NATURAL GESTURES
WHY TEACH NATURAL GESTURES? Theoretical reasons: Developmentally occur prior to symbolic communication Thought to pave the way for symbolic communication Provide opportunities for linguistic input
WHY TEACH NATURAL GESTURES? Practical reasons: Readily understood by numerous partners No extra equipment is needed Can be used across many different contexts Evidence -base: easier to teach than some forms of symbolic communication
PRELINGUISTIC MILIEU TEACHING Communication interactions occur within motivating, naturalistic teaching routines Routines provide opportunities for a child to use natural gestures and vocalizations to greet, request, reject, comment in authentic contexts Communication partner responds to a child’s communicative attempts in contingent ways Primary targeted outcome is to increase a child’s rate of communication
ADAPTATIONS TO BASIC PMT STRATEGIES FOR CHILDREN WITH DB Utilize augmented input strategies, including touch cues and object cues Incorporate hand-under-hand strategies Emphasize tactile and vestibular activities
ADAPTATIONS TO BASIC PMT STRATEGIES FOR CHILDREN WITH DB Involve indication of directionality (of a communication act) through alternative orienting responses or whole body orientation--not just eye gaze Incorporate environmental adaptations to facilitate the use of a child’s residual vision and hearing
PARTICIPANTS 12 children from NE Kansas / NW Missouri, recruited with assistance of the KS and MO state deaf-blind projects Documented vision and hearing losses 3 to 7 years of age at study’s inception Communicated at rate of less than one communicative act / minute Communication skills at nonsymbolic level
RESEARCH REPLICATION 6 children from Indiana Recruited through the Indiana Deafblind Services Project-staff of which provided all intervention sessions Participants selected according to same criteria as applied in main study
KEY FINDINGS Eleven children (main study group) and six children (replication group) completed intervention ALL children (both groups) showed increases in rates of communication Nine children (main study) and four children (replication) successfully achieved, or exceeded, exit criterion through initiations / responses Two children (each group) exited intervention after 9 months (i.e., only participants who have significant motor challenges, in addition to other disabilities)
# COMMUNICATION ACTS / MIN. ParticipantBaselineEND: Intervention HOWA ROTL MANJ MACB HALD BROI LOCM OVZJ CAIE
FINDINGS (continued…) Increases in communication rate, for participants (n = 9) who do not also experience significant motor challenges, ranged from: 0.55 more CA / min. to 1.72 more CA / min. (25 to 77 more comm. acts in a 45 min session) Average Increase in communication rate, for these participants, was 1.31 more CA / minute (59 more comm. acts in a 45 min session)
# COMMUNICATION ACTS / MIN DATA FROM REPLICATION SITE (INDIANA) ParticipantBaselineEND: Intervention BUCJ MINS COLD PRAB
FINDINGS (continued…) REPLICATION SITE (INDIANA): Increases in communication rate, for participants (n = 4) who do not also experience significant motor challenges, ranged from: 0.42 more CA / min. to 1.08 more CA / min. (19 to 49 more comm. acts in a 45 min session) Average Increase in communication rate, for these participants, was 0.87 more CA / minute (approx. 40 more comm. acts in a 45 min session)
FINDINGS (continued…) ALL children (in BOTH the main study group and the replication study group) demonstrated both an increased number and greater diversity in communication forms

SUMMARY OF KEY FINDINGS ADAPTED PMT was effective in increasing: Prelinguistic communication rate Diversity of individual learners’ nonsymbolic communication forms and functions--particularly for those learners who demonstrate good motor skills HOWEVER… Effects did NOT generalize to different contexts
