“…Instead, it is sufficient to note two points of contention, and these points are not controversial in themselves. First, the claim of male superiority on spatial tasks finds experimental support only from a restricted group of tests, notably the Rod and Frame Task (Allen & Hogeland, 1978; Hyde, Geiringer, & Yen, 1975; Linn & Peterson, 1985), the Water Level Task (Beatty & Duncan, 1990; Goldbeck, 1986; Liben & Goldbeck, 1984; Linn & Peterson, 1985, Thomas, Jamison, & Hummel, 1973), and a variety of mental rotation tasks (Bryden, George, & Inch, 1990; Casey & Braebeck, 1990; Cochran & Wheatley, 1989; Gouchie & Kimura, 1991; Kail & Park, 1990; Lord, 1987; Mann, Sasanuma, Sakuma, & Masaki, 1990). While these tasks provide the strongest evidence for a male advantage, the advantage is by no means universal, and is subject to a variety of qualifications (Byrd et al, 1990; Corballis & Sergent, 1989; Gilger & Ho, 1989; Liben & Goldbeck, 1984; Kail, Pellegrino, & Carter, 1980; Kail, Carter, & Pellegrino, 1979; Olson, Eliot, & Hardy, 1988).…”
