OBJECTIVE The Miranda v. Arizona (1966) decision was intended to protect individuals' rights in custodial situations. The purpose of this paper was to evaluate Miranda abilities of individuals with intellectual disability and evaluate the utility of intelligence in predicting these abilities. Additionally, we aimed to provide an updated resource for forensic examiners regarding the performance of individuals with intellectual disability on the Standardized Assessment of Miranda Abilities (SAMA). HYPOTHESES We hypothesized that IQ, particularly verbal intelligence and working memory, would significantly predict abilities related to recall, vocabulary, knowledge, and acquiescence in a sample with intellectual disability. METHOD Sixty-two individuals diagnosed with intellectual disability completed the Wechsler Adult Intelligence Scale-4th ed. (WAIS-IV), the SAMA, and a background questionnaire. RESULTS Participants demonstrated significantly worse Miranda abilities when compared to the normative sample of the SAMA apart from acquiescence, which they demonstrated at significantly higher rates. Participants exhibited limited existing knowledge of Miranda rights and showed minimal improvement following exposure to a Miranda warning. Verbal abilities were a significant predictor of recall and vocabulary abilities with large effect sizes on average (i.e., ds > 1). IQ was not predictive of misconceptions about Miranda or acquiescence. CONCLUSIONS Verbal intelligence was an important contributor to understanding Miranda. This study provided data related to performance on the SAMA by a sample of individuals with intellectual disability. It may serve as a reference for evaluators, legal professionals, and law enforcement officers when working with justice-involved persons with suspected intellectual disability.

智力的预测能力：智障人士的米兰达能力。

目的Miranda诉Arizona案（1966年）的判决旨在保护在羁押情况下的个人权利。本文的目的是评估智障人士的米兰达能力，并评估智力在预测这些能力方面的效用。此外，我们旨在为法医提供有关智障人士在米兰达能力标准评估（SAMA）方面的表现的最新资源。假设我们假设智商，特别是言语智力和工作记忆，将显着预测与智障样本中的回忆，词汇，知识和默许相关的能力。方法62名被诊断为智力残疾的人完成了Wechsler成人智力量表第4版。（WAIS-IV），SAMA和背景调查表。结果与默认的SAMA样本相比，参与者表现出的Miranda功能明显较差，他们的默示率明显更高。参与者对Miranda权利的了解有限，在暴露于Miranda警告之后，他们的进步很小。言语能力是回忆和词汇能力的重要预测指标，平均而言，其影响大小较大（即ds> 1）。智商不能预测对米兰达或默许的误解。结论言语智力是理解米兰达的重要因素。这项研究提供了与智障人士样本有关的SAMA表现的数据。它可以作为评估者的参考，法律专业人员和执法人员在与涉嫌患有智力障碍的司法相关人员合作时。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。
