Open defecation is practiced by more than one billion people throughout the world and leads to significant public health issues including infectious disease transmission and stunted growth in children.

To support CLTS and the attainment of open defecation free communities, chiefs were considered key agents of change and were empowered to drive CLTS and improve sanitation for their chiefdom.

In experiment 1, 152 ovariectomized nulliparous (n=77; no reproductive experience) and primiparous (n=74; having had and raised one litter of pups) Wistar rats were trained on an ambiguous t-maze task and tested for memory system bias.
