摘要：The aim of this investigation is to verify Kosslyn's hypothesis on different processing of two types of spatial relations, categorial and coordinate. The assumption is that a categorial relation would process faster and more accurately with the left hemisphere, while a coordinate relation would process faster and more accurately with the right hemisphere. Participants were 50 right-handed female students, average age 20 years. Two drawings of pairs of animals were presented consecutively to participants, the first one centrally, the second one laterally. Subjects had to answer if the two presented stimuli were the same or different by pressing the specified buttons. The results showed that categorial spatial transformation was recognized faster when presented in the right visual field compared to the left visual field, while coordinate spatial transformation was recognized faster when presented in the left visual field compared to the right visual field. Categorial spatial transformation was recognized faster than coordinate when presented in the right visual field. Categorial spatial transformation was generally recognized faster and more accurately than coordinate spatial transformation.
