Muller-Lyer_illusion

The dataset provides data on cognitive and temperamental determinants of the Müller-Lyer illusion recorded in a group of 170 participants aged 20-33. The cognitive predictors included: the field dependent-independent cognitive style and the efficacy of attention networks: alerting, orienting, and executive control. The temperamental indicators were searched in the context of the Strelau’s Regulative Theory of Temperament. The results confirmed that susceptibility to the M-L illusion is associated with field dependence. Rhythmicity as a temperament trait moderated the relationship between susceptibility to the Müller-Lyer illusion and the efficacy of alerting. At a low level of Rhythmicity, a relationship between lower efficacy of the alerting network and higher susceptibility to the illusion was observed.
