The results of these orientation tests upon normal individuals were as
follows:
The normal individuals examined almost without exception visualized clearly
before and during speech. Sometimes this visualization was very marked in
detail and resulted in emotional responses, such as pleasures, etc.
From the above two sets of figures were thus obtained a fair norm of
visualization for ordinary individuals; and in comparison a marked variation
from this in stutterers. This data therefore warranted the tentative
conclusion that stutterers have a loss or diminished power of visualization.
This assertion may seem a little more than is warranted by such meagre data
and perhaps would be better revised pending further data into the following:
As compared with the normal, stutterers show a weakness in visualization.
