口渴的雄性大鼠被给予糖精水，然后延迟患病。在延迟期间，一些大鼠被暴露在旨在刺激其外部系统(即处理外部事件的系统，如听觉和触觉刺激)的事件中。接近雌性，轻微的足部电击，以及高渗盐水注射带来的疼痛，都不会干扰味觉厌恶的获得或消退。事实上，当在腹膜内注射高渗盐水时，会略微增加厌恶情绪的强度。暴露在高温下，改变了皮肤温度和核心温度，略微减弱了厌恶情绪的形成。总体而言，这些结果强调了内部系统(即处理味道、疾病和核心温度等内部事件的系统)和外部系统的独立性。此外，与内部系统相关的事件的关联不容易受到与外部系统相关的事件的干扰。
Thirsty male rats were given saccharin water followed by delayed illness. During the delay, some of the rats were exposed to events designed to stimulate their external systems (i.e., the system that processes external events such as auditory and tactile stimulation). Access to females, mild footshocks, and pain from hypertonic saline injections did not interfere with either the acquisition or extinction of a taste aversion. In fact, when administered intraperitoneally, the hypertonic saline slightly increased the strength of the aversion. Exposure to heat, which changed both skin temperature and core temperature, slightly attenuated the formation of the aversion. Overall, these results emphasize the independence of the internal system (i.e., the system that deals with internal events such as taste, illness, and core temperature) and the external system. Furthermore, the associating of events related to the internal system is not readily interfered with by events related to the external system.
