  1. The aim of the research is to find out whether or not interference does occur when participants try to identify the colour inks that colour words are written in.

The experimental hypothesis is that participants should take longer to identify the colour inks of colour words than other neutral words when tested.

The null hypothesis states that the difference in time taken between colour words and neutral words is due to chance.

  1. A directional hypothesis has been selected because there has been a lot of prior research in this field of study which indicates that this will be the direction of the results.

  1. The chosen research method is experiment and the design used is independent measures.

  1. Advantages of research methods are Replicability of procedures-other researchers can repeat the experiment to see if they get the same results, and another advantage is the Control over variables-this allows high levels of precision, cause and effects can be established quickly.

Disadvantages of research methods are Demand characteristics-participants try to make sense of the situation and may try to change their behaviour in order to give the experimenter what they want/or the opposite, another disadvantage is Lack of ecological validity-there are such high levels of control, the situation may become too artificial or staged.

5.   Participants will be assigned to each of the two groups randomly, by pulling names out of the

hat. This will ensure that there is no bias in the researcher’s allocation of participants to conditions

There are number of confounding variables that need to be controlled some possible confounding    

      variables may include sampling bias, participant motivation and fatigue and also environmental    

      changes i.e. noise and temperature.

6.         In order to deal with these you take the participant to a quiet area where they won’t be disturbed

       and where the temperature is just right not too cold or not too hot.

  1. Most psychological research requires that the minimum level of significance used should be P<0.05 which means that the probability of there results occurring by chance is less than 5%

   

      8.    Before carrying out the research we must also consider ethical concerns. Our experiment will  

         involve making sure that every participant gives informed consent before they take part. This

             means   they will know exactly what they will be required to do before they begin. Obviously,        

             you cannot tell a participant that they will do better in one condition rather than other because        

             might lead to demand characteristics. The experimenter must ensure that they have explained to  

             all participants in standerised instructions that their response will be kept confidential and    

             anonymous. Debriefing should be offered to all participants if they want them at the end of the  

             experiment. Participants should be made also aware of their right and withdrawal at any point in  

             the experiment.

                                               

AIM: The aim of this study is to find out whether or not interference does occur when participants try to identify the colour ink that colour words are written in.

METHOD:  An experiment was used for this study to find out if participants took longer to identify the colour ink of colour words than neutral words. The research design use for this was independent measures. To do this study the experimenter needed two word lists, a colour word list and a neutral word list, a colour test sheet, a stop watch standerised instructions and result table to put the times  in.

           To do this experiment the experimenter picked participants by opportunity sampling, he/she gave                

            Participants a colour test to see if they could identify the colours and then just picked up a colour                

        word list or a neutral word list and told the participant to read out the colour ink. After they took    

        part the experimenter thanked them for participating.

RESULTS: The experimenter found that the mean time for the colour words was 14.76 seconds and for the neutral words it was 10.6 seconds. The difference between the two word list was 4.16 seconds, this shows that the experimental hypothesis was right. Participants do take longer to identify colour words written in colour ink than neutral words written in colour ink. The Mann Whitney stats test result show that the level of significance was P<0.05 which means that the probability of the results being due to chance is less than 5%.

CONCLUSION: The result proves the hypothesis right. People take longer to identify colour words than neutral words. By doing this experiment as accurate as possible the experimenter has proved the hypothesis correct by providing a 95% accurate result. The level of significance was P<0.05.
