The fitness consequences of age-dependent changes in cognitive abilities

该项目旨在调查入侵鱼类中与健康相关的话题。大大脑的进化表明，由于自然选择和性选择，聪明的人会有更多的后代。这个项目的目的是测试执行认知挑战任务的能力是否预示着生殖成功。此外，许多生活史特征显示出早年和晚年生活表现之间的权衡。该项目将测试这一预测，以了解年轻时认知表现高于平均水平的人，是否在年老时低于平均水平，即更快的“认知衰老”，或者是否有些人在一生中保持相对更聪明的状态。

This project aims to investigate health-related topics in invasive fish. The evolution of large brains suggests that smarter individuals have more offspring due to natural and sexual selection. This project aims to test if the ability to perform cognitively challenging tasks predicts reproductive success. In addition, many life history traits show a trade-off between early and late life performance. This project will test this prediction to see if individuals with above average cognitive performance when young are below average when old, that is faster 'cognitive senescence', or whether some individuals stay relatively smarter than others throughout their lives.
