Subsequently each subject was given three problems corresponding to the content of the theree different rules (abstract content, thematic-premission and thematic-norm) and the instructions were also manipulated (verification/falsation vs. violation) (Valiña & cols., 1996). The results showed that: a) Performance in Wason´s selection task with abstract and thematic-permission content in terms of logical index is related to measures of the DAT-VR, b) In terms of differential analyses it was found that the logical index was considerably better in the higher reasoning-verbal group (DAT-VR) with abstract content and thematic-permission, but differences were not found in performance among good and por verbal comprehenders (PMA-V and Gernsbacher Comprehension Battery) or subjects with high and low scores in the PMA-R, and c) For he logical index and the matching index the principal effects of the content of the rule and the instructions were registered PB Universidade de Santiago de Compostela YR 1997 FD 1997 LK http://hdl.handle.net/10347/27087 UL http://hdl.handle.net/10347/27087 LA eng NO This work was presented at 10th EUROPEAN MEETING OF THE PSYCHOMETRIC SOCIETY, celebrated in Santiago de Compostela, Spain (15-18th July, 1997).  DS Minerva RD 28 abr 2026
