====Physical environment====
The ___location and environment in which you learn something readily affects how you can freely recall it.<ref name="underwater study">{{cite journal|last=Godden|first=D.R.|author2=A.D. Baddely|title=Context-Dependent Memory in Two Natural Environments: On Land and Underwater|journal=The British Journal of Psychology|year=1975|volume=66|issue=3|pages=325–331|doi=10.1111/j.2044-8295.1975.tb01468.x}}</ref> In a famous experiment by Godden and Baddeley in 1975 researchers took two groups of individuals and asked them to study and remember a list of given words.<ref name="underwater study" /> One group was given a list of words to study while underwater in scuba gear, the other was given the same list on dry land. When asked to recall the information the participants remembered the list of words better when tested in the environment where the list was studied. This experiment illustrates how recreating the physical environment of encoding can aid in the retrieval process.<ref>{{Cite book|url=https://www.worldcat.org/oclc/885178247|title=Cognitive psychology : connecting mind, research and everyday experience|last=Goldstein, E.

The type of environment itself did not matter, just that the environment was constant during encoding and recall, as the effect on recall of the environment of recall depends on the environment of original learning.<ref name="underwater 2">{{cite journal|last=Godden|first=Duncan|author2=Alan Baddely|title=When Does Context Influence Recognition Memory?|journal=The British Journal of Psychology|year=1980|volume=71|pages=99–104|doi=10.1111/j.2044-8295.1980.tb02735.x}}</ref> Memory tested through recognition, however, was not affected. This phenomenon is explained by what is termed the [[Context-dependent memory#The outshining hypothesis|outshining hypothesis]]: context can be a useful cue for memory but only when it is needed. One will only turn to context as a cue when better cues are unavailable. In recognition tests, cues other than the immediate encoding context and environment are superior, whereas in free-recall tests, the immediate environment serves as the only cue to trigger memory.<ref name="underwater 2" />
