Experimental evidence for offspring learning in parent-offspring communication.
The offspring of birds and mammals solicit food from their parents by a combination of movements and vocalizations that have come to be known collectively as 'begging'. Recently, begging has most often been viewed as an honest signal of offspring need. Yet, if offspring learn to adjust their begging efforts to the level that rewards them most, begging intensities may also reflect offsprings' pa...
متن کاملCommunication in vertical markets: Experimental evidence
When an upstreammonopolist supplies several competing downstream firms, it may fail to monopolize the market because it is unable to commit not to behave opportunistically. We build on previous experimental studies of this well-known commitment problem by introducing communication. Allowing the upstream firm to chat privately with each downstream firm reduces total offered quantity from near th...
متن کامل1 Trust , Communication and Contracts : Experimental Evidence
We introduce opportunities for pre-play communication and to enter binding or non-binding contracts in trust games, and find (a) communication increases trusting and trustworthiness, (b) contracts are unnecessary for trusting and trustworthy behaviors and are eschewed by many players, (c) more trusting leads to higher earnings, and (d) both trustors and trustees favor “fair and efficient” propo...
متن کاملP15: Hippocampus-Neocortical Communication in Learning
The hippocampus is located in the medial temporal lobe and is a part of the forebrain. It plays a critical role in formation of declared memories. The hippocampus is banana­-shaped and communicates with all parts of neocortex. Reptiles and birds have structures like hippocampus that potentially serve as navigation functions. During the mammalian evolution, the neocortex has a large expansio...
متن کاملExperimental evidence for interspecific directional selection on moth pheromone communication.
The chemical composition of the sexual communication signals of female moths is thought to be under strong stabilizing selection, because females that produce atypical pheromone blends suffer lower success in finding mates. This intraspecific selection pressure cannot explain the high diversity of moth pheromone blends found in nature. We conducted experiments to determine whether communication...
