Normal subjects had to name German compound nouns which were presented tachistoscopically. The compound nouns were displayed either unilaterally to the left or right visual field, or bilaterally with one element to the left and one to the right visual field. A distinction was made between the bilateral conditions as to whether the representation of the… (More)
Normal subjects were asked to estimate the total surface of two black spots presented tachistoscopically, either both to the right or both to the left visual field, or bilaterally to either visual field. Performance was highest with unilateral left visual field presentation and lowest with bilateral presentation of the spots. Interhemispheric integration… (More)
Man's spatial perception was investigated on the basis of acoustic input in the extrapersonal frame of reference. Sounds from a two-dimensional loudspeaker array outlined sequentially the contours of various digits. The underlying mechanisms involved in this auditory-spatial task were analyzed according to alterations in the vertical and horizontal spread… (More)
An X-ray reflectivity theory on the determination of the density profile of a molecular liquid under nanometre confinement is presented. The confinement geometry acts like an X-ray interferometer, which consists of two opposing atomically flat single-crystal mica membranes with an intervening thin liquid film of variable thickness. The X-rays reflected from… (More)
Fixation accuracy was related to perception of laterally presented consonants. Small left-eye fixation inaccuracy influenced perceptual performance of 8 men and 8 women.
Normal subjects had to name German compound nouns which were presented tachistoscopically. The compound nouns were displayed either unilaterally to the left or right visual field or bilaterally with one element to each visual field. In the bilateral condition a distinction was made as to whether familiar or unfamiliar arrangement of the elements was used.… (More)
Under conditions of tachistoscopic stimulation normal subjects were presented visuospatial stimulus pairs which had to be integrated interhemispherically. The presence of a pronounced cognitive style improves the interhemispheric integration of this type of information. Two interpretations are discussed. The first explains the observed improvement with a… (More)
Groups of patients with cortical lesions were subjected to a uniquely developed procedure to test auditory-spatial perception. The stimuli were comprised of a sound source, which sequentially outlined a pattern within a 10 X 10 matrix of loudspeakers. Simple sound patterns, which "moved" across the loudspeaker array only once or twice, were equally well… (More)
