OBJECTIVE This study was designed to determine whether hypnosis can modulate color perception. Such evidence would provide insight into the nature of hypnosis and its underlying mechanisms. METHOD Eight highly hypnotizable subjects were asked to see a color pattern in color, a similar gray-scale pattern in color, the color pattern as gray scale, and the gray-scale pattern as gray scale during positron emission tomography scanning by means of [(15)O]CO(2). The classic color area in the…

A suggestion for hypnotic color blindness was investigated by administering a reverse Stroop color-naming task and patterns are discussed in terms of potential cognitive and social mechanisms that may mediate responses to hypnoticcolor blindness.

The Power of mind: Blocking visual perception by hypnosis

It is concluded that the suggestion of the blockade affects later stages of visual perception, leaving early processes intact, and this illustrates the impact of suggestions and the power of mind.

Hypnotic visual hallucination induces greater lateralised brain activity than visual imagery

It is found that hypnotic hallucination of faces involves greater top-down activation of sensory processing through lateralised mechanisms in the right hemisphere compared to mental imagery, and the neural signatures that distinguish hypnotically hallucinated faces from imagined faces lie in theright brain hemisphere.

Neural correlates of induced grapheme-color synesthesia

The study yielded proof for hypnotically induced trance being an altered state of consciousness with significant changes in neural activity, and some conclusions on neural correlates of hypnotic suggestion are derived, which are however not as clear as the evidence for the altered state.

Posthypnotic Suggestion Alters Conscious Color Perception in an Automatic Manner

It is suggested that hypnosis can affect even a highly automatic process such as color perception, as a posthypnotic suggestion to see a brief, masked target as gray can change the color experience of a hypnotic virtuoso.



Functional neuroanatomy of hypnotic state

Cerebral Mechanisms of Hypnotic Induction and Suggestion

Results support a state theory of hypnosis in which occipital increases in rCBF and delta activity reflect the alteration of consciousness associated with decreased arousal and possible facilitation of visual imagery.

Relateralizing hypnosis: or, have we been barking up the wrong hemisphere?

A left-hemisphere theory of hypnosis is discussed in light of recent findings and theories about a left- Hemispheric basis for synthetic or generational capabilities and a neuro-evolutionary model of a left -hemisphere dopaminergic activation system for the implementation of predetermined motor programs.

Cortical Regions Associated with Perceiving, Naming, and Knowing about Colors

Results indicate that retrieving previously acquired information about an object's typical color does not require reactivation of brain regions that subserve color perception.

Color blindness, perceptual interference, and hypnosis.

The hypnosis group differed significantly from the theoretical distribution, while the pretend group did not differ significantly fromTheoretical distribution of correct responses expected of truly color-blind subjects.

The functional anatomy of imagining and perceiving colour

The findings reconcile neurological case studies suggesting a double dissociation between deficits in colour imagery and perception and point to anterior fusiform, parahippocampal gyri and hippocampus as the location for stored representations of coloured objects.

Where the imaginal appears real: a positron emission tomography study of auditory hallucinations.

Inappropriate activation of the right anterior cingulate may lead self-generated thoughts to be experienced as external, producing spontaneous auditory hallucinations.

Abstract This paper examines research on three hypnotic phenomena: suggested amnesia, suggested analgesia, and “trance logic.” For each case a social-psychological interpretation of hypnotic behavior
