Introduction The experiment with Meyer Friedman and Ray Rosenman1974 covered a nine year period using 3000 men aged 39 ? 59. Type A personalities tend to be more ambitious competitive time-conscious and tend to be perfectionists which therefore leads to a higher stressful lifestyle often are high achieving at work and therefore they predicted that they would have a higher predisposition to suffering from cardiac disease than those of a Type B personality who are more relaxed and easy going. Over the period it was determined that 70% of the men that died were Type A personalities.An Investigation To See If There Is A Difference Type A personalities are often people who are high achieving as a result of their personality traits. If this theory is looked at from a cardiology angle the theory was not widely accepted as there has been no definitive evidence that there is a link between high stress lifestyles and a pre-disposition to heart disease (does not take into consideration a genetic predisposition) however if we look at the classification of types of people the use of the Type A and Type B personality has become widely used. Aim The aim of this experiment is to demonstrate the difference in the way that Type A personalities will cope with that of Type B personalities whilst undergoing a midly stressful activity. Hypothesis Alternative Hypothesis (H1) There will be a significant difference between the pulse rates of Type A and Type B personalities when undertaking a mildly stressful activity. Null Hypothesis (H0) There will be no significant difference between the pulse rates of Type A and Type B personalities when undertaking a mildly stressful activity. Method This experiment uses a questionnaire to determine which personality type each individual is Type A or Type B. Once the personality type is determined each individual is asked to complete a dot to dot. The dot to dot will have a single number missing in order to create a mildly stressful situation. Any changes in the pulse rate will be used to measure the reaction to the situation. Participants I put a notice on the staff room door to ask my colleges if they would like to help me with an experiment it will only take 10 minutes to complete. The age range was between 19 ? 61 years that completed the experiment 13 females and 7 males the first ten did the questions and then the second ten did the questions. Once all have been done they would be put in to group type A or Type B the participants were informed who was in what group. The participants are a mixture of professional?s doctors nurses HCA?s. Materials Dot-to-Dot copy in appendix c Questionnaire copy in the appendix d A clock to count the pulse Pen and paper to wright down the results Procedure The first step is to give participants the opportunity to join in with the experiment so I as the investigator would put a notice on the notice board at work asking if they would like to join in on an experiment. Then when I had the first ten participants I would hand them a copy of the Questionnaire (appendix d) for them to do asking them if they don?t mind putting their name and age at the top this Questionnaire will help me to put them into type A or type B. and done the same with anther lot of ten. Then I went away to put them into their type A or B. then I had one person at a time doing the same dot-to-dot (appendix c) as I the investigator took their pulse before they start then the second time as they are looking for the missing number and third time after they had finished the dot-to-dot then record the results the pulse was counted by the minute hand for one minute ach time this was repeated twenty times throughout the day same environment. Once the experiment had finished I put up a on the notice board a thank you for your participation and if you would like to know the results or any questions about Type A or Type B come and see me. Discussion This experiment was conducted and have been completed by twenty participants male and female this had given me the results for the questioner and this showed most of the males was a type B and females are more Type A this I have learnt that most females are more organised and they are able to do more than the males as this shows that most of the males are more relaxed about things. The bar chart has shown that there is not much different between Type A or Type B. the experiment was a success but could been changed by selecting ten men and ten females to see what the difference between them. The advantages to the experiments is that it is easily repeated to get the results and is more consistent of standardised procedures that allows this to happen the disadvantage is that the experiment is a social situation which none of the participants are passive inanimate objects but are active individual thinking human beings that have a mind of their own. Conclusion The conclusion is that the bar chart has proofed the Null hypothesis there will be no significant difference between the pulse rates of Type A and Type B personalities when undertaking a mildly stressful activity. This could be the environment every one was doing the same experiment so they could have been getting bored or rushing as it was in a work environment where they are on their feet all day or just gone on to their break this could be the reason that there is not much change between type A and type B.
