Artificial Intelligence Review. To date, the number of existing architectures has reached several hundred, but most of the existing surveys do not reflect this growth and instead focus on a handful of well-established architectures. In this survey we aim to provide a more inclusive and high-level overview of the research on cognitive architectures. Our final set of 84 architectures includes 49 that are still actively developed, and borrow from a diverse set of disciplines, spanning areas from psychoanalysis to neuroscience. To keep the length of this paper within reasonable limits we discuss only the core cognitive abilities, such as perception, attention mechanisms, action selection, memory, learning, reasoning and metareasoning.
In the remainder of this section we will provide brief descriptions of the visual processing in various architectures. Besides defining these criteria and applying them to a range of cognitive architectures, Sun also pointed out the lack of clearly defined cognitive assumptions and methodological approaches, which hinder progress in studying intelligence. Sex description like this also raise interesting questions whether it makes sense to try and segregate symbolic parts of cognition from sub-symbolic. A combination of these factors makes video games a very valuable test platform Cognitive franklin model skill models of human cognition. FRM brings the key ingredients of most successful psychotherapies - the provision of education, Llong fuck movies convincing rationale for the treatment, enhancing Cognitive franklin model skill of improvement, provision of support and encouragement, behavioral treatments - and can effectively bridge to motivational enhancement and stages of change. A compounding factor for evaluation is that cognitive architectures comprise both theoretical and engineering components, which Sexy legg pics to a combinatorial explosion of possible implementations. It is believed to be a part of cortical processes and is often used in the computational models of the brain to make a selection from a set of decisions depending on the input. One such example is saliency, which models the ability to prioritize visual stimuli based on Cognitive franklin model skill features or relevance to the task. Reactive actions are executed bypassing action selection. Arguably, some of these categories may seem more important than the others and historically attracted more attention further discussed in Sect.

Developing logic allows an individual to think in abstract terms and reach conclusions and solutions by using existing knowledge to evaluate new information. This prepares offenders to follow laws in society. Population: Children, agesand their non-offending parents or caregivers. It is critical to note that the author of the report is always the expert on the report. Skip Submit. Training: TF-CBT training is available to therapists with graduate degrees in a mental health discipline. While these staff receive specialized training, all staff working at a correctional center where a Cognitive Community exists are expected Cognitive franklin model skill attend a hour Cognitive Community staff training. Others get better results by juggling a group of taskseither because all are related and require each other in some way, or because rapid cycling among different tasks relieves boredom. Following Rules Within this community, just as in society, offenders are expected to follow rules and standards that emphasize right living. Jessica was instrumental in developing the first Cognitive Community Program in the state of Virginia. Living in this community Soiled panty photos challenges offenders to step outside of their comfort zone. Maladaptive beliefs are identified and replaced over time.
It teaches all persons they have a filtering system which is labeled the "belief window," and that all of us are constantly placing principles on our belief window as a function of age.

It teaches all persons they have a filtering system which is labeled the "belief window," and that all of us are constantly placing principles on our belief window as a function of age. Once we accept a principle, we attach rules to it. Our behavior follows our principles and as a result, our behavior generally has an easily predictable result; e. The model also includes four basic human needs: to live, to feel important, to love and be loved, and variety.
There are seven "natural laws" that accompany the Franklin Reality Model: 1. If the results of your behavior do not meet your needs, there is an incorrect principle in your belief window. Results take time to measure. Growth is the process of changing principles on your belief window. If your self-worth is dependent on anything external, you are in big trouble. Addictive behavior is the result of deep and unmet needs of the four above mentioned needs. The mind will naturally seek harmony when presented with two opposing principles.
When the results of your behavior do meet your needs you experience inner peace. The "laws" lay out a path to develop self-reflection, self-responsibility, delay of gratification or impulse control, self-efficacy, and self-determination, all of which counter the impulse to abuse substances.
