The first goal: Intentional communication Children all start out as unintentional communicators; that is their behaviors are not intended as communication, but are interpreted by adults as being communicative. For example, crying is interpreted as if the infant were "telling" the parent of a desire for food, even though the crying is involuntary and would have occurred outside of the presence of the parent. Typically, the child next develops into an intentional, but still nonsymbolic, communicator. This is characterized by such actions as reaching, looking at, or pointing towards something to indicate a desire for it. Finally, the child develops symbolic communication skills, the most prevalent being spoken language. (See Normal speech and language development and Assessing intentionality, and the understanding of means-end, causality and symbols.) For a child with disabilities who is not yet an intentional communicator, a communication program should first aim at teaching intentionality. Essentially, this means teaching the child that certain behaviors (i.e. communicative ones) get specific responses, and that, through these, the child can deliberately exert some control over his or her life. At this point the child is pre-symbolic, so pictures and other symbols are not appropriate. Furthermore, it is often recommended that behaviors already in the child’s repertoire be used, rather than teaching new behaviors in addition to new cognitive skills. For example, reaching, looking, pointing, or facial expressions may already be regularly used by the child. The objective, then, would be to assist the child in using them for the purpose of communication (Van Tatenhove, 1987). (See Eye gaze techniques.) General recommendations for teaching a child intentional communication include the following.

The scripted routine A "scripted routine" is a method of teaching a child intentional communication through the use of routines (Beukelman & Mirenda, 1992). Routines present an excellent context in which to teach communication because the child is able to learn the steps that make up the routine. Once the child knows the steps, less cognitive capacity needs to be devoted to the routine, leaving the child more room to focus on other aspects such as communicating about the routine (Yoder & Davies, 1992a; Yoder & Davies, 1992b). The scripted routine involves the following (Beukelman & Mirenda, 1992). Prior to each step in a routine, the adult provides the child with a tactile, olfactory, or movement-based cue that indicates what the next step is. At the same time, the adult narrates what is about to happen. Then the adult pauses for several seconds and looks for any signal from the child indicating that he or she understands what is about to occur. If the child responds positively, then the adult continues by acknowledging the response and continuing the routine. If the child responds and this response is interpreted as a rejection of what is to come, then the parent or teacher can honor the request by stopping the routine, skipping the step, or discontinuing the routine for a few moments and then trying again. If the child does not respond at all, the adult can repeat the tactile and verbal cues and again await a response, or continue with the routine. An example of a scripted routine during hand washing would be to sprinkle a few drops of water on the child’s fingers (tactile cue) and say "Now we are going to rinse your hands in the water" prior to actually placing the child’s hands under the water. Acknowledging a response from the child might be, "You wiggled your fingers. OK, now here’s the water." The scripted routine can also be simplified simply by not providing the initial touch/smell/movement cue. In this version the adult just pauses before each step to look for a signal of awareness from the child (Beukelman & Mirenda, 1992).

The Van Dijk method: Nurturance and movement One comprehensive program whose purpose is to ready a child for learning symbolic communication is the Van Dijk method. The Van Dijk method was originally developed for children with vision and hearing impariments (dual sensory impairments), but is currently being used with children with a variety of disabilities. It is described in detail in Beukelman & Mirenda, 1992 and Westling and Fox, 1995. The key to the Van Dijk method is the establishment of a very close and initimate relationship between adult and child. It is composed of six sequential steps, all of which are conducted as much as possible in the context of real activities, games and routines. Physical touch and movement are important components of this method.

