Action selection |
The selecting of an action during a single cognitive cycle |
Saccade of the eyes, a sniff |
Affect |
A general term for arousal through feelings and emotions |
|
Attention |
The process of attending to some portion of the incoming percept and of local associations |
|
Attention codelet |
A codelet that attempts to train attention on some particular kind of information |
Expectation codelet, intention codelet |
Automatized action |
An action that requires no environmental information |
Walking in an adult animal is mostly automatized |
Autonomous agent |
A system situated in, and part of, an environment, which senses that environment, and acts on it, over time, in pursuit of its own agenda, so as to affect what it senses in the future. |
Animals, humans, some mobile robots, some software agents |
Behavior |
Goal context, a collection of behavior codelets that can achieve a particular goal |
|
Behavior codelet |
A codelet that can execute some particular, specialized task |
|
Behavior stream |
A goal context hierarchy |
|
Bottom-up perception |
Perception occurring during a single cognitive cycle |
Immediate recognition |
Coalition of codelets |
Consists of attention codelet(s) together with information codelets that compete to have their content attended to |
|
Cognition |
The entire, sometimes complex, process of choosing what to do next on the basis of sensory input |
|
Cognitive Cycle |
The continual sense-cognize-act cycle of every waking autonomous agent |
In animals, humans, autonomous robots, software agents |
Competition for attention |
A competition to decide what perceptual information and local associations are to be attended to |
Information carrying more affect have an advantage |
Conscious content |
Information from working memory buffers and local associations that is broadcast during each cognitive cycle |
Perceptual information, memories of events |
“Consciousness” |
Functional consciousness whose role is specified in Global Workspace theory and in the IDA cognitive cycle |
|
Consolidation |
The movement of transient episodic memory contents to declarative memory |
|
Content-addressable memory |
A memory the contents of which can be found by cuing with part of the desired content without knowing a memory address |
Episodic memory in we humans |
Declarative memory |
Episodic memory long-term memory capability |
|
Deliberative process |
Options may be constructed and evaluated, and plans created |
Portia jumping spider stalking prey |
Drive |
A primitive motive generator |
Hunger, mating |
Emotions |
Feelings with cognitive content |
Fear, anger, shame |
Episodic learning |
The encoding of events in episodic memory |
|
Episodic memory |
Associative, content-addressable, memory for events, the what, the where, the when |
Where food was cached |
Expectation codelet |
An attention codelet that watches for the result of some behavior(s) |
|
Feelings |
Specific arousals as implementations of motivation and of learning modulation |
Hunger, fear, urge to mate, pleasure, pain |
Goal |
Desire to restructure the environment, or an agent’s relation to it, in some particular way |
To drink orange juice |
Goal context |
A potential goal, consisting of a coalition procedures which, together, could accomplish the goal |
|
Goal context hierarchies |
Connected streams of goal contexts (behaviors), can be thought of as high-level, partial plans of actions |
|
Information codelets |
Codelets that carry information and participate in coalitions that compete for attention |
|
Informationally mediated action |
Requires information from the environment for its enactment |
A predator in pursuit of prey |
Intention |
The resolve of an animal (agent) to achieve some particular goal |
Intention to drink orange juice |
Intention codelet |
An attention codelet that watches for information relevant to achieving some particular goal |
|
Long-term working memory |
Memory buffer than holds percepts and local associations for the competition of attention |
|
Meaning |
An interpretation of sensory data so as to make it of use to the agent |
Identification, categorization, relations |
Mental images |
Images produced internally from any of the sensory modalities, internal virtual reality |
Visual image, hearing a tune in one’s head |
Metacognitive process |
Thinking about thinking |
Only in humans? |
Percept |
The meaning assigned to sense data during a single cycle |
|
Perception |
The process of assigning meaning to incoming sensory data |
The color red, a sound |
Perceptual learning |
Learning recognition of new objects, new categorizations, new relationships |
|
Procedural learning |
Learning to perform new motor behaviors, or to improve the performance of existing behaviors. |
|
Procedural memory |
The storage of procedures for executing behaviors |
Running, eating, mating |
Reactive process |
Volition or action selection that is not deliberative |
|
Reinforcement |
The pleasure or pain that results in procedural learning |
|
Top-down perception |
Perception occurring during multiple cognitive cycles |
Recognition over a second or two |
Transient episodic memory |
Episodic memory with decay times measured in hours or a day or so |
|
Volition |
The process of arriving at a goal |
|
Working memory buffers |
Buffers whose contents serve to cue transient episodic and declarative memory |
