Dynamic Kids: A Look at Dynamic Screen Learning in Children Labeled Moderately-Severely Mentally Handicapped. Presenters: Vicki K. Clarke, M.S. CCC-SLP and Stephanie Williams, M.S. CCC-SLP Closing the Gap, 23rd Annual Conference Saturday, October 22, 2005 12:30-1:30 Relevant Characteristics of Children’ with Moderate-Severe Mental Handicaps: Problems and Solutions Attention Span and Focus Difficulties: Definition: Decreased ability to attend to relevant environmental stimuli for sufficient periods to be successful. Difficulty filtering out irrelevant information to the task at hand. Decreased focus on relevant input. Problem: Child is distracted by the operational buttons on the deviceSolution: Hide the programming/modify buttons if possible. (Full screen Mode onDynavox Series 4 devices) Solution: Eliminate external switches as possible.Solution: Set a delay on the activation of the programming buttons so that the childhas to hold the button down for an extended period of time. Most children won’t wait out the response and will ignore the button since it doesn’t produce a response. Problem: Child has difficulty filtering out irrelevant information (ex: clicking noises ondevices, extra “dead space” in recordings of digitized devices) on the device. Solution: Change output of button activation- no “click” or add “click” or “enhancedclick” to help child focus on successful activation Problem: Child has difficulty attending to/locating specific symbols on a page withmultiple symbols. Solution: Color-coding symbols by parts of speech and in syntactically correct order(Goosens & Crain, Engineering Dynamic Display and Joan Bruno, Gateway to Language & Learning programming). This helps to decrease the number of items in the visual scan. The child learns to predict what color symbol and only has to scan items in that color grouping. Having the buttons ordered syntactically “leads” the child from left to right across his device making it easier to predict from which color group his next word is included in. Solution: Consistent placement of symbols on a page so that the child learns toanticipate the placement of a targeted symbol even before a page loads. Set the search engine to alphabetical sort so that the placement of symbols doesn’t change as the frequency counts continuously adjust. Solution: Gray out background symbols when a popup loads.Solution: Consider maintaining a symbol set with which the child is already familiarfrom past AAC use. If a child has only been exposed to Picture Communication Symbols, use these symbols primarily on his device. As vocabulary and comprehension increases, add in other symbols as desired. (something old, something new) Problem: Child has difficulty retaining a message intention while pairing words acrosspages on dynamic screen device. Solution: Target either word pairing (sentence building) OR navigation goals mutuallyexclusively at first. If concentrating on word pairing then decrease the navigation demands by adding key words from different parts of speech to pages. For example, on the food page, include a few relevant verbs (eat, drink) and descriptive words (gross, hot/cold) so that the child can sentence build without the added challenge of navigation. If concentrating on navigation, accept single button activation without requiring word pairing. Solution: Make sure that you use a consistent page organization to decrease thecognitive load of communication. Pages that are organized in a consistent manner promote efficient (automatic) access to vocabulary. Solution: Provide quick and efficient access to frequently used vocabulary. This canbe achieved by replicating certain vocabulary items on multiple pages or single hit access to important messages. Sensory Integration Issues: Definition: An maladaptive reaction to sensory information perceived through vision, hearing, touch, taste or smell Tactile Input Problem : Child avoids activating buttons because of the pressure requiredSolution : Select a device that is very sensitive to touch such as a dynamic displaytouch window. Problem : Child exhibits excessive force when activating buttons on device (not usuallytruly sensory in nature) Solution: May be caused by the child not recognizing the function of the device forcommunication and using the device for pressure input to hands. Increase functionality of symbols to increase desire for accuracy. Provide child with alternative means of receiving pressure sensation to hands. See OT regarding a “sensory diet.” Solution: May be caused by child’s motoric system “overshooting” the target (ataxicmovement). Consult with PT/OT, consider offering shoulder/elbow support to increase stability and control of arm/hand movements Solution: Explore alternative methods for accessing the device (joystick, mouse, etc.).Problem: Child seeks sensory input from manipulating a variety of media such ascrinkling/tearing paper or ripping Velcro symbols off pages (can be a PECS learned behaviors instead of truly sensory) Solution: No paper overlays or increase the thickness of paper to decreasecrinkling/tearing value (lamination) Auditory Input Problem: Excessive non-communicative activation of voice output to hear ancillarysounds of device (clicking, Velcro