Disneyland Park, originally Disneyland, is the first of two theme parks built at the Disneyland Resort in Anaheim, California, opened on July 17, 1955. It is the only theme park designed and built under the direct supervision of Walt Disney. It was originally the only attraction on the property; its name was changed to Disneyland Park to distinguish it from the expanding complex in the 1990s.
Walt Disney came up with the concept of Disneyland after visiting various amusement parks with his daughters in the 1930s and 1940s. He initially envisioned building a tourist attraction adjacent to his studios in Burbank to entertain fans who wished to visit; however, he soon realized that the proposed site was too small. After hiring a consultant to help him determine an appropriate site for his project, Walt bought a 160-acre (65 ha) site near Anaheim in 1953. Construction began in 1954 and the park was unveiled during a special televised press event on the ABC Television Network on July 17, 1955.
Since its opening, Disneyland has undergone a number of expansions and renovations, including the addition of New Orleans Square in 1966, Bear Country (now Critter Country) in 1972, and Mickey's Toontown in 1993. Disney California Adventure Park was built on the site of Disneyland's original parking lot and opened in 2001.
Disneyland has a larger cumulative attendance than any other theme park in the world, with over 650 million guests since it opened. In 2013, the park hosted approximately 16.2 million guests, making it the third most visited park in the world that calendar year. According to a March 2005 report from the Disney Company, there are 65,700 jobs supported by the Disneyland Resort, which includes, at the Resort itself, 20,000 direct Disney employees and 3,800 third-party employees (that is, independent contractors or their employees).
The Salk Institute, where researchers analyzed the data from the first of several brain exams on Genie.
Genie (born 1957) is the pseudonym of a feral child who was the victim of extraordinarily severe abuse, neglect and social isolation. Her circumstances are recorded prominently in the annals of abnormal child psychology. Born in Arcadia, California, United States, Genie's father kept her locked alone in a room from the age of 20 months to 13 years, 7 months, almost always strapped to a child's toilet or bound in a crib with her arms and legs completely immobilized. During this time she was never exposed to any significant amount of speech, and as a result she did not acquire a first language during childhood. Her abuse came to the attention of Los Angeles child welfare authorities on November 4, 1970.
In the first several years after Genie's life and circumstances came to light, psychologists, linguists and other scientists focused a great deal of attention on Genie's case, seeing in her near-total isolation an opportunity to study many aspects of human development. Upon finding that she had not yet learned a language, linguists saw Genie as potentially being an important way to gain further insight into the processes controlling language acquisition skills and linguistic development. Extensive observation of their new-found human subject enabled them to publish multiple academic works testing theories and hypotheses identifying critical periods during which humans learn to understand and use language. In addition, tests on Genie's brain found discrepancies far larger than any prior observations of people with fully intact brains, giving rise to many new hypotheses on brain lateralization and its effect on both language and other mental processes.
