MorphoPlay – A Test of Morphological Processing for Developing Children


Morphological Knowledge is a cognitive process that enables speakers to recognize words as composed of smaller units of meaning. This process facilitates segmentation of words into these constituents, identification of relationships between words, and understanding of their grammatical functions. Morphological awareness enhances individuals' ability to manipulate and reflect on these morphological constituents. Accurate assessment of morphological awareness is crucial in identifying children with reading difficulties (Enderby et al., 2021; Levesque et al., 2021).
The primary objective of this project is to create a test that assesses morphological knowledge based on controlled items. The test will measure processing time and the percentage of correct answers and comprises four phases:
Firstly, building an experimental corpus of words that considers two derivational suffixes. This corpus will be controlled in terms of compositionality, number of syllables and characters, and frequency of occurrence. We will present the results of this phase and the game design.
Secondly, testing the corpus through a word association test on a sample of typically developing European Portuguese native-speaking children in 2nd, 3rd, and 4th grades.
Thirdly, applying a lexical decision test that will evaluate the reaction time to selected stimuli. This test will be applied to typically developing children (with identical inclusion criteria to the previous phase) and native European Portuguese-speaking children with previously diagnosed language disorders.
Finally, developing a game in mobile format to make the evaluation process more engaging and less artificial. This will ensure automatic monitoring of results, with access to scores and detailed error reports.
