SANZEN Neuropsychological Assessment Tests’ Trail Making Test

SANZEN Neuropsychological Assessment Tests’ Trail Making Test (TMT) provides considerable flexibility in the design of a TMT. The user has control over the number of tokens in a test trial, their placement on the screen, the color of each token, each token’s shape (circle, square, or text box), each token’s caption or image, and a subset of tokens can function as “lures.” In addition, custom instructions can be written for each trial; even the few built-in directional messages can either be altered to reflect the language needs of the Participant population or icons can be used in place of the printed messages.

Trials can be specified as either timed (i.e., the trial is terminated after a determined amount of time has elapsed) or untimed. Participants can be prompted, at the test author’s discretion, to respond after a specified time period of not responding. The system provides the user with a running record of test events including all relevant stimulus events, participant responses, and the time (to the nearest millisecond) that the system detected the event. The SANZEN TMT’s summary analysis provides the total time to complete a trail as well as the number of correct and incorrect responses and the number of prompts issued.

As part of an ongoing research program on normal cognitive aging, a substantial number of test results (274) have been obtained using a SANZEN computerized version of the traditional paper and pencil TMT, Part A and Part B. The descriptive statistics, broken out in ten year cohorts for those test results, are provided at the end of this manual in the “normative data” section.

History of the Trail Making Test

The TMT, widely used in neuropsychological assessment (Rabin, Barr, & Burton, 2005), was originally devised in 1938. Originally known as the “Partington’s Pathways Test” or the “Divided Attention Test” (Partington & Leiter, 1949), it was initially part of a battery of tests (Army Individual Test Battery) used to assess “ a variety of intellectual functions different from those measured by the Wechsler-Bellevue Intelligence Scale” (Spreen &

Strauss, 1998). It was subsequently added by Reitan (1979) to the Halstead Battery of

Neuropsychological Tests. While the test is typically administered in its original form, alternative forms have been developed over time to meet the testing needs of either alternative clinical populations or cognitive science research agendas.

An example of an alternate form of the Trail Making Test is the Color Trails Test.

Initially developed as part of a neuropsychological test battery for the World Health

Organization’s cross-cultural study of HIV-1 infection (Maj, et al., 1991), the Color Trails

3

Test was subsequently modified for use with children (Williams et al., 1995). In both cases the modifications are presumed to minimize the cultural bias introduced by the use of Roman letters in part B of the more traditional TMT (Maj, et al., 1991). In addition, the original TMT was frequently duplicated, with such duplication introducing anomalies in the reproduced image and thereby reducing standardization and the ability to directly compare clinical and research findings. The use of color was, in part, designed to discourage this kind of duplication (D’Elia, et al., 1994).

The TMT is thought to provide some assessment of attention, visual scanning, speed of eye-hand coordination and information processing; in addition, Part B also assesses the ability to alternate between stimulus sets and, as such, is a measure of “executive function” (Mitrushina, et al., 1999). Salthouse, et al. (2000), argues that the standard

TMT has flaws that compromise its use as a measurement of executive function and proposes a “variant of a trail-making-type test that is based on the Zahlen Verbindsung

Test, which was introduced by Oswald and Roth (1978) and has been described in

Vernon (1993).” In his view the Connections Test mitigates many of those flaws.

The TMT and its variants require the Participant to link, in the correct order, an array of tokens that are labeled in such a way as to indicate that order. For example, Part A of the standard TMT contains an array of 25 circles containing the numbers 1 - 25. In the paper and pencil version of the test, the Participant draws a line from the circle containing the number 1 to the circle containing the number 2 and then to the circle containing the number 3 and so on until she reaches the circle containing the number

25. If during this process an error is made (e.g., drawing a line to a circle that is not the next one in the sequence), the error is pointed out and corrected, and the Participant then continues to the next correct circle. If the Participant fails to respond for some period of time, she is prompted as to the next correct response and testing continues.

