This paper describes an analytically tractable model of balanced growth that is consistent with the observed size distribution of firms. Growth is the result of idiosyncratic firm productivity improvements, selection of successful firms, and imitation by entrants. Selection tends to improve aggregate productivity at a fast rate if entry and imitation are easy. The empirical phenomenon of Zipf ’...

Children learn many skills through imitation. An important example is the development of language, where imitation of social and communicative behaviors plays a critical role. It is widely reported in the literature that children with autism have an imitation deficit. This paper presents a study on the effect of robotic versus human intervention on the imitation skills of a child with autism. T...

Imitation in the form of repeating speech sounds, accents, and words plays a foundational role in the normal acquisition and development of language (Meltzoff et al., 2009; Adank et al., 2013) eventually contributing to a life-long fine-tuning of communication skills (Tannen, 1987; Delvaux and Soquet, 2007). Imitation of prosodic and paralinguistic features may be intentional in certain context...

Abstract The major aim of the current study is to verify whether an interdependence between self-imitation practice and L2 pronunciation improvement in process second-language acquisition stronger than traditional imitation tasks. 35 Polish students Applied Linguistics (at English level B2+) divided into two groups performed exercises order improve their skills. Three acoustic parameters were c...

Monkeys recognize when they are being imitated, but they seem unable to learn by imitation. These facts make sense if imitation is seen as two different capacities: social mirroring, when actions are matched and have social benefits; and learning by copying, when new behavioural routines are acquired by observation.

Objective: The aim of this paper is to bridge the gap between the corpus of imitation research and video based intervention (VBI) research, and consider the impact imitation skills may be having on VBI outcomes and to what extent this can be utilised to improve outcomes. Method: A review of the imitation literature was conducted focusing on imitation skill deficits in children with autism follo...

The aim in this study was to investigate the emergence of immediate imitation, deferred imitation and synchronic imitation in human infants through the second year. A longitudinal study was conducted of eighty-six infants at three monthly intervals from 12through to 24-months-of-age. At each session the infants were assessed for immediate, deferred and synchronic imitation. Immediate and deferr...

OBJECTIVE The aim of this paper is to bridge the gap between the corpus of imitation research and video-based intervention (VBI) research, and consider the impact imitation skills may be having on VBI outcomes and highlight potential areas for improving efficacy. METHOD A review of the imitation literature was conducted focusing on imitation skill deficits in children with autism followed by ...
