The relationships between executive processes, associative learning and different aspects of real world memory functioning were explored in a sample of cannabis users and nonusers. Measures of executive component processes, associative learning, everyday memory, prospective memory, and cognitive failures were administered. Relative to nonusers, cannabis users were found to be impaired in several aspects of real world memory functioning. No other group differences were apparent. The absence of cannabis related deficits in those executive component processes and aspects of learning that are believed to support real world memory processes is surprising given that cannabis related deficits were obtained in real world memory. The present results are discussed within the context of neuroimaging evidence which suggests that cannabis users may exhibit different patterns of neural activation when performing executive tasks while not always exhibiting deficits on these tasks.
在一组大麻使用者和非使用者样本中，研究了执行过程、联想学习与现实世界记忆功能不同方面之间的关系。对执行成分过程、联想学习、日常记忆、前瞻性记忆和认知失误进行了测量。与非使用者相比，发现大麻使用者在现实世界记忆功能的几个方面存在损害。没有其他明显的组间差异。鉴于在现实世界记忆中发现了与大麻相关的缺陷，而在那些被认为支持现实世界记忆过程的执行成分过程和学习方面却没有与大麻相关的缺陷，这一现象令人惊讶。本文结果在神经影像学证据的背景下进行了讨论，该证据表明大麻使用者在执行执行任务时可能表现出不同的神经激活模式，但在这些任务上并不总是表现出缺陷。
