The coin that is most current is flattery? Stability and discontinuity of false praise-telling from 5 to 7 years of life.

Abstract Preschool children engage in flattery behaviors, including expressing opinions toward other people or objects that—although favorable—are not truly held. Research shows that in the following years, the number and complexity of motives underlying such insincere behavior increase. The current study focused on children’s overt behavior, examining two aspects of the development of false praise-telling: individual stability and group-level discontinuity. Using an art-rating task, a total of 164 children aged 5 to 7 years were tested at three points in time (T1/2/3): MT1 age = 5.66 years, SD = 0.1; MT2 age = 6.65 years, SD = 0.16; MT3 age = 7.61 years, SD = 0.14. The results show that, having become capable of giving false praise in politeness settings at 5.5 years of age, children continue to flatter others in this way at later ages, indicating that false praise-telling is an individually stable characteristic. In addition, a statistically significant increase in the proportion of false praise-telling to non-lying behavior in children over the 2-year study period was observed. This indicates that the discontinuity, namely the growth in children’s flattery behavior, occurs from 5 to 7 years of age. The findings are discussed with respect to the diverse factors that might underlie and affect children’s tendency to praise others falsely in politeness settings.
