Key pecking of pigeons was reinforced with grain on a progressive ratio schedule during the presence of either of two key colors. Under one color, all responses were shocked; under the other color, responses were not shocked. A single response on a second key switched the key color and reset the progressive ratio, provided that the first step of the progressive ratio had been completed. A preference developed for the longer ratios of the progressive ratio under the non‐shock key color. When the severity of punishment suppressed responding under the key color correlated with shock, the subjects continued to switch to the shock condition after a moderate degree of responding under the non‐shock condition. Severe punishment also resulted in frequent, ineffective responses on the switching key and extended pausing under the key color associated with shock.
