What's the code to echo out a specific extra field?

I want to create different template structures for different categories besides having a list beneath the post that lists the extra fields.

Heres the code now thats echoing the extra field but I want to say echo a certain field.

echo $this->item->extra_fields[1]->name;

I was looking for this, thanks. :-)
