This study on clock time can show you how the cognition of clock time developed in 6-, 8-, 10-, year-olds, and focused on three problems: (1)how the children transfer the digital clock time and the analogous clock time.(2)how the children tranform the clock time in reallife story. (3)what difference between the normal chidren and the ADHD children's clock face drawing?
The the main results are as the following:
(1) Although with different speed, the proformance of transfer and the transformation of clock time in chidren increased with age. The transfer task is easier than the transfomation task.
(2) Time-telling is easier than time production in the transfer task in 6-10 years-old children. It's easier to transfer the clock time under the clockwise transfer task than the anticlockwise one.
(3) There is boundary effect when children transform clock time, and the type of task effeted the children's proformance.but no distance effect appeared.
(4) Different strategies are used in 6-10 year-old children.6-and 8-year-old children draw clockwisely and 10-year-old children use anchoring stimulous to help drawing in clock face drawing task.counting and computation strategies are common in transfer task and computation strategy is the main strategy in transformation task.
(5) Normal children scored higher than ADHD children in the number spacing in clock face drawing task.there is no difference between the cognition of time in free-drawn clock and the examiner clock procedure in 8-year-old normal and ADHD children
