Editing Interference theory (section)

====Long-term memory====
Smith found that if categories with corresponding items were successfully recalled, a systematic decline would occur when recalling the items in a category across the output sequence.<ref name = "Smith, A.D.(1971)">{{cite journal | last1 = Smith | first1 = A.D. | year = 1971 | title = Output interference and organized recall from long-term memory | journal = Journal of Verbal Learning and Verbal Behavior | volume = 10 | issue = 4| pages = 400–408 | doi=10.1016/s0022-5371(71)80039-7}}</ref> He conducted multiple experiments to determine the input conditioned necessary to produce Output Interference.<ref name="Smith, A.D.(1971)"/> In his first experiment word recall per category was greater at 60 sec than 30 sec when taking the last input category out to prevent [[recency effect]].<ref name="Smith, A.D.(1971)"/> In his second experiment he changed the instructions, words used, and nature of the retention test, and showed with the recognition procedure, there was Output Interference but the effect was limited to the first three output positions.<ref name="Smith, A.D.(1971)"/> Even if retrieving items is necessary for a recall, it is not crucial to performance in a recognition tack.<ref name="Smith, A.D.(1971)"/> Recall of the organized information from long-term memory hurt the following item recalled.<ref name="Smith, A.D.(1971)"/> In long-term memory, Smith suggests that Output Interference has effects on extra-core material, which is represented as contextual information, rather than the core material, which is highly available as a result of organization.<ref name="Smith, A.D.(1971)"/>