The Early Communication Process Schweigert and Rowland developed a four-level program which they used with children who had dual sensory (both vision and hearing disabilities) and motor impairments. Each step depends on the child being able to communicate directly with the adult, or to activate a communication device directly or with a switch in order to communicate. In additon, it is important to use objects and activities that are motivating to the child. This procedure is an excellent one for children who do not enjoy social attention. (See Teaching a child to enjoy social encounters.)
|
Visually cued instruction Visually cued instruction is based on what is called "symbol exchange," in which the child requests a desired object by presenting a picture symbol of it to the adult, and exchanging the symbol for the object. It teaches intentional communication, the use of symbols and requesting simultaneously. It is an excellent approach for children who are visually oriented, and who may not be exhibiting many of the social behaviors that underly effective communication, such as eye contact or orienting one’s face towards the listener. (See Teaching a child to enjoy social encounters and Children with autism or autistic-like behaviors.) For detailed information on visually cued instruction go to:

Milieu teaching Milieu teaching consists of naturalistic methods that have traditionally been used to encourage spoken language in children. These techniques have also been found to be effective in teaching children AAC and early communication-related skills (Yoder, Warren, Kim & Gazdag, 1994). (For a detailed description of these methods, see Milieu teaching.)
|
Applied Behavior Analysis (ABA) Applied behavior analysis (ABA), also referred to as behavior modification, behavior therapy, behavioral intervention, or behavioral treatment, utilizes behaviorist principles in teaching communication. At its core, ABA analyzes every interaction into three sequential components: the action or event that triggers the communication or behavior (called the stimulus), the communication or behavior that occurs in response (called the behavior or response), and the subsequent reaction to the communicative or behavioral response that just occurred (called the consequence). For example, upon seeing a toy (the stimulus), a child may point and initiate the statement "I want that" (the response), to which the adult says "Here it is" and hands it over (the consequence).
Any of these three parts can be manipulated through teaching of the child or the partners, as well as environmental adaptations. For example the initial event or stimulus may be manipulated so as to facilitate communication. An example would be placing a desirable object on a high shelf so that the child has to request it. The response being elicited, the request for the object by the child, can be encouraged through prompting. Finally, by making sure that the consequence to the child’s behavior or response is positive and consistent—in this case promptly giving the child the object—the child has incentive to continue to respond in that manner. ABA is a component of many different types of instructional procedures. (See The Early Communication Process, Basic communicative functions, Milieu teaching, and Interrupted behavior chains.)

Basic communicative functions: Making choices, requesting, getting attention and rejecting Making choices, requesting, getting the attention of an adult, and rejecting something that is not wanted are among the first aims of a child’s communication. These four functions give children control over their own lives. Besides increasing independence, they tend to decrease the incidence of behavior problems (Durand, 1993; Robinson & Owens, Jr., 1995). They make excellent starting points in teaching communication because they are highly motivating and cognitively easy to understand. Furthermore, after the child has mastered them, they can, in turn, be used in teaching the child more advanced communication skills. Which to teach first should be determined by what is most motivating to the child. For some children it may be the ability to choose or request toys or food, or to get the attention of an adult; for others it may be to let a partner know that an object or activity is disliked. Of course, more than one function can be taught at the same time. Sometimes there is the fear that a child will abuse these skills by requesting items or attention on a constant basis, or rejecting items and activities that are medically or physically necessary. However, there are proven techniques that can be used to teach the child to delay the need for immediate gratification, and to tolerate activities and objects that are necessary but disliked. (See Children with severe behavioral issues.) In summary, a child needs to have these four communicative functions in his or her repertoire because:
|
When a child chooses "incorrectly" A general rule in teaching any of these four functions is to always respond precisely to the child’s communication. For example, if the child appears to choose a neutral or unwanted object over a highly desired one, give the child the neutral or unwanted object. The child may, in fact, have wanted the neutral or unwanted object, perhaps to examine it. Even if the child has made a mistake in choosing, not responding to the child’s explicit communication and insisting that the child to choose again contradicts what choice-making is all about. It merely indicates to the child that no matter what is communicated, he or she will eventually get a certain item. Likewise, if a child requests, instead of rejects, a typically unwanted object or activity, it is important to provide it. Either the child really did want it, or the child can learn from his or her mistake. The only way for a child to learn the power of communication, and the necessity to use it accurately, is by experiencing the consequences of his or her choices (Beukelman & Mirenda, 1992).
|
Making choices In teaching a child how to make choices, initially just one or two items may be presented to the child. The objective is for the child to communicate a preference by looking at, reaching for, or in some way indicating a desire for an object that is presented. Having communicated, the child is given the item. After the child has mastered this, the number of items can be increased, or, if the child is using an unconventional method of communicating, he or she can be taught a more conventional method of indicating his or her choice. Offering choices is also a good way to determine a child’s preferences if they are not known. What motivates a child is extremely useful information in teaching communication. It is important to look out for, and resolve, particular problems that occur in teaching choice-making.

