Two-tone rate suppression in auditory-nerve fibers: dependence on suppressor frequency and level.
The growth of two-tone rate suppression with suppressor level was studied for auditory-nerve fibers in anesthetized cats. The level of a tone at the characteristic frequency (CF) was adjusted by an adaptive procedure (PEST) so that, when presented with a suppressor tone, the CF tone would produce a criterion discharge rate. Suppression (in dB) was defined as the CF-tone level that met criterion...
متن کاملFrequency discrimination in forward and backward masking.
Frequency difference limens for pure tones preceded by a forward masker or followed by a backward masker were obtained across a wide range of signal levels. Relkin and Doucet [Hear. Res. 55, 215-222 (1991)] have shown that at a masker-signal delay of 100 ms, the thresholds of high-SR (spontaneous rate) auditory-nerve fibers are recovered, while the low-SR fiber thresholds are not. Therefore, fo...

15 صفحه اول: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولSpatial frequency effects in masking by light.
Observers detected briefly pulsed sine-wave gratings presented with various asynchronies before, during or after a 700 msec conditioning flash. Although the conditioning flash raised increment thresholds for detection of both low and high spatial frequency gratings, shapes of the masking curves differed. Curves for low spatial frequency gratings exhibited peaks at the conditioning field on and ...
