Past research has supported the idea that self-regulation uses a limited resource which is subject to depletion (Hagger, Wood, Stiff, & Chatzisarantis, 2010). Depletion has generally been measured by the reduced accuracy of task performance on one executive function task that follows another executive function task. The current study used two measures of time within a speech processing task to explore the effects of depletion on complex speech processing. Half of the participants completed the speech processing task before an inhibitory writing task (Group A), and the other half of the participants completed the inhibitory writing task before the speech processing task (Group B); Group B was therefore predicted to be depleted in their ability to complete the speech processing task relative to Group A. During the speech processing task, participants listened to sentences from two different speakers simultaneously, one a native speaker of English and the other a non-native speaker of English. Listeners were visually cued to listen to and repeat one speaker or the other in a random sequence. After repeating each sentence, participants were given a forced choice question requiring them to identify the sentence spoken by the target speaker. The forced choice answer set provided two answer choices, the sentence spoken by the native speaker of English and the sentence spoken by the non-native accented speaker of English. Answers to these forced choice questions were used to verify whether participants had attended to the correct target. The current study analyzed response times for the forced choice questions (FCR) as well as the self-paced advancement (SPA) times (the times the participants waited before progressing from item to item). Times were analyzed for each participant and as means across participants between the two experimental groups. Results indicated no significant group differences for either forced choice response (FCR) times or self paced advancement (SPA) times. Regression analyses revealed a trend of decreasing SPA time over the course of the experiment but no trends were observed for FCR time. These results indicate a lack of depletion effects on measures of FCR and SPA time and the possible effect of increasing automaticity on the SPA time measure.
