Broen and Storms have developed a theory that attributes schizophrenic cognitive deficit to the combination of high drive levels and low response strength ceiling. The authors tested four hypotheses drawn from the theory in a multiple-choice paired associates learning study (N = 90). The hypotheses were that schizophrenics would demonstrate faster acquisition of reinforced (dominant) responses, lower peak performances, and greater declines in post-peak performance than would two comparison groups. They also hypothesized that all three groups would manifest declines in number of dominant responses after peak performance levels were reached. None of the hypotheses was supported. These results, and the majority of the earlier research on the Broen-Storms hypothesis, cast doubt on the utility of the theory.
布伦和斯托姆斯提出了一种理论，将精神分裂症的认知缺陷归因于高驱力水平和低反应强度上限的结合。作者在一项多项选择配对联想学习研究（N = 90）中检验了从该理论得出的四个假设。这些假设是，与两个对照组相比，精神分裂症患者在强化（优势）反应的习得速度上会更快，峰值表现更低，且峰值后表现的下降幅度更大。他们还假设，在达到峰值表现水平后，所有三组在优势反应数量上都会出现下降。没有一个假设得到支持。这些结果，以及早期对布伦 - 斯托姆斯假设的大多数研究，都对该理论的效用提出了质疑。
