Perceptual accent rating experiment: correspondence analysis graphically displaying the accent dispersion and associated accent ratings in a two-dimensional space. The points represent a vector transformation of the data displayed in Table 8. The blue circles represent the accent rating and the green circles represent the speakers. Ratings were defined as column points, speakers as row points. The distances between the scores and speakers represent the strength of association between both values. Both FAS and English are more closely associated with "Definitely non-native speakers of French" (=rating 1). French is (correctly) associated with "definitely a native speaker of French" (=rating 7).

Table 8). The native French-speaking control was most strongly associated with French-speaking "nativeness" (Figure 1).
Graphic representation of the stratification of the different native languages which 13 native French-speaking raters associated with the stimuli for the FAS patient and each of the control speakers. The FAS speaker was associated with 14 different accents including French. However, comparison of the FAS patient with the native French-speaking control clearly demonstrates that the raters identified the control's accent as their own in 95% of the stimuli versus a mere 24% for the FAS patient (see Accent Attribution Results).

French (score <7 on the rating scale) (Table 9). Figure 2 graphically displays the accent attribution of the 13 raters for all 15 stimuli per speaker (195 stimulus judgments per speaker). Accent attribution was most stratified in the Chinese speaker, her utterances being associated with no less than 15 possible languages (see Figure 2).
