判断一群人的规模是一项日常任务，许多决策都是以此为基础的。在本研究中，我们调查了对不同人群大小的判断是否取决于他们是通过听觉通道、通过视觉通道还是通过听觉和视觉通道呈现。在虚拟环境中向健康参与者呈现不同大小的类人群体（从 8 到 128 人）。他们必须判断每组中是否有很多人，并用主观痛苦单位来评估他们对刺激的不适程度。我们的 96 名和 128 名虚拟人组无论感官表现如何，都被视为群体。感官呈现影响参与者对虚拟人群体规模的判断，范围为8到48人。此外，虽然听觉条件下的数量判断随着群体规模的增加而线性增加，但参与者在另外两种感官条件下以对数方式判断人数。这些结果表明，在现实环境中基于听觉信息的数量判断通常可能涉及隐式算术。尽管我们的参与者并不害怕人群，但我们的研究结果对于基于虚拟现实的多种疾病治疗领域很有意义，因为它们表明，对于害怕人群的患者来说，数量判断可能会以特定感觉的方式改变。
Judging the size of a group of people is an everyday task, on which many decisions are based. In the present study, we investigated whether judgment of size of different groups of people depended on whether they were presented through the auditory channel, through the visual channel, or through both auditory and visual channels. Groups of humanoids of different sizes (from 8 to 128) were presented within a virtual environment to healthy participants. They had to judge whether there was a lot of people in each group and rate their discomfort in relation to the stimuli with Subjective Units of Distress. Our groups of 96 and 128 virtual humans were judged as crowds regardless of their sensory presentation. The sensory presentation influenced participants’ judgment of virtual human group size ranging from 8 to 48. Moreover, while the quantity judgments in the auditory condition increased linearly with the group size, participants judged the quantity of people in a logarithmic manner in the two other sensory conditions. These results suggest that quantity judgment based on auditory information in a realistic context may often involve implicit arithmetic. Even though our participants were not phobic of crowds, our findings are of interest for the field of virtual reality-based therapy for diverse disorders because they indicate that quantity judgment can potentially be altered in a sensory-specific manner in patients with fear of crowds.
