Assessing the effects of "native speaker" status on classic findings in speech research.

It is common practice in speech research to only sample participants who self-report being "native English speakers." Although there is research on differences in language processing between native and nonnative listeners (see Lecumberri et al., 2010, for a review), the majority of speech research that aims to establish general findings (e.

Recall of Speech is Impaired by Subsequent Masking Noise: A Replication of Experiment 2.

Introduction: The presence of masking noise can impair speech intelligibility and increase the attentional and cognitive resources necessary to understand speech. The first study to demonstrate the negative cognitive effects of noisy speech found that participants had poorer recall for aurally-presented digits early in a list when later digits were presented in noise relative to quiet (Rabbitt, 1968). However, despite being cited nearly 500 times and providing the foundation for a wealth of subsequent research on the topic, the original study has never been directly replicated.
