Brief article from THT about anxiety in baseball. As someone that studied psychology, I enjoy this line of thinking. Though the article itself somewhat common sense in that area, I still enjoy seeing it.
To elaborate further on this topic:
a) If team chemistry has an effect, here is one of the places it could affect actual performance. A player that feels supported will be less likely to suffer from over-anxiety, and I do not think it is a stretch to believe that most players get overanxious at some point during the season. Ergo, if the player feels supported, perhaps it increases the likelihood that the player will "Over perform" (due to natural over-anxiousness being an inherent part of most talent evaluation methods).
b) Though we do not often talk about psychology in baseball, we do talk about how players are angry, requiring changes of scenery, etc., and that these appear to affect their performance. Someday I hope to see more psychotherapists working directly with baseball teams, but that may be my own preference.
Thoughts on anything?
