自由飞行蜜蜂对静止目标形状和颜色的综合识别能力

研究了蜜蜂对相同颜色和不同颜色目标图对的形状以及颜色的综合识别能力实验过程中,蜜蜂始终处于自由飞行状态.做为刺激目标使用的图对分别有相同颜色不同几何形状、相同颜色不同拓扑结构和不同颜色几何形状三组.主要结果有三点:(1)在相同颜色的条件下,蜜蜂可以分辨出图形的几何形状,并且识别能力与图对的相似程度成反比(2)在刺激图形为环形时,蜜蜂对图形平均亮度敏感;在平均亮度相同的情况下,对环形细节变和尺寸大小不敏感.(3)在不同颜色不同几何形状的刺激条件下.蜜蜂视觉信息加工过程中颜色因素会抑制几何形状因素而起主要作用.这三个结果可以视为深入研究颜色加工通道和几何形状加工通道之间内在关系的基础.

THE COMPREHENSIVE ABILITY FOR RECOGNIZING SHAPE AND COLOUR OF THE STANDSTILL VISUAL TARGET-PAIRS IN FREE FLYING HONEYBEE

The comprehensive ability of honebee for recognizing shape and colour of the standstill visual target -pairs was investigated.The experiments were done under the conditions of free flight of the honeybees. The main results were described as follows:1. Under the conditions of same colour, the bee can distinguish the shapes of a target-pair, and this recognizing ability is inversely proportional to the shapes' similarity of the target - pair.2. The bee is sensitive to the difference of average luminosity of the visual patterns (the positive figure of the pairs), but not sensitive to the size of them if their shapes and average luminosity keep the same.3. The colour information should be a main factor which inhibits shape information in the bee's visual information processing system under the conditions of the target -pairs having both different colours and different shapes.
