There is strong evidence that age is positively related to declarative knowledge (McArdle et al., 2002), potentially because living through a certain event or situation could be essential for building knowledge on the respective topic (Beier & Ackerman, 2001). We therefore assume that an individual’s biography influences their performance on a declarative knowledge test. If this assumption holds, item sampling would influence the results of knowledge tests more strongly than traditional measurement models reflect (Schroeders et al., 2021). Based on a preliminary study (N = 104), we chose the following design for the present study: First subjects will work on declarative knowledge questions covering 22 domains. Knowledge domains were selected based on prior investigations on the dimensionality of crystallized intelligence (Steger, Schroeders, & Wilhelm, 2019). Additionally, subjects will answer biographical questions that are designed to match the content of the knowledge items. (contributors in alphabetical order) |
