Abstract:The theory of event coding claims that when an action and its sensory effect consistently happen in close temporal proximity, we will associate the action with that effect. This effect is called an action-effect. Nevertheless it is argued that this framework is not appropriate for all kinds of actions. Actions based on voluntary movements, called intention-based actions, and the actions in which people need to respond to a given stimuli, called stimulus-based actions, are controlled by different neural substrates. It is thought that the action-effects develop only in actions that are carried out voluntarily. Findings have demonstrated this with a single-key press movement. The present study investigated this effect with a more complex key movement sequence. The experiment consisted of three phases. The participants practiced two sequences in the first practice phase. The second practice phase made a difference between intention-based and stimulus-based actions. In this phase, tones were given to the participants after they pressed their sequence to create an action-effect. The test phase consisted of an congruent and incongruent block in which the tones were given before they needed to press their sequence. The tones were congruent or incongruent compared to the second practice phase. Results showed no difference between the congruent and incongruent group in stimulus-based actions nor in intention-based actions. The tone did not act as an action-effect in the intention-based group nor in the stimulus-based group.
