Training Flashcards
What is the brain training market estimated at?
Over 1 billion
What are the industry’s claims built on?
The idea of generalisability
What are the 3 effects of training?
1) Practice effects e.g. improved performance on trained task (not on actual memory, just the strategies used)
2) Near transfer e.g. improved performance on other tasks measuring the same ability like driving one car, can drive another
3) Far-transfer e.g. improved performance on other tasks measuring different abilites
Outline Jaeggi et al Study on whether brain training generalises
Trained participants showed improved performance on fluid intelligence tasks, with more training = more improvement
State 2 weaknesses of Jaeggi et al Study
1) Control group did no task at all
2) Drawing conclusions based on a single task ignores confounding variables
Outline Owen et al Study on whether brain training generalises?
He found evidence for practice effects e.g. improvements on the trained tasks, but no evidence for transfer, even when transfer tasks were cognitively closely related
Name 3 problems with the literature on brain training
1) Small sample sizes
2) Selective reporting of data
3) Failing to use appropriate control groups
What evidence is there to suggest that expectations influence outcomes, involving recruitment posters?
Participants only showed improvement when they were told in the recruitment poster what was being tested, and they were led to believe that the task would improve their intelligence, which creates sampling bias and placebo effects
Outline Shute et al’s findings on whether brain training generalises
Participants who played the video game for 8 weeks showed significant increase in spatial skill, but the participants who used a brain training programme for 8 weeks did not show increases on any measure
Do benefits of brain training programmes transfer to real world tasks?
No
Who do brain training programmes target, and why is this bad?
Parents with children who have ADHD, this is unethical and they are making promises they cant deliver
If depleting resources by performing a task influences performance of any other self-control task, what does this mean?
That building resources by practicing tasks will work in the same way
What did Denson et al find about a self-control training task and aggressive behaviour?
That participants who used their non-dominant hand between 8 and 6 every day for 2 weeks, had decreased aggressive behaviour but only for participants who were already high on aggression, and there was no significant difference or interaction effect
How many different quantification strategies of Denson et als competitive reaction time task was used?
156 in 130 publications
What was the Cohen’s d figure found by Hagger et al of how training reduced ego depletion, and what does this imply?
It was 1.07, and as .8 is large, this means that training does reduce ego depletion
