As a direct consequence, stress (especially uncontrollable stressors) impairs various forms of memory. However, not all memories suffer this effect, and the chapter seeks to explain this point by arguing that the experience of stress (through its impact on the hippocampus) causes stressful events to be recorded in a" fragmented" manner, with the elements of the event not woven into a coherent remembered episode.
