The following table shows for the several groups of reproductions 
the arithmetical average, the median and the average difference of 
the reaction-times of those experiments that resulted into a total or 
a partial recognition of the original figures.

An inaccurate reproduction made in the interval lengthens the 
recognition time in proportion as it differs from the original figure. 
M. reports only one case, in which recognition follows later on in 
spite of an inaccurate memory-image. We are, therefore, not enabled 
to publish any data illustrating the influence of a preceding false 
recognition upon the duration of the subsequent recognizing process. 
Whereas, on the one hand, an inaccurate reproduction occasions 
a slowing of the reaction, on the other hand an accurate repro- 
duction reveals itself in a quickened process. This is clearly demon- 
strated in the following table. It comprises the data regarding the 
recognition time, obtained after an accurate reproduction in the 
interval, by the side of those obtained after a series of control-tests, 
in which the interval between the impression and the recognition 
was the same, but without the pre-existence of a reproduction.
