Li - contemporary Flashcards
The aim of Li was?
To see the effects of high and low quality care on children’s cognitve abilities
What was the sample of Li?
1364 families from USA
At one month old the children were assessed on things like ethnicity, birth order, maternal age, parental education etc- why?
To account for those as extraneous/confounding variables
What was the observation conducted in Li?
O.R.C.E 44mins given in both infant and preschool ages
On the observation scores above what were deemed as ‘high quality’ (and below as ‘low quality’)
3
What traits did they look for to label something as ‘high quality’
Sensitivity to needs, cognitive stimulation and fostering exploration
When was the end of the infant period?
24m
What tests were conducted during the infant period?
Bayley mental development index
When was the end of the pre-school phase?
54m
What tests were conducted during the infant period?
Woodcock & Johnson cognitive achievement battery and Preschool Language scale
What result was found about high quality infant care?
Those in high quality infant care had improved cognitive scores
What was found about preschool?
High-quality preschool causes improvement in cognitive and language, reading, and maths results.
What was found about the children who went from high quality care in infancy to low quality care in pre-school
They lost out on the cognitive advantages they had (compared to the low-low kids) other than in memory
Where did Li get her data from?
The NICHD
A strength and a weakness of Li’s sample is?
Relatively large (so more generalisable) but ethnocentric (so less generalisable)
What is a strength for the reliablity of Li?
The various measures like ORCE, Bayley Developmental index etc were standardised making the study more reliable
This study has triangulation and so is more valid because?
There were various measures like Bayley Development index and Woodcock Johnson to compare the results against each other
Why did they look at things like birth order and maternal age at 1 month?
By looking for the confoudning variables like birth order they can be ruled out as a factor making this studies results about the impact of daycare
What is an issue with li using Secondary data?
The data wasn’t gathered by her so she cannot be fully sure it was gathered correctly and it might not have been fully operationalised in the best way for this study
Is Li high in ecological validity?
Yes- they are children in their normal daycare setting, so the results about the impact should apply to real life
Why would this study have low validity?
There will be lots of Extraneous Variables over the years of daycare which impact on the children’s development which cannot be accounted for
Why is Li reductionist?
It used 3.0 as a cutoff for high quality rather than anything more nuanced and only looked at cognitive development
This study mainly collects quantiative data, why is this good?
It allows for comparison of the effects of daycare which can be statistically analysed to see if it significant and it’s more objective
