IQ Training Effectiveness: Overview and Key Findings
Research on the effectiveness of IQ training programs has produced mixed but generally promising results, with several types of interventions showing potential to improve cognitive abilities, especially in specific domains or populations.
SMART Training and Relational Skills Programs
SMART (Strengthening Mental Abilities with Relational Training) and similar relational skills training programs have been studied extensively for their impact on IQ. Multiple studies report that SMART training can lead to significant improvements in IQ scores, particularly in nonverbal reasoning and verbal skills among school-aged children and adolescents Colbert2018McLoughlin2020Zajonz2024. For example, one study found that students who received SMART training showed significant gains in Verbal IQ, Matrix Reasoning, and Vocabulary compared to control groups . Another study demonstrated that SMART training led to improvements in overall intellectual performance, working memory, and academic skills such as spelling and reading, outperforming a computer coding control group .
A systematic review and meta-analysis found a moderate overall impact of SMART training on nonverbal IQ, though it noted that the number of studies is small and many have methodological limitations, such as high risk of bias . Another large, stratified controlled trial found a mean increase of nearly 6 IQ points in the SMART group, compared to a non-significant increase in the control group . However, some research cautions that when controlling for baseline intelligence and attentional skills, the observed IQ gains may diminish, highlighting the importance of rigorous study design .
Working Memory Training
Working memory training (WMT) has also been explored as a method to boost IQ. One study with Brazilian children found that WMT led to gains in performance IQ and phonological awareness, but did not result in significant changes in overall cognitive performance . This suggests that while WMT may enhance certain cognitive skills, its effect on general intelligence may be limited.
Successful Intelligence Training
Programs based on Robert Sternberg's theory of successful intelligence, which target analytical, creative, and practical thinking, have shown positive effects on academic achievement, triarchic thinking, and socioemotional outcomes . Meta-analytic findings indicate that these programs benefit all students, with greater effects for gifted and older students. The largest gains were seen in socioemotional outcomes, followed by triarchic and achievement outcomes. The effectiveness was also influenced by participant selection, subject area, and grade level, with longer interventions showing smaller effects .
Emotional Intelligence (EI) Training
While not directly targeting traditional IQ, emotional intelligence training has been shown to be effective in improving EI, which is related to cognitive and social functioning. Meta-analyses and intervention studies confirm that EI can be enhanced through training, with moderate and stable effects over time . In workplace and sports settings, EI training has been linked to improved job performance and coaching efficacy, especially when programs are accessible and tailored to participants' needs Huda2021Hodžić2018.
Limitations and Considerations
Despite encouraging findings, several reviews highlight methodological concerns, such as small sample sizes, lack of randomization, and high risk of bias in many studies Roche2023Hayes2016. The durability and generalizability of IQ gains from training programs remain areas for further research. Additionally, the effectiveness of these interventions may depend on factors such as participant age, baseline abilities, and the specific cognitive domains targeted.
Conclusion
IQ training programs, particularly those focusing on relational skills (like SMART) and successful intelligence, show moderate effectiveness in improving certain aspects of intelligence, especially nonverbal reasoning and academic skills. Working memory and emotional intelligence training also offer benefits, though their impact on general IQ is less clear. The overall evidence suggests that while cognitive abilities can be enhanced through targeted training, the magnitude and persistence of these effects depend on program design, participant characteristics, and methodological rigor.