As they practice tracing the natural outcomes of their beliefs or start from the consequences in their lives that they dislike, and trace back to the underlying belief system, they engage in a cognitive restructuring process.
The next step is to choose and practice new beliefs and behaviors that can lead to desirable outcomes. Maladaptive beliefs are identified and replaced over time. The model is further used to strengthen engagement in other aspects of recovery such as taking responsibility to resolve legal obligations, repair of family relationships, and engagement with community recovery support networks including step programs.
FRM brings the key ingredients of most successful psychotherapies - the provision of education, a convincing rationale for the treatment, enhancing expectations of improvement, provision of support and encouragement, behavioral treatments - and can effectively bridge to motivational enhancement and stages of change. This model is a theoretical base within many of our treatment groups. It is where clients learn, develop and practice positive coping skills.
Reality Therapy was developed by William Glasser, who holds the view that people who are behaving in inappropriate ways do not need help to find a defense for their behavior; rather, they need help to acknowledge their behavior as being inappropriate, and then learn how to act in a more logical and productive manner.

Artificial Intelligence Review. To date, the number of existing architectures has reached several hundred, but most of the existing surveys do not reflect this growth and instead focus on a handful of well-established architectures. In this survey we aim to provide a more inclusive and high-level overview of the research on cognitive architectures. Our final set of 84 architectures includes 49 that are still actively developed, and borrow from a diverse set of disciplines, spanning areas from psychoanalysis to neuroscience.
To keep the length of this paper within reasonable limits we discuss only the core cognitive abilities, such as perception, attention mechanisms, action selection, memory, learning, reasoning and metareasoning. In order to assess the breadth of practical applications of cognitive architectures we present information on over practical projects implemented using the cognitive architectures in our list.
We use various visualization techniques to highlight the overall trends in the development of the field. In addition to summarizing the current state-of-the-art in the cognitive architecture research, this survey describes a variety of methods and ideas that have been tried and their relative success in modeling human cognitive abilities, as well as which aspects of cognitive behavior need more research with respect to their mechanistic counterparts and thus can further inform how cognitive science might progress.
A diagram showing cognitive architectures found in literature surveys and on-line sources shown with blue and orange colors respectively. The architectures in the diagram are sorted in the descending order by the total number of references in the surveys and on-line sources for each architecture.
Titles of the architectures covered in this survey are shown in red. All visualizations in this paper are made using the D3. Interactive versions of the figures are available on the project website. Since there is no exhaustive list of cognitive architectures, their exact number is unknown, but it is estimated to be around three hundred, out of which at least one-third of the projects are currently active.
We also included more recent projects not yet mentioned in the survey literature. Even though the theoretical and practical contributions of the major architectures are undeniable, they represent only a part of the research in the field. Thus, in this review the focus is shifted away from the deep study of the major architectures or discussion of what could be the best approach to modeling cognition, which has been done elsewhere. Further, a new Standard Model of the Mind is proposed as a reference model born out of consensus between the three architectures.
We hope to inform the future cognitive architecture research by introducing the diversity of ideas that have been tried and their relative success. To make this survey manageable we reduced the original list of architectures to 84 items by considering only implemented architectures with at least one practical application and several peer-reviewed publications.
We do not explicitly include some of the philosophical architectures such as CogAff Sloman , Society of Mind Minsky , Global Workspace Theory GWT Baars and Pandemonium Theory Selfridge , however we examine cognitive architectures heavily influenced by these theories e. We also exclude large-scale brain modeling projects, which are low-level and do not easily map onto the breadth of cognitive capabilities modeled by other types of cognitive architectures.
Further, many of the existing brain models do not yet have practical applications, and thus do not fit the parameters of the present survey. Of these projects 49 are currently active. A timeline of 84 cognitive architectures featured in this survey. Each line corresponds to a single architecture. The architectures are sorted by the starting date, so that the earliest architectures are plotted at the bottom of the figure.
Since the explicit beginning and ending dates are known only for a few projects, we recovered the timeline based on the dates of the publications and activity on the project web page or on-line repository.
