2.3.3. Task 1C (alternate hand-alternate column turning and
placing test)
Participants used both hands for this test, starting with their
dominant hand for the first column and then proceeding to their
non-dominant hand for the next. Participants picked up disk 1
from the first board and placed it in hole 1 of the second board
using their dominant hand. They left the second disc in place and
moved to the third disc and placed it in hole 3 of the second
board. They then picked up disk 2 from the first board and
turned it over, still using their dominant hand. Disk 2 was then
inserted into hole 2 of the second board. The same was repeated
with disk 4. This pattern was repeated across the board, with
alternating hands for each column. This tested discrete gross
motor abilities.
An error was defined as any time the participant released and
regrasped a peg before getting the peg into its final position, or
any time the participant placed the peg in the wrong location,
released, and then regrasped it in order to correct the placement.
If the participant did both of the above, it was counted as two
errors. Similarly, if the participant released and regrasped a peg
twice, it was counted as two errors. Fig. 1 shows a participant
performing the Minnesota Dexterity Test.
Three levels of difficulty were incorporated for the Mirror Tracer
Test as well. The three tasks were:
