CHAIN: A complex behavior consisting of two or more response segments that
occur in a definite order. A chain can
be homogeneous or heterogeneous. Homogeneous chains consist of responses that are similar to one
another, as in lifting or throwing. Heterogeneous chains consist of responses that differ from one
another, as in playing football or assembling a barbecue. 20 |

CHAIN: A sequence of discriminated operants such that responses during one
stimulus are followed by other stimuli that reinforce those
responses and set the occasion for subsequent ones (see
CHAINED SCHEDULE, CONDITIONED
REINFORCER). Not all temporally integrated sequences are maintained
through chaining; those that are not
must be distinguished from those that are. Parts of a chain are variously called components, links, or
members. Procedures for creating chains
often start with responses at the ends of the sequence, closest to
the reinforcer, and then work back (backward chaining); starting from the other end (forward
chaining) is more difficult, because
early responses may extinguish while later ones are being shaped.
Chains with topographically sin-dlar
responses are homogeneous (e.g., a pigeon's pecks in a chained schedule); those with topographically
dissimilar responses are heterogeneous (e.g., a sequence consisting
of alley-running, lever-pressing, and moving to a feeder). |

CHAIN: A chain consists of two or more
performances linked by common stimuli. One performance produces the
conditions which make the next possible. The stimulus linking the
two performances serves both as a conditioned reinforcer
maintaining the topography and frequency of the first performance,
and as a stimulus setting the occasion for the second. |

CHAIN: is the most commonly used term for "stimulus/response chain." |
