The Relationship

Eye-tracking method has been increasingly used for studying food consumer behavior in the last few years because of its objectivity. This study applied eye-tracking technique to investigate the food choice behavior of Vietnamese consumers: from gazing, and expected liking to perceived liking. The Tobii T60 eye-tracker was used for recording and analysing the gazing behavior of consumers. Four traditional mooncakes with different ingredients were tested by 70 Vietnamese participants: 1) Product pictures were shown on a screen. Participants had to choose the product they liked the most. During this process, gazing behavior was recorded with an eye-tracker; 2) Product samples were served for tasting. Participants had to rated their perceived liking using conventional 9-point hedonic scale.Results showed that the investigated gazing behavior parameters (fixation count, fixation duration, visit duration and visit count) correlated significantly in a positive way with the “wanting to try” choice. Moreover, this choice is in compliance with “perceived liking”. Results have been discussed considering the relationship between eye-movements, decision making process and choosing behavior. This study applied a new objective technique to study food consumer behavior. Moreover, it opens preliminarily a multiple-tool approach in improving the understanding of consumers’ food choice perception and behavior.

Purpose The primary purpose of this study was to explore the audiovisual speech perception strategies.80.23.47 adopted by normal-hearing and deaf people in processing familiar and unfamiliar languages. Our primary hypothesis was that they would adopt different perception strategies due to different sensory experiences at an early age, limitations of the physical device, and the developmental gap of language, and others. Method Thirty normal-hearing adults and 33 prelingually deaf adults participated in the study. They were asked to perform judgment and listening tasks while watching videos of a Uygur–Mandarin bilingual speaker in a familiar language (Standard Chinese) or an unfamiliar language (Modern Uygur) while their eye movements were recorded by eye-tracking technology. Results Task had a slight influence on the distribution of selective attention, whereas subject and language had significant influences. To be specific, the normal-hearing and the d10eaf participants mainly gazed at the speaker's eyes and mouth, respectively, in the experiment; moreover, while the normal-hearing participants had to stare longer at the speaker's mouth when they confronted with the unfamiliar language Modern Uygur, the deaf participant did not change their attention allocation pattern when perceiving the two languages. Conclusions Normal-hearing and deaf adults adopt different audiovisual speech perception strategies: Normal-hearing adults mainly look at the eyes, and deaf adults mainly look at the mouth. Additionally, language and task can also modulate the speech perception strategy.

Spoken Language Comprehension

A visual world eye-tracking study investigated the activation and persistence of implicit causality information in spoken language comprehension. We showed that people infer the implicit causality of verbs as soon as they encounter such verbs in discourse, as is predicted by proponents of the immediate focusing account ( Greene & McKoon, 1995 ; Koornneef & Van Berkum, 2006 ; Van Berkum, Koornneef, Otten, & Nieuwland, 2007 ). Interestingly, we observed activation of implicit causality information even before people encountered the causal conjunction. However, while implicit causality information was persistent as the discourse unfolded, it did not have a privileged role as a focusing cue immediately at the ambiguous pronoun when people were resolving its antecedent. Instead, our study indicated that implicit causality does not affect all referents to the same extent, rather it interacts with other cues in the discourse, especially when one of the referents is already prominently in focus.
