Familiarity Facilitates Social Learning of Foraging Behaviour in the Guppy
Previous studies have shown that guppies, Poecilia reticulata, can learn the route to a food source by shoaling with knowledgeable conspecifics, and prefer to shoal with experienced foragers and familiar fish. We tested the hypothesis that guppies would learn more effectively from (1) familiar than unfamiliar demonstrators and (2) well-trained than poorly trained demonstrators. Demonstrator fis...
متن کاملMechanisms underlying shoal composition in the Trinidadian guppy, Poecilia reticulata
Free-ranging groups are frequently assorted by phenotypic characters. However, very little is known about the underlying processes that determine this structuring. In this study, we investigate the mechanisms underlying the phenotypic composition of shoals of guppies (Poecilia reticulata) in a high-predation stream in Trinidad’s Northern Mountain Range. We collected 57 entire wild shoals, which...

In this way, conforming to a reliable source boosts recognition performance but co...

The effects of Asch-type conformity were empirically tested on central actors and peripheral actors in each group using a culturally appropriate version of Asch’s test. Findings show that central actors...
