Perception

Perception (from the Latin perceptio, percipio) is the organization, identification, and interpretation of sensory information in order to represent and understand the environment. All perception involves signals in the nervous system, which in turn result from physical or chemical stimulation of the sense organs. For example, vision involves light striking the retina of the eye, smell is mediated by odor molecules, and hearing involves pressure waves. Perception is not the passive receipt of these signals, but is shaped by learning, memory, expectation, and attention.

Perception can be split into two processes Firstly processing sensory input which transforms these low-level information to higher-level information (e.g., extracts shapes for object recognition). Secondly processing which is connected with person's concept and expectations (knowledge), and selective mechanisms (attention) that influence perception.

Perception depends on complex functions of the nervous system, but subjectively seems mostly effortless because this processing happens outside conscious awareness.

Early Edu-Ware products

Most of the programs in Edu-Ware Service's initial product line, released in 1979 under the slogan "Unique software for the unique mind", were not typical of the intellectually challenging computer games and structured, pedagogically sound educational software for which the company would later become known. Quickly designed and programmed in Applesoft BASIC primarily by co-founder Sherwin Steffin, most of these text-based programs were dropped from Edu-Ware's catalog when the company began developing products featuring high-resolution graphics in 1981.

E.S.P.

E.S.P. is a game giving players the opportunity to find out whether they possess extrasensory perception. While displaying a constantly changing graphic design on the screen, the program briefly flashes emotionally charged words, randomly chosen from a word list, on the screen. The program then asks a series of questions to determine if the player's attitudes have been influenced by the subliminal messages. A file-builder is included to allow players to insert new words in the data base.

Philosophy of perception

The philosophy of perception is concerned with the nature of perceptual experience and the status of perceptual data, in particular how they relate to beliefs about, or knowledge of, the world. Any explicit account of perception requires a commitment to one of a variety of ontological or metaphysical views. Philosophers distinguish internalist accounts, which assume that perceptions of objects, and knowledge or beliefs about them, are aspects of an individual's mind, and externalist accounts, which state that they constitute real aspects of the world external to the individual. The position of naïve realism—the 'everyday' impression of physical objects constituting what is perceived—is to some extent contradicted by the occurrence of perceptual illusions and hallucinations and the relativity of perceptual experience as well as certain insights in science.Realist conceptions include phenomenalism and direct and indirect realism. Anti-realist conceptions include idealism and skepticism.

Pupil

The pupil is a hole located in the center of the iris of the eye that allows light to strike the retina. It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil.

In humans the pupil is round, but other species, such as some cats, have vertical slit pupils, goats have horizontally oriented pupils, and some catfish have annular types. In optical terms, the anatomical pupil is the eye's aperture and the iris is the aperture stop. The image of the pupil as seen from outside the eye is the entrance pupil, which does not exactly correspond to the location and size of the physical pupil because it is magnified by the cornea. On the inner edge lies a prominent structure, the collarette, marking the junction of the embryonic pupillary membrane covering the embryonic pupil.

Pupil (band)

Pupil is a Filipino rock band composed of Ely Buendia on lead vocals and guitars, Dok Sergio on bass, Wendell Garcia on drums and Jerome Velasco on guitars.

History

Formation

Pupil was formed when Dok Sergio from the bands The Teeth and Daydream Cycle joined The Mongols' line-up during the fourth quarter of 2004, making it a five-man band. The Mongols' bassist Yan "Yanni" Yuzon moved to third guitar duties while Dok Sergio handled bass. The transitional five-man line-up was witnessed in The Mongols’ last single and music video entitled “Heroine”. In May 2005, guitarist Jerome Velasco, a.k.a. J. Astro, left to pursue a career in producing, recording and studio engineering. The group's last gig under the name "The Mongols" was on July 7, 2005.

Velasco’s departure shook things up for the group as they were trapped into the decision of whether to stay as a band or not. As they decided to continue and as they progressed, the band noticed that they were producing a different sound without Velasco on the lead guitar and decided to form a "new" band. “We got a better bass player and dumber guitarist,” jokes guitarist Yan Yuzon, who left bass playing duties to Dok Sergio to take Velasco’s place. Upon the determination of forming a “new” band, the group’s first move was to change their name.
