Sex, sexual orientation and sex hormones influence human cognitive function

Sex, sexual orientation and sex hormones influence human cognitive function
Doreen Kimiira ( Canada )

Superior performance by women on a task requiring object location memory has challenged the traditional view that men excel on all spatia l tasks. Sexual orientation is also associated with variation in cognitive ability pattern, but such association appears to be more consistent for a real-world ten-getting task than for paper-and-pencil spatial tests. Finally, there is increasing evidence that early exposure to sex hor- mones has lasting effects on problem-solving behaviour; more over, current fluctuations in sex hormones in both men and women are associated with changes in cognitive pattern.
