Teaching Sign Language Amy McGinnis POAC of PA November 10, 2005 After this workshop, you should be able to…. • Identify the verbal operants according to Skinner’s analysis • Evaluate the need for augmentative communication • Select a form of augmentative communication, based on the pros/cons • Develop a child’s mand repetoire through sign language Verbal Behavior Terminology • Skinner analyzed language according to function rather than meaning • Learning and using this terminology will improve your ability to teach verbal behavior to individuals with autism • 4 primary operants: – – – – Mand Tact Intraverbal Duplic (echoic / mimetic) Mand • The verbal response of requesting (i.e. “I want juice.”) • Mands are reinforcer specific (reinforced by getting what you asked for) • Teaching someone to mand items, activities, or objects will lead to a higher rate of talking and will support the development of the other classes of verbal responses (i.e. tacts, intraverbals, etc.) Tact • The verbal response that is closest to labeling (i.e. “That’s a red ball.”) • Involves labeling items that are present in the environment • When a learner says or signs what he sees, hears, touches, tastes, smells, etc., he is tacting. • The reinforcement for this response is not specific to what is said and is usually social reinforcement of some type such as acknowledgement of what is said or praise Intraverbal • The verbal response to someone else’s verbal response (i.e. When someone asks what you had for breakfast, “I had juice” is an intraverbal) • Involves discussing items that are not present in the environment (i.e. past events) • This class includes answering “wh” questions and filling in the blanks (i.e. “Twinkle, twinkle little __”) • Intraverbal skills are essential to carrying on a conversation Duplic • Involves imitation • Mimetic = motor imitation – Copying someone else’s movements • Echoic = vocal imitation – Repeating what someone else says Receptive • The receptive response class refers to understanding what someone else says • During NET this might include delivering requests to: – Perform actions: “Stand up” (receptive commands) – Identify an object by touching it or giving it to the teacher “Touch Elmo” (receptive ID) Assessment of Basic Language and Learning Skills Skills Tracking System Student: Assessor Date Color Code C52 C51 C50 C49 C48 C47 C46 C45 C44 C43 C42 C41 C40 C39 C38 C37 C36 C35 C34 C33 C32 C31 C30 C29 C28 C27 C26 C25 C24 C23 C22 C21 C20 C19 C18 C17 C16 C15 C14 C13 C12 C11 C10 C9 C8 C7 C6 C5 C4 C3 C2 C1 ABLLS REGISTRATION # B21 B20 B19 B18 B17 B16 B15 B14 B13 B12 B11 B10 B9 B8 B7 B6 B5 B4 B3 B2 B1 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A Cooperation & Reinforcer Effectiveness B Visual Performance D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 C Receptive Language D Imitation F27 F26 F25 F24 F23 F22 F21 F20 F19 F18 F17 F16 F15 F14 F13 F12 F11 F10 F9 F8 F7 F6 F5 F4 F3 F2 E9 E8 E7 E6 E5 E4 E3 E2 E1 F1 E Vocal Imitation F Requests G42 G41 G40 G39 G38 G37 G36 G35 G34 G33 G32 G31 G30 G29 G28 G27 G26 G25 G24 G23 G22 G21 G20 G19 G18 G17 G16 G15 G14 G13 G12 G11 G10 G9 G8 G7 G6 G5 G4 G3 G2 G1 G Labeling H42 H41 H40 H39 H38 H37 H36 H35 H34 H33 H32 H31 H30 H29 H28 H27 H26 H25 H24 H23 H22 H21 H20 H19 H18 H17 H16 H15 H14 H13 H12 H11 H10 H9 H8 H7 H6 H5 H4 H3 H2 H1 H Intraverbals I9 I8 I7 I6 I5 I4 I3 I2 I1 I Spontaneous Vocalizations Modes of Communication Topography Based • Involves producing a unique response form for each word • Examples: – Vocalizations – Sign language Selection Based • Involves scanning an array of pictures, words or symbols and selecting one via point/touch • Examples: – PECS – Dynavox – Go Talker – Intellikeys Candidates for Augmentative Communication • Limited ability to accurately echo sounds and words • Most attempts to talk are unintelligible to an unfamiliar listener • Most words are unintelligible without contextual cues Evaluation • What if a child has some vocalizations? • The Unfamiliar Listener Test – Have an adult who is not familiar with the child sit with his/her back turned. Have the listener write down what he/she hears the child say. – If most words are not understood, pursue augmentative communication Choosing an Augmentative Communication System • Ease of Acquisition for the Learner: – Easiest & fastest to learn • Development of Vocalizations: – Choose the system that is most likely to facilitate the development of vocal behavior (talking). • Full Linguistic System: – Choose the system that allows for verbal behavior across all the meanings (operants) of words just in case the child does not develop vocal behavior as his/her sole form of communication. Advantages of Picture Systems • Listener does not need special training • Simple matching-to-sample may make initial acquisition easier • No special shaping required for individual responses • Pointing/touching is often already learned or is easily learned Disadvantages of Picture Systems • Rely on environmental support to communicate • No “picture system” community exists • Pointer needs audience close by • Symbols/icons become increasingly abstract as word complexity increases • Selection based, often does not improve speech • Slow, not conducive to conversation • Cannot be used to teach many operants What can we teach with picture systems? • Mands – can teach, but cannot fade to MO level • Tacts - often cannot teach true tacts Intraverbals – often cannot teach true intraverbals • Receptive ID – can teach independent of system • Motor imitation – can teach independent of picture system Picture Systems: Assessment of Basic Language and Learning Skills Skills Tracking System Student: Assessor Date Color Code C52 C51 C50 C49 C48 C47 C46 C45 C44 C43 C42 C41 C40 C39 C38 C37 C36 C35 C34 C33 C32 C31 C30 C29 C28 C27 C26 C25 C24 C23 C22 C21 C20 C19 C18 C17 C16 C15 C14 C13 C12 C11 C10 C9 C8 C7 C6 C5 C4 C3 C2 C1 ABLLS REGISTRATION # B21 B20 B19 B18 B17 B16 B15 B14 B13 B12 B11 B10 B9 B8 B7 B6 B5 B4 B3 B2 B1 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A Cooperation & Reinforcer Effectiveness B Visual Performance D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 C Receptive Language D Imitation F27 F26 F25 F24 F23 F22 F21 F20 F19 F18 F17 F16 F15 F14 F13 F12 F11 F10 F9 F8 F7 F6 F5 F4 F3 F2 E9 E8 E7 E6 E5 E4 E3 E2 E1 F1 E Vocal Imitation F Requests G42 G41 G40 G39 G38 G37 G36 G35 G34 G33 G32 G31 G30 G29 G28 G27 G26 G25 G24 G23 G22 G21 G20 G19 G18 G17 G16 G15 G14 G13 G12 G11 G10 G9 G8 G7 G6 G5 G4 G3 G2 G1 G Labeling H42 H41 H40 H39 H38 H37 H36 H35 H34 H33 H32 H31 H30 H29 H28 H27 H26 H25 H24 H23 H22 H21 H20 H19 H18 H17 H16 H15 H14 H13 H12 H11 H10 H9 H8 H7 H6 H5 H4 H3 H2 H1 H Intraverbals I9 I8 I7 I6 I5 I4 I3 I2 I1 I Spontaneous Vocalizations Advantages of Sign Language • May help to develop motor imitation • Stimulus & response often resemble each other, providing a built in prompt (iconic relation) • Topography based, like speech • Single stimulus and single response relation, like speech • Community of signers already exists • Can be used to teach all operants Disadvantages of Sign Language • Parents & teachers must learn the child’s signs • Parents & teachers need to use sign language when interacting with the child • Parents & teachers must teach/shape each individual sign Sign Language: Assessment of Basic Language and Learning Skills Skills Tracking System Student: Assessor Date Color Code C52 C51 C50 C49 C48 C47 C46 C45 C44 C43 C42 C41 C40 C39 C38 C37 C36 C35 C34 C33 C32 C31 C30 C29 C28 C27 C26 C25 C24 C23 C22 C21 C20 C19 C18 C17 C16 C15 C14 C13 C12 C11 C10 C9 C8 C7 C6 C5 C4 C3 C2 C1 ABLLS REGISTRATION # B21 B20 B19 B18 B17 B16 B15 B14 B13 B12 B11 B10 B9 B8 B7 B6 B5 B4 B3 B2 B1 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A Cooperation & Reinforcer Effectiveness B Visual Performance D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 C Receptive Language D Imitation F27 F26 F25 F24 F23 F22 F21 F20 F19 F18 F17 F16 F15 F14 F13 F12 F11 F10 F9 F8 F7 F6 F5 F4 F3 F2 E9 E8 E7 E6 E5 E4 E3 E2 E1 F1 E Vocal Imitation F Requests G42 G41 G40 G39 G38 G37 G36 G35 G34 G33 G32 G31 G30 G29 G28 G27 G26 G25 G24 G23 G22 G21 G20 G19 G18 G17 G16 G15 G14 G13 G12 G11 G10 G9 G8 G7 G6 G5 G4 G3 G2 G1 G Labeling H42 H41 H40 H39 H38 H37 H36 H35 H34 H33 H32 H31 H30 H29 H28 H27 H26 H25 H24 H23 H22 H21 H20 H19 H18 H17 H16 H15 H14 H13 H12 H11 H10 H9 H8 H7 H6 H5 H4 H3 H2 H1 H Intraverbals I9 I8 I7 I6 I5 I4 I3 I2 I1 I Spontaneous Vocalizations Sign Language for Learners with Autism • Sign language teaching may lead to improved vocal verbal behavior in children who are vocal but engage in frequent delayed echolalia or video-type or for whom the development of more abstract verbal behavior (adjectives, prepositions, etc.) are difficult to acquire. • Sign may be acquired more easily (faster and accurately) than picture symbol systems and with greater facilitation of mand stimulus selection (receptive language) Sign Language for Learners with Autism • There is convincing evidence that sign language acquisition with spoken words accompanying sign (total communication) may lead to vocalizations with some children. • Children who already possess some vocal imitation skill are more likely to develop vocal verbal behavior as a result of sign language acquisition. • Almost all children with autism can learn to sign despite motor imitation difficulties Begin Sign Training by Teaching Mands • Identify items and activities that are reinforcing for the learner • Select reinforcers