Perhaps you should try some spelling variations:
decreased response » increased response (Expand search), increases response (Expand search), decreased responsiveness (Expand search)
decrease with » decreases with (Expand search), increase with (Expand search), decrease in (Expand search)
of decreased » of deceased (Expand search), of decrease (Expand search), not decreased (Expand search)
decrease not » decrease akt (Expand search), decrease at (Expand search), decrease on (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
with objects » with projects (Expand search), art objects (Expand search)
decrease of » decrease in (Expand search)

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: (( decrease of decreased response decrease ) OR ( decrease NOT decrease with objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease of decreased response decrease ) OR ( decrease not decrease with objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of decreased response decrease ) OR ( decrease not decrease with objects ))*.
