Questionnaires were used to measure affect intensity, positive emotions, confidence, and closeness between father and child, entrepreneur and company, and fMRI scans were used to assess brain activity. The participants were 42 men: 21 entrepreneurs and 21 fathers, aged 24-45. The fathers had no entrepreneurial experience, and founders were growth-oriented and not serial entrepreneurs.
