Zarcone, Troy J.; Chen, Rong; Fowler, Stephen C. – Journal of the Experimental Analysis of Behavior, 2009
The effect of force requirements on response effort was examined using inbred C57BL/6J mice trained to press a disk with their snout. Lateral peak forces greater than 2 g were defined as responses (i.e., all responses above the measurement threshold). Different, higher force requirements were used to define criterion responses (a subclass of all…

Bacha-Mendez, Gustavo; Reid, Alliston K.; Mendoza-Soylovna, Adela – Journal of the Experimental Analysis of Behavior, 2007
Two experiments with rats examined the dynamics of well-learned response sequences when reinforcement contingencies were changed. Both experiments contained four phases, each of which reinforced a 2-response sequence of lever presses until responding was stable. The contingencies then were shifted to a new reinforced sequence until responding was…

Wylie, A. Michael; Grosmann, J. A. – Journal of Applied Behavior Analysis, 1988
The study evaluated the effectiveness of superimposition and subsequent removal of a schedule of continuous reinforcement (CRF) as a rate-decreasing procedure in efforts to eliminate unwanted behaviors. Examination of lever-pressing patterns of eight male rats showed responding was substantially reduced during the superimposition of CRF but…

Machado, Armando – Psychological Review, 1997
A dynamic model of how animals learn to regulate their behavior under time-based reinforcement schedules is presented. It assumes serial activation of behavioral states during the inter-reinforcement interval, an associative process linking the states and operant response, and a rule mapping the states onto response rate.