release, tapping, recorded “dead space,” hearing the same message repeated) Solution: Adjust the button hold down and release times on the device. If a child is ina compulsive repetitive movement of tapping the symbol, interrupting the rate of activation can stop the stimulation received from the repetitive movement/sound. Solution: Change the Behavior of a button. For example, turn off “speak on entry” onDynavox Series 4 devices) until the message window is activated (breaks the behavior patterns as noted above); remove the “click” output; set Message Window Settings to “clear after speaking” so the child won’t perseverate on pressing a message window that contains numerous previously activated messages. Problem: Child is sensitive to the loudness of the device OR requires the device to bevery loud (can be fluctuating). Solution: Use the Change Volume behavior on a button. This would allow you to preseta “loud” and “soft” volume on the device for individual messages. This requires no action on the part of the user. Solution: Place a button for volume adjustment on one of the main pages of a user’spage set so that the volume can be easily adjusted by the user or a partner depending on the circumstances and the child’s ability to handle auditory input at a given time. Visual Input: Problem: Child enjoys switching screens on dynamic display devices but not alwaysfunctionally. Solution: Allow the user unstructured exploration time to familiarize themselves withvocabulary locations. Solution: Partner assisted linking to help the child stay on appropriate pages. This isonly used if the nonfunctional linking is detrimental to the child’s participation and learning. Solution: Increase the interest level and functional outcome of use of the symbols toencourage child to stay focused and on task. because there are tangible rewards for not switching pages. Solution: Turning animation on or off depending on visual need. Animation can beused to direct the student’s attention to a key concept being taught. Solution: For scanners, you can deselect “scannable” in the Modify button menu fornavigation buttons. This allows only the communication partner to have access to navigation buttons via touch. This should be used cautiously so that users don’t miss out on the independence of accessing their own pages. Learned Helplessness: Definition: A psychological state of being when a person no longer attempts to affect his fate given a history of failure and pessimistic view his own ability to change his situation. This theory is part of the Attribution Therapy that looks at how our belief of the causes of our successes and/or failuresdetermines our response. People with learned helplessness believe that their successes and failures are determined by external uncontrollable factors which leads them to exhibit withdrawal,unwillingness to approach new tasks and a lack of persistence (pessimism). Problem: A child looks to a familiar partner to more efficiently relate information forhim- a “Human VOCA.” Solution: Have the communication partner develop amnesia- purposeful ignorance.Partner can ask questions to guide the child in the direction of the answer/information. Solution: Involve the AAC user to the fullest extent possible when completing avocabulary gathering task for page creation. This can be integrated into everyday educational and therapy activities. When looking for words and messages to include on a communication page, allow the AAC user to choose words or symbols that will be placed on their page. For example, if making a page for “places to go” present all options (ex. symbol finder on device, books, magazines, picture cards, etc.) and allow the individual to choose the items that are most relevant to them. This give ownership and a sense of control. Problem: The child exhibits passive aggressive behaviors such as feigned ignorance andrefusal to participate. This often looks like the child doesn’t understand what he is supposed to do because there are no outward obvious refusals, simply a lack of action, often accompanied with a decidedly pleasant demeanor (“He’s so cute!”). Solution: HIGH levels of expectation for communication. Speak to the child as youwould any other child his age and WAIT for a response. If no response comes (after at least 15 seconds), begin going through the Prompt Hierarchy until some response occurs. ALWAYS expect a response. NEVER assume ignorance. Solution: Increase the likelihood of successful, errorless communication by setting upsingle hit conversations/interactions. Solution: Increase the positive social rewards of successful communication by settingup easy motivating communication activities where errors are ignored and successes are enthusiastically responded to with natural consequences. Solution: Improve the availability of motivating specific vocabulary so the child canhave extremely positive interactions. Set up errorless joke pages and new pages. Solution: Set the child up in a leadership role in his environment (school, classroom)where she is able to lead others using her communication device (ex: leading the school pledge, giving the class the steps to complete a recipe or other class project) Solution: Team up with the child