DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

[0069] A. Overview

[0070] To assist in a better understanding of the invention, a preferred embodiment will now be described in detail. It is to be understood that this preferred embodiment is but one form the invention can take and is not exclusive of the forms that are possible.

[0071] The drawing figures will be referred to throughout this description. Reference numerals and/or letters will be used to indicate certain parts or locations in the drawings. The same reference numerals will be used to indicate the same parts or locations throughout the drawings unless otherwise indicated.

[0072] B. General Environment of the Preferred Embodiment

[0073] The example given by this preferred embodiment is particularly relevant to the teaching of young children (kindergarten or first graders) and/or children with hearing loss (either total or partial), or children with other types of perception impairments, such as learning disabilities. It is therefore to be understood that the concepts discussed would be by analogy applicable to any learning training, regardless of age, capabilities, or impairments; and particularly to learning of rule-based systems such as speech, reading, language (English and others), math, and the like.

[0074] As will be described in more detail below, the preferred embodiment entails a computer-based interactive system. In the above described environment with regard to learning by relatively small children, a teacher or speech/hearing professional is generally involved to initialize and monitor the training. However, the invention certainly can be used at home by non-technically trained persons.

[0075] Still further it is to be understood that the specific example discussed has some subtle concepts which are generally well known to those in this art, although some will be brought out here to assist those relatively unskilled in the art. First, the learning training discussed is many times very fundamental and highly repetitive. For example, a deaf child trying to distinguish between the sound of a one syllable word and environmental noise such as a car horn or a dog bark, must start at a very fundamental level. The student would be given intensive repetitive tests where the stimuli were simple one syllable words compared to non-speech sounds. Through long period, repetitive training, the child will begin to distinguish the same. This will lay the foundation for movement to more difficult differentiations; for example multi-syllable words or sentences compared to multi-syllable words or sentences of different makeup. One of the main advantages of the present invention is to allow such sometimes tedious, intensive work to be marshalled autonomously by the computer system while maintaining a level of motivation and interest in the user. This allows the teacher, professional, or parent the ability to ration their attention, while maintaining the interest of the user, and in fact, providing the user with the level of difficulty needed for the user's particular needs.

[0076] The following description will be broken down into these segments. First, a basic discussion of a preferred hardware system will be set forth. Thereafter, a high level description of the software of the preferred embodiment will be given. This will be followed by a specific discussion of various fundamental concepts utilized in the system. Thereafter a specific example of operation of the system will be set forth with reference to various examples of data and stimuli that are useful for these purposes. Finally, a discussion of options, alternatives, and features of the invention will be given.

[0077] C. Hardware

[0078] FIG. 1 diagrammatically depicts a basic hardware setup according to the preferred embodiment of the invention. What will be called collectively system 10 includes a computer processor 12 which is preferably an IBM or IBM compatible 386 microprocessor with four megabyte RAM and an 80-100 megabyte hard drive capacity. System 10 can work with a minimum of a 286 microprocessor with 640 K-RAM and 60 meg hard drive. For institutional use a 386 DX/25+, 8 mega byte RAM, 100-200 megabyte hard disk is recommended.

[0079] An EGA-VGA adapter and monitor 14 are preferred as the visual display component of the multi-perceptual system 10 . Monitor 14 comprises a part of what will be called the user interface to system 10 which includes not only monitor 14 for presentation of visual stimuli and information readout, but also a user input that can consist of either a touch screen 16 (Edmark Corporation Touch Window) available from a variety of vendors; a mouse 18 , such as is well known in the art; or a keyboard 20 . In the preferred embodiment all three components can be used to facilitate not only user input but also operation of the programming and entry of data.

[0080] A sound stimuli component for the user interface consists of a speaker 22 (in the preferred embodiment a bookcase size speaker) that is interfaced to processor 12 by a Covox sound board available from Covox, Inc. 675 Conger Street, Eugene, Oreg. 97402 (see reference numeral 24 ). Optional components related to auditory stimuli can include standard head phones 26 placeable on user 28 ; or a cochlear input selector 30 which is attachable to a cochlear implant in a user; or a vibrotactile device 32 which is connectable to a vibratory transducer that could be used by a user. A microphone 36 can also be included.

[0081] As is known to those skilled in the art, each of those auditory components could be used for presenting sound to a user. Speaker 22 and headphones 26 would present sound as is normally understood; whereas the cochlear implant and vibrotactile devices would present it in a electrical or vibrational mode to those who are deaf or have a hearing impairment.

