Surprisingly, prefix position coding has not yet been assessed. This point is important given that some experimental studies demonstrated clear processing differences between prefixes and suffixes. In this study we examined whether Spanish suffixes and prefixes are recognized independently of their position by adapting the Crepaldi, Rastle, and Davis’s (2010) experimental paradigm. We observed that morphologically structured nonwords in which the affix occurs in its typical position (e.g., curiosura, disgrave) are rejected more slowly and less accurately than their matched orthographic controls (e.g., curiosula, dusgrave). Crucially, such morpheme interference effect is completely absent when the morphemes are inverted (i.e., uracurios and gravedis are rejected as easily as ulacurios and gravedus). Our ...

In the present experiment, the use of artificial elements that do not convey any particular meaning enables us to study separately the influence of the formai complexity of the sentence on the processing duration. The material is composed of embedded structures and passive forms. Some of these structures are isomorphic to natural language sentences. The results show that durations for processing artificial sentences are ordered in the same fashion as durations for processing natural sentences. The results validate a model of the subject based on relation operations and inversion operations.

The results indicated that these two variables introduced significant differences in the correct retention of word pairs and that their roles are additive. An interpretation was given in terms of implied linguistic rules.

This “syllable advantage” holds robustly for utterance-initial CV vs. C targets [Segui et al., 1981. Phoneme monitoring, syllable monitoring and lexical access. British Journal of Psychology, 72(4), 471–477]. We report a syllable advantage when monitoring inner speech. Spanish-speaking Argentinian participants presented with pictures were faster and more accurate at detecting CV than C targets at the beginning of the pictures’ names. This CV over C advantage maintained, although substantially weakened, after adding CV’ foils in CV-target trials, a manipulation logically more detrimental to CV- than C-detection. Our results converge with previous studies showing intriguing parallelisms between overt and inner speech perception and processing, supporting a restricted version of Levelt’s perceptual-loop hypothesis. We discuss what common basic units of processing could be, borrowing from the articulatory phonolo...

Comments are based on recent work carried out in the laboratory. The work presented is formulated from the outset on a “representational” level to characterize the mode of representation of morphological information in the mental lexicon. The lexical entries for derived words possess information concerning their whole word form. Information about the morphological structure of these words is reflected by the organization of the morphological family—that is, in the way in which the different items sharing the same “head” are related in the affix frame. The results obtained with experiments using priming methodology showed that morphological relations must be distinguished from orthographic relations. Morphological priming effects may not be the result of the conjunction of orthographic and semantic effects. The chapter examines the manner in which affixed words are recognized according to their morphemic structure.

In this study we examine the perception of a prothetic /e/ before word-initial #sC clusters by Spanish vs. French listeners, using gated stimuli derived from naturally produced /#as/+C and /#es/+C utterances. Spanish listeners but not French listeners heard a leading /e/ in the early gates where only a short portion or no trace at all of the original vowel was left. The extent of this effect was not modulated by how much ill-formed the /s/+C sequences were in terms of universal sonority contour preferences.

It also presents several studies that tend to show that the syllable operates as the basic speech processing device. If this assertion turns out to be true, it could have important implications. Some recent theories of lexical access, such as Marslen wilson's cohort theory, generally assume that left to right phoneme sequences determine not only how, but also when the listener can make an access to his lexicon. In the chapter's view, the syllable will turn out to be a much better device for computing cohort sizes than the left to right sequence of phonemes. Future work can test the different predictions that can be made on issues in lexical access. The chapter also considers the relative status of the phoneme and of the syllable in the course of language acquisition. Empirical studies will clarify whether such rules exist in infant language, and if so, how they are learned. If syllables are initially segmented into syncretic wholes, then in the course of development they probably will be analyzed and classified on the basis of their phonetic constituents. Thus, this achievement may, in part, be due to the contrast between speech perception and speech production.
