their gender intensification hypothesis in that signals and messages from parents determine and affect their children's gender role identities. This hypothesis argues that parents affect their children's gender role identities and that different interactions spent with either parents will affect gender intensification. Priess and among other's study did not support the hypothesis of Hill and Lynch which stated "that as adolescents experience these and other socializing influences, they will become more stereotypical in their gender-role identities and gendered attitudes and behaviors." However, the researchers did state that perhaps the hypothesis Hill and Lynch proposed was true in the past but is not true now due to changes in the population of teens in respect to their gender-role identities. Authors of "Unpacking the Gender System: A Theoretical Perspective on Gender Beliefs and Social Relations", Cecilia Ridgeway and Shelley Correll, argue that gender is more than an identity or role but is something that is institutionalized through "social relational contexts." Ridgeway and Correll define "social relational contexts" as "any situation in which individuals define themselves in relation to others in order to act." They also point out that in addition to social relational contexts, cultural beliefs plays a role in the gender system. The coauthors argue that daily people are forced to acknowledge and interact with others in ways that are related to gender. Every day, individuals are interacting with each other and comply with society's set standard of hegemonic beliefs, which includes gender roles. They state that society's hegemonic cultural beliefs sets the rules which in turn create the setting for which social relational contexts are to take place. Ridgeway and Correll then shift their topic towards sex categorization. The authors define sex categorization as "the sociocognitive process by which we label another as male or female." The failure of an attempt to raise David Reimer from infancy through adolescence as a girl after his genitals were accidentally mutilated is cited as disproving the theory that gender identity is determined solely by parenting. Reimer's case is used by organizations such as the Intersex Society of North America to caution against needlessly modifying the genitals of unconsenting minors. Between the 1960s and 2000, many other male newborns and infants were surgically and socially reassigned as females if they were born with malformed penises, or if they lost their penises in accidents. At the time, surgical reconstruction of the vagina was more advanced
