Corsi's block tapping task

From Psy3242

Purpose

The Corsi's block tapping test examines for working (short term) memory capacity by asking subjects to remember and repeat a series of numbers. This test is a spatial version of the digit span tests because the participant must repeat a sequence of taps on a set of blocks that is presented to them.

The digit span test and reverse digit span test is conducted with the Corsi's block tapping test so that the scores of all the tests can be compared to see if there were any correlation or significant differences between the scores. The test simply asks for the participants to verbally repeat a sequence of numbers either forward or backwards.

Instructions

Digit Span

1. The tester will say a list of 3 numbers and ask the participant to repeat them back. 2. Continue to add a number to the list each time until an error is made. 3. Make sure the tester records the numbers down so they do not forget the list.

Reverse Digit Span

1. The tester will say a list of 3 numbers and ask the participant to repeat them BACKWARDS. 2. Continue to add numbers to the list until all an error is made.

Corsi's task

1. The tester starts by presenting a sequence of 4 taps and asking the participant to observe and repeat the sequence. 2. The blocks should be positioned so that only the tester can see the numbers.

Additional Instructions

After completing all three tasks, compare the scores of the tasks. Do they correlate? Are there significant differences in the tasks?
