This study aimed to clarify the functional differences between the use of the Japanese word for self watashi and an individual's name under the Implicit Relational Assessment Procedure (IRAP). Fifty-seven native Japanese speakers participated in the study. Each participant completed the Japanese version of the Rosenberg Self-Esteem Scale (RSES-J) and two IRAPs (I-IRAP and name-IRAP). IRAPs with two labels (watashi denoting “I” or [name] or “others”) and two targets (positive or negative words) were used. One-way repeated-measures analysis of variance (ANOVA) tests yielded significant main effects for the IRAPs. Bonferroni post hoc tests indicated that the effects for the name-positive trial type differed significantly from that of the three other trial types; there were no significant differences between the remaining trial types. However, I-IRAP trials differed significantly from other positive/negative trial types. Only the name-positive IRAP trial type correlated positively with the RSES-J score. A mixed-model 2 (IRAP; I or Name) × 4 (four trials) ANOVA showed no main effects or significant interaction effects. Steiger's Z showed a correlation between the name-positive trial type and RSES-J scores, and the I-positive trial type did not show a significant difference from RSES-J scores. The results indicate that the single-trial-type-dominance effect only occurred in the name-IRAP.
