The rey-osterrieth complex figure test (ROCF)

ROCF Is a neuropsychological assessment where subject are asked to reproduce a complicated line drawing. Participants need to copy the image then copy it by memory. Engage in this task elicits many cognitive abilities when performed correctly, therefor it can be used to evaluate different functions, such as visuao-spatial abilities, memory, attention, planning and the working memory/ executive functions. One aspect of this test was to differentiate between primary effects which is the direct results of the head injury and secondary effect which is developed out the subjective reactions determined by the loss of awareness from physical impairments.  In neuropsychology, the ROCF may be used to localize and assess the magnitude of brain damage. In education, the ROCF may be used to evaluate input processing of a child suspected of having a learning disability. Strength of this test is that it can be applied to a broad range of people such as children and adults that are normal, have learning difficulties and brain damage patients. The critique about this test is that the test has been widely used but there is a limited amount of published research articles suggesting the need for survey across a broad spectrum of test user such as neuropsychologist, clinical psychologist and school psychologist. The score criteria in relation to normative data and test results showed significant deviation not only from the standardized procedures set forth by Osterreith, but from one researcher to another. This deviation is appropriate with regards to normative data, but it is an area of concern with regards to other aspects of the test. For example, evaluation of test results must include consideration of the copy score derived from the elements of the ROCF design within the context of the organizational approach. Consideration must also be given to the subject's age as the research indicated a correlation between age and score and also implied that it may not be appropriate to administer the ROCF to children under 9 years old
