The aim of this research was to study the effectiveness of teaching with the simultaneous prompting in teaching students with intellectual disabilities attending the vocational education center and their ability to fold towels. Multiple baseline models with inter-subject probe stage, which is one of the single-subject research methods, has been used. The subjects of the research are three students, one female and two males, between the ages of 16-18. The dependent variable of the study was determined as the ability to fold the towel and the independent variable as the teaching with the simultaneous prompting using the physical prompt as a model + verbal prompt and error correction. In the study, inter-observer reliability and procedural reliability data were collected. Graphical analysis was used to determine the effectiveness of teaching with the simultaneous prompting. According to the findings obtained from the research, simultaneous prompting teaching is effective in teaching students with intellectual disabilities the ability to fold towels. It has been observed that the skill of folding towels into shapes continues to last two, three, and four weeks after the end of the education and that the subjects can generalize the skill in different types of towels.

Abstract The aim of this study was to clarify whether fingerspelling provides a sophisticated mechanism that promotes the development of detailed orthographic knowledge for deaf individuals even in the absence of paralleling phonological knowledge. An intervention program comprised of various procedures chaining between fingerspelled sequences; their written correlates and meaning were administered in a multiple probe single-subject research design across semantic categories to four children with severe to profound prelingual hearing loss (age 4.2–6 years). Results demonstrate the occurrence of rapid orthographic learning during intervention and reliable retention of it in maintenance checks, despite the participants’ insufficiently developed phonological skills. Observations of the participants’ behavior further suggest fingerspelling to function as an effective mediator in the initial development of robust detailed orthographic lexicon. Analyzes also indicate that “learning through action” and “relevance to the task” provide two key factors in relation to the promotion of orthographic learning, with their absence creating an obvious vacuum in this regard. Insights from the study are discussed with reference to their implication for the development of learning materials and learning environments for prelingually deaf and other novice learners.

The physiological subscale of the Revised Children's Manifest Anxiety Scale was examined using a matched single-subject research design. As predicted, a high scorer on the physiological subscale had a significantly higher resting EMG and did not significantly recover as did the low scorer on the physiological subscale on EMG. Contradictory findings were observed on skin temperature measures. Findings are discussed relative to the scope and shortcomings of the investigation, and directions for research are suggested.
