mean_fixedSSD: Estimating SSRT using mean method for studies that use fixed...

In SSRTcalc: Easy SSRT Calculation

Description

Estimating SSRT using mean method for studies that use fixed (randomly chosen on each trial from a pre-determined set) stop-signal delays

Usage

mean_fixedSSD(df, stop_col, rt_col, acc_col, ssd_col, ssd_list)

Arguments

df	Dataframe with response time, accuracy, indication whether trial is stop or go, and delays for a given trial.
stop_col	Name of the column in the dataframe df that indicates whether a given trial is a "stop" or a "go" trial ( 0 = go, 1 = stop)
rt_col	Name of the column in the dataframe df that contains response time in seconds
acc_col	Name of the column in the dataframe df that contains accuracy of inhibition ( 0 = incorrect, 1 = correct)
ssd_col	Name of the column in the dataframe df that contains stop-signal delays
ssd_list	List of stop-signal delays used in the experiment

Value

Stop-signal reaction time corresponding roughly to 50 percent inhibition accuracy.

Examples

data(fixed)
sapply(split(fixed, fixed$new_id), mean_fixedSSD, stop_col = 'vol',acc_col ='acc',
rt_col = 'RT_exp', ssd_col = 'soa',ssd_list = c(0.1, 0.2,0.3, 0.4, 0.5, 0.6))
