Understanding how different people benefit from cognitive training and neurofeedback is really important. This can change based on things like age, skills, personality, and brain differences.

1. Age:

   • Younger adults usually get more from cognitive training. Studies show they can improve 20-30% in working memory.
   • Older adults may not see as much improvement. They typically improve about 10-15%.

2. Starting Skills:

   • People who start with better cognitive skills often make even bigger gains. Research says that if someone’s IQ increases by one standard deviation, they could see a 15-20% boost in how well they do in cognitive training.

3. Personality Traits:

   • Certain personality traits help with cognitive training. If someone is open to experience and careful, they usually do 25-30% better than others who don’t have those traits.

4. Brain Activity:

   • The success of neurofeedback can differ based on brain patterns. For example, people who have more alpha wave activity before training might improve their attention skills by 50-70% more than those with less alpha wave activity.

In short, knowing and taking these personal differences into account is very important. This helps make cognitive training and neurofeedback better for everyone since different people will see different results.
