Autonomic and cognitive control in memory: Investigating the psychophysiological link using heart rate variability biofeedback

“…Moreover, RMSSD was not linked to cognitive control over long-term memory. Contrary to this work, previous studies assessing cognitive control over long-term memory (Feeling et al, 2021;Gillie et al, 2014Gillie et al, , 2015Magnon et al, 2022) did not consider repeated measures over the same experimental session. An exploratory analysis (Data S8-SR3) revealed that the psychophysiological relationship changed over repeated measures due to baseline changes in cardiac control (i.e., mean heart rate and RMSSD).…”

“…Moreover, there is emerging evidence that vmHRV also relates to higher‐level cognitive function that is supported by cognitive control such as long‐term memory. In this line, it has been demonstrated that resting‐state vmHRV positively correlated to inhibitory control processes involved in the voluntary suppression of memory and thought (Gillie et al., 2014, 2015), memory discrimination between items with low visual distinctiveness (Magnon et al., 2022), and the reduction of false memories (Feeling et al., 2021). The present work will focus on the latter, as being able to distinguish between true and false long‐term memories is important for autonomy, self‐confidence, and the reliability of testimony (Devitt & Schacter, 2016; Loftus, 1996).…”
