Adaptive working memory training did not enhance fluid intelligence or other cognitive abilities in healthy young adults. Improvements were limited to trained tasks, with no lasting benefits observed in non-trained cognitive measures.
Area of Science:
- Cognitive psychology
- Neuroscience
Background:
- Fluid intelligence is crucial for daily functioning but often considered fixed after childhood.
- Recent studies suggested potential cognitive gains from working memory training in adults.
Purpose of the Study:
- To replicate and expand on findings of improved fluid intelligence after working memory training.
- To investigate transfer effects to non-trained cognitive abilities.
Main Methods:
- Young adults participated in 20 sessions of adaptive dual n-back working memory training.
- Cognitive abilities and personality traits were assessed pre- and post-training.
- A control group received attentional tracking training, and another group had no training.
Main Results:
- Both training groups showed specific improvements on trained tasks, persisting for 6 months.
- No significant transfer of improvements was observed to fluid intelligence or other non-trained cognitive measures compared to the control group.
Conclusions:
- Adaptive working memory training does not enhance fluid intelligence or broader cognitive abilities in healthy young adults.
- Observed improvements are task-specific and do not generalize to untrained cognitive functions.
