Key result
Log-transformed low frequency heart rate variability power during a creative task was significantly negatively correlated with the number of divergent thinking words generated (r = -0.47, p < 0.01).
Why the study?
Does a relaxed state before a creative task improve divergent thinking performance, and is psychophysiological state correlated with divergent thinking?

Lower LF-HRV during creative tasks was associated with better divergent thinking; extends autonomic-cognition links while leaving pre-task relaxation effects open.

Does a relaxed state before a creative task improve divergent thinking performance, and is psychophysiological state correlated with divergent thinking?
Effect estimate: r = -0.47
p-value: p=<0.01
A person's psychophysiological state, specifically lower LF HRV power, is correlated with better divergent thinking performance, though initial relaxation does not predict creative performance.
Loudon et al. (2016) conducted a cross-sectional in Healthy (assessing creativity) (n=50). Log-transformed low frequency heart rate variability (ln LF) vs. Unexposed/reference (correlation analysis across all participants) was evaluated on Number of divergent thinking words generated (r = -0.47, p=<0.01). Log-transformed low frequency heart rate variability power during a creative task was significantly negatively correlated with the number of divergent thinking words generated (r = -0.47, p < 0.01).
