ABSTRACT

Individuals show marked and characteristic differences in the reactions they give to a suitably selected list of words.

Provided the mean values of several tests are taken and that these tests do not extend over too long a period individuals correlate with themselves much more highly than they do with each other.

The most probable values of the correlations of individuals with themselves and with each other may be taken as approximately -{--65 and +-15 respectively, for a list of words of the kind here used. More extensive investigations could, if necessary, enable us to fix these values precisely, to determine the corresponding frequency distributions and thus to render future problems dealt with on these lines amenable to strict mathematical treatment,

These facts should enable us to determine whether certain tracts of experience ever become completely split off from the principal mass, and whether mental conditions which appear at first sight to differ toto calo from each other are in reality determined by identically the same aggregate of experiences of which different aspects are thus expressed, or whether they proceed from aggregates so discrete and so independent of one another as to warrant our describing the resultant states as genuinely different personalities. They may also throw considerable light on various questions concerning the permanence and liability to disturbance of the affective tone concomitant to the experiences of an individual mind.
