Step 2: Acquire the Target Orientation
Once your head is aligned with your body (i.e. when the halo is
bright green), a set of parallel bars will appear at the end of the
tunnel, representing the target orientation.

Memorise the target orientation.
Note: Your hand must remain in the neutral position on your lap
throughout the target presentation. Please do not align your hand
to the target orientation during target presentation or during the
memory delay period.

Step 5: Check Response
In some of the trials a line of balls will be projected from your
hand towards the targets, allowing you to verify whether or not
you correctly aligned your hand. On other trials you will see
only a single spherical projectile without any indication as to
whether your hand was correctly aligned to the memorised
target orientation.
A green sphere appears briefly if the task sequence is
completed correctly, regardless of the accuracy of the hand's
alignment to the target.
