Abstract: Intelligence (IQ) and speed of perceived time (SPT) are known to strongly correlate with numerous factors, including reaction time, inter-hemispheric transfer, and cerebellum volume. While these relationships are well understood, very little evidence has been presented for the relationship between intelligence and speed of perceived time themselves. This essay aims to determine the sources and strength of the relationship between IQ and SPT. The author posits that a negative correlation exists between IQ and SPT. A review of relevant literature provided insight into connections between multiple variables inversely correlated to IQ and SPT, respectively. A correlation of r = -0.606, R2  = 0.368 between IQ and SPT is predicted. A study of 117 nationally representative adult participants is used to support the predictive ability of intelligence based on SPT, reaction time (RT), and number memory (NM). The results demonstrate correlation between IQ and SPT as r = -0.654, R2 = 0.428, p < .0001, confirming the predicted value and supporting the primary hypothesis. This paper highlights the correlation between intelligence and speed of perceived time. It also highlights a 46.2% variability of IQ attributed to SPT and RT. Implications are discussed. Recommendations for future investigation are given.
