“…Consistently to results of previous studies (Gogoleva et al, 2008, 2009, 2010b,c), in the presence of humans, Unselected and Aggressive foxes produced coughs and snorts and never emitted cackles and pants, while Tame foxes produced cackles and pants and never emitted coughs or snorts. Also, in accordance to previous data for comparison of vocal activities of these three strains under other test designs (Gogoleva et al, 2008, 2010b), Aggressive foxes showed higher proportions of time spent vocalizing throughout the test than Unselected or Tame foxes.…”

“…The calling rate represents a reliable indicator of the degree of emotional arousal in silver foxes (Gogoleva et al, 2010b,c) and other mammals (Weary & Fraser, 1995; Weary et al, 1997; Rendall, 2003; Volodin et al, 2009). Therefore, we can suggest reasonable that the human appearance before the cage provokes the high level of emotional arousal of Tame foxes.…”

“…During handling, Tame foxes even grip human's hand weakly by teeth, to not give them gone (Trut, 1999). In contrast, Aggressive foxes and Unselected for behavior control group of silver foxes, respond emotionally negatively to all humans (Trut, 1999; Gogoleva et al, 2008, 2010a,c; Trut et al, 2009). The precise knowledge of attitudes of foxes of each strain to approaching humans is coming from behavioral tests (Trut, 1980, 1999; Kukekova et al, 2008; Gogoleva et al, 2009).…”

Domestication affects behavioral and vocal responses, involved in communication with humans; in particular, those that attract human attention. In this study, we found that silver foxes of Tame strain, experimentally domesticated for a few tenses generation, displayed bursts of vocal activity during the first minute after appearance of an unfamiliar human, that faded quickly during the remaining time of the test, when the experimenter stayed passively before the cage. Distinctively, foxes of Aggressive strain, artificially selected for tenses generations for aggressive behavior toward humans, and the control group of Unselected for behavior silver foxes kept steady levels of vocal activity for the duration of the tests. We found also that Aggressive foxes vocalized for a larger proportion of time than Unselected foxes for all five minutes of the test. We discuss the obtained data in relation to proposal effects of domestication on mechanisms directed to involving people into human-animal interactions and structural similarity between human laughter and vocalization of Tame foxes.

“…Current empirical research revealed cross-taxa similarities in the acoustical conveyance of emotions across different mammalian groups (e.g., [17], [18], [19], [20], [21], [22], [23]) which show similarities to prosodic cues in human speech and non-verbal vocalizations (e.g., [3], [6], [24], [25]). Various models were developed to characterize the universal relationship between the structure of vocalizations and their emotional content (e.g., [26], [27], [28], [29]).…”

The Voice of Emotion across Species: How Do Human Listeners Recognize Animals' Affective States?

Voice-induced cross-taxa emotional recognition is the ability to understand the emotional state of another species based on its voice. In the past, induced affective states, experience-dependent higher cognitive processes or cross-taxa universal acoustic coding and processing mechanisms have been discussed to underlie this ability in humans. The present study sets out to distinguish the influence of familiarity and phylogeny on voice-induced cross-taxa emotional perception in humans. For the first time, two perspectives are taken into account: the self- (i.e. emotional valence induced in the listener) versus the others-perspective (i.e. correct recognition of the emotional valence of the recording context). Twenty-eight male participants listened to 192 vocalizations of four different species (human infant, dog, chimpanzee and tree shrew). Stimuli were recorded either in an agonistic (negative emotional valence) or affiliative (positive emotional valence) context. Participants rated the emotional valence of the stimuli adopting self- and others-perspective by using a 5-point version of the Self-Assessment Manikin (SAM). Familiarity was assessed based on subjective rating, objective labelling of the respective stimuli and interaction time with the respective species. Participants reliably recognized the emotional valence of human voices, whereas the results for animal voices were mixed. The correct classification of animal voices depended on the listener's familiarity with the species and the call type/recording context, whereas there was less influence of induced emotional states and phylogeny. Our results provide first evidence that explicit voice-induced cross-taxa emotional recognition in humans is shaped more by experience-dependent cognitive mechanisms than by induced affective states or cross-taxa universal acoustic coding and processing mechanisms.

“…Wild-type Unselected foxes produced cough and snort toward humans similarly to Aggressive foxes (Gogoleva et al, 2008a,b, 2010). This suggests that the directional selection for aggressiveness toward humans did not affect vocalization toward humans in the silver fox, whilst the directional selection for tameness, mimicking the process of historical domestication targeted at the tolerance of animals toward humans (Belyaev, 1979), drastically affected vocalization toward humans in the silver fox.…”

We examined the production of different vocalizations in three strains of silver fox (Unselected, Aggressive, and Tame) attending three kinds of behavior (aggressive, affiliative, and neutral) in response to their same-strain conspecifics. This is a follow up to previous experiments which demonstrated that in the presence of humans tame foxes produced cackles and pants but never coughed or snorted, whilst Aggressive foxes produced coughs and snorts but never cackled or panted. Thus, cackle/pant and cough/snort were indicative of the Tame and Aggressive fox strains respectively toward humans. Wild-type Unselected foxes produced cough and snort toward humans similarly to Aggressive foxes. Here we found that vocal responses to conspecifics were similar in Tame, Aggressive and Unselected fox strains. Both cackle/pant and cough/snort occurred in foxes of all strains. The difference in the use of cackle/pant and cough/snort among these strains toward humans and toward conspecifics suggest that silver foxes do not perceive humans as their conspecifics. We speculate that these vocalizations are produced in response to a triggering internal state, affiliative or aggressive, that is suppressed by default in these fox strains toward humans as a result of their strict selection for tame or aggressive behavior, whilst still remaining flexible toward conspecifics.
