  In cognitive neuroscience the sense of agency is defined as the as the
experience of controlling ones own actions and, through this control, affecting
the external world. At CHI 2012 I presented a paper entitled I did that!
Measuring Users Experience of Agency in their own Actions [1]. This extended
abstract draws heavily on that paper, which described an implicit measure
called intentional binding. This measure, developed by researchers in cognitive
neuroscience, has been shown to provide a robust implicit measure for the sense
of agency. My interest in intentional binding stemmed from prior HCI
literature, (e.g. the work of Shneiderman) which emphasises the importance of
the sense of control in human-computer interactions. The key question behind
the CHI 2012 paper was: can we apply intention binding to provide an implicit
measure for the experience of control in human-computer interactions? In
investigating this question, replication was a key element of the experimental
process.
