چکیده

This paper discusses our views on the future of the field of cognitive architectures, and how the scientific questions that define it should be addressed. We also report on a set of requirements, and a related architecture design, that we are currently investigating as part of the CoSy project. 1 What Are Architectures? The first problem we face as researchers in the field of cognitive architectures is defining exactly what we are studying. This is important because the term “architecture” is so widely used in modern technological fields. An agent’s cognitive architecture defines the information-processing components within the “mind” of the agent, and how these components are structured in relation to each other. Also, there is a close link between architectures and the mechanisms and representations used within them (where representations can be of many kinds with many functions). Langley and Laird (2002) describe a cognitive architecture as including “those aspects of a cognitive agent that are constant over time and across different application domains”. We extend this to explicitly allow architectures to change over time, either by changing connection patterns, or altering the components present. Excluding such changes from the study of architectures may prevent the discussion of the development of architectures for altricial informationprocessing systems (Sloman and Chappell, 2005).

Curiosity and the Development of Question Generation Skills

The current study investigates the relationship between children’s curiosity and question asking ability. Generation of two types of questions was assessed: identification (yes/no questions asked to identify a target from an array) and understanding questions, asked to learn more about a topic. The latter was related to children’s curiosity, as was the ability to recognize the effectiveness of ...

Cognitive Architecture Requirements for Achieving AGI

We outline eight characteristics of the environments, tasks, and agents important for human-level intelligence. Treating these characteristics as influences on desired agent behavior, we then derive twelve requirements for general cognitive architectures. Cognitive-architecture designs that meet the requirements should support human-level behavior across a wide range of tasks, embedded in envir...

Learning biology through research papers: a stimulus for question-asking by high-school students.

Question-asking is a basic skill, required for the development of scientific thinking. However, the way in which science lessons are conducted does not usually stimulate question-asking by students. To make students more familiar with the scientific inquiry process, we developed a curriculum in developmental biology based on research papers suitable for high-school students. Since a scientific ...
