“…It is important to note, however, that within this notable surge in research studies uncovering the positive implications of prosociality, there is a disproportionately greater focus directed toward infancy (Brownell, ; Dunfield, Kuhlmeier, O'Connell, & Kelley, ), toddlerhood (Hay & Cook, ; Svetlova, Nichols, & Brownell, ), and early childhood (Eisenberg, Spinrad, & Knafo‐Noam, ; Knafo & Plomin, ; Romano, Tremblay, Boulerice, & Swisher, ), with far fewer studies bringing a developmental perspective to the issues of defining and measuring prosocial behavior during adolescence. This is despite evidence suggesting the frequency and nature of prosocial behaviors may change during this age period as a result of (1) cognitive and affective development (e.g., developing a greater capacity for abstract thinking, role taking, affective labeling, moral reasoning); (2) changes in interpersonal relations (e.g., simultaneous increase in frequency of face‐to‐face contact and digital communication with peers and decrease in time spent with family); and (3) changes in social context (e.g., increase in school population size coinciding with a more departmentalized and impersonal environment, disruption to social regularities and a necessary social role restructuring; Goldstein, Boxer, & Rudolph, ; Shifflet‐Chila, Harold, Fitton, & Ahmedani, ; Steinberg, ). Therefore, with the continuing development of social cognition and emotional regulation, changes in familial, relational and educational processes, as well as an actual relocation from the typically more intimate elementary school context to a more impersonal, larger‐scale secondary school, it is important to expand the study of prosocial behavior with a greater focus on adolescence.…”
