Dear Colleagues, We – Diana Klose, Ulrich Schroeders, and Timo Gnambs – are currently conducting a meta-analysis on ability assessments in proctored and unproctored settings. We would like to invite you to contribute by providing unpublished articles and manuscripts. With this meta-analysis, we want to provide an overview of studies conducted on the comparability of proctored and unproctored ability assessments. To be included in our analysis, studies need to include a measure of cognitive abilities conducted both in a proctored (e.g. lab) and in an unproctored setting (e.g., web-based). If you have unpublished work (including unpublished data or manuscripts) that fit the description, we would be very grateful if you could send a copy of the respective work to diana.klose@uni-bamberg.de by April, 21 2017. We are looking forward to hearing from you.
