During the 1950s **John Brown**(([[http://step.psy.cmu.edu/articles/Brown58.doc|Brown, J. Some Tests of the Decay Theory of Immediate Memory. Quarterly Journal of Experimental Psychology 10, 12-21. 1958.]])) and **Lloyd and Margaret Peterson**(([[http://www.ncbi.nlm.nih.gov/pubmed/14432252|Peterson, L. R., & Peterson, M. J. Short-term retention of individual verbal items. Journal of Experimental Psychology, 58, 193-198. 1959.]])) conducted research on information forgetting, offering other explanations of forgetting. Their hypothesis was that forgetting occurs due to the rapid **decay of the memory trace** (//the neural substrate of retention//) when it is first established. Both reasons will later be accepted as correct. | During the 1950s **John Brown**(([[http://step.psy.cmu.edu/articles/Brown58.doc|Brown, J. Some Tests of the Decay Theory of Immediate Memory.

Another issue discussed during 1960s was weather human memory system has one or two components. Some authors like **[[http://books.nap.edu/html/biomems/amelton.pdf|Arthur Melton]]**(([[http://www.dtic.mil/cgi-bin/GetTRDoc?AD=AD0422425&Location=U2&doc=GetTRDoc.pdf|Melton, Arthur W. Implication of short-term memory for a general theory of memory, October 1963.]])) argued that both short term memory (STM) and long term memory (LTM) are just two subcomponents dependent on the same system. He justified his views by proofs of activation of the LTM in STM experiments. His work was very influential, yet during the years more and more evidence of at least two separate memory systems have accumulated. | Another issue discussed during 1960s was weather human memory system has one or two components.

- | Another term should be clarified here: the [[memory_models:human_working_memory|working memory]], which is often mistaken for the short-term memory. The main difference between these two is that working memory usually includes the structure and processes operated by a system in control of the short-term memory. | + | Another term should be clarified here: the [[memory_models:human_working_memory|working memory]], which is often mistaken for the short-term memory.
