内容简介：
As the most frequent developmental problem, unidentified, misdiagnosed, and untreated learning disabilities have very serious clinical, educational, social, and economic consequences which are beginning to receive the attention they really deserve.
The Mangina Diagnostic Tool of Visual Perception (Mangina-Test) precisely and accurately identifies different degrees of "analytical-specific visual perception" as it relates to real and specific perceptual learning abilities and disabilities.
As an aid to specialists in constructing specific, accurate diagnoses, the Mangina-Test makes it possible to distinguish difficulties in mathematics and/or reading comprehension that are caused by real learning disabilities from those that are motivational and/or emotional.
In addition, the non-verbal structure of the instrument enables specialists to better control the variables involved. Also relevant in this respect is its culture-free structure which assures that culture variables will not interfere with the diagnosis of the problem. This aspect allows for international use of the diagnostic test, irrespective of linguistic and/or cultural context.
This third edition--revised and expanded-- is based on empirical research and clinical applications. It offers unique clinical, theoretical, and methodological support for an integrated understanding of the development of neurocognitive abilities and disabilities.
"The Mangina-Test must be used with professional care for diagnostic, clinical, or research purposes. The sale of this instrument is, therefore, restricted to accredited universities, hospitals, governmental agencies, school boards, and to the qualified specialists affiliated with similar institutions."
