Attentional Processes In Auditory Discriminations, William A. Ahroon
Attentional Processes In Auditory Discriminations, William A. Ahroon
Graduate Dissertations and Theses
A set of experiments is described which assessed the ability of human observers to monitor two earphone channels in order to perform one or two independent frequency discriminations. Performance (d′) was significantly poorer with dichotic stimulus presentation than in monaural control conditions. A detailed analysis of the data suggested that two factors were involved in the dichotic performance deficits. The first factor was a limited ability of the observers to perceptually separate the different stimuli presented to the two earphone channels. Under certain stimulus conditions, the channel-separation factor was significant enough to produce a low performance ceiling which overshadowed additional …

Verbal Short-Term Storage And Analysis-By-Synthesis Of Speech : Evidence For Common Mechanisms, James W. Aldridge
Graduate Dissertations and Theses
Since the late 1950s a great deal of research has been directed toward elucidating the process(es) by which humans retain verbal material for short intervals of time. The purpose of the present paper will be to explore the extent to which such memorial processes can be identified with processes which may be employed in information processing tasks in general, and speech perception and/or production in particular.
