A limitation of research into cue-dependent forgetting is that alternative research suggests memory may be state-dependent rather than context-dependent.

This was demonstrated by Carter + Cassaday (1998)
who provided pps with chlorpheniramine (an antihistamine with sedative effects, causing a drowsy internal state) and tested their recall of word lists.
They found that pps who learned and recalled in differing states (e.g. learning drowsy, recalling normal) performed significantly worse than pps who were in the same state throughout.
This is because when in the same internal state for both conditions, relevant cues were present, aiding retrieval, thus improving recall.
This suggests that internal cues may also aid the retrieval process.

Therefore further research into cue-dependent memory should considercues in both the internal and external environment and howtheyinteract.
