Insomnia and Cognition: Mechanisms, Phenotypes, and Measurement

Insomnia is increasingly recognized not only as a disorder of sleep initiation or maintenance, but also as a condition closely tied to daytime cognitive and affective functioning, subjective cognitive complaints, emotional regulation, and broader cognitive-emotional processes. Research in this area spans multiple levels of analysis, including attention, executive functions, memory, cognitive arousal, metacognitive beliefs, and daytime functioning. At the same time, growing evidence suggests that insomnia is not a unitary phenomenon, but a heterogeneous condition that may be better understood through cognitive, behavioral, and psychological phenotypes. These developments make insomnia a particularly relevant field for work at the intersection of sleep research, cognitive psychology, and psychological measurement.Despite increasing interest in insomnia-related cognitive functioning, the literature remains fragmented across constructs, methods, and populations. Experimental studies, self-report approaches, neuropsychological assessments, and psychometric investigations often proceed in parallel, with limited integration. As a result, important questions remain open regarding which cognitive mechanisms are most relevant to insomnia, how subjective and objective cognitive functioning relate to one another, how heterogeneity should be conceptualized, and how best to measure these dimensions. This Research Topic aims to bring together contributions that clarify how insomnia relates to cognition from complementary perspectives and help build a more integrative and psychologically informed account of the condition. Recent advances in dimensional approaches, phenotype-oriented models, ecological and digital assessment, and psychometric methods make this a timely opportunity to consolidate the field and promote exchange across different research traditions.We welcome submissions addressing cognitive mechanisms involved in insomnia, cognitive consequences of insomnia symptoms, individual differences and phenotypes, and advances in assessment. Relevant themes include, but are not limited to:- cognitive mechanisms involved in insomnia, including attention, executive functions, memory, and cognitive arousal- subjective cognitive complaints and their relationship with objective cognitive performance- cognitive-emotional processes, including emotional regulation and metacognitive beliefs- insomnia phenotypes and individual differences from cognitive, behavioral, and psychological perspectives- dimensional and transdiagnostic approaches to insomnia and related daytime functioning- digital, ecological, and real-world assessment of insomnia-related cognitive functioning- psychometric evaluation and validation of insomnia-related measures- treatment-related cognitive change and its measurement across different intervention contextsWe welcome Original Research, Brief Research Reports, Reviews, Mini Reviews, Systematic Reviews and meta-analyses, Methods papers, and other theoretically relevant methodological contributions. Experimental, behavioral, clinical, psychometric, and neurophysiological approaches are all within scope when clearly embedded in a broader cognitive framework.
