Performance of Language-Coordinated Collective Systems: A Study of Wine Recognition and Description

View Article: PubMed Central - PubMed

ABSTRACT

Most of our perceptions of and engagements with the world are shaped by our immersion in social interactions, cultural traditions, tools and linguistic categories. In this study we experimentally investigate the impact of two types of language-based coordination on the recognition and description of complex sensory stimuli: that of red wine. Participants were asked to taste, remember and successively recognize samples of wines within a larger set in a two-by-two experimental design: (1) either individually or in pairs, and (2) with or without the support of a sommelier card—a cultural linguistic tool designed for wine description. Both effectiveness of recognition and the kinds of errors in the four conditions were analyzed. While our experimental manipulations did not impact recognition accuracy, bias-variance decomposition of error revealed non-trivial differences in how participants solved the task. Pairs generally displayed reduced bias and increased variance compared to individuals, however the variance dropped significantly when they used the sommelier card. The effect of sommelier card reducing the variance was observed only in pairs, individuals did not seem to benefit from the cultural linguistic tool. Analysis of descriptions generated with the aid of sommelier cards shows that pairs were more coherent and discriminative than individuals. The findings are discussed in terms of global properties and dynamics of collective systems when constrained by different types of cultural practices.

Figure 2: Number of wines recognized and placed correctly in each condition.

Mentions: It is important to notice that even though the average scores in the 4 conditions do not differ, there is a significant difference in the overall scores distribution (Figure 2). For the conditions with sommelier cards, especially for pairs with sommelier card, distribution of scores gravitates toward the middle. Those differences between conditions were found significant by Fisher's exact test comparing numbers of medium scores (1 or 2 correct recognitions) and numbers of extreme scores (0 or 3) (p = 0.0002).
