Dyads composed of unacquainted females (n=82) watched a cartoon while consuming salty aperitif snacks. The Affective Communication Test was used to measure nonverbal expressiveness. Computing intraclass correlation coefficients, the extent to which participants within dyads matched each other's food intake was analyzed. Food intake matched highly for dyads with two expressive individuals and moderately for dyads with one expressive participant. For dyads with two unexpressive participants, there was no evidence for matching behavior. Highly expressive people seem to be able to synchronize with others and thereby allow for close matching. This is the first study to show an influence of personality on matching consumption behavior.
由不熟悉的女性组成的二人组（n=82）在观看卡通片的同时食用咸味开胃小吃。使用情感交流测试来衡量非语言表达能力。通过计算组内相关系数，分析了参与者在多大程度上相互匹配他们的食物摄入量。对于有两个表达能力强的个体的二人组，食物摄入量高度匹配；对于有一个表达能力强的参与者的二人组，食物摄入量中度匹配。对于有两个不表达的参与者的二人组，没有证据表明存在匹配行为。高表达能力的人似乎能够与他人同步，从而实现密切匹配。这是第一项表明个性对匹配消费行为有影响的研究。
