1 Reaction Times and the Ex - Gaussian Distribution : When is it Appropriate ?
نویسنده
چکیده
Fitting of the ex-Gaussian distribution to reaction times and drawing conclusions from its estimated parameter values is becoming increasingly popular. The purpose of this note is to show that the ex-Gaussian distribution is inappropriate, given assumptions that are often made about the processes underlying reaction times. If so, the estimated parameters may be misleading, and the inferences from them incorrect.

The Semantic Stroop Effect: An Ex-Gaussian Analysis
Previous analyses of the standard Stroop effect (which typically uses color words that form part of the response set) have documented effects on mean reaction times in hundreds of experiments in the literature. Less well known is the fact that ex-Gaussian analyses reveal that such effects are seen in (a) the mean of the normal distribution (mu), as well as in (b) the standard deviation of the n...
متن کاملApplication of Non-Linear Functions at Distribution of Output SINR Gaussian Interference Channels
We have examined the convergence behavior of the LSCMA in some simple environments. Algorithms such as Multi¬ Target CMA, Multistage CMA, and Iterative Least Squares with Projection can be used for this purpose. The results presented here can form a basis for analysis of these multi-signal extraction techniques. Clearly, the variance and distribution of output SINR obtained with the LSCMA is al...
متن کاملSome Constraints on Reaction-Time Distributions for Sequential Processes*
It is perhaps surprising that if we know only that a process is accomplished by two or more functionally distinct subprocesses carried out in stages with stochastically independent durations, then we also know about some of the properties of the durations of that process. In particular, we know about aspects of the distributions of those durations and combinations of them. This chapter describe...
متن کاملEvaluation and Application of the Gaussian-Log Gaussian Spatial Model for Robust Bayesian Prediction of Tehran Air Pollution Data
Air pollution is one of the major problems of Tehran metropolis. Regarding the fact that Tehran is surrounded by Alborz Mountains from three sides, the pollution due to the cars traffic and other polluting means causes the pollutants to be trapped in the city and have no exit without appropriate wind guff. Carbon monoxide (CO) is one of the most important sources of pollution in Tehran air. The...
متن کاملAcross-task priming revisited: response and task conflicts disentangled using ex-Gaussian distribution analysis.
The differential effects of task and response conflict in priming paradigms where associations are strengthened between a stimulus, a task, and a response have been demonstrated in recent years with neuroimaging methods. However, such effects are not easily disentangled with only measurements of behavior, such as reaction times (RTs). Here, we report the application of ex-Gaussian distribution ...
