Abstract：The kinaesthetic after-effects of 143 subjects were determined with twoinspection bars, one of which was narrower, the other was wider than thetestblock. According to the value of the after-effect induced by the narrowinspection bar and that by the wide one was positive or negative and thealgebraic sum of N+B, KAE fell into seven types. The neurotypes of someof the subjects were also estimated with the method used. by the Teplovianschool. The result shows that the value of the KAE of the more inhibitablesubjects tend to be negative, and that of the more excitable subjects positive.The results of GE test, reminiscence experiment and weight suggestion testall show that reducers are mostly extraverts, and augmenters mostlyintroverts. The authors have followed the change of the KAE of a subjectunder different conditions, the consistency of his type of KAE was observed,The procedure of KAE determination has been simplified. The KAE thusdetermined makes no difference with that determined with the method previouslyused. Both the consistency of the types of KAE and its simplified procedurecreate favorable conditions for KAE to be used as an index for extraversion-introversion diagnosis.
