Increasingly, people are beginning to realize that asking how much heredity or environment influence a particular trait is not the right approach. The reality is that there is not a simple way to disentangle the multitude of forces that exist. These influences include genetic factors that interact with one another, environmental factors that interact such as social experiences and overall culture, as well as how both hereditary and environmental influences intermingle. Instead, many researchers today are interested in seeing how genes modulate environmental influences and vice versa.
@Barbara – I think it’s a piece of the puzzle. It might be as simple as pain and pleasure. Feeling pleasure from what you’re strong at, and pain from what you’re not. I’ve found that some people are more about getting out of pain, while others are more about moving towards pleasure. I think this is potentially linked to “learned helplessness.” I find learned helplessness shuts people down from pursuiting pleasure and instead, avoiding pain. I think focus is also governed by where you are in Maslow’s hiearchy (below the line or above the line … or surviving vs. thriving.)
