In this study, 6‐month‐old infants' visual working memory for a static feature (color) and a dynamic feature (rotational motion) was compared. Comparing infants' use of different features can only be done properly if experimental manipulations to those features are equally salient (Kaldy & Blaser, 2009; Kaldy, Blaser, & Leslie, 2006). The interdimensional salience mapping method was used to find two objects that each were one Just Salient Difference from a common baseline object ( N  = 16). These calibrated stimuli were then used in a subsequent two‐alternative forced‐choice preferential looking memory test ( N  = 28). Results showed that infants noted the color change, but not the equally salient change in rotation speed.
