cognitive-based human errors have major contribution to performance and safety in working environment. this study designed to develop a measurement tool in order to evaluate this type of errors in the occupational settings. an occupational cognitive failure questionnaire (ocfq) was developed. content validity of the ocfq was performed using a quantitative approach. reliability of questionnaire ...

Research background Research conducted under the rubric of Cognitive Flexibility Theory examined learning and performance in medical education and, in particular, how people learn and understand the cardiovascular system.1,2 The research identified characteristics of learning material and performance situations that cause cognitive difficulty for learners and operators. It also determined how p...

Adding student collaboration to an intelligent tutoring system could leverage the benefits of both approaches. We have incorporated a mutual peer tutoring script, where students of similar abilities take turns tutoring each other, into the Cognitive Tutor Algebra. In this paper, we identify three design principles for peer tutoring, and discuss how they were realized in our peer tutoring script...

We describe a cognitive model of a collaborative agent that can serve as the basis for automated systems that must collaborate with other agents, including humans, to solve problems. This model builds on standard approaches to cognitive architecture and intelligent agency, as well as formal models of speech acts, joint intention, and intention recognition. The model is nonetheless intended for ...

Alcoholic beverages are assumed to be the most popular drinks which are being consumed after water. Though for people who drink alcohol in excessive amounts longer time would be taken to become dependent in comparison with other drugs. Alcohol causes more severe medical and social harm as well as many fatal accidents for its users. Non-medical interventions are still on the top of the list of e...

Introduction: Ionizing radiation is non-surgical treatment of brain tumors and metastases. Preclinical studies have showed main insights into harmful effects of radiation on the nervous system in vivo and in vitro. Cognitive impairment such as progressive memory, executive and attention performance deficits indicates a significant risk for patients experiencing conventional rad...

Cognitive radio technology, a revolutionary communication paradigm that can utilize the existing wireless spectrum resources more efficiently, has been receiving a growing attention in recent years. As network users need to adapt their operating parameters to the dynamic environment, who may pursue different goals, traditional spectrum sharing approaches based on a fully cooperative, static, an...

Modeling crowd behaviors is an important challenge for intelligent virtual agents. We propose a general cognitive model of simulating crowd behaviors, based on Festinger’s Social Comparison Theory (SCT), a prominent social psychology theory. We present the use of the SCT model (using the Soar cognitive architecture) in the generation of imitational behavior in loosely-coupled groups and show th...
