Sine-Wave Response of the Visual System I The Mach Phenomenon*

Model of visual adaptation and contrast detection

“…For example, the lateral interaction in the eye of Limulus has been characterized as feedback and subtractive (Hartline & Ratliff, 1958). 3 Various subtractive models of lateral interaction have been proposed for vision (e.g., Schade, 1956;von Bekesy, 1960;Lowry & DePalma, 1961;Rodieck, 1965;Nachmias, 1968). A desirable feature of these models is that, because they are linear, the full power of linear analysis applies.…”

Effect of ramp-like contours upon perceived size and detection threshold

“…Although spatial interactions are not linear in all respects, the requirements of the present situation are probably met (Thomas, 1968a). One shortcoming of this treatment is that both theoretical curves (von Bekesy, 1960) and empirical measurements (Lowry & De Palma, 1961) suggest that the perceived width should be closer to W 2 than was found in this study. In this respect, the data of Charman (1963) provide better support for the analysis.…”

Apparent image rotation in stereoscopic vision: The unbalance of the pupils

“…The question of how much this lateral spread is modified by the lateral inhibition has also been discussed recently (Bliss & Macurdy, 1961;Lowry & DePalma, 1961;Bryngdahl, 1964;Menzel, 1965;Ratcliff, 1965;Campbell, 1968). Lateral inhibition in the retina and the higher level of the nervous system does seem to reduce the effectiveness of the wide spread of the irradiation, especially for the lower levels of the luminance.…”
