Inter-Rater Reliability Consistency between different researchers working on the same study. Test Re-test Method Participants take the same test on different occasions. High correlation between test scores = high external reliability. Validity Extent to which a measure measures what it is supposed to measure. Internal Validity.

To optimize the validity and reliability of the neural states detected by GSBS, we improved the algorithm in several ways, as shown in the ‘Supplementary methods’ section in Appendix 1. Searchlights in which we were unable to identify reliable neural state boundaries were excluded from further analysis (see Appendix 1—figure 5 ).
