Aim: Carter & Cassaday (1998) examined state-dependent forgetting using anti-histamine drugs. These are typically administered as hay fever relief to sufferers but are also known for their sedating effect. This can make the individual feel drowsy, and therefore not as alert as they would normally be, providing a comparison to everyday non-drug-induced behaviour.
Conclusion: When the physiological/emotional cues that are present at the time of encoding are missing at the time of retrieval (recall), state-dependent forgetting is likely to occur.
