Final answer:
Psychogenic Voice Therapy is based on the psychological assumption influenced by Freud's psychoanalysis, proposing that voice disorders can stem from emotional causes. The therapy focuses on uncovering and addressing suppressed psychological issues to improve voice function. It demonstrates an interdisciplinary approach between psychology and speech therapy.
Step-by-step explanation:
The assumption that Psychogenic Voice Therapy is based on is closely related to Sigmund Freud's work on psychoanalysis, which uses the "talking cure" to treat patients. Psychogenic Voice Therapy assumes that certain voice disorders are the result of emotional or psychological factors rather than physical causes.
This form of therapy is based on the notion that by addressing underlying psychological issues through a therapeutic conversation between the therapist and the patient, it's possible to alleviate the voice problems.
Freud believed that the human mind could be impeded in its progression toward mental health by unresolved issues from childhood. During therapy sessions, experiences like dreams and memories are explored to uncover any suppressed ideas that may be causing physical symptoms, including voice disorders.
These ideas are commonly rooted in developmental stages and traumas linked to sexual identity as posited in Freud's theories.
Moreover, another perspective comes from Elizabeth Loftus, who challenges the idea of repressed memories that can be recovered.
Critical of methods such as hypnosis and guided visualization, which are sometimes employed in psychogenic therapies, her work suggests a need for caution in distinguishing between authentic memories and those that may be suggested or implanted during therapy.
