Men hunted and therefore required a greater level of spatial ability 29 30 5  8/17/24 Biological Explanations Biological Explanations The case of Bruce Reimer The case of Bruce Reimer 31 32 Environmental Explanations for Gender Differences 33 34 35 36 6  8/17/24 Math class is tough.

In this warmly humorous book, they tell each other why and conclude that the best reason of all is — because they need each other!” From the “Books for Children” section in Childhood Education, 1970: “Simple drawings with line captions designed to help the young child discover his or her appropriate sex role.” 49 50 Environmental Explanations Montemayor (1974) 6- and 8-year-old boys and girls were invited to play a game 51 52 How Much Did Children Like the Environmental Explanations Game? 6 Montemayor (1974) 5 6- and 8-year-old boys and girls were invited 4 to play a game 3 Game labeled as gender-appropriate, Boys gender-neutral, or gender-inappropriate 2 Girls 1 0 "Boys' Game" "Game" "Girls' Game" 53 54 9  8/17/24 How Well Did Children Play the Environmental Explanations Game? 12 Montemayor (1974) 10 6- and 8-year-old boys and girls were invited 8 to play a game 6 Game labeled as gender-appropriate, Boys gender-neutral, or gender-inappropriate 4 Girls Children found the game more enjoyable if 2 it was labeled as gender appropriate or neutral 0 "Boys' Game" "Game" "Girls' Game" 55 56 Environmental Explanations Environmental Explanations Much gender socialisation begins with a Montemayor (1974) child’s parents Children’s performance was highest when Morrongiello & Dawber (1999) the game was labeled as gender- appropriate and lowest when the game Examined mothers’ and fathers’ was labeled as gender-inappropriate communications to sons and daughters aged 2 to 4 years: – During free play – When teaching a playground safety behaviour 57 58 Environmental Explanations Average Frequency of Parent Verbalisations to Child 15 Mothers and fathers did not differ in their communications 12 Boys Girls Sons received more directives, fewer 9 explanations, and more physical pressure than girls 6 3 0 Caution Stop Encouragement 59 60 10  8/17/24 Environmental Explanations Environmental Explanations è Parents Smith & Lloyd (1978) communicate with young children in a Mothers of young infants introduced to a 6- way that may month-old infant and asked to play promote increased risk-taking by boys Infant’s gender label was manipulated and greater perceived vulnerability among girls BOY GIRL 61 62 Environmental Explanations Environmental Explanations Smith & Lloyd (1978) Smith & Lloyd (1978) Mothers of young infants introduced to a 6- è Even when there are no differences in month-old infant and asked to play appearance or outward behaviour, parents treat children according to gender label Infant’s gender label was manipulated Participants behaved differently according to the assigned gender label 63 64 Environmental Explanations Weisner & Silson-Mitchell (1990) Parents who do not subscribe to gender differences in socialisation have children whose attitudes and behaviour reflect fewer gender stereotypes 65 66 11
