word was understood as _red_.]

The total number of different words elicited in response to any
stimulus word is limited, varying from two hundred and eighty words in
response to _anger_ to seventy-two words in response to _needle_.
Furthermore, for the great majority of subjects the limits are still
narrower; to take a striking instance, in response to _dark_ eight
hundred subjects gave one or another of the following seven words:
_light, night, black, color, room, bright, gloomy;_ while only two
hundred gave reactions other than these words; and only seventy
subjects, out of the total number of one thousand, gave reactions
which were not given by any other subject.

If any record obtained by this method be examined by referring to the
frequency tables, the reactions contained in it will fall into two
classes: the _common_ reactions, those which are to be found in
the tables, and the _individual_ reactions, those which are not
to be found in the tables. For the sake of accuracy, any reaction word
which is not found in the table in its identical form, but which is a
grammatical variant of a word found there, may be classed as

_doubtful_.

The value of any reaction may be expressed by the figure representing
the percentage of subjects who gave it. Thus the reaction,
_table--chair_, which was given by two hundred and sixty-seven
out of the total of our one thousand subjects, possesses a value of
26.7 per cent. The significance of this value from the clinical
standpoint will be discussed later.
