Perhaps you should try some spelling variations:
"cognitive effects reports" » "cognitive aspects reports", "cognitive effects report", "cognitive effects repousse", "cognitive effects remote"
"cognitive defect reports" » "cognitive defects reports", "cognitive deficit reports", "cognitive effect reports", "cognitive defect report", "cognitive direct reports", "cognitive select reports"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"cognitive effects reports\") OR (\"cognitive defect reports\"))".
• Removing quotes may allow a broader search: (( cognitive effects reports ) OR ( cognitive defect reports )).
• Adding a wildcard symbol may retrieve word variants: (("cognitive effects reports") OR ("cognitive defect reports"))*.
