多个认知特征定义了蜜蜂的认知轴。蜜蜂采集者有两种不同的认知表型。慢速和快速的蜜蜂符合速度与准确度权衡的预测。这两种认知表型的行为和生活史特征有所不同。认知能力的个体间差异已在多种类群中广泛报道，并且最近被建模为速度与准确度权衡的广泛结果。这种权衡可能会导致不同的认知表型，而这反过来又可能与行为和生活史特征的差异相关。虽然越来越多的文献表明，某些认知和行为特征的表现确实存在共变，但必须在这些不同的水平上测量多种特征，以了解认知差异如何决定其他特征的变化。我们通过测量多种认知特征并确定这些特征是否以可用于定义认知轴的方式共变，测试了蜜蜂（Apis mellifera）是否存在不同的认知表型。我们的结果表明存在两种不同的认知表型，满足速度与准确性权衡的预测，因此与慢速蜜蜂相比，快速蜜蜂通过高联想学习、对新颖性的高度偏好和对方差的高度偏好来描述，并且这些差异在整个群体中是一致的。然后，我们通过测量这两种认知表型在几种行为和生活史特征中的表现来确定它们之间是否存在功能差异。我们发现，快速蜜蜂也有更多的护理行为，并在较早的年龄转变为觅食者，但我们没有发现它们的社会行为或生存有任何差异。我们讨论我们的结果对社会行为和生活节奏假设的可能影响。
HighlightsMultiple cognitive traits define a cognitive axis in honey bees.There are two distinct cognitive phenotypes among honey bee foragers.Slow and fast bees conform to the predictions of a speed–accuracy trade-off.The two cognitive phenotypes differ in their behaviour and life history traits.Interindividual variation in cognitive ability has been widely reported across a diverse array of taxa and has recently been modelled as a broad consequence of a speed–accuracy trade-off. This trade-off can result in alternative cognitive phenotypes, which in turn could be associated with differences in behavioural and life history traits. While a growing body of literature suggests that performance in certain cognitive and behavioural traits do covary, multiple traits must be measured at these different levels to understand how differences in cognition determine variation in other traits. We tested for the presence of distinct cognitive phenotypes in the honey bee, Apis mellifera, by measuring multiple cognitive traits and determining whether these traits covary in a manner that can be used to define a cognitive axis. Our results indicate the presence of two distinct cognitive phenotypes that meet the predictions of the speed–accuracy trade-off such that fast bees are described by high associative learning, high preference for novelty and high preference for variance, compared to slow bees, and that these differences are consistent across colonies. We then determined whether there were functional differences between these two cognitive phenotypes by measuring their performance in several behavioural and life history traits. We found that fast bees also engaged in more nursing behaviour and transitioned to becoming foragers at an earlier age but we detected no difference in their social behaviour or survival. We discuss our results in terms of their possible implications for social behaviour and the pace-of-life hypothesis.
