The autonomy treatment and SCL increase individual and team productivity when intrinsic motivation is included as a control.

With both intrinsic motivation and closeness as controls, SCL increases individual but not group productivity while the treatment only affects group productivity. Standard errors in parentheses. **p < 0.01, *p < 0.05 one-tailed t-tests.
