For this author, after reviewing all work related to the theme exposed to changing attitudes towards these students can perform the following activities: 1. direct or indirect contact of normal and mentally retarded students. Although distinction is made between structured experiences and not structured, resulting most successful in the former, i.e. in the structured experiences, however this does not ensure positive results, sometimes appearing attitudes to which you want to promote. 2 Information and persuasion. The experience carried out by Forade (1979) allows us to indicate that we would not be significant changes in the students. 3Rd simulation of handicaps. Here you can find various authors with contradictory conclusions; a favor, as performed by Clore and Jeffrey provided that prolong the simulation over a period of 4 months, or of Wilson and Alcorn, which found no significant changes.
