In our recently published paper we investigate whether cardiovascular fitness or the type of sport activity practiced is more important for improving alertness. Read the post for a non-technical description of the results and their importance.
Replicability crisis in Psychology: causes and solutions
Summary and slides from the talk I gave on June 13th at the Psychology department of the University of Seville.
My teaching material for an undergraduate course in statistics using JASP available at OSF
I have used the OSF platform to publish my teaching material (in Spanish) for the undergraduate course in statistics I gave this year at the Loyola University. The material was based on the book “Statistics for the Behavioral Sciences” by
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.
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.
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.
