Experimental tests of visual competitive selective attention in insects. (a) Competing artificial flowers with the possibility of predation by ‘robotic spiders’ test selective attention of free-flying bumblebees to colour and shape during simultaneous tasks (after [34]). (b) Moving stripes in a cylindrical flight arena are used to test spatial attention and response to prior cuing in flies during tethered flight (after [33]). (c) Competing targets in different areas of the visual field are used during electrophysiological investigations into selective attention in dragonflies (after [28]). (d) Targets that differ in depth and shape compete for selective attention as measured by the saccades of tethered praying mantises (after [27]).
