Early Contributions to Infants’ Mental Rotation Abilities Article
In Constantinescu et al. (2017) article, the study focuses on the parental perspective on gender differences and early postnatal testosterone levels. The research used an explanatory and experimental design. This study measures the salivary testosterone and mental abilities in healthy newly born infants. The infants’ mental capacities and the parents' notions of gender are analyzed in this research. Saliva samples were obtained to quantify the testosterone levels in infants between the ages of 1 month and 2.5 months and 5 to 6 months old.
The participants were 61 healthy infants: Twentynine males and 32 females. Of the parents, there were 59 moms and 32 fathers, with one infant having both parents participate in the survey. These participants were selected from Cambridgeshire, UK. Infants' ages in this study ranged from 29 to 71 days at the first trial duration and 145 to 1981 days for the second trial. The study recorded that none of the infant's parents had any hearing or seeing challenges. Saliva samples from the parents were collected, and their gender orientation was recorded using the child gender and socialization scale.
Constantinescu et al. (2017) completed the study with accurate findings after employing various scopes. The study's first finding shows proof of a connection between the concentration of testosterone during early postnatal stages and later mental rotation performance in boys. The second is the principal study to give proof of the potential impacts of parental perspectives on the mental rotation of infants in girls. The third result is proof of an early postnatal surge in testosterone levels in saliva instead of blood or urine tests.
