Many theorists propose two types of processing: heuristic and analytic. In conflict tasks, in which these processing types lead to opposing responses, giving the analytic response may require both detection and resolution of the conflict. The ratio bias task, in which people tend to treat larger numbered ratios (e.g., 20/100) as indicating a higher likelihood of winning than do equivalent smaller numbered ratios (e.g., 2/10), is considered to induce such a conflict. Experiment 1 showed response time differences associated with conflict detection, resolution, and the amount of conflict induced. The conflict detection and resolution effects were replicated in Experiment 2 and were not affected by decreasing the influence of the heuristic response or decreasing the capacity to make the analytic response. The results are consistent with dual-process accounts, but a single-process account in which quantitative, rather than qualitative, differences in processing are assumed fares equally well in explaining the data.
启发式和分析式。在冲突任务中，这两种加工类型会导致相反的反应，给出分析式反应可能既需要检测又需要解决冲突。比率偏差任务，即人们倾向于认为较大数字的比率（例如，20/100）比等效的较小数字的比率（例如，2/10）表示更高的获胜可能性，被认为会引起这种冲突。实验 1 显示了与冲突检测、解决以及冲突诱导量相关的反应时差异。在实验 2 中复制了冲突检测和解决效应，并且不受降低启发式反应影响或降低进行分析式反应能力的影响。结果与双加工理论一致，但假设在加工中存在定量而不是定性差异的单一加工理论同样可以很好地解释数据。
