In this paper we provide normative data along multiple cognitive and affective variable dimensions for a set of 110 sounds, including living and manmade stimuli. Environmental sounds are being increasingly utilized as stimuli in the cognitive, neuropsychological and neuroimaging fields, yet there is no comprehensive set of normative information for these type of stimuli available for use across these experimental domains. Experiment 1 collected data from 162 participants in an on-line questionnaire, which included measures of identification and categorization as well as cognitive and affective variables. A subsequent experiment collected response times to these sounds. Sounds were normalized to the same length (1 second) in order to maximize usage across multiple paradigms and experimental fields. These sounds can be freely downloaded for use, and all response data have also been made available in order that researchers can choose one or many of the cognitive and affective dimensions along which they would like to control their stimuli. Our hope is that the availability of such information will assist researchers in the fields of cognitive and clinical psychology and the neuroimaging community in choosing well-controlled environmental sound stimuli, and allow comparison across multiple studies.
本文提供了一套 110 种声音（包括生物和人造刺激物）的认知和情感变量的规范数据。环境声音在认知、神经心理学和神经影像学领域中被越来越多地用作刺激物，但这些类型的刺激物在这些实验领域中没有全面的规范信息可供使用。实验 1 通过在线问卷收集了 162 名参与者的数据，其中包括识别和分类以及认知和情感变量的测量。随后的实验收集了对这些声音的反应时间。为了最大限度地在多个范式和实验领域中使用，声音被归一化为相同的长度（1 秒）。这些声音可以免费下载使用，并且还提供了所有的反应数据，以便研究人员可以选择他们希望控制其刺激物的一个或多个认知和情感维度。我们希望提供这些信息将有助于认知和临床心理学领域以及神经影像学社区的研究人员选择经过良好控制的环境声音刺激物，并允许在多个研究中进行比较。
