Bakgrund: Dikotiska tester kan användas som del i testbatteriet för utredning av hörseluppfattningsstörning (APD, eng. auditory processing disorder) samt vid differentialdiagnostisering. I Sverige har dikotiska tester använts i studier där försökspersonerna varit 11 år eller äldre. Utanför Sverige har studier dock gjorts på barn från 5 år och uppåt. Syfte: Syftet med denna undersökning var att ta fram ett normalmaterial avseende dikotiska tester för elever i årskurs 1, 2, 3 respektive 4 i grundskolan. Metod: Dikotiska tester har utförts vid två grundskolor, på totalt 53 elever i årskurs 1-4. Testmaterialet bestod av siffror, stavelser samt meningar, vilket rapporterats med riktad rapportering. Siffror och stavelser har även återgivits med fri rapportering. Resultat: Generellt fick majoriteten flest rätt på höger öra. Störst skillnad i resultat sågs mellan årskurs 1 och 4. En tendens till minskad lateraliseringseffekt kunde ses med ökad ålder.   Slutsatser: Då lateraliseringsindex visade positivt värde hos årskurserna 1, 2 och 4, vid deltesten med stavelser och meningar, kunde slutsatsen dras att majoriteten av dessa barn uppvisade right-ear-advantage (REA).

The topic of this study is left-handedness as a phenomenon in violin playing and classical violin pedagogy. The aim of the study is to investigate what kind of knowledge and approaches are crucial for taking left-handedness into account when teaching left-handed violinists in the normatively right-handed violin pedagogy. The body of knowledge arises from literature on hemispheric lateralization, left-handedness, attributes of violin playing, and earlier studies on hand-preference and musical performance, hemispheric adaptations to musical training, and children’s conceptions of left and right. A background-study was carried out on left-handedness in guitar playing. The study employs abductive reasoning, has an auto-ethnographic thread and draws on the hermeneutical epistemology. The theoretical framework rests on the cultural-psychological perspective on music education. The data was collected in two parts using qualitative ethnography-inspired methods. First qualitative thematic interview was used for gathering strategically sampled data from expert respondents on violin playing, pedagogy and violin-making. Secondly non-participant observation and follow-up interview was used for examining a beginner violin lesson. The findings of the study suggest that violin pedagogues need knowledge of the lateralization effects on violin playing and methodological understanding for pupils’ handedness and maturity of motor development. The data suggests that left-handedness is not a disadvantage in violin playing when provided with education that recognizes it. Reversed violin playing is considered as an alternative for strongly left-handed pupils. The data shows that violin education needs open discussion on left-handedness in terms of prejudices in orchestras, and raised awareness on the availability of left-handed instruments.
