Psychoacoustics. Psychoacoustics is the branch of psychophysics involving the scientific study of sound perception and audiology —how the human auditory system perceives various sounds. More specifically, it is the branch of science studying the psychological responses associated with sound (including noise, speech, and music ).
Schematic diagram of the human ear. Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. [1] The academic field concerned with hearing is auditory science . Sound may be heard through solid, liquid, or gaseous ...
Ames room. Photograph of two adults standing in an Ames room, apparently with a significant difference in size. An Ames room is a distorted room that creates an optical illusion. Likely influenced by the writings of Hermann Helmholtz, [1] it was invented by American scientist Adelbert Ames Jr. in 1946, [2] and constructed in the following year.
Early selection models of attention [ edit] The early selection model of attention, proposed by Broadbent, [1] posits that stimuli are filtered, or selected to be attended to, at an early stage during processing. A filter can be regarded as the selector of relevant information based on basic features, such as color, pitch, or direction of stimuli.
61734. Anatomical terminology. [ edit on Wikidata] The ear canal ( external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear. The adult human ear canal extends from the auricle to the eardrum and is about 2.5 centimetres (1 in) in length and 0.7 centimetres (0.3 in) in diameter.
Visual lateral inhibition is the process in which photoreceptor cells aid the brain in perceiving contrast within an image. Electromagnetic light enters the eye by passing through the cornea, pupil, and the lens (optics). [15] It then bypasses the ganglion cells, amacrine cells, bipolar cells, and horizontal cells in order to reach the ...
Auditory imagery is a form of mental imagery that is used to organize and analyze sounds when there is no external auditory stimulus present. This form of imagery is broken up into a couple of auditory modalities such as verbal imagery or musical imagery. This modality of mental imagery differs from other sensory images such as motor imagery or ...
In perceptual psychology, a stimulus is an energy change (e.g., light or sound) which is registered by the senses (e.g., vision, hearing, taste, etc.) and constitutes the basis for perception. [2] In behavioral psychology (i.e., classical and operant conditioning), a stimulus constitutes the basis for behavior. [2]
