对刺激的反应导致刺激-反应（S-R）关联的形成，这种关联允许刺激随后自动触发相关反应。最近的一项研究表明，S-R关联不仅是通过主动任务执行建立的，而且还通过同时呈现刺激和口头代码来表示在没有自己行动的情况下的反应[Pfeuffer et al.] （Journal of Experimental Psychology: Human Perception and Performance 43:328-347, 2017）。本研究采用项目特异性启动范式，通过对同一刺激物的不同知觉形式的S-R联想是否被检索，来研究基于任务执行和言语编码形成的S-R联想的刺激部分是抽象的还是具体的。在刺激的启动和探测实例之间，其格式从图像转换为文字，反之亦然。我们发现，无论刺激是由任务执行还是语言编码启动的，当S-R映射在刺激的启动和探测实例之间切换而不是重复时，表现都会受到损害。即使刺激格式转换，启动S-R映射也会影响探针的表现，这表明刺激在基于任务执行和言语编码的S-R关联中都以抽象形式呈现。此外，我们发现以相同的格式而不是不同的格式启动和探测的刺激对表现没有好处，这表明刺激没有以特定的格式额外呈现。总的来说，我们的研究结果证明了自动化行为的适应性，并表明抽象刺激表征允许S-R关联在知觉上不同的刺激格式中进行推广。
Responding to stimuli leads to the formation of stimulus–response (S–R) associations that allow stimuli to subsequently automatically trigger associated responses. A recent study has shown that S–R associations are established not only by active task execution, but also by the simultaneous presentation of stimuli and verbal codes denoting responses in the absence of own action [Pfeuffer et al. (Journal of Experimental Psychology: Human Perception and Performance 43:328–347, 2017)]. Here, we used an item-specific priming paradigm to investigate whether the stimulus part of S–R associations formed based on task execution and verbal codes is represented in abstract or specific format by examining whether S–R associations are retrieved for perceptually different forms of the same stimulus or not. Between the prime and probe instance of a stimulus, its format switched from image to word or vice versa. We found that, irrespective of whether stimuli were primed by task execution or verbal coding, performance was impaired when S–R mappings switched rather than repeated between the prime and probe instance of a stimulus. The finding that prime S–R mappings affected probe performance even when stimulus format switched indicates that stimuli were represented in abstract form in S–R association based on both task execution and verbal coding. Furthermore, we found no performance benefits for stimuli primed and probed in the same format rather than different formats, suggesting that stimuli were not additionally represented in specific format. Overall, our findings demonstrate the adaptability of automatized behaviors and indicate that abstract stimulus representations allow S–R associations to generalize across perceptually different stimulus formats.
