Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Individuals tended to become more prosocial over time when the classroom descriptive norm for prosocial behavior was initially high, and a similar mechanism was found for aggressive behavior. → Krijnen 2024 q2 i? High density and low centrality benefit individual citizenship: aggressive boys became less accepted over time in high-density or low-centrality classrooms. → Krijnen 2024 (2)

q2 · i? · review · r3

The review reports, citing Ahn and Rodkin (2014), that "in high-density or low-centrality classrooms, they became less accepted over time," suggesting social cohesion shapes peaceful behavior; Zwaan et al. (2013) found well-included boys in high-centrality classrooms showed less aggression.

"In low-density or high-centrality classrooms, aggressive boys were more accepted, whereas in high-density or low-centrality classrooms, they became less accepted over time (Ahn & Rodkin, 2014)."