Colors of the lines correspond to different types of architectures: symbolic green , emergent red and hybrid blue. According to this data there was a particular interest in symbolic architectures since mids until early s, however after s most of the newly developed architectures are hybrid.
Emergent architectures, many of which are biologically-inspired, are more evenly distributed but remain a relatively small group. In the following sections, we will provide an overview of the definitions of cognition and approaches to categorizing cognitive architectures. As one of our contributions, we map cognitive architectures according to their perception modality, implemented mechanisms of attention, memory organization, types of learning, action selection and practical applications.
In the process of preparing this paper, we thoroughly examined the literature and this activity led to an extensive bibliography of more than relevant publications. We provide this bibliography, as well as interactive versions of the diagrams in this paper on our project webpage. Cognitive architectures are a part of research in general AI, which began in the s with the goal of creating programs that could reason about problems across different domains, develop insights, adapt to new situations and reflect on themselves.
Similarly, the ultimate goal of research in cognitive architectures is to model the human mind, eventually enabling us to build human-level artificial intelligence. To this end, cognitive architectures attempt to provide evidence what particular mechanisms succeed in producing intelligent behavior and thus contribute to cognitive science. Moreover, the body of work represented by the cognitive architectures covered in this review, documents what methods or strategies have been tried previously and what have not , how they have been used, and what level of success has been achieved or lessons learned, all important elements that help guide future research efforts.
For AI and engineering, documentation of past mechanistic work has obvious import. But this is just as important for cognitive science, since most experimental work eventually attempts to connect to explanations of how observed human behavior may be generated.
According to Russell and Norvig artificial intelligence may be realized in four different ways: systems that think like humans, systems that think rationally, systems that act like humans, and systems that act rationally. The existing cognitive architectures have explored all four possibilities. For instance, human-like thought is pursued by the architectures stemming from cognitive modeling.
In this case, the errors made by an intelligent system should match the errors typically made by people in similar situations. This is in contrast to rationally thinking systems which are required to produce consistent and correct conclusions for arbitrary tasks.
A similar distinction is made for machines that act like humans or act rationally. Machines in either of these groups are not expected to think like humans, only their actions or behavior is taken into account. Given the multitude of approaches that may lead to human-level AI and in the absense of clear definition and general theory of cognition, each cognitive architecture is built on a particular set of premises and assumptions, making comparison and evaluation of progress across architectures difficult.
Besides defining these criteria and applying them to a range of cognitive architectures, Sun also pointed out the lack of clearly defined cognitive assumptions and methodological approaches, which hinder progress in studying intelligence. However, a quick look at the existing cognitive architectures reveals persisting disagreements in terms of their research goals, structure, operation and application.
Given the issues with defining intelligence Legg and Hutter , a more practical solution is to treat it as a set of competencies and behaviors demonstrated by the system. While no comprehensive list of capabilities required for intelligence exists, several broad areas have been identified that may serve as guidance for ongoing work in the cognitive architecture domain.
These are further split into subareas. Arguably, some of these categories may seem more important than the others and historically attracted more attention further discussed in Sect. At the same time, implementing even a reduced set of abilities in a single architecture is a substantial undertaking. Majority of architectures study particular aspects of cognition, e. In view of such diversity of existing architectures and their proclaimed goals, naturally, the question then arises as to what system can be considered a cognitive architecture.
Different opinions on this can be found in the literature. Laird a discusses how cognitive architectures differ from other intelligent software systems. Cognitive architectures, on the other hand, must change through development and efficiently use knowledge to perform new tasks.
Furthermore, he suggests that toolkits and frameworks for building intelligent agents e. According to Sun, psychologically based cognitive architectures should facilitate the study of human mind by modeling not only the human behavior but also the underlying cognitive processes. The same applies to many biomimetic and neuroscience-inspired cognitive architectures that model cognitive processes on a neuronal level e. However, when it comes to less common or new projects, the reasons for considering them are less clear.
