Perceiving and reacting to multidimensional objects creates so-called event files via feature binding. Bogon, Thomaschke, and Dreisbach provided the first evidence for the integration of the feature into such event files. However, their paradigm did not allow for differentiation between stimulus-stimulus and stimulus-response binding. This study used a classification task with many-to-one mappings to examine the integration of stimulus and response features independently. Experiment 1 used a pitch classification task. Participants had to respond with a left keypress to a low and a very low sine tone and with a right keypress to a high and very high sine tone. The four sine tones were presented for either a short or long duration, resulting in a total of eight stimuli. As an indicator of binding, we used partial repetition costs (better performance when both pitch/response and duration repeat or shift relative to partial repetitions). Results of Experiment 1 indicate stimulus-response binding and no stimulus-stimulus binding. In Experiment 2, instead of classifying the pitch of artificial sine tones, participants had to classify the type of musical instruments that produced the stimulus tones. Results replicated evidence for stimulus-response binding but also provided indications for stimulus-stimulus binding. Potential reasons for this result pattern and the relevance of duration in a musical context as one potential moderator of stimulus-stimulus bindings are discussed.
通过特征绑定来感知多维物体并对其做出反应会创建所谓的事件文件。博贡、托马施克和德雷斯巴赫首次提供了将特征整合到此类事件文件中的证据。然而，他们的范式无法区分刺激-刺激绑定和刺激-反应绑定。本研究使用了具有多对一映射的分类任务来独立检验刺激和反应特征的整合。实验1使用了音高分类任务。参与者必须在听到低音和极低的正弦音时按下左键，在听到高音和极高的正弦音时按下右键。这四种正弦音以短时长或长时长呈现，总共产生八种刺激。作为绑定的指标，我们使用了部分重复成本（当音高/反应和时长相对于部分重复都重复或变化时，表现更好）。实验1的结果表明存在刺激-反应绑定，但不存在刺激-刺激绑定。在实验2中，参与者不是对人工正弦音的音高进行分类，而是必须对产生刺激音的乐器类型进行分类。结果重复了刺激-反应绑定的证据，但也提供了刺激-刺激绑定的迹象。讨论了这种结果模式的潜在原因以及在音乐背景下时长作为刺激-刺激绑定的一个潜在调节因素的相关性。
