As the resulting image becomes increasingly larger on the perceiver's retina, i.e., when an object looms, there is an automatic physiological response to perceive the object as an approaching object or surface, instead of one that is stationary or receding. Evidence indicates that looming perception is not limited to the visual modality, but can occur due to auditory or even tactile stimuli.
When a perceived image grows larger on the retina, i.e., when an object draws near, there is an automatic physiological response that causes the perceiver to view the object as approaching rather than stationary. Research suggests that this phenomenon extends beyond visual perception and can also be triggered by auditory or tactile inputs.
