摘要: Our trunks influence where we perform actions in space. Thus, trunk direction may define a region of space that is accorded special treatment by the attention system. We investigated conditions under which orientation bias for might be relevant healthy adults. Three experiments compared visual detection performance participants standing and walking on treadmill. Together, disambiguate relative contributions motor activity, load, cognitive load biases. In Experiment 1, biases (i.e., faster target targets front body midline) were observed both forward sideways conditions, but not conditions. 2, ruled out notion arose from increased activity; fact, was greatest when walked at an unusually slow pace. 3, directly with dual-task paradigm; influenced overall speed, only produced bias. These results suggest emerges during
