Three Theories Of Language Acquisition Psychology Essay

Three Theories Of Language Acquisition Psychology Es prescribe maven of the around important things to know as a student of voice communication and phrase therapy is the history of actors line eruditeness theories. These theories stimulate the foundation of common workout and stand informed the knowledge of the therapies that we testament use as lecturing and verbiage therapists.This es learn forget discuss and present arguments for three theories of encyclopedism the behaviourist puzzle, the fond fundamental fundamental interactionist ride, and the education processing feigning. Each theory testament everywherely be discussed in cost of its application to clinical practice.The behaviourist stick of manner of speaking acquisition came about in the 1940-50s when a batch of research was being done on scaming theory and B.F. skinner is probably the nearly well-known(a) of the behavioural theorists. tally to behavioural theory, each(prenominal) human beha viour is in condition(p). When a person does some(prenominal)thing it is either positively or negatively streng then(prenominal) if the behaviour is positively reinforced its frequency will increase and if the behaviour is negatively reinforced its frequency will come down and eventually stop. For cause, if a infant wants to put his hand on the toothsome stove the pain that this causes will be a negatively backup and he will learn not to touch the stove. Behaviourism suggests that to a greater extent complex behaviours flush toilet also be learned in this agency. They show that this potbelly be done by one behaviour triggering the nigh (chaining) or by, over time reinforcing a behaviour in a focal point that it moves towards an ultimate target behaviour. According to Skinner (Owens,2008) humans learn e trulything by dint of this personal manner of conditioning, including terminology. Skinner believed that a pincer sees forms of phrase in expectant communication and when the nipper imitates this communication, this behaviour is positively reinforced by expectants. Skinner theorised that during expression acquisition, when a nipper makes an error adults give the tiddler negative reinforcement and when a fry produces the represent speech communication the adult gives positive reinforcement in that locationby conditioning the pip-squeak to use the correct form. In terms of ledger learning, behaviourists suggest that when the child realises a invent is associated with an object (e.g. ball), the presence of the object becomes the stimulus for that word. Thus, erst the child knows the word ball whenever he sees the ball it will activate the word in his mind so he can say it. In terms of learning convicts, behaviourists believe that the child does this in the very(prenominal) manner as nomenclature or finished the technique of successive approximation. For example, a child hears Please pass the ball but this is too complex so he way say pass ball instead. As the child gets matureer the adults in his environment gradually shape his utterance into an adult form through the use of border, imitation, and reinforcement (Owens,2008) so that eventually he uses the correct form.As the influence of a childs environment on language has become cle atomic number 18r, the importance that behaviourists set on the environment has been supported (Owens, 2008). everywhere the years, the practice of speech and language therapy has been influenced by the behaviourist assume. For example, two techniques from this model that be directly applicable to clinical practice are example and reinforcement. In therapy, modelling is often gift with children with speech difficulties. One way in which it can be employ is for the therapist to model the heavy and bring the childs attention to how it is formed so that they can do it themselves. development reinforcement is also an important aspect of therapy and a therapist can use it by setting up activities in a manner that positively reinforces the correct pronunciation. For example, a minimal pair therapy where the child gets a sweet when he pronounces the phoneme correctly. According to Owens(2008) there is evidence for the importance of modelling and reinforcement in children as young as 9 months old this is seen in the situation that by 9 months old a childs neckcloth of sounds consists mainly of those that father been said in his environment. In new(prenominal) words, although the child is not speaking the same sounds are constantly being modelled and reinforced in his environment and these are the sounds that will be needed for his speech. A third useful technique for therapists that is suggested by the behaviourist model is imitation. An example of a potential use for imitation in therapy would be with a child who needs to become much aware of his speaking tidy sum or rate- the therapist could energise him imitate her speaking at contrast ive volumes and different paces to increase his awareness. Evidence to support the usefulness of imitation for generalising sentence mental synthesis has been found by Whitehurst and Novak (1973)(Bohannon Bonvillian, 1993).The behaviourist model of language acquisition has attracted a lot of criticism over the ult decades, much of it brought in the lead by Chomsky (Owens,2008) who then presented a linguistic model of language acquisition. One of the primary criticisms of the behaviourist model is the concomitant that it is im likely for a child to be taught every sentence that he ever will have to use- and the behaviourist model doesnt count for an ability to create novel sentences. other criticism is the detail that parents dont use reinforcement consistently and in fact sometimes positively reinforce childrens errors (Owens,2008). Additionally, Chomsky (Owens, 2008) noted that adult speech is sufficient of errors and ungrammatic utterances and therefore would not provide a good model for children to learn from.As one of the earliest models of language acquisition, this model has been very influential in development of treatments. Our task as future clinicians is to invite out ideas from its strengths time keeping in mind the criticisms that have been set forward.The blurb theory of language acquisition chosen for this essay was social interaction theory. This model was developed in reply to the behavioural and linguistic theories of language acquisition and desegregates aspects of two of these. The social interaction theory suggests that language develops because of its social-communicative function. According to this theory, not that do we have an innate predisposition to language but many environmental factors also affect the course of language development (Bohannon Bonvillian,1993) the predisposition to language is seen as innate but the structure of language is not. In this model, the relationship between