But their behaviour can have far-reaching consequences. Families and friends can be the targets of alcohol-fuelled outbursts, as can other unsuspecting members of the public. For Caldicott, who regularly sees the results of alcohol-related violence, personality is a key element that separates aggressive drunks from everyone else.
People who are more irritable, have poorer anger control, and who display lower levels of empathy towards others when sober, are more likely to be aggressive when they have alcohol in their system.
Gender also has an influence: Out of control There is increasing evidence that subtle variations in brain function mean some people behave worse than others when they have a few drinks.
Decision-making, problem solving and reasoning are all jobs the executive system takes control of. As Heinz explains, it is like the command centre of the brain, that "tells you when to put on the brakes, think about the consequences, steer yourself towards a better long-term outcome.
Instead of taking a few deep breaths when we feel slighted or insulted, we give in to our impulses, which for some are violent. Importantly, some people naturally have poorer executive control than others, and these people, particularly if they are male, are more likely to be aggressive after drinking alcohol.
A lack of executive control could also help to explain why adolescents and young adults are so frequently the perpetrators of violent behaviour when drunk.
It has been shown that our brains continue to develop well into our 20s and that one of the last parts of the brain to develop is the prefrontal lobe, the region responsible for reigning in impulses through executive control.
People who have a dependence on alcohol have a "double whammy" when it comes to executive control, according to Heinz. Each time they consume alcohol, their executive functioning is impaired due to the alcohol in their system. Studies on rats have shown that, as in humans, only a small proportion of individuals become aggressive when inebriated.
The studies also show that rats with lower levels of the brain signalling chemical serotonin, and higher levels of another called dopamine, are more likely to be aggressive when given alcohol.
Such brain signalling chemicals are known as neurotransmitters. Similar changes in both of these neurotransmitters have been found in chronic alcohol drinkers, and it is believed likely they play a role in violence in non-alcoholic binge drinkers too.

People with lower serotonin levels are also known to be more likely to consume alcohol to the point of excess. Since early life trauma and adversity can alter serotonin signalling, these factors have potential to raise the odds of a person having a short temper when drunk.
Alert and alarmed When someone accidentally bumps into you in a crowded bar or at a sporting event, most of us are able to quickly shrug it off as a benign interruption to our day. But add alcohol to the equation and an innocuous bump can suddenly be interpreted as a serious threat, or even a deliberate act of aggression.
Expectations matter For Heinz, one of the most interesting areas of individual difference when it comes to alcohol-related aggression is in what we expect to happen when we get drunk. Expectations about what behaviour is normal and socially acceptable when alcohol is consumed can be set in place long before we take our first sip of beer.
How our parents act when they drink can lay down our first impression of alcohol-related behaviour. The power of expectation can also play a part in influencing how people behave when they consume different alcoholic drinks, quite apart from the physical impact of differing alcohol concentrations, Heinz believes.
Whether certain drinks, such as those with high levels of sugar or caffeine, help to enhance aggression is unclear, although Heinz notes that alcoholic drinks that contain caffeine can lead people to take more risks than they otherwise would.
Curbing violent behaviour With people who are more likely to be aggressive when they drink, one of the greatest challenges for psychologists like Heinz is teaching temper control. She says that anger management programs are a good start for those who end up seeking help when alcohol gets them into trouble with the law or their families.
But when it comes to reducing the number of people turning up at hospital emergency departments due to alcohol-related violence, Caldicott believes limiting overall community alcohol consumption would be of clear benefit.Hormones, Brain and Behavior, Third Edition offers a state-of-the-art overview of hormonally-mediated behaviors, including an extensive discussion of the effects of hormones on insects, fish, amphibians, birds, rodents, and humans.

Description Antisocial behavior may be overt, involving aggressive actions against siblings, peers, parents, teachers, or other adults, such as verbal abuse, bullying and hitting; or covert, involving aggressive actions against property, such as theft, vandalism, and fire-setting.
Klaus A. Miczek, Joseph F. DeBold, Margaret Haney, Jennifer Tidey, Jeffrey Vivian, Elise M. Weerts. The alcohol-drug abuse-violence nexus presents itself in several distinctly different facets: alcohol and other drugs of abuse may act on brain mechanisms that cause a high-risk individual to engage in aggressive and violent behavior.
