Evolved Simulated Agents Exhibit Size Constancy Abilities in Solving an Online Size Discrimination Task
We describe some Artificial Life simulations in which a situated model agent controlled by a feed-forward neural network has to solve a simple categorization task involving size constancy abilities in an online fashion. The results show that even a simple neural controller without internal recurrent dynamics is capable of solving a non-trivial size categorization task by exploiting the dynamica...
متن کاملSize matters: Perceived depth magnitude varies with stimulus height
Both the upper and lower disparity limits for stereopsis vary with the size of the targets. Recently, Tsirlin, Wilcox, and Allison (2012) suggested that perceived depth magnitude from stereopsis might also depend on the vertical extent of a stimulus. To test this hypothesis we compared apparent depth in small discs to depth in long bars with equivalent width and disparity. We used three estimat...

Charles Darwin when developing his theory of evolution. And a new study of work on the islands' marine iguanas may help throw some more light on the evolution of body size within these populations. Body size is one of the most important traits of organisms and allows predictions of an individual's morphology, physiology, behaviour and life history. However, explaining the evolution of such comp...
متن کاملSize matters: effects of stimulus size, duration and eccentricity on the visual gamma-band response.
OBJECTIVE The effects of stimulus size, duration and eccentricity on the visual gamma-band response (GBR) in human EEG were investigated and compared to visual evoked potentials (VEPs) in order to differentiate in future (and past) experiments whether changes in GBRs are due to stimulus-related (exogenous) or cognitive effects. METHODS EEG was recorded from 23 subjects while they performed a ...
متن کاملMatters of Size
Size does matter. At least that’s what the tagline of the movie Godzilla claims (one of the many renditions of the franchise). A quick glance at the great beasts of our past—dinosaurs, marine animals, snakes, why even disturbingly massive dragonflies, scorpions and camels—would make it appear as if increased body size conferred some sort of advantage then. Yet biologists concur that overall, th...
