It first temporarily removes the slowest RT from the distribution; then, the mean of the sample is calculated, and the cut-off value is calculated using a certain number of SDs around the mean, with the value for SD being determined by the current sample size.These different return-types are now implemented for all methods.only accepts data in wide format, but it is on my to-do list to allow long format entry.
The default values are the old required values meaning no code written for previous versions of This data is simulated, and has data from 32 subjects.This trimming can be done per condition (e.g., 2.5 SDs above the mean of each condition), per participant (e.g., 2.5 SDs above the mean of each participant), or per condition per participant (e.g., 2.5 SDs above the mean of each participant for each condition).In this function, the user declares a lower-bound on RT trimming (e.g., 150 milliseconds) and an upper-bound in standard deviations.This data frame should contain (at a minimum) columns that specify your participant numbers, your experimental conditions, your response time data, and your accuracy data.
In previous versions of your data had to contain columns with the same names used below.
The function also has some other important arguments: In this first example, let’s trim the data using criteria of RTs less than 150 milliseconds and greater than 2,000 milliseconds, with error trials removed before trimming commences.
