Perhaps you should try some spelling variations:
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
fear processing » pear processing (Expand search), fur processing (Expand search), after processing (Expand search)
faster decrease » rate decrease (Expand search)
decreased fear » decreased heart (Expand search), decreased mean (Expand search), decreased after (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)

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

• Removing quotes may allow a broader search: (( decrease AND decreased fear processing ) OR ( decrease at decrease faster decrease ))~.
