Background

This script implements a computerized adaptation of the original Token Test for Aphasia as described in:

DeRenzi, E. & Vignolo, L.A. (1962). The Token Test: A Sensitive Test to detect Receptive disturbances in Aphasiacs, Brain, 85, 665-678.

Duration

5 minutes

Description

Participants are presented rows of rectangles and circles in different colors and are given visual and (by default) verbal* instructions of what to do with these rectangles and circles (Example: "Click on the red rectangle"). The test has 5 phases (10 trials each) that are getting progressively more difficult.

• the verbal instructions are provided with the built-in Inquisit voiceover feature. It can easily be turned off if needed.

Procedure

The test runs 5 phases: each phase is getting progressively more difficult

Phase 1:
a row of large squares (random order of colors: red, purple, blue, green, yellow)
a row of large circles (random order of colors: red, purple, blue, green, yellow)
10 simple instructions such as "Click on the yellow square" - randomized order for each participant
Each task has a predetermined time limit (see Editable Parameters) and can be repeated once

Phase2:
a row of large squares (random order of colors: red, purple, blue, green, yellow)
a row of small squares (random order of colors: red, purple, blue, green, yellow)
a row of large circles (random order of colors: red, purple, blue, green, yellow)
a row of large circles (random order of colors: red, purple, blue, green, yellow)
10 simple instructions such as "Click on the large yellow square" - randomized order for each participant
Each task has a predetermined time limit (see Editable Parameters) and can be repeated once

Phase 3:
a row of large squares (random order of colors: red, purple, blue, green, yellow)
a row of large circles (random order of colors: red, purple, blue, green, yellow)
10 instructions such as "Click on the yellow square and the blue circle" - randomized order for each participant
Each task has a predetermined time limit (see Editable Parameters) and can be repeated once

Phase4:
a row of large squares (random order of colors: red, purple, blue, green, yellow)
a row of small squares (random order of colors: red, purple, blue, green, yellow)
a row of large circles (random order of colors: red, purple, blue, green, yellow)
a row of large circles (random order of colors: red, purple, blue, green, yellow)
10 audio instructions such as "Click on the large yellow square and the small blue circle" - randomized order for each participant
Each task has a predetermined time limit (see Editable Parameters) and can be repeated once

Phase5:
a row of large squares (random order of colors: red, purple, blue, green, yellow)
(empty row)
a row of large circles (random order of colors: red, purple, blue, green, yellow)
(empty row)
10 idiosyncratic audio instructions such as "Drop the yellow circle on the red square"* - order is the same for each participant
Each task has a predetermined time limit (see Editable Parameters) and can be repeated once

• the original DeRenzi & Vignolo (1962) study uses 20 instructions; not all of these 20 instructions can be easily
translated from a 3D-world onto a 2-D computer screen.

Scoring in this script:
Participants get 2 chances per trial.
First Run: if correct 2 points
Second Run: if correct 1 point

Maximum Number of Points: 5 phases x 10 trials x 2 = 100 points

Instructions

see section Editable Instructions.
By default, the instructions are presented visually (but can be easily exchanged with auditory ones).
