Two experiments are described in which subjects were required to report the name of a single position-cued ‘critical’ letter in a tachistoscopically displayed string of four letters. The stimulus characters were arranged to form three types of letter strings: (i) strings in which the letters did not form words; (ii) words in which contextual constraint of the critical letters was minimised; and (iii) words in which contextual constraint of the critical letters was maximised. The serial position of the letter to be identified in each string was cued at delays of −500, −100, and +500 ms, in experiment 1 and at delays of −510 and +510 ms in experiment 2, and in both experiments one group of subjects responded to letter strings which subtended a horizontal visual angle of 3·95 deg, while a second group responded to strings which subtended 1·02 deg. Correct identifications of critical letters showed that the presentation of words resulted in superior performance. This ‘word superiority effect’ is consistent with earlier findings implying that it has a perceptual locus. For the stimuli which subtended the large visual angle the word advantage was detrimentally affected only when the position of the critical letter to be identified was cued either 500 or 510 ms prior to the display of the letter string.

The question of whether intonation contours directly signal meaning is an old one. We revisit this question using vocatives in Colombian Spanish (Bogotá). We recorded speakers' productions in three pragmatic conditions – greeting, confirmation-seeking, and reprimand – and compared proper names (vocatives) to situation-specific one-word utterances, such as¡Hola!‘Hello’ (non-vocatives). Intonational analyses showed no direct one-to-one correspondence between the pragmatic conditions and intonation contours: (a) for vocatives, e.g. a rising–falling contour occurred in both greetings and reprimands; and (b) for non-vocatives, e.g. a step-down contour (a.k.a. calling contour) occurred in both greeting and confirmation-seeking conditions. Looking beyond intonation to consider other phonetic variables – spectral tilt, duration, alignment of tonal targets, f0-range, f0-slope – the results showed that the intonation contours that occurred in more than one pragmatic condition differed in phonetic realisation, e.g. rising–falling vocatives showed differences in f0-range of the rise and spectral tilt. However, the corresponding non-vocatives did not show the same differences. Furthermore, vocatives in greeting contexts were realised differently from non-vocatives in greeting contexts. In sum, the pragmatic condition affects the prosodic realisation of (non-)vocatives, but the relationship is complex. The results are discussed in the light of prosodic constructions, leading to the conclusion that the prosodic realisation of vocatives and non-vocatives in Bogotá Colombian Spanish cannot be easily modelled by prosodic constructions.
