IKENBERRY AND SHUTT: DIRECTION OF SOUND. 13 
number of judgments locating the sound too far in front was 
greater when one ear was closed than when both were open. In 
both cases, however, the tendency was to locate the sounds too far 
back. 
By arranging the judgments recorded in front and back of point 
25 we have this set of figures:

The number of correct judgments was nearly the same in both 
positions. That of those locating the sound too far back was the 
larger when the experimenter was in front of the subject. Judg- 
ments locating it too far in front prevailed when the experimenter 
was back of him. The whole number of judgments locating the 
sound back of the point 25, is larger than that of those locating it 
in front of that point. This fact indicates a general tendency to 
locate sounds too far back. 
The supposed location of the sounds made at points o and 50 
varied so much that a separate arrangement of them is required. 
The table below gives a summary of the supposed locations. The 
columns marked C contain the correct judgments. Those marked 
with an interrogation point show how often the subjects were in 
doubt whether the sound was in front of or behind them. Columns 
with an X at the top indicate the number of times sounds located 
in front of the subject were supposed to be behind him and wece 
versa. Rand L mean that errors were made respectively toward 
the right and left.
