COVRE, Priscila; MACEDO, Elizeu Coutinho de; CAPOVILLA, Fernando César  y  SCHWARTZMAN, José Salomão. Eye movements and scan patterns in mental rotation tasks. PsicoUSF [online]. 2005, vol.10, n.1, pp.41-49. ISSN 1413-8271.

The purpose of this paper is to identify the strategies used on mental rotation tasks by analyzing ocular movements. The performance of 40 participants on comparison of pairs of three-dimensional objects, rotated on the y-axis, from 0o to 180o was analyzed. An eye-tracking computerized system was used to track eye movements during scene visualization. Results showed that judgment time, fixation duration, number of fixations and number of switches between the objects increased with rotation angle. Analysis by visual inspection indicates the use of two kinds of strategies: Mental rotation around the standard axis and comparison of orientation-free descriptions. The use of the strategies is discussed with regard to performance and working memory.

Palabras clave : Mental rotation; Scan pattern; Eyegaze; Eyetracking.
