En studie av lexikon och gestproduktion hos barn med respektive utan språkstörning genom utförandet av ordförrådstestet PiNG

Sammanfattning: The aim of the present study was to examine receptive and expressive lexicon, as well as gesture production among children with and without developmental language disorder (DLD), Using the Swedish translation of the Picture Naming Game (PiNG). The parental evaluation Swedish Communicative Development Inventory III (SCDI III) was used to determine whether the results from PiNG and SCDI III were consistent. In this study, 10 children with DLD (study group) and 11 age-matched children with typical language development (control group) between 52 and 70 months of age participated. The participants were tested with PiNG, which is a test that examines reception and production of single nouns, verbs, adjectives, adverbs and prepositions. The guardians then completed SCDI III, which contains questions about the language abilities of the child. Gesture production in the form of deictic, iconic and conventional gestures was examined in conjunction with the use of PiNG. The results showed lower results for the study group on PiNG and SCDI III in comparison with the control group. The study group displayed a higher number of gestures than the control group, and in the former group, the use of gestures was positively correlated with the results from PiNG. In the study group, iconic gestures were used to compensate for language difficulties. The results from PiNG and SCDI III were not consistent. The age of the participants problably did not affect any results. The results from the present study indicate that PiNG may be useful when examining lexicon and gesture production among children with DLD. Both groups achieved high results on PiNG which may have affected the use of gestures and also possible correlations. For future studies, it is therefore recommended to apply PiNG on a group of younger children with DLD.
