Analysis of RTs when speed-accuracy trade-off leading to ceiling accuracy has occurred
I know that it is not desirable for behavioural data to show a (within-subjects) speed-accuracy trade-off, as it can lead to e.g. the wrong interpretation of a single subject's decreased RTs as ...

What to do when you have a speed-accuracy trade-off in your data?
Many studies report that a speed-accuracy trade-off (SATO) did not occur in the data since there is a positive correlation between RTs and error rates. In other words, people took longer to respond ...

Should raw response time data be transformed?
I am a statistician and doing some data analysis in cognitive sciences.
I noticed that the distribution of response time (RT) is chisq-squared-like, and I want to do Box-cox transformation to make it ...

Is there an extension of multinomial process models that incorporates response latencies?
In an experimental setting where a categorical response has to be given, the same response can, in theory, be generated by different latent processes. For example, in an experiment where participants ...

Correct measure of central tendency for reaction times analysis
I'd like to know what would be the less biased measure of central tendency to compare RTs in two conditions with a lot of trials (~700). Mean is really sensitive to outliers, and median really robust, ...

Analysis of parameter estimates from Ratcliff diffusion model
I would like to analyze a dataset in which subjects' reaction time and error rate have been recorded. In order to account for potential speed-accuracy trade-off I am planning to make use of the ...

How to analyze reaction times and accuracy together?
Is there a good way to analyze reaction times and accuracy together, other than MANOVA?
I have data from an experiment in which participants had to respond to stimuli in two different conditions in a ...
