GSR latency, mean amplitude, and quiescent or post reading time of seven male college students during and after reading paragraphs of 20/50 acuity level or 1.5 mm letters at five levels of accommodative stimulation, −2.00 D to +2.00 D, were recorded by the Beckman Dynograph with miniature skin electrodes. Results showed that this range of stimulation has no effect on latency or post reading response time, but that the curve of amplitude vs. accommodative stimulation has three segments, a plateau in the middle separating two positively linear curves. A separation of at least 2.00 D of accommodative stimulation is required for a difference in mean amplitude to appear.
