The present paper explores the generality of the Hebb repetition effect to the learning of olfactory sequences in order to assess commonality of memory functioning across sensory modalities. Participants completed a serial-order reconstruction task comprising sequences of four olfactory stimuli. Following presentation of each sequence, participants were re-presented with the odours and were required to reconstruct their order of presentation. Surreptitious re-presentation of the repeated sequence occurred on every third trial. This order reconstruction task produced a serial-position function comprising recency only for both the non-repeated and the repeated sequences. Importantly, serial-order reconstruction for the repeated odour sequence produced improved performance for that sequence compared to the non-repeated sequences. This observation of a Hebb repetition effect for olfactory sequences further supports the proposition that sequential learning can operate amodally.
