Ideomotor Theory: Basics and its contribution to explaining multitasking problems.
How do humans select an action? Ideomotor Theory, dating back to 19th century philosophers, claims that action are selected by anticipations of their consequences, that is, their action effects. In the first part of my talk, I will introduce this idea and provide an overview on the available experimental evidence from single-task studies.
However, in many if not all situations, humans do not only work on a single-task, but are engaged in several tasks at the same time, that is, they are multitasking. Thus, it is only consequent to ask: How can Ideomotor Theory can be applied to such situations? I will first, sketch the basic idea how this might be done. I will then continue with providing experimental evidence for this idea from several lines of my own research. I will finish the talk by considering recent theoretical developments and by outlining emerging questions that might guide future research.
