However, language control in production can involve switch costs. That is, switching to another language takes longer than staying in the same language. Moreover, bilinguals sometimes produce language intrusion errors, mistakenly producing words in an unintended language (e.g., Spanish-English bilinguals saying "pero" instead of "but"). Switch costs are also found in comprehension. For example, reading times are longer when bilinguals read sentences with language switches compared to sentences with no language switches. Given that both production and comprehension involve switch costs, some language-control mechanisms might be shared across modalities. To test this, we compared language switch costs found in eye-movement measures during silent sentence reading (comprehension) and intrusion errors produced when reading aloud switched words in mixed-language paragraphs (production). Bilinguals who made more intrusion errors during the read-aloud task did not show different switch cost patterns in most measures in the silent-reading task, except on skipping rates. We suggest that language switching is mostly controlled by separate, modality-specific processes in production and comprehension, although some points of overlap might indicate the role of domain general control and how it can influence individual differences in bilingual language control.Data outliers can carry very valuable information and might be most informative for the interpretation. Nevertheless, they are often neglected. An algorithm called cellwise outlier diagnostics using robust pairwise log ratios (cell-rPLR) for the identification of outliers in single cell of a data matrix is proposed. The algorithm is designed for metabolomic data, where due to the size effect, the measured values are not directly comparable. Pairwise log ratios between the variable
