When individuals learn from what others tell them, the information is subject to transmission error that does not arise in learning from direct experience. Yet evidence shows that humans consistently prefer this apparently more unreliable source of information. We examine the effect this preference has in cases where the information concerns a judgment on others’ behaviour and is used to establish cooperation in a society. We present a spatial model confirming that cooperation can be sustained by gossip containing a high degree of uncertainty. Accuracy alone does not predict the value of information in evolutionary terms; relevance, the impact of information on behavioural outcomes, must also be considered. We then show that once relevance is incorporated as a criterion, second-hand information can no longer be discounted on the basis of its poor fidelity alone. Finally we show that the relative importance of accuracy and relevance depends on factors of life history and demography.

Excessive dog barking is among the leading sources of noise pollution world-wide; however, the reasons for the annoyance of barking to people remained uninvestigated. Our questions were: is the annoyance rating affected by the acoustic parameters of barks; does the attributed inner state of the dog and the nuisance caused by its barks correlate; does the gender and country of origin affect the subjects’ sensitivity to barking. Participants from Hungary (N = 100) and Brazil (N = 60) were tested with sets of 27 artificial bark sequences. Subjects rated each bark according to the inner state of the dog and the annoyance caused by the particular bark. Subjects from both countries found high-pitched barks the most annoying: however, harsh, fast-pulsing, low-pitched barks were also unpleasant. Men found high-pitched barks more annoying than the women did. Annoyance ratings showed positive correlation with assumed negative inner states of the dog, positive emotional ratings showed negative correlation with the annoyance level. This is the first indication that acoustic features that were selected for effective vocal signalling may be annoying for human listeners. Among the explanations for this effect the role of affective communication and similar bioacoustics of particular animal vocalizations and baby cries are discussed.

In robotics research with language-based interaction, simplifications are made, such that a given event can be described in a unique manner, where there is a direct mapping between event representations and sentences that can describe these events. However, common experience tells us that the same physical event can be described in multiple ways, depending on the perspective of the speaker. The current research develops methods for representing events from multiple perspectives, and for choosing the perspective that will be used for generating a linguistic construal, based on attentional processes in the system. The multiple perspectives are based on the principle that events can be considered in terms of the force driving the event, and the result obtained from the event, based on the theory of Gärdenfors. In addition, within these perspectives a further refinement can be made with respect to the agent, object, and recipient perspectives. We develop a system for generating appropriate construals of meaning, and demonstrate how this can be used in a realistic dialogic interaction between a behaving robot and a human interlocutor.

What makes a human voice agreeable is a matter of scientific discussion. Whereas prosody was shown to play a role regarding “male-female” attraction, the impact of frequency modulations in “non-sexual”, notably commercial, contexts has attracted little attention. Another point unaddressed in the literature is auditory sensitivity to short-term frequency modulations as current studies focus more on sentence. Thirty French female operators were recorded over the phone. All “bonjour” greeting words were classified in terms of frequency modulation linearity and orientation at the syllable and word levels. Then, the different voices were played back to students and seniors who had to rate each voice according to their degree of agreeableness. Listeners preferred non-monotonous voices. Differences between age-classes were greater than between sex-classes. Results suggest that short-term frequency changes are important for auditory evaluation of voice agreeableness. This study opens new research perspectives concerning the importance of prosody during consumer-seller interactions.

It is well-established that toddlers can correctly select a novel referent from an ambiguous array in response to a novel label. There is also a growing consensus that robust word learning requires repeated label-object encounters. However, the effect of the context in which a novel object is encountered is less well-understood. We present two embodied neural network replications of recent empirical tasks, which demonstrated that the context in which a target object is encountered is fundamental to referent selection and word learning. Our model offers an explicit account of the bottom-up associative and embodied mechanisms which could support children’s early word learning and emphasises the importance of viewing behaviour as the interaction of learning at multiple timescales.

This article discusses the importance of social interaction for the development of the representations for symbolic communication. We suggest that there is no need to distinguish between different representational systems emerging at different stages of development. Instead, we propose that representations are rich right from the beginning of a child’s life, and that they are driven mainly by acting and interacting in the physical and social world. The more variety in a child’s interactional experience (i.e., synchrony, sequentiality, and prediction), the more enriched and abstracted the representations become. We review literature providing evidence for the ways in which infants’ development toward symbolic communication benefits from repeated social (inter)action and consider some implications for computational approaches.
