Adolescents' attitudes towards standard Galician, non-standard Galician and Spanish are examined in this study using a matched-guise test. Results show that adolescents perceive standard and non-standard Galician differently and that different values are attached to the three linguistic varieties investigated. Our findings confirm that certain stigmas are still attached to speaking non-standard Galician and to having a Galician accent when speaking Spanish. Finally, results provide evidence of gender-related trends in regard to standard and non-standard Galician, and also reveal a covert social disapproval of women.
