作者调查了48只家养狗（Canis familiaris）的偏侧程度和噪音恐惧症之间的关系，方法是通过重放和问卷调查来衡量爪子对抓食物的偏好，并将其与对雷暴和烟花声音的反应联系起来。没有明显爪子偏好的狗对声音的反应明显比左爪或右爪偏好的狗更强烈。因此，强烈的反应性与较弱的大脑侧化强度有关。作者注意到他们的发现与极度焦虑的人所表现出的较弱的手偏好之间的相似性，并提出可能涉及的神经机制。
The authors investigated the relationship between degree of lateralization and noise phobia in 48 domestic dogs (Canis familiaris) by scoring paw preference to hold a food object and relating it to reactivity to the sounds of thunderstorms and fireworks, measured by playback and a questionnaire. The dogs without a significant paw preference were significantly more reactive to the sounds than the dogs with either a left-paw or right-paw preference. Intense reactivity, therefore, is associated with a weaker strength of cerebral lateralization. The authors note the similarity between their finding and the weaker hand preferences shown in humans suffering extreme levels of anxiety and suggest neural mechanisms that may be involved.
