[Marvel] If Gamma radiation experiments found emotions trigger various powers, what emotion would be connected to what kind of power?

It seems that it would likely break down like this:

Anger/rage = physical strength.  Obviously anger and rage stifle mental might and manifest via physical acts of aggression.  

Calm/serenity = clairvoyance.  Via calmness the mind would be more open to suggestion and interpretations.  This would allow for access to otherwise untapped mental powers that would become more accessible and powerful the calmer the person became.

Mirth/hilarity/joy = material manipulation.  The active imagination when tapped into whatever forces exist in the universe would likely be able to bend the physical bounds of reality closer to their will.  Maybe it would be defying gravity or walking through a wall or simply bending an otherwise solid object to change its shape...  The ability to not only imagine new things but draw pure happiness from their creation would be a powerful force for creation and manipulation of the physical realm.

Sadness/despair - Likely some sort of temporal manipulation that would not allow for full time travel and or possible teleportation.  Sadness is usually rooted in past experience or desire to be elsewhere and so there would likely be a strong desire to influence time and space like that but the rules of cause and effect of temporal manipulation would state that regardless their actions they would not be able to change whatever events took place to set them on their course.  

Frisson - this one would actually be very dangerous.  Because frisson is any strong emotional reaction to a specific stimuli it would likely be a manifestation of the powers associated with the emotion closest to the source of frisson.  Impossible to predict or count on and likely enhanced by the use of drugs.

In fact under these conditions that emotions would trigger certain powers drugs like cannabis, heroin, lsd, cocaine, ecstasy and such would likely become trigger mechanisms for their respective powers if the appropriate stimuli was not available but the need was there.
