Unravelling cross-recurrence: coupling across timescales

We present an extension of cross-recurrence analysis for dual gaze analysis which is suited for complex situations where for instance the objects of interest are not all visible at all times or when stimulus exploration is not homogeneous. The typicical situation is a visual stimulus that is scrolled or that is explored sequentially. We use a recurrence simulation to illustrate how to measure the actual coupling between behavior streams without biases introduced by the complexity of the situation. Our method takes into account underlying random baselines to compute an unbiased version of the coupling.
