Mediation analysis investigating the roles of visual identification and visual integration in the relation between intelligence impairments and TBI.

Note. The mediation analysis describes the relations between: (1) group membership and full-scale IQ (FSIQ, Path C); (2) group membership and Visual Integration Test performance (identification accuracy, integration accuracy and integration drift rate, Path A); (3) Visual Integration Test performance and FSIQ (Path B); and (4) group membership and FSIQ, corrected for Visual Integration Test performance (Path C’).
