Social attitudes and reactions towards people who stutter (PWS) are generally examined through scales. The purpose of this study is to compare the attitudes and behaviors of Turkish and non-Turkish individuals in their interactions with PWS in an experimental condition. The participants were two PWS and 16 adults as interaction partners, including eight Turkish and eight non-Turkish individuals. In the experiment, each interaction partner engaged in a conversation with PWS on spontaneous themes. Four raters scored the attitudes of the interactors by watching the recorded videos via a questionnaire consisting of 49 antonym adjectives. Two raters calculated the interactive behaviors of the interaction partners. Based on the qualities with an agreement rate over .7 according to the reliability findings, the groups were compared with independent samples t-test. In the behavioral sense, the Turkish group exhibited significantly more 'sentence completion' and 'asking consecutive questions' behaviors compared to the non-Turkish group. In terms of interaction attitudes, the Turkish group received significantly higher scores in responding in the first syllable, completing the statement, being serious and anxious. In comparison to the Turkish group, the non-Turkish group received significantly higher scores in using gestures/facial expressions and being empathetic, warm, positive, sincere, sympathetic, and open.
