The common factor model assumes that the linear coefficients (intercepts and factor loadings) linking the observed variables to the latent factors are fixed coefficients (i.e., common for all participants). When the observed variables are participants' observed responses to stimuli, such as their responses to the items of a questionnaire, the assumption of common linear coefficients may be too ...

The exact mechanisms by which humans control the manual interception of moving targets are currently unknown. Here, the authors explored the behaviors associated with the spatial control for manual interception. The examined task required controlling a cursor to intercept moving targets on a touch screen. They explored the effects of target motion direction, curvature and occlusion on manual in...

One way to combine data from single-subject experimental design studies is by performing a multilevel meta-analysis, with unstandardized or standardized regression coefficients as the effect size metrics. This study evaluates the performance of this approach. The results indicate that a multilevel meta-analysis of unstandardized effect sizes results in good estimates of the effect. The multilev...
