Forty stutterers and 40 nonstutterers were tested for susceptibility to delayed auditory feedback (DAF) while reading passages under amplified delay conditions. Susceptibility to DAF of stutterers was significantly higher than that of nonstutterers. In the nonstuttering group, men were more susceptible to DAF than women, but in the stuttering group, there(More)
The feature size of LSI is getting smaller year by year, increasing random variability between the elements. These days, the problem of the variability imposes too severe timing constrains to design circuit with enough timing margin. This paper estimates the worst delay more realistically by statically evaluating delay variation caused by various input data(More)
A model of consisting of excitatory and inhibitory processes was proposed for visual evoked potentials (VEPs) from the midline occiput (Oz). On and off stimulation of circular lights subtending 2 degrees and 5 degrees in visual angle were presented with luminance contrast of 1.0, 2.2, and 3.4. The typical triphasic data from a well trained male subject were(More)
Sex difference in susceptibility to DAF (delayed auditory feedback) in oral reading of texts was investigated. Forty adults, 20 males and 20 females with normal speech and hearing abilities, read aloud two kinds of texts, one easy to read and the other difficult, under two conditions, NAF (normal auditory feedback) and DAF. Delays were 150, 200, 300, 400(More)
The effect of delayed auditory feedback (DAF) was investigated by reciting melodies of three levels of complexity (simple, medium and complex), consisting of five tones and five beats per second. Four normal adult subjects recited these melodies with/pa/under 10 conditions of 0 to 900 ms delay (100 ms step). DAF effect was measured by DAF index(More)
