actitud para ayudar a que cumpla su función y contribuya a la sociedad de una forma más eficiente.
HEPLAB: Matlab scripts to facilitate heartbeat-evoked potential analysis
Last month my colleague Luis Ciria and I, gave a two-day workshop that focused on how to use the Matlab toolbox eeglab to create heartbeat-evoked events, extract epochs from the continuous EEG signal based on these events, and use Fieldtrip to perform a cluster-based permutation analysis to detect statistical differences between groups and conditions. The custom scripts we used at the workshop are freely available through the Zenodo repository.
Which side are you on boys?
As promised, I publish here a recent correspondence between Angel Correa, a colleague at the Brain, Mind & Behaviour Research Center of the University of Granada, and the editor of an Elsevier journal. I do not wish to express my opinion here —although the title and image of this post may be giving a hint— nor to reveal the identity of the editor. I prefer to listen to what my fellow colleagues think about which are the obligations and responsibilities of authors and journal editors in the emerging landscape of open scholarly communication.
Our preprint on brain-heart communication in athletes and sedentary young adults, available for peer review
Our recent research, revealing significant differences in how the brains of physically trained and sedentary young adults process information from the heart, is now available for commentary and formal peer review in two preprint repositories: SJS (@social_sjs) and bioRxiv (@biorxivpreprint).
How to detect the B point in impedance cardiography
Our new article, published in Psychophysiology and freely available from my Publications page, compares the accuracy of the three algorithms for B point detection included in Biopac’s popular software Acknowledge. We found unexpected and dramatic differences in the accuracy of these three algorithms, with the one based on the third derivative of the impedance cardiogram performing significantly better. In our article, we also provide a decision tree to help in the manual detection of the B point, especially by young and inexperienced researchers.
