Description
|
This project investigates the role of biological and physiological variables in third-party punishment (3PP) and cooperation. It focuses on sexual dimorphism and traits like 2D:4D ratios, facial dimorphism, and fluctuating asymmetry, examining their relationship to cooperative behavior in men and women using the Prisoner’s Dilemma game.
The dataset includes data from 839 participants (511 women, 328 men) who played a two-stage experimental game. Measurements include digit ratios, facial dimorphism, self-perceived attractiveness (SPA), and fluctuating asymmetry. Data on punishment and cooperation decisions were also collected and analyzed.

Notes
| All participants were Caucasian university students, with standardized conditions for facial photographs and hand-scans. Data from other ethnicities were excluded to avoid confounding variables when computin facial features.
Participants played a two-stage game including the Prisoner’s Dilemma (PDG) and third-party punishment (3PP). Biological data were obtained through hand-scans and standardized facial photographs.
Facial features were computed using TPS software and MorphoJ software. |
