Sex DIfferences - Halari et al replication Essay

Stephen Jay Gould, a paleontologist and evolutionary scientist, in his essay “Women’s Brains” (1980), argues that previous claims about the intellectual superiority of men over women are based on misinterpreted experimental results and therefore hold no scientific significance.

In the research done on “Sex Roles, Pink or Blue: Environmental Gender Stereotypes in the First Two Years of Life,” by Andree Pomerleau, Daniel Bolduc, Gerard Malcuit, and Louise Cossette at the University of Montreal stated that the physical environment of girls and boys will have an impact on the development of specific abilities and activities in children. In the research, three age groups were investigated and given types and colors of toys and have determined that boys prefer sports and large and small vehicles while girls had more dolls and fictional characters. The research proves that boys are more active and aggressive than girls. The research shows that as early as 18 months of age, children are already predisposed by sex stereotypes by their parents.

Differences related to gender in spatial memory are most widely described and studied of cognitive sex differences. In 1974 Maccoby and Jacklin established that males usually perform better than females in measures of spatial performance, and this discovery has been constantly replicated in multiple studies covering various developmental stages (McGivern et al. 1997; Lewin et al. 2001) and spatial tasks (Dabbs Jr. et al. 1998; Driscoll et al. 2005).

Craig’s worries about his son’s actions being more feminine as a result of playing with feminine toys is not uncommon. Many parents may become worried if they start seeing their child being more interested in playing with toys designed for the opposite gender. A hypothesis can be drawn up by stating that if boys with typically female toys, then there would be an increase of femininity traits of passiveness.

However in regards to general results between both genders it was shown that no definite statistical mean yielded notable results (Alansari & Baroun, 2004). Stroop (1935) also showed that women college students also showed a difference when compared to the men and tended to have higher word reading results, but in regards to the genders showed no significant differentiation between both at the cognitive level.

Infants of both genders have the same capacity for proficiency in math, but as they get older, more barriers seem to appear, which separate the results of males and females (Spelke). Women have one major barrier that men do not have: their responsibility to bear children and tend the household. This lead some females to believe that they do not have to excel in math and science fields, or at school in general, because they will one day stay at home and take care of their children and family. While women must focus on both their family and their studies, men can work and study without this pressure (Sternberg). Researchers have identified other differences between males and females, including advanced spatial skills in males and superior verbal skills in females (Spelke). The studies collected, however, do not supply sufficient information on gender differences, and therefore lack enough data to support any findings

In her scientific work Sex Differences in the Brain Kimura analysis several key differences that cause men and women to excel in various tasks and jobs due to naturally occurring phenomenon in the body and

Some of these gender roles and stereotypes have been created due to the differences in physique, thinking, personality, and behavior that is actually present between men and females. Physical differences are more visible to the eye due to the distinction between primary and secondary sex characteristics for each gender. Males have testes, deeper voices, a bigger body type, and more facial hair, where as women have a smaller body, higher voices, ovaries, and wider hips. (Rathus, 2010, p.448). Cognitive differences have to do with the brain and the way men and women

​Historically, men have displayed a stronger spatial memory than women ("Sex Differences in Memory"; Loftus et al. 82). What this means is that men are generally better at remembering things such as where the car is parked, driving directions (Loftus et al. 71) and, as exemplified in "Sex Differences in

Gender role is defined as the socially constructed and culturally specific behavior and appearance expectations imposed on women (femininity) and men (masculinity). Many girls are subjected to gender role stereotyping and different treatment Through socialization, individuals learn to behave in accordance with the expectations of others in the social order (Hult, 83.). Gender ideology is involved when one attaches a color such as pink and blue to sex and when one designates types of toys as male, female or neutral. Most play behavior is an outcome of gender role stereotyping that stems from cultural ideology. Early research provides that by first grade, boys recognize sports, whereas girls recognize grades

Glass begins with a prearranged true-false quiz which shows how many of our preconceived biases about differences between the sexes and how they communicate are actually false (Glass, 1994). Glass (1994) states that women are not statistically shown to be more intuitive than men. However, they have been discovered to be more detail oriented in both their

In her paper on the biological differences in cognition between men and women, Doreen Kimura suggests that the social differences between genders arose out of biological necessity (Kimura 46). Even so, it is difficult to argue that social factors do play a large part in gender in society today. A closer look at both biological and social perspectives will reveal more about the processes that determine gender roles.

The nineteenth century saw the start of the scientific debate in which brain size was presumed to indicate intelligence. Which in turn lead some scientists to the conclusion that men, having on average a larger brain size than women, may be more intelligent.

No one would argue the fact that men and women are physically different. The physical differences are rather obvious and most of these can be seen and measured easily. Men, who are essentially built for physical confrontation and the use of force, usually have greater upper body strength, build muscle easily, have thicker skin, and mostly use the left side of their brain. Women on the other hand, have a higher percentage of body fat, and a wider pelvis. Women also have four times as many brain cells connecting the right and left side of their brain. This provides physical evidence that supports the observation that men rely easily and more heavily on their left brain to solve one problem one step at

As evident from the generalized patterns found in differences in behaviour and outlook observed between the sexes, it may be tempting, as has been done in the past, to conclude that gender is an unavoidable aspect of human existence as determined purely from one 's genes. Indeed, human physiology is subject to sexual dimorphism; statistically significant differences in brain size and rate of maturation of specific substructures in the brain exist between males and females (Giedd, Castellanos, Rajapakese, Vaituzis, & Rapoport, 1997), yet these physical differences fail to explain how individuals form their concept of their own gender, and why they tend to conform to their perceived gender roles as defined by the society in which they live, when these roles are ever-changing. Thus, it is important to differentiate between the physical and nonphysical traits, and how the labels of femininity and masculinity should not confuse the two aspects. As defined by Unger (1979), “sex” would be used to refer to the biological differences in males and females, while “gender” describes socioculturally determined, nonphysiological traits which are arbitrarily designated as being appropriate for either females or males. With more recent awareness and interest in matters of gender nonconformity and individual gender identity, new research now explains how these concepts of gender are shaped by social influences (Perry
