Note: Cluster size in semantic fluency = words that share the same semantic subcategory (e.g., jata [cat], skilos [dog] in animals). Cluster size in phonemic fluency = words that begin with same first two letters (alepu [fox], alojo [horse]), words that differ only by a sound (çina [goose], çira [widow]), rhyming words (soma [body], stroma [mattress]). Switches = number of transitions between clusters.
