In Open Field studies with rats, why do male rats who have been separated for an hour or so a day from 2-13 days old behave more anxiously than female rats who were also separated?

I need an explantion that doesn't go into the details of the females cycle if possible.

Am no 'ratologist', but studies of Psychosexual Differences confirm that the male of the species is genetically immature, compared with the female. This is so from before birth until long, long after. Anaclytic Depression (from maternal deprivation) hits the males particularly. Ask any Mum about grizzy kids.

Prenatal slow genetic 'readout' is the cause. Slow development of males in most areas results. Virtually all areas of maturation are involved.

Very informative is Corinne Hutt's 'Males and Females'; (Penguin, 1972). Out of print, but obtainable on the web, esp. from USA.
