Sheet 1 (Absolute conditioning): Absolute PER conditioning protocol using 6 conditioning trials. Conditioned stimulus (predictor variable) included 8 volatiles (linalool, dipentene, myrcene, geranium, linalool and petrol pollution, dipentene and petrol pollution, myrcene and petrol pollution, geranium and petrol pollution). Response variable = proboscis extension (binary response following exposure to conditioned stimuli: 0 no proboscis extension, 1 proboscis extension). Sheet 2 (Recall tests): Proboscis extension following exposure to 1 of 8 conditioned stimuli (linalool, dipentene, myrcene, geranium, linalool and petrol pollution, dipentene and petrol pollution, myrcene and petrol pollution, geranium and petrol pollution), 1 hr, 24 hrs and 48 hrs post conditioning. Response to conditioned stimuli and conditioned stimuli with or without the addition of petrol exhaust pollution was recorded.
