I asked Google Bard to elaborate on what you mean, and the response I received was interesting. I thought I would put it here so others can read it.

Sure. The statement "Emotions may therefore be triggered and not perceived or perception altered due to various reasons eg. trauma, medication etc" means that our emotions can be triggered by events or experiences, but we may not always be aware of these triggers. This can be due to a variety of reasons, such as trauma, medication, or other factors.

For example, someone who has experienced trauma may have a strong emotional reaction to a seemingly innocuous event. This is because the trauma has caused them to develop a heightened sense of fear or anxiety. As a result, they may be triggered by things that remind them of the trauma, even if they are not consciously aware of the connection.

Medication can also alter our perception of emotions. For example, some antidepressants can cause people to feel numb or emotionally detached. This is because the medication is blocking the production of certain neurotransmitters that are involved in emotion.

In addition to trauma and medication, there are a number of other factors that can alter our perception of emotions. These include:

* Stress

* Fatigue

* Illness

* Substance abuse

* Head injuries

* Personality disorders

If you are experiencing difficulty understanding or managing your emotions, it is important to seek professional help. A therapist can help you to identify the triggers for your emotions and develop coping mechanisms to deal with them.
