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… Expand

Non-Gaussian Distributional Analyses of Reaction Times (RT): Improvements that Increase Efficacy of RT Tasks for Describing Cognitive Processes
TLDR
Current results conform to a large literature demonstrating a more nuanced understanding of cognition afforded by non-Gaussian analysis of RT, compelling neuropsychology to enlarge assessment technology beyond the limitations of paper-and-pencil instruments. Expand

A Theory of Reaction Time Distributions
We develop a general theory of reaction time (RT) distributions in psychological experiments, deriving from the distribution of the quotient of two normal random variables, that of the task dicultyExpand
On the efficacy of procedures to normalize Ex-Gaussian distributions
TLDR
This paper presents different procedures to normalize data sampled from an Ex-Gaussian distribution in such a way that they are suitable for parametric tests based on the normality assumption. Expand

Comparing reaction time sequences from human participants and computational models
TLDR
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.

TLDR
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. Expand
Effects of truncation on reaction time analysis.
TLDR
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. Expand

TLDR
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. Expand
Group reaction time distributions and an analysis of distribution statistics.

  • Mathematics, Medicine

TLDR
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
TLDR
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. Expand

Response times are one of the most commonly collected dependent measures in empirical investigations of human cognition. Issues of response time analysis are becoming more important as models areExpand

TLDR
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. Expand
