a r t i c l e i n f o This study examined task specific effects of third-party ostracism on imitative fidelity in early childhood (N = 96, 3–6-year-olds). Start-and end-states of action sequences were manipulated to examine the effects of priming third-party ostracism versus affiliation on children's imitation of instrumental (i.e., action sequence with a different start-and end-state) versus s...

This paper investigates a two-stage model of infants' imitative learning from observed actions and their effects. According to this model, the observation of another person's action activates the corresponding motor code in the infants' motor repertoire (i.e. leads to motor resonance). The second process guiding imitative behavior results from the observed action effects. If the modeled action ...

We extend the analysis in Alós-Ferrer and Ania (2005) to allow for memory in the imitative learning process. Adding memory allows to detect and correct unprofitable deviations and makes it harder to disturb Nash equilibria with spiteful deviations that achieve a relative advantage. We show for the case of general aggregative submodular games that perfectly competitive outcomes are still stochas...

Liepmann posited that, in right handers, the left parietal lobe contains movement formulas or representations. Therefore, performance failures may be induced by degraded representations, a failure of these representations to influence motor systems or a failure of stimuli to fully access these representations. Imitation may help the performance of subjects with degraded representations. However...

The paper describes results from a simulation model of rural land use, focusing on how the relative advantages of imitative and non-imitative approaches to land use selection change under diierent circumstances. It is shown that the success ofìmitation' depends in quite complex ways on the type of imitation used, the strategies of other agents with which the imitator is interacting, and aspects...

The paper considers an imitation dynamic in the context of Cournot oligopoly. The pure ”imitate-the-best” behavior can lead to an outcome inconsistent with Cournot-Nash equilibrium. The paper extends purely imitative behavior to imperfect imitation in the two-stage model with capacities and prices. This variation in the imitative behavior improves efficiency and makes the Cournot-Nash equilibri...

We consider models of stochastic evolution in two-strategy games in which agents employ imitative decision rules. We introduce committed agents: for each strategy, we suppose that there is at least one agent who plays that strategy without fail. We show that unlike the standard imitative model, the model with committed agents generates unambiguous infinite horizon predictions: the asymptotics o...
