In P. M. A. Rabbitt & S. Dornic (Eds. Selective Attention: Definition, Types, and Examples (PDF) Selective Attention - ResearchGate Whilst there is little doubt that feature integration theory (Treisman & Gelade, 1980) was Anne Treisman's single most influential contribution to psychological science, an earlier contribution that should not be overlooked is her attenuation theory of selective attention (Treisman, 1964a, 1964b, 1964c, 1964d; Treisman & Riley, 1969).This theory derived from the study of auditory attention . For this reason, and as illustrated by the examples below, Treisman proposed attenuation theory as a means to explain how unattended stimuli sometimes came to be processed in a more rigorous manner than what Broadbent's filter model could account for. If demands are high, attenuation becomes more aggressive, and only allows important or relevant information from the unattended message to be processed. Other researchers have obtained similar results with messages including lists of words and musical melodies. Participants with training or practice can more effectively perceive content from the unattended channel while attending to another. Why embracing pain, discomfort, or suffering, is a need for happiness? This model states that selective attention temporarily reduces the strength or effectiveness of distracting stimuli instead of blocking them completely. This implies some analysis of the meaning of stimuli must have occurred prior to the selection of channels. 3 . An example of this can be seen in the statement the recess bell rang, where the word rang and its synonyms would experience a lowered threshold due to the priming facilitated by the words that precede it. The dichotic listening tasks involves simultaneously sending one message (a 3-digit number) to a persons right ear and a different message (a different 3-digit number) to their left ear. Attenuated information passes through all the analyzers only if the threshold has been lowered in their favor, if not, information only passes insofar as its threshold allows. This is an important process as there is a limit to how much information can be processed at a given time, and selective attention allows us to tune out insignificant details and focus on what is important. The hierarchical process also serves an essential purpose if inputs are identical in terms of voice, amplitude, and spatial cues.

This model is consistent with ideas of subliminal perception; in other words, that you dont have to be aware of or attending a message for it to be fully processed for meaning. His theory is based on the earlier model by Broadbent. In varying degrees of efficiency, we have developed the ability to focus on what is important while blocking out the rest. ), Attention and performance (Vol. Verywell Mind's content is for informational and educational purposes only.
