However, in presence several orientations, can become inefficient strongly dependent on (Exp. 1). Search be even only 2 distractor orientations used those quite remote from (e.g. 20 degrees or 40 away, Exp. 2). among heterogeneous becomes more efficient item possessing categorical attribute such as steep, shallow 3), tilted left right 4), simply (Exps. 5 6).
