Talvez deva tentar algumas variações de ortografia:
decrease faster » decrease after (Expandir a busca), decrease further (Expandir a busca), decreased after (Expandir a busca)
fear processing » pear processing (Expandir a busca), fur processing (Expandir a busca), after processing (Expandir a busca)
faster decrease » rate decrease (Expandir a busca)
decreased fear » decreased heart (Expandir a busca), decreased mean (Expandir a busca), decreased after (Expandir a busca)
decrease of » decrease in (Expandir a busca)
of decrease » or decrease (Expandir a busca), not decrease (Expandir a busca), to decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease AND decreased fear processing ) OR ( decrease of decrease faster decrease ))~.
