Past work has shown that cued manual responses in visuo-identity tasks bind to irrelevant stimulus features, present at the time these responses were executed (prime trial). These response bindings manifested their existence via impacts on later related processing (probe trial). Here, we extended this prior research by showing that response binding is likely a pervasive processing characteristic. We saw that uncertain prime-trial responses (i.e., free-choice, forced-choice) did bind to the relevant "location" feature of the prime stimulus in a visuospatial task (i.e., R-L binding). Overall, R-L binding evidence was better for within-hand than for between-hand probe-trial finger competitions and better for probe trial response selection preferences than for their reaction time (RT) data. R-L binding evidence was entirely absent, however, for forced-choice probe trials. Evidence that the prime response binds to irrelevant prime display features (i.e., prime stimulus identity [R-I binding]) was virtually absent. Other results indicated that R-I likely exists, but that its probe-trial manifestation is prevented by the involvement of R-L binding. Response binding impacts on later processing should be considered when interpreting RT data. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
过去的研究表明，视觉识别任务中的提示手动反应会与执行这些反应时（启动试验）出现的无关刺激特征相绑定。这些反应绑定通过对后续相关加工过程（探测试验）的影响来体现其存在。在此，我们扩展了先前的这项研究，表明反应绑定可能是一种普遍存在的加工特征。我们发现，在视觉空间任务中，不确定的启动试验反应（即自由选择、强制选择）确实会与启动刺激的相关“位置”特征相绑定（即R-L绑定）。总体而言，R-L绑定证据在同一只手内的探测试验手指竞争中比在不同手之间的情况更好，在探测试验反应选择偏好方面比在其反应时（RT）数据方面更好。然而，对于强制选择探测试验，完全不存在R-L绑定证据。启动反应与无关启动显示特征相绑定（即启动刺激身份[R-I绑定]）的证据实际上也不存在。其他结果表明，R-I可能存在，但其在探测试验中的表现受到R-L绑定的影响而被阻止。在解释RT数据时，应考虑反应绑定对后续加工过程的影响。（PsycINFO数据库记录（c）2019美国心理学会，保留所有权利）
