Researchers across domains of behavior analysis agree that complexities of language acquisition can be defined by the degree to which an individual acquires language relations in the absence of direct training. In a series of studies, I examined the role of voluntary echoic responses on the onset of bidirectional naming (BiN) and the implications of the naming continuum, defined by accuracy of listener and speaker responses for familiar stimuli, on the emergence of untrained, language relations. Using a group descriptive analysis, I tested the correlations between storybook naming experiences and accuracy of listener (selection) and speaker (tact) responses across 24 toddlers, aged 20- to 37-months-old. During the naming experience, I measured voluntary production of the target stimulus (saying the target word). During the naming probe, I measured accuracy of untaught listener and speaker responses. While there were not significant associations between voluntarily saying the target stimulus and the accuracy of listener/speaker responses and voluntary responses remained low across 3 naming experiences, there were significant associations among accuracy of listener/speaker responses across the 3 experiences. Listener responses significantly increased across the three experiences, suggesting the emergence of unidirectional naming (UniN); however, speaker responses remained low. In Experiment II, I tested the effects of echoic clarity (phonemic responses that each participant demonstrated) on accuracy of untaught listener/speaker responses using storybook naming experiences. Data remained consistent in suggesting that UniN was present, but echoic clarity was not functionally related to measures of BiN. In Experiment III, I tested the effects of temporal proximity of visual and auditory stimuli on voluntary echoics and accuracy of listener/speaker responses using Successive Naming Experiences with Novel Stimuli (SNENS). This consisted of presenting auditory and visual stimuli simultaneously or with a one-second delay between the visual and auditory stimuli. Data remained consistent across participants in showing that the accuracy of listener/speaker responses was not dramatically affected by temporal proximity of visual and auditory stimuli. Serendipitous findings of this experiment suggested that the joining of listener and speaker responses may be required for acquisition of more complex derived relations. I conducted Experiment IV to address the unanticipated findings of the pilot study, by testing if a functional relation exists between the naming continuum and the emergence of other arbitrarily applicable derived relations (AAR). Four of the 6 participants demonstrated mastery of mutual and combinatorial entailment relations following increased degrees of BiN, while 2 of the participants demonstrated increases in combinatorial entailment relations. Results suggested a functional relation exists between the accuracy of untaught listener/speaker responses for word-object relations and the emergence of other AAR. I discuss these findings with regards to the essential stimulus control for untaught language relations as a history of reinforcement for correspondence.

Two testing conditions (immediate and delayed) were used to test for the presence of imitation and emulation in typically developing and developmentally delayed children, including children with autism spectrum disorder, ranging in age from 2.8-years old and 4.0-years old, in two experiments, Experiment I (n=20), Experiment II (n=30). Using a mixed within-between design, I compared the performance of the two groups across various tasks in two testing conditions and analyzed their performance. The participants were selected because they fit the criteria of 1) being between the age of 2.5 and 4 years of age at the onset of the study, 2) had gross motor and generalized imitation in repertoire, and 3) observational learning was present. The independent variable was the test interval in both experiments across both testing conditions, immediate and delayed. The dependent variables were the unconsequated responses during the test interval (Experiment I and II). The embedded dependent variable in Experiment II was the number of 5s intervals participants interacted with a puzzle box in the free play setting. Responses were defined as imitation (copy the specific actions with point-to-point correspondence), or emulation (bring about the model’s goal by the observer’s own methods and means, no point-to-point correspondence but same end result). In the first experiment I found that although typically developing preschoolers often imitate in the short term, they were more likely to emulate in the long term when not shown again how to use the items. In contrast the participants with autism spectrum disorder were more likely to imitate across both testing conditions. My findings support evidence that typically developing children naturally shift from imitation to emulation and that children are in fact emulators in contrast to research that suggests otherwise. For those children with autism, Experiment I, supports evidence that they are potentially missing a developmental cusp (emulation). Experiment II sought to replicate the findings in Experiment I and differed in that 1) more tasks were added, 2) more participants were used, and 2) a free play observation session was added. The results from Experiment II supported the results from Experiment I, in that, all participants (typically developing and those with autism) were more likely to imitate in the short-term immediate testing condition; however, typically developing children naturally shifted to an emulative response given a delay, whereas, those children with autism continued to emit imitative behaviors given a delay, signifying that children with autism are missing the developmental cusp of emulation. The findings support the notion that emulation is a developmental cusp and that children with autism often are missing this developmental cusp.

