1) Per_disCS_SCR_Px

ROW DATA

Row #: 1-78
Description: Each three rows represent one trial. There are 26 trials in a block and so 78 rows in total. 
Data type: Each row contains the data for each component of a trial, the column gives details of what is recorded for each component.
Note: The data from the first 3 trials i.e. 9 rows, was not analysed as these trials were simply used to create a discrete CS context and were not part of the Perruchet run distribution. 

COLUMN DATA

Column #: 1
Name: SCR 
Description: Average SCR for that component of a trial. 
Note: This data is all from block 1

Colum #: 2
Name: Component identifier
Description: Component identifier for that trial. 3 measurements were taken in each trial. 
Labels: 1 = 5 seconds prior to hypothetical CS presentation on a US trial, 2 = 5 seconds of hypothetical CS presentation on a US trial, 3 = 5 seconds post hypothetical CS presentation on a US trial. 4 = 5 seconds prior to hypothetical CS presentation on a noUS trial, 5 = 5 seconds of hypothetical CS presentation on a noUS trial, 6 = 5 seconds post hypothetical CS presentation on a noUS trial. 
Note: This data is all from block 1.

Column #: 3
Name: SCR
Description: Average SCR for that component of a trial.
Note: This data is all from block 2

Colum #: 4
Name: Component identifier
Description: Component identifier for that trial. 3 measurements were taken in each trial. 
Labels: 1 = 5 seconds prior to hypothetical CS presentation on a US trial, 2 = 5 seconds of hypothetical CS presentation on a US trial, 3 = 5 seconds post hypothetical CS presentation on a US trial. 4 = 5 seconds prior to hypothetical CS presentation on a noUS trial, 5 = 5 seconds of hypothetical CS presentation on a noUS trial, 6 = 5 seconds post hypothetical CS presentation on a noUS trial. 
Note: This data is all from block 2.

2) Per_disCS_EXP_Px

ROW DATA

Row #: 1-26
Description: Each row represents one trial. There are 26 in total.
Data type: Each row contains the data for each trial, the column gives details of what is recorded for each trial. 
Note: The data from the first 3 trials i.e. 3 rows, was not analysed as these trials were simply used to create a discrete CS context and were not part of the Perruchet run distribution. 

COLUMN DATA

Column #: 1
Name: Expectancy ratings
Description: Expectancy rating made closest to the hypothetical CS presentation on that trial.
Labels: Increasing scale from 1 to 5, 1 = I definitely do not think the shock will happen, 3 = I do not know whether the shock will happen, 5 = I definitely think the shock will happen.
Note: 0 = no expectancy rating was made. Column 1 data is all from block 1.

Column #: 2
Name: Expectancy ratings
Description: Expectancy rating made closest to the hypothetical CS presentation on that trial.
Labels: Increasing scale from 1 to 5, 1 = I definitely do not think the shock will happen, 3 = I do not know whether the shock will happen, 5 = I definitely think the shock will happen.
Note: 0 = no expectancy rating was made. Column 1 data is all from block 2.

3) Per_disCS_Seqs_Px

ROW DATA

Row #: 1-23
Description: Each row represents one trial. There are 23 trials in each block. 
Data type: Each row contains the data for each trial, the column gives details of what is recorded for each trial.
Note: There are not 26 trials in these files as the 23 trials make up the Perruchet run distribution. An extra 3 trials were added at the start of each block, for half the participants this was CS-US, CS-noUS, CS-US, and the other half CS-noUS, CS-US, CS-noUS. The purpose of these 3 trials was to create a context with a discrete CS. Importantly these trials were not included in analysis as noted for the above files. 

COLUMN DATA

Column #: 1
Name: US presence
Description: Whether the US was presented on each trial.
Labels: 1 = US presented, 2 = US was not presented
Note: Block 1

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: -3, -2, -1, 1, 2, 3
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. Block 1.

Column #:3
Name: CS presence
Description: Whether the CS was presented on each trial.
Labels: 1 = CS presented, 0 = CS was not presented
Note: Block 1

Column #: 4
Name: US presence
Description: Whether the US was presented on each trial.
Labels: 1 = US presented, 2 = US was not presented
Note: Block 2

Column #: 5
Name: Run length
Description: Run length measurement on each trial. Note the measurement is taken on the trial subsequent to the run
Labels: -3, -2, -1, 1, 2, 3
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. Block 2.

Column #: 6
Name: CS presence
Description: Whether the CS was presented on each trial.
Labels: 1 = CS presented, 0 = CS was not presented
Note: Block 2

EXTRA NOTES
There is only one blocks worth of data (block 2) for P19, this is due to a computer malfunction during block 1 testing.
