Abstract

fetched live from OpenAlex

In this paper, we use data from a longitudinal online study to examine how characteristics of prosocial behaviors influence the level of positive affect they produce. Although much work has found that prosocial behaviors benefit those who enact them, the question remains if and how these effects vary based on characteristics of those acts. Using models that adjust for co-occurrence among act characteristics, we find that positive affect produced by prosocial acts is greater for those acts that: involve giving money or items, are seen as unusually kind, elicit positive feedback, and are varied over time. However, we find that the actor's relationship to the beneficiary, reaping benefits from prosocial acts, and the number of successive acts made no difference in terms of resultant positive affect. We conclude with a discussion of potential mechanisms explaining these differing effects and explore practical implications for kindness interventions.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
