PSYB65H3 Chapter Notes - Chapter 10 : Absolute Pitch, Carl Wernicke, Frontal Lobe
Document Summary
Aphasia: inability to speak or comprehend language despite the presence of normal comprehension and intact vocal mechanisms. Broca aphasia is the inability to speak fluently despite the presence of normal comprehension and intact vocal mechanisms. Wernicke aphasia is the inability to understand or to produce meaningful language even though word production remains intact. Amplitude: stimulus intensity; in audition, roughly equivalent to loudness, graphed by the increasing height of a sound wave. Amusia: tone deafness inability to distinguish between musical tone. Basilar membrane: receptor surface in the cochlea that transduces sound waves into neural activity. Broca"s area: anterior left hemisphere speech area that functions with the motor cortex to produce movements needed for speaking. Cochlea: inner ear structure containing the auditory receptor cells. Cochlear implant: electronic device implanted surgically into the inner ear to transduce sound waves to neural activity and allow a deaf person to hear. Decibel (db): measure of a relative physical intensity of sound.
