The study requires 50 infant videos (25 male, 25 female) which will be used as stimuli in another study in which male participants will rate their emotional reaction to the cries. The goal of this project is to examine the influences of visual and acoustic qualities of infant cries on men’s perception of infant characteristics. In addition, we will explore if visual and acoustic qualities of infant crying vary based on infant sex. We have already collected enough videos of male infants, so are now only seeking videos of female infants who are 4 months or younger.
Crying is a pre-verbal child’s primary means for eliciting parental care, and evolutionary processes have shaped infant crying to influence parental behavior through negative reinforcement, with parental caretaking behavior leading to reduction of the aversive cry stimulus, thus leading to increased caregiving over time. While largely effective, crying is also a known trigger of shaken baby syndrome and other types of fatal child assault. Men are disproportionately responsible for committing abuse and infanticide and for this reason it is crucial to identify factors that influence men’s frustration and aggression. In addition, when abuse occurs it is perpetrated more frequently against male infants, a disparity that has yet to be explained. Previous experiments in our lab have suggested that male infants may possess unique qualities when crying that are perceived as aversive by male observers. In this experiment, we hope to expand upon this finding with a larger sample of stimuli and more precise recordings of observer reactions.

30 minutes total, 1 session
This study will involve you dressing your infant in a white diaper and laying him or her on a white blanket. You will then record a 40 second videos as s/he cries. The videos will be used as stimuli in another study in which participants will rate their emotional reaction to the cries. You are being asked to volunteer because you have a female infant 0-4 months of age. The total time required for you to complete this study is approximately 30 minutes. In the second phase of this study, visual analyses will quantify infant motion and expressions and acoustic analyses will measure a wide range of auditory cry qualities.