Requesting One difference between choice-making and requesting is that making a choice requires that items be presented for selection, while requesting can be done spontaneously in or out of the presence of the desired item. Requesting is highly motivating to children since they are able to get what they want with it. For this reason it is frequently used in an initial teaching program (Beukelman & Mirenda, 1992; Goodman & Remington, 1993). A request can be general (i.e. the word "want" can be used to ask for anything), or it can be specific, for example, "want a drink," or "want milk." Often a generalized request is taught first because it is the most powerful. The drawback to this is that it may be difficult for the partner to figure out specifically what is being requested. After having mastered a general request, specific requesting may be taught, although this sometimes generates confusion. When transitioning from the use of generalized to specific requesting, it is a good idea to acknowledge the child’s general requests while teaching the newer more specific ones. For example, "You are letting me know you want to eat something. Now tell me what you would like to eat" (Reichle, York & Sigafoos, 1991; Van Tatenhove, 1987). The move from generalized to specific requesting is sometimes a good way of introducing the concept of scanning. (See Direct selection and scanning techniques and Scanning.) Excellent naturalistic methods for teaching requesting include milieu teaching techniques, and prompting and prompt-free strategies. After the child has mastered making requests in the presence of the desired item, he or she can be taught to request an item that is not visible. This can be done by removing familiar items and prompting the child to ask for them. It helps to provide clues that trigger the child’s desire for the object. For example, if a doll is ordinarily used along with a toy crib and some doll clothes, seeing just the crib and clothes may trigger the child’s desire to play with the doll. Another method is to withhold an item that is necessary to a routine or activity from the child. The activity itself stimulates the child to ask for the specific item. (See Interrupted behavior chains.) Another technique is to choose a time or situation when the child is likely to be hungry, thirsty or cold, and then prompt the child to ask for food, drink or warmer clothing. (Reichle, York & Sigafoos, 1991).

Getting attention Being able to get the attention of an adult is important, but difficult for some children. In addition, attention-getting skills are crucial for users of AAC devices that do not output sounds. For those who use speech or VOCAs, sending a message also gets the attention of a partner. However, for those who use silent methods such as gestures, sign language, communication boards, etc., the child must get the attention of the partner prior to communicating a message. In fact, visually-based AAC device users usually require a sound-based communication method for getting a partner’s attention, such as vocalization, a buzzer, a whistle, a clap, etc. (See Multimodal communication.) Another reason for teaching ways of getting a partner’s attention is that sometimes a child does not understand that this is a necessary part of communication. For some children, a first objective is to teach intentional communication. (See The first goal: Intentional communication.) Thus, initial efforts aimed at helping the child make a connection between his or her behavior and adults’ responses often mean that every communicative attempt on the part of the child results in an immediate reaction. Such a child never has the need to get the attention of the adult prior to communicating, and, thus, does not understand that this is necessary. This can be offset by incorporating attention-getting strategies into an intentional communication instructional program (Reichle, York & Sigafoos, 1991). (See The Early Communication Process.) Attention-getting can be taught using prompting and prompt-free strategies or can be included in routine-based teaching techniques.
|
Rejecting Teaching a child how to say "no" to an unwanted object or activity is a sometimes neglected communication skill. Yet, the inability to say no in an appropriate manner is frequently associated with behavior problems. When a child is not able to indicate rejection, the child may find him- or herself suddenly in the midst of an undesirable predicament, resulting in immediate and forceful rejection behavior. (See Children with severe behavioral issues.) Like requesting, rejecting can be taught initially in a general form that will serve in any situation, such as "no." When this is mastered, more specific forms can be taught, for example, "no milk" (i.e. I don’t want milk.") In teaching rejecting, it is often difficult, but important, not to remove an unwanted item or situation in response to an inappropriate behavior. This only serves to reinforce for the child that the quickest way out of the situation is to act out. By the same token, it is important to give the child a method of rejection that allows the child to escape from an unwanted situation in a quick, reliable and efficient manner. For example, vocalization, shaking one’s head, or waving a hand back and forth can be fast and easily understood by others, as opposed to locating and pushing a button on a voice output communication aid (VOCA). In teaching a child to reject, the adult must learn to recognize early the child’s current manner of rejecting. For example, the child may begin with a frown, then wave his or her hands and whine, and finally start to cry or scream. As soon as the adult notices the frown starting to appear, the child should be prompted to communicate "no," and the offending object removed immediately. In fact, because a child’s self-developed way of rejecting can occur extremely quickly in response to an unwanted item, it may be necessary to teach the child the new rejection signal outside of an actual negative situation.
Initially it may be important to honor the child’s newly learned ability to communicate a refusal at every opportunity, especially if it is replacing dangerous rejection behavior. This is difficult with regards to activities that are medically or physically necessary. If possible, remove the unwanted activity upon the request of the child, and then continue again after a pause, or break it up into smaller steps. After the child has mastered the new method of rejecting, he or she can be taught to delay the removal of the unwanted object or activity for longer and longer periods of time (Beukelman & Mirenda, 1992). (See Children with severe behavioral issues.)

