Constituent frequency effects in the written production of Spanish compound words

Handwriting fluency, latency, and kinematic in Portuguese writing system: Pilot study with school children from 3rd to 5th grade

Studies have referred to the interaction between orthographic and motor aspects during the production of handwriting. However, studies with Brazilian Portuguese are still lacking. Hence, the aim of this study was to compare orthographic regularity, based on the Portuguese writing system, in high (HF) and low (LF) frequency words, in relation to latency and kinematic variables in students from the 3rd to the 5th grade of elementary school. This is a cross-sectional pilot study, with a convenience sample of 95 children participated in this study, from 3rd to 5th grade level attending a state elementary school. All were submitted to the following procedures of computerized evaluation of handwriting and submitted to the task of writing 15 HF and 15 LF words, selected according to the frequency criteria and classified according writing coding rule. Results indicated that for HF words, there was a decrease in writing and disfluencies production time, for all coding rules, from 3rd to 5th grade. However, for LF words, the more unpredictable orthographic affect production duration time, movement fluency, and students became more dependent on the use of gaze to check spelling aspects. This study revealed that lexical and sub-lexical activation affected motor production. For HF and LF words, lexical and sublexical process favored motor programming. However, for LF words, despite the maturation and school progression for the motor planes, there was an increase in latency time and in the need to search for word information, measured by the gaze variable for words with greater irregularity. This study has provided some evidence that linguistic variables such as orthographic regularity and word familiarity affect handwriting performance in Brazilian Portuguese written language.

Morphological processing in written word production is based on orthography rather than semantics

Written word production is influenced by central and peripheral processes. Evidence suggests that the activation of morphological units in the lexicon influences the dynamics of handwriting. In this study, we designed two priming experiments to examine the representation level of morphological information in the lexicon during written word production in the French language. In both experiments, target words (e.g., chanteur, "singer") were primed by a derived (e.g., chanter, "to sing"), a pseudo-derived (e.g., chantier, "work site"), or an unrelated (e.g., baleine, "whale") prime. We used the pseudo-derivation condition to disentangle two distinct levels of representation: the sublexical (also known as morpho-orthographic) and the supralexical (morpho-semantic). In Experiment 1 (learning-recall task), we measured the writing latency and writing duration of the target words. In Experiment 2 (word pair copying task), we measured the inter-word duration and writing duration of the target words. We observed morphological priming effects in both experiments: The processing of a derived prime influenced target writing compared to an unrelated prime, but the effect was observed on latencies in Experiment 1 and on target writing duration in Experiment 2. We found similar patterns of priming in the derived and pseudo-derived conditions in both experiments. The findings revealed that morphemes are processed at the morpho-orthographic representation level in written word production. Morphemes serve as grouping units during handwriting, a process that operates independently of their meaning.

Psycholinguistic norms for a set of 506 French compound words

Compounds are morphologically complex words made of different linguistic parts. They are very prevalent in a number of languages such as French. Different psycholinguistic characteristics of compounds have been used in certain studies to investigate the mechanisms involved in compound processing (see Table 7). We provide psycholinguistic norms for a set of 506 French compound words. The words were normed on seven characteristics: lexeme meaning dominance, semantic transparency, sensory experience, conceptual familiarity, imageability, age of acquisition (AoA) and subjective frequency. Reliability measures were computed for the collected norms. Descriptive statistical analyses, and correlational and multiple regression analyses were performed. We also report some comparisons made between our normative data and certain norms obtained in other similar studies. The entire set of norms, which will be very useful to researchers investigating the processing of compounds, is available as Supplemental Material.
