ABSTRACT
In author's very heterogeneous material there is undoubtedly a relation between incorrect reproduction and prolonged reaction-time, and it shows itself in such a way that disturbances of reproduction chiefly occur with prolonged reaction-times but also partly following these. Furthermore, the association that is afterwards incorrectly reproduced has on average twice as many complex-signs as the correctly reproduced one. From this it follows that the complex-characteristics tend to be grouped around certain associations. Without analyzing these one cannot see where the relationships between these greatly varying complexcharacteristics originate. For small series of numbers people therefore have to use the arithmetical mean. The most obvious method of comparison would be simply to compare the arithmetical mean of the times of the incorrectly reproduced associations with the arithmetical mean of all the times or of all the remaining times.
