CRTT Speed Of Processing (CRTT-SOP) Battery

[McNeil, Pratt, Szuminsky]

CRTT-SOP Task 1 - FINGER TAPPING
Motor Speed
(DIGIT)

Function Tested – Alternate Motion Rate

GOAL:  Data from Task 1 is used to estimate basic motor-related speed across ages, hands, and clinical populations.

The purpose of this task is to provide a nonlinguistic-specific index of fundamental, repetitive, alternate movement speed using a single muscle group (as opposed to AMR measures of speech that use respiratory, velopharyngeal, lingual and labial muscle groups).  Finger taping has been used frequently and meaningfully as a proxy for general movement speed associated with disease and aging.  Because the CRTT requires finger taping speed and control and could influence the final calculation of scores and times measured by the CRTT language processing tasks, this task can be used as a statistical or conceptual covariate for interpreting CRTT test performance.

CRTT-SOP Task 2 - SIMPLE REACTION TIME
Perceptual-Motor Speed
(VISUAL/DIGIT)

Function Tested – Stimulus/Response Rate

GOAL:  This task is intended to measure the time required for detecting and responding to one of thirty different tokens (squares and circles of five colors) with a simple mouse button press. Simple reaction time is frequently classified as a stimulus detection task (Luce, 1986).  However, simple RT is the combination of taping speed and stimulus detection.  As such, this speeded response in this RT task can be separated conceptually (and computationally) from pure stimulus detection (see derived measures below). Task stimuli in the form of written words in the case of the CRTT-R tasks and auditory stimuli in the case of the CRTT-L tasks, as well as the 10 or 20 colored circles and squares on the screen used for response selection and enactment for the prepositional phrases in subtest V through VIII, require responses that are timed. Although speeded responses are not instructed for the CRTT-L or CRTT-R tasks, response times are measured for the CRTT-R-wf and figure into the calculations for scores of 13 (delays), item, command, and overall scores. There is an approximately 100+ msec. cost for this task compared to the inter-tap interval.  This time difference is considered as an estimate of the stimulus detection time (see derived measures below), although it is recognized that although unlikely, response planning and execution requirements could be different from those involved in the AMR taping task.

CRTT-SOP Task 3 - SIMPLE REACTION TIME + FINE MOVEMENT
Perceptual-Motor Speed + Movement
(VISUAL/DIGIT)

Functions Tested – Simple RT + Move. Speed & Accuracy

GOAL:  This task adds the requirement of a simple skilled movement to the previous task.  It is intended to measure movement time plus reaction time.  It evaluates the speed at which participants detected and then motorically move the mouse cursor and click on a token displayed on the screen.  It reflects one of the primary task requirements of the enactment required in the Computerized Revised Token Test. 

CRTT-SOP Task 4 - GO/NOGO
Perceptual-Motor
(VISUAL/DIGIT)

Functions Tested – (Simple RT with Single Stimulus), Goal Maintenance, Response Inhibition

GOAL:  This task is the first of the three choice reaction time tasks that require the participant to cognitively map stimulus items to finger response selections. The primary purpose of this task is to assess (primarily) response inhibition and secondarily, goal maintenance (assessed with hits and misses).  In this task, the participant is set to respond to the next stimulus as quickly as possible; requiring inhibition of response if the “NoGo” stimulus appears.  Since a premium is placed on speed of response, and the perceptual requirements of the stimuli for this task are not demanding (as is required for the CRTT-R-wf-Stroop color-word task) the attentional bottleneck is placed primarily on response inhibition.  Discussed below under “derived” measures, another relevant measure for evaluating the goals of this task, is the subtraction of the correct RTs for Task 4 from the simple RTs from task 2.  This subtraction reflects the costs associated with goal maintenance (remembering and responding only to the target stimulus) and stimulus inhibition.  In addition to the detection of goal maintenance (sustained attention) problems, the number of false positives may also reflect the difficulty suppressing the irrelevant stimulus.

CRTT-SOP Task 5 - SIMPLE STIMULUS/RESPONSE MAPPING
Perceptual-Motor
(VISUAL/DIGIT)

Function Tested – (Choice RT, one Stimulus with two- Choice/One Response), Goal Maintenance, Response Selection and Mapping

GOAL:  This task is the second of the three choice reaction time tasks that require the participant to cognitively map stimulus items to finger response selections.  In this choice reaction time task, like task 4, one token (circle or square) is randomly presented on the screen at a time.  However, unlike task 4, participants are required to respond to each stimulus that is mapped to a specific, predetermined, effector (finger/mouse response button).  While CRTT task demands are minimal for stimulus/response mapping, response selection in general can be a bottleneck in the processing stream and can be impacted by neurological insult.

CRTT-SOP Task 6 - COMPLEX STIMULUS/RESPONSE MAPPING
Perceptual-Motor + Sequential Stimulus/ Response Mapping
(VISUAL/DIGIT)

Function Tested – (Choice RT, Two Stimuli with Two Sequence and Response), Goal Maintenance, Response Selection and Mapping

GOAL: This task provides a measure of conflict resolution through challenges of stimulus/response sequence mapping with both congruent (circle on left and left button response) and incongruent (square on left and right button response) trials.  This task adds complexity to the response mapping demands from those involved in task 5.  Two responses are always required hence no suppression effects (as in Task 4) are directly targeted and evaluated in this task.  Congruency effects can be evaluated by subtracting the RT to correct responses for incongruent trials compared to the correct responses for the congruent trials.  The effects of adding the two stimuli/two response requirements plus the sequencing requirement (overall increased cognitive load) to the single stimulus two-response task can be evaluated by subtracting the RTs for the correct responses in the congruent trials from the RTs for correct trials in Task 5.

Research and Clinical uses

“The Computerized Revised Token Test Battery is a valid and reliable set of language (available in multiple languages), executive function, and non-language speed of processing tasks that capitalize on the reliability of computer administration and scoring, using a sensitive, multidimensional scoring system with millisecond timing of responses.  The test is appropriate for pediatric through geriatric age ranges. Participant/patient performance is reported with individual part-of-speech, item, subtest and overall scores and graphed data.  Normative data are provided for age-appropriate healthy control, aphasic, and deaf (for the American Sign Language battery) populations. The summarized and graphed test performance can be exported to pdf and Excel files for clinical and research purposes.

 

As the test is computer administered and scored, it can be used by individuals from numerous professions for clinical and research purposes.

 

When the test is used in research for descriptive purposes, it is recommended that the 3 or 5 item test is adequate.  When the test is used as a primary dependent measure the 5 or 10 item test is recommended.

    When the test is used for clinical purposes to detect deficits, quantify comprehension severity impairment or as a measure of change, any of the three test lengths provides a valid and reliable metric.”