that instructors can easily control and that provide many opportunities to mand (request) • Determine the manual sign for each of the reinforcers the child will learn to mand for Steps to Choosing Target Mands 1. Decide how many mands to target at a time. Always teach more than 1 at a time. 2. Choose mands from a variety of motivational categories. Do not teach items from only one category at a time (ie: all foods) 3. Look up the sign for each item 4. Avoid teaching signs that look similar (“signs that rhyme”) Choosing Target Mands • Do NOT teach the following until the learner can mand for many items: – – – – – – – – – – Yes/no More Finished Please Potty Help Eat Drink Help Carrier phrases (“I want__.” “Give me__.”) Sources for Signs • www.verbalbehaviornetwork.com • www.Commtechlab.msu.edu/sites/aslw eb/index.html • Garlic Press Flash Cards • Sign language books Organization • It is important that everyone who spends time with the learner knows his/her signs • Find a way to keep everyone updated on the learner’s signs – Photo album – Video – Flash cards on a metal ring Modifying Signs • Analyze which movements will be easiest for child • Try to keep the modified version of the sign as close to the true ASL sign as possible • When you model the sign, be sure to model the sign in its modified form What about children with poor fine motor skills? • Children with poor fine motor skills can still learn to sign • Sign language may actually help the child to improve his/her fine motor skills • Initially, it may be necessary to modify signs MAND Antecedent Learner Behavior Reinforcer Motivation (MO) Verbal Behavior Specific to the MO (Thirsty) (Signs water) (Gets water) Teaching Mands: MODEL PROMPT GIVE • • • • • Establish MO (learner WANTS reinforcer) Model the sign Physically prompt sign (if necessary) Give the reinforcer Be sure to say the word at least 3x • Gradually fade prompts with reinforcer present Eventually fade the reinforcer from sight (cover & mand) • Rules for Teaching Sign • Contrive MO’s by delivering some reinforcement for “free” • Hold up choices to establish MO • Prompt mands only for items learner wants • Avoid speaking first before learner’s mand • Allow learner to enjoy reinforcer • Use appropriate pace to keep learner engaged Rules for Teaching Sign • Fade prompts gradually • Give differential reinforcement for more independent signs • Initially, reinforce independence over accuracy • Fade only strong mands from item to MO level (item not present) Scrolling • Scrolling occurs when a child signs the incorrect sign or a series of incorrect signs when trying to request something • Never reinforce a child for scrolling • Prompt their hands down to a neutral position for 2-3 seconds • Model and physically prompt the correct sign • Reinforce Common Mistakes When Teaching Sign • Not enough training trials are provided • Failure to fade prompts • Individual operants are never established and responses remain multiply controlled • Lack of a progressive, systematic curriculum • Failure to require signs outside of therapy sessions • Failure to sign to the child • Failure to build a community of signers Common Mistakes When Teaching Sign • First signs taught are not mands • First signs taught are too complex or overly generalistic (mega-mands!) • First signs may resemble each other too closely • First signs may involve complex motor movements Transitioning from Sign to Vocal Mands • When the learner can independently sign for a highly motivating item when the item is present, it is possible to shape a vocal mand for this item using target approximations. • Pick a target approximation (TA) for that word. • The target approximation should be the child’s best vocal approximation for that word. Shaping Vocal Mands 1. Present the item & establish that the learner wants it 2. When the learner signs, do not give the item right away 3. Instead, model the vocal word three times with one-second intervals between each presentation of the word. 4. Do not give the item to the learner until s/he makes at least the sound that you set as the TA, or immediately following the third presentation of the word. Shaping Vocal Mands 5. ALWAYS give the item by the 3rd presentation of the word 6. Once the child is consistently making a better vocal approximation, change the TA to that better approximation. It is very important for everyone involved to be very consistent in his or her reinforcement on the TAs. 7. Do not allow the child to stop signing until the vocal mand is clear, strong, and consistent For More Information… • For more information regarding how to teach verbal behavior skills across the operants, please visit www.poacofpa.net to obtain the schedule for the remaining free workshops
