The finding that serial recall perfonnance for visually presented items is impaired by concurrently presented speech or sounds is referred to as the irrelevant sound effect (lSE). The foremost explanation for the effect is based on interference with rehearsal and seriation processes. The present series of experiments demonstrates tha t neither rehearsal nor seriation processes is necessary to observe the ISE. Evidence comes from three experiments that a) allow participants to report to-be-remembered items in any order, b) eliminate rehearsal by engaging participants in a cover task and surprising them with a memory test, and c) show that surprise non-serial recognition is immune to rehearsal-based experimental manipulations that modulate the ISE in more typical serial recall tasks. Together,the results show that models that rely on rehearsal or seriation processes to account for the ISE need to be reconsidered. Results are discussed in tenns of interference with encoding of to-be-remembered material.

Alexander McLeod was Deputy Sheriff of the Niagara District during the Rebellion of 1837-38 in Upper Canada. On December 24, 1837, he became aware of a scheme by the rebels to use the American steamboat Caroline to provide supplies to William Lyon Mackenzie and his followers on Navy Island in the Niagara River. McLeod notified the authorities in Upper Canada about the situation. A few days later, on December 29, Commodore Andrew Drew led a band of men, including McLeod, to the American side, where the Caroline was moored at Schlosser’s Wharf. A scuffle ensued, in which American Amos Durfee was killed. The Caroline was then released from its moorings, set on fire, and drifted downstream before sinking. Many Americans viewed the incident as a violation of their sovereignty. Tensions between the United States and England were already strained over a boundary dispute between Maine and New Brunswick, and the situation with the Caroline further escalated the tension. McLeod was subsequently arrested in November, 1840 in Lewiston, NY and indicted for arson and murder. The British foreign secretary, Lord Palmerston, insisted that McLeod be released and could not be held personally responsible for the incident, as he was acting on orders from authorities in Canada. Eventually, McLeod was acquitted.
