Most research works on language attitudes, which have been done within the Hispanic world, deal with issues where Spanish is usually confronted with other languages (American Indian languages, Catalan, Valencian, Galician, Equatorial Guinean languages, English, etc.), or about attitudes in some Spanish-speaking countries with respect to other varieties of Spanish, both in the Americas and Spain. However, a global, comprehensive study, which would include all Spanish speaking countries, and which would assess their attitudes, beliefs and prejudices equally, was missing, so that it would have been possible to count for a thorough and at the same time comparative study about how Spanish speakers evaluate not only their own speech, but the speech of others around them. The present study describes in broad strokes the most recent research and their new contributions in the Spanish-speaking world.
