Perhaps you should try some spelling variations:
violent processing » fillet processing (Expand search), event processing (Expand search), diet processing (Expand search)
decrease violent » decreases violence (Expand search)
during depressed » during depressive (Expand search), during repressive (Expand search), feeling depressed (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

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

• Removing quotes may allow a broader search: (( decrease _ decrease violent processing ) OR ( decrease to decrease during depressed ))~.