Computer based versions of the TMT function in the same way except that, instead of using a pencil, the Participant uses the computer’s mouse pointer to “click” on (or, with a touch screen, a finger to touch) each token on the screen until she has traversed all of the displayed tokens. All trail-type tests use some form of this basic methodology with alternate forms changing either the number of tokens to be traversed (15 in the

Children’s Color Trails Test ™ , 49 in Salthouse’s Connection Test, and even more if distractor objects in the Comprehensive Trail-Making Test

™ are counted); token characteristics (e.g. color, shape, position and captions); and/or some procedural differences (e.g. timed versus untimed trials, prompt on error, test termination criteria).

Data Management

All SANZEN Neuropsychological Assessment Tests share a single Participant

Database. Whether you are using only one of our tests or all of them, all participant information and test results are stored in a single database file called the “Participant

Database.” This approach greatly facilitates the management of participant information as well as security of the data. To assure the privacy of each participant, access to this database is usercode/password protected.

In order to personalize access to and control over this database, a user must create and set up a Participant Database administrator. Therefore, if a user starts to run a test and generate data before setting up an administrator for the Database, the user will be prompted to read this section of the manual before proceeding further.

Participant Database Set-up

Setting up one’s own administration of the SANZEN Participant Database requires only a few simple steps but, since this process both determines access and insures the security of the database, the process is important and, as such, is highlighted in red below.

PLEASE NOTE: Since all SANZEN tests share the same Participant Database, if you have previously installed any other SANZEN test(s) then setup of the Participant

Database was already done in that previous Sanzen test installation and this step can be skipped.

If, however, this is the first installation of a SANZEN Neuropsychological Test then a unique participant database administrator will need to be set up. The test comes programmed with a single generic database administrator already assigned a preprogrammed USER NAME, USER CODE, and PASSWORD. The pre-programmed

User Name is “Sanzen Administrator,” the User Code is the word “admin,” and the

Password is “sanzen.” For database security, we recommend that the user create a new Database Administrator and then, when that has been successfully accomplished, that the generic, pre-programmed Sanzen Administrator be deleted. The following steps will guide you through this process.

From the test’s WELCOME screen (Figure 1), login to the PARTICIPANT DATA

MANAGEMENT window by clicking the Participant Database button to the right of the screen. This will result in the display of the LOGIN window shown below in Figure 2.

5

Figure 2

In the User Code box type in the word “admin” and in the Password box type the word

“sanzen” (no quotation marks). Both user codes and passwords are case sensitive so be sure to use lower-case. Now press the OK button.

Pressing the OK button will result in the display of the PARTICIPANT DATA

MANAGEMENT window shown in Figure 3, below. (Note: Your system will not be displaying the descriptive information for John Doe.)

Figure 3

6

On the PARTICIPANT DATA MANAGEMENT window click the Administer

Passwords button to open the ADMINISTER USERCODES/PASSWORD window shown in Figure 4.

Figure 4

You are going to create a new administrative. First, click the Add New User button.

Now enter a User Name that can identify this user from others. Then enter a unique login User Code and “Password” for this user. Under the “Access Privileges” box, be sure to give this user Administrator (All) privileges as only users with this level of privilege can get access to this screen to create new or delete existing users. (User privileges will be explained in more detail below). Click the Update button and then

Exit the ADMINISTER USERCODES/PASSWORD window.

Return to the WELCOME screen and click on the Participant Database button. Now attempt to login to the database administration system using the User Code/Password you have just created. This should allow you access to the PARTICIPANT DATA

MANAGEMENT window. From that screen, again click the Administer Passwords

7

button to insure that you can get to the ADMINISTER USERCODE/PASSWORD window using your new code.

Once you have ascertained that your new login information will allow you access to the

ADMINISTER USERCODES/PASSWORD window, it is then safe to delete the preprogrammed Sanzen administrator. In the ADMINISTER

USERCODES/PASSWORD window, select “Sanzen Administrator” from the Select

User pull down list and click the Delete User button to delete the pre-assigned Sanzen

Administrator.

A word of warning : only users with Administrator (All) privileges can create new users, so don’t lose this usercode/password. You can, of course, consistent with your own security policy, create as many Administrator (All) accounts as you wish. See the section on User Privileges below for a discussion of the access rights of the other two levels of security.

