In early childhood, gender roles become apparent in patterns of play. Hardy et al. (2009) addresses the differences among preschool boys and girls in their development of fundamental movements. This time period is especially crucial because if a child's fundamental movement skills do not develop properly, then their future development will be drastically impacted. This study took 425 preschool children and asked them to perform specific fundamental movement skills such as locomotor and object control skills. After examining the children performing these movements, the researchers found that female preschoolers are generally better at locomotor movements, while male preschoolers are better at object control. These findings emphasize the need for a superior program in which boys and girls can work together and integrate their skills for a chance at greater development of future skills. One of the earliest signs of gender differences in play patterns is the appearance of gender-segregated play groups and toy preferences. It's important to highlight the role that age plays in toy preference. In a study the children were given gender-type toys and their findings concluded that for boys at 17 months, 25% of these children used gender labels and by 21 months 68% used these gender labels, while girls tend to use more gender labels by 18 months. In addition, boys tend to gravitate more towards toys such as trucks while girls tend to gravitate towards dolls, but these preferences are not absolutes. A study by Alexander, Wilcox, and Woods showed that female infants showed more visual interest in a doll over a toy truck while male infants showed more visual interest in a toy truck over a doll, but these differences were more pronounced in the females. This study suggests that preferences for feminine or masculine toys precede any sex differences in the perceptual features of such toys, leading to the assumption that gender-based toy preference is innate. One of the most compelling theories regarding biologically determined
gender differences is the idea that male-preference and female-preference for toys are mediated by inequities in
visual processing. The central claim is that males and females are preprogrammed to specialize in certain forms of perception: specifically, perception of motion and perception of form and color, respectively. Alexander (2003) makes a particularly strong case. The author suggests that inherent sex differences based on perceptual categories encourage children to seek out playmates of a similar play style, and ultimately predisposes them for later social and gender roles. Human vision operates based on two anatomically grounded systems: the
magnocellular pathway (M-cell) and the
parvocellular pathway (P-cell). Both pathways are present in males and females, and M-cells are designed to recognize motion, while
P-cells specialize in form and color perception. Some research has suggested that sex-linked differences in M-cell versus P-cell dominance could be the underlying factor leading to differential toy preference in children, potentially validating the stereotype that boys prefer toy cars and balls (objects associated with motion) while girls prefer dolls and stuffed animals (objects characterized by distinct facial characteristics, form, and color). Beyond hormonal explanations, Alexander (2003) also employs an evolutionary biology perspective to link contemporary toy preference to early selective pressures and the development of visual specialization. Specifically, male M-cell pathway dominance is connected back to motion mediated activities like hunting and the throwing of projectiles. Female P-cell dominance is tied to foraging for plants, a task requiring discrimination between colors and memory of form. Color is particularly important in foraging, as discrimination between colors aids in identifying a ripe piece of fruit from the greenery around it. As it were, the "green-red opponent system" is thought to be X-chromosome linked and phylogenetically more recent, in contrast with the more rudimentary "yellow-blue" system present to the same degree in both sexes. According to the theory, this adaptation has persisted throughout human evolution, and may contribute to contemporary sexual-dimorphism in skill and preference. From this position, Alexander (2003) suggests the designation of pink as a girl color and blue as a boy color might not be completely arbitrary after all. In a separate study by Gredlin and Bjorklund (2005), it was found that there are sex differences in object manipulation. An experiment was performed by putting a desirable toy in an out-of-reach place, but also giving the child 5 different tools he/she could use to help retrieve this object. The children were put in these conditions and any decision they made was spontaneous and on their own; they were only given a hint after they had failed the task 5 times. The study's results showed that 77% of the boys used one of the tools to reach the toy, while only 31% of the girls used one of the tools. This shows that boys are more likely to participate in object manipulation, and this may be because they spend more time in object-oriented play. The study also found that girls spend more time in social play. Evolution may play a role in this phenomenon; the differences in play styles between boys and girls manifest into adult behavior. Another study by Alexander and Saenz found that two-year-old girls preferred toys that were typically associated with females over those associated with males, but again, two-year-old boys showed only a small preference for masculine toys over feminine toys. These two studies support the notion that toy preferences, while gender-based, are not a perfect indication of gender identity. Further, a study by Jadva, Hines, and Golombok showed that while male and female infants show more visual attention towards toys specific to their gender, there is no significant sex difference in color or shape preference at a young age, which suggests that, for example, a preference for the color pink in girls stems more from societal norms than from an innate capacity. Play differences are not concrete, as mentioned, as some play with "other-gendered" toys is quite common. Ruble and Martin showed that there is often cross-gendered play in boys and girls, and this is typical of development. However, it is hypothesized that atypical gendered play patterns, such as a boy who plays almost exclusively with dolls and not typical masculine toys and who prefers to play with girls over boys, are an indication of later homosexuality. Lobel & Menashri (1993) explore how the rigidity of
gender schemas guides behavior. The population of interest consisted of
preschool children selected from three different preschools in Tel-Aviv, Israel, and the study focused on the relationship between the children's gender-typed toy choice, their frameworks regarding cross-gender behavior, and their concepts of gender constancy. During the procedure, two feminine and two masculine toys were presented to individual children: a visibly new doll, a tattered, old doll, a shiny new truck, and an old, faded truck. Based on a pretest, the dolls and trucks were clearly recognized as feminine and masculine, as well as attractive and unattractive based on their quality. All children preferred the new toy when presented with a pair of singularly gendered toys. Children were first given a toy preference test, then a gender constancy interview, and then a gender-role norms interview. The results indicate that children with a more flexible view on gender-role norms made fewer gender-typed choices than children with rigid norms. Similarly, for children with more flexible gender norms, attractiveness of the toy proved to be more strongly related to preference than the toy's adherence to a traditional gender-role. This result raises the question: from where does this flexibility in gender behavior come? The authors favor the explanation that parental norms play a large role, but insist that further research must be done. Echoing Serbin et al. (2001), they also assert that a certain level of cognitive ability must be reached in order to demonstrate flexibility in gender roles, otherwise conceptions of fundamental gender constancy could become confused with external objects associated with a traditional gender role. Besides play patterns being an indication of sexual orientation, the presence of homosexual or heterosexual relationships in the family may in turn influence play patterns in children. It has been suggested that children of same-sex couples are raised differently, resulting in gender roles different from those of heterosexual parents. This viewpoint is validated in a recent study by Goldberg, Kashy, and Smith, which showed that sons of lesbian mothers were less masculine in the way in which they played than those of gay fathers or heterosexual parents. While this study supports one viewpoint on the effects of same-sex parenting, further research is required to validate the long-term consequences of homosexual parenting. In a 2015 study, it was found that children over the age of two show a stronger preference for the color of an object, as opposed to what the object was. The child was more interested in toys that were gender-traditionally colored, regardless if that toy was a toy typical for their gender. Due to the separation of toys advertised, or colored, for certain genders, it can hinder cognitive and
social skills. Boy oriented toys focus on spatial skills, and girl oriented toys focus on social or verbal skills. In solitary play, both girls and boys are more likely to play with gender typical toys, but as found by Signorella (2012), but in group play, gender neutral activities were more likely. == Friendships and schooling ==
