Intentional Binding as a Function of Action-Effect Interval and Semantic Relatedness
Summary:
Voluntary actions and their sensory effects are perceived closer in time; a phenomenon known as intentional binding (IB). Most up-to-date studies have examined IB employing one-modality action effects, mostly abstract, yet everyday life actions produce multisensory, informationally rich effects. Recently, Thanopoulos, Psarou, and Vatakis (2018) used naturalistic multisensory stimuli as action outcomes and showed that IB occurs when voluntary actions and their effects hold an inherent causal link from everyday experience. Given the short action-effect interval used in Thanopoulos & Vatakis’s study (250ms; as in the majority of IB studies), in our first experiment, we manipulated this interval in order to investigate the limits of maintenance of IB in causal multisensory events. Using the same naturalistic stimuli and the same setup with Thanopoulos and Vatakis, we tested the participants in conditions varying in action intentionality and temporal predictability of the effect for intervals of 250, 800, 1000, and 1250ms using a simultaneity judgment (SJ) task. Further, given the use of a multisensory effect, the induction of IB may be affected by potential crossmodal binding rivalries. Particularly, the unity assumption might cause temporal stimulus shifts in order to reinforce a unified percept, possibly interacting with the temporal shift towards the action, as predicted by IB. Thus, in our second experiment, we investigated how strongly unified multisensory action effects can affect the IB phenomenon, using the same causal sequence of events and procedure as in Experiment 1 and varying the semantic content of the presentations. In our first experiment, the audiovisual pair was perceived earlier regardless of the presence of a voluntary action for intervals up to 1000ms, with the shifts becoming larger as the interval increased, revealing strong temporal binding. In our second experiment, only visual effects were perceived earlier, regardless of their congruency with the auditory stimulus or the presence of a voluntary action. Both results underline the strong influence of causal relations between our stimuli, that were necesssary for the temporal shifts to occur and clearly οvercame the effects of intention.
