In order to test whether or not instructions specifying the stimulus-response (S-R) mappings for a new task suffice to create bindings between specified stimulus and response features, we developed a dual task paradigm of the ABBA type in which participants saw new S-R instructions for the A-task in the beginning of each trial. Immediately after the A-task instructions, participants had to perform a logically independent B-task. The imperative stimulus for the A-task was presented after the B-task had been executed. The present data show that the instructed S-R mappings influence performance on the embedded B-task, even when they (1) have never been practiced, and (2) are irrelevant with respect to the B-task. These results imply that instructions can induce bindings between S- and R-features without prior execution of the task at hand.
为了测试指定新任务刺激-反应（S-R）映射的指令是否足以在指定的刺激和反应特征之间建立绑定，我们开发了一种ABBA类型的双重任务范式，在每次试验开始时，参与者会看到针对A任务的新S-R指令。在A任务指令之后，参与者必须立即执行一个逻辑上独立的B任务。在执行完B任务之后，会呈现A任务的命令性刺激。目前的数据表明，即使（1）从未练习过，且（2）与B任务无关，所指示的S-R映射仍会影响嵌入式B任务的表现。这些结果意味着，指令可以在无需事先执行手头任务的情况下，诱导S特征和R特征之间的绑定。
