Pupillary manifolds: uncovering the latent geometrical structures behind phasic changes in pupil size. We show that phasic changes in pupil size are inherently low-dimensional: they can be reconducted to a latent manifold that efficiently represents autonomic balance. Elvio A.

Pupillometry as a biomarker of Mind-Wandering (MW): a review We review the studies that used pupillometry as a biomarker for mind-wandering (MW), highlight the key challenges encountered, and provide recommendations for future research.

Phasic changes in pupil size are strikingly low-dimensional! In a new preprint, we show that very different tasks and processes map onto a very similar, low-dimensional latent space. We suggest that phasic changes in pupil size originate from a set of distinctive fingerprints that describe a pupillary manifold: a latent space that is highly constrained by the underlying physiological structures, i.e. the balance between different branches of the ANS.

Can pupil size detect signatures of math anxiety in young adults? In a new preprint we attempt to respond to the question. In short: math anxiety and low math performance are deeply ingrained in young adults, which makes it hard to disentangle these two aspects. Pupillometry does show, however, that cognitive effort is prolonged, rather than accentuated, in young adults with high levels of test (i.e., performance) anxiety. Elvio A.

Physiological measures (e.g., pupil size, EEG, and fMRI) have often been acquired as objective markers for MW states, which has greatly helped their study as well as triangulation with other measures. Claudia Pelagatti, Elvio A. Blini, Manila Vannucci PDF Cite Project DOI Pupil size as a biomarker of cognitive (dys)functions: Toward a physiologically informed screening of mental states The objective assessment of cognitive processes is of critical importance to understanding the mechanisms underlying various mental functions and dysfunctions. In recent years, the technological innovations related to the eye-tracking industry made the time right to organically integrate pupillometry in the assessment of cognitive profiles. Serena Castellotti, Elisa Castaldi, Elvio A. Blini, Roberto Arrighi PDF Cite Project DOI Pupillary manifolds: uncovering the latent geometrical structures behind phasic changes in pupil size Abstract The size of the pupils reflects directly the balance of different branches of the autonomic nervous system. This measure is inexpensive, non-invasive, and has provided invaluable insights on a wide range of mental processes, from attention to emotion and executive functions. Elvio A. Blini, Roberto Arrighi, Giovanni Anobile PDF Cite Project DOI What pupil size can and cannot tell about math anxiety Math Anxiety (MA) consists of excessive fear and worry about math-related situations. It represents a major barrier to numerical competence and the pursuit of STEM careers. Yet, we currently do not dispose of many tools that can capture its multifaceted nature, e. Elvio A. Blini, Giovanni Anobile, Roberto Arrighi PDF Cite Project DOI Pupil size as a robust marker of attentional bias toward nicotine-related stimuli in smokers Spatial attention can be magnetically attracted by behaviorally salient stimuli. This phenomenon occasionally conflicts with behavioral goals, leading to maladaptive consequences, as in the case of addiction, in which attentional biases have been described and linked with clinically meaningful variables, such as craving level or dependence intensity.
