The practitioner or teacher may facilitate this process in person to an individual or a group or you may do it with a virtual group. Alternatively, the participant or patient may follow guidance provided by a sound recording, video, or audiovisual media comprising spoken instruction that may be accompanied by music or sound.Sources: Morris, C., The use of self-service technologies in stress management: A pilot project.

Mental imagery in everyday life

There are two fundamental ways by which mental imagery is generated: voluntary and involuntary.

The involuntary and spontaneous generation of mental images is integral to ordinary sensory perception, and cognition, and occurs without volitional intent. Meanwhile, many different aspects of everyday problem solving, scientific reasoning, and creative activity involve the volitional and deliberate generation of mental images.Sources: Gardner, M., Creating minds. New York: Basic Books, 1953. Antonietti, A., and Baldo, S., Undergraduates conceptions of cognitive functions of mental imagery. Perceptual and Motor Skills, Vol. 78, No. 1, 1994, pp. 160–162.

G., De Beni, R., and Cornoldi, C., The generation and transformation of visuo-spatial mental images. In M. Denis, R. H. Logie, C. Cornoldi, M. de Vega, and J.

Science, Vol. 171 No. 3972, 1971, pp. 701–703.

Involuntary

The generation of involuntary mental imagery is created directly from present sensory stimulation and perceptual information, such as when someone sees an object, creates mental images of it, and maintains this imagery as they look away or close their eyes; or when someone hears a noise and maintains an auditory image of it, after the sound ceases or is no longer perceptible.

Voluntary

Voluntary mental imagery may resemble previous sensory perception and experience, recalled from memory; or the images may be entirely novel and the product of fantasy.Hitch, G. J., Brandimonte, M. A., and Walker, P., Two types of representation in visual memory—Evidence from the effects of stimulus contrast on image combination. Memory and Cognition, Vol. 23, No. 2, 1995, pp. 147–154.Pearson, D. G., and Logie, R. H., Effects of stimulus modality and working memory load on mental synthesis performance. Imagination, Cognition, and Personality, Vol. 23, Nos. 2-3, 2004, pp. 183–192.

Technique

The term guided imagery denotes the technique used in the second (voluntary) instance, by which images are recalled from long-term or short-term memory, or created from fantasy, or a combination of both, in response to guidance, instruction, or supervision. Guided imagery is, therefore, the assisted simulation or re-creation of perceptual experience across sensory modalities.Kosslyn S.M., Ganis G., Thompson W.L. Neural foundations of imagery. Nature Reviews Neuroscience. Vol. 2, No. 9, 2001, pp. 635–642.Pearson D.G. Mental imagery and creative thought. Proceedings of the British Academy. Vol. 147, 2007; pp. 187–212.

Clinical investigation and scientific research

Mental imagery can result from both voluntary and involuntary processes, and it comprises simulation or recreation of perceptual experience across all sensory modalities,Sources: Kosslyn, S.

In experimental and cognitive psychology, researchers have concentrated primarily on voluntary and deliberately generated imagery, which the participant or patient creates, inspects, and transforms, such as by evoking imagery of an intimidating social event, and transforming the images into those indicative of a pleasant and self-affirming experience.

In psychopathology, clinicians have typically focused on involuntary imagery which "comes to mind" unbidden, such as in a depressed person's experience of intrusive unwelcome negative images indicative of sadness, hopelessness, and morbidity;Sources: Kosslyn, S.
