This study investigated a possible role for identification in the decline in flavor pleasantness with age.
Two hundred sixty-four individuals aged from 16 to 85 years tasted 6 flavored drinks of varying identity and ease of identification, and rated each on pleasantness, a range of other characteristics and identified all flavors.
Using regression, firstly, pleasantness was inversely associated with age (β = -0.22, p < .01). Secondly, the decline in pleasantness with age was associated with poorer identification (β = 0.30, p < .01), lower perceptions of sweetness (β = 0.01, p < .01), lower strength of flavor (β = 0.00, p = .02), lower familiarity (β = 0.01, p < .01), and a lower frequency of usual drink consumption (β = 0.04, p < .01). Thirdly, improved identification with age was associated with increased drink familiarity (β =< 0.01, p < .01), coloration compared with no color (β = <0.06, p < .01), and correct compared with incorrect coloration (β = <0.27, p < .01).
These findings demonstrate a clear role for identification in the decline in flavor pleasantness with age. These findings thus provide clear evidence for a cognitive and perceptual element to these hedonic processes. Our findings suggest that likings for flavors in older individuals may be increased/maintained through the use of improved visual cues, easily recognizable foods, and/or identity labels.
本研究调查了识别在随着年龄增长风味愉悦度下降过程中可能发挥的作用。
264名年龄在16至85岁之间的个体品尝了6种具有不同辨识度和识别难易程度的调味饮料,并对每种饮料的愉悦度、一系列其他特征进行评分,同时识别所有风味。
通过回归分析,首先,愉悦度与年龄呈负相关(β = -0.22,p < .01)。其次,随着年龄增长愉悦度下降与识别能力较差(β = 0.30,p < .01)、对甜度的感知较低(β = 0.01,p < .01)、风味强度较低(β = 0.00,p = .02)、熟悉度较低(β = 0.01,p < .01)以及日常饮料消费频率较低(β = 0.04,p < .01)有关。第三,随着年龄增长识别能力的提高与饮料熟悉度增加(β =< 0.01,p < .01)、有颜色与无颜色相比(β = <0.06,p < .01)以及颜色正确与颜色错误相比(β = <0.27,p < .01)有关。
这些发现表明识别在随着年龄增长风味愉悦度下降过程中起着明确作用。因此,这些发现为这些享乐过程中的认知和感知因素提供了明确证据。我们的研究结果表明,通过使用改进的视觉线索、易于识别的食物和/或身份标签,可能会增加/维持老年人对风味的喜好。
