Approach Ecological Perception Visual

introduction by Stephen PalmerIrvin Rock was a global perceptual theorist in the grand tradition of von Helmoltz, Wertheimer, and Gibson. This posthumous volume, the culmination of a long and distinguished career, brings together an original essay by the author together with a careful selection of previously published articles (most by Rock) on the theory that perception is an indirect process in which visual experience is derived by inference, rather than being directly and independently determined by retinal stimulation.Rock's reasons for holding that perception is indirect were mainly empirical. Unlike many theorists, he paid close attention to a broad range of experimental evidence in evaluating theoretical claims. His approach, in which theory and experiment go hand in hand, is well represented in this book.In the first chapter, which is new, Rock lays out the theoretical issues underlying indirect perception. The remaining twenty-two chapters present detailed evidence in support of the indirect view. They are divided into sections covering indirect perception, organization, shape, motion, illusions, lightness, and final considerations. Each section is introduced by the author. Stephen Palmer's introduction to the book places Rock's work within the context of the history of perceptual theory -- approaches formulated by Helmholtz (inferential), by the Gestaltist psychologists (organizational), and by Gibson (ecological).

Visual Approach Slope Indicator - The Visual Approach Slope Indicator (VASI) is a system of lights on the side of a runway that provide visual descent guidance information during the approach to a runway. These lights are visible from 3-5 miles during the day and up to 20 miles or more at night.

Visual perception - Visual perception is one of the senses, consisting of the ability to detect light and interpret (see) it as the perception known as sight or naked eye vision. Vision has a specific sensory system, the visual system.

Motion perception - Motion perception is the process of inferring the "true" velocity and direction of motion in a visual scene given some visual input. While humans appear to perform this task effortlessly in most cases, it has proven to be a hard problem from an information processing perspective.

Precision Approach Path Indicator - The Precision Approach Path Indicator (PAPI) is a light system positioned beside the runway that consists of two or four boxes of lights that provide a visual indication of an airplane's position on the glidepath for the associated runway. The FAA standard for the PAPI is the same as the ICAO's standard Visual Glide Slope Indicator.
