Stimuli and responses are assumed to be bound together into a common episodic representation, referred to as an event file or a stimulus-response (S-R) episode. Repeating any features of this episode triggers the retrieval of the whole event file, which impairs performance if the retrieved information does not match current processing requirements, resulting in partial repetition costs (PRCs). According to event segmentation theory, events are organized by different factors, such as causal connection, temporal information, spatial location, and subjective goal (Zacks, 2020). In a series of experiments, we used temporal organisation factors implemented by temporal adverbials or physical intervals to investigate this segmentation role in the formation of S-R episodes and the likelihood of retrieval. We assumed that the after-effects of stimulus-response binding are smaller – visible in smaller PRCs – after temporal factors that indicate longer periods compared to temporal factors that indicate shorter periods. To test this, we employed a narrative version of the S1R1-S2R2 task and systematically varied either the interval between S1 and R1 trigger (Go Signal for response) or the interval between R1 and S2. For temporal adverbials (“after a while” vs. “immediately after”), we found no evidence of a segmentation role as indicated in PRCs. However, physical cues implemented with response stimulus intervals (RSIs) manipulated across three levels (500 ms, 1,500 ms, 5,000 ms) between R1 and S2 supported segmentation and reduced the after-effects of stimulus-response binding after long as compared with short RSIs.