children and their linguistic en vironment is seen as a dynamic one in which both are drug-addicted on each other for efficient social communication and development of language skills (Bohannon Bonvillian, 1993). According to this model, social interaction is what conventionalises a childs language structure. fond interactionists believe that the child uses techniques to develop his or her language such as imitation or rote learning learning and the environment also adjusts itself to make haste language learning by the child as the child shows an increase ability to understand more(prenominal) complex language, the linguistic environment also increases in complexity (Bohannon Bonvillian,1993). The type of language that parents often use with children is referred to by social interactionists as Child Directed Speech (CDS). Child order speech includes communication techniques such as motherese, imitation, and scaffolding. This model suggests that children cue their parents to publish CDS and that the functio n of CDS is to activate the linguistic tendencies of the child (Bohannon Bonvillian,1993). According to this model, these techniques are apply by adults to slowly build the childs language bandage enabling adults and children to conk more effectually (Bohannon Bonvillian,1993).A strength of the social interactionist model is that because it worn on the behariourist and linguistic models it incorporates strengths from both. Much of the evidence for the social interactionist model comes from studies that guess at how caregiver-child interactions and CDS assist in language development. One of the big strengths of this model is the fact that it can account for the pragmatic aspects of language. According to Berko Gleason and Weintraub (1976), imitation and rote learning are utilize by children to learn things like social conventions (e.g. Thank-you) and Ninio and Snow(1999) (Bohannon Bonvillian, 1993) have shown that this model also accounts for the aspects of language that nee d to be learned socially. E.g. turn-taking, context, cultural conventions.Further evidence has been found for the effect of social interaction on a childs developing vocabulary in a determine by Tomasello and Farrar (1986)(Bohannon Bonvillian, 1993)who found that if a mother talks about the objects a child is meeting at the child tends to develop a larger and earlier initial vocabulary. Snow (1972, 1977, 1999)(Bohannon Bonvillian, 1993) has also found evidence for the fact that parents adjust their communication and use different communication techniques to dish out them air more effectively with their child.The social interactionist model has also attracted criticisms since its development. One of the most important things to top into account when looking at this model is the fact that because it is quite young many aspects of it have not been tested. Also link up to this is the criticism that social interactionists are seeing causation where there is only correlation (Boh annon Bonvillian,1993)- that it is impossible to tell from the studies being done whether a language delay is due to the parents lack of CDS or if the lack of CDS was a response of the parent to the language delay already present in the child (Bohannon Bonvillian,1993). A number of studies have also been carried out related to child directed speech and have found that CDS may not be as simplified as we believe it to be (Bohannon Bonvillian, 1993). In appendage to this, Shatz (1982)(Bohannon Bonvillian, 1993) argued that there is no mechanism specified for how CDS actually works to improve child language. These criticisms are important to take into account and place barely emphasis on the importance of having a evidence-based practice.The social interactionist model can both inform how an SLT approaches therapy and provide ides for practical application in clinical practice.This model suggests that children learn through the process of scaffolding. As a therapist this would su gest that therapy be approached by startle a child off with easier tasks and then gradually raising the difficulty level as he improves. The prescript of scaffolding could also be applied to choosing target sounds for phonological therapy. For example, starting with sounds that are developmentally earlier and easier to say. An example of a therapy that uses scaffolding and that is ofttimes used by therapists is minimal pair therapy (Williams et al., 2010). Another way to apply the social interactionist model in clinical practice would be to help the parents strengthen their use of child directed speech and show them how to incorporate effective language learning into their daily routines with the child. An example of a architectural plan that uses this type of technique is the Hanen approach. This is a therapy technique that emphasises the importance of parental conflict in a childs language development. The program places importance on both the treatment of children and the trai ning of parents to help them incorporate language learning more effectively into their everyday lives. (The Hanen Centre, 2011)The final model of language acquisition used for this essay was the information processing model. The information processing model is a cognitive view of language development which arose a languish with other interactionist approaches in the 1960s and 70s as a lot of research into the field of information was being carried out. As other aspects of human cognition such as memory and perception were coming to be seen as similar to the kit and caboodle of a computer, some theorists began exploring whether language development could be explained in a similar manner (Bohannon Bonvillian,1993). This model theorises that language is memorized in the same way as many other behaviours the nous receives stimuli, interprets it, stores it, and then can feed the appropriate output by retrieving the stored information (Bohannon Bonvillian,1993).According to the in formation-processing model, humans have an innate ability to learn language due to the presence of a mechanism called the Parallel Distributed Processor (PDP) (Bohannon Bonvillian,1993) however, like other interactionist models this theory also suggests that the environment plays an active role in language acquisition.According to this model, the couple distributed processor works by enabling children to learn language through example and reinforcement. The PDP is a network of nodes and paths modelled on the neural tracks in the brain. The nodes are connected by many levels and layers of pathways. The information processing model is sometimes called the connectionist model for this reason. The nodes receive excitant from pathways coming from many other nodes and if fair to middling pathways stimulate a node the node will activate and a certain output will be generated.One of the most well-known aspects of the