Description:
This task assesses working memory and requires the participant to sequence
different visually and orally presented stimuli. Pictures of different foods
and animals are displayed with both a sound clip and written text that
name the item. The task has two different conditions: 1-List and 2-List. In
the 1-List condition, participants are required to order a series of objects
(either food or animals) in size order. In the 2-List condition, participants
are presented both food and animals and are asked to report the food in
size order, followed by the animals in size order.
Children ages 3 to 6 are given 4 practice items in each condition: a 2-stimulus
item in which both images appear simultaneously, a 3-stimulus
“simultaneous” item, a 2-stimulus item in which the images briefly flash on
the screen one at a time, and a 3-stimulus “flashing” item. Participants
ages 7-85 receive 2 practice items in each condition: a 2-stimulus
“flashing” item and a 3-stimulus “flashing” item. All of the actual test items
are presented in a “flashing” manner.

Ages 3-6:
For the youngest age group, each practice item has multiple questions.

trials the child answered correctly. The final choice on the examiner
screen is #4, and indicates the conditions for which the test will be
discontinued and no more items will be presented.
