The PRI is made up of three (usually the first three) of the four following subtests:
Block Design measures the child’s ability to analyze and synthesize abstract visual stimuli. This test requires the child to view a constructed model or a picture in the stimulus book, and use red-and-white blocks to re-create the design within a specified time limit.
Picture Concepts measures abstract, categorical reasoning ability. The child is presented with two or three rows of pictures and chooses one picture from each row to form a group with a common characteristic.
Matrix Reasoning measures fluid intelligence and provides a reliable estimate of general nonverbal intelligence. This test requires the child to view an incomplete matrix and select the missing portion from 5 response options.
Picture Completion measures visual perception and organization, concentration, and visual recognition of essential details of objects. This test requires the child to view a picture and then point to or name the important part missing within a specified time limit.
Problems with tracking and/or convergence, visual processing, visual attention or visual neglect, or visual-motor coordination can impact scores here. Knowing what the subtest scores were like can often be helpful in deciding whether to first rule out a larger problem in visual or spatial processing or to attribute the discrepancy to previously-diagnosed ADD. It is worth noting that it doesn't really appear that ADD adversely impacted any other areas, even the ones, such as PSI and WMI, that are more commonly affected by this, so I think it is worth checking out further, if the full report doesn't address it.
It doesn't appear to me that ADD is an issue--but I believe there is a strong genetic tendency in the family...I can see her thinking the other parts of the test were much more interesting and tuning out on this one though. Huh.
