Friends' influence on adolescents' academic achievement motivation: An experimental study.
Abstract
To examine the influence of friends on adolescents' motivation to achieve in school, each of 118 eight graders was paired with a close friend. The pairs of friends were randomly assigned to either an experimental or a control condition. In the experimental condition, the friends discussed dilemmas that required them to decide between 2 actions reflecting different levels of achievement motivation. In the control condition, friends discussed topics unrelated to school. Before and after the discussions, all adolescents made decisions on the dilemmas independently. The 1st hypothesis was that discussions of the dilemmas would lead to an increase in the similarity of friends' decisions. The 2nd hypothesis was that the discussions would lead to shifts toward more extreme decisions

“School effort is an overt, observable behavior, making it a visible group norm (Thibaut & Kelley, 1959), susceptible to reinforcement patterns within interaction dyads (e.g., Sage & Kindermann, 1999), and a likely area of agreement among friends (Berndt et al., 1990).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
