The cost of limited attention in blue jays
Experiments with fish and birds suggest that animals are unable to simultaneously allocate sufficient attention to tasks such as the detection of an approaching predator while searching for cryptic prey. We quantified the effects of limited attention on performance in controlled laboratory settings and report here the first direct evidence that attending to a difficult central task simulating f...
متن کاملVisual search and attention in blue jays (Cyanocitta cristata): Associative cuing and sequential priming.
Visual search for complex natural targets requires focal attention, either cued by predictive stimulus associations or primed by a representation of the most recently detected target. Because both processes can focus visual attention, cuing and priming were compared in an operant search task to evaluate their relative impacts on performance and to determine the nature of their interaction in co...

15 صفحه اولVisual Detection of Cryptic Prey by Blue Jays (Cyanocitta cristata).
Blue jays learned to respond differentially to the presence or absence of Catocala moths in slides. This detection of the moths by the jays was affected by the background upon which the moth was placed and its body orientation, thus providing an objective measure of crypticity. These procedures are useful for the study of visual detection of prey.
متن کاملBlue jays, Cyanocitta cristata, devalue social information in uncertain environments
http://dx.doi.org/10.1016/j.anbehav.2015.11.015 0003-3472/© 2015 The Association for the Study of A Animals are selective about when to learn by observing others. Models predict that social information becomes less reliable in uncertain environments, and therefore animals should reduce their use of social information in these environments; however, these parameters are often difficult to manipu...
