Can we measure mesopic pupil size with the cobalt blue light slit-lamp biomicroscopy method? [PDF]
, 2012 Producción CientíficaThe aim of this work is to assess a previously described slit-lamp biomicroscopy-based method (SLBM) for measuring pupil diameter and compare it to Colvard infrared pupillometry (CIP).

Give me a break! Unavoidable fatigue effects in cognitive pupillometry
Psychophysiology, 2023 Pupillometry has a rich history in the study of perception and cognition. One perennial challenge is that the magnitude of the task-evoked pupil response diminishes over the course of an experiment, a phenomenon we refer to as a fatigue effect.

Investigating the role of LC‐NA system activity in age differences in performance monitoring: insights from pupillometry [PDF]
Alzheimers DementAbstract Background Performance monitoring is pivotal for learning and decision‐making across the lifespan. While evidence suggests that these abilities decline with age and older individuals often tend to overestimate their abilities, that is, show imprecise metacognitive evaluations of their performance.

PupilEXT: Flexible Open-Source Platform for High-Resolution Pupillometry in Vision Research
Frontiers in Neuroscience, 2021 The human pupil behavior has gained increased attention due to the discovery of the intrinsically photosensitive retinal ganglion cells and the afferent pupil control path’s role as a biomarker for cognitive processes. Diameter changes in the range of 10–

First steps into the pupillometry multiverse of developmental science
Behavior Research Methods, 2023 Pupillometry has been widely implemented to investigate cognitive functioning since infancy. Like most psychophysiological and behavioral measures, it implies hierarchical levels of arbitrariness in preprocessing before statistical data analysis.

Listening to limericks: a pupillometry investigation of perceivers’ expectancy [PDF]
, 2013 What features of a poem make it captivating, and which cognitive mechanisms are sensitive to these features? We addressed these questions experimentally by measuring pupillary responses of 40 participants who listened to a series of Limericks.

The Costs of Paying Overt and Covert Attention Assessed With Pupillometry
Psychology Science, 2023 Attention can be shifted with or without an accompanying saccade (i.e., overtly or covertly, respectively). Thus far, it is unknown how cognitively costly these shifts are, yet such quantification is necessary to understand how and when attention is ...

Evaluation of autonomic involvement in Parkinson's disease using pupillometry. [PDF]
Neurol SciThe pupillary light reflex (PLR) indicates the function of the autonomic nervous system, which causes the pupil to constrict and dilate. Evaluation of the PLR determines the parasympathetic and sympathetic balance.
