Add to ORKGPrevious research revealed that rats making responses in running wheels displayed changes in risk-sensitivity when effort is manipulated. However, research has not examined the effects of effort on choice when using a lever-press response. We used a within-subjects design to explore rats\u27 (n = 10) preference for variable or fixed reward options as effort required to press a lever increased. Effort was increased each lever from 10 g to 70 g. We hypothesized that rats would favor the variable option as effort increased. Although, the data did not reveal that rats\u27 choices were significantly altered due to the effort conditions
