思维散乱

思维散乱是一种以运用系统化、逻辑化的思维过程来分析和归类概念信息的能力显著下降为特征的状态。它最常在重度剂量的致幻和镇静类物质作用下被诱发,例如解离剂、迷幻剂、大麻素以及GABA能物质。

思维散乱是一种状态,指人运用系统化、逻辑化的思维过程来分析和归类概念信息的能力显著下降。它似乎通过增加与当前主题无关或不相关的想法而发生,从而降低了人进行结构化、连贯思维流的能力。这一效应似乎还使用户在思维链中能够保持的相关信息量显著减少,而这些信息本可用于长时间的心算、阐述观点和分析逻辑论证。

思维散乱常伴随其他同时出现的效应,例如分析能力抑制和思维加速。它最常在重度剂量的致幻和镇静类物质作用下被诱发,例如解离剂1234、迷幻剂15、大麻素167以及GABA能物质89。然而值得注意的是,某些兴奋剂或益智药化合物在较低剂量下可诱发思维条理化,但在较高剂量下也常会产生相反的思维散乱效应。191011
