AQA A LEVEL PSYCHOLOGY PAPER 2 with questions and answers

calculate the mean hours the baby slept at night to 2 significant figures, show working - 9.0 + 8.0 + 8.5 + 7.0 + 7.5 + 10.5 + 8.0 = 58.5 hours 58.5 / 7 = 8. 2SF = 8.3 hours Create a directional hypothesis for the experiment - Participants who watch a horror movie before bed are more likely to report 'yes' that they have had a nightmare when asked the following morning via text message, compared to participants who watched a romantic comedy film before bed. Describe what qualitative data is and give one advantage about using qualitative data? - Qualitative data is non-numerical in depth data that can be collected through open ended questions. A strength of this is that it helps to obtain rich detailed data - allowing researchers meaningful insights. Discuss the defense mechanism shown by Jed? - Displacement is when we redirect our hostile feelings onto something else because it is not appropriate to express their feeling towards the person or object in question. Jed can't take his frustration out on his teacher, who issued the detention and he displaced his feelings by kicking the locker. Explain why neurons travel in one direction during synaptic transmission? - Consequently, the information can only travel in this direction because the neurotransmitters are released from the vesicles at the end of the pre-synaptic neuron and bind to sites at the start of the post-synaptic neuron. This would make it impossible for information to flow in any other direction. Explain why repeated measures was used for this experiment? - A repeated measures design was used in this case so that the same participants took part in each condition (horror/romantic comedy). This way, there is less chance of individual differences, such as personality style or film preferences, affecting whether the participants reported a nightmare or not, and any differences found are thought to be the result of the IV affecting that person. Give one reason why schema's are not useful? - schemas may exclude information which doesn't conform to our prior expectations. As a result, we may form stereotypes which are difficult to shift, evenif new,disputing information is presented. This means we may not be processing the world around us accurately and may misjudge or represent a person or situation. Give one reason why schema's are useful? - When we're in unknown situations schemas help us know how to behave. So when we do not know what to do our schema fills in the gaps for us and allow us to process situations better. How can the experimental design be improved to increase validity? - In experimental research, a control group can be used to help improve validity. This can help to see if it is the IV influencing the DV. For example, they could have a control group who do nothing to ensure what differences are created are created due to whatever the researchers did, How would the participants be randomly split? - To split the sample randomly all participants names need to be thrown into a hat. Then the psychologist would select the number of pieces of paper from the hat according to the number of participants required for each group, in this case 25. The remaining 25 in the hat would form the second group.
