words as you can beginning with that letter, but not names of people or places. Are you
ready? You’ve got a minute and the letter is F.” “You’ve got another minute, and this time
the letter is P.”

Ø Say: “I am going to read you a series of sentences. Each sentence has the last word
missing from it. I want you to listen carefully to each sentence, and when I have finished, I
want you to give me a word that completes the sentence as quickly as possible. Do you
understand?” Repeat if necessary

Ø Say: “Now, I am going to read you another set of sentences with the last word missing
just like the ones you have just done. Again, you will need to complete each sentence as
quickly as possible but this time, I want you to give me a word which does NOT fit at the
end of the sentence – this word must be completely unconnected to the sentence in every
way.” Repeat if necessary INCLUDING when a response provided is strongly connected.
Ø If a subject uses the same word in different sentences, say “You’ve already used that
answer, from now on I want a different word each time.” Say ONLY ONCE and score
further repeats as an error.

WORKING MEMORY
Ø Say: “I’m going to say some letters. Pay close attention and listen to what I say. When I
stop, I want you to say them backwards. For example, if I say T-K-R, what would you
say?”
If correct: “That’s right”.
If incorrect: “No you would say R-K-T. I said T-K-R, so to say it backwards you would
say R-K-T. Now try these letters. Remember, you are to say them backwards: X-Q-F.”
Ø Score 1 point if EITHER item within the set is correct.

Appendix 2. FRONTIER Executive Screen Scoring Guide.
FRONTIER EXECUTIVE SCREEN
SCORING GUIDE
The FRONTIER Executive Screen (FES) is a brief executive function screening test that
assesses three cognitive abilities: generativity, inhibitory control and working memory. The total
maximum score is 15, with higher scores indicating better executive functions. Administration of
the FES takes, on average, 5 - 10 minutes and scoring takes < 5 minutes.
These instructions have been designed in order to make the questions and their scoring clear for
the tester. Please read them carefully before giving the test. If possible, leave the scoring until
the end of the session, so the participant will not be able to check whether the tester is ticking for
correct answers or crossing for wrong ones. This might avoid anxiety, which can disturb the
participant’s performance on the test.
To download the FES, as well as updates on publications, please go to the following website:
http://www.neura.edu.au/frontier/research
VERBAL FLUENCY – score 0 to 5
Participant may repeat or perseverate words, for example pay, paid, pays. Record and count
repetitions and perseverations, but only include the first word in the final score. Similarly, score
one correct response when both the singular and plural form of a word is provided, for example
pot, pots.
Intrusions such as words beginning with other letters are recorded but not scored. Proper names
(Peter, Peterborough) do not count.
Use the table provided on the FRONTIER Executive Screen protocol to derive the final score.
INHIBITION – score 0 to 5
Ø On Part B, a response is classified as incorrect (i.e., score = 0) if the word produced is
NOT completely unconnected to the sentence, as required. Such responses include those
which:
o correctly complete the sentence in a sensible fashion;
o are obviously rude, ridiculous or inappropriate such as swear-words or abusive
terms;
o do not fit the sentence but are connected to the meaning of the sentence in some
way;
o are the opposite of the expected response.
Ø If in doubt, err towards leniency.
