Building upon previous research on phonological templates, we explored how systematicity based on such templates, whether they encode meanings or not, influenced word learning in preschool-age Hebrew-speaking children. We examined form-meaning systematicity, where words share phonological templates and carry similar categorical meanings of manner-of-motion (e.g., <i>finupál</i> and <i>bizudáx</i> carry the meaning of skipping), and form-only systematicity, where words are phonologically similar but do not share a meaning (e.g., <i>finupál</i> and <i>bizudáx</i> belong to different categories of manner-of-motion). We aimed to discern how these systematicity types impact the learning of the meaning of the word as a whole, that is, the encoding of visual form combined with manner-of-motion. Using novel Semitic-like stimuli, our experiments demonstrated that different types of systematicity involve different effects on word learning. Experiment 1 showed that form-meaning systematicity hindered the learning of the manner-of-motion. In contrast, Experiment 2 revealed that form systematicity facilitated learning these features.

Termed child consonant harmony (CCH), this phenomenon has garnered considerable attention in the literature, primarily due to the apparent absence of analogous patterns in mature phonological systems. This study takes a close look at a potential account of CCH that is compatible with findings from adult word learning, serial recall, and phonological typology. According to this account, CCH is a response to memory pressure involved in remembering and retrieving multiple consonantal contrasts within a word. If this is the main motivation behind CCH, we would expect the resulting child forms to be biased toward full assimilation (i.e., consonant repetition) as it allows maximal reduction of phonolexical memory load. To test this prediction, children's productions of target words containing consonants that differ in both major place and manner were analyzed using two data sources: a single session sample from 40 children aged 1-2 years learning English, French, Finnish, Japanese, or Mandarin; and longitudinal samples from seven English-learning children between 1 and 3 years of age. Prevalence of consonant repetitions was robustly evidenced in early child forms, especially in those produced for target words with the structure CVCV(C).

Research on Hebrew language development suggests early sensitivity to frequently occurring templates. For the Arabic dialects, little is known about whether implicit sensitivity to non-concatenative morphology develops at a young age through exposure to speech, and how templatic the spoken language is in comparison to MSA. We focus on Lebanese Arabic. We hypothesized that prolonged contact with French and English may have \"diluted\" the salience of roots and patterns in the input. We used three different corpora of adult-directed-speech (ADS), child-directed-speech (CDS), and child speech. We analyzed the root and pattern structures in the 50 most frequent Lebanese Arabic word types in each corpus. We found fewer words with templatic patterns than expected among the most frequent words in ADS (35/50), even fewer in CDS (23/50) and still fewer in the children's target words (15/50). In addition, only a minority contains three root consonants in their surface forms: 22 in ADS, 15 in CDS, and only 7 in words targeted by the children.

An error analysis revealed small differences in children's use of experiencer and conditional constructions. Contrary to expectations, Norwegian-speaking bilinguals did not produce more errors of omission than of commission in either sentence type. Rather, they used a wider array of cases in the experiencer clauses than Russian-speaking children.

Four databases consisting of the productions of children (<i>n</i> = 74), aged 1;11 to 4;9, were analyzed.

Using mixed-effects logistic regression, we examined whether phonological complexity as determined by the IPC, WCM, or by alternative indices better accounts for the influence of complexity on production. We also investigated whether the accuracy of a target sound/structure was influenced by a word's complexity. Results indicated that complexity based on the IPC or WCM significantly influenced consonant accuracy; however, indices tapping fewer features provided superior model fit. At younger ages, the presence of fricatives/liquids and, at all ages, the presence of alveopalatal fricatives, codas, and clusters significantly influenced accuracy.
