Spatial regularities in a closed-loop audiovisual search task bias subsequent free-viewing behavior
Statistical learning of spatial regularities during visual search leads to prioritization of target-rich locations. The resulting attentional bias may subsequently affect orienting and search behavior in similar tasks but its transfer to free viewing has not been demonstrated.

Susceptibility to multitasking in stroke is associated to multiple-demand system damage and leads to lateralized visuospatial deficits
Cognitive impairment after stroke is heterogeneous: there is no strict correspondence between brain damage and magnitude of deficit or recovery. Protective factors such as cognitive or brain reserve have been invoked to explain the mismatch.

Catching Mind Wandering With Pupillometry: Conceptual and Methodological Challenges
Mind-wandering (MW) refers to the shift of attention away from an ongoing task and/or external environment towards mental contents (e.g., memories, prospective thoughts) unrelated to the task. 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.

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.

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.

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.

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.

Effects of attentional shifts along the vertical axis on number processing: An eye-tracking study with optokinetic stimulation
Previous studies suggest that associations between numbers and space are mediated by shifts of visuospatial attention along the horizontal axis. In this study, we investigated the effect of vertical shifts of overt attention, induced by optokinetic stimulation (OKS) and monitored through eye-tracking, in two tasks requiring explicit (number comparison) or implicit (parity judgment) processing of number magnitude.

Atomoxetine modulates the contribution of low-level signals during free viewing of natural images in rhesus monkeys
Visuo-spatial attentional orienting is fundamental to selectively process behaviorally relevant information, depending on both low-level visual attributes of stimuli in the environment and higher-level factors, such as goals, expectations and prior knowledge.

Close facial emotions enhance physiological responses and facilitate perceptual discrimination
Accumulating evidence indicates that the peripersonal space (PPS) constitutes a privileged area for efficient processing of proximal stimuli, allowing to flexibly adapt our behavior both to the physical and social environment.
