Ravens intelligence test

  1. 1. Psychological Testing: Ravens ProgressiveMatricesWikipedia Updated: Nov 10th 2010Ravens Progressive Matrices (often referred to simply as Ravens Matrices) are multiplechoice intelligence tests of abstract reasoning, originally developed by Dr. John C. Raven in1936.[1] In each test item, the subject is asked to identify the missing item that completes apattern. Many patterns are presented in the form of a 4x4, 3x3, or 2x2 matrix, giving the testits name.VersionsThe matrices are posed in three different forms for participants of different ability: • Standard Progressive Matrices: These were the original form of the matrices, first published in 1938. The booklet comprises five sets (A to E) of 12 items each (e.g., A1 through A12), with items within a set becoming increasingly difficult, requiring ever greater cognitive capacity to encode and analyze information. All items are presented in black ink on a white background. • Coloured Progressive Matrices: Designed for younger children, the elderly, and people with moderate or severe learning difficulties, this test contains sets A and B from the standard matrices, with a further set of 12 items inserted between the two, as set Ab. Most items are presented on a coloured background to make the test visually stimulating for participants. However the very last few items in set B are presented as black-on-white; in this way, if a subject exceeds the testers expectations, transition to sets C, D, and E of the standard matrices is eased. • Advanced Progressive Matrices: The advanced form of the matrices contains 48 items, presented as one set of 12 (set I), and another of 36 (set II). Items are again presented in black ink on a white background, and become increasingly difficult as progress is made through each set. These items are appropriate for adults and adolescents of above-average intelligence.In addition, so-called "parallel" forms of the standard and coloured progressive matrices werepublished in 1998. This was to address the problem of the Ravens Matrices being too well-known in the general population. The fact that testees have grown increasingly experiencedwith the Ravens over the last 60 years could explain the increases in scores of around 10 IQpoints per generation (see Flynn effect). Items in the parallel tests have been constructed so thataverage solution rates to each question are identical for the classic and parallel versions. Anextended form of the standard progressive matrices, Standard Progressive Matrices Plus, waspublished at the same time, offering greater discrimination among more able young adults.
  2. 2. The Triple Nine Society, a high IQ society, accepts the Advanced Progressive Matrices form forone of their admission tests. They require a score of at least 32 out of 36 on or before December31, 1999 on the RAPM. The International Society for Philosophical Enquiry (ISPE) similarlyaccepts the RAPM as a qualification for admission.Underlying factorsAccording to their author, Ravens Progressive Matrices and Vocabulary tests measure the twomain components of general intelligence (originally identified by Charles Spearman): the abilityto think clearly and make sense of complexity, which is known as eductive ability (from theLatin root "educere", meaning "to draw out") and the ability to store and reproduce information,known as reproductive ability.A matrix example.A 2007 study provided evidence that individuals with Asperger syndrome, a high-functioningautism spectrum disorder, score higher than other individuals on Ravens tests.[2] Another 2007study provided evidence that individuals with classic autism, a low-functioning autism spectrumdisorder, score higher in Ravens tests than in Wechsler tests. In addition, the individuals withclassic autism were providing correct answers to the Ravens test in less time than individualswithout autism, although erring as often.[3]John Carlyle Raven first published his Progressive Matrices in the United Kingdom in 1938. Histhree sons established Scotland-based test publisher J C Raven Ltd. in 1972. In 2004, HarcourtAssessment, Inc. a division of Harcourt Education acquired J C Raven Ltd.Notes 1. ^ Raven, J. C.
