Replication Data for: Stereotype Threat and Group Differences in Test Performance: A Question of Measurement Invariance
TL;DR: ST theory is related to the psychometric concept of measurement invariance and it is shown that ST effects may be viewed as a source of measurement bias and are detectable by means of multi-group confirmatory factor analysis.
Journal ArticleDOI
Peer Review Quality and Transparency of the Peer-Review Process in Open Access and Subscription Journals.
TL;DR: The tool to assess transparency of the peer-review process at academic journals shows promising reliability and validity, and can be seen as an indicator of peer- review quality allowing the tool to be used to predict academic quality in new journals.

Stereotype Threat and Group Differences in Test Performance: A Question of Measurement Invariance
TL;DR: In this article, the effects of stereotype threat (ST) on test performance have shed new light on race and sex differences in achievement and intelligence test scores, and the authors relate ST theory to the psychometric concept of measurement invariance.
