  15. 15. First identified by San Francisco cardiologists Meyer Friedman and Ray Rosenman, Type A behavior has two main components. Friedman states, “First, there is the tendency to try to accomplish too many things in too little time. Second, there is free-floating hostility. These people are irritated by trivial things; they exhibit signs of struggle against time and other people.” A key difference between Types A and B is that the former seem to react to several types of stress with larger increases in pulse rate and blood pressure. In one study, which included both personality types, subjects were forewarned that they would receive electric shock for errors on a difficult task: recalling long strings of numbers read aloud only once. Under this stressful condition, Type A individuals showed a significantly higher increase in pulse rate and blood pressure than did Type Bs. There are also contrasting patterns in social behavior. Type As tend to be more impatient with others and become angry when other people hold them back in any way. In general, Type As report feeling less comfortable around others than do Type Bs. They prefer to work alone rather than as a team, and they seem to resent being told what to do. Types As are more ready to do the opposite of what is demanded of them. What about Type A and work performance? Type As seem to work faster even when no pressure or deadline is involved. They complain less about hard work and report being less tired when it is finished. However, Type As do more poorly on tasks requiring patience or careful, considered judgment. Interestingly, surveys indicate that most members of top management are Type Bs, not Type As. Perhaps As don’t survive to make it! More likely, however, the impatient, hurried style of Type A is not compatible with the skills needed of top- level executives. In summary, Type As do better on tasks involving time pressure or solitary work. Type Bs may do better on tasks requiring complex judgment, accuracy rather than speed, and working as part of a team.
