Intentions : « In the present study we investigated parental preference for sons in Canada through the content analysis of birth announcements published in Calgary and Montreal newspapers. » (p. 408)
Questions/Hypothèses : « It was hypothesized that parents would more frequently report pride in relation to boy babies than girl babies. We expected reports of happiness to be similar for the birth of a boy or a girl. These two hypotheses were also tested by analyzing parental expression of emotions at the birth of a second child. » (p. 408)
Échantillon/Matériau : « A total of 192 announcements (101 of girls and 91 of boys) from The Gazette and 194 (93 of girls and 101 of boys) from the Calgary Herald were selected for the study. » (p. 408)

« Content analysis of birth announcements was used as a method to investigate parental preference for the sex of newborns in Canada. The expression of positive affect (happiness and pride) in birth announcements was examined to determine whether parents express these emotions differently as a function of the sex of newborn. The findings suggest that parents express relatively more pride at the birth of boys than girls, whereas the opposite results were found for happiness. Parents seem unconsciously to categorize boys and girls into two distinct motivational systems: status and attachment, which are related to pride and happiness, respectively. This distinction may influence parents’ perception of their child’s worth and their subsequent investment in their child’s development. » (p. 407)

Type de traitement des données : Analyse statistique
« The objective was to elicit the mental representations about the sex of the future child of 89 nulliparous pregnant women who declared having no sex preference, using the Kelly’s Repertory Grid. Analyses showed that 67% of these women had no explicit and clear representation about the sex of their child. These data suggest that these women seemed really to have no sex preference. » (p. 464)
