In recent years, the fields of Audiology and Cognitive Sciences have seen a burgeoning of research focusing on the assessment of the effort required during listening. Among approaches to this question, the pupil dilation response has shown to be an informative nonvolitional indicator of cognitive processing during listening. Currently, pupillometry is applied in laboratories throughout the world to assess how listening effort is influenced by various relevant factors, such as hearing loss, signal processing algorithms, cochlear implant rehabilitation, cognitive abilities, language competency, and daily-life hearing disability. The aim of this special issue is to provide an overview of the state of the art in research applying pupillometry, guidance for those considering embarking on pupillometry studies, and to illustrate the diverse ways in which it can be used to answer—and raise—pertinent research questions.