[0082] FIG. 1 also shows security key disk 34 (from Dallas semiconductor), such as is well known in the art, is useful in limiting access to system 10 . System 10 will not operate unless the key disk 34 is inserted, for example, in the parallel port on processor 12 . Furthermore, it can contain initialization information regarding the user which can facilitate easy start up and use of system 10 . An alternative is to require users to utilize a pass word which is keyed in on keyboard 20 .

[0083] It is further noted that in the preferred embodiment, a comprehensive manual would be given to the user of system 10 to assist installation of the programming, hookup of the hardware, and initialization and use for a variety of users and purposes.

[0084] D. Software Configuration

[0085] FIG. 2 depicts diagrammatically the high level structure of software according to the preferred embodiment of the present invention, and its use of memory.

[0086] The software runs on MS-DOS and is written in Turbo C and C+ language.

[0087] A floppy disk is supplied with the programming and is installed into computer 12 as is conventional and within the skill of those of ordinary skill in the art. For example, floppy would be inserted into drive A, the enter key pressed, and INSTALL typed in and again the enter key pressed. Approximately 4 megabytes of space are needed in RAM and 60-80 meg on the fixed drive for the program and at least 15 files must be set up. If a printer is utilized it should be connected to the LPT1 port. By following the instructions on the screen, completion of installation of the programming can be accomplished. After these basics are installed, audio, picture, and stimuli library and supporting executables are installed in a similar manner.

[0088] What is called the core stimuli for the programming are approximately 1600 words, sounds, pictures, and the like which form the basis for the training lessons presented with system 10 . These core stimuli have been carefully selected on the basis of years of research and study, but system 10 allows the addition of customized stimuli. For example, it is known that personalized information allows better and quicker learning. Thus, picture stimuli that have a personal connection to any learner, (including small children) can be added to the core stimuli according to known in the art methods. Likewise words, sounds, and other stimuli can be added in.

[0089] As will be discussed in more detail later, different courses can be offered with system 10 . In this preferred embodiment, a course on listening will be described. Different courses on listening, or courses dealing with pre-reading and reading subject matter can be separately installed and utilized. As previously mentioned, courses on mathematics, geography, and the like could also be prepared.

[0090] As will be further described below, memory also contains a plurality of different lessons for each specific course to allow variety for the user as well as varying levels of difficulty. In the preferred embodiment approximately 1000 lessons are utilized.

[0091] E. Software Overview

[0092] By referring to FIGS. 2 and 3 A- 3 D a high level diagram of the construction and interrelationship of the software according to the preferred embodiment is shown. As previously explained, various courses would be possible. In this embodiment course 1 dealing with listening is specifically discussed.

[0093] Under each course is a plurality of lesson packages. Each lesson package (in the preferred embodiment approximately 160 lesson packages) would involve between 1 to 15 lessons. System 10 has about 1,000 lessons available to it.

[0094] For the listening course each lesson would generally contain one or more word lists. In this context word lists can mean words, combinations of words, sentences, non-speech sounds, or any auditory stimuli.

[0095] As shown at FIG. 2 , the lessons can also consist of feedback, libraries, mode, and tasks.

[0096] Therefore, when operating system 10 , a user, teacher, parent, or professional, can select from a number of different lesson packages related to the specific learning training desired for the user. As can be appreciated, the content of the lessons can cover wide variation of subject matter.

[0097] FIG. 2 specifically sets forth what is involved with each possible component of a lesson.

[0098] First of all, tasks consist of one or more of pretest, posttest, practice, training, and production. Specific examples of these will be given later. Basically the lesson can predetermine whether the user is prepared for the level of difficulty of the lesson using a pretest. It can also posttest the student to better check what has been learned. A practice component can allow the user to familiarize him or herself with the particular task. The term training refers to the actual learning process.

[0099] A production task involves a variety of tests or processes aimed at requiring the user to essentially produce a result. The production task may differ substantially from the training and is incorporated as an optional feature to go along with the listening training. One example is to have the student vocalize a word or try to match the word as sounded by system 10 .

[0100] The term “Mode” in the preferred embodiment means selection between essentially a discrimination task or an identification task. A discrimination task merely asks the user to state whether two presented stimuli are the same or different. Identification tasks present a stimuli and then ask which of two or four succeeding stimuli matches the original stimuli. A comprehension mode is also possible which presents the stimuli and then requires language comprehension to select the answer.

