Definition ExternallySourcedDefinition Synonym
Abductive reasoning function Abductive reasoning involves applying norms underlying hypothesis generation ( Hypothesis generation (
Appetitive function Explorative or goal-directed behavior (
Association learning learning process in which two or more items or concepts become associated with each other; often used in relation to learned stimulus-response associations
Auditory discrimination function Auditory discrimination is the ability to detect differences in phonemes (the smallest unit of sound in a language), including the ability to identify words and sounds that are similar and those that are different ( Auditory discrimination
tone discrimination
Auditory system function process whereby auditory stimuli are selected, organized and interpreted by the organism. (CSP)
Autonomic nervous system function The autonomic nervous system is a key system that helps to maintain homeostasis and adaptation throughout the human body. It consists of both central and peripheral components that provide thermoregulation, arterial blood pressure adaptation, as well as alterations in regional blood flow in response to metabolic demands, micturition, gastrointestinal motility, and sexual function (
Behavioral system function
Cognitive function * Level of functioning in intellectual tasks. (PSY) * Ability to perform cognitive activity (observable entity)
Communication function
Deductive reasoning function Deductive reasoning is the process of using general premises to ascertain specific conclusions ( Syllogism (
Discrimination function
Gustatory learning The formation of a knowledge representation that contains information about gustatory percepts.
Gustatory system function * Taste; the faculty of taste, distinguishing substances by means of the taste buds. (NCI) * The sensation or perception of certain qualities of substances put in the mouth, primarily sweet, sour, salt and bitter. (MSH) * The series of events required for an organism to receive a gustatory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Gustation involves the direct detection of chemical composition, usually through contact with chemoreceptor cells. (GO:ai, (GO) * sense effected by the gustatory receptors in the tongue; primarily sweet, sour, salty and bitter. (CSP) Taste system function
Habituation A decrease in a behavioral response to a repeated stimulus. This is exemplified by the failure of a person to show a startle response to a loud noise that has been repeatedly presented. (source: ISBN:0582227089)
Inductive reasoning function Inductive reasoning is the process of inferring general principles from specific observations ( Induction (
Kinesthetic system function Provides for the sense of body position and movement (limb and joint position). (CSP)
Learning Learning is the process of procuring novel information or knowledge by systematic study or trial and error (
Locomotor function Locomotion is a sophisticated motor behavior needed by animals and humans to move through the environment. All types of locomotion, including swimming, flying, walking, running, and hopping, are repetitive motor activities that require the activation of the limb and body muscles in an organized rhythm and pattern (
Motor system function The motor system is the system involved in the production and control of voluntary and reflex movements (
Nutrition function Nourishment of the body with balanced food in a manner that energy, maintenance, and growth processes occur. (OMS)
Oculomotor function The oculomotor system consists of six extraocular muscles attached to the orbit and to the eyeball, extraocular motor neurons located in three different brainstem motor nuclei, and premotor centers and circuits involved in the generation and control of the different types of eye movement. Its exact functional design and robust biomechanics have allowed this motor system to survive, almost unchanged, across different trends in vertebrate evolution ( Eye movement system
vestibular-ocular reflex system (
Olfactory system function The olfactory system in most vertebrate species consists of two distinct subsystems: the main olfactory system and the accessory olfactory system. The main olfactory system is generally considered to be important in the detection and processing of airborne chemicals whereas the accessory olfactory system is mainly used in the detection and processing of water-soluble chemicals (
Parasympathetic nervous system function
Proprioceptive system function
Reasoning function Reasoning is the cognitive ability to infer that something must be true, or is likely to be true, given that the known information is true (
Reinforcement Learning In neural modeling, a learning method where a neural network changes based on a positive or negative reward. The reward is an input to the network which depends on the model's behavior as it explores a solution space.
Relational learning learning to differentiate among stimuli on the basis of relational properties (e.g., the larger of two stimuli) rather than absolute properties (e.g., the stimulus that has a given size).
Rule learning process in which a participant gradually acquires knowledge about a fixed but unstated standard that defines, for example, the acceptability of a response or membership of category
Saccade A fast movement of an eye, head or other part of an animal's body
Sensory system function Sensory systems provide signals for regulatory systems, and at higher levels, they serve to produce sensations and perceptions (
Sequence learning learning of a sequence of items or responses in the precise order of their presentation.
Skeletomotor reflex function
Skill learning learning to perform a task with proficiency, as defined by ease, speed, and accuracy of performance, acquired through a high degree of practice.
Somatosensory system function The somatosensory system is a part of the nervous system that detects and allows for perception of the modalities (sense) of pain, temperature, head and body position (called proprioception), head and body movement (called kinesthesia), and touch (
Sympathetic nervous system function
Unsupervised Learning Approaches for organizing data where the learner is given only unlabeled examples.
Verbal function
Vestibular system function The vestibular system detects motion and position of the head in space. It utilizes this information to regulate postural reflexes and control movement (
Visual system function The human visual system consists of a complex collection of structures that transforms light into a rich palette of visual information that one experiences as the physical environment around us (
