mean_adaptiveSSD {SSRTcalc}

SSRT using mean method for studies with "adaptive" method of setting SSD

Description

Estimating SSRT using mean method for studies that use adaptive (increasing/decreasing by a given increment) stop-signal delays

Usage

mean_adaptiveSSD(df, rt_col, ssd_col, stop_col)

Arguments

df

Dataframe with response time, accuracy, indication whether trial is stop or go, and delays for a given trial.

rt_col

Name of the column in the dataframe df that contains response time in seconds

ssd_col

Name of the column in the dataframe df that contains stop-signal delays

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)

Value

Spline-interpolated stop-signal reaction time corresponding roughly to 50

Examples

data(adaptive)
sapply(split(adaptive, adaptive$new_id), mean_adaptiveSSD, stop_col = 'vol',
ssd_col = 'soa', rt_col = 'RT_exp')
