TY - JOUR A1 - Ciaccio, Laura Anna A1 - Veríssimo, João T1 - Investigating variability in morphological processing with Bayesian distributional models JF - Psychonomic bulletin & review : a journal of the Psychonomic Society N2 - We investigated the processing of morphologically complex words adopting an approach that goes beyond estimating average effects and allows testing predictions about variability in performance. We tested masked morphological priming effects with English derived ('printer') and inflected ('printed') forms priming their stems ('print') in non-native speakers, a population that is characterized by large variability. We modeled reaction times with a shifted-lognormal distribution using Bayesian distributional models, which allow assessing effects of experimental manipulations on both the mean of the response distribution ('mu') and its standard deviation ('sigma'). Our results show similar effects on mean response times for inflected and derived primes, but a difference between the two on the sigma of the distribution, with inflectional priming increasing response time variability to a significantly larger extent than derivational priming. This is in line with previous research on non-native processing, which shows more variable results across studies for the processing of inflected forms than for derived forms. More generally, our study shows that treating variability in performance as a direct object of investigation can crucially inform models of language processing, by disentangling effects which would otherwise be indistinguishable. We therefore emphasize the importance of looking beyond average performance and testing predictions on other parameters of the distribution rather than just its central tendency.

Baayen, Dijkstra, and Schreuder [(1997). Singulars and plurals in Dutch: Evidence for a parallel dual-route model. Journal of Memory and Language, 37, 94–117. doi:10.1006/jmla.1997.2509] proposed a dual-route model in which singular-dominant plurals (“brides”) are decomposed, while plural-dominant plurals (“peas”) are accessed as whole-word units. We report two lexical-decision experiments investigating how plural processing is influenced by participants’ age and morphological complexity of the language (German/Dutch). For all Dutch participants and older German participants, we replicated the interaction between number and dominance reported by Baayen and colleagues. Younger German participants showed a main effect of number, indicating decomposition of all plurals. Access to stored forms seems to depend on morphological richness and experience with word forms. The data pattern fits neither full-decomposition nor full-storage models, but is compatible with dual-route models.

Design/methodology/approach: We measured morphological priming effects for derived and inflected German words. To ensure that priming effects were genuinely morphological, the design also contained semantic and orthographic control conditions. Data and analysis: 40 native speakers of German and 36 native Russian learners of L2 German participated in a masked-priming lexical-decision experiment. For both participant groups, priming effects for derived vs. inflected words were compared using linear mixed effects models. Findings/conclusions: While first language (L1) speakers showed similar facilitation effects for both derived and inflected primes, L2 speakers showed a difference between the two prime types, with robust priming effects only for derived, but not for inflected forms. Originality: Unlike in previous studies investigating derivation and inflection in L2 processing, priming effects for derived and inflected prime-target pairs were determined on the basis of the same target word, allowing for a direct comparison between the two morphological phenomena. In this respect, this is the first study to directly compare the processing of derived vs. inflected forms in L2 speakers. Significance/implications: The results are inconsistent with accounts predicting general L1/L2 differences for all types of morphologically complex forms as well as accounts assuming that L1 and L2 processing are based on the same mechanisms. We discuss theoretical implications for L2 processing mechanisms, and propose an explanation which can account for the data pattern.

Yet, little is known about how this ability develops from child to adulthood. To gain insight into how children (in comparison to adults) handle different kinds of linguistic information during on-line language comprehension, the current study investigates a well-known morphological phenomenon that is subject to both structural and semantic constraints, the plurals-in-compounds effect, i.e. the dislike of plural (specifically regular plural) modifiers inside compounds (e.g. rats eater). We examined 96 seven-to-twelve-year-old children and a control group of 32 adults measuring their eye-gaze changes in response to compound-internal plural and singular forms. Our results indicate that children rely more upon structural properties of language (in the present case, morphological cues) early in development and that the ability to efficiently integrate information from multiple sources takes time for children to reach adult-like levels.
