Stochastic re-calibration: contextual effects on perceived tilt.
The human visual system exaggerates the difference between the tilts of adjacent lines or grating patches. In addition to this tilt illusion, we found that oblique flanks reduced acuity for small changes of tilt in the centre of the visual field. However, no flanks--regardless of their tilts--decreased sensitivity to contrast. Thus, the foveal tilt illusion should not be attributed to orientati...
متن کاملContextual effects on perceived three-dimensional shape
Binocular disparity is a powerful cue for the perception of depth. The accuracy with which observers can judge depth from disparity can, however, be very poor. This has been attributed to difficulties associated with the scaling of disparity to take account of distance (Johnston, 1991). We test potential strategies that could be used to improve this scaling. Using the depth-to-width ratio task ...
متن کاملNonparametric Stochastic Contextual Bandits
We analyze the K-armed bandit problem where the reward for each arm is a noisy realization based on an observed context under mild nonparametric assumptions. We attain tight results for top-arm identification and a sublinear regret of Õ ( T 1+D 2+D ) , whereD is the context dimension, for a modified UCB algorithm that is simple to implement (kNN-UCB). We then give global intrinsic dimension dep...
متن کاملContextual effects on the perceived health benefits of exercise: the exercise rank hypothesis.
Many accounts of social influences on exercise participation describe how people compare their behaviors to those of others. We develop and test a novel hypothesis, the exercise rank hypothesis, of how this comparison can occur. The exercise rank hypothesis, derived from evolutionary theory and the decision by sampling model of judgment, suggests that individuals' perceptions of the health bene...
متن کاملDynamic Re-calibration of Perceived Size in Fovea and Periphery through Predictable Size Changes
The same object produces quite distinct images in the cortical representation, depending on whether it is looked at foveally or with the periphery, yet some form of size constancy prevents us from experiencing objects inflating or deflating as we move our eyes. According to the prominent sensorimotor account of vision by O'Regan and Noë [1], we constantly learn to discount the predictable senso...
