Nonverbal Auditory Perception Test
Definition
The Nonverbal Auditory Perception Test (NAPT) is an assessment used to measure a person’s ability to recognize and discriminate environmental sounds, such as speech, music, and other noises. This test has been used in a variety of contexts, including educational, clinical, and research settings. It is designed to assess a person’s ability to interpret auditory information without relying on verbal or written cues.
History
The Nonverbal Auditory Perception Test (NAPT) was developed in the late 1970s by Dr. Robert F. Portman, a professor of psychology at the University of Oregon. The NAPT was originally designed to be used as an assessment tool for individuals with language and developmental delays. Since then, it has been used in various contexts, including clinical, educational, and research settings.
Characteristics
The NAPT is composed of a series of auditory stimuli that are presented one at a time. These stimuli range from simple environmental sounds (e.g., birds chirping) to more complex sounds (e.g., speech or music). The test is typically administered in a one-on-one setting, in which the examiner presents the stimuli and records the responses. The responses are typically recorded on an answer sheet and scored according to a predetermined criteria.
The NAPT can be used to assess a variety of auditory processing abilities, including sound discrimination, sound recognition, and sound sequencing. It is also used to evaluate a person’s ability to integrate auditory information with other sensory modalities, such as vision and touch.
