Autocorrelation windows

Older age decreases autocorrelation windows in humans (Cohen's d -0.33 to -0.48, p < 0.01).

“Older adults demonstrated consistently shorter ACWs than younger adults (Cohen’s d range: -0.33 to -0.48, all p < 0.01), indicating decreased temporal continuity in neural activity with age.”
