可卡因依赖在美国是一个特别严重的问题，造成广泛的经济和个人损失。有重要的证据表明，普遍认知缺陷与可卡因依赖有关。两项研究评估了上下文处理（涉及表征和维持与环境有关的信息的过程）是否可能被视为一种特定过程的缺陷，这可能解释了与可卡因依赖相关的更广泛的认知缺陷的某些方面。研究1使用AX任务的期望变体来评估这种能力；研究2采用点模式期望任务。在每个研究中，在d ' context， AX命中和BX未命中的比较中，发现组间差异显著；结果表明，两组之间在语境处理能力上存在显著差异。在研究1中，实验组与BX组的显著先验对比表明，可卡因组可能存在特定的语境加工缺陷；然而，在研究2中，这种对比并不显著。总的来说，这些研究的结果支持了情境处理能力受损与可卡因滥用有关的理论。然而，这些结果并不能解释上下文处理能力中特定过程的缺陷。未来的研究目标是调查与可卡因滥用有关的这种情境处理障碍的各个方面，可以阐明这种缺陷的特异性。（PsycINFO数据库记录(c) 2016 APA，版权所有）
Cocaine dependence is a particularly severe problem in the United States, resulting in broad economic and personal costs. Significant evidence of generalized cognitive deficits associated with cocaine dependence has been reported. Two studies evaluated whether context processing, the processes involved in representing and maintaining information regarding the context of one’s environment, might be seen as a process-specific deficit that may explain some aspects of the broader cognitive deficits associated with cocaine dependence. Study 1 used the expectancy variant of the AX task to assess this ability; Study 2 employed the Dot Pattern Expectancy task. Significant between-groups differences were found in each study for d′-context, a comparison of AX hits and BX misses; these results indicated significant between-groups differences in context-processing ability. In Study 1, significant between-groups a priori contrasts of AY versus BX trials indicated the likelihood of a specific deficit in context processing in the cocaine group; however, this contrast was not significant in Study 2. Overall, the results of these studies support the theory of impaired context-processing ability associated with cocaine misuse. However, these results do not allow for the interpretation of a process-specific deficit in context-processing ability. Future research targeted at investigating aspects of this context-processing impairment associated with cocaine misuse can shed light on the specificity of this deficit.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
