The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information. [1] [2] Stimuli, like stress, improved memory when it was related to learning the subject. [3] During times of stress, the body reacts by secreting stress hormones into the bloodstream.
The activity in the amygdala is part of the episodic memory that was being created due to the adverse stimuli. [10] Most recently, an intracranial EEG study found that the amygdala triggered more pronounced hippocampal sharp-wave ripples after the encoding of more arousing experiences, which are believed to play a critical role in memory ...
Liking refers to the palatability or taste of the food, which is reduced by repeated consumption. Wanting is the motivation to consume the food, which is also reduced by repeated consumption of a food [11] [12] and may be due to change in memory-related processes. [13] Wanting can be triggered by a variety of psychological processes.

The reaction of these systems causes a number of physical changes that have both short- and long-term effects on the body. [19] The Holmes and Rahe stress scale was developed as a method of assessing the risk of disease from life changes. [20] The scale lists both positive and negative changes that elicit stress.
Due to their age, children have relatively undeveloped coping skills. [79] For this reason a stressful event may cause some changes in their behavior. Falling in with a new crowd, developing some new and sometimes undesirable habits are just some of the changes stress may trigger in their lives. [77]
Sensory information is stored in sensory memory just long enough to be transferred to short-term memory. [1] Humans have five traditional senses: sight, hearing, taste, smell, touch. Sensory memory (SM) allows individuals to retain impressions of sensory information after the original stimulus has ceased. [2]
Human models illustrating transgenerational stress effects are limited due to relatively novel exploration of the topic of epigenetics as well as lengthy follow-up intervals required for multi-generational studies. Several models, however, have investigated the role of epigenetic inheritance and transgenerational stress effects.
