exam practice deck Flashcards
(a) Using the data below, explain the procedure used for the time sampling technique this study. (3 marks)
10 minutes
total observations - 40
20 observations for mum, 20 observation for dad
- The total observation time for each parent was 10 minutes.
- The psychologist made 20 observations for each parent.
- To generate 20 observations for each parent she must therefore have recordedher observation every ½ minute or every 30 seconds.
Write a debrief that the psychologist could read out to the participants. (6 marks)
- explanation of the aim
- information about the other condition – in an independent design people must know about the other condition
- general ethical considerations, eg respect for participants.
How could a psychologist analyse data from two conditions further by using percentages? (2 marks)
For each condition the number of x observed that condition in should be divided by the overall total observed in both conditions
The result for each condition should then be multiplied by 100 to give a %
(c) The sleep questionnaire used by the researchers had not been checked to see whether or not it was a reliable measure of sleep quality.
Explain how this study could be modified by checking the sleep questionnaire for test-retest reliability. (4 marks)
- the same participants would complete the sleep questionnaire on more thanone occasion
- each participants’ scores from the first occasion should be correlated with his /her results from the later occasion to be shown on a scattergraph to describe the correlation, with scores from the first test plotted on one axis and the scores from the second test plotted on the other axis
- the strength of the correlation should then be assessed using either aSpearman’s rho test (or a Pearson’s r test)
- the degree of reliability is then determined by comparing the correlation with thestatistical table to determine the extent of correlation – there should be a (strong) positive correlation between the two sets of scores.
Dominic is unhappy and lacks confidence. He thinks he is dumb and unattractive. His therapist says he lacks congruence. What is congruence and how much he Dominic achieve this? (4 marks)
- Rogers - an individual’s concept of the self must be similar to their ideal self to achieve self actualisation
- gap can be reduced if he develops a more healthy view of himself - unconditional positive regard from therapist or have more faith in himself
Calculate the sign test (calculated) value of s for the data in Table 1. Explain how you reached your answer. (2 marks)
- value of s is X
- The total for the least frequently occurring sign is the value of s = X
HOW TO ANSWER:
What is the operationalised dependent variable in this study? (2)
- YOU MUST FULLY OPERATIONALISE TO GET THE 2 MARKS
- e.g DV is whether the teachers thought their confidence in managing difficult behaviour was better, worse or the same after the course
Explain why statistical testing is used in psychological research. (2 marks)
researchers use statistical tests to determine the likelihood that relationship they found has occurred due to chance.
How can psychological research into depression impact the economy? (3 marks)
- Psychological research may lead to improvements in psychological health/treatment programmes which may mean that people manage their health better and take less time off work.
- Psychological research may lead to better ways of managing people whilst they are at work to improve productivity: e.g. research into motivation and workplace stress.
- ‘Cutting-edge’ scientific research may encourage investment from overseas companies into this country.
A - relay
Which neuron carries nerve impulses from the brain/spinal cord to muscles/glands?
C - motor
Which neuron carries nerve impulses between neurons?
A - relay
label X and Y
X - automatic nervous system
Y - somatic nervous system
sensory neurons carry impulses…
motor neurons carry impulses…
relay neurons carry impulses…
