In this paper, we investigate the benefits and drawbacks of different approaches for solving a cooperative foraging task with two robots. We compare a classical clonal approach with an additional approach which favors the evolution of heterogeneous behaviors according to two defining criteria: the evolvability of the cooperative solution and the efficiency of the coordination behaviors evolved....

We compare four different risk-taking propensity measures on their ability to describe and to predict actual risky behavior in the domain of health. The risk-taking propensity measures we compare are: (1) a general measure of risk-taking propensity derived from a one-item survey question (Dohmen et al., 2011), (2) a risk aversion index calculated from a set of incentivized monetary gambles (Hol...

this paper examines the theoretical rationales and practical aspects of task-based language teaching (tblt) with particular reference to research findings in efl/esl contexts. the definitional scope of the term ‘task’, polarizations in terms of task vs. non-task, and its relation to different language teaching approaches have engendered conceptual and methodological ambiguities.  moreover, fact...

Previous reviews of the literature on the relationship between age and job performance have largely focused on core task performance but have paid much less attention to other job behaviors that also contribute to productivity. The current study provides an expanded meta-analysis on the relationship between age and job performance that includes 10 dimensions of job performance: core task perfor...

Identifying the traffic dispatcher error behaviors that frequently result in the occurrence of metro accidents is beneficial to prevent error behaviors and mitigate their consequences. Yet, there is no theoretical framework available for metro safety officers in investigating and classifying traffic dispatcher error behaviors. This article presents a structured procedure to analyze traffic disp...

The effects of intracerebroventricular (ICV) injection of ethylcholine aziridinium ion (AF64A) (3 nmole/2 microliter, each lateral ventricule), a putative selective cholinotoxin, on learning behaviors and choline acetyltransferase (ChAT) activity were studied in rats. AF64A-treated rats (AF64A-rat) exhibited deficient performance in a passive avoidance task and a delayed alternation task in the...

A psychological experiment was conducted to straightforwardly investigate the effects of polite behaviors expressed by robots in Japan, using a small-sized humanoid robot that performed four types of behaviors with voice task instructions. Results of the experiment suggested that the subjects who experienced “deep bowing” motion of the robot felt it more extrovert than those who experienced “ju...

How to enable robotic compliant manipulation has become a critical problem in the robotics field. Inspired by biomimetic adaptive control strategy, this article presents novel representation model named human-like movement primitives (Hl-CMPs) which could allow robot learn behaviors. The state-of-the-art approaches can hardly complete profiles for specific task. Comparatively, our encode task-s...
