Load lightening and negotiation over offspring care in cooperative breeders

Lightening the Load

Autism spectrum disorder (ASD) research portrays a mixed picture of attentional abilities with demonstrations of enhancements (e.g., superior visual search) and deficits (e.g., higher distractibility). Here we test a potential resolution derived from the Load Theory of Attention (e.g., Lavie, 2005). In Load Theory, distractor processing depends on the perceptual load of the task and as such can...

Partial brood care compensation by female breeders in response to experimental manipulation of alloparental care

Negotiation over offspring care?—a positive response to partner-provisioning rate in great tits

However, in empirical studies on biparental birds, there has been some inconsistency in the direction and extent of the response, and the mechanism behind it has so far been unclear. Parents could be responding directly to partner work rate or indi...
