From a Formal Cognitive Task Model to an Implemented ACT-R Model
نویسنده
چکیده
In order to generate behavior that can be validated, a cognitive task model needs to be implemented in software. This paper first introduces a cognitive task model based on a BDI framework and then focuses on the translation of that model into the ACT-R theory and software. Problems encountered during this translation process are described and further implications are discussed. It is found that the model’s control structure matches well with ACT-R, but that the translation of its reasoning rules is complex. ACT-R’s theory of cognition does not match with properties of our task model on three issues: 1) the number of memory items that can be stored in working memory, 2) the way memory items are retrieved from long-term memory, 3) the ability to execute complex computations.

Neuro-ACT Cognitive Architecture Applications in Modeling Driver’s Steering Behavior in Turns
Cognitive Architectures (CAs) are the core of artificial cognitive systems. A CA is supposed to specify the human brain at a level of abstraction suitable for explaining how it achieves the functions of the mind. Over the years a number of distinct CAs have been proposed by different authors and their limitations and potentials were investigated. These CAs are usually classified as symbolic and...
متن کاملA Formal Semantics for the Cognitive Architecture ACT-R
The cognitive architecture ACT-R is very popular in cognitive sciences. It merges well-investigated results of psychology to a unified model of cognition. This enables researchers to implement and execute domain-specific cognitive models. ACT-R is implemented as a production rule system. Although its underlying psychological theory has been investigated in many psychological experiments, ACT-R ...
متن کاملAccounting for subliminal priming in ACT-R
This paper presents a cognitive model of a subliminal priming task, using Retrieval by ACcumulating Evidence (RACE), a model of declarative memory retrieval. RACE is implemented as an extension to the ACT-R architecture of cognition. First, we will discuss the exact implementation of RACE within the constraints imposed by ACT-R. Second, we will discuss the subliminal priming task that we modele...
متن کاملA computational model of focused attention meditation and its transfer to a sustained attention task
Although meditation and mindfulness practices are widely discussed in the scientific literature, there is little formal theory about the cognitive mechanisms that comprise it. Here we begin to develop such a theory by creating a computational cognitive model of a particular type of meditation: focused attention meditation. This model was created within Prims, a cognitive architecture similar to...
متن کاملA Computational Model for Situated Task Learning with Interactive Instruction
Learning novel tasks is a complex cognitive activity requiring the learner to acquire diverse declarative and procedural knowledge. Prior ACT-R models of acquiring task knowledge from instruction focused on learning procedural knowledge from declarative instructions encoded in semantic memory. In this paper, we identify the requirements for designing computational models that learn task knowled...
