Thanks for checking out my. Light, in the form of electromagnetic energy, is the stimulus for vision. The basic type of auditory stimulus in Presentation is the sound stimulus. Presentation is capable of simultaneously playing multiple sound stimuli, even during the simultaneous presentation of other stimuli. Auditory stimuli are created by objects (e.g., a human speaking, someone playing a musica
l instrument, a tree falling in the forest) that produce changes in pressure in some elastic medium (typically air, though other elastic media work as well), ultimately transduced by hair cells in the inner ear. Sound stimuli were noise signals successively applied to loudspeakers placed along an arc, simulating movement of a sound source. A subject stood on a platform centered relative to the arc so that the sagittal plane of the subject coincided with the plane of the arc.
