Slips of tongue in students speech at bilingual Islamic high school

This study focuses on the speech error production under the psycholinguistics study. It aimed to investigate the speech error experienced by the students of MBI Amanatul Ummah Mojokerto in which the students are living in bilingual environment. The data are analyzed on the basic types of slip of the tongue and to identify possible factors causing the speech error production. Based on the findings, the researcher found three from seven kinds of slip of the tongue which were produced by the students in classroom presentation. Those types were transpositions, blends, and haplologies. From that case, the most dominant type was haplologies. In addition, there were several possible factors which caused the speech error production: cognitive, psychological or affective, and social reason. Thus, this study found that all of reasons became the factors of the students' speech error. In the same way, psychological or affective reason --resulted from the state of being nervous-- became the dominant reason. Moreover, the researcher also tried to explore the effects which were acquired by the hearer after hearing the speech error production. Most of students argued that speech error produced brought funny case to the hearer. Therefore, it is recommended for the future study to apply another theory to investigate the production of the speech error in any context of speech productions
