The second cognitive limitation Miller discusses is memory span. Memory span refers to the longest list of items (e.g., digits, letters, words) that a person can repeat back in the correct order on 50% of trials immediately after the presentation. Miller observed that the memory span of young adults is approximately seven items.
Miller was born on February 3, 1920, in Charleston, West Virginia, the son of George E. Miller, a steel company executive [1] and Florence (née Armitage) Miller. [3] Soon after his birth, his parents divorced, and he lived with his mother during the Great Depression, attending public school and graduating from Charleston High School in 1937.
In experiments with the macaque monkey, Earl Miller and his colleagues used the delayed matching to sample (DMS) task to assess working memory in monkeys. [33] The monkey was required to fixate on a computer screen while coloured images were displayed serially for 0.5 seconds, and separated by a one-second delay.

The famously known capacity of memory of 7 plus or minus 2 is a combination of both memories in working memory and long-term memory. [ citation needed ] One of the classic experiments is by Ebbinghaus , who found the serial position effect where information from the beginning and end of the list of random words were better recalled than those ...
In 2010, experiments that have tested for the significance of under-performance of memory for an older adult group as compared to a young adult group, hypothesized that the deficit in associate memory due to age can be linked with a physical deficit. This deficit can be explained by the inefficient processing in the medial-temporal regions.
BSR also notably lacks an established neural representation in memory that naturally facilitates the learning of reward expectancy. Both of these effects lead to diminished response rate for BSR in the early trials of a series; however, experiments have also shown that extinguished behavior can be quickly reinstated by a priming stimulation ...
Information processing theory is the approach to the study of cognitive development evolved out of the American experimental tradition in psychology. Developmental psychologists who adopt the information processing perspective account for mental development in terms of maturational changes in basic components of a child's mind.
