Search speed to predict Accuracy and Total Search Time for left-to-right participants on the x-axis. On the basis of the Fourier analysis, we computed an approximation of participants’ modal time before changing direction in seconds (s) on each axis, using their dominant frequency component. By dividing the modal time before changing direction by the next most commonly occurring time before changing direction we computed the variability in time before changing direction in seconds (s). Accuracy was the proportion of coins detected and Total Search Time indicates the total amount of time spent searching in seconds (s). Figure 6 shows the modal time before changing direction (a) and the variability in time before changing direction (b) to predict Accuracy, plus the modal time before changing direction (c) and the variability in time before changing direction (d) to predict Total Search time. Note: lines of fit are shown when a statistically significant relationship is present