[0101] The “libraries” portion of each lesson relates to the specific audio visual presentations that will be available in the lesson. As can be shown, audio, pictorial, and text are either taken from pre-stored core stimuli, or as indicated by the box labeled “input from stimuli editor”, can be customized and input for use. Still further, the edit feature allows editing of the existing core stimuli.

[0102] As is also shown in FIG. 2 , textual stimuli are coded into the libraries so that essentially the difficulty of their presentation can be quantified in valuing the difficulty of certain lessons. This will be discussed further below.

[0103] The feedback component of the lessons simply is any number of built-in presentations that provide reinforcing feedback and motivation to the user of system 10 . For example, a child could be rewarded periodically with a puzzle, stars, or a painting task. Older children or adults could be rewarded with something at perhaps a higher level such as a text message.

[0104] FIG. 2 also shows that an important aspect of the software is the “strategy” for the tasks and for the lesson packages of the course. In the lower right hand corner of FIG. 2 , it is shown that either by customized selection, or by default settings programmed into the software, such things as ordered or random presentation of stimuli for each lesson can occur, certain performance criteria can be adjusted for each user, the level of abstraction of stimuli can be adjusted, rate of progression, and the amount of audio visual support for each task can be selected.

[0105] The strategy therefore can essentially set the initial difficulty of each lesson and then the rate of progression as far as difficulty from then on.

[0106] In the preferred embodiment, as shown in FIG. 2 , software allows recordation and analysis of the entire response profile of the user for each lesson or lesson package. As will be described in more detail later, the reporting not only simply records right or wrong answers, but also codes each answer with a value correlated to the meaning of the learning strategy of the user. It also records reaction time and other criteria, other than simply the right or wrong answer. From this reporting is derived a performance profile which is compared to the performance criteria and imposed strategy. System 10 can then either autonomously (or ask the teacher or professional to) evaluate the performance and select a change in strategy (either more difficult or less difficult) or remain the same. Additionally, as the tasks are proceeding, system 10 autonomously and dynamically can change the difficulty of the tasks based on performance. The change is not necessarily isolated to the stimuli presented, but rather can vary across such subtle matters as changing the amount of time for each task, changing the level of acceptable success or failure rates, providing less or more supplemental information with which to contemplate an answer, or allowing more repetitions of certain tasks.

[0107] It is to be understood that the system is very flexible in this aspect but provides the advantage of dynamically, on the fly, monitoring a user's progress and then adjusting one or more of these sometimes subtle criteria to in turn adjust presentation of the tasks and allow the user to not only go at his/her own speed, but to discover and explore and to find his/her own best learning strategies.

[0108] FIG. 4A shows the basic flow of the program, including initialization and how the computer sets up tasks. FIG. 3A shows the basic method of “DO TASK” from FIG. 4A . FIG. 4C shows how performance is quantified to raise or lower next lesson difficulty; while FIG. 4D does this for next task.

[0109] F. Training Task Displays

[0110] FIGS. 4 A- 4 C provide examples of the type of display that would appear on the user's screen during a training task. In FIG. 4 A, the basic template for a screen display task is shown. It is important to understand that in the preferred embodiment, these templates are uniform for all tasks. The left-most column are called “top level” spaces. This is where the stimuli being compared by the user is identified. The boxes to the right of “top level” are called “attributes” and as will be further seen below, basically are features, characteristics, or sub-parts of the top level stimuli. It is important to understand that the attributes may or may not be available for review by the user in certain testing levels. If the testing is more difficult, attributes which would allow one to explore and discover more about a stimuli may not be available to make the task more difficult.

[0111] As is also indicated at FIG. 4 A, the lesson name would be displayed along with the name of the current user. The trial counter segment could be a linear bar having various segments which would represent to the user the number of trials before any successful completion of a task.

[0112] Therefore, top level presentations relate to a whole stimulus, whereas the attribute sections are a presentation of a whole stimulus or abstractions of the whole stimulus. FIGS. 4B and 4C give concrete examples. For discrimination tasks FIG. 4B shows that in a touch screen situation the first top level stimulus would be presented. The user would then review the bottom top level stimulus when presented and consider whether they are the same (“S”) or different (“D”). If the user believes he/she knows the answer, the S or D would be. Depending on the level of difficulty of the particular lesson, an attribute (in this case the abstraction consisting of the relative length of the word of the top level stimulus is displayed). “Boat” has a very short, black bar. “Watch the elephant” has a relatively longer black bar. This helps the user in their discrimination between stimuli.

