In the Ingvarsson (2010) study, they used echoic prompting as well as constant prompt delay to mand for answers to questions by saying “I don’t know please tell me”. In this study they took baseline data by asking 56 questions. They would mark these questions as known or unknown, depending on if the child answered the question. During the training phase, the experimenter used echoic prompting and constant prompt delay. The experimenter would ask the child a question that was labeled unknown in the baseline phase. After the experimenter would ask the question, he would immediately provide a verbal prompt. The verbal prompt that was used was “I don’t know, please tell me.”. After the participant response was modeled correctly, the experimenter would model the correct answer. If the child did not repeat the correct answer, the experimenter would provide a prompt. When the child stated the correct answer, the experimenter would provide descriptive praise. The results of this study showed that following the intervention 2 participants had quick acquisition and generalization. One participant gains did not meet acceptable levels until edibles items were made contingent. Lastly, one other participant’s correct answers did not increase until after direct training of correct answers. Overall, these results provide a replication and extension of the Ingvarsson et al. (2007) study. (Ingvarsson, 2010) The following studies looked at interventions used to help in language development using Discrete Trial Training. This study done by Krantz, Zalewski, Hall, Fenski & McClannahan (1981) was performed to teach complex language productions. They taught children to describe objects and pictures. This was done using four-term sentences. The children were also taught how to answer numerous why, what, and how questions about immediate events and then past events with
Incidental teaching focuses on child-initiated interactions. (Hall, 2013) Incidental teaching is used to increase skills of individuals with autism spectrum disorders. (Hall, 2013) A study done by Hart and Risley (1975) looked at the incidental teaching process used at the preschool age to aide in teaching language. Incidental teaching has been the most frequent strategy that has been used to teach language. When using incidental teaching a child’s request may be verbal or nonverbal. Examples include reaching for an object that is out of one’s reach, requesting food or a toy or calling an adult’s name. There is a series of decisions that an adult can use to respond to the child’s request. These choices include: if the occasion should be used for incidental teaching: if so then a choice regarding the language behavior that is obtained from the child, and then a choice has to be made concerning the cue that will be used to initiate instruction, the cur could be focus of attention by itself, or in addition to the focused attention a verbal cue as well. If the individual does not respond to the cue, then a choice concerning the degree of prompt to be used, the “fullest degree: a request for imitation; medium degree: a request for partial imitation, or minimal degree: a request for the terminal language behavior.” (Hart & Risley, 1975) This study was performed on boys and girls between the ages of four years old to five years old. The baseline procedures ensured that the children had a variety of vocabulary for use in sentences. The sentences that they were taught was “I want x so I can y.” The second step of the procedure was the use of incidental teaching of compound sentences directed to teachers. After thirty-six days of school, the incidental teaching began to occur when the children needed assistance in trying to get different preschool materials.
The child is at stage three linguistic speech in oral development (Fellows & Oakley, 2014). They show evidence of this in both their receptive and expressive language meeting the criteria for this stage (Fellows & Oakley, 2014). They show evidence of their receptive language by their ability in being able to understand opposites (Fellows & Oakley, 2014). While they had some issues with the differences between soft and scratchy they were able to demonstrate the differences between big and little several times during the dialogue. They showed evidence of their expressive language by their use of telegraphic speech, expanding vocabulary and in the ability to take in turns of speaking and listening (Fellows & Oakley, 2014). Telegraphic
The most typical component of ABA used is positive reinforcement, which studies have shown to be an effective technique within a variety of settings and circumstances. Ferguson and Rosales-Ruiz (2001) conducted a study in which they utilized positive reinforcement in order to modify the behavior of horses. Prior to the study, the five horses observed were demonstrating inappropriate behaviors while loading into a trailer, which can be dangerous for both caregivers and the animals (p. 409). In order to deter these behaviors, the researchers provided the mares with preferred foods as positive reinforcement as the behavior was gradually shaped. They began by reinforcing approximate behaviors until the desirable behavior was achieved. At first, the horses were reinforced with food for several trials if they simply stepped near the entryway and touched their noses to a towel (the distance marker) without maladaptive behaviors. Over the series of eight steps, the target was pushed farther back into the trailer and the horses were reinforced for each successive approximation (p. 412). After all of the trials, each horse ended up completing the tasks and the inappropriate behaviors thereafter fell to zero. This was completed simply through the use of shaping and positively reinforcing the successive approximations of the behavior without the use of punishment or negative reinforcement (p. 421).
Tarbox, Madrid, Aguilar, Jacobo, and Schiff (2009) researched this behavioral technique in a study involving three children with Autism who had echoic language deficits. Each of these students (ages 3, 5, and 7) could only produce single-syllable approximations of words prior to this study (Tarbox et al., p. 902). Three child-relevant, di- and tri-syllabic words were selected as targets of mastery for each student. A chaining procedure was then utilized by in-home ABA therapists to allow gradual, yet effective mastery of the words. Each word was broken down into sounds, and each sound was a step in the chaining process. The therapist would then verbally model a component of the word. Once that step was mastered, immediate reinforcement was provided and the next step would begin. The final step linked all of the components together in order to form the entire echoic. Out of the nine words total between the three participants, eight were mastered within only nine sessions. One word took a participant 35 sessions to master; however, all of the words reached mastery level and eight were maintained long-term (p. 903). These findings suggest that chaining procedures can be effective methods of increasing word-lengths in children with Autism who struggle with echoic language. Since language-production is a common deficit for those with ASD, this method of chaining is often utilized in ABA for language acquisition and is many times deemed effective (Tarbox et al., p. 904).
