The recovery processes of 72 out of the 269 aphasic patients studied in PART I were investigated longitudinally by means of following up the rate(and direction)of the change of each of the five factors obtained in PART I. Measrement was taken of the increase and decrease of the factor scores estimated for each patient at each of the successive re-testings. The length of the follow-up period ranged from one to 32 months after the initial evaluation. Each factor seemed to have its characteristic mode of change in time. Factor 1(the general factor of language behavior)had a tendency to exhibit subnormal scores in the majority of subjects at the initial evaluation, but to show a greatest possibility of improvement for a longest period of time(1.5 years since onset). The rest of the factors tended to be more variable in the kinds of subjects exhibiting subnormal scores as well as in the rate and degree of improvement. The clinical types of aphasia appeared to serve as a crutail variable in predicting the overall patterns of improvement of the five factors in individual patients. The finding seemed to give a further support for the neuro-physiological intetpretation of the five factors suggested in PART I. The necessity of increased specificity in our diagnostic and therapeutic procedures was emphasized, and the possible use of the factor analysis technique for this purpose was reiterated.
