“…Additionally, the feature of length has not been examined as extensively as luminance in the neurophysiological literature, however these results suggest that it would be a fruitful area of further study [19]. Certainly many singleton features might make a task easier by making an object easier to detect or discriminate [15], and determining whether attention is stimulus-driven or goal-directed is necessary to determine the neurophysiological mechanisms of attention [19].…”

Can objects or events ever capture one's attention in a purely stimulus-driven manner? A recent review of the literature set out the criteria required to find stimulus-driven attentional capture independent of goal-directed influences, and concluded that no published study has satisfied that criteria. Here visual search experiments assessed whether an irrelevantly large object can capture attention. Capture of attention by this static visual feature was found. The results suggest that a large object can indeed capture attention in a stimulus-driven manner and independent of displaywide features of the task that might encourage a goal-directed bias for large items. It is concluded that these results are either consistent with the stimulus-driven criteria published previously or alternatively consistent with a flexible, goal-directed mechanism of saliency detection.

“…Neural afferent tuning curves bias nervous systems towards certain types of signals over others and thus could be seen to serve as an attention-like filtering process [16] albeit not one that achieves selective attention. In the cricket Teleogryllus commodus, for example, the ascending auditory interneurons (AN1) are not always perfectly tuned to the average frequency of male mating calls.…”

Attention is fundamentally important for sensory systems to focus on behaviourally relevant stimuli. It has therefore been an important field of study in human psychology and neuroscience. Primates, however, are not the only animals that might benefit from attention-like processes. Other animals, including insects, also have to use their senses and select one among many stimuli to forage, avoid predators and find mates. They have evolved different mechanisms to reduce the information processed by their brains to focus on only relevant stimuli. What are the mechanisms used by insects to selectively attend to visual and auditory stimuli? Do these attention-like mechanisms achieve the same functions as they do in primates? To investigate these questions, I use an established framework for investigating attention in non-human animals that proposes four fundamental components of attention: salience filters, competitive selection, top-down sensitivity control and working memory. I discuss evidence for each of these component processes in insects and compare the characteristics of these processes in insects to what we know from primates. Finally, I highlight important outstanding questions about insect attention that need to be addressed for us to understand the differences and similarities between vertebrate and insect attention.
