Perhaps you should try some spelling variations:
"symbolischer interaktions" » "symbolischer interaktion", "symbolische interaktion", "symbolischen interaktion"
"symbolic interactionism" » "symbiotic interactions", "symbolischer interaktionismus"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("symbolic interactionism") OR ("symbolischer interaktions"))) OR ("symbolic integration")).
• Removing quotes may allow a broader search: (((( symbolic interactionism ) or ( symbolischer interaktions ))) or ( symbolic integration )).
• Adding a wildcard symbol may retrieve word variants: (((("symbolic interactionism") or ("symbolischer interaktions"))) or ("symbolic integration"))*.
