Abstract

This study examined the correspondence between preference for systematically differing magnitudes of edible stimuli and relative progressive ratio (PR) breakpoints. A primary MSWO preference assessment was used to rank eight different edible items. Next, a secondary MSWO preference assessment determined preference for 0.5, 2, and 10 g of HP and LP items. Following a baseline phase, 0.5, 2, and 10 g of both the HP and LP items (i.e., six stimuli total) were tested individually under PR reinforcer assessment administrations. In contrast to previous research, there was not a direct correspondence between preference and PR breakpoints. In addition, HP stimuli did not consistently produce higher breakpoints when compared to LP stimuli, irrespective of magnitude.
