摘要: Although common in the educational and developmental areas, multilevel models are not often utilized analysis of data from experimental designs. This article illustrates how can be useful with two examples designs repeated measurements involving time. One example demonstrates to properly examine independent variables for stimuli or individuals that categorical, continuous, semicontinuous presence missing data. The second response times error rates modeled simultaneously within a multivariate model order speed—accuracy trade-offs at experimental-condition individual levels, as well differences magnitude effects across outcomes.
