| the flicker response contour for the crayfish. i. | the f - log i curve for threshold response to visual flicker has been determined for the crayfish cambarus bartoni. as predicted on the basis of the higher curvature of the optic surface, the flicker response contour is more asymmetrical than for bee and dragonfly nymph under comparable conditions of temperature and light time fraction of flash cycle. the mechanical origin of this asymmetry is thus confirmed, and is further supported by the similar forms of the f - log i curves in bee, dragonfly ... | 1939 | 19873135 |
| the flicker response contour for the isopod asellus. | the flicker response contour for the isopod asellus is a simple probability integral (f - log i) over the whole determinable range (f = 1 to 51). this contrasts with the "distorted" asymmetrical curves obtained with apis, anax, and other arthropods with large convex eyes. the explanation of the distortion as due to mechanical conditions affecting photoreception is therefore confirmed, as the structure of the asellus eye does not make such a factor likely to be expected for this case. the asellus ... | 1939 | 19873114 |
| on the variability of critical illumination for flicker fusion and intensity discrimination. | from the data of experiments with bees in which threshold response is employed as a means of recognizing visual discrimination between stripes of equal width alternately illuminated by intensities i(1) and i(2), it is shown that the detectable increment of intensity deltai, where deltai = i(2) - i(1), is directly proportional to sigma(i2) (i(1) being fixed). from tests of visual acuity, where i(1) = 0 and the width of the stripes is varied, sigma(i2) = ki(2) + const.; here i(2) = deltai, and del ... | 1936 | 19872945 |
| the validity of talbot's law for the eye of the honey bee. | by presenting to bees two illuminated fields, equal in brightness, of which one is flickering and the other stationary we find that on account of the bee's positive phototropic response equal numbers of bees travel to both fields. we thus can assume that talbot's law is valid for the eye of the bee. | 1935 | 19872895 |
| the effect of light intensity, area, and flicker frequency on the visual reactions of the honey bee. | 1. for the phototropic reaction of bees, the stimulating effects of two illuminated fields differing in intensity and area become equal when the product of area and intensity is the same for both fields. 2. the effect of two areas differing in size and flicker frequency is the same for the bee, when the product of area and flicker frequency is equal for both fields. 3. if two patterns of the same character but varying in size and coarseness are presented to bees for free choice, a 1:1 ratio of c ... | 1935 | 19872894 |
| critical frequency of flicker as a function of intensity of illumination for the eye of the bee. | the bee's characteristic response to a movement of its visual field is used for the study of the relation between critical frequency of flicker and illumination. the critical flicker frequency varies with illumination in such a way that with increasing flicker frequency the intensity of illumination must be increased to produce a threshold response in the bee. the illuminations required to give a response in a bee at different flicker frequencies closely correspond to the intensities for thresho ... | 1933 | 19872764 |
| the variability of intensity discrimination by the honey bee in relation to visual acuity. | variation in the determined magnitudes of the difference in brightness between alternating members of a system of stripes requisite for the elicitation of a threshold response in bees shows that the intensity of excitation, as a function of width of stripe and of intensity of illumination, is determined by the intensity of illumination and by the frequency of occurrence of divisions between bright and less bright bars. the variation of deltai is limited by the intensity of excitation, so that th ... | 1933 | 19872739 |
| on the relation between measurements of intensity discrimination and of visual acuity in the honey bee. | 1. bees respond by a characteristic reflex to a movement of their visual field. by confining the field to a series of parallel stripes of two alternating different brightnesses it is possible to determine for any width of stripe, at any brightness of one of the two sets of stripes, the brightness of the second at which the bee will first respond to a displacement of the field. thus the relations between visual acuity and intensity discrimination can be studied. 2. for each width of stripe and vi ... | 1933 | 19872738 |
