TEC proposes that whenever there is a perception of a stimulus that has previously been integrated in an event file, this can affect actions. The activation of an event file follows a pattern-completion logic, meaning that the entire event file can be (re-)activated once a single feature of either a stimulus or a response is (re-)encountered. Hence, event files establish bindings between features specifying a stimulus and features specifying an action. to-be-produced events) are represented by features detailing a potential outcome and, for example, hand or finger movements used to execute a response. integrated) to achieve a coherent perception facilitating behavioural responses. These features are closely bound to one another (i.e. A, B, etc.) as well as subjective associations that may accompany a specific stimulus–response relation (i.e. italics or bold), colour and identity (e.g. Stimuli, such as letters, for example, may be coded by objective features, such as their shape (e.g. stimuli) are coded for by their constituting feature codes within a common format-the ‘event file’. actions) and perceived external events (i.e. TEC states that to-be-produced events (i.e. One of these is the theory of event coding (TEC) formulating a theoretical basis for action–perception interactions central for sensorimotor integration processes and cognitive control. It is well established that objective perception and action are intimately intertwined and strong theoretical frameworks have been put forward focusing on this link. In the current study, we challenge this view by showing how sensorimotor integration is modulated by objectively non-existent but still non-pathological perceptions. Exceptions are usually made for instances of mental illnesses, associated with delusions or hallucination. This common-sense assumption has dominated research to such a great extent that it seems counterintuitive that perceptual aspects lacking perceptual presence (that are non-veridical) affect our motor responses and behaviour in healthy humans. We continually perform actions driven by our perceptions, and it is commonly held that only objective changes of perceptual aspects in the ‘real’ world (that are veridical) can affect our behaviour. This article is part of a discussion meeting issue ‘Bridging senses: novel insights from synaesthesia’. Our results challenge common conceptions about the determinants of human behaviour but can be explained by well-established theoretical frameworks detailing the link between perception and action. Source localization analysis implicates activation within medial frontal cortices in the effect of how irrelevant non-veridical perceptions modulate behaviour. ERP analysis suggests that even though the examined peculiarities and experimental variations are perceptual in nature, it is not early-stage perceptual processes, but rather higher-order executive control processes linking perceptions to the appropriate motor response underlying this effect. Using electroencephalography, we determine whether early-stage perceptual processes (reflected by P1 and N1 event-related potential (ERP) components), or late-stage-integration processes (reflected by N2 component), underlie the effects of non-veridical perceptions on action control. non-veridical) but still non-pathological perceptions affect actions in healthy humans. Here, we demonstrate, using synaesthesia as a model condition (in N = 19 grapheme-colour synaesthetes), how objectively non-existent (i.e. Exceptions are generally only made for mental health disorders associated with delusions and hallucinations where behaviour may be triggered by the experience of objectively non-existent percepts. We continually perform actions that are driven by our perception and it is a commonly held view that only objectively perceived changes within the ‘real’ world affect behaviour.
