“…Such a spatial focus is also highlighted in the BAS-R (Elliott et al, 1983) and WPPSI-IV (Wechsler, 2012). Next, "abstract reasoning" is highlighted in the MSCA (McCarthy, 1972) and SBV (Roid, 2003), which we think contributes to the overall structural complexity of the construction as assessed in the Three Methods of Evaluating the Complexity of Block Structures (Gregory & Whiren, 2003), BCSS (Phelps & Hanline, 1999;Hanline et al, 2001Hanline et al, , 2010, BPC (Ramani, 2012), and Block Structure Complexity Scoring Instrument (Trawick-Smith et al, 2017). "Representational thinking" points to the cognitive processes conducive to the building of mental models to represent some specific aspects of reality.…”
