[3] However, attended and unattended information pass through the filter, to a second stage of selection on the basis of semantic characteristics or message content. Therefore, based on physical characteristics, the selective filter allows for certain stimuli to pass through the filter for further processing, while unattended stimuli will be filtered out and lost. drawback: you waste too much of your body resources processing things you may not need.

These processes assign to the perceptual processes. Conditioned participants to associate electric shock with names of US cities. [1] Broadbent was the first to describe the human attentional processing system using an information processing metaphor. all stimuli are processed (attended and unattended) before selection. Accuracy of their answers dropped significantly, which again supports Broadbent's filter theory and an early selection model because switching from ear to ear is difficult and goes against the filter. The nature of the attenuation process has never been precisely specified. The results of neurophysiology experiments on selective attention are compatible with this supposition. [15] Treisman stated that instead of a filter, people have an attenuator and it identifies messages based on its physical properties or by higher level characteristics, such as meaning. This supports Broadbent's filter theory and an early selection model because participants filtered the information based on ear. Other researchers have demonstrated the 'cocktail party effect' (Cherry, 1953) under experimental conditions and have discovered occasions when information heard in the unattended ear 'broke through' to interfere with information participants are paying attention to in the other ear. Participants first reported the information from one ear and then switched filters in order to report the digits presented to the second ear.

The dichotic listening tasks involves simultaneously sending one message (a 3-digit number) to a person's right ear and a different message (a different 3-digit number) to their left ear. Clearly, then, the unattended message was being processed for meaning and Broadbent's Filter Model, where the filter extracted on the basis of physical characteristics only, could not explain these findings. The evidence suggests that Broadbent's Filter Model is not adequate, it does not allow for meaning being taken into account. This time, participants heard a mixture of numbers and words presented to each ear, such as, "Dear 7 Jane" in the left ear and, "9 Aunt 6" in the right ear and were asked to report back what they heard.