User Privileges

From the ADMINISTER USERCODE/PASSWORDS window (accessed, as described above, via the PARTICIPANT DATA MANAGEMENT window) an administrative user can create new users and determine their level of access to the system. A user can be assigned any one of three levels of access.

At the lowest level, Data Entry Only , the user can only enter information for a new participant. They cannot print, edit or even view other participant records. This is a level likely to be assigned to an individual whose only responsibility is to test participants.

At the Data Administrator level, the user can enter new participant information, view and edit all participant records, delete a participant, and print participant records.

Users with Administrator (All) privileges can do all that a Data Administrator can do but can also add new users to the database security system.

Adding New or Editing Existing Participants

From the PARTICIPANT DATA MANAGEMENT window (Figure 3, above), add a new participant by first clicking the Add New Participant button. The Participant Information frame will be cleared and the cursor will be positioned in the first field “First Name.” At a minimum, a first and last name must be entered in order to register a Participant. After

8

entering the relevant information, click the Update button and the new Participant will be added to the Participant Database.

Alternatively, an existing Participant’s information can be displayed and/or edited by selecting a Participant from the pull down list located immediately above the Add New

Participant button. The Participant’s current information and a list of the tests they have taken will be displayed. Of course, all of this can be done only by a user who has “Data

Administrator” or “Administrator” privileges.

Text Output

Participant data cannot be printed directly from the data management system, however, clicking the Output to Text File button (on the PARTICIPANT DATA MANAGEMENT window, Figure 3) allows the user to write to a file’s selected information in formats compatible either with popular word processors, spreadsheets or statistical packages.

Figure 5 (below) shows the window for selecting and formatting the text file.

Figure 5

9

The “Select Participant” box on the left side of the screen automatically and alphabetically lists all participants currently in the system. A scroll bar will appear to the right of this list if there are more participants than can be accommodated in the visible area. Directly beneath this list, the user can choose to send to the text file either the entire list of Participants or only a selected subset by “checking” either All Participants or Only Selected Participants .

If the “ Only Selected Participants ” option is chosen, clicking on the name of each selected participant in the left hand Participant list will cause that name to appear in the

Selected Participants list on the right side of the screen.

Double-clicking on a participant’s name in the Selected Participant list will remove that name from the list.

Once the list of selected participants has been generated then the data items to be included in the list (Participant ID, Name and Address, etc.) can be selected by

“checking” the appropriate boxes.

Finally, the user can specify whether the data is to be formatted in either a “standard” multiline text format suitable for either a text editor or a spreadsheet, or as a single line

(one for each participant selected) comma delimited format suitable for being read by popular “statistical” packages. Clicking the Output to File button will show a standard

“save file” dialog box.

Backup Participant File

It is important that from time-to-time a backup copy of the Participants’ database be made. Loss of data can, at the very least, be frustrating and though today’s computers and disk drives are very reliable, they do still sometimes fail. Clicking the Backup

Participant File produces a “save file dialog” allowing a copy of the Participants

Database to be made. This copy should be made to some external storage device such as an external (usb) disk drive or to a “thumb drive.”

Executing a Trail Making Test

Execute a Trail Making Test by first selecting a test from the “Select a Test” pull down menu at the bottom right of the WELCOME screen (Figure 1). This list will initially display only the SANZEN TMT tests preloaded with the test software, but subsequently will display all tests created by the user as well. The SANZEN TMT comes loaded with

10

the following TMT tests: Standard; Reflected; Standard Flashing; Reflected Flashing;

Reflected and Inverted; Reflected Inverted Flash; Color Trails; and a partial

Connections test presented as an example.

Once a test has been selected it can be initiated by clicking the Execute Trails Test button (at the top of the WELCOME screen), which will open the SELECT PARTICIANT window (Figure 6, shown below).

Select a participant from the pull down list and, if protocol requires it, type in the name of the tester in the text box initially containing “Anonymous.” (As noted in the window, if the participant to be tested has not yet been entered into the Participant Database, it will be necessary to Cancel in order to exit out of this window, return to the WELCOME screen, click the Participant Database button, and enter the participant’s information into the database via the PARTICIPANT DATA MANAGEMENT window).

