对昆虫选择性注意的研究通常使用单一平面上的刺激来研究。深度线索的重要性，如立体视差，是不太好理解。最近的神经生物学研究结果表明，螳螂的立体视中枢到周边视区的离心神经元连接，这表明注意力调节的可能性。为了测试这一点，我们调查了先前线索的差异是否会影响螳螂对3D目标的跟踪。我们给螳螂戴上3D眼镜，给它们一个提示，然后给它们两个3D刺激--一个高对比度的目标和一个对比度不同的干扰物。提示出现在目标或干扰物的一侧。我们改变了线索的视差，并测量了线索对头部扫视目标的概率的影响。我们的研究结果表明，相比无线索条件下，线索与交叉或未交叉的差距减少了头部扫视到一个单一的目标时，在屏幕的另一边。这些影响没有看到线索与零差距。不同视差线索的影响本身并没有显着差异，但交叉和非交叉的视差线索比零视差线索有更强的影响。我们的研究结果表明，螳螂的选择性注意的存在和位置的先验线索与线索差异的潜在影响。这进一步证明了昆虫类注意过程的复杂性。
Research on insect selective attention has typically investigated it using stimuli in a single plane. The importance of cues to depth, such as stereoscopic disparity, is less well understood. Recent findings on the neurobiology of mantis stereopsis demonstrated centrifugal neuronal connections from the central brain to peripheral optic areas, suggesting the possibility of attentional modulation. To test this, we investigated whether the disparity of a prior cue influences mantis tracking of 3D targets. We fitted mantises with 3D glasses and presented them with a cue, followed by two 3D stimuli – a high contrast target and a distractor with different contrasts. The cue appeared either on the side of the target or the distractor. We varied the disparity of the cue and measured the influence of the cue on the probability of head saccades to the target. Our results show that, compared to the uncued condition, cues with a crossed or an uncrossed disparity reduced head saccades to a single target when presented on the opposite side of the screen. These effects were not seen for cues with zero disparity. The effects of cues of different disparities did not themselves differ significantly, but crossed and uncrossed disparity cues had a stronger effect than zero disparity cues. Our results show that mantis selective attention is influenced by the presence and position of prior cues with a potential influence of cue disparity. This adds further evidence for the complexity of attention-like processes in insects.
