Developmental Scoring System for the Rey-Osterrieth Complex [1]
The ROCF assesses perceptual organization and visual memory. The Developmental Scoring System "allows the examiner to objectively evaluate ROCF performance within a developmental context and to determine the age-appropriateness of the child's Copy and Recall productions.
The DSS-ROCF measures not only the child's ability to accurately reproduce the figure, but also the child's qualitative, organizational, and stylistic approaches to the figure."
On the Psychological Assessment Resources (PAR) website (www.parinc.com [2]), it states: "DSS-ROCF measures four parameters of ROCF performance:
Organization, Style, Accuracy, and Errors. Age-referenced norms for these four parameters provide guidelines for determining the developmental appropriateness of a child's production. The Organization score quantifies the child's appreciation for the organizational goodness of complex, visually represented materials. The Style rating objectively categorizes the child's approach to information processing as Part-oriented, Intermediate, or Configurational.
The Accuracy score quantifies the actual ROCF elements that are accurately reproduced (independent of Organization and
Style).
The Error score quantifies the extent to which elements are distorted (rotation, perseveration, misplacement, and conflation).”