Figure 6

Clicking the Cancel button will return program control to the WELCOME screen (Figure

1).

11

Clicking the Run Test button will execute the test and the instructions for the first trial will be presented. (Note: The instruction displayed in Figure 7 was written for a test using a touch screen. When a mouse is employed for Participant input the instruction should be amended to substitute “click” for “touch”).

Figure 7

When the Participant clicks on (or touches) the instruction display, it will close and the trail appropriate for the current trial will be displayed. Figure 8, shown below, is a partially completed run of the second or “A” trail (the first is an eight item practice trail) from the “Standard Test” (provided as a preprogramed test with the test package).

When the Participant clicks on the correct token, the border of the selected token becomes a dark black and a green line is drawn from the previously selected correct token to the newly selected correct token. If the Participant incorrectly clicks a token other than the next one in the sequence, a flashing red line will be briefly displayed

12

between the last correct token and new incorrect token; the border of the last correctly chosen token will remain a dark black.

In the example illustrated below, the border of the number 10 token has darkened indicating that it is the last correctly selected token in the trial thus far. The border of this token will remain darkened until the next correct token is selected.

Figure 8

At the conclusion of the last trial a terminating message (or icon) thanking the participant for their participation will be displayed and control will be returned to the

WELCOME screen (Figure 1).

13

TERMINATING A TEST: If the test needs to be terminated prior to its completion the tester can do so by pressing <ctrl>x. This will terminate the test and no data collected during the terminated test will be saved.

Analysis of Results

Clicking the Analyze Trail Making test button on the WELCOME screen (Figure 1) will produce a screen similar to the one shown below (Figure 9).

Figure 9

To see a Participant’s data, select the Participant’s name from the “Select a Participant” pull-down list. A list of all versions of the Trail Making Tests the selected Participant has taken will appear in the “Trail Making Test(s) Taken” box at the bottom right of the

14

screen. Click on the specific test to be analyzed, and the selected test’s data will automatically display.

Clicking the Print button will send a copy of the results to the printer along with the

Participant’s unique identification number (assigned at the time the Participant was entered into the Participant Database), the test version name, the date and time the test was administered, the date and time the report was generated, and the name of the person administering the test (if it was entered).

Checking the “Suppress Participant Identification Information ” box for the Participant(s) selected will suppress all personal identifying information and will include only the nonpersonal identifying information outlined in the paragraph above -- that is, the contents of the text box above the grid (on the left side of the screen) will not appear on the printout. This is useful when printed copies of the data may need to be kept in less secure environments. The linkage between suppressed Participant information and test results can always be recovered by those having at least “Data Administrator” level access to the Participant Database, or by reprinting the analysis with the “Suppress

Participant Identification Information” box unchecked.

Clicking the Export to Clipboard button will place a spreadsheet compatible copy of the summary table on the clipboard.

The grid located on the right side of the panel contains what is essentially a “real time” record of the Participant’s performance for the analyzed test. This record is provided in case the test user wishes to perform an analysis not given by summary statistics. The grid provides information about all of the salient events that occurred during the test.

The first column is simply the event’s i.d. number and reflects its occurrence position in the test. The second column displays the nature of the event. The third column contains an “argument” qualifying the nature of the event. And the fourth column contains a “timestamp” indicating to the nearest millisecond when the system detected the event.

For example, event 1 is Start Trial, an event occurring coincidentally with the display of the trail, and the argument “1” indicates that it is the start of trial 1. This event occurred

609,717,078 milliseconds after the last start time for the computer running the test.

(The computer maintains a running clock indicating the time in milliseconds since it was last started.) Event 2 was a correct response, indicated by the event designation

“Correct;” and the argument “1” indicates the “index” (chronological order) of the token the Participant clicked. If any other token had been clicked, the event designation would have been “Incorrect” and the argument would have contained the index of the token incorrectly selected.

