The role of autosuggestion in geriatric patients’ quality of life: a study on psycho-neuro-endocrine-immunology pathway

How the inner repetition of a desired perception changes actual tactile perception

Autosuggestion is a cognitive process where the inner repetition of a thought actively influences one's own perceptual state. In spite of its potential benefits for medical interventions, this technique has gained little scientific attention so far. Here, we took advantage of the known link between intensity and frequency perception in touch ('Békésy effect'). In three separate experiments, participants were asked to modulate the perceived intensity of vibrotactile stimuli at the fingertip through the inner reiteration of the thought that this perception feels very strong (Experiment 1, n = 19) or very weak (Experiments 2, n = 38, and 3, n = 20), while they were asked to report the perceived frequency. We show that the task to change the perceived intensity of a tactile stimulus via the inner reiteration of a thought modulates tactile frequency perception. This constitutes the first experimental demonstration that an experimental design that triggers autosuggestion alters participants' tactile perception using a response orthogonal to the suggested variable. We discuss whether this cognitive process could be used to influence the perception of pain in a clinical context.

Is hypnotic assessment relevant to neurology?

Studies conducted in healthy subjects have clearly shown that different hypnotic susceptibility, which is measured by scales, is associated with different functional equivalence between imagery and perception/action (FE), cortical excitability, and information processing. Of note, physiological differences among individuals with high (highs), medium (mediums), and low hypnotizability scores (lows) have been observed in the ordinary state of consciousness, thus independently from the induction of the hypnotic state, and in the absence of specific suggestions. The potential role of hypnotic assessment and its relevance to neurological diseases have not been fully explored. While current knowledge and therapies allow a better survival rate, there is a constant need to optimize rehabilitation treatments and quality of life. The aim of this paper is to provide an overview of hypnotizability-related features and, specifically, to discuss the hypothesis that the stronger FE, the different mode of information processing, and the greater proneness to control pain and the activity of the immune system observed in individuals with medium-to-high hypnotizability scores have potential applications to neurology. Current evidence of the outcome of treatments based on hypnotic induction and suggestions administration is not consistent, mainly owing to the small sample size in clinical trials and inadequate control groups. We propose that hypnotic assessment may be feasible in clinical routine and give additional cues into the treatment and rehabilitation of neurological diseases.

Autosuggestion: a cognitive process that empowers your brain?

Autosuggestion is a cognitive process that is believed to enable control over one’s own cognitive and physiological states. Despite its potential importance for basic science and clinical applications, such as in rehabilitation, stress reduction, or pain therapy, the neurocognitive mechanisms and psychological concepts that underlie autosuggestion are poorly defined. Here, by reviewing empirical data on autosuggestion and related phenomena such as mental imagery, mental simulation, and suggestion, we offer a neurocognitive concept of autosuggestion. We argue that autosuggestion is characterized by three major factors: reinstantiation, reiteration, and volitional, active control over one’s own physiological states. We also propose that autosuggestion might involve the ‘overwriting’ of existing predictions or brain states that expect the most common (but not desired) outcome. We discuss potential experimental paradigms that could be used to study autosuggestion in the future, and discuss the strengths and weaknesses of current evidence. This review provides a first overview on how to define, experimentally induce, and study autosuggestion, which may facilitate its use in basic science and clinical practice.

Nurses' psychological changes and coping strategies during home isolation for the 2019 novel coronavirus in China: A qualitative study

AIMS

To explore the psychological changes of nurses during home isolation, the factors that related with these changes, and coping strategies in home isolation during the epidemic of COVID-19 in China.

DESIGN

A qualitative study based on grounded theory.

METHODS

Individual semi-structured telephone interviews were conducted from January 2020-February 2020 with 10 nurses who were isolated at home sharing the experiences of the epidemic of COVID-19. All interviews were audio recorded, transcribed, and analysed using constant comparative data analysis.

RESULTS

Analyses of the collected data reveal that the psychological changes of nurses during home isolation reflect a complex, dynamic, and gradually adaptive process that was affected by many factors. Nurses had many negative emotional reactions in the early stages of isolation and positive emotions gradually increased during home isolation. After release from home isolation, they become more confident and calm after. Six categories of coping strategies were identified, including reasoned cognition; autosuggestion; develop healthy protective behaviours; shifting attention; social support; and the power of a role model.

CONCLUSIONS

The study provides a better understanding of the psychological changes and the coping strategies used among nurses isolated at home. It is necessary to pay more attention to negative emotions in the early stages of home isolation to help nurses adjust quickly. The coping strategies used by nurses are likely to help those in home isolation reduce negative psychological changes and experience more optimal self-adjustment.

IMPACT

This study explored the psychological changes and coping strategies of home isolation among nurses, providing useful advice for psychologists to develop psychological crisis interventions to help individuals reduce negative psychological and have more actively coping strategies when faced sudden stressful infectious diseases.
