abstract
On the Number of Handedness Groups There is a considerable debate among laterality researchers with respect to whether handedness is a continuous or categorical trait, and if the latter, how many handedness groups should be distinguished. This study addresses a statistical test of this issue. Finite mixture modelling was used to determine the number of handedness groups based on handedness data. Two datasets are used to present differences between the healthy population and patients with PD. Three handedness groups can be distinguished in both populations; however, the pattern of handedness is clearly different in patients with Parkinson's disease. Analýza latentních tříd dotazníků laterality Mezi odbornou veřejností se v posledních několika letech živě debatuje, zda-li je rukovost (handedness) svou povahou spíše intervalová či kategorická, a pokud kategorická, kolik skupin z hlediska rukovosti je vhodné rozlišovat. Tento článek řeší tuto problematiku ze statistického pohledu. Analýza latentních tříd je použita jako prostředek k testování počtu homogeních skupin z hlediska rukovosti. V empirické části jsou analyzovány a srovnávány datové soubory zdravé populace (n = 1526) a populace parkinsoniků (n = 476). Výsledky ukazují, že z hlediska rukovosti je u obou populací nejvhodnější rozlišovat 3 skupiny; nicméně interpretace těchto skupin je u populace parkinsoniků odlišná.
