Relationship between Intelligence and Reaction Time; A Review Study

Although the relationship between reaction time and Intelligence quotient (IQ)scores involves an important part of theoretical information processing approaches towardsindividual differences, data obtained in this area are sparse or even non- congruent. Those whodo not believe the relationship between reaction time and intelligence, often argue that thereaction time is too simple, banal and non-intelligent and thus, it cannot reflect a variable withthe same sophistication, elegance and ambiguity of intelligence. In contrast, some believe thatthe reaction time is indicative of fluid intelligence has a growing trend until youth time(crescendo) and then steadily decreases (decrescendo). New researchers also believe that tojudge the relationship between intelligence and reaction time, the difference betweenprocessing time and reaction time should be considered.Method & Results: The present study, comparing recorded results of present studies andreviewing stated theories, seeks to answer this question "what is the relationship betweenreaction time and intelligence and whether reaction time can predict the differences in theintelligent structure?" Conclusion: The relationship between reaction time and IQ is toocomplicated and revealing a significant correlation depends on various variables (e.g.methodology, data analysis, instrument etc.).
