Inhibitory ease--a personality type?

Measures of reactive, transmarginal and internal inhibition, inhibitory strength, extraversion (E) and neuroticism (N) were obtained from a sample of 25 Ss. A Principal Components analysis of the data disclosed factors which were identified tentatively as extinctive/reactive inhibition, transmarginal inhibition, and appetitive and aversive inhibitory strength. N loaded the transmarginal inhibition factor, and I(Introversion) the appetitive inhibitory strength factor. It is suggested that the role of E in appetitive CR extinction may be a function of the extent to which inhibitory strength is involved in inhibitory dynamism.
