Previous studies suggest that tasks dependent on the mental number line may be difficult for Williams Syndrome (WS) and Down (DS) groups. However, few have directly assessed estimation in these The current study 28 WS, 25 DS typically developing (TD) participants non-verbal intelligence, familiarity, visuo-spatial skills estimation. Group comparisons indicated no differences WS group displayed difficulties with familiarity. Differential relationships between visuo-spatial/number familiarity were observed across Data is discussed context of assessment neurodevelopmental disorders.
