Towards measuring the impact of attention

Picture of the setup we used to assess the EEG characteristics of each of the attention types.

“Attention” is a generic word which according to the model of van Zomeren and Brouwer (1994) encompasses alertness and sustained attentions, referring to the intensity of attention (i.e., strength), as well as selective and divided attentions, referring to its selectivity (i.e., amount of monitored information). BCI literature indicates an influence of both users’ attention traits and states (i.e., respectively stable and unstable attentional characteristics) on the ability to control a BCI. Though the types of attention involved remain unclear. Therefore, assessing which types of attention are involved during BCI use might provide information to improve BCI usability. Before testing this hypothesis, we first needed to assess if the different types of attention are recognizable using EEG (see picture of our setup.)
