Reading is an active process of understanding and gaining knowledge from written text. A text may comprise written language in the form of an alphabet or other writing system, such as Braille. Other types of reading may not be text-based, such as music notation or pictograms. By analogy, in computer science, reading is the acquisition of data from some sort of computer storage.
Reading is a means of acquiring language, of communication, and of sharing information and ideas. Effective reading involves the use of prior knowledge (schemata theory) and decoding skills (using morphemic, semantic, and syntactic cues).
Although reading is now an important primary way for many people to receive information - such as on the Internet - this has been the case only for the last 150 years or so. With some exceptions, such as colonial America, only a small percentage of the population in any country was literate before the Industrial Revolution.
Rates of reading include reading for memorization (under 100 words per minute or wpm), reading for learning (100-200 wpm), reading for comprehension (200-400 wpm), and skim reading (400-700 wpm). Reading for comprehension is the essence of most people's daily reading. Skimming is sometimes useful for processing larger quantities of text superficially at a much lower level of comprehension (below 50%).
Advice for the appropriate choice of reading rate includes reading flexibly, slowing down when the concepts are closely related or when the material is unfamiliar, and speeding up when the material is familiar and the material is not complicated. Speed reading courses and books often encourage the reader to continually speed up; comprehension tests lead the reader to believe that their comprehension is constantly improving. However, competence in reading involves multiple approaches to the text, from skim reading to close reading, in order to gain understanding.
We can identify several types and methods of reading, with differing rates of understanding that can be attained for each, for different kinds of material and purposes:
Several methods of teaching and learning to read have developed, and become somewhat controversial:
For most children in the United States of America, formal training to read begins in kindergarten (approximately age 5), and most children have learned to read by the age of 6 or 7.
The issue of when a child is "ready" to be taught to read goes under the name reading readiness, and there is some debate among educational psychologists about when this is. Generally, when children have displayed certain signs, such as taking an interest in words, knowing his or her name, and knowing the alphabet, they might be considered ready to learn to read. Many reading experts believe that aggressive attempts to teach children to read before they are ready will in too many cases lead to frustration and, as a result, bad associations with reading. They also dismiss very early reading programs as only teaching children to "bark at print"--that is, merely memorize the association of the shape of the word with the sound of the word, without getting meaning. Nevertheless, there are cases of infants under one year of age can memorize the connection between the shape of words and objects,[2] but it is not until some time after that they are capable of decoding words or "making sense" of entire sentences. There have been two- and three-year-olds who are capable of reading "first reader" type books on their own and with some comprehension; see accelerated early childhood education.
It is much more widely agreed that, to get small children ready to read, it is important that they be read to, even from infancy. This teaches familiarity with words and their sounds (or phonemes) and with books and how to hold them, as well as teaching some vocabulary and comprehension that are necessary to getting meaning later.
Learning to read in a second language, especially in adulthood, may be a different process than learning to read a first language in childhood. There are cases of very young children learning to read without having been taught, such as described in the book Learning From Children Who Read at an Early Age by Rhona Stainthorp and Diana Hughes.[3] Such was the case with Truman Capote, as noted in his New York Times obituary:
After his mother's divorce from Mr. Persons and her marriage to Joe Capote, she brought her son to live with them in New York. He was sent to several private schools, including Trinity School and St. John's Academy in New York, but he disliked schools and did poorly in his courses, including English, although he had taught himself to read and write when he was 5 years old. Having been told by many teachers that the precocious child was probably mentally backward, the Capotes sent him to a psychiatrist who, Truman Capote said triumphantly some years later, "naturally classified me as a genius."
In Gerald Clarke's Capote: A Biography (1988), one paragraph describes how Capote was usually seen at age five carrying his dictionary and notepad. Conversations with Truman Capote has a passage telling how Capote taught himself to read (in a town with no library) by collecting old farm magazines and each day at 6 p.m. meeting the bus which dropped off the two newspapers from Mobile and Montgomery. Another example is Hadley Bond, a gifted child in Australia who taught himself to read by the age of one-and-a-half, had a library at age two and taught himself maths at the age of three. There are numerous accounts of people who taught themselves to read by comparing street signs or Biblical passages to speech, plus many mentions of Abraham Lincoln teaching himself. The novelist Nicholas Delbanco taught himself to read at six by studying a book about boats during a transatlantic crossing.
Because reading draws on multiple types of knowledge, it can be tested in several different ways. Tests also vary depending on whether they are used to test children or adults. Standardized tests are normed to a large population of readers, allowing the tester to determine what is typical for an individual of a given age. For example, the average reading ability of children aged 10 years, 0 months will be 10;0. However, a more advanced eight year old might also be able to read at the 10;0 level.
Reading achievement is influenced by multiple factors, and is not limited to a child's Intelligence quotient.
Some tests incorporate several of the above components at once. For instance, the Nelson-Denny reading test scores readers both on the speed at which they can read a passage, and also their ability to accurately answer questions about it.
Studies have shown that American children who learn to read by the third grade (8-9 years) are less likely to end up in prison, drop out of school, or take drugs. Adults who read literature on a regular basis are nearly three times as likely to attend a performing arts event, almost four times as likely to visit an art museum, more than two-and-a-half times as likely to do volunteer or charity work, and over one-and-a-half times as likely to participate in sporting activities.[4] Literacy rates in the USA are also more highly correlated to weekly earnings than IQ.[5] Reading books is generally regarded as being a relaxing pastime, while at the same time stimulating the brain to process text.
Reading requires more lighting than many other activities, so the possibility of comfortable reading in cafés, restaurants, buses, in parks and so on greatly varies depending on available lighting and time of day. In the 1950s, many offices and classrooms were over-illuminated, but since about 1990, there has been a movement to create reading environments with appropriate lighting levels (approximately 600 to 800 lux).
