"Probably she sensed a sense of rejection I think is what's going on here. Probably someone refused to listen to her, to understand her, to make sense of the situation and just said 'this is going on for everybody (the fact that thousands of baggage were lost in London Heathrow's Terminal 5). She probably didn't feel heard or understood or validated in some respect and so had this angry outburst to protect herself. Anger is a protective mechanism and can be quite useful at times when it's used effectively but of course becomes a problem when it's too intense or too frequent and leads to aggressive behaviour."

"The interesting irony if you like is to see what she does with this anger herself. If she starts to beat herself about it, the more she's critical about herself, about what's just happened, the more likely she is actually to be angry again in the future. We get a low sense of self-confidence when we are self-critical. It's understandable in the world that she lives in, she's a very successful supermodel, she's determined, it's a very pressurised and critical and competitive environment. Understandably she would be self-critical in order to motivate herself to do the best she can but obviously there's a cost to being so critical which is actually low sense of confidence."

"Obviously we can't discard the impact this sort of environment has on somebody and the competitiveness of it but of course what we know in psychology is the environment is not the problem, it's how we relate to it is or where we could do some work and make a difference so absolutely I think she would do well to go into some sort of anger management programme and I understand that she has in the past but a re-go at that might be a useful thing but obviously it's not just about managing anger, it's important that we talk about anger in the right way when we try to manage it. It's not a bad behaviour because if it's bad we would beat ourself up when we do it so it's about being more accepting of self and being less hard on herself I think."

11. CAMPBELL ON CATWALK

STORY: The 37-year-old was escorted off a U.S.-bound flight on Thursday (April 3) after police were called. She was arrested on suspicion of assaulting a police officer, and later released to return on bail in late May.

A Scotland Yard statement said she was released on bail shortly after midnight, and was due to return on bail.

Campbell was on a British Airways flight due to depart for Los Angeles when the disturbance occurred.

Her spokeswoman said that one of two bags she had checked in had gone missing and that "BA decided to resolve this by insisting she leave the flight and then called the police to forcibly eject her from the flight."

She added that BA failed to give an explanation as to why Campbell's bag went missing at Terminal 5.

Dr. Michael Sinclair, a psychologist specialising in anger management behaviour, offered reasons as to why she may have reacted so erratically at Heathrow Airport.

"Probably she sensed a sense of rejection I think is what's going on here. Probably someone refused to listen to her, to understand her, to make sense of the situation and just said 'this is going on for everybody (the fact that thousands of baggage were lost in London Heathrow's Terminal 5). She probably didn't feel heard or understood or validated in some respect and so had this angry outburst to protect herself. Anger is a protective mechanism and can be quite useful at times when it's used effectively but of course becomes a problem when it's too intense or too frequent and leads to aggressive behaviour," he said.

It is not the first time Campbell has been in trouble with the law.

In 2000, she threw a mobile phone at her assistant and was sent to anger management classes and last year, she spent five days mopping floors as part of a community service sentence in New York after launching a mobile phone at her housekeeper during an argument over a pair of jeans.

Dr. Sinclair said the aftermath of the Heathrow incident will be critical to Campbell and her psyche and it was important to understand the cycle of erratic behaviour.

"The interesting irony if you like is to see what she does with this anger herself. If she starts to beat herself about it, the more she's critical about herself, about what's just happened, the more likely she is actually to be angry again in the future. We get a low sense of self-confidence when we are self-critical. It's understandable in the world that she lives in, she's a very successful supermodel, she's determined, it's a very pressurised and critical and competitive environment. Understandably she would be self-critical in order to motivate herself to do the best she can but obviously there's a cost to being so critical which is actually low sense of confidence," he said.

He added that while her career as one of the world's top supermodels is incredibly demanding, it wasn't fully to blame for her reported outbursts of rage.

"Obviously we can't discard the impact this sort of environment has on somebody and the competitiveness of it but of course what we know in psychology is the environment is not the problem, it's how we relate to it is or where we could do some work and make a difference so absolutely I think she would do well to go into some sort of anger management programme and I understand that she has in the past but a re-go at that might be a useful thing but obviously it's not just about managing anger, it's important that we talk about anger in the right way when we try to manage it. It's not a bad behaviour because if it's bad we would beat ourself up when we do it so it's about being more accepting of self and being less hard on herself I think."

BA has been beset by problems with the high-tech check-in and baggage handling systems at the new 4.3 billion pound (8.6 billion U.S. dollar) terminal.

Hundreds of flights have been cancelled and tens of thousands of bags have gone missing, costing the airline about 16 million pounds since the terminal's opening last month.
