And surprisingly, as children, we start out thinking more flexibly about gender than we end up.
Before the age of five, children don’t seem to think that gender has any permanence at all.
And they also prefer to engage with gender-stereotyped toys and activities.
It isn’t until a few years later – when they are between seven and 10 years of age – that children become more relaxed about maintaining behaviors that are strictly male or female.
For example, in a well-known study, psychologist Sandra Bem showed preschool-aged children three photographs of a male and female toddler.
In the first photo, the toddler was naked; in the second the toddler was dressed in gender-typical clothing (e.g., a dress and pigtails for the girl, a collared shirt and holding a football for the boy); in the third photo, the toddler was dressed in stereotypical clothing of the opposite gender.
For example, there are animals that don’t have sex chromosomes at all, and some species of coral reef fish can actually switch genders if their schools require it.
Alligators, crocodiles, turtles and some lizards don’t have sex chromosomes either: their sex is simply determined by the temperature of their nest during incubation.Sex doesn’t necessarily map to gender perfectly, and the environment plays a role in determining the gender of each person.Perhaps this shouldn’t be that surprising, given that the sex of many species of animals is determined by environmental circumstances and not by their biology.In most cases, XX chromosomes will become female and XY chromosomes will become male. Gender is what actually gets expressed – how we look, how we act and how we feel.While sex is determined by what is written into the chromosomes or what is dictated by our biology, known as genotype, it is the interaction between the genes (genotype) and the environment that determines gender.A preschooler might ask his female teacher whether she was a boy or girl when she was little, or a little boy might say that he wants to grow up to be a mommy.Tags: Adult Dating, affair dating, sex dating
