Kendra Cherry, MS,is the author of the "Everything Psychology Book (2nd Edition)"and has written thousands of articles on diverse psychology topics. Attenuation theory is a model of selective attention proposed by Anne Treisman, and can be seen as a revision of Donald Broadbent's filter model. This means people can still process the meaning of the attended message(s). Vis cogn. Sometime during shadowing, the stimuli would then swap over to the opposite side so that the formerly shadowed message was now presented to the unattended ear. Naive subjects could only detect 8% of digits appearing in either the shadowed or non-shadowed message; Moray (an experienced shadower) detected 67%. She theorized that instead of "bottlenecking" what information passed to our attention, we just "attenuated" it. How the deployment of visual attention modulates auditory distraction Verywell Mind articles are reviewed by board-certified physicians and mental healthcare professionals. The type of information that lower thresholds according to Treisman's attenuation theory words that have subjective importance and words that signal danger can still be recognized even at low volumes. For two messages identical in content, it has been shown that by varying the time interval between the onset of the irrelevant message in relation to the attended message, participants may notice the message duplicity. Interestingly, if the speaker of the unattended message switched from male to female (or vice versa) or if the message was swapped with a 400-Hz tone, the participants always noticed the change. The early studies all used people who were unfamiliar with shadowing and so found it very difficult and demanding. Other researchers have obtained similar results with messages including lists of words and musical melodies. [1] The level of attenuation can have a profound impact on whether an input will be perceived or not, and can dynamically vary depending upon attentional demands. Voltage modulations were observed after 100ms of stimuli onset, consistent with what would be predicted by attenuation of irrelevant inputs. [9] Context acts by a mechanism of priming, wherein related information becomes momentarily more pertinent and accessible lowering the threshold for recognition in the process. Context acts by a mechanism of priming, wherein related information becomes momentarily more pertinent and accessible lowering the threshold for recognition in the process. As mentioned previously, changes in pitch can also play a role in selectivity.. Anne Treisman, in 1964, proposed an attenuation theory of attention in which the processing of unattended information is attenuated. [9] The Deutsch & Deutsch model was later revised by Norman in 1968, who added that the strength of an input was also an important factor for its selection.

However, she argued that the unattended sensory inputs (the ones that were not chosen . Verywell Mind's content is for informational and educational purposes only. Therefore, the filter theory cant be right to suggest that unattended information is completely blocked at the sensory analysis level. [1], Variations upon this method involved using identical messages spoken in different voices (e.g., gender), or manipulating whether the message was composed of non-words to examine the effect of not being able to extract meaning.