M.Ed. / The socio-political climate in South-Africa has led to an increase in the number of children experiencing anxiety-related symptoms. Children are observant and notice how their parents react and discuss with other adults the violence and uncontrollable crime rate that exists in our society at present. Society generally views childhood as a naturally happy time, free of responsibilities and worries. But the implication that children are somehow protected from the emotional effects of traumatic events is not true. Children are, in fact, as susceptible to trauma as adults. Many children have experienced incredible trauma first hand and these traumatic events can have a negative effect on the child's self concept and future functioning. Mother problem arising from the insecurity of the socio-political climate is that parents tend to feel that they have to take greater safety precautions, thus children are lacking opportunities for developing independence. Other stress aspects are the changes in family structures. One out of every three children will experience divorce, and will have to cope with the stress of reconstituted families. Not only is there stress involved in the process of divorce, but prior to the divorce conditions within the home are unbearable tense and full of conflict. Children in the South - African townships are often left in the care of extended families due to the fact that their parents may be working far from where they live and go to school. Because of the complexities and breakdown of family life, these children are often forced to get on with their lives and growing up on their own, with no or little family support. It is clear that our children of today often find themselves in positions that they are not developmentally and emotionally equipped to handle, and the instinct of survival is often what they rely on. The South African society consists of a set of complex and often polarised systems, each with its own difficulties. The need for intervention and therapy is great, but the resources are limited. Psychotherapy with a professional play therapist is just not a viable solution for many children. Not only is there a limit to the professional resources available, but a lot of parents see it as a waste of time and the financial cost can be crippling. The situational access is another problem that needs to be addressed. Many children are simply not in a physical position to gain access to therapy. It becomes clear every day that in South Africa, the Western view of individualised and specialised play therapy for children is simply not feasible in many instances. The objective of this research project is to describe the therapeutic process in order to establish certain guidelines regarding therapy with traumatized toddlers. The efficiency of this process will also be discussed. The design of this research project compelled a qualitative research strategy, where the researcher in this study is also the therapist. A participating research process is thus of importance in this project. This research project looks at the process and the implications of short term therapy, especially Narrative Therapy with toddlers between the ages of four to seven years. The project describes the therapy process of co-constructing new and preferred narratives with three clients by challenging dominant discourses of violence, death , loss and trauma. The results of the therapeutic process as well as the shortages and recommendations conconclude this research project.

In die konteks van hierdie studie word daar deurlopend van die manlike vorm gebruik gemaak om na die kleuter te verwys, ten einde 'n lomp stelwyse te voorkom. Die vroulike vorm sou ook daarmee veronderstel en ingesluit kon word. Die vroulike vorm word gebruik wanneer daar na die moeder verwys word. / Merkbare verandering word soms in die kleuter se gedrag, emosies en verhoudings na die geboorte van `n baba waargeneem. Die doel van die kwalitatiewe studie was om die moeder se persepsie, belewenis en hantering van hierdie aanpassingsprobleme van die kleuter te verken. Semi-gestruktureerde onderhoude is met nege moeders gevoer. Uit die studie het dit duidelik geword dat onkunde ten opsigte van die ontwikkelingsfase van die kleuter, asook die aanpassingsprobleme aanleiding tot foutiewe persepsies by die moeder gegee het. Hierdie foutiewe persepsies het `n negatiewe invloed op die moeder se belewenis en hantering van die aanpassingsprobleme gehad. Die navorser het tot die gevolgtrekking gekom dat moeders betrek moet word vir ouerleiding wanneer aanpassingsprobleme by die kleuter aangemeld word. Verskeie aanbevelings wat van waarde kan wees tydens ouerleiding aan moeders van kleuters is deur die navorser gemaak. / The birth of a sibling often results in a toddler displaying changes in behaviour, emotions and relationships. The aim of this qualitative study was to explore the mother's perception, experiences, as well as coping strategies of the toddler's adaptation problems, following the birth of a sibling. Semi-structured interviews were conducted with nine mothers. The study revealed that the mother's lack of knowledge and understanding of the developmental phase of the toddler, as well as the adaptation problems, manifested in misconceptions. These misconceptions affected her experiences of the adaptation problems, as well as how she managed it. The researcher concluded that mothers should be referred for parental guidance when adaptation problems are reported. Various recommendations to be used within parental guidance have been made. / Social Work / M.Diac. (Spelterapie-Rigting)