15

The contents of this grid can be printed by clicking the Print button. Alternatively, by clicking the Export button, the grid’s contents can be sent to the clipboard in a format that can be pasted into a spreadsheet.

Creating and Editing a Trail Making Test

Creating or editing a Trail Making Test is initiated by clicking the Create/Edit Trail

Making Test button on the WELCOME screen (Figure 1). This will display the two left vertical panes of the CREATE/EDIT TMT screen seen in Figure 10. Create a new test by clicking the New Test button; edit an already created test by selecting a test from the

Select Test pull down list. Either of these actions will result in the display of the right hand vertical pane seen in Figure 10.

If you are creating a new test, the Test Name and Test Author fields will be blank and must be filled in. There are several options (discussed below) which can be set on this screen (flash frequency, screen color, random color), although you can simply accept the default options.

Figure 10

16

Test Messages : Other than the customizable written instructions (about which more will be said later), this test utilizes only three printed on-screen messages. At the test designer’s prerogative, all three of these messages can be changed in order to accommodate languages other than English (that utilize the Roman alphabet). Another option is to check the “Use Icons” box which will substitute the three printed messages with the three provided icons instead.

Flash Frequency : If the Flash Frequency is set to a value other than “0,” then a randomly selected token’s background color will be temporarily (as defined by the token’s “flash time”) changed to either its “flash color” (more will be said about both flash time and flash color when we get to token defaults and the Token Edit tool) or, if the

“Random Color” box has been checked, to a randomly selected color. (“Flash frequency” specifies how frequently a token will be selected from the pool of available tokens to be flashed; “flash time” specifies how long that flash will last.) If, for example, the Flash Frequency is set to 100 msecs. (i.e. 1/10 of a second), then a token will be randomly selected every 1/10th of a second from the pool of tokens that are not currently showing their flash color. (The maximum allowable value for Flash Frequency is 60,000 or one minute.) While we do not as yet know whether this feature is going to be useful, we do have some preliminary data suggesting that a flashing trail is differentially more difficult for an older population than for a younger one.

Screen Color: Screen Color allows the test author to determine the color of the screen used during testing. Clicking on the white box immediately to the right of Screen Color opens a color selection palette. Selecting a color will add that screen color to the selected test’s parameters and will then subsequently display in the screen color box.

For any selected test, therefore, the color displayed in the screen color box for a selected test will indicate the background screen color that will be presented to the participant when that test is run.

Add/Edit Trials screen

Once the overall test parameters have been defined and saved by clicking the Update

Test button, individual trials can be defined by clicking the Add/Edit Trials button which displays the ADD/EDIT TRIALS screen. When creating a new test, clicking this button produces a screen in which the trail field will be blank. If editing an already existing test, clicking this button produces a screen that looks something like the one displayed in

Figure 11. This is a complex screen requiring some explicit explanation.

The top of the screen displays information about the test and the current trial. Figure 11

(shown below) displays trial 1 from a “Connections” style test. The two boxes at the top

17

right of the screen labeled Left: and Top: display the position of the token currently being edited. This information is useful when attempting to precisely place a token on the screen. Four buttons marked << , < , > , >> allow navigation among the defined trials; clicking them displays the first, previous, next, and last trial, respectively. At certain times these buttons may be inoperable (e.g. when changes have been made to the current trail but not saved).

Down the right hand side of the screen are a series of buttons, checkboxes, and text boxes used in defining a trial. The Create New Trial button establishes the framework for a new trial and provides a clean sheet on which to construct a new trail. ( Note:

When you are first creating a new test you must click the Create New Trial button in order to get started.)

Figure 11

18

Adding Tokens: Tokens are added to a trial by clicking the Add Token button. A new token with its “index” (more about indexes later) as its caption will appear in the upper right corner of the trail area. The token can then be moved to another location by positioning the cursor over the token, depressing and holding down the left mouse button, “dragging” the token to the desired location and releasing the button. If you accidentally click the Add Token button several times without first moving a newly created token, the new tokens will invisibly pile up one on top of the other and can be moved at a later time.

Set Token Defaults: This button opens a small window called the Token Edit tool .

