Comparing phonological similarity between twin and non-twin siblings
Ingram, Dubasik, Liceras & Fernández Fuertes (2011) developed a measure of phonological similarity that compares phonological samples across 4 levels (whole words, word shapes (syllables), consonant inventories, consonant correctness), using 9 measures in total. The present study used the similarity measure to compare 4 dyads of children: identical twins, non-identical twins, non-twin siblings born 2 years apart, non-twin siblings born 5 years apart. Results indicated that phonological similarity decreased across the 4 dyads, providing evidence for genetic and environmental effects. The differences across dyads varied by phonological level, thus, indicating the importance of conducting multi-dimensional phonological analyses.
