length ratio in males has been found to be related to certain psychological test 
scores, especially physical aggression. That relationship between the second and 
fourth fingers, reflecting early prenatal conditions, is believed to be an even better 
predictor of physical aggression than a males current adult level of testosterone. The 
finger ratio, however, did not predict anger, hostility, or verbal aggression, only 
physical aggression. Likewise, finger length ratio in women does not correlate with 
any of these anger measures (Bailey & Hurd, 2005). Please note: The relationships 
found in this study based on about 140 subjects are not strong and reliable enough 
to be used to make individual predictions of physical aggressiveness using a persons 
index finger being shorter relative to his ring finger. Yet, this is an amazing finding 
indicating the distant but important early prenatal influence on adult personality 
traits. This measure is just one small factor influencing physical aggression. Such a 
finding should remind us to not expect human behavior to be simple and easy to 
understand. 
Definition of Terms 
We will study more about how anger develops. Is it innate? Certainly most 
three-year-olds can throw a temper tantrum without any formal training and 
often even without observing a model. Is it learned? Why are the abused 
sometimes abusers? Does having a temper and being aggressive yield 
payoffs? You bet. How do we learn to suppress aggression? How can we learn 
to forgive others?  
Anger can be the result of hurt pride, of unreasonable expectations, or of 
repeated hostile fantasies. Besides getting our way, we may unconsciously 
use anger to blame others for our own shortcomings, to justify oppressing 
others, to boost our own sagging egos, to conceal other feelings, and to 
handle other emotions (as when we become aggressive when we are afraid). 
Any situation that frustrates us, especially when we think someone else is to 
blame for our loss, is a potential trigger for anger and aggression.  
So, what is frustration? It is the feeling we get when we don't get what 
we want, when something interferes with our gaining a desired and expected 
goal. It can be physical (a flat tire), our own limitations (paralysis after an 
accident), our choices (an unprepared for and flunked exam), others' actions 
(parental restrictions or torturing a political prisoner), others' motives 
(deception for a self-serving purpose), or society's injustice (born into poverty 
and finding no way out).  
Anger is feeling mad in response to frustration or injury. You don't like 
what has happened and usually you'd like to get revenge. Anger is an 
emotional-physiological-cognitive internal state; it is separate from the 
behavior it might prompt. In some instances, angry emotions are beneficial; if 
we are being taken advantage of, anger motivates us to take action (not 
necessarily aggressive) to correct the situation. Aggression is action, i.e. 
attacking someone or a group. It is intended to harm someone. It can be a 
verbal attack--insults, threats, sarcasm, or attributing nasty motives to them-
-or a physical punishment or restriction. What about thoughts and fantasies in 
which we humiliate or brutally assault our enemies? Is that aggression? What 
about violent dreams? Such thoughts and dreams suggest anger, of course, 
but are not aggression as I have defined it here.
