Because people are reading this excerpt from the article without reading the paper itself, this isn't a self-survey. The survey itself is a 'manipulation'. (But I won't comment on the reproducability or value of this methodology) > This left us with a final sample of 84 dyads, randomly assigned to either the Scarcity (n=42) or Control (n=42) conditions. Dyads across conditions did not differ in age, child or caregiver sex, caregiver education, or family income > The caregiver and child were seated across from one another at a table. The child completed an unrelated experiment with the researcher, while the caregiver completed the Scarcity or Control manipulation survey on a tablet. When the caregiver had finished, the researcher left the room under the guise of loading a second survey onto the iPad, leaving the caregiver and child alone with a toy the experimenter happened to offer as she left. A video camera and/or tape recorder recorded their interactions. And there was also a second experiment: > The second experiment used [..] tiny “talk pedometer” devices worn by children that record their conversations and count the words they hear and say. > [..] analyses revealed that parents engaged in fewer conversational turns with their children at the month’s end, a time that typically coincides with money being tight
