Material Reflectiveness Setting

[hliS658H]

I have two questions on this ceiling material in the model

1.  The material is very reflective, but when I open it in the material browser, I can't see where I can change the reflective setting. 

2. I remember the image size shown in wall scene under " Appearance"  can be adjusted bigger, but can't remember how to do it now

There is nothing in that screenshot that would add reflectivity except Finish, but that's showing Flat/Matte.  Is there something less than Flat/Matte? 

Post a screenshot showing what you are seeing that you think is reflection.  

FWIW:
