Humans have to coordinate many different inputs to generate a goal-directed output. Although it seems trivial that we can execute most actions in our everyday life effortlessly - it is not. Several independent processes merge to produce seemingly trivial looking actions. In research on human action control, the processes of binding and retrieval have received increased interest in recent years. In this context, a unified account emerged that strives to specify binding and retrieval in action control (BRAC) over a range of related experimental phenomena and paradigms (Frings et al., 2020). In the first symposium, we take a broad look at research that demonstrates the far reach of action control. The interconnection between learning and action control processes is investigated in two talks regarding performance feedback and associative learning. The following talk is concerned with the role of action control in the auditory domain, specifically in music. The talk after this presents findings on the role of binding and retrieval processes in the context of task switching. The final talk looks at the neural correlates of action control. The contributions presented in both symposia underline the diversity of the research areas investigating human action control and highlight the prominent role of binding and retrieval processes for moving forward in understanding goal-directed human action.

As theories describing event file dynamics (Theory of Event Coding (TEC; Hommel et al. 2001), Binding and Retrieval in Action Control (BRAC; Frings et al. 2020)) aim to provide a comprehensive explanation of how the mind works, their principles should apply not only in the frequently studied situations of response selection, but also in other domains such as response inhibition. In this talk, the relevance of event file coding to response inhibition and its neural underpinnings will be illustrated using EEG data that have been examined using a wide range of analysis methods including network analysis and MVPA. Moreover, the influence of pre-trial dynamics as well as manipulations of the catecholaminergic system on event file coding in response inhibition was investigated. The results show that depending on the event file coding requirements different mechanisms are used to process stimulus features, and thus to inhibit responses successfully despite conflicting information, as reflected, for instance, in a seesaw-like relationship between the theta and alpha frequency bands. Thus, examining the dynamics of event files in response inhibition and their neural basis demonstrates the applicability of event file coding theories such as TEC and BRAC in different cognitive domains and offers a contribution to more sophisticated theory building integrating cognitive and neurophysiological elements.