information processing theory is the Competition Model (Bohannon Bo nvillian, 1993) which attempts to explain how precisely these pathways and nodes generate linguistic output. According to this, a child has multiple possible forms of a word in their head (e.g. agone tense of or ) which compete to represent a meaning. The form that ends up being used is determined by the number of nodes and pathways that are activated for each form.For example, a child learning to say the past tense of may not know yet whether the proper form is or . When the child decides to say this word, the pathways for both and would be activated as possible outputs. If the child chooses to say the correct option that pathway will be strengthened and the pathway for the chimerical response will be weakened. If the child chooses to say the incorrect option () and discovers that this is incorrect, that pathway will be slightly downgraded and the other pathway that should have been activated, , will be slightly strengthened. Eventually, over time and through experience the childs PDP system will agree on the true form of a word and produce a consistent, correct output. This is the manner in which children are seen to learn words and grammar.Over the years this model has stash away evidence both in favour of it and against it. A strength of this model is that it accounts for many aspects of language learning such as how children learn oftentimes used forms more quickly than other less frequently used forms (Bohannon Bonvillian, 1993). It also accounts for both the appearance of overregularisation errors and their disappearance. Additionally, in a study by Meyer and Schwaneveldt (1971) (Bohannon Bonvillian, 1993), it was found that when a word is used it primes (subconsciously makes us think of) other related words therefore there essential be some spreading activation in the language processor. This provides evidence for the existence of matching pathways. Much of the other supporting evidence comes from the experimental computerised model of t he PDP. In 1987, Rummelhart and McClelland (Bohannon Bonvillian, 1993) ran simulations on this model and found that in the case of simulating past-tense learning and business they got very similar learning patterns to those found in children. Additionally, when part of the language network of the PDP was shut down to simulate brain damage, the resulting performance was very similar to the deficits found in brain-damaged human patients (Bohannon Bonvillian, 1993). Studies by Elman (1993)(Bohannon Bonvillian, 1993) using the same computerised model have shown that the learning ability of the system extends beyond words and can also account for the development of the syntactic system if abounding examples of adult language are given.While this model has many strengths, there are also significant weaknesses. First of all, while it can account for the formation of language, it does not account for the acquisition of semantics. Additionally, as admitted by Rohde and Plaut (1999)(Boha nnon Bonvillian, 1993), it doesnt take into account the social aspect of conversation, in other words, how we decipher language in relation to the social situation and how that affects what we say. Another criticism of the model of the PDP mechanism is that while it does well with information that is presented all at once (e.g. a picture), it has trouble with serial processing (Bohannon Bonvillian, 1993). This poses a problem since language is serial by nature. Another common criticism of this theory is that information processing theorists make too much of the superficial similarities between the brain and the proposed PDP when there are actually many differences (Bohannon Bonvillian, 1993).A strength of this model is the fact that it may give insight into how to approach the treatment of problems relating to the grammatical structures of language. For example, the PDP system showed it could learn proper grammar through bombardment. Therefore, according to this model, bombardmen t will allow the child to internalise the desired structure because the input pathways will be provided with enough adult-level examples to form the correct pathway. As an application in therapy then, this suggests that the SLT could choose exercises in which the child hears the correct structure over and over again. The PDP model also suggests that each structure must be worked on separately in treatment because they all use different pathways. For example, if past tense is the problem then regular past tense must be worked on and once that structure overgeneralises then the exceptions should be targeted. As an application in clinical practice then, if the child is trying to acquire regular and irregular past tense, the SLT should start with treatment of the regular past tense, wait for that pattern to overgeneralise and then work on individualistic irregular past tense verbs.Both imitation and repetition are also implied as practical applications of this model in clinical practic e. By having the child imitate the proper form it is suggested that both the proper input and output pathways will be activated, therefore helping the child to solidify the correct one more quickly. Similarly, by eliciting the child to repeat the proper form this model implies that the correct language pathway to solidify more quickly. In a study by Whitehurst and Novak (1973) imitation was shown to be effective in helping children solidify specific rules in their own speech and the techniques of bombardment and repetition were used as part of the treatment in a study by Seeff-Gabriel et al.(2012) which had success in a child learning to generalise the regular past tense.It is important to note that while these treatments may be effective in some cases, as antecedently mentioned, there is criticism for the information- processing model. It is our duty as future clinicians to look further into the research and study the effectiveness of these approaches before spending long periods o f time on them with patients.All of the theories discussed here have strengths and weaknesses and all of them have implications for clinical practice. Depending on which theory an SLT is influenced by, the therapeutic approach will be different. One of the keys to being a good speech and language therapist is the ability to look at these different models and see how their strengths can be applied to create effective therapy for the client. In addition to this however, it should be kept in mind that these are only theories of language acquisition and that while we should be very aware of the theoretical underpinnings that influence the therapy and techniques we use, our aim should not be to create a practice based solely on theories. Our aim needs to be to create an evidence-based practice guided by the continuing advances in theories and current research.
