Abstract
The flicker response contour (critical flash-intensity as a function of flash-frequency) was detd. at several temps. for the turtle Pseudemys scripta. As with other animals, the curve is moved to a lower level on the intensity scale by an elevation of temp., without change of the maximum flash-frequency and without change of shape. The curve is accurately described (F[long dash]log I) as a probability integral. Of the 3 parameters of this function only the abscissa of the inflection point is a function of temp. The reciprocal of the critical intensity at any level of F obeys the Arrhenius equation (12[degree][long dash]36[degree]), with a critical temp. at 30[degree]; below 30[degree][mu] = 27,000 cal.; above 30[degree], 12,000 cal.This publication has 7 references indexed in Scilit:
