Styrene radical stability?

Two different radicals can be produced when an initiator radical adds to styrene- a primary radical and a secondary radical.

 

Would the secondary radical be more stable due to something called hyperconjugation?

 

If so, then why do they http://www.meta-synthesis.com/webbook/14_radical/radical.html show it as a primary one?

The secondary one would be more stable because it would be in conjugation with the aryl ring. Also, secondary cations and radicals are more stable than primary in general