to accomplish any task at which he hesitates, “Let’sdo this together.” Try to avoid offering to “help” the poor little fellow- this only further increases the feelings of helplessness. Once you are both successful in accomplishing even a part of the goal celebrate yourselves! “We ROCK!” Always respond enthusiastically to any individual accomplishment, “You’re the QUEEN!” Enthusiasm is your best weapon in these scenarios. Solution: Offer to do the activity for the child while she watches. No demands. Manyof these children are very stressed and scared of new activities/demands. Watching you work helps ease their fears. Most children will step in and try fairly quickly. Be on the lookout for indications that she is ready to try even a little of what you’re doing. Ask the child for help in any small part of the activity (turning a page, getting something for you). Allow her to refuse. WAIT! No child likes to be bored when the opportunity is ripe to try something interesting. She simply has to overcome her fear. Be aware that this fear has very real physical symptoms: increased heart rate, sweating, shivering, tunnel-vision and nausea. Solution: Physical contact, touching a shoulder, letting the child hold your hand whileyou press buttons, turn pages, touch the touch window etcetera. This makes the action belong to both of you, thereby decreasing the child’s perception of sole responsibility if it goes badly. Recognize that even choice-making for toys, leisure and food items can be scary if the child has NEVER had these opportunities. It’s best described in the literature, by one author with autism, as an overwhelming, debilitating fear of baring ones soul. Behavioral Manipulators- Optimists: Definition: This is the optimistic brother of the Learned Helpless. These children have a history of failure that they consider a temporary situation caused by other people and their demands. They will aggressively attempt to manipulate the environment for their success. They will vehemently oppose any direction/instruction. They are persistent when motivated. They have a very strong need to be able to successfully initiate and change topics of conversation independently.Problem: The child proactively avoids tasks including any instruction using hiscommunication device. Solution: Teach the child task completion with visual symbols available. Offersimple, easily accomplished tasks that have definitive beginnings and endings. Use visual schedules, “finished” boxes, “first…then” explanations, and activities with a certain number of items that have to be dealt with before the task is complete. Maintain a POSITIVE attitude. Take yourself OUT of the equation. Use a timer or other visual cue that the task is over. The therapist/teacher and child are a team following the cue of the timer/activity/picture schedule. Use intermittent reinforcement of hard/boring activities followed by highly motivating activities. Solution: Visual schedules, moveable popup for choices and on-screen motivationcharts can be used on the dynamic screen device. This serves two purposes: the child has the visual reminders of the task at hand and the child has successful use of hisdevice. The more successful interactions with the device, the more motivated the child is to use the device for other purposes ( communication!).Solution: Entice the child with activities/partners/environments that you know arehighly interesting and motivating to them. Many professionals respond to this idea by saying “He needs to learn to do his work.” “This is life! He needs to learn tocooperate!” “He isn’t going to always get his way.” Etcetera, etcetera, etcetera. WRONG, WRONG, WRONG! He needs to have internal motivation to accomplishtasks and communicate. Our job is to help him develop that desire. Once a positiverelationship is established with the child, he will work to maintain that relationship and therefore do the tasks you are asking simply to make you happy. Once he is successful enough in doing teacher-directed activities he will be less reluctant to try them on his own even if you are not around to cheer him on (internal motivation!). NEVER get in a battle of wills with these children in which you are the “bad guy.” Have externalfactors control the situation as much as possible- timers, visual schedules and inescapable (comfortable) locations for working. Work to maintain the positive relationship at all times!Enthusiastically reward ALL cooperation! Problem: The child has a history of failure using his communication device so he resortsto less advanced forms of communication (the “Human Voca”) or behaviors.Solution: Make the device MORE successful than the other forms of communication.Replace behaviors with communication by putting easily accessible symbols on themain page of the device to allow the child to escape a situation such as “I need a break.” or “I need to leave.” Give the child a way to come back with easily accessible symbols on the main page such as “I’m ready!” After a small break, ask them if they are ready to return modeling the use of the “I’m ready!” button. Professionals are often concerned that if they offer a break the child won’t ever choose to return. Usually this isn’t the case. There is