[0113] FIG. 4C shows an identification task. To the right of the question mark would be presented the top level stimuli. To the right of “1” and “2” would be presented the options for matching with the “?” stimulus. Again, attributes could be displayed to assist in the task. The user could be exposed to only attributes at either stimulus or response levels, and/or only whole stimuli at the other level, in order to force synthesis of the parts or analysis of the whole.

[0114] It is to be understood that the software allows the user to replay either the top level stimuli to encourage exploration of auditory information. The user is never penalized for requesting repetitions prior to selecting an answer. The user can also replay the attribute information and explore the variety of receptional information available before making a selection.

[0115] G. Word Lists

[0116] FIG. 5 shows an example of a word list. The word list would be used for either comparing in discrimination tasks between the opposite words, or using them in identification tasks. In FIG. 5 , each left hand column word is a one syllable mixed frequency word. Each right hand column word is a three syllable mixed frequency word. This word list would therefore be available for use by lessons which would contrast one versus three syllable words with similar frequency characteristics.

[0117] As can be appreciated, a wide variety of word lists are possible. At the end of this description are provided a number of examples of different types of word lists.

[0118] H. Different Attributes

[0119] FIGS. 6A and 6B illustrate the different types of attributes available for certain top level stimuli. In FIG. 6A the top attribute is a non-speech attribute which indicates that the top level auditory stimuli in this instance is a frog croak and not a word. Such an attribute again would help the user in identifying and memorizing frog croak as a non-speech sound.

[0120] The second display indicates relative length of the phrase by use of a black bar. The third display shows as an attribute the syllables and each word of the phrase. The fourth display shows each syllable and the stress one would place when speaking each syllable.

[0121] FIG. 6B from top to the bottom shows what are called segmented attributes. For example, the words are included in separate boxes and a picture is associated with the descriptive word “elephant”. Alternatively the different words are in separate boxes with syllables represented by bars that can be called up by the user to explore and investigate before answering. Thus can be seen there are even clues that can be programmed in for investigation by the user.

[0122] FIGS. 7 and 8 A through 8 F specifically shows AV levels for discrimination tasks. Those for identification tasks are similar.

[0123] I. Strategy

[0124] FIG. 9 provides a screen display for the various strategy types that can be selected by teacher or professional, or which can be built into default settings in the software. The user's progression or regression through a series of tasks and lessons is determined by his/her own performance and how that interacts with the general strategy selected for that user initially. As can be seen in FIG. 9 , the strategy types are comprised of four elements namely (1) initial presentation (can be either “B” in which “both” stimulus and responses are displayed or “T” in which “target-only” initial presentations are displayed); (2) audio/visual set (either “A” which is auditory level only or “V” which includes visual and auditory levels); (3) type of word group (either same word group or different word group); and (4) rate of progression/regression (fast, medium, or slow).

[0125] J. Preview

[0126] FIG. 10 simply shows a screen-display whereby samples of stimuli to be included in the following training tasks are shown to the user. Full auditory/visual support is provided and the user can request as many repetitions as desired. It is exploratory only and not task related.

[0127] K. Production Training

[0128] FIG. 11 illustrates a production training task as indicated in FIG. 3 . It includes three components: Listening, recording, and judging. The user can listen to a prerecorded stimulus just as if he/she were in the perception training tasks. Only one stimulus however serves as the model for production. The user can record and play back the stimulus and contrast it with the model prerecorded stimulus. The clinician or user can make a perceptual judgment about each of the user's productions by selecting one of five stars following each production. To advance to the next trial the clinician can select either “next” or “O.K.”. Next represents an unacceptable production and “O.K.” an acceptable production. Stars are shown for “O.K.” and “balloons” for “next”. The trial counter corresponds to the number of trials set and the user defaults. Stars will appear for “O.K.” response.

[0129] The production training simply allows the user to practice vocalization of words or sounds, in this case, and to allow a teacher to evaluate such vocalizations.

[0130] L. Feedback

[0131] As previously mentioned, FIGS. 12A and 12B show two specific types of what are basically rewards that can be programmed into the software. In the preferred embodiment the feedback options are tied into the success performance of the user in the task. For each successful or correct answer on the first try, the user would receive some sort of an indication in the trial counter box at the bottom of the screen. Then periodically the feedback display would appear. Based on the number of stars in the trial counter box, the puzzle feedback of FIG. 12A for example would break up a picture into the number of puzzle pieces which correspond to the number of stars received by the user. The user can then try to complete the puzzle using the number of pieces he/she has achieved. The number of pieces may or may not be selected to correspond to the number of first try correct answers, however. Such a puzzle is intended to try to provide motivation to the user to get as many first time correct answers as possible.

