I quoted some remarks by García Lorca about old people in my paper in Bulletin Hispanique, 2011. They may provide a certain frame.

Here are a couple of relatively recent publications that might serve as fodder for thought. If nothing else, they may help in directing you toward sources more relevant to your research question(s):

Thompson, A. E., O'Sullivan, L.,F., Byers, E. S., & Shaughnessy, K. (2014). Young adults' implicit and explicit attitudes towards the sexuality of older adults. Canadian Journal on Aging, 33(3), 259-270.

Lucacel, R., & Baban, A. (2014). Young peoples' perspective regarding aging. Cognitie, Creier, Comportament / Cognition, Brain, Behavior, 18(2), 151-161.

I'm coming from a folkloristic background, where the emphasis has largely been on stereotypes of older women in fairy tales and popular culture:

Schimmelpfennig, Annette.  Chaos Reigns: women as witches in contemporary film and the fairy tales of the brothers Grimm.  Gender Form 44 (Gender and Fairy Tales) (2013).

You might want to have a look at the webpage of Dominic Abrams at the University of Kent: he studies (age) stereotypes (and stereotype threat) among older people.
