Step 1 of 2Read the paper
Do young children overvalue things just because they have them? Researchers in Brazil let 141 kindergarten children play with their own toy and a similar borrowed toy, then asked whether they would trade. They also checked whether keeping the toy was linked to teacher-rated mood, gender, handedness and finger-length ratio.
How to read it
- Read the first paragraph of the Introduction to pin down what the endowment effect means.
- In Materials and Methods, note the three trade questions and the order in which they were asked.
- The first paragraph of Results holds the key percentages; skip the equations if they feel heavy.
- Ask yourself what a control group could have added to this design.
