2.5.4 Test
Save the experiment, compile, and run to verify that the new additions to the DesignList work as
expected. There should now be 24 trials in random order with non-words occurring twice as
frequently as words.
2.6 Stage 4: Add Block Conditions
Note: This section builds on the experiment created during the previous section. A finished version of Stage3-
LexicalDecision001.es is located in the C:\My Experiments\Tutorials\Using E-Studio Stages directory.
The goal of this stage is to add a block procedure to run the DesignList. This will enable multiple
blocks to be run during the session. In this example, we will run one block of primes with a prime
duration of 500ms and a second block with a prime duration of 100ms. To do this we will add a
List at the block level, declare a new attribute (PrimeDuration) to set the duration of the Prime
display, and move the DesignList to operate in the Block procedure.
2.6.1 Add a block List object
We need to add a block level to the experiment. This will involve adding a BlockList (List object)
and a BlockProc (Procedure object). Click the List object in the Toolbox, and drag a List to the
Structure view as the first event in the SessionProc. Rename the new List object to BlockList.
2.6.1.1 Add a block Procedure
Double click the BlockList in the Structure view to open it in the Workspace. In the Procedure
attribute column, type BlockProc to run the BlockProc from the BlockList. When prompted to
create the BlockProc, answer “yes”.
