Changes in area affect figure–ground assignment in pigeons
A critical cue for figure-ground assignment in humans is area: smaller regions are more likely to be perceived as figures than are larger regions. To see if pigeons are similarly sensitive to this cue, we trained birds to report whether a target appeared on a colored figure or on a differently colored background. The initial training figure was either smaller than (Experiments 1 and 2) or the s...
متن کاملA System for Finding Changes in Colour
We acquire a great deal of information about the world about us by perceiving the colour of objects. We can manage without colour, but certain tasks can become rather difficult telling ripe from unripe fruits, or finding green tennis balls lost in grass, for example. Yet colour information is seldom used by the machine vision community, although, given the present state of image understanding t...
متن کاملColour changes in quasar light curves
The study of quasar variability has long been seen as a way to understanding the structure of the central engine of active galactic nuclei, and as a means of verifying the morphology of the standard model. Much work has already been done on the statistical properties of light curves monitored in one colour, and it is now possible to use these observations to test predictions of theoretical mode...
متن کاملStress-induced core temperature changes in pigeons (Columba livia)
Changes in body temperature are significant physiological consequences of stressful stimuli in mammals and birds. Pigeons (Columba livia) prosper in (potentially) stressful urban environments and are common subjects in neurobehavioral studies; however, the thermal responses to stress stimuli by pigeons are poorly known. Here, we describe acute changes in the telemetrically recorded celomatic (c...
متن کاملCombination of Colour Favoured and Colour
In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...
