Search width as a predictor for Accuracy (a) and Total Search Time (b). On the basis of the Fourier analysis, we computed an approximation of participants’ modal time before changing direction on each axis, using their dominant frequency component. Dividing participant’s overall search time by the modal time before changing direction provided an estimate of the number of changes of direction To take into account the number of sweeps both up and down, 1 was added to the number of changes of direction made by each participant along their dominant axis (i.e. whether they were in the left-to-right or top-to-bottom search group) and the length of the axis being travelled across was divided by this figure. This provided a normalized search width in meters (m). Accuracy was the proportion of coins detected and Total Search Time indicates the total amount of time spent searching in seconds (s)
