Sebastian and Hernandez-Gill contemporary study AO3
Paragraph 1
A01
- what are the aims of the study? What is the sample of the study?
strength
- increased generalisability - large sample of Spanish children aged 5-17. This is a strength because the findings are representable across the Spanish education system increasing generalisability.
weakness
- ethnocentric - used a limited sample of participants who were born in Spain and now live in Madrid. This is a weakness because it discarded any children with learning impairments and wasn't representative for the rest of the population
paragraph 2
AO1
- describe the task. Describe the results and conclusion
strength
- standardised procedure - all participants were tested in the exact same way. This is a strength as is makes the study more reliable as every child went through the same process and complete the same tasks.
weakness
- low ecological validity - the task requires the children to remember sequences of digits to measure the phonological loop capacity, which is not representative of how we use our memories in everyday tasks. This is a weakness because the tests may be viewed as an artificial test of memory therefore lowering the ecological validity.
paragraph 3
strength
- useful applications - the results can be used in everyday setting, like when a teacher gives out instructions within a classroom. This is a strength because the instructions can be adapted and tailored for younger children's memories.
weakness
- ethical issues - there may be some issues around protection of vulnerable children and patients with dementia when completing the test. This is a weakness because they might not fully understand the purpose of the test putting them in distress challenging the responsibility principle
what is
it?
aim
- investigate the development of the phonological loop in Spanish and Anglo saxon children between 5-17 years old to see if capacity of memory increases with age
sample
- 570 participants (298 female, 272 males). All children were born in Spain and live in Madrid. They didn't have any learning difficulties or repeated any years of school
participants were divided into 5 different age categories
procedure
- a digit span task was used to measure the capacity of the phonological loop. The task consisted of random sequence digits read aloud by the experimenters at a rate of one per second. A digit was gradually added to increase the sequence
results
- the mean digit span for
5 years = 3.76 ]
6 years = 4.16
17 years = 5.91
showing that digit span increased with age
second study
this study was where researchers gathered data about the digit span of elderly people
sample
- 25 without impairment 25 with alzheimers 9 frontal lobe dementia
the comparison of results showed that the elderly had a higher digit span than 5 and 6 year olds. Alzheimers patients had a higher digit span that 5 year old but not higher than the other groups
