Division of Attention Relative to Response Between Attended and Unattended Stimuli.
Kantowitz, Barry H.
Research was conducted to investigate two general classes of human attention models, early-selection models which claim that attentional selecting precedes memory and meaning extraction mechanisms, and late-selection models which posit the reverse. This research involved two components: (1) the development of simple, efficient, computer-oriented methods for generating rigorously precise stimulus material (these required human attention experiments); and (2) the execution of two experiments which employed computer-generated stimuli. The first experiment examined the filtering characteristics of attention mechamisms when subjects were required to select from either acoustically or semantically similar competing messages. Results show that semantic similarity is disruptive only at a slow presentation rate, while the effects of acoustic similarity do not depend on presentation rate. In the second experiment, subjects performed a tone detection task in one ear, while simultaneously monitoring a digit sequence presented in the opposite ear. Digits were recalled following presentation. Tone detection performance decreased as the number of digits to be recalled increased. Both findings are interpreted as supporting early-selection attention models. (Author)
