Purpose: Disorders of motivation substantially impair an individual’s ability to communicate with their families, therapists, and doctors. One method of overcoming initiation deficits is by utilizing the telephone effect, which is the ability for individuals with severe motivation deficits to communicate more readily when speaking on a telephone. However, little is available in the extant literature on how this effect works or how best to integrate this into patient care. This article aims to provide the first report of a proposed mechanism underlying the telephone effect and the first published procedures for eliciting this effect. Design: This is largely a review article that also contains descriptions of clinical procedures for eliciting the telephone effect with 2 patient populations: acute inpatients following brain injury and dementia residents. A case vignette is also provided. Results: We propose that the telephone effect is the result of an interaction between the patient and environment, and occurs because of Gibson’s (1979) law of affordances. The use of this theory provides an explanation of the behaviors often observed when attempting to elicit this effect (i.e., disruption of the effect when using a cellular phone). Moreover, we argue that this can, and does, apply to social interactions as well. Conclusions/Implications: The telephone effect is an understudied phenomenon that provides a means of improving care for individuals with disorders of motivation. Future directions include systematic research into the telephone effect and further investigation of the mechanism underlying this effect.
