Negative affectivity is a temperament dimension that is characterized by a child being easily upset (i.e., crying a lot, throws tantrums frequently) and having a hard time regulating their negative emotions. This is measured by the Early Childhood Behavior Questionnaire. The questionnaire has a summary score of 0 (low) - 30 (high). The average hypothesized negative affectivity score across samples is 10.20. "effortfulcontrol" = Effortful Control. Effortful control is a temperament dimension characterized by a child's ability to regulate their attention. This is also measured by the Early Childhood Behavior Questionnaire. The questionnaire has a summary score of 0 (low) - 30 (high). The average hypothesized effortful control score is 9.42. "weight1year" = child participant weight at 1 year old. This weight is given in pounds. The average child will weigh 21.37 pounds in the first year of life. You are a researcher who has collected this data.
