subjects were able to successfully model the construction of a simple symmetrical block structure when shown a video of a peer building the same configuration (Meyer, 1998). Additional research has shown that children with prenatal alcohol exposure differentially process specific features of visual stimuli. On a hierarchical processing task consisting of large symbols (the global feature) made up of smaller symbols (the local feature), alcohol-exposed children had significantly greater difficulty processing local features compared to global features (Mattson, Gramling, Delis, Jones, & Riley, 1996).