Conversational skills: Initiating and maintaining a conversation In basic terms, a conversation has three parts, a beginning, a middle or body, and an ending. Each requires different skills. To begin a conversation, one has to get the attention of a partner and bring up a topic that is of interest to both parties. Maintaining the interaction requires such skills as taking turns, and being able to stay on the same topic or move smoothly to another topic of interest. Ending the interaction implies finding a point in the conversation in which it is okay to stop, and then informing the partner of one’s intention of terminating the conversation. Of these three, the first two are usually considered the more important. Children who use AAC may need systematic teaching and practice to master these skills. This is not only because they may be unfamiliar with the actual skills, but also because characteristics of AAC systems usually necessitate significant conversational adjustments by both child and partners.
|
Conversational control vs. conversational efficiency A lot of focus has been placed on the conversational imbalance that occurs between persons with and without disabilities. Persons with disabilities are known to seldom initiate, to respond primarily with short statement such as yes and no, and, overall, to occupy significantly less of the conversational space than do their partners without disabilities (Calculator, 1997; Light, 1988). This is, indeed, notable and disturbing. On the other hand, it is important to keep the entire interaction in perspective. Rather than just focusing on initiations and number of words spoken, it is worthwhile to look at the overall quality of such conversations: how long each one is, how often they occur, how engaged each party is, how much information is conveyed, etc. One study found that, in conversations between two individuals without disabilities, one of whom was asked to use AAC, the AAC users automatically became less of an initiator and more of a responder. The additional time and effort required to communicate with the AAC device caused the conversation to lose its natural timing and rhythm, and for the non-AAC partner to lose interest. For the sake of conversational flow, the AAC users naturally adopted a more passive role, relying on their partners to steer the conversation in an attempt to increase the pace. Speed of communication is, in fact, considered one of the most important factors in normalizing conversations. Studies have found that normal speakers use 150 to 250 words per minute, but that AAC users average less than 15 words per minute (Beukelman & Mirenda, 1992; Venkatagiri, 1995). In effect, conversational control and conversational efficiency appear to often be at odds with each other. What this study suggests is that merely to focus on increasing the number of initiations or the number of words output by a child who uses AAC may not necessarily be helpful, and can even be detrimental to the overall interaction. What need to be identified are the obstacles that are impeding a particular child’s conversational ability. Obstacles may include the child’s own lack of confidence, learned helplessness, conversational inexperience or lack of interesting subject matter, or may be inherent to the child’s skill in using the AAC, such as slowness or a large number of mistakes. These specific issues need to be addressed if the overall quality of the interaction is to improve.
At the same time, much can be gained by increasing partners’ sensitivity to the characteristics and needs of AAC users. Partners can be taught to increase an AAC user’s conversational control by pausing for longer periods to give sufficient time to initiate or respond, using open-ended as opposed to yes-no questions, and following the user’s lead (Farrier, Yorkston, Marriner, & Beukelman, 1985).

