... Twenty-four studies of nonpathological personality variables have been conducted to date (see Haslam & Kim, in press), and most favor the dimensional view. Taxonic findings were obtained for only seven variables (29% of the total), these exceptions being sexual orientation (Gangestad, Bailey, & Martin, 2000), self-monitoring (Gangestad & Snyder, 1985), infant reactivity (Woodward, Lenzenweger, Kagan, Snidman, & Arcus, 2000), hypnotic susceptibility (Oakman & Woody, 1996), type A (Strube, 1989), and certain response styles (Strong, Greene, & Schinka, 2000). Three studies of broad personality dimensions such as the FFM traits (Arnau, Green, & Tubre, 1999;Green, Arnau, & Gleaves, 1999) and Jung's preferences (e.g., feeling vs. thinking; Arnau, Green, Rosen, Gleaves, & Melancon, in press) have consistently supported their dimensionality, and three studies of personality characteristics conceptualized as diatheses (hypomanic temperament, Meyer & Keller, in press; anxiety susceptibility, Taylor, Rabian, & Fedoroff, 1999; and vulnerability to alcoholism, Knowles, 1989) have also yielded nontaxonic findings. ...
