| summary | In this talk, I will introduce the DeveL project that was launched in order to investigate how visual word recognition processes develop and change across the lifespan.
To this end, we selected 1152 German words according to specific linguistic characteristics that are considered crucial in developmental theories of written language acquisition. These words were presented to 420 students of grades 2, 4, and 6 in computerized single sessions. In addition, data from 40 younger (20?30 years) and 40 older adults (65?75 years) were assessed. Word recognition performance was measured using the lexical decision and the naming task. To investigate the impact of interindividual differences on processing, we also measured participants? reading speed, vocabulary knowledge, and non-verbal intelligence.
In this talk, I will examine how the effects of important word characteristics (e.g., word length and frequency, orthographic neighbors) are moderated by participants? age and reading skills. In addition, I will report results from simulations using the CDP+ model to further investigate the cognitive locus of these developmental changes and address the question whether they can be accommodated within a single structural architecture.
Data from the DeveL project will be made available to the scientific community using an online database, which allows to refine existing models of visual word recognition by conducting virtual experiments. |
