Perceptual Constancy
Our eyes deceive us when we look down railway tracks, but our brains do not. The rails appear to converge in the distance, but we know that the rails are parallel. We know that they are the same distance apart a mile down the track as they are where we are standing, so the brain says, “The tracks only appear to converge because they are distant.” But how does the brian know that the tracks are ...
متن کاملNon-uniform vowel normalization
A study of female-male differences in F F2: and F3 of var ious vowels within eight different languages revea ls univer sa l tendencies of departure f rom a simple uniform scaling. These have been quantified and adopted a s a basis for a vowel-category-specific normalization procedure which, on the average, reduces the female-male variance to one-half of that remaining after a simple uniform sca...
متن کاملPerceptual learning depends on perceptual constancy.
Perceptual learning refers to experience-induced improvements in the pick-up of information. Perceptual constancy describes the fact that, despite variable sensory input, perceptual representations typically correspond to stable properties of objects. Here, we show evidence of a strong link between perceptual learning and perceptual constancy: Perceptual learning depends on constancy-based perc...
متن کاملModeling Vowel Normalization and Sound Perception as Sequential Processes
This study constitutes the first attempt at combining vowel normalization procedures with the linguistic perception framework of Stochastic Optimality Theory [1] and the Gradual Learning Algorithm [2]. Virtual learners possessing different normalization procedures, and a control learner with no normalization, were trained to perceive Brazilian Portuguese and American English vowels. Our results...
متن کاملDynamic constancy as a basis for perceptual hierarchies.
Bateson's difference-based epistemology can be simulated by a Boolean network model. Bateson proposed that taking differences in differences would produce emergent hierarchies of knowledge. This study simulated Bateson's proposal by taking differences in differences in a Boolean model. The crucial result is that constancies in the dynamics of the flow of differences in the model (a) define perc...
