In this paper we present a model of generative proto-imitation that replicates external signals without associating with objects, as in higher-level imitation. A mixed population of adults, that have fixed associations objectssignals, and infants, that do not have associations but imitate unconditionally, endowed with a kinship and interaction structure, allows infants to develop signal affinit...

Here I discuss: (1) historical precedents that have resulted in comparative psychologists accepting the two-action method as the "gold standard" in laboratory investigations of imitation learning, (2) evidence suggesting that the two-action procedure may not be adequate to answer questions concerning the role of imitation in the development of traditional behaviors of animals living in natural ...

Environmental sounds are very helpful in understanding environmental situations and in telling the approach of danger, and sound-imitation words (sound-related onomatopoeia) are important expressions to inform such sounds in human communication, especially in Japanese language. In this paper, we design a method to recognize sound-imitation words (SIWs) for environmental sounds. Critical issues ...

Learning by imitation is a powerful process for acquiring new knowledge, but there has been little research exploring imitation’s potential in the problem solving domain. Classical problem solving techniques tend to center around reinforcement learning, which requires significant trial-and-error learning to reach successful goals and problem solutions. Heuristics, hints, and reasoning by analog...

Vocal imitation is a phenotype that is unique to humans among all primate species, and so an understanding of its neural basis is critical in explaining the emergence of both speech and song in human evolution. Two principal neural models of vocal imitation have emerged from a consideration of nonhuman animals. One hypothesis suggests that putative mirror neurons in the inferior frontal gyrus p...

Children with autism exhibit significant deficits in their ability to spontaneously imitate the play actions and descriptive gestures of others. Reciprocal imitation training (RIT) is a naturalistic imitation intervention designed to teach spontaneous imitation skills during play. This study assessed the effectiveness of parent-implemented RIT using a multiple-baseline design across three young...

In this paper, we tackle the problem of opportunistic spectrum access in large-scale cognitive radio networks,where the unlicensed Secondary Users (SU) access the frequency channels partially occupied by the licensedPrimary Users (PU). Each channel is characterized by an availability probability unknown to the SUs. We applyevolutionary game theory to model the spectrum access proble...

Children are exceptional, even 'super,' imitators but comparatively poor independent problem-solvers or innovators. Yet, imitation and innovation are both necessary components of cumulative cultural evolution. Here, we explored the relationship between imitation and innovation by assessing children's ability to generate a solution to a novel problem by imitating two different action sequences d...

Imitation, the replication of observed behaviors, has been proposed as the crucial social learning mechanism for the generation of humanlike cultural complexity. To date, the single published experimental microsociety study that tested this hypothesis found no advantage for imitation. In contrast, the current paper reports data in support of the imitation hypothesis. Participants in "microsocie...

Non-human great apes appear to be able to acquire elaborate skills partly by imitation, raising the possibility of the transfer of skill by imitation in animals that have only rudimentary mentalizing capacities: in contrast to the frequent assumption that imitation depends on prior understanding of others' intentions. Attempts to understand the apes' behaviour have led to the development of a p...
