IIV PREDICTS PROSPECTIVE MEMORY FAILURES 2 AbstractThis study investigated the relationship between intraindividual variability (IIV) in reaction time and prospective memory errors in older adults using data from the Zurich Longitudinal

Associations between cardiorespiratory fitness, physical activity, intraindividual variability in behavior, and cingulate cortex in younger adults

“…A promising method for studying the relationships of MVPA and CRF to cognitive function is to use a measure of intraindividual variability (IIV) of response time (RT), which has been validated as an important metric of executive function 22 . Specifically, IIV in performance can be measured by examining trial-by-trial fluctuations in RT and reflects dynamic variability in attentional or executive control 23 . A growing body of evidence in older adults suggests that it is an important index of information processing efficiency, 24 a sensitive indicator of neurobiological integrity, 22 and a potential predictor of memory failures, 23 dementia, 25 and mortality 26 …”

Intraindividual Variability in Inhibition and Prospective Memory in Healthy Older Adults: Insights from Response Regularity and Rapidity

“…Loft and co-workers thus suggested that increased mean RT and variability reflect regular monitoring for the prospective target. In contrast, Haynes et al consistently found increased IIV in independent working memory and processing speed tasks to be predictive of lower performance on a composite PM score [63]. These authors speculated that the shared association between IIV and PM performance may arise from fluctuations in focus on the task and target monitoring.…”

Shifts in Audiovisual Processing in Healthy Aging

“…Furthermore, more recent work has also highlighted age-related increases in intra-individual variability on a number of these tasks [108-110]. Far from being epiphenomenal, changes in intra-individual variability may both precede and predict future cognitive declines, suggesting that this measure may represent an important predictive tool in the etiology of pathological aging [111-113]. It is currently unknown if intra-individual variability is domain general and observed across a wide range of sensory processing, or if it is more specific to certain kinds of sensory and multisensory processes.…”
