Carving Executive Control at Its Joints: Working Memory Capacity Predicts Stimulus-Stimulus, but Not Stimulus-Response, Conflict
Peer reviewed Peer reviewed

Meier, Matt E.; Kane, Michael J. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2015
Three experiments examined the relation between working memory capacity (WMC) and 2 different forms of cognitive conflict: stimulus-stimulus (S-S) and stimulus-response (S-R) interference. Our goal was to test whether WMC's relation to conflict-task performance is mediated by stimulus-identification processes (captured by S-S conflict),…

Type I Error Inflation in the Traditional By-Participant Analysis to Metamemory Accuracy: A Generalized Mixed-Effects Model Perspective
Peer reviewed Peer reviewed
Direct linkDirect link
Murayama, Kou; Sakaki, Michiko; Yan, Veronica X.; Smith, Garry M. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2014
In order to examine metacognitive accuracy (i.e., the relationship between metacognitive judgment and memory performance), researchers often rely on by-participant analysis, where metacognitive accuracy (e.g., resolution, as measured by the gamma coefficient or signal detection measures) is computed for each participant and the computed values are…

Generalization Effects vs Random Effects: Is "Sigma Squared, Treatment-Language" a Source of Type 1 or Type 2 Error?
Coleman, Edmund B. – Journal of Verbal Learning and Verbal Behavior, 1979
Presents two experiments which demonstrate that language-generalization tests should tend to decrease Type 2 errors. (AM)
