The ubiquity of multitasking has led researchers to investigate its potential costs for reading and learning (Clinton‐Lisell, 2021). While some studies have not shown detrimental effects of multitasking for reading comprehension (Bowman et al., 2010; Cho et al., 2015; Pashler et al., 2013), one particular study has found a benefit of multitasking (Tran et al., 2013). These results, nevertheless, do not converge with the findings of recent meta-analyses, which have suggested both a negative effect of multitasking for reading comprehension (Clinton‐Lisell, 2021), as well as the disruptive effects of listening to lyrical music while reading for comprehension (Vasilev et al., 2018). Previous research seems to converge with the theories of how working memory copes with the complexity of reading as a process, since several subprocesses must be orchestrated so that the ultimate goal of reading – the construction of a mental representation – is fully achieved (Tomitch, 2020). In addition to that, no previous study has investigated reading as a multilevel construct in which both literal and inferential comprehension (Alptekin & Erçetin, 2010; Kintsch, 1998) is assessed in a multitasking setting. With that in mind, we investigated whether working memory capacity, measured by the Self-Administrable Reading Span Test (Oliveira et al., 2021), predicts proficient bilinguals’ performance in literal and inferential comprehension, by means of comprehension questions (Pearson & Johnson, 1978) and reading times, under a multitasking setting in two conditions – listening to lyrical music (experimental) as opposed to listening to non-lyrical music (control). Multiple linear regression analyses revealed that working memory capacity significantly predicted inferential, but not literal comprehension nor reading times, and only when participants were listening to lyrical music. Results are discussed both in terms of the effects of multitasking on reading comprehension as well as the role of working memory in language comprehension.
