1) What is the purpose of this study?
2) What does this study add to the literature?
(i.e. What do they investigate that hasn’t been looked at before?)
3) What, do the researchers note, is an important feature of the procedure?
1) How many participants were there, and what were their ages?
2) Describe the apparatus.
3) Describe the experience of a participant during testing.
1) There were three different types of trials. According to the findings, which type of trial led to more sharing? Was this true in both age groups?
2) Report the percentage of 18-month-olds and 25-month-olds who shared more often than would be expected, due to chance, with the vocal adult.
1) What difference in sharing behaviors was found at the age of two?
2) What development around the age of 2 is likely tied to the observed findings in this age group?
1) How do these results compare to findings with nonhuman apes?
2) In their conclusion, the authors speculate as to when in “ontogeny” , (i.e. the development of humans throughout their lifetime), it is adaptive to share at one’s own cost, and even with unrelated individuals. What do they suggest as the reasons we develop such pro-social behaviors?
