%A Professor Julio C Penagos-Corzo %A MD Alejandra Ciria %T Sex Differences in Subjective Estimation of Time During the Performance of Verbal and Spatial Tasks %X Differences between sexes in the subjective estimation of time when performing tasks of verbal fluency and mental rotation of 3-D images were studied in this research. 240 Mexican college students were divided in six groups; one male and one female group for each condition: Verbal, Spatial, and Control tasks. Subjects were asked to perform their corresponding task during two minutes which they had to estimate by themselves. No significant time estimation differences (p = .6913) between sexes were found when performing the verbal fluency task. However, significant time estimation differences (p = .0265) between the male and the female group were found with the mental rotation task. In addition, no significant time estimation differences between sexes were observed as for verbal fluency skills (p = .8265) and mental rotation (p = .4506). Results are discussed in terms of the evidence that shows that men have a higher activation in the right parietal region when performing mental rotation of 3-D images and estimating time prospectively. The way that different tasks affect the perceived length of psychological present depending on the cognitive processes used to perform each task is discussed as well. %D 2008 %K Subjective Estimation of Time, Time Perception, Verbal Fluency, Mental Rotation, Sex Differences %L cogprints7843
