Mathematical Model of Children's and Adults Memory Due to Stress

Weibull distribution is a well-known, common distribution. A new distribution of weibull is used in this paper, namely, weighted weibull (WW) and it is obtained by introducing a skewness parameter to a weibull distribution. In the application part, we discussed about whether Cortisol reactivity to a stressful situation was connected to children's memory and also that to adults memory. 9 to 12-year olds were selected for this study. They were completed an impromptu speech and math task during which repeated cortisol samples and self-reported stress ratings were collected. Two weeks later participants’ memory for this task was examined. It is known that greater Cortisol reactivity was associated with enhanced memory, most prominently in children.