Establishment consisted of teaching the children correct placement of articulators to produce the targeted speech sound across all word positions. The randomized-variable practice began once the child could produce the sound 80% of the time in certain syllables. It usually took children 1-5 sessions to complete the establishment phase. Random teaching tasks such as imitated single syllables, imitated single words, nonimitated single words, imitated two-to-four word phrases, nonimitated two-to-four word phrases, imitated sentences, nonimitated sentences, and storytelling or conversations were selected in the second phase. Participants remained in this phase until they obtained 80% mastery across two
I am currently a ABA therapist and I've been working in this field for two years. I have worked with children from ages 2 to 14 years old with different diagnoses. Most of my clients are autistic but I've worked with children with Down syndrome, ADD, ADHD, ODD, OCD, and developmental delay. I have opportunities to reinforce positive behaviors and help extinguish negative behaviors. I also am able to engage in incidental teachings, run knowledge based programs, and interactions using verbal and non verbal communication. My career plan is to become certified as a BCBA and become a BSC. As a BSC I will be able to help many more children on a high scale.
Autism is a neurodevelopmental disorder that effects the brains development. It is characterized by affecting communication, cognition and social interaction. The spectrum of the disorders ranges from a mild condition called Asperger’s syndrome to a more severe form, which severely impairer’s development. The Office of Communications and Public Liaison states that the disorder affects one and eighty-eight children, however ASD effects boys more frequently than girls (Office of Communications and Public Liaison, 2013). ASD emerges in all age, ethnic and socioeconomic groups. The significant varied character and severity of the disorder is why ASD is considered a spectrum that poses a broad range of symptoms.
This essay is about a child’s development and learning, focusing primarily on language development. It will describe the main stages of developmental "milestones" and the key concepts involved for children to develop their language skills, discussing language acquisition and social learning theory. The essay will also look into the key theorists involved in language development, primarily Vygotsky and Chomsky, and how these theories have had an impact on the way society views language and their implementation within schools. The essay will describe the factors affecting language development, both biological and environmental. While also discussing key arguments among theorists, one being the nature vs nurture debate, and how these play a part in the teaching in schools.
Cognitive Development and Language Skills Development “Cognitive development underpins all the other aspects of development as children start to explore and make sense of the world around them. It is closely linked to the development of language and communication skills as children interact with the people around them.” There are many theories written on the subjects of cognitive development and language and communication. These theories vary in several ways, but they all seem to make the link between the too subjects. Childcare settings put these theories into practise in a lot of ways, sometimes without even realising it, just through conversation.
Language isn’t intentionally taught, but more picked up as the child grows up; “we do not learn words from dictionaries, we take them from conversations that subsequently shape our understanding of the world” (Thompson, 2009). Because of this, educators need to give time for children to practice their language skills. That doesn’t happen when children are doing skill-and-drill exercises over a concept, but rather when they are playing with their peers. Early educators can help facilitate this language development by introducing and teaching children new words and phrases.
There are three main theories of child language acquisition; Cognitive Theory, Imitation and Positive Reinforcement, and Innateness of Certain Linguistic Features (Linguistics 201). All three theories offer a substantial amount of proof and experiments, but none of them have been proven entirely correct. The search for how children acquire their native language in such a short period of time has been studied for many centuries. In a changing world, it is difficult to pinpoint any definite specifics of language because of the diversity and modification throughout thousands of millions of years.
How do children acquire language? What are the processes of language acquisition? How do infants respond to speech? Language acquisition is the process of learning a native or a second language. Although how children learn to speak is not perfectly understood, most explanations involve both the observations that children copy what they hear and the inference that human beings have a natural aptitude for understanding grammar. Children usually learn the sounds and vocabulary of their native language through imitation, (which helps them learn to pronounce words correctly), and grammar is seldom taught to them, but instead that they rapidly acquire the ability to speak grammatically. Though, not all children learn by imitation alone. Children will produce forms of language that adults never say. For example, “I spilled milk on hisself” or “Debbie wants a cookie”. This demonstrates that children have the desire to speak correctly and have self-motivating traits to communicate. This supports the theory of Noam Chomsky (1972)-that children are able to learn grammar of a particular language because all intelligible languages are founded on a deep structure of universal grammatical rules that corresponds to an innate capacity of the human brain. Adults learning a second language pass through some of the same stages, as do children learning their native language. In the first part of this paper I will describe the process of language acquisition. The second part will review how infants respond to speech.
Children go through a number of different stages as language develops. According to Craig and Dunn, (2010), “Even before birth, it appears that infants are prepared to respond to and learn language” (p. 112). Children develop these skills quickly with nature and nurture influences. Researchers have proposed several different theories to explain how and why language development occurs. This paper is an overview of the process of early childhood language development with research evidence supporting the information stated.
The aim of this essay is to explore language acquisition and compare and contrast different theories of language acquisition and language development. Language in its most basic form is used to communicate our needs and wants. It encompasses a range of modes of delivery including signing, spoken and written words, posture, eye contact, facial expressions and gestures. So how do we learn ‘language’? Are we born with the skills for communication, or is it something that we have to learn or have taught to us? Four theories are looked at in this essay to determine how children acquire and then develop language. These theories include behaviourist, nativist, cognitivist and sociocultural. This essay will highlight some similarities and differences in each theory and what impact these have on a child’s acquisition and development of language. Lastly we will look at the implications of these theories when working with children. Can a classroom teacher deliver a quality literacy program based on just one of these theories or does it need to incorporate components of all four? Sims, (2012) pp. 21 states ‘’High-quality learning experiences in the early years of life enhance children’s cognitive and language skills’’. This places a great responsibility on educators and teachers alike to provide an environment which is rich in learning opportunities that will encourage both the acquisition and development of language.
Further in this term-paper I am going to describe the stages in child language acquistion starting from the very birth of an infant till the onset of puberty.
