Many industries operate technologies in which multiple outputs (co-products) are jointly produced. In some settings (“vertical”) the co-products differ along a performance dimension and are substitutable. In other settings (“horizontal”) the co-products differ in their applications and are not substitutable. In both cases, three important attributes of a co-product technology are its processing...

The cognitive theory of true conditions (CTTC) is a proposal to describe the model-theoretic semantics of symbolic cognitive architectures and design the implementation of cognitive abilities. The CTTC is formulated mathematically using the multi-optional many-sorted past present future(MMPPF) structures. This article defines mathematically the MMPPF structures and the formal languages proposed...

In this work an Intelligent Tutoring System (ITS) is presented that is able to enrich its knowledge base, merging both partially structured and unstructured information in a unique internal representation framework. The system gathers new information about the domain in response to both a curiositymechanism and sensory stimuli coming from the interaction with the user. The architecture is an ev...

Experimental research on decision making has been mainly focused on binary perceptual tasks. The generally accepted models describing the decision process in these tasks are the integrator models. These models suggest that perceptual evidence is accumulated over time until a decision is made. Therefore, the final decision is based solely on recent perceptual information. In behaviorally more re...

Whereas adults exchange conversational turns very rapidly, children often respond after long gaps. However, it has been proposed that the infrastructure necessary to take turns develops in infancy. Why are children slow to respond to turns? Adults’ turn-taking skills, it has been argued, rely on an ability to both predict when the current turn will end and prepare a response as soon as possible...

since the government, following the shi’ie doctrine, paid special attention to art and architecture, the school of isfahan found the opportunity to manifest the shi’ite beliefs in architecture. the rare combination of art, shi’ism and illumination gave this era a unique identity, which manifested itself more or less in the isfahan school of art and architecture. shia influence in the political ...

This paper is an overview of the Independent Core Observer Model (ICOM) Cognitive Extension Architecture which is a methodology or 'pattern' for producing a self-motivating computational system that can be self-aware. ICOM is as a system for abstracting standard cognitive architecture from the part of the system that can be selfaware and a system for assigning value on any given idea or 'though...

Linguistic communication relies on non-linguistic context to convey meaning. That context might include, for instance, recent or long-term experience, semantic knowledge of the world, or objects and events in the immediate environment. In this paper, we describe embodied agents instantiated in Soar cognitive architecture that use context derived from their linguistic, perceptual, procedural and...

This paper presents JUDGEMAP2 model for judgment based on DUAL cognitive architecture. Context is considered like the content of WM that comprises both some external elements from the surrounding environment and some internal memories elicited from the LTM. The paper focuses on the mechanisms of construction of the dynamic content of the WM. In JUDGEMAP2, the mechanism responsible for building ...

Cognitive Architectures are theories of cognition that try to capture the essential representations and mechanisms that underlie cognition. Research in cognitive architectures has gradually moved from a focus on the functional capabilities of architectures to ability to model the details of human behavior, and, more recently, brain activity. Although there are many different architectures, they...
