reciprocal inhibition

1. a technique in behavior therapy that aims to replace an undesired response (e.g., anxiety) with a desired one by counterconditioning. It relies on the gradual substitution of a response that is incompatible with the original one and is potent enough to neutralize the anxiety-evoking power of the stimulus. See also systematic desensitization. [devised by Joseph Wolpe]

2. in neuroscience, the inhibition of one spinal reflex when another is elicited. [proposed by Charles Scott Sherrington]

3. a neural mechanism that prevents opposing muscles from contracting at the same time.

4. the inability to recall two associated ideas or items because of their interference with each other.

emergent feature

an entity produced by the interaction of small or simple elements (e.g., short line segments) in the visual system, such an entity (e.g., a polygon) being more salient to human perception than are the elements themselves. In ergonomics, object displays are usually designed to make use of emergent features; the display configurations yield an overall image (e.g., a rectangle or pentagon) that can be perceived holistically by the operator of a machine system and therefore rapidly analyzed to assess the state of the system. When a component of the system is not in the appropriate or normal state, the image will be distorted, alerting the operator to potential problems.
