“…A growing body of literature suggests that the central retinal regions are concerned primarily with form perception and object recognition, while the periphery is specialized for visual localization of objects and orientation in space (Held, 1968(Held, , 1970(Held, , 1971Ingle, 1967Ingle, , 1973Schneider, 1967Schneider, , 1969Trevarthen, 1968). Recent research on the visual mediation of the sensation of ego-motion or vection' and stabilization of posture supports this differentiation between central and peripheral vision (Brandt, Dichgans, & Koenig, 1973;Dichgans & Brandt, 1974;Held, Dichgans, & Bauer, 1975;Lestienne, Soechting, & Berthoz, 1977).…”

The effect of refractive error and luminance on circularvection, the illusory sensation of self-motion resulting from rotation of the visual field, was determined. Neither reduction of luminance to levels near absolute scotopic threshold nor induced refractive errors of more than 16 diopters abolished circularvection or influenced any of its latency measures. The results are discussed in terms of the role of the peripheral visual field and the nature of the visual stimulus in ego orientation.A growing body of literature suggests that the central retinal regions are concerned primarily with form perception and object recognition, while the periphery is specialized for visual localization of objects and orientation in space (

“…Colliculectomized subjects in a discrimination task could discriminate simple patterns, but could not orient or locomote directly to the correct pattern. Conversely, animals with ablations of the visual cortex displayed an impaired ability to discriminate patterns, but no loss of ability to orient and localize.These results, in addition to those of Held (1968), Ingle (1967), and Trevarthen (1968, have led these authors to postulate two different modes of visionthe first concerned with "location" and the second with "identification." The term "location," however, refers to a wide range of behaviors which require the pickup of different types of stimulus information, and which demand varying degrees of visuomotor integrative ability in order to be performed.…”

Held and Schneider and others have postulated two, functionally separate, modes of vision-one concerned with localization, the second with identification-and have suggested that the superior colliculus is crucial for the perception of location. Colliculectomized hamsters were tested on two localization tasks. No deficit in depth perception was observed. Perceptual-motor integration necessary to perform a search task was severely disrupted, however. These results suggest that the superior colliculus functions in the control of fine visual-motor coordination.Research by Schneider (1969) has specified anatomical loci for two functional mechanisms of vision in golden hamsters. Colliculectomized subjects in a discrimination task could discriminate simple patterns, but could not orient or locomote directly to the correct pattern. Conversely, animals with ablations of the visual cortex displayed an impaired ability to discriminate patterns, but no loss of ability to orient and localize.These results, in addition to those of Held (1968), Ingle (1967), and Trevarthen (1968, have led these authors to postulate two different modes of visionthe first concerned with "location" and the second with "identification." The term "location," however, refers to a wide range of behaviors which require the pickup of different types of stimulus information, and which demand varying degrees of visuomotor integrative ability in order to be performed. The question arises that perhaps a lesion in a specific area of the brain could interfere with an animal's performance on one task involving "location" while another behavior that can be categorized under the same heading remains intact. That this may be the case is suggested by previous studies involving ablations of the superior colliculus. For example, Lashley (1937) demonstrated that rats with lesions in the superior colliculus could negotiate jumps of between 20 and 40 cm to a platform without any difficulty, and found that the The authors wish to thank Gerald Schneider for his advice on the surgical procedures used in these experiments, P. A. Cabe for his suggestions concerning the open-field test, and E. J. Gibson for her advice and encouragement. Requests for reprints should be sent to Richard R. Rosinski,

“…W e offer no direct tests about any underlying neural substrate. Rather it is our reading of history that although there has long been evidence for an object and a spatial com ponent to the visual system of some animals (Held, 1968;Ingle 1967;Schneider 1967 ;Trevarthen 1968), until cognitive psychologists began considering the neural substrate of imagery, visual imagery rem ained a unitary concept. W e therefore base our object versus spatial division on neuropsychological data.…”
