Pedersen and colleagues (2007) used path analyses to determine whether measures such as disruptive behavior at ages 6 and 7 are related to how lonely children feel when they are 12 and 13 years old. An advantage of this type of analysis is that
A) the causes of loneliness can be isolated and measured.
B) the path to loneliness can be traced back to experiences at an earlier age.
C) participants are not affected by the researcher's expectations.
D) random assignment eliminates observer bias.
B) the path to loneliness can be traced back to experiences at an earlier age. Because Pedersen et al. (2007) measured children at different points in time, she could use earlier measures to predict later ones.
