Discrimination of dynamic change and constancy over time by pigeons.
The detection of change over time is critical to the serial integration of reality. Three pigeons, in a same/different go/no-go discrimination, were rewarded for pecking at changing stimuli that oscillated back and forth in brightness over a specific range and not at constant, unchanging stimuli randomly selected from the same range. Experiment 1 tested their capacity to detect increasingly slo...
متن کاملSpace constancy vs. shape constancy.
The perceived distance between objects has been found to decrease over time in memory, demonstrating a partial failure of space constancy. Such mislocalization has been attributed to a generalized compression effect in memory. We confirmed this drift with a pair of remembered dot positions but did not find a compression of perceived distance when the space between the dots was filled with a con...

متن کاملSimulating Political Stability and Change in the Netherlands (1998-2002)
Agent-based models of political party competition in a multidimensional policy space have been developed in order to reflect adaptive learning by party leaders with very limited information feedback. The key assumption is that two categories of actors continually make decisions: voters choose which party to support and party leaders offer citizens a certain policy package. After reviewing the a...
متن کاملColor constancy, lightness constancy, and the articulation hypothesis.
The light that reaches the eye has a history. Its spectral distribution at each point of the retina depends on the illumination present in the scene, the spectral properties of surfaces it encounters on its path to the eye, and other factors (Nassau 1983). The human visual system assigns colors to surfaces. If the assigned color of a surface patch is (approximately) determined by the spectral p...
