What is the influence of emotion on memory?4 answersEmotion has a significant influence on memory. It has been found that emotion enhances memory for individual items but weakens memory for associations between items. Emotional stimuli capture attention, leading to enhanced encoding of the emotional item but reduced encoding of the surrounding environment. This selective attention to emotional information impairs associative memory. However, the effects of emotion on memory may differ depending on the type of emotion. Positive emotion has been shown to enhance association-memory, while negative emotion typically impairs it. Positive emotion can lead to better memory for associations between positive words, but not for pairings of positive and neutral words. These findings suggest that valence, as well as arousal, should be considered when examining the influence of emotion on memory.
Why the memory without stray fields is good?5 answersA memory without stray fields is desirable because it improves the electrical and retention performance of the memory stack by reducing switching asymmetry in the free layer. It also improves the performance of a filter layer by reducing asymmetry in the dynamic magnetic rotation of that layer. Stray magnetic fields in magnetic memory devices can lead to natural asymmetry in magnetic properties, which is undesirable for magnetic random access memory applications. Edge effects dominate the overall stray magnetic field in patterned devices, and a conventional synthetic antiferromagnet structure is only partially able to compensate for the field at the free layer position. Therefore, reducing stray magnetic fields is crucial for achieving optimal performance in magnetic memory devices.
