Most analyses of reaction time (RT) data are conducted by using the statistical techniques with which psychologists are most familiar, such as analysis of variance on the sample mean. Unfortunately, these methods are usually inappropriate for RT data, because they have little power to detect genuine differences in RT between conditions. In addition, some statistical approaches can, under certain circumstances, result in findings that are artifacts of the analysis method itself. A corpus of…

### Comparing reaction time sequences from human participants and computational models

- PsychologyINTERSPEECH

This paper proposes a method, based on time series analysis, to filter the observed reaction times in order to separate the local speed effects, and shows that after such filtering the between-participant correlations increase as well as the average correlation between participant and model increases.

### Methods for dealing with reaction time outliers.

- SociologyPsychological bulletin
- 1993

It is concluded using quantitative examples that robust measures are much less affected by outliers and cutoffs than measures based on moments, and fitting explicit distribution functions as a way of recovering means and standard deviations is probably not worth routine use.

### Effects of truncation on reaction time analysis.

- MathematicsJournal of experimental psychology. General
- 1994

The authors report a promising maximum likelihood procedure for estimating properties of an untruncated distribution from a truncated sample and present in an appendix a set of procedures to control for truncation biases when testing hypotheses.

### A warning about median reaction time.

- MathematicsJournal of experimental psychology. Human perception and performance
- 1988

An important practical consequence of the bias in median reaction time is that sample medians must not be used to compare reaction times across experimental conditions when there are unequal numbers of trials in the conditions.

### Group reaction time distributions and an analysis of distribution statistics.

- MathematicsPsychological bulletin
- 1979

It is shown that this method of averaging is exact for certain distributions (i.e., the resulting distribution belongs to the same family as the individual distributions) and Monte Carlo studies and application of the method provide evidence that properties derived from the group reaction time distribution are much the same as average propertiesderived from the data of individual subjects.

### Reaction Time Distribution Analysis of Neuropsychological Performance in an ADHD Sample

- PsychologyChild neuropsychology : a journal on normal and abnormal development in childhood and adolescence

Results of this study suggest that the greater number of abnormally long RTs of children with ADHD reflect attentional lapses on some but not all trials and demonstrate why slower RT is found when estimates of variability assume normal Gaussian distributions.

The best-performing measure incorporates data from the IAT's practice trials, uses a metric that is calibrated by each respondent's latency variability, and includes a latency penalty for errors, and strongly outperforms the earlier (conventional) procedure.
