鉴于摇头丸（3，4-亚甲二氧基甲基苯丙胺）或摇头丸的法律的地位，有时很难与参与者面对面接触。接触更多的参与者显然是可取的。本研究使用基于网络的设计访问了更大的样本量。开发了一个网站，用于收集数据。前瞻性记忆能力采用前瞻性记忆问卷进行评估。使用日常记忆问卷调查了日常记忆表现的自我报告。药物调查问卷评估了其他物质以及Ecketamine的使用，允许回归设计以隔离每种物质对认知测量的任何差异的贡献。初步调查结果（N= 488）表明，有一个明显的双重分离之间的影响，摇头丸和大麻。我们发现大麻与短期和内部线索前瞻性记忆中的“此时此地”认知问题有关。相比之下，Eccurrence与长期记忆问题的报告有关，这与存储和检索困难更相关。版权所有（C）2001约翰威利父子有限公司
Given the legal status of MDMA (3,4-methylenedioxymethamphetamine), or Ecstasy, face-to-face access to participants is sometimes difficult, The number of participants in studies of cognitive performance amongst Ecstasy users is variable, with the average being around 30. Access to a larger number of participants is clearly desirable. The present investigation accessed a larger sample size using a web-based design. A website was developed and used for data collection. Prospective memory ability was assessed using the Prospective Memory Questionnaire. Self-report of day-to-day memory performance was investigated using the Everyday Memory Questionnaire. The Drug Questionnaire assessed the use of other substances as well as Ecstasy, allowing a regression design to isolate the contribution of each substance to any variance on the cognitive measures. Preliminary findings (N= 488) indicate that there is a clear double dissociation between the impact of Ecstasy and cannabis. We found that cannabis was associated with reports of 'here-and-now' cognitive problems in short-term and internally cued prospective memory. In contrast, Ecstasy was associated with reports of long-term memory problems, which were more related to storage and retrieval difficulties. Copyright (C) 2001 John Wiley & Sons, Ltd.