(This tool can also be opened to edit individual tokens by left clicking on a specific token.

Setting a trial’s token defaults through the Set Token Defaults button sets the initial characteristics of all tokens added to a trail after the defaults have been set. These defaults can be kept the same for all tokens within a given trial, or can be changed for any subsequent tokens added within the same trial by again clicking the Set Token

Default and setting new defaults. For instance, setting a green fore color and red back color at the outset of creating a trial will set those as the default colors for all tokens added after those defaults are set unless/until the Set Token Defaults button is clicked again and those default color settings are changed. If midway through designing the trial the default colors were changed, then all subsequently added tokens would reflect the new default settings for color while the tokens added initially would remain on the screen with the initial settings of a green fore color and red back color.

To change the characteristics of individual tokens rather than groups of tokens, left click on a specific token and the Token Edit tool will open next to that token. The token’s index number is displayed in the “cue index” box in the upper left corner of the Token

Edit tool window. For instance, in Figure 11, the Token Edit tool has been opened for token 14, and so the number 14 appears in the “cue index” box to indicate that token 14 is being edited.

The specific options available through the Token Edit tool (whether it has been opened using the Set Token Defaults button or through left clicking to edit a specific token) is discussed below under the Edit Token Edit tool section.

I nstructions : The test creator has two options for creating a new instruction. An instruction file created at an earlier time can be imported using the Load Text From

File capability, or a new instruction can be typed directly into the edit field of the

Instruction Editor . The “load text from file” approach is preferred when the same or a similar instruction is going to be used for a number of different tests, or when the

19

instruction’s text format is particularly complex. If an external text editor is used, it must be capable of saving the file in Richtext (rtf) format.

Figure 13

Timed Trial: Checking the “Timed Trial” box causes a trial to terminate after the time specified in the “Trial Duration” box has elapsed.

Prompt for Response: Checking the “Prompt for Response” box causes the system to cue the Participant for the next correct response by flashing the border of the next correct token for 1.5 seconds. The time between the Participant’s last correct response and the appearance of the prompt is set (in seconds) in the “Prompt Delay” box.

Last Token: Last Token specifies the index of the last token to be used as a valid token in the trail. Any token with an index higher than Last Token can be used as a

“lure” and, if clicked, will result in an error display (flashing red line) as well as an error being recorded in the data record for that participant.

Show/Hide Grid: The Show Grid option allows the test author to display a set of grid lines on the trail space area, facilitating the placing of tokens on that space. Clicking the

Show Grid button will result in the display of the Display Grid Lines box which allows for the specification of the number of horizontal and vertical lines to be used in editing the grid. The grid can subsequently be hidden by clicking the Hide Grid button (aka Show

Grid button).

20

Save Trial: The Save Trial button saves the trial as currently defined to the test definition database. Clicking the Save Trial button saves all of the test author’s changes.

Print: The Print Trial button sends an image of the current trail, as well as some defining characteristics of the trial, to the printer.

EXIT: The EXIT button allows the user to exit from the Add/Edit Trials screen. If changes to a trial have not been saved before the user attempts to exit the current trial

(either using the navigation buttons to move to the next or a previous trial, or to completely exit the Add/Edit Trials screen) a dialog box will open reminding the user to save new changes before exiting. If a user chooses to exit without saving, then changes to the current trial will not be saved.

Token Edit tool

To allow further editing of token characteristics, the Token Edit Tool can be opened inside the Add/Edit Trials screen. Open this tool either by clicking the Set Token

Defaults button (as explained above) on the Add/Edit Trials screen, or by placing the mouse pointer over the token to be edited and clicking the right mouse button. (In

Figure 11 the tool has been opened for token 14, and that number is therefore currently displayed in the Token Edit tool window’s “Cue Index.”)

As previously noted, tokens can be positioned on the screen by simply “dragging” them to the desired position and then “dropping” them. Alternatively they can be precisely positioned using the Token Edit tool. The Top and Left edit boxes allow for precisely locating a token on the trail space. (The area of the trail space is 10,520 units high by

13,360 units wide. Each circle or square token has a width and height of 735 units, while a text token has a width of 1850 and height of 495 units.)

