What is filter attenuation theory in psychology?

Filter-attenuation theory Filter- attenuation theory was developed by Triesman by modifying Broadbent’s theory. This theory proposes that the stimuli not getting access to the selective filter at a given moment of time are not completely blocked. The filter only attenuates (weakens) their strength.

What did Donald Broadbent propose?

Broadbent Filter Model In 1958, Donald Broadbent proposed the Filter Model of Attention which states that there is a sensory buffer where all sensory stimuli enter at any given time.
