Distribution of human response times

Abstract: We confirm that distributions of human response times have power-law tails and argue that, among closed-form distributions, the generalized inverse gamma distribution is the most plausible choice for their description. We speculate that the task difficulty tracks the half-width of the distribution and show that it is related to the exponent of the power-law tail.

“…In the context of educational assessment, the lognormal distribution has been recommended to model RT of test items (van der Linden, ). However, Ma, Holden, and Serota () demonstrate that RT distributions have power‐law tails and argue that, among the closed‐form distributions, they are best fit by the generalized inverse gamma distribution. Ihlen () investigated RT distributions for a range of simple cognitive tasks and fitted the so‐called stable distribution to RT sequences involving autocorrelation structures.…”

“…The distributions are not symmetrical (not normal distribution), having a longer "tail". The tail is a typical fingerprint of the complexity (multiple feedback interactions with stochastic results) (172). The complexity depends on the patient and the disease's general conditions, so the distribution curves are only orienting the reader; they could not be exact.…”

“…Miritello [1] combs literature on statistics of human behavior in information dissemination and finds that the research method based on statistics of historical data is one of the effective methods to study the law of human behavior. Ma and others [2] confirmed that the tails of RT distributions exhibit power law behavior. Therefore, through collecting and analyzing broadcast data sent by 140 Twitter users, Salathé [3] and others based on the theory of psychology conclude that the emotions from friends and social awareness are highly correlated with individual information production behavior; that is, the emotions from neighbors have an important impact on information manufacturing behavior.…”
