A comprehensive survey of the research evidence for our capacity to generate images, and the processes involved, by a premier researcher of daydreaming and imagination for more than 50 years. Drawing on a lifetime of experience both practicing psychotherapy and training clinicians, Singer argues forcefully that using imagery in psychotherapy is easily integrated into a variety of therapeutic approaches. Clinicians are shown how to make use of their patients' as well as their own ability to generate images and that these techniques can be used regardless of the clinician's theoretical orientation. Includes case examples and autobiographical material.
