The purpose of this study was to compare the equating errors item and ability parameters obtained by performing scale transformation methods two multidimensional test forms under various conditions. Sample size (1000-2000), common ratio (20% 40%), correlation between dimensions (0.1-0.5-0.9) parameter estimation model (2PLM-3PLM) were taken as research Equating error (RMSE) used examine accurac...

It is commonly believed that objects viewed in certain contexts may be more or less salient. Measurements of salience have usually relied on asking observers "How much does this object stand out against the background?". In this study, we measured the salience of objects by assessing the distraction they produce for subjects searching for a different, pre-specified target. Distraction was measu...
