Shared cognitive mechanisms of hypnotizability with executive functioning and information salience

Abstract

In recent years, evidence linked hypnotizability to the executive control and information salience networks, brain structures that play a role in cognitive conflict resolution and perseveration (insisting on applying a previously learned logical rule on a new set). Despite the growing body of neuroimaging evidence, the cognitive phenotype of hypnotizability is not well understood. We hypothesized that higher hypnotizability would correspond to lower perseveration and set-shifting. Seventy-two healthy adults were tested for hypnotizability and executive functions (perseveration and set-shifting). Multiple regression analyses were performed to test the relationship between hypnotizability and perseveration and set-shifting. Higher hypnotizability was associated with lower perseveration after accounting for age and education. Hypnotizability significantly predicted perseveration but not set-shifting. Our results indicate an inverse relationship between trait hypnotizability and perseveration, an executive function that utilizes regions of both the executive control and the salience systems. This suggests that hypnotizability may share a common cognitive mechanism with error evaluation and implementation of logical rules.

Can hypnotic susceptibility be explained by bifactor models? Structural equation modeling of the Harvard group scale of hypnotic susceptibility – Form A

“…Furthermore, in a large sample (𝑁 = 180), Dienes et al (2009) found no correlation between hypnotic-suggestibility and cognitive capabilities. The present study indicates why the findings of studies investigating the relation between hypnotic-suggestibility and cognitive control are inconclusive (e.g., Dienes et al, 2009;Faerman & Spiegel, 2021;Ludwig et al, 2013;Parris, 2017;Terhune et al, 2017). Studies investigating the relation between hypnotizability and other processes must take into account the bifactorial nature of the scales employed.…”

“…Executive functions. Hypnosis enhances executive functions such as those of inhibition, emotional control and mental flexibility [26][27][28]. Hypnotic suggestions engage individuals in new and adaptive patterns of thinking, feeling and behaving.…”

“…Faerman et al [26] provided evidence that the tendency to respond to hypnosis is linked to cognitive flexibility. The researchers selected 72 participants who firstly completed the Harvard Group Scale of Hypnotic Susceptibility and afterwards two neuropsychological tests that assess the cognitive phenomenon known as perseveration.…”
