Until the eighteenth century, blind people could not be educated and were taught only a simple trade. In 1784, Valentin Hauy became one of the pioneers in the education of blind \people. When > people when\ he established the National Institute for the Young Blind in Paris. After enlarging and embossing letters of the \alphabet. Hany > alphabet, Hauy\ taught his students to read the letters with their fingers. Hany's system was later improved by Louis \Braille. Who > Braille, who\ had been blinded in an accident at the age of three. Braille was educated in his village school and attended the National Institute for the Young Blind. Later, he became an instructor at the institute and was able to improve the reading method of his teacher. In 1829, he presented his new \system. Which > system, which\ used combinations of dots to represent numbers and letters of the alphabet. His new system is named after \him. And > him and\ is used throughout the world today to educate the blind.
Humans use three systems to remember information. The first system is
the sensory \memory. Whose > memory, whose\ information usually
disappears in about one \second. Unless > second unless\ the information
has been transferred to another memory. The second type of memory is the
short-term memory. Unless some further processing occurs within the short-term
memory, the information there disappears in about 30 seconds. This memory
generally holds up to seven items easily: for example, the number of digits
in a telephone number. When your short-term memory is full, you can add
new items only when old information disappears. Information is held in the
short-term memory and kept \current. Through > current through\
rehearsal until it is associated with similar information already present
in the long-term memory. The information is then more or less \permanent.
Depending > permanent depending\ on the kind of organization and
the individual's ability to recall the information. No one knows how much
information can be stored in the long-term memory or how long information
can be stored there. Some psychologists believe that the human memory has
definite \limits. While > limits while\ others believe that the
memory capacity is limited.
