Of direct relevance to the present study is the theory of affective meaning propounded by Osgood. Two hypotheses were tested. According to a ＂magnitude＂ hypothesis, affective dimensions （each of evaluation, potency, and activity taken separately） differ in their magnitude across pronouns I, My, Me, and They. A ＂structural＂ hypothesis stated that the affective dimensions yield latent factors across （the generality） and within （the concept-scale interaction） the pronoun concepts. Repeated-measures analysis of variance （1-way ANOVA） and confirmatory factor analysis were employed to process data. It was found that each of the evaluation and potency measures yield a significant magnitude change across the pronouns, but there was indicated no significant change across the pronouns with respect to the activity dimension. Therewith, the pronoun My gained a salient value and the pronoun They the smallest value. Using confirmatory factor analysis five models were tested. Among them one model was good fit to the data. It engaged a four-factor solution resulted in that four pronouns are latent affective distinct but related factors and the evaluation, potency, and activity are their indicators.展开更多
