WebEarly 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.