Token Indexes: A token added to a trail is assigned an index, beginning with index 1 for the first token added; each token subsequently added is assigned the next sequentially available index. (Note: this index is independent of token captions). This is important because, when the test runs, the correct trail is determined by token indexes.

Token 1 is the first correct token, token 2 the next correct token and so on through token Last Token . Clicking any token other than the token with the next Cue Index will result in the display of an error indication (a flashing red line). A token’s Cue Index cannot be edited, but any other characteristic of the token can be changed to meet the test author’s need.

21

The Token Type can be selected from among three types of tokens: a circle (such as those displayed in Figure 7); a square (similar in size to the circle); and a text box (an elongated rectangle suitable for displaying text up to approximately ten characters in length).

Token Captions : Token captions can be numbers, letters, or text. The Select Caption

Font pull-down list allows for the selection of any font installed on the computer to be used in the display of a token’s caption. Once a font is selected, choose the “caption” option (beneath the caption box), and then edit a token’s caption by clicking inside the caption edit box. Captions for circular and square tokens can be any combination of keyboard characters up to three characters in length (depending on the font size selected), while text for a text box token can be up to ten characters in length.

Alternatively, rather than displaying a caption, circle and square tokens can contain a small icon (actually a “dingbat” font). Clicking the Icon option will open the icon selection tool shown in Figure 12.

Figure 12

22

Select an icon by first selecting (using the font selection pull-down list in the upper left corner of the tool) a dingbat font containing the icon you wish to use. Each font selected loads a refreshed icon selection. The current example uses Microsoft’s

Webdings © (supplied as part of the Windows ® operating systems). Clicking on an icon displays it in larger view in the lower left corner of the icon selection tool. When satisfied with an icon selection, click the Select button. Clicking Select closes the icon selection window and transfers the icon into the editing tool window. Place the selected icon on the token currently being edited by clicking the Update button. (Note: While there are usually only three or four dingbat fonts initially installed on a system, literally thousands of dingbat fonts (including American Sign Language, playing cards, etc.) are available, frequently for free, on the Internet, any of which can be used by the Trail

Making Test.)

The ForeColor , BackColor and FlashColor determine, respectively, the color in which the caption will be displayed, the color of the token, and, if flashing has been enabled, the color which the token will flash. (See the description of flashing in “Flash

Frequency”). Set any of the colors by left clicking the color box located immediately to the right of the color description label. This will open the color selection palette. Click on a color to select it, then click OK. The color box will be painted with the selected color, as will the token once editing has been completed.

Flash Time sets the amount of time in milliseconds that the flash color will be displayed if flashing has been enabled (by activating the “flash frequency” box on the Add/Edit trials screen, Figure 10) and the token is selected for flashing. Note that every token can have a different flash time and color.

Normative Data

Computerized versions of the TMT have been found in the literature, but the extent to which their measurements correspond to measurements produced by traditional paper and pencil versions of the TMT remains unclear. In developing a computerized test our initial step was to compare performance on a computerized version of the TMT to the paper-pencil version across the lifespan. We have used the “Standard Test,” included as a preprogramed test in your distribution package of the Sanzen Neuropsychological

Assessment Tests implementation of the “Trail Making Test,” in an extended study of normal cognitive changes across the lifespan.

Table 1 shows the means and standard deviations for Participants ( N = 250) between the ages of 5 and 90 on time-to-completion. Participants were recruited from a college student population, relatives of students, or from a local senior center. Participants

23

under 18 years of age received five dollars per hour and participants over 60 years of age received 10 dollars per hour. Participants between the ages of 18 and 59 received extra course credit for their participation. Participants reported no head injuries, neurological diseases, or psychiatric illnesses which they believed would affect their performance. All Participants were given both the standard paper and pencil version of the TMT and our computerized implementation of that standard test as part of a comprehensive package of tests assessing normal cognitive functioning. The order in which the alternative forms of the test were administered was randomly determined for each participant and every attempt was made not to administer both forms of the test on the same day.
