Odor in the global environmental context: The effect of odor context reinstatement on memory

Previous research has demonstrated that memory is dependent on the environmental context; memory is better when the same environmental context cues present at study are reinstated at test as compared to when they are not. This finding is called context reinstatement effects (Godden & Baddeley, 1975; Smith, Glenberg, and Bjork, 1978; Smith & Vela, 2001). What is unclear is whether study items are associated with the global context or with unique features within the study environment. We tested whether reinstating a singular feature of a global environment, the odor present during study, was sufficient to produce context reinstatement effects. These results indicated that, in a global environmental context, the global context is not being used as a cue for all the studied items rather than unique aspects of the environment serving as unique cues