[0132] In FIG. 12B, a similar feedback is provided. The user is allowed to use different colors to paint the picture. The amount of time the user can spend painting and how frequently this occurs can be specified in each users file.

[0133] M. Initial Selection Options

[0134] FIGS. 13 - 19 show screen displays according to the preferred embodiment of the present invention which relate to initial selections for a user related to what level and strategy of tasking is indicated for the user. In FIG. 13 , for example, the teacher or professional is presented with a series of YES or NO questions related to the indicted level of speech perception for the particular user. Depending on these answers, the teacher or professional is directed to other selection screens.

[0135] For example, regarding pattern perception, if the user is a very young child with a hearing deficiency, he/she may not be able to differentiate between speech and non-speech. If so, lessons and tasks within the lessons would have to start at a very basic level. If the child could differentiate accordingly, he/she may be able to start at a slightly higher level of lessons and tasks.

[0136] FIGS. 14 A- 14 D show similar type questionnaires which further break down the questions regarding pattern, word, syllable, and perception; again further trying to identify the potential beginning level of tasks for the user.

[0137] FIG. 15 merely asks which task mode (discrimination or identification) is desired.

[0138] FIG. 16 requests selection of strategy for moving through lessons. The strategy is made by selecting one choice from each of the categories. For example, TVSMED would be “Target only” on initial presentation, “Visual O.K.” if user can not perform the auditory only information, “Same group” for the tasks, and “MEDium rate” of progression.

[0139] FIG. 17 shows the selection of the level for AV support, as previously described regarding FIG. 7 .

[0140] FIG. 18 then asks which of the specific tasks between pretest, preview, training tasks, production tasks, and posttest tasks are desired.

[0141] Finally, FIG. 19 allows default settings to be made for each user relating to feedback, tasks, and libraries for AV settings.

[0142] It can therefore be seen that a wide variety of flexibility is given to both customize or individualize training for each individual, as well as present different learning strategies for each individual.

[0143] N. Operation

[0144] The basic components and concepts of system 10 have been provided above. An example of an operation of system 10 will now be set forth.

[0145] By referring to FIGS. 2, 3 , and 20 A- 20 L, initiation and preparation for operation of system 10 can be seen. Initially a user file must be created for each person using system 10 . The operator would access the editor in the software by selecting EDITOR from a menu manager (see FIG. 20A ). A series of editor menus will appear ( FIG. 20B ) Key F4 should be selected to add a user. As shown in FIG. 20 C, one could copy the user profile for an existing user or by so indicating create a new user profile.

[0146] Certain basic information is then entered including user name ( FIG. 20D in the preferred embodiment up to eight characters long). Thereafter ( FIG. 20E ) certain information is then requested. In this Fig., feedback defaults are shown. These can be changed by moving the cursor to those values pressing back space and entering new values or by pressing a space bar to toggle between available settings.

[0147] Next the user default screen should be configured (see FIG. 20F ). The entries to the questions presented in the user default screen can be answered based on a previously described options that are available for each user. When completed, this user default screen will be preserved for each of the lessons that are built for that user.

[0148] Thereafter, a lesson plan is created (see FIG. 20G ). This lesson screen can be completed either by (1) selecting existing lesson packages by pressing F5, (2) selecting existing lessons from the lesson library by pressing F2, or by (3) entering new lesson components for task mode, word list, attribute, strategy and starting AV level. Thus up to 15 lessons can be selected and can be either selected by default or customization. As shown in FIG. 20 H, if answered YES, the screen of FIG. 20 I, for example, would appear which would produce default settings specific to the user and not the existing lesson defaults.

[0149] FIG. 20J shows an example of how one would customize a word list.

[0150] FIG. 20K shows how one would select a strategy. Again, strategy defines a rate of advancement and direction of movement through specified lessons.

[0151] Finally, FIG. 20 L, an attribute set can be brought up on the screen and selected for a specific lesson. Only one attribute type per lesson can be chosen.

[0152] Other selections would then be made available for customization or default selection:

[0153] Starting A/V level: This option specifies the A/V level setting for displaying the stimulus during the training task.

[0154] Preview: This YES/NO option controls whether the user is given a preview of the stimuli prior to the training task. This, option may be used to insure the stimuli are in the user's vocabulary before entering the task.

[0155] Training: This YES/NO option controls whether the user engages in the perception training tasks.

[0156] Task Pass Percent: Determines the percent correct needed to pass to next training task. Default value is 75%.

