Compare and contrast Broadbent's filter theory with Treisman's modified filter theory. Which theory best accounts for the ways in which people select what they attend to from the massive amount of information entering the sensory registers?

1. Compare and contrast Broadbent's filter theory with Treisman's modified filter theory. Which theory best accounts for the ways in which people select what they attend to from the massive amount of information entering the sensory registers?

Both Broad Broadbent's filter theory and Treisman's modified filter theory are theories of focused auditory attention.

However, Broadbent's filter theory was the first detailed theory of focused auditory attention. The key assumptions Broadbent (1958) made are as follows:

1. Two stimuli presented at the same time gain access simultaneously to the sensory buffer.
2. One of the stimuli then passes through a filter?selected on the basis of its physical characteristics.
3. The filter prevents overloading of the mechanism past the filter (STM), which thoroughly processes the input but which only has a limited capacity. (http://www.psypress.com/pip/resources/slp/topic.asp?chapter=ch06&topic=ch06-sc-01).
4. Broadbent also assumed that there was no processing of the meaning of the unattended message, but von Wright et al. (1975; see PIP p.195) found that meaning can be processed without awareness. By pairing electric shocks with words later presented in the unattended message, they showed that Broadbent was wrong to assume that the meaning of the unattended message receives no processing (Lachman, Lachman, & Butterfield, n.d). ...

Solution Summary

This solution compares Broadbent's Filter Theory with Treisman's Modified Filter Theory, and explains which theory best accounts for the ways in which people select what they attend to from the massive amount of information entering the sensory registers.
