A reflex circle is sensory information effecting motor behavior that effects sensory information. An action is its effect on the environment. (cbb 12/87)

The visual system has a major effect on our interpretation of physical movement. For example, subjects think they are walking backward when given the perceptional clues of walking backwards.

The Gibsonian approach attempts to make a theory of coordination out of reflexes, or more accurately out of environmental variables that determine the success and progress of a movement.

Reflexes can effect and be effected by any part of the nervous system. This adaptability is remarkable.

Artificial reflexes may assist with use an artificial leg. (cbb 5/94)

Subtopic: reflex ring or circle up

Quote: reflex ring: performance of purposeful movement requires continuous sensing of the effect of movement [»pickL_1984]
Quote: the coordination reflex is more a closed circle than a sensory reflex arc [»bernN_1940]

Subtopic: meaning depends on effect up

Quote: the work of the central nervous system may depend on the locomotive system; i.e., intelligence derived from locomotion [»dreyHL_1979]
Quote: message-passing semantics: meaning of a message depends on its effect on subsequent behavior [»hewiC4_1985]
Quote: an adaptive organism must correlate the world of processes with the sensed world [»simoHA_1981]

Subtopic: motor action relative to effect up

Quote: specificity of muscular action lies in meaningful changes to the environment instead of the pattern of movements [»reedES_1984]
Quote: a motor act is the change effected on an environment instead of the mechanism or motions leading to the change [»reedES_1984]
Quote: motor system is responsive to the visual framework, e.g., moving the walls around an infant causes a fall [»trevC_1984]
Quote: humans walking forward will report the reverse if the world looks like it is going backwards [»turvMT_1984]

Subtopic: affordance up

Quote: an affordance is an invariant arrangement of surface/substance properties that permits a given animal a particular activity; e.g., falling, climbing [»turvMT_1984]
Quote: the Gibsonian program seeks to uncover natural, lawful basis for distinguishing jumpable objects, step-down places, etc.; e.g., velocity ratio [»turvMT_1984]
Quote: a biological system can achieve a stable equilibrium without comparing actual with desired values; under circular causality finds intersection of two functions [»turvMT_1984]
Quote: the Gibsonian program replaces a teleological description with a circular causality between action and its affects; e.g., optical flow [»turvMT_1984]
Quote: the inverse rate of dialation of a bounded region specifies time of contact [»turvMT_1984]
Quote: subjects can accurately predict climbability of stairs [»turvMT_1984]

Subtopic: natural reflex arc up

Quote: artificial reflex arc by pattern matching of sensory data [»bekeGA4_1986]
Quote: an organic reflex can be invoked by any perceptible stimulus, hormonal process, or cell metabolism; remarkable adaptability [»bernN_1957]
Quote: reflex arc from exteroceptive and proprioceptive sensors to motion sequences at the joint [»bekeGA4_1986]
Quote: artificial knee with automatic knee locking reflex on contact with ground [»bekeGA4_1986]
Quote: with one artificial knee can compare external reflex control with normal reflex control
