探索反射性联合注意力的研究报告称，干扰性社会信号（如他人的凝视或手的方向）比非生物方向性线索（如箭头）更能有效地捕捉注意力。然而，仍然未知的是，这些影响是在纯粹的空间或身体部位特定的参考框架中映射的。将中心的黑色注视点变为蓝色或橙子是实验受试者进行快速或快速运动（研究1中的扫视和研究2中的手指向）的命令性指令信号，同时忽略分散注意力的刺激（快速或快速定向凝视，手指向或箭头）。与指令线索方向不一致的凝视和指向手干扰分别损害了目标驱动的扫视和指向性能。这种模式的结果表明，反射性社会注意力不仅映射在空间，而且在身体部位的特定参考框架。
Studies exploring reflexive joint attention report that attention is more powerfully captured by interfering social signals (such as others' gaze or hand orientation) than by non-biological directional cues (such as an arrow). However, what remains unknown is whether these effects are mapped in purely spatial or in body-part specific reference frames. Changes of a central, black fixation point into blue or orange were the imperative instruction signal for the experimental subjects to make a leftward or a rightward movement (saccades in Study 1 and hand pointing in Study 2) while ignoring distracting stimuli (leftward or rightward oriented gaze, hand pointing or arrow). Gaze and pointing hand distracters that were directionally incongruent with the instruction cue impaired the goal-driven saccadic and pointing performance, respectively. This pattern of results indicates that reflexive social attention is mapped not only in spatial but also in body-part specific reference frames.
