The Effects of Sign Language on the Vocal Responses of a Child with Autism.
… measured the effects of sign language on the vocal responses of its users. This study employed a multiple baseline design to evaluate the effects of sign language on the vocal responses of a four-year-old boy with autism. Results indicate that a reinforcement contingency placed only on sign …

Vocal responses of Blue Jays (Cyanocitta cristata) to raptors that differ in predatory threat
… 2015, I recorded and subsequently analyzed the vocal responses of Blue Jays to study skins (N = 7) that varied in size and the level of threat they pose. Experiments were conducted at seven different locations in Madison County, Kentucky. The mean number of jays present was 2.6 (range = 1 – 6), …

Vocal responses of adult Eastern Bluebirds (Sialia sialis) to potential nest predators and the behavioral responses of nestlings
… However, few investigators have examined the responses of nestlings in cavity nests to the anti-predator vocalizations of adults. Therefore, the objectives of my study of cavity-nesting Eastern Bluebirds <em>(Sialia sialis)</em> were to examine (1) the vocal responses of adult Eastern …

The Acquisition of Mand and Tact Responses
… to assess the acquisition of mand and tact responses as a result of mand or tact training. Three subjects were tauqht vocal responses corresponding to objects as requests (mands)or as labels (tacts). Responses in the untrained repertoire were also assessed. The results indicated that …

Using video modeling to teach complex play sequences to children with autism.
… of video modeling on repetitive motor and vocal responses and skill generalization to other settings for children with low-functioning autism/ developmental disabilities. A multiple baseline across 3 play sequences was implemented with 3 males. Results indicate that 2 acquired vocal and …

Perceived Predation Risk And The Responses Of Adult And Nestling Tree Swallows (tachycineta Bicolor)
… Although several investigators have examined the responses of nestlings of species with open-cup nests to the anti-predator calls of adults, few have conducted such studies with cavity-nesting species of birds. Therefore, the objectives of my study were to examine the vocal responses of …

Vocal Variability in Autism Spectrum Disorders: Assessment and Intervention to Increase Novel Vocalizations in Non-Verbal Children
… with the acquisition of new skills, including vocal communication. For many children with ASD who are unable to imitate others and who have limited vocal repertoires, few vocal training interventions are available. Research on operant variability, however, indicates that the direct …

Effects of auditory feedback and real-time visual feedback on second language tone learning
… change in pitch is fed back to speakers during vocalization, has been used to investigate how sensory information affects the way we control our speech motor activities. Pitch-shift responses (vocal responses to auditory perturbation) have reflex-like properties and are hard to suppress. So …

Effects of celeration rate on behavioral fluency
… with money arranged on VI schedules for correct responses with inter-response times within a programmed range. This procedure allowed response rate and celeration rate to be controlled precisely while maintaining a similar reinforcement rate across conditions. Each group of subjects received one …

Effects of Gender and Age on Vocal Modeling and the Pitch-Matching Accuracy of Elementary School Children
… to determine the effects of gender and age on vocal modeling and the pitch-matching accuracy of young children. Ninety-three students in grades one through five were tested on their ability to respond vocally to one of three different vocal models. Of the 93 participants, 53 were female and 40 …

Slamming into the visceral pleasure of language : the value of disordered spaces and its impact on contemporary vocal landscpes
… to spoken language. In a disordered space, vocal delivery is foregrounded as physical activity and has a re-patterning effect on the vocal landscapes of young actors. A disordered space co-opts elements from the vocal art forms of the popular phenomenon of the Spoken Word Movement. …

Adventitious differential reinforcement of emergent sample-specific behavior and common coding in pigeons' matching-to-sample
Matching-to-sample performance is enhanced if responses to the sample stimuli are required, and further enhanced if different responses are required to the different samples. Even when not required, differentiated sample responding may emerge spontaneously, either overtly or as an hypothesized …
