What reading level is The After Image Threshold book?
To quickly assess the difficulty of the text, read a short excerpt:
The results oi 1900 experiments on 3 observers showed that the accuracy of discrimination for areas was, on the average, about \ greater for 200 g. Than for 800 g. \ By placing thin circular cards upoi^ the hand and apply- ing pressure upon these, we studied the effect of variations in the area on the so-called tactile threshold. The areas were approximately i mm. , 10 mm. And 90 mm. The aver- ages of the corresponding threshold values, based upon 60 experiments, were for F. , . 2 g. , . 9 g. A...nd 1. 9 g. ; and for the writer, . 5 g. , 1. 4 g. And 1. 6 g. Thus the smaller the area the greater the probability that stimuli of low intensity will be perceived.
In a similar manner the relation of the pain threshold to the area of stimulation was investigated. The average values of the pain threshold, based upon 80 experiments on two observers, were: for 10 mm. , i. 4kilog. ; for 30 mm..

2. 8 kilog. ; for 90 mm. , 4. 4 kilog. ; and for 270 mm. , 6. 6 kilog. Thus the pain threshold increases with the area; but, Hke the tactile threshold, much more slowly than in direct proportion.
