Q

Evaluation 1: (supporting evidence)

A

P- supporting evidence
E- Phineas Gage ( pole through head, suffered from bug personality change) affected the frontal lobe (went from calm to rude/ hot-headed). This suggests frontal lobe affects mood.
E- However, this is a unique case, might not apply to everyone
L- Low population validity bc can’t generalise

A

P- undermining evidence
E- plasticity
E- other area’s ability change function
