“…In order to improve the accuracy of predictive and postdictive judgments in preschool age, researchers examined the effect of performance feedback ( Destan, Spiess, de Bruin, van Loon, & Roebers, 2017 ; Lipowski, Merriman, & Dunlosky, 2013 ; Urban & Urban, 2018 , 2020 ; van Loon, Destan, Spiess, de Bruin, & Roebers, 2017 ). Receiving performance feedback can improve metacognitive accuracy in preschoolers’ postdictions ( Urban & Urban, 2018 , 2020 ) and predictions ( Lipowski et al, 2013 ) from the age of 4 ( Geurten & Meulemans, 2017 ). To answer the question of why feedback has an effect on preschool children, Geurten and Meulemans (2017) decided to test the anchoring effect of feedback on the predictive judgments of children aged 4, 6 and 8 years old in memory tasks.…”
