...Akihiro Itahara; Fumihiro Kano ABSTRACT Previous studies often inferred the focus of a bird's attention from its head movements because it provides important clues about their perception and cognition. However, it remains challenging to do so accurately, as the details of how they orient...

...José Monteagudo; Martin Egelhaaf; Jens Peter Lindemann ABSTRACT Flies are often observed to approach dark objects. To a naive observer they seem to pay selective attention to one out of several objects although previous research identified as a possible underlying mechanism a reflex-like fixation...

...Leonie Kirszenblat; Deniz Ertekin; Joseph Goodsell; Yanqiong Zhou; Paul J. Shaw; Bruno van Swinderen ABSTRACT Although sleep deprivation is known to impair attention in humans and other mammals, the underlying reasons are not well understood, and whether similar effects are present in non-mammalian...

... how males selectively direct their attention to make these assessments. Using Indian peafowl ( Pavo cristatus ) as a model system, we examined how males visually assess their competitors by continuously tracking the gaze of freely moving peacocks during the mating season. When assessing rivals...

... Directionality Flight path Sensory load Attention Bats (Chiroptera) are the most ecologically diverse group of mammals. With the exception of most bats in the order Pteropodidae, echolocation is the dominant sensory system for spatial orientation and foraging in these animals ( Griffin, 1958...

... defocused images of clutter do not mask perception of focused images for targets. Neural response synchronization may select a target to be the focus of attention, while desynchronization may impose inattention on the surroundings by defocusing perception of clutter. The formation of focused biosonar images...

... to perform matched tests to compare the ways fish and humans scan stationary visual scenes. In humans, visual search is seen as a doorway to cortical mechanisms of how attention is allocated. Fish lack a cortex and we therefore wondered whether archerfish would differ from humans in how they scan...

... selection may favor attention mechanisms allowing the choosing females to selectively and efficiently acquire relevant information from complex male display traits and, in turn, may favor male display traits that effectively capture and hold female attention. Using a miniaturized telemetric gaze-tracker, we...

...Linde Morawetz; Johannes Spaethe SUMMARY Mechanisms of spatial attention are used when the amount of gathered information exceeds processing capacity. Such mechanisms have been proposed in bees, but have not yet been experimentally demonstrated. We provide evidence that selective attention...

...Johannes Spaethe; Jürgen Tautz; Lars Chittka SUMMARY In humans, visual search tasks are commonly used to address the question of how visual attention is allocated in a specific task and how individuals search for a specific object (`target') among other objects (`distractors')that vary in number...

... models of conditioning include cognition-like concepts of attention or expectation which, consequently, seem also to apply to honeybees. Here, we first reproduce a blocking-like effect in an experimental design taken from the literature. We identify two confounding variables in that design...