Initiating interactions Children with communication impairments often have difficulty initiating a communicative exchange, which has instigated much research and debate. In one study, for example, families were taught a number of different techniques to facilitate communication with their AAC-using child. The results were positive; the children became substantially more communicative, and used longer, more sophisticated responses. Yet, they did not increase their rate of initiating conversations. Learned helplessness was one factor cited in explaining why these children remained non-initiators. This suggests the importance of early intervention in the prevention of learned helplessness in children with disabilities (Basil, 1992). (See Contacting an organization for services and support.) To a large extent, initiating conversation comes with practice and self-confidence. To help a child who is not initiating due to lack of opportunity or apprehension, the following may be of assistance (Reichle, York, & Sigafoos, 1991).
|
Topic-setting strategies Beukelman & Mirenda (1992) stress the importance of providing the child with a means for bringing up new topics. This consists of providing and teaching relevant vocabulary, and giving the child an engaging way to introduce a topic of interest. They suggest collecting items that represent activities and events that are of interest to the child and putting them in a folder or book, or assisting the child in making collections of objects such as miniature cars, stuffed animals, etc. These props allow the child to introduce the topic easily and in an interesting manner. Even if the child still does not initiate, the partner, upon seeing the props, can easily bring up a subject of interest to the child by asking about them.
|
Maintaining a conversation Sensitive partners are very important in maintaining a conversation with a child who uses AAC. Some of the main reasons that a child may not hold up his or her end of the conversation include the child’s own lack of confidence, or the slowness often inherent in using AAC, particularly among beginning users. Partners may find themselves with the urge to "help" the child by doing most of the talking themselves, asking the child only questions that are quickly and easily answered, such as yes/no questions, or even terminating the interaction because it appears to be too effortful for the child. Instead, partners can make adjustments that allow and encourage the child to continue a conversation. First, it is important to have a conversation that is of interest to both parties. This could involve the exchange of new information, the discussion of a familiar story or topic, or it could be a game or routine that both parties enjoy. Without being rigid about it, partners can provide the child with longer pauses, ask more open-ended questions (i.e. questions that cannot be answered by just one or two words), and expect longer responses from the child. If a familiar story, game or routine is being used, the partner can add variations in order to expand the child’s repertoire. Finally, the partner can follow the child’s lead by allowing the child to set the topic and then following along. Children are known to have a greater attention span and to communicate more on topics which they, as opposed to their partners, have introduced (Calculator, 1988b; Yoder & Davies, 1990; Yoder & Davies, 1992a).
A specific strategy that encourages a child to continue a topic of conversation starts by encouraging the child to initiate a subject of interest through the use of pictures, props or other means. (See Topic-setting strategies.) The partner responds to the child’s initiation, and then adds a question or comment about the topic, to which the child is expected to respond. After the child responds, the partner follows up in the same manner (Beukelman & Mirenda, 1992; Westling & Fox, 1995) OTHER RESOURCES:

Teaching sentence structure After a child has mastered basic one- to three-word phrases, it may be time to begin encouraging the child to start using more complete sentences. Sometimes this involves introducing a new, more advanced AAC system. For example, communication boards may not facilitate the use of grammatically correct sentences, whereas sign language or a voice output communication aid (VOCA) will. Essentially, the type of AAC and symbol system used will have an affect on how the child is taught sentence structure. If a VOCA is used, choice and organization of vocabulary become crucial in this endeavor. (See Vocabulary selection strategies and Organizing vocabulary for speed.) OTHER RESOURCES:
