The environmental context dependency effect refers to the phenomena that memory performance is better when the environmental context at encoding is reinstated at the test than when it is not reinstated. Conventional wisdom states that the reinstatement of the environmental context does not affect memory performance when better cues, such as item cues, are available (e.g., Godden & Baddeley, 1980). I investigated whether the effect of the environmental context on the performing a graphemic cued recall task with item cues depends on the retention interval. Forty, graphemic to-beremembered items were presented to participants incidentally and the participants engaged in a cued recall task. The retention interval was one week in Experiment 1 and 10 minutes in Experiment 2. The environmental context cue was an odor. Reinstatement of the environmental context cues facilitated performance only in Experiment 1. This result suggests that environmental context cues are effective in graphemic cued recall when the effects of item cues are reduced by a long retention interval.
