Social relationship-dependent neural response to speech in dogs

In humans, social relationship with the speaker affects neural processing of speech, as exemplified by children’s auditory and reward responses to their mother's utterances. Family dogs show human analogue attachment behavior towards the owner, and neuroimaging revealed auditory cortex and rewa...

Description
Summary:In humans, social relationship with the speaker affects neural processing of speech, as exemplified by children’s auditory and reward responses to their mother's utterances. Family dogs show human analogue attachment behavior towards the owner, and neuroimaging revealed auditory cortex and reward center sensitivity to verbal praises in dog brains. Combining behavioral and non-invasive fMRI data, we investigated the effect of dogs’ social relationship with the speaker on speech processing. Dogs listened to praising and neutral speech from their owners and a control person. We found positive correlation between dogs’ behaviorally measured attachment scores towards their owners and neural activity increase for the owner’s voice in the caudate nucleus; and activity increase in the secondary auditory caudal ectosylvian gyrus and the caudate nucleus for the owner’s praise. Through identifying social relationship-dependent neural reward responses, our study reveals similarities in neural mechanisms modulated by infant-mother and dog-owner attachment. [Display omitted]
