Abstract

The irrelevant sound effect (ISE) is the finding that irrelevant sound impairs recognition memory performance. Traditionally explored in serial recall, the current study attempts to elicit the effect in a surprise recognition task. Of the many ISE models, only the Object-Oriented Episodic Record (O-OER) model approaches the effect from an order-centric position. As such, given reduced need for order information in this design, O-OER predicts a null effect. A successful manipulation check in Experiment 1 confirmed that the stimuli were sufficient to produce the effect under a standard serial recall design and confirmed statistical equivalency between in-person and online participants. Experiment 2, expanding on Stokes and Arnell (2012), implemented a surprise two alternative forced choice (2AFC) recognition task under quiet, steady-state, and changing-state sound. Performance in the two statistically equivalent sound conditions was impaired, a result consist with all predictions. Experiments 3 and 4 followed this same design but employed alternative cover tasks. Neither experiment reported statistical differences between sound conditions. These results are best described by the O-OER model, however implications for other models such as the Feature model are also discussed.
