本文提出并测试了一个正式的认知模型的去/不去的歧视任务。在这项任务中，执行者选择是否对刺激做出反应，并因对某些刺激做出反应而获得奖励，并因对其他刺激做出反应而受到惩罚。三个认知模型进行了评估的基础上，从纵向研究涉及400名青少年的数据。结果表明，假设参与者能够区分线索的线索依赖模型是最准确和最简约的。该模型有3个参数，分别表示奖励和惩罚对评价的相对影响、学习到或有收益的比率以及学习和响应之间的一致性。佣金错误与奖励的关注度增加有关;遗漏错误与惩罚的关注度增加有关。这两种错误类型都与低选择一致性有关。参数也被证明具有外部效度：注意奖励与Achenbach量表上的外化行为问题相关，选择一致性与低威尔士焦虑相关。因此，本模型可以潜在地提高任务对临床人群之间差异的敏感性。
This article proposes and tests a formal cognitive model for the go/no-go discrimination task. In this task, the performer chooses whether to respond to stimuli and receives rewards for responding to certain stimuli and punishments for responding to others. Three cognitive models were evaluated on the basis of data from a longitudinal study involving 400 adolescents. The results show that a cue-dependent model presupposing that participants can differentiate between cues was the most accurate and parsimonious. This model has 3 parameters denoting the relative impact of rewards and punishments on evaluations, the rate that contingent payoffs are learned, and the consistency between learning and responding. Commission errors were associated with increased attention to rewards; omission errors were associated with increased attention to punishments. Both error types were associated with low choice consistency. The parameters were also shown to have external validity: Attention to rewards was associated with externalizing behavior problems on the Achenbach scale, and choice consistency was associated with low Welsh anxiety. The present model can thus potentially improve the sensitivity of the task to differences between clinical populations.
