CA - Real life outcomes Flashcards
What is the best predictor of academic achievement?
General intelligence / the g factor
What is the correlation between overall cognitive ability and academic achievement?
0.81 - this is about 64% of between individual variance in academic achievement is explained by students g factor
What is general intelligence positively associated with?
Better health and longevity. This results holds even after controlling for other socio-economic variables
What is ageing-associated cognitive decline?
The loss of cognitive performance solely due to chronological ageing
In cognitive decline, what skill shows more of a steep decline?
Gc sills show a significant less steep decline computed to Gf skills
What predictors explain 81% of the between-individual variance in the g factor at baseline?
Socio-economic, genetic, lifestyle, general health and fitness.
Why do we not know much about the predictability of cognitive decline?
The data is limited and ageing associated cognitive decline may be an intrinsically random phenomenon.
What is dementia?
Dementia is the impaired ability to remember, think or make decisions that interferes with doing everyday activities.
What is the most common type of dementia?
Alzheimers disease
What is the impact of dementia on the UK population?
It was the leading cause of death in 2022. In April 2023, about 5000 people died due to dementia in England and Wales.
When does dementia occur?
When cognitive decline reaches a certain threshold. Beyond the threshold, the individual stops being cognitively functioning.
What are biomarkers of dementias?
Can help to predict dementia - neuroimaging and biofluid indicators
What is a pro of biomarkers?
Better identifications of clusters of dementias so better tailored treatments
What is a con of biomarkers?
Little predictive power in the early phases
