ROW DATA

Row #: 1-114
Description: Each row represents one trial. There are 114 total trials. 
Data type: Each row contains the data for each trial, the column gives details of what is recorded for each trial. 

COLUMN DATA:

Column #: 1
Name: US presented 
Description: Which US was presented on each trial
Labels: 1 = goUS, 2 = nogoUS

Column #: 2
Name: Run length
Description: Run length measurement on each trial. Note the measurement is taken on the trial subsequent to the run
Labels: -5, -4, -3, -2, -1, 1, 2, 3, 4, 5
Note: 0 is presented for the first trial of every block as this does not provide a run length measure as there has not been any subsequent trials in the block

Column #: 3
Name: Block number
Description: There are different blocks of trials in this experiment in between which the participants were given a short break.
Labels: 1, 2

Column #: 4
Name: RT
Description: RT response made on each trial
Labels: -2 = nogoUS trial and a response was not made/required, a different negative number: an erroneous response i.e. responded when shouldn’t have, positive numbers = duration to make the correct response

Column #: 5
Name: Expectancy rating
Description: The expectancy rating made about the occurrence of the nogoUS during the CS period
Labels: Increasing scale from 1 to 9, 1 = I definitely do not think the nogoUS will be presented, 5  I do not know whether the nogoUS will be presented or not, 9  I definitely think the nogoUS will be presented. 
Note: 0 = no expectancy rating was made

Column #: 6
Name: Expectancy rating RT
Description: How long it took for the expectancy rating to made during the 5second CS period on each trial
Note: 0 = no rating was made
