Abstract
  • The adaptive specialization hypothesis posits that differences in cognitive demands between sexes can arise in response to differential requirements to solve ecological problems. In this thesis, the túngara frog is considered due to behavioral differences between males and females observed during mate choice, possibly leading to the development of advanced cognitive abilities in females to allow for them to accurately assess males. A previous study found support for this hypothesis, with females having learned to associate a red cue with the exit of a maze, while males relied on inconsistent left or right (egocentric) cues. These experiments retested this hypothesis, eliminating egocentric cues and solely providing red and yellow visual cues. Males appeared to learn at an equivalent rate as females, although a preference for red cues over yellow cues emerged, and differences in errors seemed to hint that males were not learning as effectively as females.
