e selective filter was reset to a different channel. However, since subjects did hear words without knowing; it, it might be assumed that subjects registered the words due to some characteristic (contradiction of transition probabilities on the attended channel), perhaps before the selective filter could' identify them.
Others have concluded that there is a single channel system for analyzing meaning and matching signals, with a kind of dictionary and store of probabilities learned with language use, which analyzes prior to the filter. Some words have lower thresholds for activation (important words). Another view states that rejected messages are occasionally sampled or monitored. These possibilities are stated as more economical than a reduplication of analysis before or after the selective filter. Explanations are needed to show why a few important works and words made contextually highly probable, are sometimes beard from the rejected ear. Triesman offers limited information without significantly substantiated explanations.
Information processing is part of the human cognitive processing system. Theories of attention attempt to explain this system. Some state that the human processing system is multi-channel at early stages and single-channel after that. In this case the system has a bottleneck which results in some information receiving complete processing. For Triesman's attenuation theory (a bottleneck theory of attention), the bottleneck comes after the registering of simple physical characteristic and before identification. For others the bottleneck is found after identification and before preparation of a response.
Triesman's theory alone offers limited information to assist with the understanding of cognitive processes, however it's focus on attenuation presents one aspect of attention which helped lead to the further investigation of selection. For example, studies show that early selection occurs in som...
