The present study examined differences between inflectional and derivational morphology using Greek nouns and verbs with masked priming (with both short and long stimulus onset asynchrony) and long-lag priming. A lexical decision task to inflected noun and verb targets was used to test whether their processing is differentially facilitated by prior presentation of their stem in words of the same grammatical class (inflectional morphology) or of a different grammatical class (derivational morphology). Differences in semantics, syntactic information, and morphological complexity between inflected and derived word pairs (both nouns and verbs) were minimized by unusually tight control of stimuli as permitted by Greek morphology. Results showed that morphological relations affected processing of morphologically complex Greek words (nouns and verbs) across prime durations (50–250ms) as well as when items intervened between primes and targets. In two of the four experiments (Experiments 1 and 3), inflectionally related primes produced significantly greater effects than derivationally related primes suggesting differences in processing inflectional versus derivational morphological relations, which may disappear when processing is less dependent on semantic effects (Experiment 4). Priming effects differed for verb vs. noun targets with long SOA priming (Experiment 3), consistent with processing differences between complex words of different grammatical class (nouns and verbs) when semantic effects are maximized. Taken together, results demonstrate that inflectional and derivational relations differentially affect processing complex words of different grammatical class (nouns and verbs). This finding indicates that distinctions of morphological relation (inflectional vs. derivational) are not of the same kind as distinctions of grammatical class (nouns vs. verbs). Asymmetric differences among inflected and derived verbs and nouns seem to depend on semantic effects and/or processing demands modulating priming effects very early in lexical processing of morphologically complex written words, consistent with models of lexical processing positing early access to morphological structure and early influence of semantics.

Are words stored as morphologically structured representations? If so, when during word recognition are morphological pieces accessed? Recent masked priming studies support models that assume early decomposition of (potentially) morphologically complex words. The electrophysiological evidence, however, is inconsistent. We combined masked morphological priming with magneto-encephalography (MEG), a technique particularly adept at indexing processes involved in lexical access. The latency of an MEG component peaking, on average, 220 msec post-onset of the target in left occipito-temporal brain regions was found to be sensitive to the morphological prime–target relationship under masked priming conditions in a visual lexical decision task. Shorter latencies for related than unrelated conditions were observed both for semantically transparent (cleaner–CLEAN) and opaque (corner–CORN) prime–target pairs, but not for prime–target pairs with only an orthographic relationship (brothel–BROTH). These effects are likely to reflect a prelexical level of processing where form-based representations of stems and affixes are represented and are in contrast to models positing no morphological structure in lexical representations. Moreover, we present data regarding the transitional probability from stem to affix in a post hoc comparison, which suggests that this factor may modulate early morphological decomposition, particularly for opaque words. The timing of a robust MEG component sensitive to the morphological relatedness of prime–target pairs can be used to further understand the neural substrates and the time course of lexical processing.

Semantic transparency has been in the focus of psycholinguistic research for decades, with the controversy about the time course of the application of morpho-semantic information during the processing of morphologically complex words not yet resolved. This study reports two masked priming studies with English - ness and Russian - ost’ nominalisations, investigating how semantic transparency modulates native speakers’ morphological priming effects at short and long stimulus onset asynchronies (SOAs). In both languages, we found increased morphological priming for nominalisations at the transparent end of the scale (e.g. paleness – pale) in comparison to items at the opaque end of the scale (e.g. business – busy) but only at longer prime durations. The present findings are in line with models that posit an initial phase of morpho-orthographic (semantically blind) decomposition.

Do properties of individual languages shape the mechanisms by which they are processed? By virtue of their non-concatenative morphological structure, the recognition of complex words in Semitic languages has been argued to rely strongly on morphological information and on decomposition into root and pattern constituents. Here, we report results from a masked priming experiment in Hebrew in which we contrasted verb forms belonging to two morphological classes, Paal and Piel, which display similar properties, but crucially differ on whether they are extended to novel verbs. Verbs from the open-class Piel elicited familiar root priming effects, but verbs from the closed-class Paal did not. Our findings indicate that, similarly to other (e.g., Indo-European) languages, down-to-the-root decomposition in Hebrew does not apply to stems of non-productive verbal classes. We conclude that the Semitic word processor is less unique than previously thought: Although it operates on morphological units that are combined in a non-linear way, it engages the same universal mechanisms of storage and computation as those seen in other languages.

ABSTRACTThis study examined the processing of derivational morphology and its association with measures of morphological awareness and literacy outcomes in 30 Dutch-speaking high-functioning dyslexics, and 30 controls, matched for age and reading comprehension. A masked priming experiment was conducted where the semantic overlap between morphologically related pairs was manipulated as part of a lexical decision task. Measures of morphological awareness were assessed using a specifically designed sentence completion task. Significant priming effects were found in each group, yet adults with dyslexia were found to benefit more from the morphological structure than the controls. Adults with dyslexia were found to be influenced by both form (morpho-orthographic) and meaning (morphosemantic) properties of morphemes while controls were mainly influenced by morphosemantic properties. The reports suggest that morphological processing is intact in high-functioning dyslexics and a strength when compared to controls matched for reading comprehension and age. Thus, reports support morphological processing as a potential factor in the reading compensation of adults with dyslexia. However, adults with dyslexia performed significantly worse than controls on morphological awareness measures.

