The only thing that seems more obvious is introversion.
You were talking about feelers...not sure if you are aware, but the Fe/Fi functions has more to do with values than emotion. For example, INFJ's and INTP's are interested in harmonious group dynamics but it's quite a 'cold' function as it's not really interested in individuals. Fi is quite self-centered and thus equally 'cold'.
Emotions however...all types can be equally emotional, it's just that the T-types prefer to filter their emotion through thinking, hence their 'robotic' appearance.
