Instructions In this experiment, you will
complete a simple visual search task. A series of
forty trials will be given. For each trial, you
will first be told which letter you are to search
for (the target letter). Then a large block of
letters will be shown. Your job is to search
through the block of letters as quickly as
possible and find the target letter. Once you
have found the target letter, write down the
letter to its immediate right. You will have five
seconds to do this. If you are unable to find the
target within the five seconds, put a dash in the
appropriate blank on your answer sheet. If you
have any questions, ask the instructor now. If
not, click on the arrow key to begin.
