Self-reference (or self-referential?processing) refers to the cognitive processes underlying self-related information processing.?It is?widely studied in cognitive neuroscience to understand the neural basis of self-cognition?of human beings.?However, does the term?“self-reference” mean the same psychological processes across studies? This fundamental question is largely neglected. To fill the gap, we?built?an?ontological dataset based on neuroimaging studies of?self-reference.?We searched the?literature and screened the articles following a standard protocol. Then,?two independent coders?extracted data and standardized operationalizaions of self-reference on?both?behavioral and neural levels, resulting in?a cognitive ontological dataset?for?neuroimaging studies of?self-reference. This dataset consists of operationalizations of self-reference (in CSV file format) from 66 neuroimaging articles, coordinates data?of brain areas activated by self-reference (in BrainMap format), and corresponding codebooks.?The inter-rater reliability analysis?suggests?that?the?quality of the coding process is excellent. Compared to automatic meta-analytical platforms, i.e., Neurosynth, the current dataset provides a fine-grained granularity in article selection, which allows the comparison of?brain regions activated by different operationalizations?of self-reference. This dataset lays a foundation for the understanding of neural mechanisms underlying?self-cognition. It may?also facilitate the study of cognitive ontology by providing an example for creating similar metascience datasets.
