Development of Iconic Memory
The development of iconic memory begins at birth and continues as development of the primary and secondary visual system occurs. By 6 months of age, infants' iconic memory capacity approaches adults' By 5 years of age, children have developed the same unlimited capacity of iconic memory that adults possess (ref needed). The duration of informational persistence however increases from approximately 200 ms at age 5, to an asymptotic level of 1000 ms as an adult (>11 years). A small decrease in visual persistence occurs with age. A decrease of approximately 20 ms has been observed when comparing individuals in their early 20's to those in their late 60's. Throughout one’s lifetime, mild cognitive impairments (MCIs) may develop such as errors in episodic memory (autobiographical memory about people, places, and their contex), and working memory (the active processing component of STM) due to damage in hippocampal and association cortical areas. Episodic memories are autobiographical events that a person can discuss. Individuals with MCIs have be found to show decreased iconic memory capacity and duration. Iconic memory impairment in those with MCIs may be used as a predictor for the development of more severe deficits such as Alzheimer’s disease and dementia later in life.

Famous quotes containing the words development of, development and/or memory:
“There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.”
—John Emerich Edward Dalberg, 1st Baron Acton (1834–1902)
“Understanding child development takes the emphasis away from the child’s character—looking at the child as good or bad. The emphasis is put on behavior as communication. Discipline is thus seen as problem-solving. The child is helped to learn a more acceptable manner of communication.”
—Ellen Galinsky (20th century)
“I regard a love for poetry as one of the most needful and helpful elements in the life- outfit of a human being. It was the greatest of blessings to me, in the long days of toil to which I was shut in much earlier than most young girls are, that the poetry I held in my memory breathed its enchanted atmosphere through me and around me, and touched even dull drudgery with its sunshine.”
—Lucy Larcom (1824–1893)