significant stress in not being able to escape an unpleasant situation that can be significantly reduced if the child has control over the amount of exposure he has (think claustrophobia). The stress for this child is no different than forthe child with Learned Helplessness with the same physical symptoms. This child is just more vocal and physical about avoiding the sensations. Problem: The child walks away from activities; has her own agenda and won’tparticipate. Solution: Tempt the child with favored activities. Change the order of activities todraw her back into the setting. Offer tantalizing choices and enthusiastically welcome her back. Try VERY hard not to physically move her back into the situation. The natural response to being pushed is to push back. The natural response to being pulled is to pull back. Consider where children learn to control things with their bodies! (modeling, perhaps?). Encourage her verbally and through gestures to come back (pleasantly, please); smile and WAIT. Don’t even make a move toward her because her natural response will be to move away. Only interfere if they are going to hurt themselves or others or, destroy property. Try to manipulate the environment so that they never escape in the first place including making the activity so interesting that they don’t want to escape. If you have to physically help the child, subtly move behind her and gently encourage her to come help you out. Explain the upcoming order of events (ex: “first…then…”). Show her the picture schedule of events so she cananticipate the end of the activity. Decrease demands when she returns and ease her back into the activity. Solution: Consider why the child is walking away. Is the child sick, having stomachpains (especially in our autistic children!), too stressed, BORED, afraid of failure?? Problem solve and accommodate. Solution: Back off. At times everyone needs a break. Just as the Learned Helplesscommunicator needs to be able to ask for a break, the Behavioral Manipulator needs to have an “I need a break button” on her main page as well. Set this up in the same fashion described for the Learned Helpless child. Decreased Partner Expectations for Typical Communication: Definition: Due to a history of communicative failure, the child’s partners do not expect effective, novel and/or intelligent responses from the child. Communication patterns include asking only yes/no questions, leading questions (in which they already know the answer) and imperatives (directives- as in “show me the…”). Problem: The child does not initiate communication.Solution: It has been well documented in the literature that the communicationpartner often dominates interactions with individuals with significant communication disabilities. Social scripting is a strategy that can be used to encourage interactive communication. Scripts teach individuals to move beyond basic needs to communication for purely conversational purposes. Social scripts assist with learning to initiate and maintain turns in conversation. For more information on social scripting visit www.aacintervention.com and www.Lburkhart.com. Problem: The child is not motivated to participate in social conversation given the limitedresponse he has access to on his communication system. Solution: A “random” speaking feature on some devices allows multiple vocabularyitems to be assigned to one button. When the button is selected, device will choose one of the items at random and speak it. Selecting the button again will cause the device to choose and speak a different item. This feature is beneficial for individuals who have a limited number of buttons per page but want a variety of rich and communicative messages. It could also be beneficial for scanners because it would reduce the number of vocabulary items to scan through. Solution: Buttons can be programmed to sequence through a series ofanticipated comments so the child can participate in errorless conversations with single activations. Solution: Use of a dictionary feature on some dynamic display devices allows the userindependent access to the majority of the vocabulary available on the device. This allows the child to successfully communicate using a rich vocabulary to describe experiences that have not been anticipated by his partner. (Ex: Daddy cut down a tree with a chain saw and hit the car!). Solution: Help the child select photographs, both personal and ones accessedprofessionally, to enrich his story-telling and increase motivation. Some dynamic display devices afford the ability to import pictures onto buttons and backgrounds of pages. Photograph backgrounds can also be used in light-tech displays to add interest for the user. Decreased Receptive/Expressive Language Skills Definition: A delay in a child’s basic language comprehension and use including his augmented language caused by lack of exposure, natural modeling and effective teaching. The child has limited experience organizing their thoughts, manipulating word order and morphology (meaningful word endings such as “-ed”) and then understanding the navigation and functional operations of their communication device. The techniques used to introduce communication symbols may be a key factor in identifying