Theory of mind is a child's ability to understand the mental states of not only himself but also others, generally it takes preschoolers time to develop this , but once they do they are able to perform a variety of functions and see outside their own perspectives. In the study, conducted by Slaughter, Peterson and Moore examined the relationship between theory of mind (ToM) and the persuasive abilities of young children, ages 3 to 8. The researchers hypothesized that there would be a positive correlation between the relationship between theory of mind and persuasive skills and conducted what they called the peer persuasion task to determine children's ability to persuade a peer such as a puppet named Matty to make him eat a piece of raw broccoli and brush his teeth (Slaughter, Peterson, & Moore, 2013) . In this task the experimenters used the puppet who claimed that eating broccoli and brushing his teeth, because of the toothpaste, was disgusting and refused to do so. The experimenters then encouraged the children to do their best to generate a persuasive argument after each refusal, of which the puppet refused three times for each task before finally committing to the act. This process allowed children who had not given up or were running out of ideas the opportunity to continue generating more persuasive arguments. With the tasks, the experimenters also used motivation versus altruistic variables to see if it changed the way the child tried to persuade the puppet. The child was told that he would get a sticker if he made the puppet complete the task (motivation) or (altruism) that Matty would get a sticker once he completed the task (Slaughter et al., 2013). The researchers decided to score the children based on how they persuaded the puppet, who were classified into 4 groups and scored in 3 ways: simple injunction or question, stuffing it in its mouth or commanding, which