[0157] Pretest: This YES/NO option controls whether users are given a pretest before receiving training. Pretest value can be compared with training values and posttest values to document changes.

[0158] Posttest: This YES/NO option controls whether the users are given the posttest on completion of training for a lesson.

[0159] Reserve Testing Group: This YES/NO option is relevant only if the pretesting and/or posttest option is set to YES and controls whether content used during testing is or is not used during training.

[0160] Pretest Judgment: This YES/NO option is relevant only if pretest is selected. It controls whether a score obtained on pretest is used to place the user in a training series. The next two options “advance criteria” and “enter criteria” are used to set values for entering a training series based on the pretest score.

[0161] Advance Percentage: This option is relevant only if pretest is selected. The value entered determines when a user advances to the next lesson level. For example, if the value were set to 85% and the user obtained that score or better, the user would advance to the next lesson level for pretest rather than enter the training series.

[0162] Enter Percent: Relevant only if pretest is set to YES. The value entered sets the lowest acceptable limit for entering a lesson series. If the user can not obtain this entry score he/she will be moved back to a less difficult lesson level.

[0163] Production: A five choice option controls whether the user will be placed in a production task and if so when the production task will be sequenced in the training. Options include “none”, “pretest”, “posttest”, “pre/posttest”, and “group based”. If “group based” is selected the production task would be given each time the user moves into a new contrast group.

[0164] Production A/V Level: This option specifies the A/V level setting for displaying the stimulus during the production task.

[0165] Method of Grouping Contrasts From Word Lists: This option controls the way in which groups or stimuli are chosen and contrasts are paired in a lesson. There are four ways of grouping and presentation. A contrast ALWAYS involves a stimulus item from each set. Stimuli within a set are never contrasted. The four choices illustrated below are preceded by an explanation of the terms used.

[0166] Training Contrasts: This option specifies a number of contrasts to be presented within a training task.

[0167] Reps/Training Contrasts: Option specifies a number of times each contrast is repeated within a training task. The total number of trials presented per task can be determine by multiplying the number of training contrasts with the repetitions per contrast. The total number within a task can not exceed twenty.

[0168] Enter the number at the cursor. The backspace or delete keys can be used to erase the current value.

[0169] (Trials=): The number of total trials will appear after training contrasts and repetitions per training contrast have been specified. This value is dynamically derived by multiplying the two contrasts and repetitions. To change this value, one or both of the two preceding parameters must be changed.

[0170] Test Contrasts: This option specifies the number of contrasts to be presented within a pretest and/or posttest task.

[0171] Enter the number at the cursor. The backspace or delete keys can be used to erase the current value.

[0172] Reps/Test Contrast: This option specifies the number of times each contrast is repeated within a pretest and/or posttest task. The total number of trials presented per task can be determined by multiplying the number of training contrasts with the repetitions per contrast.

[0173] The total number of trials within a task cannot exceed 20.

[0174] Enter the number at the cursor. The backspace or delete keys can be used to erase the current value.

[0175] Trials=): The number of total trials will appear after test contracts and repetitions per test contrast have been specified. This value is dynamically derived by multiplying the contrasts and repetitions.

[0176] Enter the number at the cursor. The backspace and delete keys can be used to erase the current value.

[0177] Number of Screen Choices: This option specifies the number of answers available during a task. Either a two-choice or four-choice option is available.

[0178] Select either “2” or “4” by pressing the space bar.

[0179] Retries per trial: This option specifies the number of retries or chances the user has to select the correct answer before moving to the next contrast.

[0180] Enter the number at the cursor. The backspace or delete keys can be used to erase the current value.

[0181] Use Text: This option specifies whether text will be displayed during the task.

[0182] Select “Yes” or “No” by pressing the space bar.

[0183] Site Group: This optional feature specifies the library number of a special library established for specific site purposes.

[0184] Enter the number at this cursor. The backspace or delete keys can be used to erase the current value.

[0185] Picture Group: This option specifies which picture libraries should be used to display visual information. The choices are “Standard” “SEE 2”, and “Oral”. “Standard” refers to illustrated pictures. “SEE2” refers to Signing Exact English sign language and “Oral” refers to presentation of mouth postures. Only one picture group can be chosen per lesson.

[0186] Select the choice by pressing the space bar.

[0187] Audio Group: Standard English is the only audio group currently available.

[0188] Audio Overlay Name: This option allows background noise to be integrated into the audio signal. The default option is to leave the choice blank and have no overlay signal.