why some augmented communicators become very successful symbolic communicators while others are very poor symbolic communicators. The actual process of introducing symbols becomes more important when working with individuals who have language disorders in addition to the inability to speak (Carlson, 1997). Problem: During evaluation, the child shows limited skills in spontaneous use of thecommunication system to request, respond and comment. Solution: Give the child long-term exposure to the system with very specific goals andmodeling of augmented communication in very functional, highly motivating activities.Solution: Assess the child’s understanding and use of in-context symboliccommunication VERY carefully. Look carefully at the kind of symbol he appears to readily understand (photographs, picture symbols, words..). Consider the functions he’s already communicating (even behaviorally) such as requesting action, commenting, responding. Determine what vocabulary he appears to understand both symbolically and verbally such as nouns, verbs and adjectives. Once you have a firm understanding of where the child is “today,” target vocabulary for functional, independent communication AT THAT LEVEL. Set goals for the child’s “today” based on these initial findings. Target and model vocabulary and language functionsone step higher for the child’s “tomorrow” (Beukelman and Mirenda, 1992). For example, if the child appears to readily understand using single words to request, target expansion of the number of single words he understands for functional, independent communication right now. Model and scaffold attempts to communicate using 2 word phrases and functions such as commenting and conversational interchanges. Solution: Teach the child a very limited number of communications potentiallytargeting only one piece of vocabulary at a time with modeling for all others initially.This piece of vocabulary should be HIGHLY motivating. Modeling just one step above this level should be used for all other vocabulary so the child can be “immersed” in augmented language. As the child becomes successful at the first communication, gradually add in more expectations. Once the child integrates the concept of successful communication using his new system, new vocabulary can be added more quickly and in combination. Continuously monitor the child’s understanding to provide additional vocabulary so he does not get bored. Problem: The child does not spontaneously use his device functionally, preferring toresort to less sophisticated forms of communication using gestures and partner-assisted scanning (20-questions). Solution: The child may not understand enough rich vocabulary to effectively “tell astory.” Provide access to new words and encourage the exploration and use new words. Access to words can be provided through to use “dictionary pages”. Dictionary pages can be arranged categorically and alphabetically. The dictionary pages should be used as a reference set for accessing more vocabulary. Many professionals may find that these pages are a good place for young children to explore new vocabulary. For more experienced AAC users, words that may not be on their immediate communication pages can be accessed through the dictionary pages. Problem: Although the child understands language at a sentence/conversational level, heexpresses himself in only single word utterances. Solution: Provide opportunity for highly structured word pairing. Use the AACsystem to provide access to written communication activities. Many AAC systems provide symbol prediction, word processing, and printing. Allow the child to use their spoken language to create written language. This slows down the expected rate of communication as the child is creating language for a partner to see later. Writing allows the child to put create, edit and revise their work without time pressure. Problem: The child appears to understand language at a single word level only.Solution: Promote language learning by providing access to single word vocabularies.A critical consideration in choosing how to display symbols on an AAC display is the potential of the design to promote language learning. The flexibility by which single words and symbols can be combined encourages the AAC user to generate novel language. All AAC users, regardless of chronological or developmental age characteristics, will benefit from a communication system or display that allows for novel language generation. Problem: Child does not appear to spontaneously comprehend picture symbols.Solution: Use digital images for individuals who require a concrete representation ofobjects and activities than a standard symbol set (ex. DynaSyms or PCS) can provide. Dynamic display devices, In particular preprogrammed vocabulary sets, allow us to model and teach language for the child’s future. The non-speaking child’s partners are able to model, scaffold and prompt; all the techniques traditionally used in speech/language therapy. The assumption is not made that the child, given a voice, is going to know how to use it (see Cafeiro, 1998). Aided Language Stimulation is an exceptional tool in teaching augmented communication users ( Goosens, C. Crain, S., and Elder, P.
