Measuring individual differences in working memory processes is challenging, particularly if one is interested in the question which specific aspect of working memory capacity is most relevant for individual differences in cognitive abilities. Mathematical models can address this issue, as they are capable of mapping processes of interest with parameters that are mathematically derived from hypotheses about the nature of these latent processes.
The Memory Measurement Model framework (M3; Oberauer & Lewandowsky, 2018) consists of a collection of such cognitive measurement models that isolate parameters associated with distinct working memory processes, such as the formation of bindings or the filtering of irrelevant distractors, in widely used paradigms like simple or complex span tasks. Based on simulations, we developed a series of experiments for different stimulus modalities, tailored to estimate the parameters of the M3 complex span models and to be concurrently used for electrophysiological research.
We demonstrate that the estimated parameters are related to specific neurocognitive processes such as the P300 and the CNV and are capable of mapping individual differences in these processes. We will discuss how this neurocognitive psychometric approach enables more precise measurement of latent working memory processes and whether model parameters can be mapped to neurocognitive correlates.
