Tämä tietty käyttäytyminen nähdään jo eläinmaailman tasolla tehdyissä kokeissa, missä urosapina valitsee auton, kun taas naaras suosii nukkea.

Näitä vervet-apinakokeita 2000-luvun alussa tehtiin ilmeisesti vain kaksi, johtopäätökset on siihen nähden vähän turhan grandioosit. Artikkeli vuodelta 2023: Monkeys do not show sex differences in toy preferences through their individual choices - Biology of Sex Differences
Background: As interest in evaluating sex differences in nonhuman animals grows, the finding that male and female monkeys have toy preferences that differ, and that parallel those documented in human children, has garnered significant attention and is leveraged as an argument in favor of a biological contribution for human sex differences. To date, however, only two studies have investigated sex differences in monkeys' toy preferences, both documenting that males prefer toys considered to be "masculine" (such as vehicles) and females prefer toys considered to be "feminine" (such as dolls). Monkeys in these studies were tested in their social groups, making it hard to determine if the sex differences reported reflect actual individual preferences or result from social dynamics present at the time of testing.

Conclusions
Our results contrast greatly with the previous study in rhesus monkeys, as well as findings in human children, suggesting that the previously documented sex differences are likely context dependent, and question the existence of a strong biological basis to sex differences in toy preferences.
Highlights
- When tested outside of their social groups, male and female rhesus macaques show no sex differences in their toy preferences.
- Males and females were both more likely to interact with neutral toys and “masculine” toys than with “feminine” toys and sex-ambiguous toys.
- When they interacted with toys, males interacted more with neutral toys than with “masculine” toys.
- When they interacted with the toys, females interacted more with neutral toys than with “masculine”, “feminine” or ambiguous toys.
- Only one between-sex difference emerged: when they interacted with it, males interacted more with the doll more than females did.
Mitä tästä voi päätellä? Tuskin mitään.
toiskohan joulupukki sellasen ihanan pehmoisen silmämaskin, ehkä niiden tarkoitus on helliä naisten silmiä kun he joutuvat lukemaan miesten aivoituksia.
