Summary
Hypnotic susceptibility influences sensorimotor integration, affecting reflexes and posture. This cognitive trait impacts how individuals perceive and act, with implications for rehabilitation and adaptation.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Motor Control
Background:
- Hypnotizability is a cognitive trait linked to frontal executive system functions.
- It modulates behavioral and physiological processes, including sensorimotor integration.
- Differences in hypnotic susceptibility are associated with distinct neural characteristics.
Purpose of the Study:
- To review experimental findings on hypnotizability-related differences in sensorimotor integration.
- To explore interpretations based on morpho-functional considerations.
- To discuss the role of attention and imagery in postural control across hypnotic susceptibility levels.
Main Methods:
- Review of experimental results on sensorimotor integration and hypnotizability.
- Analysis of spinal motoneurone excitability differences.
- Examination of postural control in high and low hypnotic susceptibility groups.
Main Results:
- Hypnotizability affects spinal motoneurone excitability.
- Differences observed in reflex responses linked to prefrontal cortex projections and hemispheric balance.
- Postural control variations correlate with locus coeruleus and cerebellar activity.
Conclusions:
- Hypnotic susceptibility pervasively modulates perception-action integration.
- Findings suggest implications for neurorehabilitation and adaptation to altered environments.
- Attention and imagery play key roles in maintaining stability under altered sensory and cognitive demands.

01:28Perception
Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...

01:37Reason and Intuition
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the brain can only use...
01:15Subconsciousness and No Awareness
The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.
An illustrative example of subconscious processing is its role in problem-solving. Often, individuals...

01:15Subliminal Perception
Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...
01:19High-Level and Low-Level Awareness
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...
01:14Gestalt Psychology
Gestalt psychology, founded by Max Wertheimer, Kurt Koffka, and Wolfgang Kohler, emphasizes the importance of understanding perception as an organized whole. Developed as a counter to Wilhelm Wundt's structuralism, this approach posits that our perceptions are more than just the sum of sensory parts; they are comprehensive wholes where the relationships between parts define the perception. The principle "The whole is greater than the sum of its parts" encapsulates this view, illustrating how...
