Highly responsive fish tend to proportionally use their left side more when compared to those individuals that display a less responsive behavior towards a vibrating stimulus. “# of fish” includes both individuals that only approach the device and then swim away and highly responsive fish that circle around the device. “Turns” counts the behavior exclusively of the highly responsive fish that circle the device. It would appear that highly motivated fish enhance their left-sidedness in their foraging behavior when responding with VAB, except perhaps in Pachón cave population.