ABSTRACTWe investigated whether children with dyslexia rely on derivational morphology during visual word recognition and how the semantic and form properties of morphemes influence this processing. We conducted two masked priming experiments, in which we manipulated the semantic overlap (Experiment 1) and the form overlap (Experiment 2) between morphologically related pairs of words. In each experiment, French dyslexic readers as well as reading-level matched and chronological-age matched children performed a lexical decision task. Significant priming effects were observed in all groups, indicating that their lexicon is organized around morpheme units. Furthermore, the dyslexics’ processing of written morphology is mainly influenced by the semantic properties of morphemes, whereas children from the two control groups are mainly influenced by their form properties.

Prime Target

Using a repetition priming paradigm, the interrelations between morphologically related words in the mental lexicon were examined in two experiments. In contrast to most previous studies, in which morphologically complex words occur as primes and stems as targets, derivationally and inflectionally complex forms were fully crossed in prime–target pairs. Experiment 1 showed asymmetries in the pattern of priming effects between different inflectional forms of German adjectives. Such asymmetries are problematic for any theory that assumes that all members of an inflectional paradigm share one entry in the mental lexicon. Experiment 2 contrasted derivational and inflectional variants of the same stems used in Experiment 1. Once again, there were same clear asymmetries in the pattern of priming effects. The implications of these results for models of lexical organization of inflectional and derivational morphology are discussed.

Speakers can transfer meanings to each other because they represent them in a perceptible form. Phonology and syntactic structure are two levels of linguistic form. Morphemes are situated in-between them. Like phonemes they have a phonological component, and like syntactic structures they carry relational information. A distinction can be made between inflectional and lexical morphology. Both are devices in the service of communicative efficiency, by highlighting grammatical and semantic relations, respectively. Morphological structure has also been studied in psycholinguistics, especially by researchers who are interested in the process of visual word recognition. They found that a word is recognized more easily when it belongs to a large morphological family, which suggests that the mental lexicon is structured along morphological lines. The semantic transparency of a word’s morphological structure plays an important role. Several findings also suggest that morphology plays an important role at a pre-lexical processing level as well. It seems that morphologically complex words are subjected to a process of blind morphological decomposition before lexical access is attempted.

Inhibitory masked priming effects in the lexical decision task (LDT) have been proven difficult to replicate. If these difficulties are due to individual differences in attention, introducing minor fluctuations in the temporal parameters of prime-target presentation should increase priming effects by drawing attention to the prime. The current study presents two experiments in which we manipulated the duration of prime presentation to this effect. In Experiment 1, we presented subjects (n = 224) with an LDT using form-related and -unrelated word primes. Subjects were assigned to a condition in which all primes were presented for 48ms, or a condition in which one-fourth of the primes were presented for 64ms. Inhibitory priming effects emerged only for the mixed duration condition. Experiment 2 repeated the procedures of the first experiment but with nonword primes. Because nonword primes have no lexical information, target item response latencies should not suffer from the additional processing time required to suppress those representations. Thus, as predicted, Experiment 2 yielded a facilitatory effect of priming. Together, these experiments show that small manipulations of the prime SOA can increase attention to the temporal location of the prime, and that when attention is drawn to the existence of primes in this manner, inhibitory word priming can be observed.

This work aimed to investigate grapheme coding during sub-lexical processing and lexical access. Using the letter detection task in Experiment 1, we compared letter pairs that could be considered as a grapheme unit or not depending on context (referred to as weakly cohesive complex, e.g., an in chant vs cane) to real two-letter graphemes (highly cohesive complex, e.g., au in chaud) and single-letter graphemes (simple, e.g., a in place). Three experimental conditions were used, one of which was designed to prevent phonological influences. Data revealed that only highly cohesive complex graphemes were processed as units, not the weakly cohesive ones. The same pattern was found across experimental conditions in favor of an orthographic mechanism. In Experiments 2 and 3, a primed lexical decision task was used with two stimulus onset asynchronies (SOAs) and two different ranges of lexical frequency. We manipulated the number of graphemes removed from partial primes ( d**che vs do**he-DOUCHE) and relatedness. In contrast to Experiment 1, no evidence was provided in favor of a role of graphemes during lexical access. We suggest that graphemes can be conceived as sub-lexical orthographic units per se but can only be captured within a sub-lexical route to reading.

Considerable behavioral research has demonstrated that the visual word recognition system is sensitive to morphological structure. It has typically been assumed that analysis of morphologically complex words occurs only when the meaning of these words can be derived from the meanings of their constituents (e.g., hunter = hunt + er). However, results from recent behavioral research using the masked priming technique have demonstrated that morphological analysis can occur at an earlier orthographic level, in cases in which the meanings of complex words cannot be derived from their constituents (e.g., corner = corn + er). Here, we combine the logic of behavioral masked priming with the neurophysiological phenomenon of functional magnetic resonance imaging priming suppression to look for evidence of nonsemantic morphological priming at the neural level. Both behavioral and functional magnetic resonance imaging results indicated priming effects associated with the mere appearance of morphological structure (corner—CORN). In addition, these effects were distinguishable from lexical-semantic effects (bucket—PAIL) and orthographic effects (brothel—BROTH). Three left-lateralized occipito-temporal regions showed sensitivity to early morphological components of visual word recognition. Two of these regions also showed orthographic priming (∼BA 37, peak: −48 −60 −17; ∼BA 19, peak: −40 −77 −1), whereas one was sensitive only to morphological similarity between primes and targets (∼BA 19, peak: ∼37 ∼67 ∼7). These findings provide a neurobiological basis for a purely structural morphemic segmentation mechanism operating at early stages of visual word recognition.