However, the question is where does this work stand with respect to cognitive architectures? Overall, the DeepMind research addresses a number of important issues in AI, such as natural language understanding, perceptual processing, general learning, and strategies for evaluating artificial intelligence.
Although particular models already demonstrate cognitive abilities in limited domains, at this point they do not represent a unified model of intelligence. Their main argument is that AI is too complex to be built all at once and instead its general characteristics should be defined first.
Two such characteristics of intelligence are defined, namely, communication and learning, and a concrete roadmap are proposed for developing them incrementally.
Currently, there are no publications about developing such a system, but overall the research topics pursued by FAIR align with their proposal for AI and also the business interests of the company. Common topics include visual processing, especially segmentation and object detection, data mining, natural language processing, human-computer interaction and network security.
Since the current deep learning techniques are mainly applied to solving practical problems and do not represent a unified framework we do not include them in this review. However, given their prevalence in other areas of AI, deep learning methods will likely play important role in the cognitive architectures of the future.
In view of the above discussion and to ensure both inclusiveness and consistency, cognitive architectures in this survey are selected based on the following criteria: self-evaluation as cognitive, robotic or agent architecture, existing implementation not necessarily open-source , and mechanisms for perception, attention, action selection, memory and learning.
Furthermore, we considered the architectures with at least several peer-reviewed papers and practical applications beyond simple illustrative examples. For the most recent architectures still under development, some of these conditions were relaxed. An important point to keep in mind while reading this survey is that cognitive architectures should be distinguished from the models or agents that implement them. For instance, ACT-R, Soar, HTM and many other architectures serve as the basis for multiple software agents that demonstrate only a subset of capabilities declared in theory.
On the other hand, some agents may implement extra features that are not available in the cognitive architecture. A good example is the perceptual system of Rosie Kirk and Laird , one of the robotic agents implemented in Soar, whereas Soar itself does not include a real perceptual system for physical sensors as part of the architecture. Unfortunately, in many cases the level of detail presented in the publications does not allow one to judge whether the particular capability is enabled by the architectural mechanisms and is common among all models or is custom-made for a particular application.
Therefore, to avoid confusion, we do not make this distinction and list all capabilities demonstrated by the architecture.
In general we use the most recent variant of the architecture for analysis and assume that the features and abilities of the previous versions are retained in the new version unless there is contradicting evidence. Many papers published within the last decade address the problem of evaluation rather than categorization of cognitive architectures. Furthermore, surveys of cognitive architectures define various capabilities, properties and evaluation criteria, which include recognition, decision making, perception, prediction, planning, acting, communication, learning, goal setting, adaptability, generality, autonomy, problem solving, real-time operation, meta-learning, etc.
A taxonomy of cognitive architectures based on the representation and processing. The order of the architectures within each group is alphabetical and does not correspond to the proportion of symbolic versus sub-symbolic elements i. Symbolic systems represent concepts using symbols that can be manipulated using a predefined instruction set. Such instructions can be implemented as if-then rules applied to the symbols representing the facts known about the world e.
ACT-R, Soar and other production rule architectures. Because it is a natural and intuitive representation of knowledge, symbolic manipulation remains very common. Although, by design, symbolic systems excel at planning and reasoning, they are less able to deal with the flexibility and robustness that are required for dealing with a changing environment and for perceptual processing. The emergent approach resolves the adaptability and learning issues by building massively parallel models, analogous to neural networks, where information flow is represented by a propagation of signals from the input nodes.
However, the resulting system also loses its transparency, since knowledge is no longer a set of symbolic entities and instead is distributed throughout the network. For these reasons, logical inference in a traditional sense becomes problematic although not impossible in emergent architectures. Naturally, each paradigm has its strengths and weaknesses. For example, any symbolic architecture requires a lot of work to create an initial knowledge base, but once it is done the architecture is fully functional.
On the other hand, emergent architectures are easier to design, but must be trained in order to produce useful behavior.
