Abstract

ABSTRACT Viewing sets of food products is common in consumer environments. Previous research on visual perception suggests the phenomena of global judgements (or summary statistical representation), which means that people often extract summary statistical information of multiple objects (e.g., average size, hue) at a glance. Consumers may form summary statistical representations of food products. Despite the growing number of studies on the cognitive processing of food products, global judgements of caloric information and how differences in age influence the global judgements remain unexplored. Here, we aimed to reveal global judgements of caloric perception in younger and older adults. Across two studies, participants (adults in Study 1 and younger and older adults in Study 2) viewed food image sets (single, two, four, or six images) and estimated the average caloric counts. The results revealed that the participants could accurately estimate the average caloric counts to some extent at two set sizes. Moreover, the participants were less able to extract global judgements of caloric information at four and six set sizes. Overall, our findings reveal limited cognitive processing for assessing average caloric content, and age differences modulate the estimation accuracy.

年轻人和老年人热量信息的整体判断

在消费者环境中，观看食品是很常见的。以往对视觉感知的研究提出了全局判断(global judgment)现象，即汇总统计表征(summary statistical representation)，即人们往往一眼就能提取出多个物体的汇总统计信息(如平均大小、色调等)。消费者可以对食品进行汇总统计。尽管对食品认知加工的研究越来越多，但热量信息的整体判断以及年龄差异如何影响整体判断仍未得到探索。在这里，我们的目的是揭示年轻人和老年人对热量感知的整体判断。在两项研究中，参与者(研究1中的成年人和研究2中的年轻人和老年人)观看食物图像集(单个，两个，四个或六个图像)并估计平均卡路里计数。结果显示，参与者可以在一定程度上准确地估计两组尺寸的平均热量计数。此外，参与者在四组和六组尺寸下提取热量信息的总体判断能力较差。总的来说，我们的研究结果揭示了评估平均热量含量的有限认知加工，年龄差异调节了估计的准确性。

期刊介绍： Visual Cognition publishes new empirical research that increases theoretical understanding of human visual cognition. Studies may be concerned with any aspect of visual cognition such as object, face, and scene recognition; visual attention and search; short-term and long-term visual memory; visual word recognition and reading; eye movement control and active vision; and visual imagery. The journal is devoted to research at the interface of visual perception and cognition and does not typically publish papers in areas of perception or psychophysics that are covered by the many publication outlets for those topics.
