Levels of in-role and extrarole performance were experimentally manipulated in a 3 × 2 within-subjects design. Dimensions capturing both in-role and extrarole behaviors (i.e., citizenship behaviors directed toward other individuals) strongly influenced various measures of rater search strategies as well as the ratings given by 116 supervisors evaluating secretarial performance. Furthermore, as predicted by D. W. Organ (1990), dimension ratings assigned to ratees with high levels of extrarole behavior displayed significantly more halo than ratings given to ratees with neutral levels of extrarole behavior. Tests for the effects of level of extrarole behavior on 2 measures of rater accuracy produced contradictory results. Implications are discussed.
