Correction to: Nature Neuroscience https://doi.org/10.1038/nn956, published online 15 October 2002. Following publication of this article, the authors were alerted to an image duplication in Fig. 4, panels g and i. Due to the age of the article, the original confocal images cannot be retrieved to confirm or correct either panel. The authors acknowledge the error in the representative images and note the quantitation of multiple animals in Fig. 4k supports the key results.

eLife assessment This is an important study on how behavioral context affects decision making in the nematode C. elegans. Behavioral analyses at multiple time scales combined with genetic and neuronal manipulations revealed how arousal states affect decision making. The results and interpretations are convincing. This work will be of interest to both neuroscientists and ecologists.

Abstract Male/hermaphrodite species have arisen multiple times from a male/female ancestral state in nematodes, providing a model to study behavioral adaptations to different reproductive strategies. Here we examined the mating behaviors of male/female (gonochoristic) Caenorhabditis species in comparison to male/hermaphrodite (androdiecious) close relatives.
