Subjective randomness and natural scene statistics.
Accounts of subjective randomness suggest that people consider a stimulus random when they cannot detect any regularities characterizing the structure of that stimulus. We explored the possibility that the regularities people detect are shaped by the statistics of their natural environment. We did this by testing the hypothesis that people's perception of randomness in two-dimensional binary ar...
متن کاملNatural auditory scene statistics shapes human spatial hearing.
Human perception, cognition, and action are laced with seemingly arbitrary mappings. In particular, sound has a strong spatial connotation: Sounds are high and low, melodies rise and fall, and pitch systematically biases perceived sound elevation. The origins of such mappings are unknown. Are they the result of physiological constraints, do they reflect natural environmental statistics, or are ...
متن کاملVisual Noise from Natural Scene Statistics Reveals Human Scene Category Representations
Our visual perceptions are guided both by the bottom-‐up information entering our eyes as well as our top-‐down expectations of what we will see. Although bottom-‐up visual processing has been extensively studied, comparatively little is known about top-‐down signals. Here, we describe REVEAL (Representations Envisioned Via Evolutionary ALgorithm), a method for visualizing an observer's int...
متن کاملNatural Scene Statistics Account for the Representation of Scene Categories in Human Visual Cortex
During natural vision, humans categorize the scenes they encounter: an office, the beach, and so on. These categories are informed by knowledge of the way that objects co-occur in natural scenes. How does the human brain aggregate information about objects to represent scene categories? To explore this issue, we used statistical learning methods to learn categories that objectively capture the ...
متن کاملCortical Surround Interactions and Perceptual Salience via Natural Scene Statistics
Spatial context in images induces perceptual phenomena associated with salience and modulates the responses of neurons in primary visual cortex (V1). However, the computational and ecological principles underlying contextual effects are incompletely understood. We introduce a model of natural images that includes grouping and segmentation of neighboring features based on their joint statistics,...
