Editing Interference theory (section)

===Context===
Proactive interference build-up occurs with memories being learned in similar contexts. A common example is observing previous motor abilities from one skill interfering with a new set of motor abilities being learned in another skill from the initial.<ref name="Edwards"/> Proactive interference is also associated with poorer list discrimination, which occurs when participants are asked to judge whether an item has appeared on a previously learned list.<ref>{{cite journal|last=Postman|first=Leo|author2=Keppel, Geoffrey|title=Conditions of cumulative proactive inhibition.|journal=Journal of Experimental Psychology: General|date=1 January 1977|volume=106|issue=4|pages=376–403|doi=10.1037/0096-3445.106.4.376}}</ref> If the items or pairs to be learned are conceptually related to one another, then proactive interference has a greater effect.<ref>{{cite journal|last=Underwood|first=Benton J.|title=Attributes of memory|journal=Psychological Review|date=1 January 1969|volume=76|issue=6|pages=559–573|doi=10.1037/h0028143}}</ref> [[Delos Wickens]] discovered that proactive interference build-up is released when there is a change to the category of items being learned, leading to increased processing in STM.<ref name="Wickens main">{{cite journal|last=Wickens|first=D.|author2=Moody, M. |author3=Shearer, P. |title=Lack of Memory for Unattended Items in Dichotic Listening.|journal=Journal of Experimental Psychology|year=1976|volume=2|issue=6|pages=712–719|doi=10.1037/0278-7393.2.6.712|pmid=1010994}}</ref> Presenting new skills later in practice can considerably reduce proactive interference desirable for participants to have the best opportunity to encode fresh new memories into LTM.<ref name="Edwards"/>
